Disconnector maintenance hoisting bracket

Abstract

The invention relates to a maintenance tool, namely a disconnector maintenance hoisting bracket. The disconnector maintenance hoisting bracket comprises an upright rod; and the upper end of the upright rod is provided with a hanging hole for hanging a pulley. A base is arranged below the upright rod; two screw rods are respectively arranged on the base at the two sides of the upright rod; a pressing plate capable of moving and adjusting up and down is arranged on the base and is provided with three holes, and the two screw rods and the upright rod correspondingly pass through the three holes; and each screw rod is provided with a locking nut. The invention has the advantages that through shortening the length of embracing rods and changing the fixed mode of the embracing rods, the weight is reduced, so that the disconnector maintenance hoisting bracket is convenient to fixedly connect on the site, is light and flexible, is quick and convenient to disassemble and is safe and reliable; the work intensity is reduced, the condition that a plurality of persons maintain a group of switches is eliminated, and the labor efficiency is improved; the labor output is reduced, the work efficiency is high, and the maintenance quality is ensured.

Description

technical field [0001] The invention relates to a maintenance tool, which is an isolating switch maintenance hoisting bracket. Background technique [0002] In the prior art, during the overhaul process of the 66kV isolating switch of the power system, an aluminum alloy pole or maintenance platform is used for the overhaul. Using an aluminum alloy pole to work, the pole is long and heavy, and usually requires 8 people to fix the four pull wires holding the stem. The position of the pull wires is not easy to choose, it is not easy to control, and a safe distance cannot be guaranteed, which may easily cause electric shock. The height of the holding pole is not easy to control. It is very dangerous to set up the holding pole, and it is easy to cause the pole to fall, and it is very close to the live equipment. It is even more dangerous when moving the holding pole. This method is not suitable for working in the area near the live equipment ( see figure 1 ). The use of poles ...

AI Technical Summary

Problems solved by technology

Working with aluminum alloy poles, the poles are long and heavy, and usually 8 people are needed to fix the four pull wires. The position of the pull wires is not easy to choose, it is not easy to control, and a safe distance cannot be guaranteed, which may easily cause electric shock

The height of the holding pole is not easy to control. It is very dangerous to set up the holding pole, and it is easy to cause the pole to fall, and it is very close to the live equipment. It is even more dangerous when moving the holding pole. This method is not suitable for working in the area near the live equipment ( see figure 1 )

Using a pole for hoisting, poor stability, high risk, many times of dangerous work, low quality of maintenance, complicated operation of maintenance tools, and low work efficiency

The maintenance platform is large in size, heavy in weight, and complicated to install, requiring the cooperation of multiple people to install it, which takes a long time and makes it inconvenient to move at heights

These two working methods require a long working time, require a large number of personnel, are close to live equipment, are dangerous, cause low work efficiency, and cannot meet work needs.

Moreover, due to the large number of personnel and long working hours, the staff are prone to physical fatigue and danger, which is not conducive to safe production.
