Problems solved by technology

The bucket arm truck driving into the substation site will destroy the civilized environment of the site. The safety performance of the bamboo ladder climbing operation is poor, the labor intensity of the workers is high, and the work efficiency is low. It will also prolong the power outage operation time and delay the power transmission time.

Embodiment Construction

[0010] The 220 kV outdoor isolating switch maintenance ladder of the present invention is realized in this way, see figure 1 , figure 2 , below in conjunction with the accompanying drawings to do a specific description. The main body rod 3 of the 220 kV outdoor isolating switch maintenance ladder of the present invention is composed of a supporting outer tube 4 and an inner tube 5 made of steel pipe or high-strength aluminum alloy material, and the inner tube 5 can be lifted up and down inside the supporting outer tube 4 . Inner pipe 5 is made fixing element by inner pipe ladder pedal 13. The lower platform 12 and the outer tube ladder pedal 8 are fixed on the supporting outer tube 4, and a single lower platform 12 or two lower platforms 12 can be arranged symmetrically. The bottom of the bottom and the inner pipe 5 are connected in a plug-in type, which is convenient to assemble. It can be assembled manually or by a crane, replacing the arm truck, so that the three phases ...

Abstract

The invention refers to a kind of GW6-16-17-21 outdoor isolating switch inspecting terrace applicable to 220KV. It is made up of an upper platform, rope tightening ring, main pole, a supporting outer pipe, inner pipe, a suspending ring, stirrup storing device, outer pipe stirrup, an upper fixing hardware fitting, a bottom board, a subjacent platform, inner pipe stirrup, a tightening hook. The character lies in: the main pole uses steel pipe or high intensity aluminum alloy material to produce the supporting outer pipe and the inner pipe, the inner pipe can rise in the supporting outer pipe, the bottom of the upper platform is connected with the inner pipe with tube type, the invention may sets a monomer subjacent platform or two platforms symmetrically left and right, there sets a upper platform on top of the main pole. The design is reasonable, the operation is simple. It is convenient, safe and reliable.

Description

technical field [0001] The invention belongs to maintenance equipment for large, medium and small repairs and accident handling of outdoor isolating switches in electric power systems, and particularly relates to a maintenance ladder suitable for 220 kV GW6-16-17-21 outdoor isolating switches. Background technique [0002] At present, when the domestic electric power system is overhauling outdoor isolating switches and handling large, medium and small repairs and accident handling, the traditional method is to use bamboo ladders and cooperate with bucket arm trucks to carry out operations. The bucket arm truck driving into the substation site will destroy the civilized environment of the site. The safety performance of the bamboo ladder climbing operation is poor, the labor intensity of the workers is high, the work efficiency is low, and it will prolong the power outage operation time and delay the power transmission time. Contents of the invention [0003] The present in...
