Double-hook type grounding wire anti-falling hook device with opening in top end

Abstract

The invention discloses a double-hook type grounding wire anti-falling hook device with an opening in the top end. The double-hook type grounding wire anti-falling hook device is reasonable, rigorous and reliable in structure. The device can effectively prevent a grounding wire hook from falling off, and the problem that a grounding wire falls off is directly and fundamentally solved through a double-hook structure. The device comprises a grounding wire main hook, wherein the grounding wire main hook comprises a left hook top end, a right hook top end, a left hook side edge, a right hook side edge, an arc-shaped pressing sheet, a torsion spring, a connecting rod and an operating mechanism assembly; the grounding wire main hook is a hook which is opened or closed under the control of the connecting rod; the connecting rod comprises a left connecting rod and a right connecting rod; and after the hook is closed, the wire is clamped at the upper part of the hook under the action of the arc-shaped pressing sheet. The device further comprises a trigger element for opening and closing the hook, wherein the trigger element is a contact cambered surface; and the left side and the right side below the contact cambered surface are connected with the connecting rods respectively, and the left connecting rod and the right connecting rod are connected with the corresponding hooks on the two sides respectively.

Description

Technical field [0001] The present invention relates to a ground line off preventing means, particularly for a ground line to ground mount. Background technique [0002] After the transmission and distribution substation or power lines, electrical equipment maintenance work should be installed in the ground line side of the call may begin before and take effective preventive measures to prevent falling off the ground line, a ground line is one of the suspension of technical measures must be taken. If the ground wire is not standardized suspension mounting, the suspension structure irrational ground line structure or off during operation, when maintenance personnel working on the device or power outage the line is likely to suffer from sudden power outage maintenance call device or circuit damage, or direct exposure to induction of high voltage charging device produced. If the high-voltage device without sudden call will damage the ground line protection of life of maintenance per...

Problems solved by technology

[0003] According to the survey, the grounding wire hooks used in the State Grid Corporation of China system are all hooks of the same standard and type. To a certain extent, the hooks can be firmly hung on the power failure wires, but in unexpected cases, external forces may change its hanging. The posture even directly knocks it off the power failure wire. There have been related casualties in the system, and there are many other cases of electric shock caused by the ground wire falling off. All the hooks with openings cannot completely prevent the ground wire from falling off.

The measures taken in the power system to prevent the grounding wire from falling off are generally safety disclosure before work and strengthening the monitoring of the suspension status of the grounding wire during work, or using the method of winding the grounding wire to strengthen and supplement this effect. Fundamentally did not solve the problem of ground wire falling off
