Hoisting device for maintenance of power equipment

Abstract

The invention discloses a hoisting device for maintenance of power equipment. The hoisting device for maintenance of the power equipment comprises a supporting base, a lead screw, a sliding block, a balancing weight, a clamping mechanism, a winding roller, a rigid pulling rope, a supporting stand column, a supporting cross rod, a supporting cross beam and a lifting frame, wherein the sliding block is rotatably arranged on the lead screw in a threaded connection mode; the balancing weight is arranged on the upper surface of the sliding block; and one end of the rigid pulling rope is connected with the winding roller, and the other end of the rigid pulling rope winds across a first guiding pulley and a second guiding pulley, penetrates through a channel formed between a first limiting pulley and a second limiting pulley, and then is connected with the clamping mechanism. By adoption of the hoisting device for maintenance of the power equipment, the power equipment can be clamped and fixed and can also be hoisted rapidly; and the position of the balancing weight can be adjusted conveniently, so that the balancing effect of the balancing weight can be brought into full play, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a hoisting device for electric equipment maintenance. Background technique [0002] There are many electrical equipment in the power system. According to their different roles in operation, they are usually divided into electrical primary equipment and electrical secondary equipment. The equipment that directly participates in the production, conversion, transmission, distribution and consumption of electrical energy is called electrical equipment. Primary equipment, in order to protect and ensure the normal operation of electrical primary equipment, the equipment that measures, monitors, controls and adjusts its operating status is called electrical secondary equipment. There are mainly various measuring meters, various relay protection and automatic devices, DC power supply equipment, etc. [0003] Power equipment is often installed at high places to prevent acciden...

AI Technical Summary

Problems solved by technology

[0003] Power equipment is often installed at high places to prevent accidents caused by contact between power equipment and non-power personnel. The substation is the assembly point of power transmission and distribution in the power system, which includes outdoor transformers, capacitors, filters and arresters, etc. Equipment, when there is a problem with these devices and needs to be replaced and installed, the staff will stand on the equipment frame to maintain and replace the equipment. The effect of holding and fixing is not good, and when the power equipment is hoisted with ropes, the power equipment is prone to shaking, which poses a safety hazard. Give full play to the role of counterweight
