Description

Technical Field

[0001] This utility model relates to the field of AGV power vehicle technology, specifically a heavy-duty AGV power vehicle using hydraulic drive. Background Technology

[0002] Traditional hydraulically driven AGVs have relatively fixed clamping mechanism designs, making it difficult to meet the clamping requirements of large, long cylindrical components. Regarding the hydraulic system, there is room for improvement in the installation method of the hydraulic oil tank. Traditional hydraulically driven AGVs use fixed-speed motors, which are ill-suited to the high torque demands of heavy-load starts. Common threaded hole machining methods may weaken the structural strength of the oil tank and lack flexibility in installation and adjustment. Therefore, a heavy-duty AGV is needed that can efficiently clamp large, long cylindrical components, has a stable hydraulic system, and offers flexible installation. Utility Model Content

[0031] Advantageously, the steering wheel box 16 is provided with a perforation 25, through which the oil pipe between the rotary joint 41 and the hydraulic motor 21 passes. The rotary joint 41 is used to realize the oil pipe connection between the vehicle body 11 and the rotating steering wheel box 16, thus avoiding the oil pipe tangling.

[0034] Advantageously, the hydraulic mechanism includes a hydraulic station 14 installed inside the vehicle body 11, a pump 13 installed on one side of the hydraulic station 14, the hydraulic station 14 and the pump 13 connected by an oil circuit, a proportional valve 12 installed inside the vehicle body 11, the proportional valve 12 connected by an oil circuit to the pump 13, the proportional valve 12 and the rotary joint 41 connected by an oil circuit, the proportional valve 12 is used to adjust the hydraulic oil flow and pressure to realize the speed and torque control of the hydraulic motor 21.

[0037] Advantageously, the connecting assembly includes an inner groove 55 disposed at the end of the clamp 53, in which a first connecting block 56 is snapped in one inner groove 55 and a second connecting block 57 is snapped in the other inner groove 55. A bolt 54 is disposed in the first connecting block 56, and the bolt 54 passes through the first connecting block 56 and then through the second connecting block 57. The bolt 54 and the second connecting block 57 are threadedly connected.

[0038] Advantageously, the gasket assembly includes a first gasket 52 and a second gasket 58 fixedly disposed on the outer surface of the clamp 53.

The columns 32 are symmetrically disposed on opposite sides of the vehicle body 11.

[0040] This heavy-duty AGV power vehicle is used to transport large cylindrical parts. When placed, the inclined plane 33 serves to limit the movement of the parts. Through the hydraulic system consisting of hydraulic station 14, pump 13, proportional valve 12, encoder 24, hydraulic motor 21 and rotary joint 41, the wheels 22 can rotate, thereby enabling the AGV power vehicle to realize the function of carrying and moving goods.

[0041] When the hydraulic system is working, after the pump 13 works, it circulates the hydraulic oil between the hydraulic station 14 and the oil tank 51 to supply oil to the proportional valve 12. After the proportional valve 12 supplies oil, it supplies oil to the rotary joint 41. Since the rotary joint 41 is existing technology, it can supply oil to the hydraulic motor 21 while the steering wheel box 16 is rotating. After the hydraulic motor 21 is supplied with oil, it works to drive the wheel 22 to rotate, so as to realize the function of heavy-duty AGV power vehicle operation.

[0042] For the installation of oil tank 51, the bolt 54 can be rotated to make the bolt 54 and the second connecting block 57 threadedly connected, thereby changing the size distance between the two ends of the clamp 53, so that the clamp 53 can press the oil tank 51 tightly, and the first pad 52 and the second pad 58 can fit tightly between the clamp 53 and the oil tank 51.
