Self-locking power distribution network circuit continuing wire clamp installed by employing gunshot operation lever

Abstract

A self-locking power distribution network circuit continuing wire clamp installed by employing a gunshot operation lever comprises an integrated wire clamp main body with a left wire clamping nozzle and a right wire clamping nozzle, and a lower pressing plate (9) and an upper pressing plate (10) which are respectively assembled at the left wire clamping nozzle and the right wire clamping nozzle; the left wire clamping nozzle comprises a bottom plate with a bottom portion rectangular groove (1), a top plate with a top portion semicircle groove (2), an inner side back plate (4), an outer side wire self-locking pressing plate (3) and a lower boss (5) arranged at the bottom surface of the bottom plate, wherein a lifting bolt (11) penetrates from the bottom portion rectangular groove and is connected with the lower pressing plate; the middle portion of the top plate is provided with a notch (6), the wire self-locking pressing plate is installed in the notch through a pivot with a torsion spring; and the right wire clamping nozzle comprises a top plate with a top portion rectangular groove (7) in the nozzle, a bottom plate with a bottom portion semicircle groove (8) and an inner side back plate commonly used with the left wire clamping nozzle, and a locking bolt penetrates from the rectangular groove and is connected with the upper pressing plate. The self-locking power distributionnetwork circuit continuing wire clamp is cooperated with the gunshot operation lever, and is simple to operate and safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of wire splicing clips used for power outage maintenance and live maintenance of distribution networks. Background technique [0002] At present, in the live work of distribution network all over the world, Japan has realized 100% insulation pole operation of distribution network live work projects, and France has realized 90% insulation pole operation of distribution network live work projects. Domestic distribution network live work is mainly based on the insulating glove operation method in the insulated bucket arm vehicle, supplemented by the insulating rod operation method. Among them, the insulating rod operation method uses tie-up wires for overlapping drain wires, and the wires are difficult to tie tightly and difficult to wind. Higher, the use of parallel groove clamps, puncture clamps, C-type clamps, and J-type clamps in the operation requires extremely high skill levels of operators, is extremely ...

AI Technical Summary

Problems solved by technology

However, the existing gun-type operating lever is only suitable for American-style grounding clamps and jumper clamps. In the current domestic distribution network power outage maintenance and live maintenance, if the gun-type operating lever is to be used, there is no suitable one. Therefore, the development of a distribution network line connection clip that can be installed with a gun-type operating lever can greatly reduce the operating intensity of operators and improve the safety of operations.
