Embodiment 1

[0032] like Figure 1 to Figure 3 As shown, a transmission line personal security line with an insulating gripper includes a grounding clip, a wire clip and a sheathed wire connecting the grounding clip and the wire clip, and an insulating gripper, the insulating gripper includes an insulating outer sleeve 2 and an expansion inner sleeve 1 located inside the insulating outer sleeve and allowing the sheathed wire to pass through, the expansion inner sleeve 1 is provided with at least two expansion jaws 12 that can clamp the sheathed wire 5 . The insulating outer sleeve is provided with a non-slip grip pattern that is convenient to hold.

[0033] The sheathed wire may be a transparent sheathed soft copper wire. The insulating gripper can be made of common insulating materials such as nylon.

Embodiment approach

[0034] As an embodiment, the expansion inner sleeve 1 includes an inner sleeve portion 11 inserted into the insulating outer sleeve, the first end of the inner sleeve portion protrudes from the first end of the insulating outer sleeve and is threadedly connected with an insulating threaded sleeve Pipe 3, the second end of the inner sleeve portion is connected with at least two expansion jaws. By rotating the insulating threaded sleeve 3 , the expansion inner sleeve 1 is pulled to move axially toward the first end direction, and the expansion jaws 12 are contracted to clamp the sheathed wire 5 .

[0035] In order to facilitate clamping the sheathed wire 5, the at least two expansion jaws 12 are two semicircular truncated portions, an expansion gap is provided between the two semicircular truncated portions, and the half faces of the semicircular truncated The clamping groove in which the sheathed wire 5 fits. And the clamping groove is a circular arc groove or a V-shaped groov...

Embodiment 2

[0044] like Figure 4 As shown, in this embodiment, the expansion inner bushing 1 is an expansion claw structure composed of two half-cylinders as a whole, and an expansion gap is set between the two half-cylinders, and the half-sections of the half-cylinders have an expansion gap. There is a clamping groove matched with the sheathed wire, the half cylinder is provided with a semicircular truncated part that acts with the insulating outer sleeve, and the end of the insulating outer sleeve is threadedly connected to drive the two half cylinders to shrink and make them shrink. The clamping groove clamps the insulated threaded sleeve 3 with the sheathed conductor. When the insulating threaded sleeve 3 is tightened, the two semi-columns move axially, and the two semi-columns are squeezed to shrink at the same time, and the sheathed conductor 5 is pressed through the clamping groove, so that the insulating gripper is fixed on the sheathed conductor. 5 At a certain position, the ha...

Abstract

The invention discloses a transmission line personal security wire with an insulating gripper, comprising a grounding clip, a wire clip and a sheathed wire connecting the grounding clip and the wire clip. The insulating gripper comprises an insulating outer sleeve and a The inner side is an expansion inner sleeve through which the sheathed wire can be passed, and the expansion inner sleeve is provided with at least two expansion jaws that can clamp the sheathed wire. The invention uses a detachable insulating gripper to replace the insulating rope of the original personal security line, and determines a suitable position on the sheathed wire according to the length of insulators of different voltage levels, combined with its own body condition and working habits, and fixes the insulating gripper. In this position, after the operator fixes the grounding clip to the tower, he holds the insulating gripper to realize the hanging and dismantling of the personal security line.

Description

technical field [0001] The invention relates to electric power tools, in particular to a personal security line for transmission lines with insulating grippers. Background technique [0002] Personal security lines are called "life-saving lines" by power line workers. They are one of the tools commonly used by power line workers and are frequently used. The current personal security wire consists of four parts: grounding clip, transparent sheathed soft copper wire, insulating rope and wire clip. [0003] Operation method: The operator fixes the grounding clip of the personal security wire on the iron piece of the tower, breaks the wire end clip, and realizes the hanging and dismantling of the security wire by controlling the insulating rope, using the wire clip, the transparent sheath soft copper wire and the grounding clip Reliably ground the wire to effectively prevent the operator from getting electric shock. [0004] There is a problem: [0005] 1. Insulating rope par...
