Description
Technical field
The utility model belongs to cable bearer technical field, and in particular to a kind of subway tunnel inner cable support.
Background technology
The tunnels such as subway are typically built using shield method and formed, sideways in circular arc or the shape of a hoof, in traditional tunnel
Cable bearer made using metal zinc-plating material, production process energy consumption is big, process is more, the cycle is long, and cost is high, and produces
Quality can not ensure.The cable bearer used now in railway tunnel and subway is made of angle steel, wherein, between angle steel
Welding procedure is taken, using needing to re-start preservative treatment after 3-5, otherwise, corrosion-resistant and Wind-Pressure Resistance index can not all be protected
Demonstrate,prove the safe handling of cable.And the cable bearer and cable only one of which contact point being made up of angle steel, when on railway tunnel and ground
In use, the cable being laid in thereon easily slips or produced displacement on the big metope of iron radius of curvature.
Utility model content
The purpose of this utility model is to provide a kind of subway tunnel inner cable support, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of subway tunnel inner cable support, including
Base and expansion link, the bottom of the base are pasted with rubber sheet gasket, and the top two ends of the base are welded with protective plate, institute
The inside both sides for stating base are equipped with mounting hole, and the top of the base is provided with thread groove, and the bottom of the expansion link is provided with outer
Screw thread, the external screw thread of the expansion link bottom is threadedly coupled with thread groove, and the top of the expansion link is provided with tapped through hole, described
Tapped through hole is threaded with stop nut.
It is preferred that, expansion bolt is installed in the mounting hole.
It is preferred that, the surface of the base is sprayed with fluorescence coating.
It is preferred that, the stop nut is symmetrical arranged at least provided with four per two adjacent groups stop nut.
Technique effect of the present utility model and advantage：The subway tunnel inner cable support, the rubber pasted by base bottom
Glue gasket can effectively play a part of damping, it is ensured that the stability of base, and protective plate can play guarantor when vertically-mounted
Protect circuit and play dust-proof effect, the external screw thread that expansion link bottom is provided with is threadedly coupled with thread groove, can be in order to support
Regulation, convenient to install with dismantling, the stop nut in expansion link screw top through hole can effectively ensure that circuit is difficult for drop-off,
The apparatus structure is simple, reasonable in design, installs and convenient disassembly, it is easy to adjust, with short production cycle, cost is low, stability is good, fits
It is wide with scope, be conducive to popularizing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1 base, 2 rubber sheet gaskets, 3 mounting holes, 4 protective plates, 5 thread grooves, 6 external screw threads, 7 expansion links, 8 screw threads lead to
Hole, 9 stop nuts.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
