Abstract

The utility model relates to a tool for replacing a supporting insulator, in particular to a tool for replacing a supporting insulator of a high-voltage tube bus. The technical scheme of the utility model is that the tool for replacing the supporting insulator of the high-voltage tube bus mainly consists of a bracket, a wire stretcher hanger, a wire stretcher, a base, a fixed pulley, a rolling bearing and a pedal ladder stand; the bracket is made of a reinforced steel tube into a gantry bracket; a cross beam on the top of the bracket is provided with the wire stretcher; the bottom of the bracket is provided with the base; the fixed pulley and the rolling bearing are fixed on the middle part on one side of the bracket; and the pedal ladder stand is arranged on the middle lower part on the side of the bracket. The tool for replacing the supporting insulator of the high-voltage tube bus has the advantages of safety, reliability, simple operation, low manufacturing cost, reduction of working intensity of operators, greatly improvement of maintenance efficiency, low requirement for power-off range in the operating process and greatly shortened power-off time.

Description

High-voltage tube bus supporting insulator is changed instrument
One, technical field:
The utility model relates to a kind of electric power tool, and particularly a kind of high-voltage tube bus supporting insulator is changed instrument.
Two, background technology:
Along with continuous construction, the expansion of electrical network, to the health status requirement raising day by day of equipment, this just requires the operational reliability height of equipment, must shorten in order to guarantee uninterrupted power supply maintenance interruption duration.For example, the bus of the outdoor 220kV transformer station of existing operation, 220kV and 110kV battery limits generally are designed to hard bus in order to reduce floor space, are erected at the top of equipment, and isolating switch is for cutting the type cutter, and fixed contact directly is fixed on the bus.So bus is stressed bigger when disconnecting link moves, working space is less than normal when causing the bus maintenance simultaneously.And the traditional work mode to be crane be parked in that battery limits are maked an inspection tour on the road, if change phase bus away from road, owing to need stride across two buses in the outside, so need large-scale crane, the problem of its existence is: according to the traditional approach operation: duty cycle is long, and machinery expenses is big, dangerous big, the power failure area is big, and operations staff's workload is big, and indirect loss is big.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of high-voltage tube bus supporting insulator to change instrument, and it is safe and reliable, and is simple to operate, time saving and energy saving.
Its technical scheme is: mainly be made up of support, wire stretcher extension, wire stretcher, base, fixed pulley, rolling bearing, pedal cat ladder, described support adopts the reinforced steel pipe to make door shaped stent, install wire stretcher on the top cross-bar of support, the bottom of support is provided with base, one middle side part of support is fixed pulley and rolling bearing fixedly, and the middle and lower part is provided with the pedal cat ladder.
Twine the lifting rope on above-mentioned fixed pulley and the rolling bearing.
The beneficial effects of the utility model are: safe and reliable, simple to operate, cost of manufacture is low, has alleviated operating personnel's working strength, has improved overhaul efficiency greatly, little, the also shortening greatly of interruption duration of requirement power failure scope during operation.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
Mainly form with reference to accompanying drawing 1 the utility model by support 1, wire stretcher extension 2, wire stretcher 3, base 4, fixed pulley 5, rolling bearing 6, pedal cat ladder 7 and lifting rope 8, described support 1 adopts the reinforced steel pipe to make door shaped stent, install wire stretcher 3 on the top cross-bar of support 1, the bottom of support 1 is provided with base 4, one middle side part of support is fixed pulley 5 and rolling bearing 6 fixedly, the middle and lower part is provided with pedal cat ladder 7, with the convenient working personnel operation.In addition, twine lifting rope 8 on fixed pulley 5 and the rolling bearing 6.For weight reduction once considered to adopt aluminum alloy materials, the market material does not reach requirement or cost is too high but investigate, so adopt steelwork.During use, according to the diameter of post insulator, highly make small-sized door shaped stent, on the door shaped stent crossbeam, establish special bus lifting point, fixed form adopts adjustable bolt to be connected and fixed, in more the changing jobs of substation bus bar insulator, can make many pack supports and increase work efficiency according to the reality of work needs.
