The invention discloses a novel mounting device of a hydraulic nut of a ship propeller shaft. The novel mounting device comprises a first connecting seat, a second connecting seat, a first connector, a second connector, a rotating sleeve, a plurality of fixed mechanisms, an upper hanging seat, a lower hanging seat, two mounting seats, an adjusting screw, a motor, a gearbox, a gear, a gear rack, a support, a rotating disc, a fixed hook, a connecting plate, a plurality of groove holes, a plurality of first fixed bolts, a plurality of through holes and a plurality of second fixed bolts. The rotatable rotating sleeve is mounted on the first connecting seat and the second connecting seat. The gear rack and the circumferentially-distributed fixed mechanisms are arranged on the part, between the first connecting seat and the second connecting seat, of the rotating sleeve. The first connector is mounted at the upper end of the first connecting seat and the upper end of the second connecting seat and provided with the upper hanging seat capable of sliding. The mounting seats are arranged on the front portion and the rear portion of the first connector and provided with the rotatable adjusting screw. Compared with the prior art, the novel mounting device can be used conveniently, manpower is saved, and mounting efficiency is high.
Description
【Technical field】 [0001] The invention relates to the technical field of ship building, in particular to the technical field of a novel installation device for a ship stern shaft hydraulic nut. 【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 hydraulic nut outer ring after lifting, it takes a lot of manpower to turn the hydraulic nut, and it i...
