Aerial wiring pliers with track

Abstract

The invention discloses aerial wiring pliers with a track. The aerial wiring pliers comprise an upper jaw, a lower jaw, an insulating rod, a torsion spring and a bottom cover. A cylindrical portion of the lower jaw is coaxially mounted in an inner hole of a cylinder of the upper jaw in a clearance fit manner; the torsion spring is coaxially mounted at a hollow position of a cylinder of the lower jaw, one end of the torsion spring is fixedly connected with the upper jaw, and the other end of the torsion spring is fixedly connected with the lower jaw; the insulating rod is mounted at the hollow position of the inner periphery of the torsion spring, the bottom cover is welded to the lower end of the upper jaw, the insulating rod penetrates through the bottom cover, and the insulating rod and the bottom cover are mounted coaxially. By the aid of a track groove, the lower jaw moving vertically is capable of rotating along a center axis of the insulating rod, so that the problem of view blockage is solved. Owing to the torsion spring, completeness in closing and self locking of the upper and lower jaws can be realized, and the aerial wiring pliers are especially applicable to condition monitoring and routine maintenance of power equipment in the power industry.

Description

technical field [0001] The invention relates to equipment for equipment detection and state monitoring in the electric power field, in particular to a track-type high-altitude wiring clamp, which is especially suitable for ground-to-high-altitude equipment maintenance and wiring during daily maintenance. Background technique [0002] High-altitude wiring test equipment is a necessary equipment used by the power department for preventive tests and condition-based maintenance tests. It is mainly used for high-altitude connection tests of electrical equipment such as contact resistance, loop resistance, PT\CT dielectric loss, and capacitance testing. And detection, its purpose is to obtain the first-hand real-time data information of the state parameters of the power system. The working environment of high-altitude wiring test equipment is complex. The test location is usually in the field at a height of about 8.5 meters from the ground. Moreover, most of my country's regions h...

Problems solved by technology

[0004] The object of the present invention is to provide a rail-type high-altitude wiring pliers, which uses rails and springs to make the position of the lower jaw and the upper jaw stagger during operation, without blocking the line of sight, so as to facilitate hooking the upper jaw to the high-voltage line. It can overcome the shortcomings of the existing high-altitude wiring clamps, such as heavy weight, difficult ground operation, time-consuming and laborious, and has the characteristics of simple economy, easy operation and good safety.
