Live-working lifting and rotating insulated platform

Abstract

The invention relates to a lifting and rotating insulating platform for live work, which has a vertical pole, the upper and lower ends of which are respectively rotatably connected to the upper and lower hoops used to hold the utility pole tightly, the outer pole surface of the vertical pole is fixedly equipped with racks, and the inner side of the insulating platform It is connected with the upper sliding sleeve set on the vertical pole, and is equipped with a worm gear and worm pair, in which the worm is the drive shaft, and the worm gear meshes with the rack; the outer end of the insulating platform is connected with the sliding sleeve set on the vertical pole through the insulating diagonal strut hinged. The invention is simple in structure, safe and reliable, and the insulating platform is loaded on the utility pole through the hoop, without a base, and can be adapted to electrical installation and maintenance in the field, mountainous area or small places; the worm gear meshed with the rack is driven by hand or motor , the insulating platform can be raised and lowered; the worm wheel connected with the vertical rod can be rotated by hand to change the radial position of the insulating platform around the vertical rod, which is convenient for the operator to perform live maintenance operations.

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.

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.
