Ground line device of power transmission line tower and hitching device thereof

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...

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 joystick, so it is difficult to quickly mount the grounding wire on the large-angle tension tower; 3. Due to the use of the clamp's own weight Hit the wire, so there are counterweights on the outside of the wire clamp, which makes the device heavy and inconvenient for the operator to carry when climbing the pole tower and working, which increases the working intensity and danger; 4. When removing it, pull it upwards forcefully The insulation rope is used to overcome the elastic force of the top spring, and finally the clamp is pulled out from the wire. Not only is it laborious to remove, but the operator is prone to danger when the force is too large, and it will also cause certain damage to the transmission wire.
