Clamp extension arm for cable path detector

Abstract

The invention discloses a clamp extension arm for a cable path detector. The clamp extension arm comprises an insulation rod and a clamp connecting seat, one end of the insulation rod, close to the clamp connecting seat, is provided with a sliding shell in a sliding and sleeved manner, one end of the insulation rod, close to a handle, is provided with a fixed shell in a sleeved manner, the sliding shell is connected with an insulation pull rod parallel to the insulation rod, the insulation pull rod is connected with a rotatable zigzag pull rod through a rotation structure, the fixed shell is hinged to a ratchet and a spring, and the sliding shell is provided with a pressing rope bolt, a steel wire rope and a circular clamp. According to the clamp extension arm, the requirement of increasing the safety distance is realized through the insulator rod, folding and unfolding of the clamp for the cable path detector are realized through the insulation pull rod and the zigzag pull rod, the locking of an opening of the clamp is realized through the ratchet, the release of locking is realized through rotation of the zigzag pull rod, the structure is simple, the operation is convenient, the safety factor is substantially increased, and the economic benefit and the social benefit are very high.

Description

technical field [0001] The invention relates to a cable path meter, in particular to an auxiliary tool for increasing the safety distance of the cable path meter. Background technique [0002] In order to beautify the appearance of the city, the construction of the distribution network in the urban area is mainly based on the laying of buried cables. Due to the rapid development of the city and the large changes in the ground, the direction of the buried cable needs to be determined in real time. The common method is to use a cable path meter to measure. When using the cable path meter, it is necessary to clamp the clamp on the three-phase cable, but since most of the three-phase cables are in the cable trench under the ring network cabinet and the cable cannot be powered off, how to increase the safety distance and fix the clamp conveniently and safely , urgently need to be resolved. Contents of the invention [0003] In order to overcome the shortcomings of the above-m...
