Problems solved by technology

[0002] Although there are ladders with better safety in electric power construction for daily construction in the electric power department, they are relatively long in length and heavy in weight, and generally exceed 2 meters. According to the electric power regulations, ladders exceeding two meters in height must Supporting measures such as construction safety belts also bring a certain burden to the construction personnel. At the same time, many power constructions in the power sector involve basements, corridors, and public distribution boxes with narrow spaces. Due to the insulation ladders currently on the market They are all relatively long and heavy, and there is no one suitable for operation in these special environments and special circumstances, which will increase the difficulty of power construction, prolong the construction time, and easily cause staff fatigue and decline in construction quality.

Abstract

The invention discloses an insulated ladder for power maintenance, which comprises a first ladder post, a second ladder post, a first baffle plate, a second baffle plate, a rotating shaft and a telescopic chair, wherein the first baffle plate is fixed on the first ladder column, the second baffle plate is fixed on the second ladder column, the first and the second baffle plates are rotatably connected through the rotating shaft to be assembled into a work platform for an insulated ladder, a fixed pulley is arranged on the top end of the work platform, a stay cord is arranged on the upper end of the telescopic chair, and is wound on the fixed pulley, at least a first shaft sleeve which is matched with the rotating shaft is arranged on the bottom end of the first baffle plate, and at least a second shaft sleeve which is matched with the rotating shaft is arranged on the bottom end of the second baffle plate. The insulated ladder for power maintenance is convenient and reliable to use and excellent in insulativity, effectively reduces labor strength of operating personnel, is high in safety performance, effectively improves overall safety factor, and solves the problems that existing single ladders need to be firmly hold by people during the use process, and are easy to firmly keep off an operated meter box or can not be positively operated and the like.
