Live wire insulated lifter

Abstract

The invention discloses a live wire insulated lifter. The live wire insulated lifter comprises an insulated support, a gear transmission device, a rope, an insulated lifting hook and a rocking handle, wherein the gear transmission device is fixedly arranged on the supporting column of the insulated support; a bidirectional ratchet mechanism for self-locking is arranged in the gear transmission device; the rope is hung on the insulated support; one end of the rope is fixedly arranged at the top of the insulated support and is connected with a movable pulley and the other end is connected with a fixed pulley in the gear transmission device; the insulated lifting hook is fixedly arranged at the lower end of the movable pulley and supports a live wire; the rocking handle is connected with the gear transmission device and drives the gear of the gear transmission device to rotate. The live wire insulated lifter has the advantages that the effect of saving labor is realized, the stability of the live wire is guaranteed, the working personnel is prevented from being in contact with the live wire for a long time, and the personal safety of the working personnel is improved.

Description

technical field [0001] The invention relates to the technical field of live work in distribution networks, in particular to an insulation lifter for live wires. Background technique [0002] When construction and maintenance are required on the distribution line, in order to ensure the normal production and living needs of the users on the line, the main line is not powered off, and the work performed by the operators is live work on the distribution network. There are four types of work in the distribution network live work. According to the proficiency of each unit for primary live work and the requirements of new work items, the work of newly installing or replacing pin insulators and lightning protection post insulators has become the main work of many units. At the same time, in order to ensure the reliability of power supply, such work is usually not included in the blackout plan. [0003] In the traditional process, when new installation or replacement of pin insulat...

AI Technical Summary

Problems solved by technology

Install the insulation bracket on the cross arm, and the height of the insulation bracket is also fixed. The operator who performs live work first removes the aluminum wire used to fix the live wire to the insulator, and removes the live wire from the groove on the insulator. Take it out, then lift the live wire to the same height as the insulating support, and place it on the insulating support so that the live wire is in a safe range. In the groove, the whole process requires manual lifting and lowering of the live wires, which is laborious. Moreover, the contact time between the staff and the live wires will be long and the risk is high, and the insulation support is firm after installation. Insufficient, it is easy to deflect when encountering a large span or a slight corner, the live wire is unstable, and there may be a danger of the wire falling from the insulating support
