Embodiment Construction

[0024] see figure 1 with figure 2 , the rotary insulating ladder used for live work on power distribution lines of the present invention includes a platform connecting seat frame 1, an insulating platform 2, a pair of platform support bars 3, a vertical ladder 4, and a pair of vertical ladder support bars 5 , a vertical ladder small platform 6, a hoop device 7, a rotating device 8, a safety device 9 and a hoop 10, wherein,

[0025] The platform connection frame 1 includes two upper and lower horizontal bars 11 and two vertical bars 12 spanning the horizontal bars 11. The horizontal bar 11 is composed of two layers of metal plates and has an arc matching the utility pole;

[0026] The insulating platform 2 includes a pair of supporting crosspieces 21 and a horizontal platform plate 22 fixed on the supporting crosspieces 21. The outer ends of the supporting crosspieces 21 are fixedly connected to the two ends of the crossbar 11 at the upper end of the platform connecting frame...

Abstract

The invention discloses a rotary insulating ladder for distribution line live working, which comprises a platform connecting seat frame, an insulating platform, a pair of platform support rods, a vertical ladder, a pair of vertical ladder brace rods, a small vertical ladder platform, a hoop device, a rotary device and a safety device. Different from the traditional insulating platform, the rotary insulating ladder for distribution line live working of the invention has large action radius (360-degree rotation), high bearing capacity, vertical working range which can be larger than human body height, good stability, convenient installation and flexible operation, and is incomparable with other insulation platforms. The rotary insulating ladder widens the working range of live working, makes the region on which the live working can not be performed safely and conveniently realize live working, greatly improves the safe operation of the line, and reduces and avoids the power failure construction on the regions.

Description

technical field [0001] The invention relates to a working tool in the electric power industry, in particular to a rotary insulating ladder used for live working of power distribution lines. Background technique [0002] Live work refers to work performed on equipment or lines that are not powered off. For example, on live electrical equipment or lines, special methods (such as using insulating rods, equipotential, water flushing, etc.) are used to test, maintain, overhaul and replace individual parts. [0003] Live work on 10kV power distribution lines in urban areas is mainly carried out with insulated bucket trucks and insulated gloves. However, some engineering projects are limited by the working radius of high-altitude bucket trucks, and vehicles cannot enter fields, green belts, alleys, etc. for live work. lap. If it is carried out in the form of power outage, it will affect the reliability of power supply. For this reason, people in the industry have also developed ...
