Technical Field

The invention relates to the technical field of automatic vehicle washing, in particular to a conveying device for a vehicle washing system and a vehicle conveying method.

Background

In the past, when people need to wash vehicles, people usually drive the vehicles to a special car washing station for washing. The cost is high and the consumed time is too long when the automobiles are cleaned in the car washing station. For this reason, automatic car washing systems have appeared on the market. The automatic car washing system is easy to operate and high in car washing efficiency, so that the automatic car washing system is very convenient for a driver to use in the process of going to and from work, for example.

The automatic car washing system requires a driver to start the car washing system according to the prompt. For example, in a tunnel car washing system, a driver is generally required to transport a car to a transport device and then wash the car with a car washing unit (e.g., a washing brush) while transporting the car by the transport device.

However, the existing transportation devices require drivers to perform driving operations in a certain manner (for example, the drivers are required to put into neutral or pull a hand brake), and due to different driving habits of different drivers, some drivers may not drive into the transportation devices in a predetermined manner, which may cause the transportation devices of the automatic car washing system to be unable to be started, and may even cause damage to the transportation devices or the cars.

Fig. 1 is a plan view schematically illustrating a transport device for a car wash system according to embodiment 1, fig. 2 is a schematic view illustrating a first wire body 100, fig. 3 is a cross-sectional view taken along a-a in fig. 2, and fig. 3 is a schematic view illustrating the first wire body 100 in a broken state, showing only a main portion of the first wire body 100, and for convenience of illustration, with reference to fig. 1 to 3, the transport device for a car wash system according to embodiment 1 for transporting a vehicle includes: a first wire 100, a second wire 101, and a third wire 102. The first line 100 is disposed at a rear end of the conveying device for the car washing system, and is used for carrying a vehicle which is driven in and stopped. The first string 100 can be driven only in the incoming direction of the vehicle. The second wire 101 is disposed in front of the first wire 100 in the incoming direction of the vehicle, and is butted against the first wire 100 to transfer the vehicle stopped at the first wire 100. The second wire 101 is driven in the incoming direction of the vehicle. The third wire body 102 is disposed in front of the second wire body 101 in the incoming direction of the vehicle, and abuts against the second wire body 101 and carries the vehicle that is driven and transferred by the second wire body 101. The third wire body 102 can be driven only in the incoming direction of the vehicle.

According to the conveying device for the vehicle washing system of the embodiment, the operation difficulty of the vehicle driver can be reduced. Specifically, since each wire body can be driven only in the incoming direction of the vehicle and at least the second wire body 101 has driving power, the vehicle driver may stop the vehicle (the driver may pull the handbrake or may put in neutral) after driving the vehicle onto the first wire body 100 or after driving the vehicle onto the first wire body 100 and the wheel in front of the vehicle in the incoming direction onto the second wire body 101. After the main portion of the vehicle stops at the first wire 100, the vehicle can be transferred to the second wire 101 by driving the second wire 101. While the second wire 101 transfers the vehicle, other vehicle washing devices (for example, a cleaning liquid spraying device, a washing device, a blow-drying device, etc., not shown) of the vehicle washing system are simultaneously or non-simultaneously operated to wash the vehicle. Further, after the second wire 101 transfers the vehicle to the third wire 102 (or partially transfers to the third wire 102), the driver may be notified that the vehicle may be started.

Therefore, in the whole car washing process, only the driver needs to execute the operation of parking and start the operation of leaving the car, and the operation difficulty of the driver of the car can be reduced.

In the transport device for a vehicle washing system according to the present embodiment, since the first wire 100 and the third wire 102 are each restricted to be drivable only in the incoming direction of the vehicle, the vehicle can be allowed to travel onto the first wire 100 or to travel out of the third wire 102 with its own power without causing the vehicle to slip on the first wire 100 or the third wire 102. Further, since the first wire 100 and the third wire 102 are each drivable in the incoming direction of the vehicle, the vehicle can be conveyed from the first wire 100 to the second wire 101 or from the second wire 101 to the third wire 102 mainly by the driving force of the second wire 101 even in a state where the vehicle is stopped. Further, since the first wire body 100 and the third wire body 102 are respectively restricted to be drivable only in the incoming direction of the vehicle, the wheel of the vehicle can be rotated relative to the first wire body 100 and the third wire body 102 in the neutral state of the vehicle, and even if the vehicle is pulled (parked), the wheel itself of the vehicle can drive the first wire body 100 and the third wire body 102 to rotate, so that a situation in which the wheel rubs against the first wire body 100 or the third wire body 102 does not occur.

Therefore, the conveying device for the vehicle washing system of the embodiment can not only improve the automation degree of the vehicle washing system, but also reduce the operation difficulty of the vehicle driver.

The vehicle of the present embodiment is not particularly limited, and examples thereof include: cars, SUVs, and buses, etc. Examples of the dimensions and wheelbase of a car include: class A vehicles, class B vehicles, class C vehicles, class D vehicles and the like.

The direction of approach of the vehicle described in the present embodiment refers to the direction in which the vehicle enters the vehicle washing system, and the direction of approach and the direction in which the vehicle leaves the vehicle washing system may be the same direction. In the present embodiment, the forward and backward direction indicates the direction in which the vehicle enters (or the direction in which the vehicle leaves). The direction along the traveling direction is the front, and the direction opposite to the traveling direction is the rear.

The manner in which the vehicle enters the car wash system is not particularly limited, and for example, the vehicle may enter the car wash system in a normal driving manner (i.e., the vehicle head enters the car wash system first), or may enter the car wash system in a reverse driving manner (i.e., the vehicle tail enters the car wash system first). In the present embodiment, the wheel (which may be the front wheel or the rear wheel) that first enters the vehicle washing system is referred to as the wheel in front of the incoming direction. In the following embodiments, the vehicle enters the car wash system in a normal running manner as an example.

The car washing system according to the present embodiment may be a tunnel type car washing system, and in the present embodiment, description will be given mainly on a conveyor device for a car washing system, and other devices of the car washing system according to the present embodiment, for example, a barrier gate, a sensor device for sensing whether a vehicle is in a stopped state, in-position, or out-of-position, other car washing devices (for example, a device for spraying a washing liquid, a washing device, and a blow-drying device), and an alarm device, may refer to a conventional tunnel type car washing system. Except where necessary, are not described in detail herein.

The first wire 100, the second wire 101, and the third wire 102 may be provided on a welded base 103, or may be provided directly on a ground 104. The base 103 has a longitudinal direction extending in the front-rear direction. Taking the base 103 and the first string 100 as an example, for example, two bases 103 may be spaced apart from each other in the left-right direction, and two first strings 100 may be provided and disposed on the bases 103 in the left-right direction. One of the first bobbins 100 supports a left front wheel and a left rear wheel of the vehicle, and the other bobbin 100 supports a right front wheel and a right rear wheel of the vehicle. The distance between the two first strings 100 in the left-right direction is not particularly limited as long as it can be applied to the width of the vehicle to be cleaned. By providing each line body on the base 103, the construction difficulty of the conveying device can be reduced. In addition, the application scene of the car washing system can be expanded.

The first wire body 100 (and the third wire body 102) will be described below.

Fig. 4 is a principal part schematic view of a portion of a front end portion of the first wire body 100, fig. 5 is a principal part schematic view of a portion of a rear end portion of the first wire body 100 of fig. 2, with reference to fig. 4, 5, and with continuing reference to fig. 3, in some embodiments, the first wire body 100 and the third wire body 102, respectively, have: a first conveyor chain 105, a first support assembly 106, and a second support assembly 107. Wherein the first conveyor chain 105 is used to support the vehicle. The first support member 106 supports one of the front end portion and the rear end portion of the first conveyor chain 105. The second support member 107 supports the other end of the front end portion and the rear end portion of the first conveyor chain 105. At least one of the first conveyor chain 105, the first support member 106 and the second support member 107 is arranged to be drivable only in the incoming direction of the vehicle.

The first wire 100 and the third wire 102 have substantially the same configuration, and for convenience of description, the first wire 100 is mainly used as an example for description, and the third wire 102 is referred to only when necessary.

The first transfer chain 105 may be a slat type transfer chain, and the first transfer chain 105 as the slat type transfer chain may include: a first chain body 108 and a plurality of first loading plates 109 respectively mounted to the first chain body 108. Specifically, for example, the first chain main body 108 includes two, and is provided at an interval in the left-right direction. The first chain body 108 may be a roller chain with a mounting attachment 110 for heavy-duty type conveyance. The first carrier plate 109 is used to carry a vehicle, and both ends of the first carrier plate 109 in the left-right direction are respectively mounted to the mounting attachments 110 of the first chain main body 108. Thus, a plate conveyor chain having a constant bearing width in the left-right direction can be formed.

Further, the first conveyor chain 105 may be another plate conveyor chain such as a commercially available floor chain. By using the plate-type conveying chain to support the vehicle, the area of each line body for supporting the vehicle can be widened, the difficulty of a vehicle driver entering the conveying device of the vehicle washing system is reduced, and meanwhile, the universality of the conveying device can also be improved.

Referring to fig. 3, the first string 100 is generally oblong as a whole, that is, the first conveying chain 105 is generally oblong as a whole, as viewed from the left-right direction. For convenience of explanation, a portion of the first conveyor chain 105 running to an upper portion of the first string 100 for supporting the vehicle is referred to as an "upper conveyor chain 105 u", and a portion of the first conveyor chain 105 running to a lower portion of the first string 100 is referred to as a "lower conveyor chain 105 d". The side of the upper conveyor chain 105u that supports the wheels is referred to as the "outer side", and the side facing the lower conveyor chain 105d, opposite the "outer side", is referred to as the "inner side". Similarly, the side of the lower conveyor chain 105d facing downward is referred to as the "outer side", and the side opposite the "outer side" is referred to as the "inner side".

In some embodiments, in order to increase the carrying capacity of the first string 100, a supporting wheel 111 is disposed on the inner side of each first carrying plate 109. A support base 112 is provided on a lower portion of the upper conveyor chain 105u of the first conveyor chain 105, and the support wheel 111 is supported by the support base 112 and travels along the support base 112. The support base 112 is provided on the base 103 and is located between the upper conveyor chain 105u and the lower conveyor chain 105d in the up-down direction. The support base 112 may be an elongated member that is formed by machining a steel-made material such as a channel, an i-beam, a square tube, or a flat tube and extends in the longitudinal direction of the base 103.

Therefore, by providing the support wheels 111 supported by the support base 112 on the lower side of each first carrier plate 109, the carrying capacity of the first wire 100 can be greatly improved, and the first wire 100 can be prevented from collapsing in the vertical direction. In addition, by rolling the supporting wheels 111 along the supporting seat 112, the smoothness of the operation of the first string body 100 can be improved, thereby improving the comfort of a driver who drives a vehicle to the first string body 100.

Although the above description has been made by taking a slat conveyor as an example, the present invention is not limited to this. For example, the first conveyor chain 105 may also select, for example, a plurality of rows of roller chains or the like.

Although the above description has been made by taking a transmission chain as an example, the present invention is not limited to this. When the strength is sufficient, a belt line or the like may be used for each wire body.

Referring to fig. 4, with additional reference to fig. 3, a first support assembly 106 may be disposed at a front end portion of the first conveyor chain 105. The first support assembly 106 includes: a first driving wheel 113, a first supporting shaft 114 and two first bearing housings 115. The first driving wheels 113 include two left and right driving wheels, and the first driving wheels 113 are engaged with the first conveying chains 105 in the left and right driving directions, respectively. The first drive wheel 113 is configured according to the model of the first chain body 108, and for example, in the case where the first chain body 108 selects a roller chain, the first drive wheel 113 is a sprocket capable of engaging with the roller chain. The first support shaft 114 extends in the left-right direction and supports the two first drive wheels 113 in the left-right direction. Two first bearing housings 115 are provided on the base 103 at intervals in the left-right direction, respectively, and the first bearing housings 115 support both ends in the axial direction of the first support shaft 114.

In the case that the first wire body 100 requires power for active driving, the first wire body 100 may further include a first driving motor 116, and the first driving motor 116 is mounted on the base 103 and connected with the first support shaft 114 of the first support assembly 106. Thus, the first chain main body 108 can be driven by the first drive motor 116. By providing the first drive motor 116 for driving the first chain main body 108 in operation, smooth transfer of the vehicle from the first wire body 100 to the second wire body 101 can be achieved. Since the vehicle can be transferred to the second wire body 101 only by stopping at least a part (for example, a front wheel part) of the vehicle on the first wire body 100, the difficulty of operating the vehicle by the driver of the vehicle can be further reduced.

Although the example in which the first wire 100 includes the first drive motor 116 has been described above, the present invention is not limited to this. For example, when the driver is requested to drive at least the front wheel of the vehicle to the second wire 101, the second wire 101 has independent power (described later), and therefore the first wire 100 may not have driving power and the entire vehicle partially positioned in the first wire 100 may be transferred to the second wire 101 by passing through the second wire 101.

In addition, in the case where first wire body 100 (or third wire body 102) does not have power for active driving, when first wire body 100 (or third wire body 102) is described as being driven, it should be understood that first wire body 100 (or third wire body 102) is driven by friction force from a wheel of a vehicle, so that there is no sliding friction between the wheel of the vehicle and first wire body 100 (or third wire body 102) (for example, in the case where first wire body 100 (or third wire body 102) has a plate-type transmission chain), or rolling friction between the wheel of the vehicle and first wire body 100 (or third wire body 102) (for example, in the case where first wire body 100 (or third wire body 102) has support rollers 125).

Referring to fig. 5, with additional reference to fig. 3, a second support assembly 107 may be disposed at a rear end portion of the first conveyor chain 105. In order to be able to independently adjust the tension degree of the two first chain bodies 108 on the left and right sides, the second support assembly 107 may include two, which are respectively provided on the left and right sides of the base 103. The first support assembly 106 includes: a second transmission wheel 117, a second support shaft 118 and a second bearing housing 119. Wherein the second transmission wheel 117 is engaged with the first transmission chain 105 (i.e., a portion of the first chain body 108), the structure of the second transmission wheel 117 may be selected to be the same as that of the first transmission wheel 113. The second support shaft 118 extends in the left-right direction and supports the second transmission wheel 117. The second bearing housing 119 supports a second support shaft 118. Further, the second support assembly 107 is provided with a tension portion 120 for adjusting the tension of the first chain body 108, and the tension portion 120 can adjust the tension of the first chain body 108 by adjusting the position of the second bearing housing 119 in the left-right direction, for example. The tensioning 120 can be selected from known tensioning devices on chain drives.

As described above, the first string 100 can be driven only in the incoming direction (forward direction) of the vehicle. Specifically, it is possible to set at least one of the first conveyor chain 105, the first support assembly 106, and the second support assembly 107 to be drivable only in the incoming direction of the vehicle.

With continued reference to fig. 3, 4, in some embodiments, for example, the first conveyor chain 105 may be made drivable only in the incoming direction of the vehicle. Specifically, for example, a check device 121 may be provided on the support base 112, and at least a portion of the support wheels 111 provided at the inner side of the first carrier plate 109 is restricted by the check device 121 to travel only in the incoming direction of the vehicle, so that the first transmission chain 105 can be driven only in the incoming direction of the vehicle. The check device 121 may include, for example, a check piece 122 that can swing and a spring member (not shown) that urges the check piece 122 in an upper direction, and when the support wheel 111 provided inside the first carrier plate 109 of the first transmission chain 105 rolls in a front direction of the support seat 112, the support wheel 111 presses the check piece 122 and rides over the check piece 122. When the support wheel 111 passes over the check block 122, the check block 122 is returned in the upward direction by the spring member. This can restrict the support wheel 111 from rolling in the rear direction of the support base 112, and the first transmission chain 105 as a whole is restricted from running in the rear direction by the check device 121.

The number and position of the check means 121 are not particularly limited as long as the first transmission chain 105 can be restricted from running in the direction opposite to the incoming direction. However, it is preferable that the check means 121 are uniformly distributed in plurality at intervals in the front-rear direction of the support base 112. Further preferably, the distance between two adjacent check devices 121 in the front-rear direction is set to be the same as the distance between two adjacent support wheels 111. Further, in order to save cost, the distance of the check device 121 in the front-rear direction may also be set to an integral multiple (e.g., 2 times or 3 times) of the distance between the two support wheels 111 as needed. In order to be able to cover the vehicle as a whole, the total length of the non-return means 121, which is distributed in the front-rear direction, is greater than the distance between the front and rear wheels of the vehicle.

By providing the backstop device 121 on the support seat 112, which restrains the support wheel 111, the risk of the first conveyor chain 105 being pulled apart can be greatly reduced. Specifically, while the vehicle is driven in the forward direction into the first line body 100 and carried by the first carrier plate 109, the wheels of the vehicle simultaneously exert a force in the rearward direction on the first carrier plate 109. Particularly, when the vehicle is at a high speed or suddenly brakes, the wheel of the vehicle applies a large rearward force to the first carrier plate 109. In the case where the first transmission chain 105 is used for a long period of time (particularly, is eroded by a liquid having certain corrosiveness such as soapy water for car washing), there is a possibility that a screw for connecting the first bearing plate 109 and the first chain body 108, or a connecting pin for connecting adjacent two links of the first chain body 108 may be reduced in strength due to rusting or the like. In the present embodiment, since the check device 121 is provided to directly restrict the movement of the first loading plate 109 in the rear direction, it is possible to realize that the blocking force of the check device 121 directly acts on the first loading plate 109 without being transmitted through the first chain body 108. That is, it is possible to suppress the rearward force applied to the first carrier plate 109 by the wheel of the vehicle from being applied to the connecting position of the first carrier plate 109 and the first chain body 108 or the position of the connecting pin between the link of the first chain body 108 and the link. Thereby, it is possible to effectively suppress the screws connecting the first bearing plate 109 and the first chain main body 108 in the first transmission chain 105 or the connecting pins of the first chain main body 108 connecting the adjacent two links from being cut.

In some embodiments, the first support assembly 106 may also be configured to be drivable only in the incoming direction of the vehicle. For example, at least one of the bearings of the two first bearing housings 115 is a one-way bearing that rotates only in the incoming direction of the vehicle. From the viewpoint of balancing the force, it is preferable that the bearings of both the first bearing blocks 115 are selected to be one-way bearings. The type, specification, and the like of the one-way bearing are not particularly limited, and commercially available one-way bearings may be selected as necessary. By selecting the one-way bearing, the first support shaft 114 supported by the two first bearing housings 115 is restricted to be drivable only in the incoming direction of the vehicle, and the cost of the first bobbin 100 can be reduced while enabling the one-way driving of the first bobbin 100.

With continued reference to fig. 4, further, as an example of the first support assembly 106 being limited to being drivable in only the incoming direction of the vehicle, it is also possible to have the first support shaft 114 or the first drive wheel 113 being limited to being rotatable in only the incoming direction of the vehicle by the first ratchet-pawl mechanism 123. The first ratchet-pawl mechanism 123 includes, for example, a first ratchet wheel 123a and a first pawl 123 b. The first ratchet wheel 123a may be coaxially mounted on the first support shaft 114 or the first driving wheel 113. First pawl 123b can be mounted in any position that cooperates with first ratchet wheel 123a, for example first pawl 123b can be mounted to base 103.

In some embodiments, the second support assembly 107 may also be arranged to be drivable only in the incoming direction of the vehicle. Also, for example, the bearing of the second bearing block 119 may be a one-way bearing that rotates only in the incoming direction of the vehicle. Further, the second support shaft 118 or the second transmission wheel 117 of the second support assembly 107 is also constrained to rotate only in the incoming direction of the vehicle by a second ratchet-pawl mechanism (not shown). The second ratchet-pawl mechanism may be designed with reference to the first ratchet-pawl mechanism 123 and will not be described in detail here.

It should be noted that the first conveying chain 105, the first support assembly 106, and the second support assembly 107, which are described above independently, are only examples that can be driven in the incoming direction of the vehicle, and any combination thereof is possible. For example, the first conveyor chain 105 and the first support assembly 106 may be arranged to be drivable only in the incoming direction of the vehicle, respectively. Alternatively, the first support member 106 and the second support member 107 may be provided so as to be drivable only in the incoming direction of the vehicle, or the like.

With continuing reference to fig. 4 and with additional reference to fig. 2, in some embodiments, at least a portion of the first carrier plate 109 of the plurality of first carrier plates 109 of the first transmission chain 105 is provided with a first limiting block 124 for limiting a wheel of the vehicle. In the case where the first restriction blocks 124 are located at the position of the upper conveyor chain 105u among the first conveyor chains 105 with the operation of the first conveyor chain 105, the distance in the front-rear direction of the adjacent two first restriction blocks 124 is, for example, slightly larger than the distance between the centers of the front and rear wheels of the vehicle. Further, in the case of increasing the number of the first restriction pieces 124, the distance in the front-rear direction of the adjacent two first restriction pieces 124 may be slightly larger than, for example, half the distance of the centers of the front and rear wheels of the vehicle.

Accordingly, the slip of the vehicle relative to the first string member 100 due to the wheel slip or the non-pulling of the hand brake by the driver can be suppressed, the positional accuracy of the vehicle relative to the first string member 100 can be improved, and the risk of an unexpected alarm, an emergency stop, or the like occurring in the transportation device or even the car wash system due to the positional deviation of the vehicle relative to the first string member 100 can be reduced. In particular, in the case where the first wire 100 or the second wire 101 is operated, the slip of the vehicle with respect to the first wire 100 can be suppressed very effectively.

Although the first wire 100 and the third wire 102 have been described above as including the first transmission chain 105, the form of the first wire 100 and the third wire 102 is not limited to this.

Fig. 6 is a main schematic view of another embodiment of the transport device for a car washing system, and referring to fig. 6, for example, the first wire 100 and the third wire 102 may respectively have: a plurality of support rollers 125 and a plurality of third support assemblies 126. Wherein a plurality of support rollers 125 are arranged in the incoming direction of the vehicle and serve to support the vehicle. The third support assemblies 126 support the support rollers 125, respectively. For example, the plurality of third support members 126 are divided into two groups in the left-right direction, and are respectively provided on the base 103. The third support assemblies 126, which are located on the left side of the base 103, support the axial left ends of the support rollers 125, respectively. The third support assemblies 126, which are located at the right side of the base 103, support the right-side ends of the support rollers 125 in the axial direction, respectively. For each third support assembly 126, a well-known bearing support assembly for supporting the roller may be selected, which is not described in detail herein. Further, the bearing of the third support assembly 126 is a one-way bearing that rotates only in the incoming direction of the vehicle. Thereby, the support rollers 125 can be rotated only in the incoming direction of the vehicle.

In the present embodiment, since the first wire body 100 and the third wire body 102 respectively use the support rollers 125 that rotate only in the incoming direction of the vehicle, the vehicle can be allowed to travel onto the first wire body 100 or out of the third wire body 102 with its own power without causing the vehicle to slip on the first wire body 100 or the third wire body 102. Further, in the case where the vehicle is conveyed by the second wire 101, the wheel of the vehicle can rotate relative to the support rollers 125 in the neutral state of the vehicle, and even if the vehicle is pulled (parked), the wheel itself of the vehicle can drive the support rollers 125 to rotate, so that there is no occurrence of a tire rubbing of the wheel relative to the first wire 100 or the third wire 102. Therefore, the tire abrasion of the wheel can be effectively prevented, and the operation difficulty of a vehicle driver is reduced.

The second wire body 101 will be described below.

Fig. 7 and 8 are schematic diagrams of another embodiment of a conveying device for a car washing system, wherein fig. 7 illustrates a docking position of a second wire 101 and a third wire 102, fig. 8 illustrates a docking position of a first wire 100 and a second wire 101, and referring to fig. 7 and 8, in some embodiments, the second wire 101 includes: a second conveyor chain 127, a fourth support assembly 128, a fifth support assembly 129, and a second drive motor 130. Wherein the second conveyor chain 127 supports the vehicle. The fourth support assembly 128 supports one end of the second transfer chain 127 among the front and rear ends thereof, and the fourth support assembly 128 has a transmission shaft 131 for supporting the second transfer chain 127. The fifth support assembly 129 supports the other end of the second conveyor chain 127 among the front and rear ends. The second driving motor 130 is connected to the driving shaft 131.

The structure of the second conveyor chain 127 is substantially the same as the structure of the first conveyor chain 105. For example, the second conveyor chain 127 may be a plate conveyor chain. The second conveyor chain 127, which is a plate conveyor chain, may also comprise: a second chain body 132 and a plurality of second carrier plates 133 respectively mounted to the second chain body 132. Similarly, in order to improve the carrying capacity of the second wire 101, the support wheels 111 may be provided inside each of the second carrier plates 133. The lower portion of the second conveyor chain 127 is also provided with a support base 112, and the support wheels 111 are supported by the support base 112 and run along the support base 112.

In addition, the second transmission chain 127 may also include a plurality of second limiting blocks 134, and the plurality of second limiting blocks 134 are mounted to the outer sides of the different second bearing plates 133 at regular intervals along the length direction of the second chain main body 132. In the case where the second restriction blocks 134 are located at the upper portion of the second conveyor chain 127 in accordance with the operation of the second conveyor chain 127, the distance in the front-rear direction between the adjacent two second restriction blocks 134 is set to be slightly larger than the diameter of the wheels of the vehicle. For example, the adjacent second restricting blocks 134 may be respectively mounted on the second carrier plate 133 with an interval of 3 to 5 second carrier plates 133 with respect to the second carrier plate 133.

By providing the second restricting block 134 on the second carrier plate 133, it is possible to suppress the slip of the vehicle with respect to the second wire 101 when the second wire 101 is running, due to the slipping of the wheel, or when the driver does not pull the hand brake, or the like. Therefore, the position accuracy of the vehicle relative to the second linear body 101 can be improved, and the risks of accidental alarm, sudden stop and the like of the conveying device and even a car washing system caused by the position deviation of the vehicle relative to the second linear body 101 are reduced.

The fourth support assembly 128 may be designed with reference to the structure of the first support assembly 106. For example, the fourth support assembly 128 may be disposed at a front end portion of the second conveyor chain 127. Further, in the present embodiment, the bearing of the fourth support assembly 128 may be either a one-way bearing or a two-way bearing.

Likewise, the fifth support assembly 129 may be designed in the structure of the second support assembly 107 and will not be described in detail herein.

With continued reference to fig. 8, in some embodiments, a first transfer wire body 135 is provided at the interface location of the first wire body 100 and the second wire body 101. A second relay body 136 is provided at the butt joint position of the second body 101 and the third body 102. The first relay unit 135 and the second relay unit 136 have substantially the same structure, and the first relay unit 135 is mainly used as an example for description, and the second relay unit 136 is referred to only when necessary.

The first transfer line body 135 and the second transfer line body 136 include, for example, transfer rollers 137 distributed in the front-rear direction, respectively. The number of the transfer rollers 137 is not particularly limited, and may be, for example, 1 to 5. In addition, the transfer roller 137 may also be supported by a one-way bearing to be driven only in the incoming direction of the vehicle. In addition, in the case that the first limiting block 124 is disposed at the outer side of the first bearing plate 109 and/or the second limiting block 134 is disposed at the outer side of the second bearing plate 133, an avoiding groove 138 may be formed on the transfer roller 137. Thereby, the first restriction piece 124 and/or the second restriction piece 134, and the intermediary rotation roller 137 can be prevented from interfering. By arranging the transfer rollers 137, the gap between the first transfer line body 135 and the first line body 100 and the second line body 101 can be reduced, and the smooth transition of the vehicle at the butt joint position of the first line body 100 and the second line body 101 is realized. Moreover, since the relay rollers 137 are driven only in the incoming direction of the vehicle, even when the vehicle is pulled (parked), the wheels themselves of the vehicle can drive the relay rollers 137 to rotate, so that the tire is not worn with respect to the first relay wire body 135 or the second relay wire body 136. Therefore, the tire scuffing of the wheel can be effectively prevented.

Hereinafter, a vehicle conveying method in which the first string 100 of the conveying device has a car washing system with active driving power will be described.

The vehicle conveying method based on the conveying device for the car washing system according to embodiment 2 includes the steps of:

s10: after the vehicle stops at the first wire 100, the car wash system issues a work order, wherein the first wire 100 can only be driven in the incoming direction of the vehicle.

S11: based on the work order, the first wire body 100 and the second wire body 101 operate so that the vehicle is transferred from the first wire body 100 to the second wire body 101, wherein the second wire body 101 is disposed in front of the first wire body 100 in the incoming direction of the vehicle and is butted against the first wire body 100.

S12: the second wire body 101 continues to operate so that at least the wheel in front of the incoming direction of the vehicle is transferred to the third wire body 102, wherein the third wire body 102 is disposed in front of the second wire body 101 in the incoming direction of the vehicle and is butted against the second wire body 101, and the third wire body 102 can be driven only in the incoming direction of the vehicle.

S13: after at least the wheels in front of the vehicle in the incoming direction are transferred to the third line 102, the vehicle wash system issues a command that the vehicle can be started.

According to the vehicle conveying method of the embodiment, the operation difficulty of a vehicle driver can be reduced. Specifically, when the driver of the vehicle drives the vehicle onto the first string 100, the vehicle may be stopped (the driver may pull the parking brake or may shift the neutral position). The vehicle is transferred to the second wire 101 through the first wire 100 and the second wire 101. While the second wire 101 transfers the vehicle, other vehicle washing devices (e.g., a device for spraying a washing liquid, a scrubbing device, and a blow-drying device, etc.) of the vehicle washing system are simultaneously operated to wash the vehicle. Further, after the second wire 101 transfers the vehicle to the third wire 102 (or partially transfers to the third wire 102), the driver may be notified that the vehicle may be started.

Further, since the first wire body 100 and the third wire body 102 are respectively restricted to be drivable only in the incoming direction of the vehicle, the wheel of the vehicle can be rotated relative to the first wire body 100 and the third wire body 102 in the neutral state of the vehicle, and even when the vehicle is pulled for a handbrake (parking), the wheel itself of the vehicle can drive the first wire body 100 and the third wire body 102 to rotate, so that a situation in which the wheel is worn relative to the first wire body 100 or the third wire body 102 does not occur. Thus, the vehicle conveying method according to the present embodiment can reduce the operation difficulty of the vehicle driver by only requiring the driver to perform the parking operation and the vehicle departure starting operation. Before step S10, the position of the vehicle may be detected by, for example, a photoelectric sensor device, and the control device of the car wash system issues a command to the driver to stop the vehicle after the vehicle reaches a specified position of the first string 100. The car washing system can remind a driver of parking through modes such as voice reminding and screen display, and can remind the driver of parking, folding a rearview mirror and the like while reminding the driver of parking.

In step S10, the work orders issued by the car washing system include, but are not limited to: an operation command for operating the first drive motor 116 of the first wire 100, operating the second drive motor 130 of the second wire 101, and starting another car washer.

In step S11: the first and second bobbins 100 and 101 start the operation of the first and second driving motors 116 and 130 based on the operation command, so that the vehicle is transferred from the first bobbin 100 to the second bobbin 101. In the present embodiment, the rotation speed of the first driving motor 116 may be the same as the rotation speed of the second driving motor 130 during the transfer of the vehicle from the first wire body 100 to the second wire body 101. Thereby, the vehicle can be smoothly conveyed from the first wire 100 to the second wire 101. Further, after the rear wheel of the vehicle leaves the first wire 100, the car washing system may issue a command to decrease the rotation speed of the second driving motor 130 of the second wire 101. This makes it possible to achieve a sufficient cleaning of the vehicle in the region of the vehicle washing device.

In step S12, the car wash system continues the operation of the second wire 101 so that the front wheels of the vehicle are transferred to the third wire 102. Here, the second wire body 101 may be in an operating state after receiving a work order. Thereby, the efficiency of the car washing can be improved, and the frequency of the start and stop of the second driving motor 130 can be reduced.

In step S13, after the front wheels of the vehicle are transferred to the third line 102, the vehicle washing system issues an instruction that the vehicle can be started. In order to prevent the influence of the vehicle start on the second transmission chain 127, the car washing system preferably prompts the driver to finish automatic car washing through voice prompt, screen display or the like after the rear wheel of the vehicle leaves the second line 101 and the second line 101 stops operating, so that the vehicle can start the command of the vehicle leaving.

Hereinafter, a vehicle conveying method by a car wash system in which the first line 100 of the conveying apparatus has or does not have active driving power will be described.

The vehicle conveying method according to embodiment 3, comprising the steps of:

s14: after the vehicle stops on the first wire 100 and at least the wheel in front of the vehicle in the incoming direction stops on the second wire 101, the car washing system issues a work order, wherein the first wire 100 can be driven only in the incoming direction of the vehicle, and the second wire 101 is disposed in front of the first wire 100 in the incoming direction of the vehicle and is butted against the first wire 100.

S15: based on the operation command, the second wire 101 is operated so that the vehicle is transferred from the first wire 100 to the second wire 101.

S16: the second wire body 101 continues to operate so that at least the wheel in front of the incoming direction of the vehicle is transferred to the third wire body 102, wherein the third wire body 102 is disposed in front of the second wire body 101 in the incoming direction of the vehicle and is butted against the second wire body 101, and the third wire body 102 can be driven only in the incoming direction of the vehicle.

S17: after at least the wheels in front of the vehicle in the incoming direction are transferred to the third line 102, the vehicle wash system issues a command that the vehicle can be started.

That is, the vehicle conveying method of embodiment 3 is substantially the same as the vehicle conveying method of embodiment 2. The difference is that in embodiment 3, the car washing system issues the operation designation after the wheels of the vehicle stop on the second wire 101. In addition, in the case where the first wire 100 does not have the independent driving power, the car wash system does not issue an operation command to operate the first wire 100 or to make the rotation speed of the first wire 100 and the rotation speed of the second wire 101 the same.
