Description
Technical field
The present invention relates to electric power overhaul technical field of tools, is specifically a kind of work for high-altitude Electric Power Line Overhaul
Ladder.
Background technology
In recent years, since circuit creates and extends, steel tower height is generally increased.Ultra-high-tension power transmission line under external force,
Broken string or short circuit problem often occurs.Generally use working stand is climbed to power circuit and it is carried out maintenance.
At present, it is common to use be that rope ladder is overhauled, rope ladder is first hung on conducting wire, then ground coordinate personnel keep a firm hand on it is soft
Ladder, working at height personnel are climbed to terraced head, start wiring work.Chinese patent（Authorization Notice No.：CN202651688U）Disclose
A kind of aerial platform for ultra-high-tension power transmission line maintenance, although the work that can mitigate working at height personnel significantly is strong
Degree, and enhance the safety coefficient of working at height personnel；The aerial work of working at height personnel is also convenient at the same time.But due to soft
Ladder is very soft, easily upset, creeps very laborious, certain difficulty is brought to working at height personnel, and rope ladder is very unstable, left
The stability that right wobble effects service personnel stands, it is easy to fall from rope ladder, especially high-altitude Electric Power Line Overhaul, it is dangerous
Coefficient is high.
Chinese patent（Authorization Notice No.：CN205503002U）Disclose a kind of insulating ladder, although insulating ladder ladder with around
The axis parallel with cross bar is rotatably equipped with guardrail, guardrail have in its rotational travel the expansion position vertical with terraced body and with
Terraced body it is parallel pack up position, and it is spacing to carry out for guardrail by locking structure locking in expansion position and locking position, is so transporting
Guardrail is turned to during with storage and packs up position, placement space is saved and is also less likely to be damaged guardrail, when in use, guardrail is overturn
It is very convenient to use to expansion position.But the labor intensity of service personnel is the increase in, can not rest and recover body
Power, the maintenance for not applying to high-altitude power circuit use.Using the ladder of steel construction, although solving, rope ladder climbing is laborious to ask
Topic, but its support is on the ground, it is necessary to which the supporting rack of auxiliary supports, and ladder upper end can not be fixed, the feelings of crank
It can still turn on one's side under condition, it is also difficult to meet that the maintenance of high-altitude power circuit uses.
