Description
[technical field]
The utility model relates to Electric Power Line Overhaul device field, in particular to a kind of power transmission lines overhauling rope ladder stretches tight
Straight device.
[background technique]
Rope ladder has flexibility and convenience in terms of tool combinations, is used widely in power transmission lines overhauling.
At present there are two types of hangs when rope ladder suspension operation:
First is that hung from cross-arm (or conducting wire) to ground with longer rope ladder, suitable for 220kV and transmission line of electricity below
Maintenance is mainly used in livewire work, before personnel's climbing, first utilizes the exceptionally straight good ladder of tool on ground, allows ladder to have certain
Rigidity reduces rocking tendency of ladder during climbing, so that mitigating operating personnel climbs intensity, smoothly completes remote
The climbing of (20 meters or so).
Second is that being hung from cross-arm to from conducting wire with shorter rope ladder, the super-pressure and extra-high voltage suitable for 500kV or more are defeated
Electric line, the shaft tower for being primarily due to super-pressure and UHV transmission line using such hang is higher (30-80m),
Rope ladder is such as hanging to ground, required rope ladder length is very long, and bundle rolls that volume is very huge, and weight weight, inconvenient hill path is removed
Fortune, and operating personnel to climb 30-80m long rope ladder it is also unrealistic.Therefore it need to only be hung from cross-arm to leading with shorter rope ladder
At line, but because the lower end of common rope ladder is without fixed device, rope ladder can not be in exceptionally straight shape, and operating personnel climbs rocks up and down along rope ladder
When, cause rope ladder amplitude of fluctuation larger, needs to expend many physical strength of operating personnel, especially UHV transmission line electric clearance
Very big, conducting wire and cross-arm space length virtually increase the intensity that operating personnel climbs process, make operating personnel up to 10 meters or so
It is easy fatigue, people's operation in one day at most can be only done the workload of two Ji Ta, in order to also need a people to hold at cross-arm safely
Protection rope behind on-line operation personnel assists it to return at cross-arm, and operating efficiency is low.
For this purpose, we are it is necessary to develop a set of easy disassembly on rope ladder, and can be connected to rope ladder lower end on conducting wire, and
Rope ladder is tightened to exceptionally straight device, to improve operating efficiency.
