The first connecting body is installed at the upper end of the first connecting seat and the upper end of the second connecting seat and provided with the slidable upper lifting seat. Both the front portion and the rear portion of the first connecting body are provided with the installation seats. The rotary adjustable screw is arranged on the installation seats. Compared with the prior art, the improved installation device can be used conveniently, manpower is saved, the installation efficiency is high, and adjustment is convenient and fast.
Description
【Technical field】 [0001] The invention relates to the technical field of shipbuilding, in particular to the technical field of an improved installation device for hydraulic nuts of ship stern shafts. 【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 ...
