Live-working lifting and rotating insulated platform

Abstract

The present invention provides an electric operational lifting and revolving insulation platform provided with an upright rod. The upper and the lower ends of the upright rod are rotationally connected with an upper anchor ear and a lower anchor ear for enclasping a telegraph pole respectively; the external surface of the upright rod is provided with a rack; the internal side of the insulation platform is connected with an upper sliding bush jacketed on the upright pole and is provided with a worm wheel and worm conjugation; wherein, the worm is a drive shaft and the worm wheel is meshed with the rack; the external end of the insulation platform is hinged with the lower sliding bush jacketed on the upright rod through an insulation sway rod. The present invention with simple structure, safety and reliability bears the insulation platform on the telegraph pole by enclasping without a base, applicable to electric installation and maintenance in fields, mountain areas or narrow places; the present invention can lift the insulation platform by manually swaying or electrically driving the worm wheel meshed with the rack, and rotate the insulation platform around the upright rod by manually swaying the worm wheel connected with the upright rod, thus changing the radial position and facilitating the electric examination and operation of operators.

Description

technical field [0001] The invention relates to electric power maintenance or installation equipment, in particular to a lifting and rotating insulating platform for live work of high-voltage transmission lines. Background technique [0002] In the power industry, it is often necessary to overhaul and maintain power equipment such as porcelain vases and switches and transmission lines installed on the upper end of the utility pole. At present, the maintenance of such power equipment and lines is usually divided into two methods: blackout work and live work. Power supply needs to be stopped for blackout work, and the loss is relatively large. In the prior art, insulated bucket trucks, insulated ladders, insulated scaffolding or vertical lifting and insulating platforms are often used for live work, such as the vertical aerial work lifts disclosed in Chinese patents 00226829.9 and 00207299.8. These devices or Because there is no road operation vehicle, it cannot enter, or bec...

Problems solved by technology

At present, the maintenance of such power equipment and lines is usually divided into two methods: power outage operation and live operation. Power outage operation needs to stop power supply, and the loss is relatively large.

In the prior art, insulated bucket trucks, insulated ladders, insulated scaffolding or vertical lifting and insulating platforms are often used for live work, such as the vertical aerial work lifts disclosed in Chinese patents 00226829.9 and 00207299.8. These devices or Because there is no road operation vehicle, it is impossible to enter, or due to the large size, the installation of equipment is labor-intensive and time-consuming, which increases the cost of maintenance

What is more difficult is that these devices require at least a road or a piece of flat ground around the poles for the arm truck to enter or the equipment base to be placed, and such conditions are difficult to meet in the field and on hillsides; the second is that the lifting of these devices uses The hydraulic device further increases the volume and weight of the equipment itself, and the manufacturing cost is high

In addition, construction or maintenance operators hope to be able to change their radial positions relative to the utility poles to facilitate operation, but the existing lifting insulation platforms only have lifting functions and cannot rotate, which brings inconvenience and unsafe factors to the operators. , also affect work efficiency

Therefore, the difficulty of live construction and the existence of potential safety hazards in the above-mentioned places have always been a major technical problem for the power supply department and have not been effectively resolved.
