A multifunctional installation device for hydraulic nuts of ship stern shafts

Abstract

The invention discloses a multifunctional mounting device for ship tail shaft hydraulic nuts. The multifunctional mounting device comprises a first connecting seat, a second connecting seat, a first connecting body, a second connecting body, a rotating sleeve, a plurality of fixing mechanisms, an upper lifting bracket, a lower lifting bracket, two mounting bases, an adjusting threaded rod, a motor, a gearbox, a gear, a rack, a support, a rotary disk, a fixing hook, a connecting plate, a plurality of slotted holes, a plurality of first fixing bolts, a plurality of through holes, a plurality of second fixing bolts, a first mounting plate, a shaft body, a sleeve body, a pointer and a datum line. The rotatable rotating sleeve is mounted on the first connecting seat and the second connecting seat. The rack and the fixing mechanisms distributed circumferentially are arranged on the rotating sleeve and located between the first connecting seat and the second connecting seat. The first connecting body is mounted at the upper ends of the first connecting seat and the second connecting seat and provided with the slidable upper lifting bracket. Compared with the prior art, the multifunctional mounting device can be convenient to use, capable of saving manpower, high in mounting efficiency and convenient and fast to adjust.

Description

【Technical field】 [0001] The invention relates to the technical field of shipbuilding, in particular to the technical field of a multifunctional 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,...

AI Technical Summary

Problems solved by technology

Because there is a certain friction between the steel wire and the outer ring of the hydraulic nut after lifting, it is very labor-intensive to turn the hydraulic nut, and it is not very convenient to install and cooperate with the end of the stern shaft, and the work efficiency is not high
