Embodiment

[0028] Referring to the attached Figures 1 to 4 , a double-hook traction type AGV includes an AGV vehicle 1 and a material vehicle 2. There are two traction hooks 3 provided on the AGV vehicle 1, and two traction plates 4 are provided on the material vehicle 2. The traction hook 3 includes a connecting column 34. A traction groove is formed on the traction plate 4. Each traction hook 3 is connected to one traction plate 4, and the connecting column 34 is arranged in the traction groove. The traction groove includes a first traction groove 42 and a third traction groove 44. The first traction groove 42 is composed of a V-shaped groove and a rectangular groove that are connected and communicated. The width of the third traction groove 44 is the same as the diameter of the connecting column 34.

[0029] A hopper for placing materials is provided on the material vehicle 2. Two universal wheels 21 and two supporting wheels 22 are arranged at the bottom of the material vehicle 2. The two universal wheels 21 are respectively arranged at the front and rear ends of the material vehicle 2, and the two supporting wheels 22 are respectively arranged at the left and right ends of the material vehicle 2.

[0030] A second traction groove 43 is further arranged between the first traction groove 42 and the third traction groove 44, and the width of the second traction groove 43 gradually decreases in the direction from the first traction groove 42 to the third traction groove 44.

[0031] The traction hook 3 includes a connected mounting plate 31 and a connecting plate 32. The connecting column 34 is vertically fixed on the mounting plate 31. A connecting hole 33 is formed on the connecting plate 32. A threaded hole is formed on the AGV vehicle 1. The connecting plate 32 is fixed on the AGV vehicle 1 through the connecting hole 33, a bolt, and the threaded hole.

[0032] The towing plate 4 includes a plate body 41. The first towing groove 42, the third towing groove 44 and the second towing groove 43 are integrally formed on the plate body 41. Both plate bodies 41 are fixed on a connecting block 45, and the connecting block 45 is fixed on the material truck 2.

[0033] Working principle: The material truck 2 is the object that the AGV vehicle 1 is responsible for towing and moving, and it can load various materials. The towing hook 3 is used to connect with the towing plate 4 on the material truck 2, so as to realize the towing and control of the material truck. The connecting column 34 is the core part of the towing hook 3. It can move in the towing groove on the towing plate 4 to realize the connection and separation from the material truck. The towing plate 4 is arranged on the material truck 2 and is the bearing component of the towing hook 3. The towing grooves formed on the towing plate 4 are designed with specific shapes and sizes to adapt to the connecting column 34 of the towing hook 3 and ensure the reliability of the connection.

[0034] The first towing groove 42 is composed of a V-shaped groove and a rectangular groove that are connected. The setting of the rectangular groove facilitates sleeving the first towing groove 42 on the connecting column 34. The V-shaped groove part helps to guide the connecting column 34 into the correct position, that is, the bottom of the V-shaped groove. At the same time, the setting of the V-shaped groove allows the connecting column 34 to move within a limited range in the groove to adapt to various dynamic changes during the towing process, that is, the changes during turning. The width of the third towing groove 44 is the same as the diameter of the connecting column 34, ensuring that the connecting column 34 can be tightly stuck into the third towing groove 44 during backward movement, ensuring that the connecting column 34 can be tightly embedded in the third towing groove 44 and increasing the stability of the connection.

[0035] The universal wheels 21 are placed at the front and rear ends of the material truck 2. Each universal wheel 21 allows the material truck to move in any direction. This enables the material truck to move flexibly on different ground surfaces. Whether it is moving forward, backward, left or right, it can be easily controlled. The flexibility of the universal wheels 21 is crucial for material transfer in a warehouse or on a production line. The support wheels 22 are arranged at the left and right ends of the material truck 2. Each support wheel 22 mainly plays a supporting role to ensure the stability of the material truck when it is stationary or moving on an uneven ground surface. The presence of the support wheels 22 reduces the friction between the universal wheels 21 and the ground, and at the same time increases the contact area of the material truck 2 with the ground, thereby improving the smoothness and safety of driving.

[0036] During the process of the second towing groove 43 from the starting end (the first towing groove 42) to the ending end (the third towing groove 44), the width of the groove gradually decreases. The second towing groove 43 serves as a guiding function and can help the connecting column 34 transition more smoothly from one groove to another groove, ensuring that it does not deviate from the predetermined path.

[0037] The mounting plate 31 is used to carry and fix the connecting plate 32. There are connecting holes 33 on the connecting plate 32, which are used to cooperate with the screw holes on the AGV vehicle 1. By passing bolts through the connecting holes 33, the firm connection between the connecting plate 32 and the AGV vehicle 1 can be ensured.

[0038] Compared with the single-hook connection, the double-hook connection can provide better reverse stability. The two hooks can share the force during reverse together, reducing the shaking and instability of the material vehicle, reducing the risk during reverse. The double-hook connection helps to distribute the load more evenly between the AGV vehicle 1 and the material vehicle 2, which can improve the controllability and stability of the vehicle, especially when carrying heavy goods, reducing the impact of load imbalance on the vehicle performance. Especially during the process of switching between the forward and reverse states, it can prevent the deviation of the direction of the material vehicle.

[0039] Using two towing hooks 3 and two towing plates 4 for connection increases the reliability of the connection. Even if one of the towing hooks 3 has a problem, the other towing hook 3 can still provide a certain connection and support to ensure that the connection between the vehicles will not be easily disconnected.

[0040] The above-described embodiments only represent certain implementation manners of the present utility model. The description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
