[0023] An adjustable climbing platform precisely controlled in angle by a PLC, comprising a connecting part, an adjusting part and a PLC controller 1.

[0024] Specifically, the connecting part comprises a right-angle support 2, the right-angle support 2 is provided with an inclined table top 3, the right-angle support 2 is fixedly provided with a connecting pin shaft 4, and the connecting pin shaft 4 is fixedly provided with a mounting seat 5.

[0025] Specifically, the adjusting part comprises a rotating support 6 movably sleeved on a pin shaft, one end of the rotating support 6 is provided with a rotating table top 7, a mounting rack 8 is mounted on the lower wall surface of the rotating table top 7, a corner gyroscope 9 is mounted on the lower wall surface of the mounting rack 8, and a hydraulic drive assembly is also mounted on the lower wall surface of the rotating table top 7;

[0026] It should be noted that the hydraulic drive assembly and the mounting rack 8 are fixedly installed on the ground, the right-angle support 2 is supported on the ground, and the vehicle can pass through the inclined table top 3 to connect the gap between the ground and the rotating table top 7, so as to facilitate the vehicle to drive onto the rotating table top 7;

[0027] When the device is used, an operator inputs a target angle value between the rotating table top 7 and the ground on the screen of the PLC controller 1, and then the target angle value is transmitted to the corner gyroscope 9. After the PLC controller 1 receives the target angle value, the difference between the current angle value and the target angle value is calculated, and the hydraulic drive assembly is controlled to work according to the difference. The hydraulic drive assembly drives the rotating table top 7 to rotate until the corner gyroscope 9 detects that the angle of the rotating table top 7 reaches the target angle value. When the angle value of the rotating table top 7 changes during the test process, in order to maintain the accuracy of the angle value, the corner gyroscope 9 continuously monitors the current angle value and feeds back the change to the PLC controller 1. Once the PLC detects that the angle value deviates from the target value, the PLC controller 1 adjusts the hydraulic drive assembly to work to correct the deviation, until the angle value of the rotating table top 7 reaches the target value again, so as to ensure the accuracy and repeatability of the test, and ensure the objective evaluation of the automobile climbing performance;

[0031] It should be noted that the bottom end auxiliary hinge 22 is fixedly installed on the ground. When the hydraulic cylinder 13 is extended or retracted, the rotating table 7 rotates, and at this time, the rotating table 7 drives the top end auxiliary hinge 17 to move, the moving rod 19 moves in the sleeve 20, the moving rod 19 rotates on the top end auxiliary pin 18, the sleeve 20 rotates on the bottom end auxiliary pin 21, and the moving rod 19 and the sleeve 20 are used to protect the extension end of the hydraulic cylinder 13, so as to ensure the stability and balance of the hydraulic cylinder 13, and help to prevent the extension end of the hydraulic cylinder 13 from shaking or tilting.
