Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 , 2 As shown, the third-generation nuclear power plant nuclear island high-seismic cable support of the present invention includes a support arm 2 and a bottom plate 1. The support arm 2 is a W-shaped structure that is buckled upside down, and is formed by rolling a whole plate, and then The upper and lower parts are welded upside down, and the section of the support arm is symmetrical up and down, left and right respectively, with strong stability and high strength. Plates can be made of carbon steel or the like that can meet the strength requirements. The bottom plate 1 and the end of the support arm 2 are connected together by welding. The bent structure increases the contact area, and the length of the weld is longer than that of the old-fashioned bracket, which enhances the strength of the bracket to a certain extent.

Abstract

The invention belongs to a supporting device of a cable bridge of a nuclear power station nuclear island area, and particularly relates to a nuclear power station nuclear island high anti-seismic cable support. The nuclear power station nuclear island high anti-seismic cable support structurally comprises a supporting arm and a baseboard connected with the end portion of the supporting arm, the cross section of the supporting arm is of a two-W-shaped structure, wherein the two W-shaped structures are reversely buckled together, and a plurality of triangular cavities are formed. The nuclear power station nuclear island high anti-seismic cable support can keep being stable under a rated load in an earthquake state, is very small in deformation and has high anti-seismic performance, and due to the fact that no cuspidal edge structures are arranged on the outer portion of the supporting arm and the supporting arm is provided with smooth curved surface structures and plane structures, the nuclear power station nuclear island high anti-seismic cable support is safer on site and the potential hazard of scratching cables is greatly reduced. Two rectangular cavities at the middle of the upper portion and lower portion of the support are symmetrical, the upper side and the lower side of the support can be used for fixation of a bridge, and the nuclear power station nuclear island high anti-seismic cable support is better in universality than an old-type support.

Description

technical field [0001] The invention belongs to a supporting device for a cable bridge in the nuclear island area of ​​a nuclear power plant, and in particular relates to a high-seismic cable support for the nuclear island of a nuclear power plant. Background technique [0002] The cable tray system is an important product in the manufacturing industry, and it is the main equipment used to standardize and protect the safety of cables and transmission lines in various infrastructure projects. The cable bracket is an important part of the cable tray system, and it must have good strength and bending resistance to ensure that it can carry cable trays and cables and other related loads. [0003] The bearing capacity and shock resistance of the cable support are mainly restricted by its support arm structure, material, thickness of the bottom plate and other factors. At present, the traditional old-fashioned cable support arm is welded by C-shaped steel or plate-folding structur...
