L-shaped baffle block type lead end grounding clamp

Abstract

The invention relates to an L-shaped baffle block type lead end grounding clamp, which comprises a hanger provided with a grounding lead end and an operating rod, wherein the hanger comprises a left clamping part and a right clamping part, the left clamping part and the right clamping are internally connected with two rotatable tongue pieces, a horizontal boss extends out of the edge of the right clamping part, the horizontal boss is rotatably connected with the operating rod, the end of the operating rod is connected with a horizontal lock rod, and the hanger is internally provided with a lock port matched with the horizontal lock rod. The L-shaped baffle block type lead end grounding clamp further comprises a locking device capable of locking the horizontal lock rod in the lock port of the hanger. After a lead is clamped by a splayed clamping port formed by the two tongue pieces, the operating rod is rotated to make the horizontal rod enter the lock port, and the horizontal lock rod is blocked under the lead so as to prevent the lead from dropping from the clamping port. The L-shaped baffle block type lead end grounding clamp is easy to operate. Meanwhile, a locking device is arranged between the hanger and the horizontal lock rod, so that the phenomenon that the horizontal rod rotates relative to the hanger in the strong wind environment is eliminated, and the anti-dropping effect is enhanced.

Description

technical field [0001] The invention relates to a grounding wire clip, in particular to an L-shaped block-type wire end grounding wire clip. Background technique [0002] The grounding clamp at the wire end is a safety device used to temporarily short-circuit and ground the power-off transmission wire. Its function is to prevent the harm to the human body caused by the sudden incoming power or the induced voltage generated by the adjacent high-voltage live equipment during the maintenance of the high-voltage transmission wire. At present, the grounding clamps used by various power grid companies mainly include spiral type, duck tongue type, flat type and impact type. The duck tongue type is widely used because the clamping force generated when clamping the wire is relatively balanced, and it is relatively easy to operate. Its main structure is composed of a hook, two tongues, an operating rod, and two tension springs. The operating rod is connected to the hook. The hook has...

AI Technical Summary

Problems solved by technology

The large-diameter wire is located at the lower part of the tongue, that is, the bottom of the eight-shaped clamp, and the wire is easy to slip

In addition, the spiral grounding clamp is also widely used in industry because it holds the wire firmly. The spiral grounding clamp includes a chuck, a horizontal locking lever and an operating lever. The chuck is arranged in a U shape horizontally, forming A jaw opening in the horizontal direction, the horizontal locking rod is installed in the jaw and connected with the operating rod to form a T-shaped connection body. The operating rod and the bottom edge of the chuck are connected by threads. The horizontal locking rod is connected as a whole, which can drive the horizontal clamping rod to rise and fall in the jaw, so as to clamp or release the wire. However, because the jaw has a certain opening, the wire is clamped by thread adjustment, and the operating rod needs to be twisted. It takes a lot of turns to make the horizontal locking lever lock the wire in the jaw, which is very inconvenient to operate
