Mounting tool and mounting method of ship shafting case butt coupling

Abstract

The invention discloses a mounting tool of a ship shafting case butt coupling. The mounting tool comprises a frame body and a derrick assembly, wherein the bottom end of the frame body is vertically and fixedly connected to a shaft body through a first permanent magnetic chuck, a guide rail is arranged on the frame body in the X axis direction, the derrick assembly comprises a base capable of moving along the guide rail back and forth and a derrick fixedly connected to the bottom of the base, and a Y-direction hand wheel for adjusting the derrick to move in the Y-axis direction and a Z-direction hand wheel for adjusting the derrick to move in the Z-axis direction are arranged on the base; and a second permanent magnetic chuck is arranged at the bottom end of the derrick to adsorb the coupling, and a camera device used for shooting the real-time position of the coupling is arranged on the derrick. The invention further provides a mounting method of the ship shafting case butt coupling.According to the mounting tool of the ship shafting case butt coupling, the hoisting safety of the coupling is high, besides, centering during mounting of the coupling is simple and accurate, the labor intensity is reduced, the working efficiency is improved, and the production cost is reduced.

[0002] At present, in the installation process of ship shafting couplings, the hoisting operation is usually carried out manually by using ropes to bind the couplings, manually tying knots, and hanging hoists. However, due to the shape, weight, and The center of gravity is different, especially the parameters such as the precise fit clearance between the coupling and the shaft, as well as the skills and experience of the operators, which affect the binding stability of the coupling, the accuracy of the position of the hanging hoist and the knot of the lifting point performance, the correctness of the attitude of the horizontal alignment of the coupling and hoisting, etc., which in turn affects the safety of the hoisting coupling

Especially for heavy-duty, high-precision couplings, in order to improve the safety of the coupling, it is often necessary to bind multiple times, repeatedly explore the position of the knot at the lifting point, and repeatedly adjust the lifting points of the hoist and pull-in hoist position, which increases the labor intensity of the trial lifting and trial installation process and the alignment accuracy is low
