When the rear lifting cylinder 62 and the front lifting cylinder 61 drive the casing 2 to adjust the tilt angle, the synchronous cylinder body 3 is offset, and the moving distance and movement direction of the cylinder body are judged by the pull-wire sensor, and the casing 2 is monitored by the inclination sensor to see whether it is in a horizontal state. When the inclination sensor detects that the casing 2 is in a horizontal state, the rear lifting cylinder 62 and the front lifting cylinder 61 stop running, and the cylinder body 3 is in a vertical state, which makes it convenient to lift the cylinder body 3 out for maintenance. When the tilt angle of the cylinder body 3 needs to be adjusted, the rear lifting cylinder 62 and the front lifting cylinder 61 are controlled to operate through the external control button, and the casing 2 is pushed to tilt to the left. The movement direction is determined by the pull-wire sensor, and the tilt sensor is used to monitor whether the casing 2 is in a tilted state. When the tilt angle reaches 20°, the tilt sensor transmits data to the signal processor, and the control system controls the front lifting cylinder 61 and the rear lifting cylinder 62 to stop driving, so that the cylinder body 3 is in a tilted state. After the cylinder body 3 completes the posture adjustment, the limit sensor is used to confirm whether the cylinder body has reached the final position. After ensuring safety, the anti-dumping end 8 is locked, which can effectively improve the stability of the cylinder body 3 during posture adjustment, improve the safety during operation, and protect the cylinder body 3 at the same time.
