Description

Chute-type railway groove cable bearer

Technical field this utility model relates to a kind of cable bearer, the chute-type cable especially used in railway groove Support.

Background technology railway cable support is a kind of when laying cable in railway bed or railway tunnel roadbed groove The equipment used.Railway cable is divided into power cable and communication cable.There is the slope of 2% on the base of railway bed groove Degree, is beneficial to draining, and the base of railway tunnel roadbed groove is level.The width of power cable groove is 20 centimetres, height is 31.5 centimetres；The width of communication cable groove is 35 centimetres, and height is 30 centimetres；Electricity Partition wall between power cable trench and communication cable groove is low compared with the side wall on both sides 2 centimetres, it is simple to lay groove lid Plate.Typically require 2～5 cables of laying on cable bearer, and the kind of cable is more, mainly has high pressure to pass through Energising cable, low-voltage cable and communication cable.This just require cable trench support need adapt to high temperature, low temperature, tide temperature, The various environment such as filth, have higher corrosion resistance.The most also there is higher intensity and steadiness, with full The various operations when laying, fix and overhauling of the foot cable.The cable trench support currently used mainly uses plastics Manufacturing, corrosion resistance is poor, and structural strength is also inadequate, is susceptible to when laying, fix and overhauling loosen and become Shape.

Disclosed " combined cable trench " patent of Chinese patent CN101820156A (application number: 201010136657.2), including cell body and support, described cell body there is row's cable to prop up along every limit, slot length direction Frame reserving hole, support takes inset type method to be directly bumped in reserving hole, then at support afterbody cement Support reserving hole part is blocked by mortar.This patent is disadvantageous in that: due to railway power cable The width of groove is the narrowest is 20 centimetres, and support takes inset type method to be directly bumped on cable trough sidewall, at deduction Behind the space that the right and left support occupies, middle working place is narrow and small, and power cable is being laid, fixed and maintenance Time operating difficulties.

Summary of the invention the purpose of this utility model seeks to provide a kind of chute-type railway groove cable bearer so that it is in peace When putting and dismantle convenient, improve steadiness.

In order to achieve the above object, the chute-type railway groove cable bearer that this utility model provides has left side knot Structure, right structure, chute attachment structure, shallow grooves and discharge structure, wherein, described left structure has left vertical Post, little hook and left base, described left column is fixed on left chassis left side and near trenched side-wall；Described little hook Having three, one of them little hook is fixed on left column upper end, and a little hook is fixed in the middle of left column, one Little hook is fixed on left base apical position；Described right structure has right column, big hook and right base, described Right column is fixed on the right side of right base and near groove partition wall；Described big hook has two, and one of them big hook is solid Being scheduled on right column upper end, another big hook is fixed on right base apical position；Described chute attachment structure has rotation Turn nut, fixing bolt, sleeve and slide bar, one end of described fixing bolt is fixed on the left upper portion of right base, Described rotation nut sleeve is contained in the other end of fixing bolt；One end of described sleeve and slide bar is separately fixed at left base Lower right side and right chassis left side bottom, the other end of slide bar inserts in sleeve, and sleeve and slide bar connect left structure And right structure；Described shallow grooves has multiple, and shallow grooves is positioned at left column, right column, left base and has on base, Shallow grooves is front and back's symmetrical structure；Described discharge structure is made up of fillet and osculum, and wherein, described fillet has two Individual, fillet is R30 chamfering, and two fillets lay respectively at lower end on the right of left lower end, the base left side and right base；Described Osculum has multiple, and osculum is positioned at left base and the centre position of right base bottom.When this utility model uses, First slide bar is inserted in sleeve, left structure and right structure are put into groove simultaneously, then rotates nut, will Left structure and right structure push sidewall respectively to and partition wall realizes fixing.

The chute-type railway groove cable bearer that this utility model provides has a significant effect: have left structure, Right structure, chute attachment structure, shallow grooves and discharge structure, simple in construction；Shallow grooves not only meets support knot Structure intensity needs, and saves material；Discharge structure is made up of fillet and osculum, the most beneficially draining, also profit In consolidating arrangement in the case of channel bottom is irregular；First slide bar is inserted in sleeve during use, by the left side Structure and right structure put into groove simultaneously, then rotate nut, left structure and right structure are pushed to respectively Sidewall and partition wall realize fixing, and it is the most convenient to dispose and dismantle, it is adaptable to railway bed or railway tunnel roadbed The groove of middle different size.
