Description
Technical field
This utility model relates to a kind of modular power cable tunnel camber support.
Background technology
At present, in various tunnels power cable is laid, cable bearer is the most extensively applied.Conventional cable bearer includes the cable bearer etc. that steel, composite make, aluminium alloy makes.Steel cable bearer is due to from great, add the labor intensity of installer, simultaneously, although can have certain antiseptic effect after surface processes, but compared with other materials, its service life is relatively low, have because of electromagnetic induction, this support can not make the full circle of closing, this should add installation difficulty and decrease support intensity.The cable bearer that composite makes, structure is complicated, and comprehensive strength is low, and installation difficulty is high, is difficult to the special environment bearing in tunnel.Cast aluminium alloy gold circular arc support, although overcome above-mentioned steel and the cable bearer shortcoming of composite making, but this product structure is complicated, precision is low, control of product quality difficulty, and interchangeablity is poor, Heavy Weight, the shortcomings such as installer's labor intensity is big, and price is high.
Utility model content
This utility model pin purpose is to provide a kind of modular power cable tunnel camber support.
In order to solve above-mentioned technical problem, a kind of technical scheme of the present utility model is: a kind of modular power cable tunnel camber support, including camber stake body, camber stake body is made up of the first arc frame being sequentially connected with, the second arc frame, the 3rd arc frame, first arc frame upper end is connected with second arc frame one end, the second arc frame other end and the 3rd arc frame upper end are connected, first arc frame lower end is connected through a pair of spiral expansion mechanism and the 3rd arc frame lower end, and the first arc frame and the 3rd arc frame are respectively and fixedly provided with some cross-arms.
Further, the first arc frame, the second arc frame, the 3rd arc frame all offer some connecting holes for installing cross-arm.
Further, cross-arm is provided with wire clamp or cable testing bridge.
Further, the first arc frame, the second arc frame, the 3rd arc frame, cross-arm all use 6063 aluminium alloys to make.
Further, cross-arm inner hollow.
Further, the first arc frame upper end is connected through being connected sheet with second arc frame one end, and the second arc frame other end and the 3rd arc frame upper end are connected through connecting sheet.
Further, Double helix expansion mechanism includes that twin screw, two, twin screw two ends expansion sleeve are connected with the first arc frame and the 3rd arc frame respectively.
Compared with prior art, this utility model has the advantages that employing fine aluminum alloy makes, and improves corrosion resistance, add bearing capacity, use three-chip type arc structure, alleviate weight, reduce cost, use Double helix expansion mechanism, optimize swelling method, adding reliability, simple in construction, installation is convenient, low cost, intensity is high, uses safety, sturdy and durable, it is adaptable to the excellent facility of cable is laid in power system in tunnel.
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
