In the related art, the transportation and storage of large-scale objects such as PC prefabricated parts for buildings have the technical problems of high cost and low efficiency. In view of this, the present embodiment provides a modular primary-secondary vehicle, which can achieve automatic intelligent storage and transportation of objects such as prefabricated components for buildings, can improve operation efficiency and reduce labor cost, and can be freely combined to adapt to components of different sizes based on the modular design, so as to effectively improve the adaptability thereof and further reduce cost. The modular primary-secondary vehicle structure will be described in detail below.

Fig. 1 is a schematic structural diagram of a modular primary-secondary vehicle 100 provided in this embodiment; fig. 2 is a schematic structural diagram of a head 103 of the frame 101 provided in this embodiment; fig. 3 is a schematic structural diagram of the child-mother vehicle unit 105 provided in this embodiment; fig. 4 is a schematic structural diagram of the parent vehicle unit 115 provided in this embodiment; fig. 5 is a schematic structural diagram of the sub-cart unit 117 provided in this embodiment. Referring to fig. 1 to 5, the modular primary-secondary vehicle 100 provided in this embodiment is mainly used for storing and transporting PC prefabricated parts for construction. Of course, in other embodiments, it may also be used to carry other articles, and the description of this embodiment is omitted. Meanwhile, in the present embodiment, the modular primary-secondary vehicle 100 specifically includes a frame 101 and a primary-secondary vehicle unit 105.

In detail, the frame 101 is a main structure of the whole modularized primary-secondary vehicle 100, and can provide guarantee for the operation and working of the modularized primary-secondary vehicle 100. The primary and secondary vehicle units 105 are disposed above the frame 101, and the primary and secondary vehicle units 105 include a primary vehicle unit 115 and a secondary vehicle unit 117. The sub-cart unit 117 is disposed on the main cart unit 115, the main cart unit 115 is used for carrying the sub-cart unit 117 to move synchronously along a first direction, and the sub-cart unit 117 can separate from the main cart unit 115 to move alone along a second direction. Wherein, the second direction and the first direction form an included angle. When the component needs to be transported, the whole main vehicle unit 115 can drive the sub vehicle unit 117 to move synchronously, and then the sub vehicle unit 117 moves to the position where the component needs to be transported to carry out the transporting operation. Meanwhile, the sub-cart unit 117 is provided with a lifting mechanism 123, and the lifting mechanism 123 is used for taking and placing the goods after the sub-cart unit 117 moves to the destination, so that after the sub-cart unit 117 is separated from the main cart unit 115 and moves to the destination to be carried, the taking and placing of the components can be completed only through the movement of the lifting mechanism 123.

In more detail, with this arrangement, when it is desired to convey the components from the a stack to the a stack for the articles of the B stack, the parent car unit 115 may carry the child car unit 117 from the a stack and move first in the first direction, and when the parent car unit 115 moves to be spaced from B in the second direction, the child car unit 117 may be activated to move alone and move alone in the second direction toward the B stack. When the child cart unit 117 moves to the B-stack, it can pick up the components from the B-stack by movement of its lifting mechanism 123, and then move in a second direction with the components to return to the parent cart unit 115. Then, the primary cart unit 115 carries the secondary cart unit 117 and the component to return to the a stack together, and the component is placed on the a stack by using the lifting mechanism 123.

That is, with the above arrangement, on one hand, the parent car unit 115 and the child car unit 117 of the modularized child-parent car 100 both move linearly, which does not need to be driven by a complicated driving mechanism, and thus the cost can be saved; meanwhile, the matching of the sub-vehicle unit 117 and the main vehicle unit 115 can realize that the main vehicle unit 115 drives the sub-vehicle unit 117 to move along a first direction, and simultaneously, the sub-vehicle unit 117 can move to a destination along a second direction away from the main vehicle unit 115 to carry out carrying operation, so that the automatic intelligent storage and carrying of objects such as prefabricated parts for buildings and the like can be realized, the working efficiency can be improved, and the labor cost can be reduced; on the other hand, because the sub-cart unit 117 and the main cart unit 115 are both of a modular design, the modular sub-and-main cart 100 can be freely combined to adapt to different sizes of components, for example, when the size or weight of the component to be handled is large, the sub-cart unit 117 with larger carrying capacity and size can be replaced, and even the main cart unit 115 matched with the sub-cart unit can be replaced at the same time to realize the handling operation of the component, so that the adaptability can be effectively improved, and the cost can be further reduced.

Meanwhile, a first rolling member is disposed below the first supporting member 133, the first rolling member may be a roller, and the first driving mechanism 121 is disposed on a side wall of the first supporting member 133, and is in transmission connection with the first rolling member, and is configured to drive the first rolling member to roll along a first direction, so that the first chassis 119 can move along the first direction. That is, by the arrangement of the first chassis 119 and the first driving mechanism 121, the entire parent vehicle unit 115 can drive the child vehicle unit 117 to move in the first direction, so as to ensure the orderly carrying operation of the components.

Of course, in other embodiments, under the condition that the cost allows, the number of the first driving mechanism 121 and the first rolling members may be increased or decreased according to the requirement, so as to ensure the stability and the safety of the movement process of the primary and secondary vehicle units 105, and thus the efficiency of the carrying work may be ensured, which is not limited in this embodiment.

It should be noted that, in the present embodiment, the frame 101 is further provided with a head 103, and the head 103 can be used to control the carrying operation of the whole component. The locomotive 103 comprises an electric control cabinet 107 and a first cable drum 109, a first cable is wound on the first cable drum 109, the electric control cabinet 107 is electrically connected with one end of the first cable, and the other end of the first cable is electrically connected with a first driving mechanism 121.

Referring to fig. 4 again, in order to ensure the stability of the secondary vehicle unit 117 supported above the primary vehicle unit 115, two rails 129 are further disposed on the first chassis 119 of the primary vehicle unit 115, the two rails 129 are respectively disposed on two sides of the first chassis 119 and are adapted to the second rolling members, so that the four second rolling members disposed on one side of the second chassis 125 can be matched with one rail 129, and the four second rolling members disposed on the other side of the second chassis 125 are matched with the other rail 129, thereby sufficiently ensuring the stability and reliability of the secondary vehicle unit 117, and simultaneously facilitating the secondary vehicle unit 117 to smoothly separate from the primary vehicle unit 115 or smoothly match with the primary vehicle unit 115, and further improving the operation efficiency. Of course, in other embodiments, the number of the second rolling members and the number of the second driving mechanism 127 may be increased or decreased according to the requirement, and the efficiency and stability of the carrying operation may be ensured, which is not limited in this embodiment.

Of course, in other embodiments, an elongated slot may be formed on the second supporting member 135 of the first chassis 119 to form the rail 129 structure, which is not limited in this embodiment.

Referring to fig. 3 to fig. 5 again, in the present embodiment, the lifting mechanism 123 is specifically disposed on a side of the second chassis 125 away from the second rolling element. The second driving mechanism 127 is disposed on the second chassis 125, and is in transmission connection with the second rolling element, for driving the second rolling element to roll along the second direction, so that the second chassis 125 can move along the second direction.

The first fitting member 143 and the second fitting member 145 are respectively used for fixedly connecting or hinging with the mother vehicle unit 115 at the corresponding positions thereof, so as to realize the modular integration of a plurality of mother and daughter vehicle units 105, thereby ensuring the working efficiency.

Certainly, in other embodiments, the modular primary-secondary vehicle 100 may further include a plurality of primary-secondary vehicle units 105, for example, three, four, etc., according to requirements, and at least one unit link 137 is connected between two primary vehicle units 115 of any two adjacent primary-secondary vehicle units 105, so as to meet various storage and transportation requirements, which is not limited in this embodiment.

Fig. 8 shows another way of matching the two mother vehicle units 115 according to the present embodiment; fig. 9 is a schematic structural diagram of the connection bracket 151 according to this embodiment. Referring to fig. 8 and 9, in this embodiment, in order to realize any combination of the primary and secondary vehicles with any length, when the number of the primary and secondary vehicle units 105 is multiple, one or more connecting brackets 151 may be connected between two primary vehicle units 115 of any two adjacent primary and secondary vehicle units 105.

In detail, referring to fig. 8 again, the number of the primary and secondary vehicle units 105 may be three, wherein a connecting bracket 151 is disposed between two primary and secondary vehicle units 105, and three connecting brackets 151 connected side by side may be disposed between two adjacent primary and secondary vehicle units 105, and this embodiment is mainly described with one connecting bracket 151.

In more detail, the connection bracket 151 includes a bracket body 153 and first and second links 155 and 157 disposed at first and second sides of the bracket body 153, the bracket body 153 is disposed in a substantially plate-shaped structure, and the number of the first and second links 155 and 157 is one or more and is fixedly connected to the bracket body 153. Meanwhile, the first link 155, the second link 157, the first mating member 143, and the second mating member 145 are similar in structure, and the first link 155 is connected to one of the adjacent two mother vehicle units 115, and the second link 157 is connected to the other of the adjacent two mother vehicle units 115. The primary and secondary vehicles can be freely combined in any length by the connecting bracket 151 to meet different operation requirements, so that the operation efficiency and reliability can be further improved, and the adaptability of the whole modularized primary and secondary vehicle 100 is ensured.

The following describes in detail the installation process, operation principle and beneficial effects of the modular primary-secondary vehicle 100 according to the embodiment of the present invention:

when the modularized primary-secondary vehicle 100 is installed, the electric control cabinet 107 and the first cable drum 109 can be firstly arranged on the frame 101, and then the second rolling piece of the primary vehicle unit 117 and the track 129 of the secondary vehicle unit 115 are assembled into the primary-secondary vehicle unit 105; next, one or more primary and secondary vehicle units 105 are placed on the frame 101, and when the number of the primary and secondary vehicle units 105 is multiple, the primary vehicle units 115 of two adjacent primary and secondary vehicle units 105 are connected and matched through the unit link 137 or the connecting bracket 151; finally, the first cable drum 109 is electrically connected to the first driving mechanism 121, and the second cable drum 111 is electrically connected to the second driving mechanism 127.

When the modular primary and secondary vehicles 100 carry out the component conveying operation and when the component needs to be started from the A stack to obtain the component of the B stack: the primary cart unit 115 can be controlled by implementing a set program to carry the secondary cart unit 117 to start from the A stack and move along the first direction, and when the primary cart unit 115 moves to be spaced from the B stack in the second direction, the secondary cart unit 117 is continuously controlled to start and move independently to move towards the B stack in the second direction. When the child car unit 117 moves to the B-stack, it can drive the lifting frame 124 to take the component from the B-stack by its drive assembly, and then move in the second direction with the component to return to the parent car unit 115 to complete the pick-up.

When the component obtained from the B stack needs to be transported to the a stack, the primary cart unit 115 can be controlled by implementing a set program to carry the secondary cart unit 117 to start from the B stack and move along the first direction, and when the primary cart unit 115 moves to be spaced from the a in the second direction, the secondary cart unit 117 is continuously controlled to start and move independently to move towards the a stack along the second direction. When the sub-cart unit 117 moves to the a-stack, it may drive the lifting frame 124 via its drive assembly to place the component on the a-stack to complete the put.

In the above process, on one hand, the modularized primary-secondary vehicle 100 can realize the automatic intelligent storage and transportation of the objects such as the prefabricated parts for the building through the matching of the primary vehicle unit 115 and the secondary vehicle unit 117, so that the working efficiency can be improved, and the labor cost can be reduced; on the other hand, since the sub-cart unit 117 and the main cart unit 115 are both in a modular design, the modular sub-cart 100 can be freely combined to adapt to members with different sizes, so that the adaptability can be effectively improved, and the cost can be further reduced.

In summary, the embodiments of the present invention provide a modular primary-secondary vehicle 100 with low cost and high efficiency, which can implement automatic intelligent storage and transportation of objects such as prefabricated components for building, and can be freely combined to adapt to components with different sizes based on its modular design, thereby effectively improving its adaptability.
