Problems solved by technology

Because there are certain errors in the structural dimensions of the transom and stern ramps of each ship, and the transversal width of the transom door frame is about 20 meters, there is a certain deformation within the span range, these factors will lead to rubber The gap between the stern ramp and the door frame of the stern sealing plate at the groove is not consistent, which will lead to inconsistent compression of the rubber in the sealing groove, which will affect the sealing performance of the stern passage, which will easily cause accidents due to poor sealing during future use.

Embodiment Construction

[0026] The present invention is further described below in conjunction with specific embodiment:

[0027] A method for positioning a stern springboard rubber groove bracket for a large ship stern springboard, comprising the following steps:

[0028] The first step: According to the up, down, left, and right positions of the stern door 1 and the stern ramp 2 relative to the door frame of the stern sealing plate 3 and the compression amount of the rubber 4, hoist the stern door 1 and the stern ramp 2 to the pre-installed position, and use a chain hoist, limiter The stern door 1 and the stern ramp 2 are fixed firmly by the positioning board, and the stern seal hinge eye plate 31 is positioned according to the positions of the stern door hinge eye plate 11 on the stern door 1 and the stern ramp hinge eye plate 21 on the stern ramp 2 respectively. Such as figure 1 After the stern door 1 and the stern ramp 2 are hoisted, the stern seal hinge eye plate 31 is welded, and then the ste...

Abstract

The invention relates to a positioning method for a stern ramp rubber groove bracket used for a stern ramp of a large ship. The slot bracket positioning model draws the stern ramp rubber slot bracket positioning reference line; step 3, installs the stern ramp rubber slot bracket along the stern ramp rubber slot bracket positioning reference line; step 4, installs on the stern ramp rubber slot bracket Rubber groove of the stern springboard; step 5, install the rubber in the rubber groove of the stern springboard. The positioning method of the rubber groove bracket used for the stern ramp of a large ship according to the present invention is used to quickly and accurately locate the rubber groove bracket, thereby shortening the installation period of the stern channel system and ensuring the construction quality; at the same time, the method is simple and easy to operate And there is no additional use cost; in addition, this method is suitable for similar ship types, has strong versatility, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a positioning method for a stern springboard rubber groove bracket used for a large ship stern springboard. Background technique [0002] The stern passage system of a large ship consists of a stern door and a stern springboard, which are used for large hovercraft to enter and exit the dock, and are the key to the entire passage system. Among them, the stern ramp is fixed on the deck of the dock by hinges, and the stern door is hung upside down on the stern seal by hinges. When the stern door and the stern ramp are closed together, the stern door and the stern ramp can be locked into one body through a hydraulic latch. It is located on the rubber of the door frame, thereby closing the stern of the ship, effectively separating the outside of the hull and the dock, and acting as a watertight bulkhead. The design of the stern door and stern ramp is relatively complicated, so ...
