Description
Technical field
The utility model relates to line construction apparatus field more particularly to a kind of self-locking suspended structures for bolt clipper.
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 make, passes bolt clipper up and down according to regulatory requirements
It passs or high-altitude binding and fixing is carried out the work, operating personnel will pay very big physical demands.Therefore operating personnel often figure one
When facilitate and rest on bolt clipper is floating on electric utility.When the behaviors such as body rotations, operation of the operating personnel on bar have at any time
May cause and accidentally touch bolt clipper and it is caused to fall, if ground someone stay or by, once hit people and animals or
Person's ground installation will lead to a disaster, and 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 suspended structure for 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 suspended structure for bolt clipper, including
Tong arm, the tong arm are hingedly made of the first tong arm and the second tong arm, and first tong arm is equipped with the first linkage
Bar, the second tong arm are equipped with the second interlocking bar, and one end of the first interlocking bar is hinged on the first tong arm, one end of the second interlocking bar
Equipped with hinged shaft, hinged shaft is equipped with ratchet mechanism, and hinged shaft is rotatably arranged on the second tong arm, the other end of the first interlocking bar and second
The other end of interlocking bar is hinged；Second tong arm is equipped with suspension hook and strip, and strip is hinged on suspension hook by shaft, shaft
It is equipped with torsional spring for being against one end of strip on suspension hook inner ring, ratchet mechanism includes pawl and the spine that is fixed on hinged shaft
Wheel, one end of pawl and shaft are connected, and the other end of pawl is against on ratchet.
During operating personnel cuts wire rod using bolt clipper, the first tong arm is moved closer to the second tong arm, and hinged shaft exists
It is rotated counterclockwise on second tong arm, ratchet is driven to rotate counterclockwise, under the action of torsional spring, pawl blocks ratchet, prevents ratchet
It rotates backward, after bolt clipper cuts wire rod, the first tong arm cannot be reinflated with the second tong arm, and operating personnel can not reuse disconnected
Line tweezer.Operating personnel needs to hang over bolt clipper on appliance by suspension hook, and during hanging, strip can turn clockwise
Dynamic certain angle, since strip and pawl share a shaft, pawl then rotates clockwise certain angle and is detached from from ratchet, spine
Wheel can invert, and the first tong arm and the second tong arm are due to gravity expansion, to release the lock of the first tong arm and the second tong arm
Determine state, when subsequent operation, which removes bolt clipper, can be used.If bolt clipper is not hung on electric utility, bolt clipper can not
It uses, such operating personnel must use bolt clipper hanging after being finished bolt clipper on electric utility for next, can have
Imitating, which prevents operating personnel from floating bolt clipper, rests on electric utility, reduces bolt clipper falling from high altitude risk.
Preferably, the strip and pawl are integrally formed, the angle between strip and pawl is 90 ° ~ 170 °.Make suspension hook
During strip on electric utility rotates, pawl is easier to lift from ratchet, and ratchet is enable smoothly to invert for hanging.
Preferably, the angle between the strip and pawl is 120 ° or 150 °.
Preferably, the length of the pawl is greater than the length of strip.So that the end amount of movement of pawl is greater than strip
End amount of movement guarantees that pawl can be completely disengaged from ratchet.
Preferably, the length of the pawl and the length ratio of strip are 1.1 ~ 2:1.
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, ratchet mechanism locks bolt clipper, after bolt clipper is hung, lifts spine by the rotation of strip
The locking that pawl releases bolt clipper can just reuse, and be hung after promoting operating personnel to be finished bolt clipper, and it is floating to reduce bolt clipper
Phenomenon is put, bolt clipper falling from high altitude is avoided.
