Description
Technical field
The utility model relates to line construction apparatus field more particularly to a kind of self-locking bolt clippers.
Background technique
Distribution line is regular during project construction, line maintenance and elimination of equipment defect to be needed to cut cable, leads
The big cross section metal wire rod such as line, wirerope, reinforcing bar.Manual bolt clipper is commonly called as giant bow compass and is divided into hand and ratchet-type, because of operation
Simply, cheap and be widely used in the work such as power construction, O&M.
In power construction, on-site personnel is to be in high aerial (on electric pole or on steel tower), due on bar at the scene
The use of bolt clipper is not that once can be completed, interim circulation is needed to use, it will be above and below bolt clipper according to regulatory requirements
Transmitting or high-altitude binding and fixing are carried out the work, and operating personnel will pay very big physical demands.Therefore operating personnel often schemes
Facilitate to float bolt clipper for the moment and rest on electric utility.When the behaviors such as body rotations, operation of the operating personnel on bar at any time all
It is likely to cause and accidentally touches bolt clipper and it is caused to fall, if ground someone stays or passes through, once hit people and animals
Or ground installation will lead to a disaster, it is dangerous that there are potential falling from high altitude.
Chinese patent Authorization Notice No. CN 203826848 U, authorized announcement date 2014.09.10, entitled " bolt clipper
Hook " discloses a kind of hook for bolt clipper to be fixed on crosspiece, but this bolt clipper hook can not prevent from making
Bolt clipper is floated and is rested on electric utility by industry personnel, however it remains danger of potentially falling.
Utility model content
The purpose of this utility model is to overcome rest on electric utility because operating personnel floats bolt clipper in the prior art
On cause there are the deficiency of falling from high altitude danger, provide it is a kind of can prevent operating personnel from resting on bolt clipper is floating on electric utility,
The self-locking bolt clipper for improving operating personnel's working efficiency simultaneously, reducing physical demands.
To achieve the goals above, the utility model uses following technical scheme:
A kind of self-locking bolt clipper, including
Binding clip, the first tong arm and the second tong arm, the first tong arm and the second tong arm are hinged, and first tong arm is equipped with linkage

Positioning pin, positioning pin are slidably arranged in guide sleeve；Be equipped with spring in the guide sleeve, the both ends of spring respectively with the bottom of guide sleeve
With positioning pin contacts, positioning pin is contacted far from one end of spring with interlocking bar, and interlocking bar is equipped with and the matched positioning of positioning pin
Hole, when binding clip cuts wire rod, positioning pin is located in location hole；The outer wall of second tong arm is equipped with suspension hook and strip, strip
Middle part is hinged on suspension hook by shaft, and shaft is equipped with the torsional spring for being against one end of strip on suspension hook inner ring, strip
The other end be equipped with drawstring, drawstring penetrates into guide sleeve, and one end that drawstring is located in guide sleeve is connected with positioning pin.
During operating personnel cuts wire rod using bolt clipper, the first tong arm is moved closer to the second tong arm, interlocking bar
Opposite relief hole is subjected to displacement, and when binding clip cuts wire rod, the first tong arm and the second tong arm reach the limit of position and cannot continue at this time
Close, positioning pin drops into location hole, and bolt clipper can not be reused by lockking the first tong arm and the second tong arm, operating personnel.Operation
Personnel need to hang over bolt clipper on electric utility by suspension hook, and during hanging, strip can rotate certain angle, pass through
Positioning pin is pulled out location hole by drawstring, releases the lock state of the first tong arm and the second tong arm, and when subsequent operation takes bolt clipper
It is lower to can be used.If bolt clipper is not hung on electric utility, bolt clipper is not available, and such operating personnel must will break
Pincers hanging, so that next time uses, can prevent operating personnel from floating bolt clipper and rest on electric utility, reduce very on electric utility
To elimination bolt clipper falling from high altitude risk.
Preferably, the interlocking bar is arc-shaped, the center of circle of the hinge joint and interlocking bar of the first tong arm and the second tong arm
It is overlapped.When guaranteeing that the first tong arm and the second tong arm open and close, interlocking bar can successfully shuttle in relief hole, be not susceptible to card
, while the extension elongation of positioning pin can be made to be consistent, until falling into location hole, it is conducive to stable structure.
Preferably, the interlocking bar is located at one end on the first tong arm close to binding clip.Close to binding clip, interlocking bar can be made
Be sized to it is smaller.
Preferably, the interlocking bar is equipped with guide groove, positioning pin is located in guide groove far from one end of spring, positions hole location
In the bottom of guide groove.Guide groove plays guiding and position-limiting action to positioning pin, steadily falls into location hole conducive to positioning pin.
Preferably, being equipped with fixed pulley in second tong arm, fixed pulley is located at the top of guide sleeve, and drawstring passes through fixed sliding
Wheel.Fixed pulley changes the trend of drawstring, adjusts the Impact direction of drawstring, and drawstring is made to be easier to pull positioning pin.
The beneficial effects of the utility model are: (1) bolt clipper is when not in use, can be hung by suspension hook in electric utility
On, it does not need up and down to transmit bolt clipper or high-altitude binding, reduction operating personnel's physical demands promotes working efficiency；(2) break
As soon as clamping every cutting time wire rod, positioning pin falls into location hole and locks bolt clipper, after bolt clipper is hung, is pulled by drawstring
Positioning pin can just reuse, and be hung after promoting operating personnel to be finished bolt clipper, prevent operating personnel from floating bolt clipper and put
On electric utility, it is dangerous to reduce bolt clipper falling from high altitude.
