Pull-tab-shaped bayonet lock self-locking type lead end grounding clamp

Abstract

A pull-tab-shaped bayonet lock self-locking type lead end grounding clamp comprises an operation rod, a Y-shaped connecting rod, an L-shaped clamp, a falling-prevention mechanism, a T-shaped stop block and a second compression spring, wherein the operation rod and the Y-shaped connecting rod are connected in a hung manner through connecting holes; the Y-shaped connecting rod comprises left and right bent plates, the upper part of the Y-shaped connecting rod is connected with the operation rod in the hung manner through the connecting holes, and the lower part of the Y-shaped connecting rod is connected with the L-shaped clamp through a bolt; the upper part of the L-shaped clamp is connected with the Y-shaped connecting rod through the bolt, and a groove and the falling-prevention mechanism are arranged in the L-shaped clamp; the falling-prevention mechanism comprises a pull-tab-shaped bayonet lock and a first compression spring, the first compression spring is embedded in the L-shaped clamp, and the pull-tab-shaped bayonet lock is contacted with the T-shaped stop block under the action of the first compression spring; the T-shaped stop block is sleeved with the second compression spring, the upper end of the second compression spring is contacted with the T-shaped stop block, and the lower end of the second compression spring is contacted with the L-shaped clamp. With the adoption of the grounding clamp, problems that existing grounding clamps are complex in structure, easy to fall and the like can be solved, and the grounding clamp has the broad market prospect and the high business value.

Description

technical field [0001] The invention relates to a maintenance tool for high-voltage wires, in particular to a ring-type bayonet self-locking type wire end grounding wire clamp which is convenient to operate, safe and reliable. technical background [0002] The grounding clamp at the wire end is a safety device used to temporarily short-circuit and ground the power transmission wire in a power failure. At present, the clamps used by various power grid companies mainly include double tongue type, flat type, impact type and spiral type. Yet these several clamp structures all have unreasonable parts. The double-tongue type wire clamp generally adopts the method of hooking, which is suitable for round wires. With the weight of the insulating rod itself, the top surface is pressed down on the wire, and the tongues on both sides are clamped and fixed. It is easy to use, but it is easy to slip off. The jaws of the flat type wire clamp generally apply pressure through the clamping ...
