example 1

[0021] Example 1: The cable bracket forming an integrated structure with the evacuation platform (see Figure 1 ~ Figure 4 and Figure 7 )

[0022] like image 3 and Figure 7 As shown, the cable support (high-voltage cable support) of this embodiment can be connected and installed integrally with the lower end of the support frame of the circular tunnel evacuation platform b. The evacuation platform is composed of a platform surface 20 and a support frame; the support frame is composed of a crosspiece 21 , a diagonal brace 22 , an upper support 23 and a lower support 9 , or is composed of a crosspiece 21 , a diagonal brace 22 and a carrier 24 . The carrier 24 is a special-shaped component formed by a fireproof polymer composite material, and has an installation hole 25 that can be installed and fixed on the subway tunnel wall. The lower support 9 is a special-shaped part (such as Figure 4 Shown); The mounting hole 10 that can be installed and fixed on the subway tunnel ...

example 2

[0025] Example 2: Weak current cable support for stations (see Figure 5 and Image 6 )

[0026] The cable support in this embodiment is composed of a carrier body 1 and five cross arms 2 integrally formed of a fireproof polymer composite material. The bearing body is straight and long, and the cross section of the bearing body and the cross arm is a H-shaped structure (such as Figure 5 shown in 5-5 and 5-6). A reinforcing rib 3 is provided at the joint between the cross arm and the carrier body. The upper mounting hole 8a and the lower mounting hole 8b of the carrier are located at the upper and lower ends of the carrier respectively, the upper mounting hole is a circular hole, and its upper surface is made into a concave arc surface structure to form a circular arc movable locking structure 11a; The hole is an oblong hole, and its lower surface is made into a convex arc structure to form an arc-shaped movable locking structure 11b.

Abstract

The cable rack of composite polymer material for city rail traffic consists of bearing body and cross arms in I-shaped and / or T-shaped cross section structure. The cross arm or its rib has notches or bosses for easy fixing of cables, and the bearing body has at least two installation holes and may have movable locking structure. The cable rack is made with fireproof composite non-toxic material and has the advantages of insulation, anticorrosion, high strength, convenient installation, easy cable replacing, etc. It is suitable for installation in the wall of different shape tunnels.

Description

technical field [0001] The invention relates to a polymer composite material cable support for urban rail transit. Background technique [0002] Before the present invention was made, cable brackets for urban rail transit were usually made of homogeneous and isotropic metal materials. However, in the subway project, the humid environment of the subway tunnel and the special working conditions of the return flow of the running rail make the metal cable support easy to rust. With the increase of the operation time, this kind of corrosion will continue to worsen, and will eventually become a hidden danger affecting the safety of subway operation. The use of polymer composite materials instead of metal materials to manufacture cable supports can effectively and thoroughly solve the corrosion problem caused by metal supports in tunnels. [0003] When applying composite material cable brackets to semi-enclosed subway tunnels in urban rail transit, polymer composite materials mus...
