[0048] In order to better understand the present invention, the following Figures 1 to 12 The technical solution of the present invention is described in detail: when the vertical state of the cylinder body 3 needs to be adjusted, the rear jacking oil cylinder 62 is controlled to be driven through the external control button, and the front jacking oil cylinder 61 is started synchronously. When the rear jacking oil cylinder 62 and the front jacking oil 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 jacking oil cylinder 62 and the front jacking oil cylinder 61 stop running. At this time, the cylinder body 3 is correspondingly in a vertical state, which makes it convenient to lift the cylinder body 3 out for maintenance.

[0049] 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.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting.
