Bolt clipper preventing falling off

Abstract

The invention relates to the field of line construction equipment, in particular to a bolt clipper preventing falling off. The bolt clipper comprises a bolt clipper head, a first bolt clipper arm anda second bolt clipper arm. The first bolt clipper arm is hinged to the second bolt clipper arm. The first bolt clipper arm is provided with a linkage rod. The second bolt clipper arm is provided withreceding holes. The linkage rod penetrates through the receding holes. The second bolt clipper arm is internally provided with a guide sleeve and a positioning pin. The positioning pin is slidably arranged in the guide sleeve. A spring is arranged in the guide sleeve. The end, away from the spring, of the positioning pin is in contact with the linkage rod. The linkage rod is provided with a positioning hole matched with the positioning pin. A lift hook and a clamping strip are arranged on the outer wall of the second bolt clipper arm. The middle of the clamping strip is hinged to the lifting hook by a rotating shaft. The rotating shaft is provided with a torsional spring. A pulling rope is arranged at the other end of the clamping strip. The pulling rope penetrates through the guide sleeveand is connected with the positioning pin. Operators can be prevented from placing the bolt clipper on electric equipment in a floating mode, working efficiency of the operators can be improved, andphysical output can be reduced.

Description

technical field [0001] The invention relates to the field of line construction equipment, in particular to an anti-fall bolt cutter. Background technique [0002] In the process of project construction, line maintenance and equipment defect elimination, distribution network lines often need to cut large cross-section metal wires such as cables, wires, steel wire ropes, and steel bars. Manual bolt cutters, commonly known as large calipers, are divided into hand pressure type and ratchet type. They are widely used in electric power construction, operation and maintenance because of their simple operation and low price. [0003] In electric power construction, on-site workers are in high altitude (on poles or iron towers). Since the use of bolt cutters on site poles cannot be completed at one time, it needs to be used in stages. According to the requirements of the regulations, the The bolt cutters are passed up and down or tied up and fixed at high altitude to carry out work,...

AI Technical Summary

Problems solved by technology

When the operator's body rotation and operation on the pole may cause the bolt cutter to fall down by mistake at any time, if someone stays or passes on the ground, once it hits people, animals or ground equipment, it will cause an accident. There is a potential fall hazard

[0004] Chinese Patent Authorization Announcement No. CN 203826848 U, date of authorized announcement is 2014.09.10, named "Bolt Cutter Hook", discloses a hook for fixing bolt cutters on the crosspiece, but this bolt cutter The hook does not prevent the operator from floating the bolt cutter on the electrical installation, and there is still a potential fall hazard
