[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Figure 1-3As shown, the utility model provides an integral lifting mechanism for a cab on a ship, the lifting mechanism comprising a cab lifting cylinder 1, a stainless steel wire rope clamp 2, a wire rope 3, a ball bearing 4, a first guide wheel 5 and a second guide wheel 51. The piston end of the cab lifting cylinder 1 is fixedly connected to the stainless steel wire rope clamp 2 through a connecting piece, one end of the wire rope 3 is fixed to the stainless steel wire rope clamp 2, the wire rope 3 passes around the first guide wheel 5 and the second guide wheel 51, and is fixed to the ball bearing 4 after being guided by the first guide wheel 5 and the second guide wheel 51. Four stainless steel wire rope tensioners 2 and wire ropes 3 are provided, and several ball bearings 4, first guide wheels 5 and second guide wheels 51 are provided. The first guide wheel 5, the second guide wheel 51, the ball bearings 4, the wire ropes 3 and the stainless steel wire rope tensioners 2 are symmetrically distributed. The four wire ropes 3 are distributed around the bottom cab 20. The fixed end of the cab lifting cylinder 1 is fixedly installed in the cabin of the hull 10. The bottom cab 20 is fixed on the deck of the hull 10. The top cab 30 slides on the outer wall of the bottom cab 20. The stainless steel wire rope The rope clamp 2 is used to fix one end of the wire rope 3. When the piston end of the cab lifting cylinder 1 is extended or contracted, the stainless steel wire rope clamp 2 is used to control the retraction and extension of the wire rope 3, thereby realizing the sliding lifting of the ball bearing 4, so that the top cab 30 can slide and lift vertically on the bottom cab 20. It should be noted that when the top cab 30 slides downward on the bottom cab 20, the cab door on the bottom cab 20 is covered. After passing through the height limit of the bridge channel, as the top cab 30 rises and resets, the bottom cab 20 is The cab door of the driving cab 20 is opened normally, the ball bearing 4 is fixedly mounted on the bottom of the top cab 30, and the roller of the ball bearing 4 is in active contact with the outer wall of the bottom cab 20, which is used to guide the top cab 30 and ensure that the top cab 30 slides vertically stably on the bottom cab 20. The first guide wheel 5 is fixedly mounted in the cabin of the hull 10, and the second guide wheel 51 is fixed to the top of the bottom cab 20 by a fixing part, staggered with the top cab 30. The first guide wheel 5 and the second guide wheel 51 are used to guide the wire rope 3.

[0019] Working principle: During the travel of the hull 10, when encountering the height limit of the bridge area channel, the staff starts the cab jacking cylinder 1, and the piston end of the cab jacking cylinder 1 contracts. At this time, the stainless steel wire rope clamp 2 and the wire rope 3 follow the piston end of the cab jacking cylinder 1 and synchronously descend. The wire rope 3 moves toward one end of the second guide wheel 51. Under the influence of the deadweight of the top cab 30, the top cab 30 slides downward on the bottom cab 20. At the same time, the roller of the ball bearing 4 rolls and guides on the outer wall of the bottom cab 20, so that the top of the top cab 30 is lower than the height limit of the bridge area channel, and then the cab jacking cylinder 1 is closed;

[0020] When the hull 10 passes through the height limit of the bridge channel, the cab lifting cylinder 1 is started again to extend the piston end of the cab lifting cylinder 1, and the top cab 30 is controlled to the initial height by pulling one end of the wire rope 3 upward.

[0021] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
