Problems solved by technology

[0004] In order to solve the existing method, the length of the rudder stock is often increased at the end of the rudder stock and press-fitted with a special oversized nut. This method increases the cost of materials, and additional special large wrenches for installing and dismounting the special oversized nut are required. Efficiency is also relatively poor, the invention provides a ship rudder stock installation and disassembly structure and its installation and disassembly method

Embodiment 1

[0038] Please refer to the attached Figure 1-3 , of which, attached Figure 1-3 It shows the installation and disassembly structure of a ship rudder stock provided by the embodiment of the present application, including a rudder stock part 7 and a rudder stock seat 8, and the installation and disassembly structure is used to install the rudder stock part 7 on the rudder stock seat 8 and The rudder stock part 7 is disassembled from the rudder stock seat 8, including the iron bar 1, and the iron bar 1 is detachably connected with the rudder stock part 7 or the rudder stock seat 8 through a screw structure;

[0039] When the iron bar 1 is connected with the rudder stock 7, an interval area 1 is formed between the iron bar 1 and the rudder stock seat 8, and a hydraulic jack 6 is arranged in the interval area 1, and the hydraulic jack 6 can increase the interval of the interval area 1 ;

[0040] When the iron bar 1 is connected with the rudder stock seat 8, an interval area 2 is...

Embodiment 2

[0047] A method for installing a ship's rudder stock, the method adopts the installation and disassembly structure of the ship's rudder stock in embodiment one, comprising the following steps:

[0048] S1. Thread the bottom end of the middle screw 2 to the rudder stock 7, and then thread the first middle nut 4 on the middle screw 2, so that the bottom end of the middle nut 4 is on the top of the rudder stock 7;

[0049] S2, pass the top of the middle screw rod 2 through the middle through hole 12 of the iron bar 1, and then thread the second middle nut 4 on the middle screw rod 2, so that the bottom end of the second middle nut 4 is against the bottom of the iron bar 1 top;

[0050] S3. Place a hydraulic jack 6 in the area formed by the iron bar 1 and the rudder stock seat 8, control the extension of the hydraulic jack 6, and push the rudder stock member 7 to move relative to the rudder stock seat 8.

Embodiment 3

[0052] A dismounting method of a ship's rudder stock, the method adopts the installation and disassembly structure of the ship's rudder stock in embodiment one, comprising the following steps:

[0053] S1. Thread the bottom end of the side screw 3 to the rudder stock seat 8, and then thread two side nuts 5 on the side screw 3, so that the bottom end of one of the side nuts 5 rests on the top of the rudder stock seat 8 ;

[0054] S2, pass the top of the side screw 3 through the side through hole 13 of the iron bar 1, then thread the third side nut 5 on the side screw 3, so that the bottom of the third middle nut 4 is pushed against the bottom of the iron bar 1 top;

[0055]S3. Place a hydraulic jack 6 in the area formed by the iron bar 1 and the rudder stock member 7, and control the extension of the hydraulic jack 6 to make the rudder stock member 7 move relative to the rudder stock seat 8.

Abstract

The invention provides a mounting and dismounting structure of a ship rudderstock and mounting and dismounting methods of the ship rudderstock. The mounting and dismounting structure comprises a rudderstock piece and a rudderstock bearing; the mounting and dismounting structure is used for mounting the rudderstock piece on the rudderstock bearing and dismounting the rudderstock piece from the rudderstock bearing and comprises an iron bar, and the iron bar is detachably connected with the rudderstock piece or the rudderstock bearing through a screw structure; when the iron bar is connected with the rudderstock piece, a first interval area is formed between the iron bar and the rudderstock bearing, a hydraulic jack is arranged in the first interval area, and the interval of the first interval area can be increased through the hydraulic jack; when the iron bar is connected with the rudderstock bearing, a second interval area is formed between the iron bar and the rudderstock piece, the hydraulic jack is arranged in the second interval area, and the interval of the second interval area can be increased through the hydraulic jack. The invention belongs to the technical field of mounting of ship rudderstocks. Through combination of bar iron, screws, nuts and the jack, on the basis that the length of a rudderstock body is not increased, the rudderstock can be easily and conveniently press-fitted and disassembled.

Description

technical field [0001] The invention relates to the technical field of installation of a ship rudder stock, in particular to a ship rudder stock installation and disassembly structure and an installation and disassembly method thereof. Background technique [0002] The ship rudder stock and the rudder stock seat achieve the function of torque transmission through the friction force connected by the conical surface. Large positive pressure to achieve the effect of increasing friction. [0003] The existing methods mostly use increasing the length of the rudder stock at the end of the rudder stock and press-fitting it with a special oversized nut. This method increases the cost of materials, and additional special large wrenches are required for installation and disassembly of the special oversized nut. , so the installation efficiency is also poor. Contents of the invention [0004] In order to solve the existing method, the length of the rudder stock is often increased a...
