Abstract
The invention discloses a cable trough support of a railroad bed. The cable trough support is manufactured integrally and provided with supporting columns, a left large hook, a right large hook, a left groove, a middle groove, a right groove, locating holes and locating nails. The left large hook is close to the inner side of the upper portion of the left side wall of a cable trough. The right large hook is close to the inner side of the upper portion of a partition wall of the cable trough. The left groove, the middle groove and the right groove are formed in the bottom in the cable trough support of the railroad bed. Thus, the requirement that a railroad power supply through line is arranged on the upper portion and a low-voltage cable or a control cable is arranged on the lower portion can be met; and when guided out of the cable trough, the low-voltage cable or the control cable does not intersect with the railroad power supply through line, and therefore other cables cannot be influenced or moved during cable laying and maintenance and replacement of one cable, and the cable trough support is suitable for laying of all trough cables.
Description
The field of inventionthe invention relate to a kind of cable bearer, particularly in the cable trench support used in railway bed.
The cable trench of background technology railway bed is generally made up of two parallel U-type groove, is divided into Power Cable Groove and communication cable groove.Specifying according to associated construction specification, the width of power cable groove is 20 centimetres, is highly 31.5 centimetres；The width of communication cable groove is 35 centimetres, is highly 30 centimetres；Consider draining factor, bottom cable trench, have the gradient of spilled water hole, chamfering R30 and 2%.In power cable groove, generally need 1～2 through cable of high pressure of placement and railway power supply through track, 2～3 low-voltage cables or control cable.The external diameter of the through cable of high pressure is generally 6～8 centimetres, and the external diameter of low-voltage cable is generally 1.5～6 centimetres.Partition wall between power cable groove and communication cable groove is lower than 1 centimetre of trenched side-wall top, it is simple to dispose cover plate.This just requires that cable trench support needs to adapt to high temperature, low temperature, the tide various environment such as warm, filthy, has higher corrosion resistance.Also there is higher intensity simultaneously, to meet the cable various operations when laying, fix and overhauling.The cable trench support currently used mainly is adopted and is made of plastic, and corrosion resistance is poor, and structural strength is also inadequate, is easily deformed when laying, fix and overhauling.
" combined cable trench " patent (application number: 201010136657.2) that Chinese patent CN101820156A is disclosed, including cell body and support, described cell body has row's cable bearer reserving hole along every limit, slot length direction, support takes inset type method to be directly bumped in reserving hole, then in support afterbody cement mortar, support reserving hole part is blocked.This patent is disadvantageous in that: support takes inset type method to be directly bumped on cable trough sidewall, behind the space that deduction the right and left support occupies, middle working place is narrow and small, and cable easily loosens in the bracket, and power cable is operating difficulties when laying, fix and overhauling.
Summary of the invention present invention aim to provide a kind of railway bed cable trench support, while increasing corrosion resistance and structural strength so that it is easy to operate when laying, fix and overhauling.
