Description

Technical Field

[0001] The utility model belongs to the technical field of warehousing logistics, and particularly relates to a connection structure between a traction AGV and a non-controlled material vehicle. Background Art

[0002] In modern warehousing logistics, the logistics warehousing system continuously promotes the development of various industries, followed by the automated logistics system and the automated warehouse. With the development of artificial intelligence technology, AGVs have emerged. AGVs are equipped with lidar, through which maps can be constructed and the positions of obstacles can be obtained. The main function of an automatic traction AGV is to accurately walk and dock at a designated location under computer monitoring according to the path planning and operation requirements to complete a series of operation functions. During the actual walking process, an automatic traction AGV car needs to be docked with a material vehicle through a traction device.

[0003] A bidirectional telescopic automatic decoupling mechanism (CN214112730U) of a traction AGV is disclosed in the prior art. It includes a mechanism base body fixedly installed on the AGV vehicle body; two docking bodies and a driving mechanism are installed on the mechanism base body; the two docking bodies can slide synchronously, isodromically and reversely relative to the mechanism base body; the docking body is provided with a plug-in part; the driving mechanism is used to drive the docking body to move, and the driving mechanism includes a driving motor and a driving gear.

[0004] The above solution realizes the docking and decoupling operations between the AGV and the material vehicle by controlling the synchronous, isodromic and reverse movement of the two docking bodies. However, the above solution requires a driving motor for driving during actual use, and the driving motor needs to be controlled by a controller, which undoubtedly increases the cost and also increases the later maintenance cost. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a connection structure between a traction AGV and a non-controlled material vehicle to solve the problem of high cost caused by the need to use a driving motor to realize the docking and decoupling operations in the prior art.

[0006] To achieve the above object, the technical solution of the present utility model is: a connection structure for a traction type AGV unmanned control material vehicle, including a connection cylinder and a connection component. The connection cylinder is fixed to the AGV vehicle body. One side of the connection component is fixed to the material vehicle, and the other side is used to connect with the connection cylinder. The connection component includes a limit post, a sliding rod, an arc block and a sliding block. The two sides of the limit post are respectively fixed to the material vehicle and the sliding rod. The sliding block is slidably connected to the sliding rod. First arc structures are provided on both sides of the sliding direction of the sliding block. The side of the sliding rod away from the limit post is fixed to the arc block. The side of the arc block away from the sliding rod is set as a second arc structure. The sliding block and the arc block have the same height and are flush on the upper and lower sides. A connection hole for the arc block and the sliding block to pass through is provided on the connection cylinder. A limit hole connected to the connection hole is provided on the connection cylinder. A limit tongue is slidably connected in the limit hole. A third arc structure is provided on the side of the limit tongue away from the bottom of the limit hole. The third arc structure can cooperate with the first arc structure and the second arc structure. An elastic reset member is provided in the limit hole. The elastic reset member is used to reset the limit tongue. Under the elastic force of the elastic reset member, the third arc structure of the limit tongue can extend into the connection hole. The limit tongue can be completely located in the limit hole. The distance between the tops of the sliding block and the arc block after contact is less than the width of the limit tongue.

[0007] Further, multiple groups of the limit holes, limit tongues and elastic reset members are respectively provided.

[0008] Further, a pulling hole is provided on the side of the limit hole away from the connection hole. A pull rod is slidably connected in the pulling hole. One side of the pull rod is connected to the limit tongue, and the other side of the pull rod can extend out of the pulling hole.

[0009] Further, a pull plate is provided on the side of the pull rod away from the limit tongue. The pull plate is located outside the pulling hole and cannot enter the pulling hole.

[0010] Further, a positioning cylinder is provided on the side of the connection cylinder away from the connection component. A hollow chamber communicating with the connection hole is provided in the positioning cylinder. A blocking column is connected to the bottom of the hollow chamber. A blocking plate is connected to one side of the blocking column. The blocking plate is used to limit the displacement of the arc block.

[0011] Further, a guide port is provided on the side of the connection cylinder close to the connection component. The guide port is connected to the connection hole. The guide port is in a conical structure. The small-diameter end of the guide port is connected to the connection hole.

[0012] Further, one side of the limit post close to the slide bar is provided with a conical structure. The small-diameter end of the limit post is connected to the slide bar. The height of the limit post is the same as the height of the sliding block, and the limit post can extend into the connection hole.

[0013] The working principle of this technical solution is as follows:

[0014] When the sliding block is in the initial state, the distance between it and the arc-shaped block is greater than the width of the limit tongue. When it is necessary to connect the AGV vehicle body to the material vehicle, the AGV vehicle body drives the connection cylinder to move towards the connection component. The arc-shaped block and the sliding block can extend into the connection hole inside the connection cylinder, and push the limit tongue towards the bottom of the limit hole, and the elastic resetting member is compressed. When the arc-shaped block moves to one side of the limit tongue, it no longer exerts a pushing force on the limit tongue. Under the elastic force of the elastic resetting member, the limit tongue is driven to reset. At this time, the back surface of the limit tongue blocks the arc-shaped block. When the AGV vehicle body moves forward, the limit tongue pushes the arc-shaped block to move, and then the material vehicle can be pulled to move.

[0015] When towing the goods to the destination, make the AGV vehicle body move towards the connection component again. The limit tongue contacts the first arc-shaped structure on one side of the sliding block. The limit tongue first pushes the sliding block towards the limit post. When the sliding block abuts against the limit post, the limit tongue slides on the surface of the first arc-shaped structure and compresses the elastic resetting member. Then the limit tongue slides to the other side of the sliding block and slides along the surface of the first arc-shaped structure until the arc-shaped block contacts the blocking post. Then make the AGV vehicle body move away from the connection component, so that the limit tongue pushes the sliding block towards the arc-shaped block until the sliding block contacts the arc-shaped block. When the sliding block is in full contact with the arc-shaped block, the limit tongue continues to move. The limit tongue will directly move from the first arc-shaped structure on one side of the sliding block to the second arc-shaped structure of the arc-shaped block, so that the connection component will disengage from the inside of the connection cylinder, realizing automatic hooking and unhooking.

[0016] The beneficial effects of this technical solution are as follows: Through the cooperation among the limit tongue, the sliding block and the arc-shaped plate, this technical solution can realize the automatic hooking and unhooking of the AGV vehicle body and the material vehicle, without using electrical control, reducing costs, and being very convenient for later maintenance.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The embodiment is basically as shown in the attached Figures 1-4 figures: A connecting structure for a traction type AGV unmanned control material cart, used to connect the AGV vehicle body 1 and the material cart 2; specifically includes a connecting cylinder 6 and a connecting component. The connecting cylinder 6 is fixed to the AGV vehicle body 1, one side of the connecting component is fixed to the material cart 2, and the other side is used to connect with the connecting cylinder 6.

[0025] As Figures 1-3 shown, the connecting component includes a limiting post 12, a sliding rod 11, an arc-shaped block 9 and a sliding block 10; both sides of the limiting post 12 are fixed to the material cart 2 and the sliding rod 11 respectively. The sliding block 10 is slidably connected to the sliding rod 11, and first arc-shaped structures 23 are provided on both sides of the sliding direction of the sliding block 10. The side of the sliding rod 11 away from the limiting post 12 is fixed to the arc-shaped block 9, and the side of the arc-shaped block 9 away from the sliding rod 11 is set as a second arc-shaped structure 24. The side of the limiting post 12 close to the sliding rod 11 is set as a conical structure, and the small-diameter end of the limiting post 12 is connected to the sliding rod 11. The limiting post 12, the sliding block 10 and the arc-shaped block 9 have the same height and are flush with each other on the upper and lower sides.

[0026] As Figure 1 、 2, as shown in Fig. 4, the connecting cylinder 6 is provided with a connecting hole 7 for the limit post 12, the arc-shaped block 9 and the sliding block 10 to pass through; the connecting cylinder 6 is provided with a limit hole connected to the connecting hole 7, and a limit tongue 18 is slidably connected in the limit hole. On one side of the limit tongue 18 away from the bottom of the limit hole, there is a third arc-shaped structure 25, and the third arc-shaped structure 25 can cooperate with the first arc-shaped structure 23 and the second arc-shaped structure 24. An elastic reset member 19 (specifically a reset spring) is arranged in the limit hole, and the elastic reset member 19 is used to reset the limit tongue 18. Under the elastic force of the elastic reset member 19, the third arc-shaped structure 25 of the limit tongue 18 can extend into the connecting hole 7; the limit tongue 18 can be completely located in the limit hole. Specifically, there are multiple groups of limit holes, limit tongues 18 and elastic reset members 19 respectively, so as to ensure the stability of the connection. The distance between the end parts of the sliding block 10 and the arc-shaped block 9 in contact is less than the width of the limit tongue 18. When the sliding block 10 contacts the limit post 12, the distance between the sliding block 10 and the arc-shaped block 9 is greater than the width of the limit tongue 18.

[0027] On one side of the limit hole away from the connecting hole 7, there is a pulling hole, and a pull rod 17 is slidably connected in the pulling hole. One side of the pull rod 17 is connected to the limit tongue 18, and the other side of the pull rod 17 can extend out of the pulling hole. On the side of the pull rod 17 away from the limit tongue 18, there is a pull plate 16, and the pull plate 16 is located outside the pulling hole and cannot enter the pulling hole.

[0028] On the side of the connecting cylinder 6 away from the connecting component, there is a positioning cylinder 5. A hollow chamber 20 communicated with the connecting hole 7 is arranged in the positioning cylinder 5. A blocking post 21 is connected to the bottom of the hollow chamber 20, and a blocking plate 22 is connected to one side of the blocking post 21. The blocking plate 22 is used to limit the displacement of the arc-shaped block 9. A positioning plate 4 is fixed on the side of the positioning cylinder 5 away from the connecting cylinder 6, and the positioning plate 4 is fixed to the back plate 3 of the AGV vehicle body 1.

[0029] On the side of the connecting cylinder 6 close to the connecting component, there is a guide port 8. The guide port 8 is communicated with the connecting hole 7. The guide port 8 is in a conical structure, and the small-diameter end of the guide port 8 is connected to the connecting hole 7.

[0030] On the side of the limit post 12 away from the slide bar 11, it is fixed to the base 13, the base 13 is fixed to the mounting plate 14, and the mounting plate 14 is fixed to the fixing plate 15 on the front side of the material cart 2.

[0031] The specific implementation process is as follows:

[0032] When the slider 10 is in the initial state, the distance between the slider 10 and the arc-shaped block 9 is greater than the width of the limit tongue 18. When it is necessary to connect the AGV vehicle body 1 to the material vehicle 2, the AGV vehicle body 1 drives the connecting cylinder 6 to move towards the connecting component. The arc-shaped block 9 and the slider 10 can extend into the connecting hole 7 inside the connecting cylinder 6, and push the limit tongue 18 to move towards the bottom of the limit hole, and the elastic reset member 19 is compressed. When the arc-shaped block 9 moves to one side of the limit tongue 18, it no longer applies a driving force to the limit tongue 18. Under the elastic force of the elastic reset member 19, the limit tongue 18 is driven to reset. At this time, the back surface of the limit tongue 18 blocks the arc-shaped block 9. When the AGV vehicle body 1 moves forward, the limit tongue 18 pushes the arc-shaped block 9 to move, and the material vehicle 2 can be pulled to move.

[0033] When towing the goods to the destination, the AGV vehicle body 1 is moved towards the connecting component again. The limit tongue 18 contacts the first arc-shaped structure 23 on one side of the slider 10. The limit tongue 18 first pushes the slider 10 towards the limit post 12. When the slider 10 abuts against the limit post 12, the limit tongue 18 slides on the surface of the first arc-shaped structure 23 and compresses the elastic reset member 19. Then the limit tongue 18 slides to the other side of the slider 10 and slides along the surface of the first arc-shaped structure 23 until the arc-shaped block 9 contacts the blocking post 21. Then the AGV vehicle body 1 is moved away from the connecting component, so that the limit tongue 18 pushes the slider 10 towards the arc-shaped block 9 until the slider 10 contacts the arc-shaped block 9. When the slider 10 is in full contact with the arc-shaped block 9, the limit tongue 18 continues to move. The limit tongue 18 will directly move from the first arc-shaped structure 23 on one side of the slider 10 to the second arc-shaped structure 24 of the arc-shaped block 9. In this way, the connecting component will disengage from the inside of the connecting cylinder 6, realizing automatic hook-up and unhooking.
