Problems solved by technology

Because the distance between the wire and the cross arm is 2-3 meters, and the soft copper wire is connected to one side of the grounding clamp (the center of gravity will shift), and under the influence of natural wind, the grounding clamp cannot always maintain a vertical downward direction, so the installation Difficulty, affecting work efficiency
In addition, when this kind of grounding clamp is installed, it is necessary to touch the transmission line through the release. When removing it, the clamp is pulled off the transmission line by pulling the pull wire or the grounding wire, which often causes scratches and other damage to the wire.

Embodiment 1

[0023] A grounding clamp device, including a clamp body and an operating mechanism, one side of the clamp body is welded or crimped with a ground wire 7 through bolts, and the clamp body includes a clamp body 6 hinged by a rotating shaft 4 and a strong spring , the front part of the clamp body 6 is provided with a groove for clamping the transmission line, a slot is provided in the groove, and the graphite layer 5 is snapped into the groove through the slot; the tail of the clamp body is The end is provided with a pull cord 3 connected between the clamp bodies 6. The operating mechanism includes two insulating operating rods 1, one of which is provided with a hook structure 8 at the top of the operating rod 1, and a metal screw 11 at the top of the other operating rod 1. , and the metal screw 11 is provided with a cylindrical member 2 with an inverted cone cavity structure inside, and a bolt hole is provided on one side of the cylindrical member 2, and the cylindrical member 2 ...

Embodiment 2

[0025] The difference between this embodiment and the first embodiment lies in that: the tail of the clamp body is provided with a slope structure 9 matching the cavity structure of the inverted cone. The operating rod 1 is a telescopic operating rod, including an inner rod and an outer tube. The outer tube is provided with a compression bolt, and the inner rod and the outer tube are reliably connected by the compression bolt through the outer tube wall to compress the inner rod. connect. The hook structure 8 at the top of the operating rod 1 is a groove structure opened on the side of the top of the operating rod 1 .

Embodiment 3

[0027] A method for performing operations using the grounding clamp device of the above-mentioned embodiment 1 or embodiment 2, comprising the following steps:

[0028] 1) According to the distance between the operator and the transmission line during the specific operation, and the length of the operating rod 1 and the extension rod 10, different numbers of insulating extension rods 10 are prepared, and the staff arrives at the crossarm where the transmission line to be repaired is located on the tower , through the transfer rope, the grounding wire clamp device and the electric inspection inductor are transferred to the work cross arm. An insulating operating rod 1 is connected to an electric inspection inductor on its metal screw rod 11, and an electric inspection is carried out on the power transmission line to be repaired to ensure that the line has no voltage;

[0029] 2) After the electric test is completed, remove the electric test sensor and replace the cylinder part ...

Abstract

The invention discloses an earthing clamp device. According to the earthing clamp device, a stay cord used for being connected with two earthing clamp bodies is arranged at the rear end of an earthing clamp main body; the earthing clamp is smoothly clamped on a power transmission line through an operating rod connected with a cylinder piece provided with an inverted cone cavity structure inside and an operating rod provided with a hook at the top end. Rigid collision between the earthing clamp and the power transmission line is avoided in the whole process; the earthing clamp is opened before being taken down, and scratch or breakage of the power transmission line caused by adopting a stay wire to pull the power transmission line in the conventional method is avoided; the operation method of the earthing clamp device is simple and convenient, the entire hanging and dismounting process of the earthing clamp is smooth and controllable, and security of the power transmission line is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of power grounding clamps, in particular to a grounding clamp device and an operating method thereof that can effectively avoid damage to power transmission cables. Background technique [0002] When the transmission line is powered off, safety measures must first be taken for the maintenance line. The main work is to conduct electrical inspection and hang the ground wire. At present, the ground wire mounted on the tower mainly adopts the touch-type spring release ground wire clamp. Attach a thin insulating cord to the end of the ground clamp. The staff opens the wire clamp in advance, hangs it above the conductor with the insulated rope at the tail, and then loosens the insulation rope downwards, so that the ground wire clamps itself and the annealed copper wire connected to it, and falls rapidly under the gravity of itself and the annealed copper wire connected to it. After contact, the touch-type support...
