Offline hanging ladder especially used for suspension-type composite insulator

Abstract

The invention discloses an offline hanging ladder especially used for a suspension-type composite insulator. The offline hanging ladder comprises an insulation rope ladder. One end of the insulation rope ladder is connected to a hanging line aluminum hook which can be buckled to a lead via a shackle and the other end is connected to an adjustment lead screw via the shackle. The other end of the adjustment lead screw is connected to one end of an aluminum alloy cross arm fixed on a line iron tower cross arm head. The other end of the aluminum alloy cross arm is connected to a hook lead screw. The other end of the hook lead screw is provided with a hook which is buckled to a line iron tower material. By using the offline hanging ladder especially used for the suspension-type composite insulator, power transmission line employees can conveniently transfer wires up and down during acceptance check and maintenance work and the composite insulator is not damaged so that safety and work efficiency of work personnel are increased.

Description

technical field [0001] The invention relates to the technical field of tool manufacturing, in particular to a suspension-type composite insulator special off-line hanging ladder for climbing up and down wires. Background technique [0002] At present, in order to improve the anti-pollution flashover capability and operational safety of transmission lines, many lines use composite insulators with better anti-pollution performance, which increases the work of transmission line workers in acceptance inspection, annual inspection and defect elimination. Difficulty, because the surface of the synthetic insulator is made of silicone rubber umbrella skirt, and the staff have no support points on their feet when climbing up and down the wires, so they can only rely on hand strength and thighs to clamp the insulator, so it is more laborious to go up and down the tower, which is prone to accidents Falling, the work efficiency is not high, and the safety risk is great, and it is also e...

[0002] At present, in order to improve the anti-pollution flashover capability and operational safety of transmission lines, many lines use composite insulators with better anti-pollution performance, which increases the work of transmission line workers in acceptance inspection, annual inspection and defect elimination. Difficulty, because the surface of the synthetic insulator is made of silicone rubber umbrella skirt, and when the staff climbs up and down the wires, there is no support point on their feet, so they can only rely on hand strength and thighs to clamp the insulator, so it is more laborious to go up and down the tower, which is prone to accidents. Falling, the work efficiency is not high, and the safety risk is high, and it is also easy to damage the composite insulator shed, causing unnecessary losses
