Problems solved by technology

The problems that this device exists are: 1, use insulating rope to connect insulating joystick joint when hooking on the straight pole tower, utilize the weight of wire clamp itself to bump into and block the wire in the process of falling, because the position of the operator is higher, affected by the wind force The impact is relatively large, so it is difficult to mount successfully at one time. The operation process is time-consuming and laborious, and the work efficiency is low. If it encounters strong winds, it will be more difficult to mount; Connected with the insulated joystick joint, the disclosed structure of the insulated joystick joint cannot realize quick connection and separation with the j...

Embodiment Construction

[0017] As shown in the figure, the transmission line pole tower grounding wire device has a wire clamp 1, which is composed of two symmetrically arranged splints 2 hinged by bolts 4, sleeved on the bolts 4 and located between the two splints 2 The shaft sleeve 13 and the torsion spring 5 sleeved on the shaft sleeve 13 are formed, and the two ends of the torsion spring 5 are respectively stuck on the tail ends of the two splints 2 . On one splint 2, a locking pin 3 is hinged. The middle part of the locking pin 3 is an arch protruding toward the entrance side of the wire clamp 1. On the other splint 2, a socket 202 is correspondingly provided. In the socket A pin 6 is fixed inside 202 , and the free end of the locking pin 3 is inserted into the socket 202 and can be stuck on the pin 6 . The front parts of the two splints 2 are symmetrically provided with arc-shaped jaws 201, and the tail ends of the two splints 2 are respectively provided with mutually symmetrical connecting pla...

Abstract

The invention discloses a ground line device of a power transmission line tower, and the device comprises a line clamp which consists of two articulated splints and a torsion spring, a block pin is arranged between the two splints, the line clamp is connected with a grounding seat by a flexible copper wire, the tail ends of the two splints are respectively provided with symmetric connecting plates, opposite surfaces of the two connecting plates are symmetrically provided with clamping blocks which are respectively provided with cross clamping slots, and one end of the flexible copper wire which is connected with the line clamp correspondingly are divided into two connecting terminals and are respectively connected with the two connecting plates. A dedicated hitching device of the ground line device comprises an insulating bar, the front end of which is provided with a connecting shaft, and the front end of the connecting shaft is provided with a cross shaft head which is matched with the cross clamping slot of the ground line device of the power transmission line tower. The device has the advantages of simple structure, convenient use, time-saving and labor-saving operation, high safety performance, light self-weight, easy carrying and labor-saving disassembly, and the device can realize the ground line hitching on various towers at one step and is especially suitable for a tower with a large rotation angle and a terminal tower.

Description

technical field [0001] The invention relates to a grounding wire device used in power outage operations of power transmission lines, in particular to a power transmission line tower grounding wire device and its hooking tool which are especially suitable for use on large-angle corners and terminal towers. Background technique [0002] In order to protect the personal safety of the operator during the power outage operation of the transmission line, the ground wire must be installed in advance. For a long time, when hooking large-angle corners and terminal tower grounding wires, because the hooking position is mostly outside the flip-chip clamp, the distance is relatively long and the horizontal distance, so it often needs to be hung hundreds of times in actual operation to succeed. It took more than two hours, time-consuming and labor-intensive. Patent No. CN200620022638.6 discloses a transmission line short-circuit grounding clamp device, which is composed of clamps, inner...
