The conveying device has the advantages that the spool is enabled to be transferred in a rolling mode, the spool is directly contacted and rubbed with the ground, the spool is easy to damage, the spool can be completely lifted off the ground through the lifting mechanism, the requirement on the power configuration of the lifting mechanism is high, the requirements on the strength of the U-shaped part and the connection strength of the U-shaped part and the lifting mechanism are high due to the fact that the two side walls of the U-shaped part are arranged in an overhanging mode, the manufacturing cost is increased, the center of gravity of the U-shaped part is closer to the front in the transferring process, and the whole device has the risk of toppling. In addition, because flexible actuating mechanism level sets up, and sets up in the both sides wall outside of U type spare, lead to whole conveyer's horizontal size great, in the transportation, need sufficient horizontal space of passing through, application scope is restricted, or use very inconveniently in some times.

The clamping and lifting device 100 comprises two clamping arms 101, the two clamping arms 101 are respectively installed on each longitudinal beam 201, the upright column 202 is located at the rear side of the clamping arm 101, and the front end of the clamping arm 101 is provided with an inserting structure for being inserted into a central hole 701 of the spool. As shown in fig. 5, 7 and 9, the front end of the gripping arm 101 is fixedly welded with a connecting plate 117, the inserting structure is specifically an inserting plate 102 fixed on the connecting plate 117, the upper end and the lower end of the inserting plate 102 are respectively provided with an extending plate extending towards the space between the two gripping arms, and the extending plate is an arc-shaped plate and is matched with the hole wall of the central hole 701 of the spool, so that the spool can be stably gripped and transported. Preferably, the insert plate 102 is detachably connected to the connecting plate 117 by bolts, so that another insert plate can be easily replaced to transport spools of different sizes.

The gripping arm 101 is a box-type structure, the longitudinal section of the gripping arm is approximately triangular, and the gripping arm 101 is installed in the middle of the longitudinal beam 201 through a composite installation structure. The composite mounting structure is shown in fig. 10 and comprises a fixed cylinder 109, a vertical rotating shaft 113 and a horizontal rotating shaft 114, wherein the fixed cylinder 109 is inserted and fixed on a longitudinal beam 201, the rotating axis of the vertical rotating shaft 113 extends vertically, the lower part of the vertical rotating shaft 113 is rotatably mounted in the fixed cylinder 109 through a first bearing 115, and the vertical rotating shaft 113 is fixedly connected with a top flange of the fixed cylinder 109 through a mounting plate 116.

The top of the vertical rotating shaft 113 is provided with step surfaces 118 which are arranged in an opposite way, the horizontal rotating shaft 114 penetrates through the top of the vertical rotating shaft 113, and a through hole which is formed in the vertical rotating shaft 113 and through which the horizontal rotating shaft 114 penetrates is communicated with the step surfaces 118 on two sides. Two ends of the horizontal rotating shaft 114 are provided with second bearings 112, two vertical side walls of the gripping arm 101 are respectively fixed with bearing seats 110, the second bearings 112 are positioned in the bearing seats 110, and the horizontal rotating shaft 114 is mutually and rotatably matched with the gripping arm 101 through the second bearings 112. The step surface 118 can facilitate processing of the through hole and installation of the second bearing 112, and the second bearing 112 is closer to the step surface 118, so that the width of the clamping arm 101 can be reduced.

The clamping and lifting device 100 further includes a clamping power mechanism, the clamping power mechanism in this embodiment is a clamping power cylinder 103, the clamping power cylinder 103 is transversely disposed at the rear ends of the two clamping arms 101, the clamping power cylinder 103 includes a main body portion and a telescopic portion, the telescopic portion is connected to the main body portion and can perform linear telescopic motion relative to the main body portion, and the main body portion and the telescopic portion are respectively connected to the rear ends of the two clamping arms 101. Specifically, as shown in fig. 5, 7 and 8, a fixing frame 107 is fixed to the rear end of the gripping arm 101, a fixing rod 108 is provided in the fixing frame 107, a connecting rod 104 is fixed to the outer side surface of the fixing frame 107, and the main body portion and the telescopic portion are respectively hinged to the two connecting rods 104.

The gripping and lifting device 100 further includes two lifting power mechanisms, the lifting power mechanism in this embodiment is a lifting power cylinder 105, and the two lifting power cylinders 105 are respectively vertically disposed at the rear end of each gripping arm 101. The lifting cylinder 105 comprises a fixed part and a movable part, wherein the movable part is connected to the fixed part and can perform linear telescopic motion relative to the fixed part, specifically, the fixed part of the lifting cylinder 105 is arranged above the movable part, as shown in fig. 5 and 7, a fixed plate 106 is arranged at the top of the fixed part, and the fixed part is connected to the upright 202 through the fixed plate 106, as shown in fig. 4. The bottom of the movable part is connected with a fixed rod 108 through a joint bearing.

The gripping arms 101 form a lever structure with the composite mounting structure as a fulcrum, and specifically, as shown in fig. 7 and 8, when the telescopic part of the gripping power cylinder 103 is retracted, the main body part and the telescopic part will pull the gripping arms 101 to rotate in a horizontal plane along the axis of the vertical rotating shaft 113, the two insertion plates 102 move back to back, and the two gripping arms 101 are opened. As shown in fig. 5 and 6, when the telescopic part of the gripping power cylinder 103 is extended, the main body part and the telescopic part push the gripping arms 101 to rotate in the horizontal plane along the axis of the vertical rotating shaft 113, the two insertion plates 102 move toward each other, and the two gripping arms 101 come close together. In the above process, the gripping arm 101 forms a lever structure with the vertical rotation shaft 113 as a fulcrum, and since the movable part of the lifting cylinder 105 is connected to the fixed rod 108 through the joint bearing, the lifting cylinder 105 does not affect the normal swing of the gripping arm.

Referring to fig. 1 and 3, when the two gripping arms 101 are opened, the two longitudinal beams of the spool handling vehicle can move to the two sides of the spool 700, and when the two gripping arms 101 are closed, the insertion plates 102 on the gripping arms are inserted into the central holes 701 of the spool, so that the spool can be gripped.

The lifting power cylinder 105 starts to operate after the clamping power cylinder 103 approaches the two clamping arms 101, that is, the clamping and lifting device operates by clamping and lifting first and then lifting, when lifting, the movable part of the lifting power cylinder 105 extends out, the fixed rod 108 is pressed down, so that the clamping arms 101 rotate in the vertical plane along the axis of the horizontal rotating shaft 114, and as shown in fig. 2 and 9, the front ends of the clamping arms 101 move upwards to separate the spool 700 from the ground, so that the spool can be transported. Otherwise, the spool 700 is lowered. In the process of the up-and-down swinging of the clamping arm 101, a lever structure taking the horizontal rotating shaft 114 as a fulcrum is formed, and the power arm is larger than the resistance arm, and the lever structure is a labor-saving lever, so that the configuration requirements on the lifting power cylinder 105 and the clamping power cylinder 103 can be reduced, and the manufacturing cost is saved.

In the transportation process of the spool 700, in order to avoid the spool 700 from swinging left and right and ensure the stability of the spool, elastic members are respectively connected between the two connecting rods 104 and the frame, the elastic members in this embodiment are springs 111, as shown in fig. 6 and 8, when the clamping and lifting device swings to one side, the spring at the other side is stretched to exert elastic limiting force on the connecting rods to reset the connecting rods, so that the position of the clamping and lifting device can be corrected and kept at the middle position.

The lifting power cylinder 105 and the clamping power cylinder 103 in this embodiment are both electric cylinders, and for convenience of control, a battery pack 400 and an electric control system 300 connected with the electric cylinders are mounted on the frame. For moving conveniently, two fixed wheels 600 and one steering wheel 500 are installed on the chassis of the frame, the two fixed wheels 600 are respectively installed at the bottom of the longitudinal beam, and the steering wheel 500 is installed at the middle of the rear part of the chassis and is connected with the battery pack 400 and the electronic control system 300.

The working principle of the I-shaped wheel loading and unloading transport vehicle is as follows:

when the clamping device is used, the clamping power cylinder 103 controls the two clamping arms 101 to be opened, then the two longitudinal beams of the I-shaped wheel loading and unloading transport vehicle move to the outer sides of the I-shaped wheels 700, and the clamping power cylinder 103 controls the two clamping arms 101 to be closed, so that the inserting plate 102 is inserted into the central holes 701 of the I-shaped wheels, and clamping of the I-shaped wheels is achieved. Then, the lifting power cylinder 105 presses down the clamping arm to lift the front end of the clamping arm 101, so that the spool 700 is lifted off the ground, and the spool can be transported. After the transport to a proper position, the front ends of the clamping arms 101 are controlled to fall, the I-shaped wheels are placed on the ground, then the two clamping arms 101 are controlled to open, and the I-shaped wheel loading and unloading transport vehicle can be moved away.

The spool handling transport vehicle can enable the clamping arm to clamp the spool and realize the transport of the spool lifted off the ground, thereby avoiding the damage to the spool caused by the contact friction between the spool and the ground. Meanwhile, the clamping power cylinder 103 is located at the rear ends of the two clamping arms and arranged between the two clamping arms, and the space outside the clamping arms is not occupied, so that the transverse size of the spool loading and unloading transport vehicle can be relatively small, too large transverse passing space is not needed, and the use is more flexible and convenient. In addition, when the spool handling transport vehicle transports the spool, the whole gravity center is relatively close to the back, the transportation is relatively stable, and the safety is high.
