Tipping bucket tackle special for equipotential operation of multi-loop vertically-arranged wires

Abstract

The invention discloses a tipping bucket tackle special for equipotential operation of multi-loop vertically-arranged wires and aims to provide the tipping bucket tackle special for equipotential operation of the multi-loop vertically-arranged wires, which can improve the operation efficiency. The special tipping bucket tackle comprises a body, a rod body which is fixedly arranged at an upper endof the body and extends upwards, a lifting ring fixedly arranged at an upper end of the rod body, a connecting lug fixedly arranged at a lower end of the body, a lower pulley which is rotationally installed on the connecting lug and used for being connected with an insulating rope, an upper pulley rotationally arranged on an upper portion of the body, a sealing door connected with the body, and aguide plate fixedly arranged at a lower end of the sealing door, wherein the body is provided with a through groove, a lower portion of the body is provided with an opening which is communicated withthe through groove and for a wire to enter, the sealing door comprises hook bodies symmetrically located on two sides of the body, ends of the two hook bodies are fixedly connected into a whole, the hook body comprises a transverse edge hinged to the upper portion of the body, a long edge which is fixedly connected with one end of the transverse edge and extends towards an opening, and a short edge which is fixedly connected with the other end of the transverse edge and extends downwards.

Description

technical field [0001] The invention relates to the technical field of power grid maintenance equipment, in particular to a special dump block for equipotential operation of multi-circuit vertically arranged conductors. Background technique [0002] In the live maintenance process of transmission lines, using the ladder method to enter the strong electric field for equipotential work is the most commonly used method in China at present. When equipotential workers enter the electric field through the insulating ladder method, there are the following problems: [0003] 1. When hoisting the head of the insulated soft ladder to the working phase wire, the operator needs to use the insulating operating rod to lift the traditional dump block to the wire. During this process, it takes three months to lift the tip block on the 110kV and 220kV lines. Up to four sections of operating rod, 4.5-6m long, require high arm strength of the operator, and the tackle below the dump block is co...

AI Technical Summary

Problems solved by technology

[0003] 1. When hoisting the head of the insulated soft ladder to the working phase wire, the operator needs to use the insulating operating rod to lift the traditional dump block to the wire. During this process, it takes three months to lift the tip block on the 110kV and 220kV lines. Up to four sections of operating rod, 4.5-6m long, require high arm strength of the operator, and the tackle below the dump block is connected with an insulating rope, the operation is difficult and time-consuming;

[0004] 2. When taking out the traditional dump block, the operator also needs to use the insulated operating rod to operate. The process of installing and removing the dump block takes a long time and the operation is more complicated;

[0005] 3. The design of the traditional dump block door sealing mechanism is flawed. In the actual use and maintenance process, the door sealing spring is directly installed on the door sealing plate and is easily damaged.
