Wire clamping opening and closing linkage device of fault indicator

Abstract

The invention discloses a wire clamping opening and closing linkage device of a fault indicator. The wire clamping opening and closing linkage device comprises a screw transmission shaft, a wire pressing mechanism, a screw fixing seat and an opening and closing mechanism. The screw transmission shaft comprises an upper threaded rod and a lower threaded rod. The wire pressing mechanism comprises awire pressing sliding base, a wire pressing support and a wire pressing base. The upper threaded rod is sleeved with the wire pressing sliding seat in a sliding mode; the wire pressing support is rotatably mounted on the wire pressing sliding seat; one end of the wire pressing support is movably connected with the screw fixing base, and the wire pressing base is movably connected with the other end of the wire pressing support. The opening and closing mechanism comprises an opening and closing sliding base, a sliding plate and a pulley; the opening and closing sliding base is slidably arrangedon the lower threaded rod in a sleeving mode. A first sliding groove is formed in the sliding plate, and the pulley penetrates through the first sliding groove to be arranged on the opening and closing sliding base. According to the invention, a wire clamping mechanism and the opening and closing mechanism are used as linkage structures, so that the wire clamping / loosening and upper and lower shell opening and closing actions can be executed in a linkage manner by one action input; the mounting and dismounting operation process is simplified, and the problem of harsh mounting conditions in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of monitoring equipment for power transmission and distribution lines, and more specifically relates to a line jam opening and closing linkage device for a fault indicator. Background technique [0002] Transmission line fault indicator is widely used in transmission and distribution lines to indicate the fault of the line in a certain section. When a fault occurs on the line, the indicator in the section will send out a warning signal, which can help line inspectors quickly determine the faulty section and find the fault point. In the process of use, the fault indicator is arranged on the wire of the transmission line, and the transmission line is generally higher than the ground, so the installation and disassembly of the fault indicator are relatively difficult. [0003] In the prior art, the clamping mechanism and the opening and closing mechanism of the fault indicator are two sets of independent actio...

AI Technical Summary

Problems solved by technology

In the process of use, the fault indicator is set on the wire of the transmission line, and the transmission line is generally higher than the ground, so the installation and removal of the fault indicator are difficult

[0003] In the prior art, the clamping mechanism and the opening and closing mechanism of the fault indicator are two sets of independent action actuators. Therefore, when the fault indicator is installed or removed, it is necessary to tighten the screw of the clamping mechanism to clamp the cable and The closing mechanism of the upper and lower shells of the fault indicator can only realize the two actions of closing the upper and lower shells. Therefore, it means that the cable installed on the cable can work normally. Both installation and disassembly are cumbersome and can only be realized with the help of special tools. Moreover, when the fault indicator itself has problems or has When other problems need to be disassembled, the line must be powered off and operated at close range, which not only affects the normal power supply of the line, but also requires the use of large machinery such as bucket trucks, which is not only inconvenient to operate, labor-intensive, but also has potential safety hazards
