Embodiment Construction

[0020] The installation tool for the rudder stock hydraulic nut on the VLCC of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention cannot be limited by this.

[0021] Please see first image 3 , image 3 It is a structural cross-sectional view of the installation tool for the hydraulic nut of the rudder stock on the ultra-large oil tanker of the present invention. As can be seen from the figure, the installation tool of the rudder stock hydraulic nut on the VLCC of the present invention structurally includes a positioning block 1, a supporting plate 2, a thrust ball bearing 3 and a supporting plate 4 arranged coaxially, and the order from top to bottom is as follows: Block 1, supporting plate 2, thrust ball bearing 3 and support plate 4. It uses the whole device to initially fix the hydraulic nut of the rudder stock, and lifts it to the instal...

Abstract

The invention relates to an installation tool for a rudderstock hydraulic nut of a supertanker, comprising a positioning block, a splint, a thrust ball bearing and a support plate which are coaxially arranged, wherein a positioning plate is an annular structure which corresponds to a bottom structure of the rudderstock hydraulic nut and is fixed with the top of the annular splint through a plurality of bolts; the thrust ball bearing is arranged between the splint and the support plate which are parallel arranged and is fixed with the splint and the support plate through bolts; and the bottom of the support plate is provided with a plurality of screw holes. The tool jacks up the rudderstock hydraulic nut and screws the rudderstock hydraulic nut to a rudderstock by rotating the rudderstock hydraulic nut, and even if the rudderstock hydraulic nut which is hundreds of catties is simple, convenient and flexible to install. The installation tool has simple structure and convenient hanging and transportation and greatly enhances the safety of the installation process of the rudderstock hydraulic nut.

Description

technical field [0001] The invention relates to ship building, in particular to an installation tool required for installing hydraulic nuts of a rudder stock in a rudder system during the construction of super-large oil tankers. Background technique [0002] Very Large Crude Carrier (VLCC) is a trend in the construction of oil tankers, which occupies a very important position in the world's crude oil transportation, and the construction of VLCC is also the goal pursued by various shipbuilding companies. [0003] Due to the huge volume of VLCCs, the corresponding marine parts are also characterized by large volume and heavy weight. During the construction of VLCC ships, the rudder system is also difficult to guarantee accuracy due to its large size and complicated installation process. Especially the hydraulic nut on the rudder stock, the connection relationship between the hydraulic nut and the rudder stock is a threaded connection, and its weight reaches hundreds or even t...
