Light self-adaptive derrick insulation extension ladder

Abstract

The invention belongs to the technical field of power. A light self-adaptive derrick insulation extension ladder comprises an insulation extension ladder body and is characterized in that a top self-derrick device is fixedly mounted at the upper end of the insulation extension ladder body, and a bottom self-derrick device is fixedly mounted at the lower end of the insulation extension ladder body;the top self-derrick device comprises an upper right hoop device, an upper left hoop device, an upper right cap type connecting piece, an upper left cap type connecting piece, an upper U-shaped self-adaptive rubber pad, an upper tensioner and an upper belt; an installation shaft on an installation frame of the upper tensioner is fixed to the front end of the upper right hoop device through a bolt, the left end of the upper belt is fixed to the front end of the upper left hoop device through a bolt, and the right end of the upper belt is inserted into an insertion hole of a rotating shaft of the upper tensioner; and the bottom self-derrick device comprises a telescopic fixing support, a lower right hoop device, a lower left hoop device, a lower U-shaped self-adaptive rubber pad, a lower tensioner and a lower belt. As the insulation extension ladder adopts the top self-derrick device and the bottom self-derrick device to be fixed with a telegraph pole, the stability of the insulating extension ladder is very good and the safety is also very good.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a light-duty self-adapting pole-holding insulating telescopic ladder. Background technique [0002] According to the national standard GB / T3608-2008 "Regulations on Classification of Working at Heights": "Any work at a height where the falling height reference plane is more than 2 meters (including 2 meters) may fall is called high-altitude operation." In the process of emergency repairs in the city, substation maintenance, and meter reading, operators often encounter high-altitude operations, and ladders are used more frequently, and general ladders (such as insulated telescopic ladders) lean on utility poles (or equipment racks, buildings) However, since the top and bottom of the insulating telescopic ladder cannot be fixed reliably, the bottom of the insulating telescopic ladder is prone to slide and the ladder rolls over, which brings certain safety hazards...
