Reinforced glass guide brackets and supports, and installation method

Abstract

Cross section of guide frame made from glass fiber reinforced plastic is in ' 'shape. Cover with cross section in ' 'shape is added on the guide frame. A glass fiber reinforced plastic guide frame for cabling for a ship and a mounting frame thereof are provided. The cross section of the glass fiber reinforced plastic guide frame is a ''U'' shape, and a cover with the cross section of ''n'' shape is added thereon. The frames of the glass fiber reinforced plastic guide frame are an ''E'' type combination frame, a ''Y'' type combination frame, an ''L'' type frame, a ''U'' type bracket, a reverse "<" type bracket or a linear frame. The type of the mounting frame is selected according to the structure of the ship body and the type of the glass fiber reinforced plastic guide frame and the mounting frame is welded on the corresponding position after selection. A cable is arranged in a ''U'' type groove of the glass fiber reinforced plastic guide frame supported on the mounting frame. The glass fiber reinforced plastic guide frame and the mounting frame of the invention play support and protection role for the cable in the ship, have advantages of insulation and anti abrasion or the like, and can save the welding time of the construction on site, improve the construction efficiency, and greatly improve the stability of the welding.

Description

technical field [0001] The invention relates to a liquefied natural gas ship, in particular to a fiberglass guide frame and support for laying ship cables and an installation method thereof. Background technique [0002] During the construction of liquefied natural gas ship (hereinafter referred to as LNG ship), the cable laying is supported by the guide frame, so the guide frame supports and protects the cable. [0003] At present, the conventional cable guide frame used in ship construction is a simple frame welded by punched angle irons. The distance between each group of cable guide angle irons is 250mm, and the distance between different groups of guide frames is about 300mm. The cables are laid directly On the frame, the guide frame used for laying multi-layer cables is a simple frame welded by multi-layer angle iron. [0004] Previously, it was not applied to the FRP guide frame in cable laying, but was directly erected and welded on a simple frame. This method of la...

AI Technical Summary

Problems solved by technology

[0005] ①It cannot effectively protect the cable

Ships traveling on the water are in a state of frequent bumps, which makes the cables on the simple frame wear and tear with the frame especially outdoors for a long time, and there is a safety hazard of rupture due to wear and tear. The damaged cable will have arc discharge. If there is flammable gas, it is easy to dangerous

[0006] ②It is not suitable for the requirements of cables in special environments

The exterior of the ship, especially the explosion-proof area, requires special protection for the cables. The guide frame composed of a simple frame exposes the cables to the outside. Once a fire occurs, the cables, which are important lines of the ship, are easily damaged and cause huge losses to the ship.

[0007] ③The simple frame cannot meet the requirements of large-scale cable laying

The simple frame is not specially designed according to the laying position of the hull cable, and does not have a unified standard structure. The temporary welded frame is not efficient for occasions with large demand during installation, and for some occasions such as curved bulkheads and angled breakpoints Can not play a good role in supporting and protecting the cable
