Description

A kind of adjustable drop and the power cable applicator of gradient

Technical field

The utility model is related to the power cable applicator of a kind of adjustable drop and gradient, belongs to power industry high-tension electricity Cable applicator device technical field.

Background technology

Power cable is extensively applied in distribution line, when discharging power cable operation, how to accomplish safety, quick, subtract Light construction labour intensity is a key node.In existing cable laid processes, 110kV or 220kV high-tension cables belong to valuable and Again fragile product, often discharges out of doors or under conditions of environment difference, mainly takes lift or the mode that drags during operation, this The top layer insulating barrier of sample cable is easy for sustaining damage or galls, and affects the security performance of cable, and for example city cable is equal at present It is laid in underground piping, when how the main cause that cable broke down after operation a period of time is because laying, cable jacket breaks Damage, moisture, rainwater are entered inside cable, weak in cable（In the middle of cable, terminals）Place hoards, and long-play makes which insulate Reduce and break down, be that this job specfication is strict with to the release of such high-tension cable, on the other hand, due to 110kV and above high-tension cable are making, storage and transport, discharge and run each stage, to the minimum bending radius of cable, past Renaturation bending times etc. have clear stipulaties, and the besides cable hank footpath produced by all kinds of electric pressures, each cable producer is different, applies The factor such as taper into around the cable crimp radius existed on cable hank when putting, during for guaranteeing that cable is discharged, cable hank Gao Yu electricity Bending radius between cable dispensing port is not less than minimum of a value, it is necessary to according to different cable placing height, adaptive adjustment Bogey（Discharge platform）Height and gradient, being beneficial to the telpher being placed on the bogey can be defeated on request Power transmission cable, this are that existing bogey does not adapt to the cable hank height requirement of all kinds of electric pressures, can not ensure cable bend Radius, the main cause for affecting construction quality.Besides existing bogey builds that time-consuming, and structure bulky is transported and torn open Dress is very inconvenient, causes the waste of workmen；Also some simple type bogey steadiness are poor, the yielding damage of construction material The problems such as, remote-effects to cable discharge quality.

Chinese invention patent《Cable applicator and equipment》（201510441209.6）Including：Installing rack, pass through cable The bearing bar of center hole, two axle supports, width adjustable load-bearing support and first driving means, the equipment are only suitable for discharging two Secondary cable or minor diameter cable；Patent of invention《Portable cable rotating releasing frame》（201310328228.9）Only it is that one kind can facilitate Carry and revolution cable turntable device；New patent《High-tension cable aids in wire-unfolding rack》（201220188069.8）Only disclose A kind of cable supporting rolling, without lowering or hoisting gear.
