The invention discloses a useable novel mounting device for a ship screw shaft hydraulic nut. The novel mounting device comprises a first connecting base, a second connecting base, a first connecting body, a second connecting body, rotary sleeves, a plurality of fixing mechanisms, an upper hoisting base, a lower hoisting base, two mounting bases, an adjusting screw, a motor, a gear box, a gear, a rack, a concentric positioning mechanism, a shaft body, a sleeve body, a pointer, a datum line and a first mounting plate. The rotary sleeves are rotatably mounted on the first connecting base and the second connecting base. The rack and the fixing mechanisms distributed circumferentially are arranged between the rotary sleeve and the first connecting base as well as between the rotary sleeve and the second connecting base. The first connecting body is mounted at the upper end of the first connecting base and the upper end of the second connecting base. A slidable upper hoisting base is arranged on the first connecting body. The mounting bases are arranged on the front portion and the rear portion of the first connecting body. A rotatable adjusting screw is arranged on the mounting bases. Compared with the prior art, the novel mounting device can be used conveniently, manpower is saved, the mounting efficiency is high, and adjustment is convenient and rapid.
Description
【Technical field】 [0001] The invention relates to the technical field of shipbuilding, in particular to the technical field of an easy-to-use hydraulic nut installation device for a ship stern shaft. 【Background technique】 [0002] With the gradual increase of the tonnage of ships built in our country, the diameter of the hydraulic nut used to lock the propeller on the stern shaft of the ship is also increasing, and its weight has reached more than several hundred kilograms, which cannot be controlled and installed by manpower. The existing installation technology is to enclose the outer ring of the hydraulic nut with a steel cable, and hoist it to the center of the shaft at the outer end of the stern shaft. With the support of the end of the stern shaft, the hydraulic nut is manually tightened on the stern shaft. Because there is a certain friction between the steel wire and the outer ring of the hydraulic nut after lifting, it takes a lot of manpower to turn the hydraulic ...
