[0031] Figure 1-5 The AGV collaborative transport vehicle shown includes an AGV transport vehicle body 1. A limit fixing device 2 is provided on one side of the AGV transport vehicle body 1. The limit fixing device 2 can use two first limit plates 24 and two second limit plates 26 to limit and fix the objects placed on the AGV transport vehicle body 1 in front, behind, left and right, so as to prevent them from tipping over or slipping during the transport process.
[0032] Figure 1-5The limiting and fixing device 2 shown includes a threaded rod 22, a groove 21 is provided on one side of the AGV transport vehicle body 1, one end of the threaded rod 22 is installed through and mounted on one side of the inner wall of the groove 21, and the threads at both ends of the threaded rod 22 are in opposite directions; a motor 23, one side of the motor 23 is fixedly mounted on one side of the AGV transport vehicle body 1, and the output end is fixedly mounted on one side of the threaded rod 22 by means of a coupling; and two first limiting plates 24, one end of each of the two first limiting plates 24 is slidably mounted on the groove 21. The inner wall is threadedly connected to the outer surfaces of both ends of the threaded rod 22; four second limiting plates 26, one end of which is slidably installed in the inner wall of the first limiting plate 24; four springs 25, the two ends of which are fixedly installed on one side of the second limiting plate 26 and one side of the inner wall of the first limiting plate 24; and an auxiliary mechanism 27, which is disposed between one side of the two first limiting plates 24 and is used to limit and fix the top of the object loaded on the AGV transport vehicle body 1. By setting the limiting and fixing device 2, when using the AGV transport vehicle body 1 to transport objects, the object is placed on top of the AGV transport vehicle body 1. First, the second limiting plate 26 is held and pulled outward from the inner wall of the first limiting plate 24, causing the spring 25 to stretch. Then, the motor 23 is started to drive the threaded rod 22 to rotate, thereby causing the two first limiting plates 24 to move in opposite directions. Several second limiting plates 26 also move in opposite directions until one side of the first limiting plate 24 abuts against the surface of the object. Then, the second limiting plate 26 can be released, and under the reset action of the spring 25, it can limit and fix the other two sides of the object. Then, the top of the object is limited again by the limiting mechanism, thereby limiting and fixing the object placed on the AGV transport vehicle body 1. This prevents the object from tilting or slipping due to bumps or inertia during the transportation process, avoiding damage or loss of the items, improving transportation efficiency, and reducing safety hazards in the working environment.
[0033] Figure 1-5 The auxiliary mechanism 27 shown includes an L-shaped block 271, one side of which is fixedly installed on one side of the first limiting plate 24; and an elastic strap 272, both ends of which are fixedly equipped with hooks 273, one end of which is inserted into the inner wall of the L-shaped block 271. By setting the auxiliary mechanism 27, after the first limiting plate 24 and the second limiting plate 26 limit the object placed on the AGV transport vehicle body 1 in all directions, the two hooks 273 on the elastic strap 272 can be hooked into the inner walls of the L-shaped blocks 271 on the two first limiting plates 24, thereby limiting and fixing the top of the object as well, improving the fixing effect of the limiting and fixing device 2, and making it less likely to slip and fall during transportation.
[0034] Figure 1-5 The limiting and fixing device 2 also includes several anti-slip blocks 29, one side of which is fixedly installed on one side of the second limiting plate 26. The anti-slip blocks 29 are made of rubber. By setting the anti-slip blocks 29, the contact friction on one side of the second limiting block can be increased, making it less likely to slip when limiting and fixing the object, thus making the limiting more secure. The limiting and fixing device 2 also includes a telescopic plate 210, both ends of which are fixedly installed on one side of the first limiting plate 24 and located in the inner wall of the slide groove 21. By setting the telescopic plate 210, the threaded rod 22 between the two first limiting plates 24 can be protected in the inner wall of the slide groove 21, preventing external impurities or parts from the object from falling into the slide groove 21 and causing the threaded rod 22 to get stuck. The limiting and fixing device 2 also includes several support rods 211, one side of which is fixedly installed on one side of the inner wall of the first limiting plate 24, and the other end passes through the inner wall of the spring 25 and is slidably installed in the inner wall of the second limiting plate 26. By setting the support rod 211, the inner wall of the spring 25 and the second limiting plate 26 can be supported and reinforced, making it less prone to damage and shaking during use.
[0035] Figure 1-5 The limiting and fixing device 2 shown also includes a protective mechanism 28, which includes a threaded ring block 281, one side of which is fixedly installed on one side of the AGV transport vehicle body 1; and a protective cover 282, one end of which is spirally sleeved on the outer surface of the threaded ring block 281. The motor 23 is disposed within the inner walls of the threaded ring block 281 and the protective cover 282. By setting up the protective device, after the motor 23 has been maintained, one end of the protective cover 282 can be manually sleeved on the motor 23 and then spirally sleeved on the outer surface of the threaded ring block 281, thus protecting the outer surface of the motor 23 and reducing the risk of scratches during use, thereby extending the service life of the motor 23. A connecting rope 283 is fixedly installed on one side of the protective cover 282, one end of which is fixedly installed on one side of the AGV transport vehicle body 1. By setting the connecting rope 283, the protective cover 282 can be fixed to one side of the AGV transport vehicle body 1, so that it is not easy to lose after it is removed.
[0036] Working Principle: The AGV collaborative transport vehicle body 1 utilizes internally installed LiDAR and vision sensors to perceive and locate its environment. It then ensures safe operation through global path planning and local obstacle avoidance algorithms. When using the AGV transport vehicle body 1 to transport objects, the object is placed on top of the AGV transport vehicle body 1. First, the second limiting plate 26 is grasped and pulled outwards from the inner wall of the first limiting plate 24, causing the spring 25 to stretch. Then, the motor 23 is started, driving the threaded rod 22 to rotate. This causes the two first limiting plates 24 to move in opposite directions, and several second limiting plates 26 also move in opposite directions until the first limiting plate 24 is reached. One side of the object is pressed against the surface of the object, and then the second limiting plate 26 can be released. Under the reset action of the spring 25, the other two sides of the object can be limited and fixed. Then, the two hooks 273 on the elastic strap 272 are hooked into the inner wall of the L-shaped block 271 on the two first limiting plates 24, so that the top of the object can also be limited and fixed, improving the fixing effect of the limiting and fixing device 2. Thus, the object placed on the AGV transport vehicle body 1 can be limited and fixed, so that it is not easy to tilt or slip during the driving and transport process due to bumps or inertia, avoiding damage or loss of items, improving transportation efficiency, and reducing safety hazards in the working environment.
