Counterweight hot-line work maintenance vehicle

Abstract

The invention relates to a counterweight hot-line work maintenance vehicle. A counterweight box is included. A support frame is arranged on the counterweight box; a climbing mechanism capable of climbing upwards through an insulating rope is arranged on the support frame; and an upper end of the support frame is provided with an installation frame driven by a driving mechanism to rotate, two sideportions of the installation frame are provided with a walking mechanism which clamps a wire and walks through the wire after the installation frame rotates, and an electric control module used for controlling the climbing mechanism, the driving mechanism and the walking mechanisms is arranged in the counterweight box. The counterweight hot-line work maintenance vehicle can be used for conductingwire load tests, balancing loads of all phases and providing rear protection hanging points for a counterweight vehicle for electric transmission line hot-line wire safe wire outlet work.

Description

technical field [0001] The invention relates to a maintenance vehicle for counterweight live working. Background technique [0002] At present, there are mainly three problems in carrying out the live work of long-distance outgoing conductors for erecting double-circuit lines on the same tower of 110kV-220kV: [0003] One is the problem of insufficient distance between phases after single-phase conductor load. After equipotential workers carry materials and tools to work on the conductors, the concentrated load on the conductors can sometimes reach more than 1000N, which increases the sag of the working phase conductors, and will inevitably reduce the phase-to-phase safety distance from the lower conductors, resulting in insufficient safety distance between phases , jeopardizing the safety of the workers, an object of the same weight as the workers must be placed on the lower wire to ensure the safety of the phases. In case of emergency, such operations can only be carried ...

AI Technical Summary

Problems solved by technology

After equipotential workers carry materials and tools to work on the wires, the concentrated load on the wires can sometimes reach more than 1000N, which increases the sag of the working phase wires, and will inevitably reduce the phase-to-phase safety distance from the lower wires, resulting in insufficient safety distance between phases , endangering the safety of the workers, the lower wire must be equipped with an object of the same weight as the workers to ensure the safety of the phases, and such operations can only be carried out by applying for a power outage in case of emergency.

[0004] The second is the problem of backup protection for long-distance lead-out operations

When the slope of the wire is large, it is difficult to pull the pulley, which not only increases the labor intensity of the operators, but also tends to cause the pulley to pull the wheel and the wheel to be deflected.

[0005] The third is that it is difficult to carry out the load test in advance

In order to ensure the safety of the outgoing line, the load test can be carried out on the conductor in advance, and there is no such test tool at present
