Grounding wire hook for overhead transmission line power cut overhaul

Abstract

The invention relates to a grounding wire hook for overhead transmission line power cut overhaul, belonging to a transmission line overhaul device. The grounding wire hook is characterized by mainly comprising a hook body, a lower pressing plate, an upper fixing plate, ear plates, an operation ring, a rack, a gear shaft, a lower fixing plate, a grounding stud and a gear, wherein the upper part of the hook body is an arc hook head section extending leftwards, and the lower part of the hook is a cylindrical section; the cylindrical section of the hook body is fixedly penetrated in round through holes on the right parts of the upper fixing plate and the lower fixing plate; the gear shaft and the gear are arranged on the front and back ear plates of the cylindrical section of the hook body; the operation ring is fixedly arranged on the front end section of the gear shaft; a rack pole provided with the rack is penetrated in an upper rectangular through hole and a lower rectangular through hole on the left parts of the upper fixing plate and the lower fixing plate, and the rack is engaged with the gear; the lower pressing plate is sleeved on the cylindrical section on the upper end part of the rack pole; and the operation ring is tightly clamped and rotated by a metal hook on an insulated operation rod to drive the gear and the rack to engage and link so as to ensure that the lower pressing plate and a lead are compacted or loosened, so that grounding quickness and reliability are achieved.

Description

technical field [0001] The invention belongs to a power transmission line maintenance device, in particular to a ground wire hook for maintenance of a 35-220kV overhead power transmission line. Background technique [0002] With the improvement of people's living standards, the demand for electricity continues to increase, and the construction of power grids continues to speed up, so that the workload of power outage reconstruction of overhead transmission lines continues to increase: it is often necessary to open or overlap the bow lines of tension towers to reduce the scope and duration of power outages , in the course of such ever-increasing power outage maintenance operations, it is necessary to hang the grounding wire on the conductors on both sides of the tension tower, but due to the limitation of the working space, the hanging grounding wire is often suspended at a small angle instead of the normal vertical suspension, but The currently used grounding wire can only b...

[0002] With the improvement of people's living standards, the demand for electricity continues to increase, and the construction of power grids continues to speed up, so that the workload of power outage reconstruction of overhead transmission lines continues to increase: it is often necessary to open or overlap the bow lines of tension towers to reduce the scope and duration of power outages , in the course of such ever-increasing power outage maintenance operations, it is necessary to hang the grounding wire on the conductors on both sides of the tension tower, but due to the limitation of the working space, the hanging grounding wire is often suspended at a small angle instead of the normal vertical suspension, but The currently used grounding wire can only be hung vertically. Once it is hung at a small angle, it is easy to twist off the hanging head of the grounding wire and scrap it for the purpose of hanging securely, and lose the grounding effect
