[0002] Ship is a general term for various vessels. Ship is a means of transportation that can sail or anchor in waters for transportation or operation, and has different technical performance, equipment and structural types according to different usage requirements. When disassembling and overhauling the main thrust and side thrust blades of a ship, it is generally necessary to use an inspection bracket to move the maintenance personnel to the main thrust and side thrust blades of the ship for maintenance, but the bottom of the existing inspection bracket is always supported by universal wheels, which will cause greater downward pressure damage to the universal wheels, and relying on universal wheels for support will also cause the inspection bracket to be unstable. Therefore, those skilled in the art provide a ship main thrust and side thrust blade disassembly and inspection bracket to solve the problems raised in the above background technology.

The receiving plate moves upward to separate the universal wheel at the bottom of the receiving plate from the ground, and the universal wheel is suspended in the air. The bottom plate is used to support the overall structure. The gravity stabilizing plate on the bottom surface of the bottom plate has the function of maintaining the stability of the overall structure and preventing the overall structure from tilting.

[0015] The push rod is driven to move by the electric push rod assembly, and the movement of the push rod pushes the moving rod to move inside the groove, so that the distance between the maintenance support frame and the support column can be adjusted. The function of the clamping block 1, the clamping block 2 and the limit clamping groove is to prevent the moving rod from falling off from the inside of the groove, which solves the above-mentioned problem. However, the bottom of the existing maintenance bracket always relies on the universal wheel for support, which will cause greater downward pressure damage to the universal wheel. Moreover, relying on the universal wheel for support will also lead to the problem of instability of the maintenance bracket. BRIEF DESCRIPTION OF THE DRAWINGS

The receiving plate 3 moves upward so that the universal wheel 301 at the bottom of the receiving plate 3 is separated from the ground, and the universal wheel 301 is suspended in the air, and the bottom plate 1 is used to support the overall structure. The gravity stabilizing plate 101 on the bottom surface of the bottom plate 1 is used to maintain the stability of the overall structure to prevent the overall structure from being damaged. In case of tilt, the maintenance personnel stand inside the maintenance support frame 9 and use the telescopic cylinder 2 and the telescopic rod 201 to adjust the height of the overall structure. The rotating motor 4 drives the rotating shaft 401 at the upper end of the rotating motor 4 to rotate. The rotation of the rotating shaft 401 drives the support column 5 to rotate. The rotation of the support column 5 drives the support rod 6 to rotate. The rotation of the support rod 6 can adjust the angle of the maintenance support frame 9. The push rod 701 is driven by the electric push rod assembly 7 to move.
