[0031] Please refer to Figures 1-4 , the present utility model provides a technical solution: a retractable heavy-duty AGV platform, including a first transport platform 1 and a second transport platform 4;

[0032] Two support devices are provided on both the first transport platform 1 and the second transport platform 4;

[0033] The support device includes a support pad 6 and a hydraulic telescopic rod 9. Four mounting blocks 8 are installed on the outer wall of the upper end of the hydraulic telescopic rod 9. The four mounting blocks 8 are fixedly connected to the lower surfaces of the corresponding first transport platform 1 and second transport platform 4 through fixing bolts. The output end of the hydraulic telescopic rod 9 is fixedly connected to a support column 12. A sliding mounting seat groove 17 is opened on the lower surface of the support column 12. One end of the outer wall of the support pad 6 is fixedly connected to a sliding mounting seat 16. The outer wall of the sliding mounting seat 16 is slidably connected to the inside of the sliding mounting seat groove 17. Four pull rod grooves 11 are opened on the outer wall of the lower end of the support column 12. Four pull rods 10 are slidably connected to the inside of the four pull rod grooves 11 respectively. Four first limit block grooves 14 are opened in the inside of the sliding mounting seat groove 17. Four limit blocks 18 are slidably connected to the inside of the four first limit block grooves 14 respectively. The inside of the four pull rod grooves 11 communicates with the inside of the corresponding first limit block grooves 14 respectively. One end of each of the four pull rods 10 close to the limit block 18 slidably extends into the inside of the first limit block groove 14 and is fixedly connected to one end of the corresponding limit block 18 respectively. Four second limit block grooves 15 are opened on the outer wall of the end of the sliding mounting seat 16 away from the support pad 6. One end of each of the four limit blocks 18 close to the second limit block grooves 15 contacts the inner wall of the corresponding second limit block groove 15 respectively. A return spring 13 is sleeved on the outer wall of each of the four pull rods 10. Two ends of the return spring 13 are fixedly connected to the inner wall of the corresponding first limit block groove 14 and one end of the limit block 18 respectively.

[0034] Among them, two telescopic rods 2 are installed at one end of the first transport platform 1, and the ends of the two telescopic rods 2 away from the first transport platform 1 are installed at one end of the second transport platform 4. Two cylinders 3 are installed at the end of the second transport platform 4 close to the first transport platform 1, and the output ends of the two cylinders 3 are fixedly connected to the outer wall of one end of the first transport platform 1. Second auxiliary support wheels 7 are installed on the lower surfaces of both sides of the first transport platform 1, and the same second auxiliary support wheels 7 are installed on the lower surfaces of both sides of the second transport platform 4. First auxiliary support wheels 5 are installed on the lower surface of the first transport platform 1, and the same first auxiliary support wheels 5 are installed on the lower surface of the second transport platform 4.

[0035] Furthermore, when the device is used, it is started by connecting an external power source. First, laser navigation, visual recognition and other technologies are used. The AGV platform perceives the surrounding environment, including landmarks, obstacles, etc., in real time during driving. According to the sensed information, the AGV controller adjusts the driving speed and direction to ensure safe obstacle avoidance and travel along the predetermined path. When the AGV platform reaches the loading area, the output end of the cylinder 3 drives the first transport platform 1 and the second transport platform 4 to adjust the distance according to the size of the goods, so as to automatically adjust the platform size and ensure that the goods can be stably loaded. At the same time, when reloading, the output end of the hydraulic telescopic rod 9 drives the support column 12 to move downward while driving the support pad 6 to move downward, so that the support pad 6 contacts the ground, which increases the stability of the first transport platform 1 and the second transport platform 4. Then, when the AGV platform continues to travel along the planned path, it is transported to the designated position through the cooperation of the first auxiliary support wheel 5 and the second auxiliary support wheel 7. At the same time, the output end of the hydraulic telescopic rod 9 resets and drives the support pad 6 to break contact with the ground. Then, when the support pad 6 needs to be removed, the pull rod 10 is pulled to move in the opposite direction to drive the reset spring 13 to contract and drive the limit block 18 to move in the opposite direction. Then the limit block 18 moves in the opposite direction so that its other end breaks contact with the inside of the second limit block groove 15. Then, the support pad 6 can be removed from the support column 12 by pulling it.

[0036] Automatically adjust the size of the platform through the support device to ensure that the goods can be stably loaded. At the same time, when loading, the output end of the hydraulic telescopic rod 9 drives the support column 12 to move downward and at the same time drives the support pad 6 to move downward, so that the support pad 6 contacts the ground, increasing the stability of the first transport platform 1 and the second transport platform 4. This avoids the AGV platform from being easily toppled by external forces when in a stopped state, improves the stability of the equipment, and further improves the practicality of the equipment. By pulling the pull rod 10 to move in the opposite direction, the return spring 13 contracts and at the same time drives the limit block 18 to move in the opposite direction. Then, when the limit block 18 moves in the opposite direction, the other end of it disengages from the inside of the second limit block groove 15. Then, pulling the support pad 6 can remove it from the support column 12. This facilitates the disassembly of the support pad 6, improves the maintenance and repair efficiency of the support pad 6, and at the same time improves the flexibility of the equipment, making it convenient for the staff to disassemble the support pad 6.

[0037] Working principle: First, using technologies such as laser navigation and visual recognition, the AGV platform perceives the surrounding environment in real time during driving, including landmarks, obstacles, etc. According to the perceived information, the AGV controller adjusts the driving speed and direction to ensure safe obstacle avoidance and travel along the predetermined path. When the AGV platform reaches the loading area, according to the size of the goods, the output end of the cylinder 3 drives the first transport platform 1 and the second transport platform 4 to adjust the distance to complete the automatic adjustment of the platform size, ensuring that the goods can be stably loaded. At the same time, when loading, the output end of the hydraulic telescopic rod 9 drives the support column 12 to move downward and at the same time drives the support pad 6 to move downward, so that the support pad 6 contacts the ground, increasing the stability of the first transport platform 1 and the second transport platform 4. Then, when the AGV platform continues to travel along the planned path, the first auxiliary support wheel 5 and the second auxiliary support wheel 7 cooperate to transport it to the designated position. At the same time, the output end of the hydraulic telescopic rod 9 resets to drive the support pad 6 to disengage from the ground. Then, when it is necessary to disassemble the support pad 6, pulling the pull rod 10 to move in the opposite direction drives the return spring 13 to contract and at the same time drives the limit block 18 to move in the opposite direction. Then, when the limit block 18 moves in the opposite direction, the other end of it disengages from the inside of the second limit block groove 15. Then, pulling the support pad 6 can remove it from the support column 12.

[0038] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
