Abstract
The utility model discloses a conductor grip for ground leads, which comprises a tong head, a fork mounting and a bolt. The tong head comprises a tong seat and a tong tongue. The tong seat is hinged on the fork mounting; the bolt is connected to the bottom of the fork mounting by bolt joint and the top of the bolt is abutted on the tong tongue; the two sides of the tong seat are respectively hinged on two fork arms of the fork mounting through thumbscrews; and rubber gaskets sleeved on the thumbscrews are provided at connections between the fork arms and the tong seat. The two rubber gaskets provided at the connections between the tong seat and the fork arms replace intrinsic slot and latch structures, so that the tong head can be fixed at any angles and the friction between the gaskets and the tong head and the fork arms is high enough to achieve a fixation effect without producing wear. At the meantime, thickness of the tong seat wall which is easily broken is increased so as to gain in strength without affecting the integral structure of the conductor grip.
Description
Technical field
The utility model relates to a kind of electric power overhaul security tool, relates in particular to a kind of earth connection wire clamp.
Background technology
Earth connection is the current-carrying part with primary equipment in the electric power system, insert the earth by lead, for preventing that closing on electrified body produces the important safety Work tool that guarantees staff's personal safety when electrostatic induction is got an electric shock or current/voltage appears in accident on the equipment that has had a power failure and circuit.
The high-voltage earthing line is made up of insulating bar, wire clamp, short-circuit line, earth connection, earth terminal etc., and in the regular job work of central station, earth connection is to use managing security tools and instruments very frequently, and hanging and disconnecting ground wire is the often projects of operation of operating personnel.The quality of earth connection directly has influence on the operating efficiency of operating personnel in transformer station.
When using, reality finds that it is the wire clamp of earth connection that earth connection damages the maximum position of appearance, accounts for 90% of all damages.And the damage of wire clamp has more in the present operating process, in the process of hanging earthing conductor in order to make solid and reliable being fixed on the busbar of wire clamp, operating personnel must adjust hook stick makes the binding clip of wire clamp be clipped on the busbar with angle with rational, wire clamp ruptures easily in this process, post-rift wire clamp can't be fixed on the busbar solid and reliablely, does not reach effective ground connection.Because wire clamp fails to clamp, thereby contact resistance is increased, by electric current the time, can produce very big heat.When operating personnel ran into the situation of wire clamp fracture when operation, necessary interrupt operation could continue operation after changing the earth connection wire clamp.Reduce the efficient of operation thus, destroyed operating continuity.
The adjustment of binding clip angle is to realize with the latch mating reaction of being located on the crotch yoke by the draw-in groove of being located on the pincers seat sidewall, in actual mechanical process, during the rotary work part, because discontinuity equalization, can produce certain stress between the latch draw-in groove, rupture in the final draw-in groove place of pincers seat sidewall that makes.
Summary of the invention
The purpose of this utility model provides a kind of earth connection wire clamp exactly in order to address the above problem, significantly reduced earth connection because the wire clamp bayonet socket damages and can not reliably be installed in the problem of earth terminal.
The purpose of this utility model is achieved in that
A kind of earth connection wire clamp of the present utility model, comprise binding clip, crotch and bolt, described binding clip comprises the pincers seat and is located at the interior pincers tongue of this pincers seat, described pincers seat is hinged on the described crotch, bottom and its top that described bolt is bolted in described crotch contact on the described pincers tongue, the two side of described pincers seat is articulated on two yokes of described crotch by wing screw respectively, and the joint of described pincers seat and yoke is equipped with the rubber washer that is sheathed on the described wing screw.
Above-mentioned a kind of earth connection wire clamp, wherein, the thickness of described pincers seat sidewall is 7mm.
The adjustment of existing wire clamp binding clip angle is owing to cooperate realization by draw-in groove and latch, owing to be subject to the setting of draw-in groove groove position, can't really realize adjusting at any angle, and the utility model installs two rubber washers additional in the joint of pincers seats and yoke and substitutes draw-in groove and latch, can realize " infinitely variable speeds ", make the binding clip can be in any fixed angle, the frictional force between pincers seat and yoke and the rubber washer also enough reaches fixed effect and don't as for producing wearing and tearing.Simultaneously, increase the thickness that the pincers seat sidewall of fracture takes place easily, make its intensity obtain strengthening greatly, and can not influence the structure of wire clamp integral body.By above-mentioned improvement, significantly reduced the spoilage of earth connection wire clamp, guaranteed operating personnel's personal safety, improved the efficient of operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See also Fig. 1, the utility model earth connection wire clamp, comprise binding clip 1, crotch 2 and bolt 3, binding clip 1 comprises pincers seat 11 and the pincers tongue of being located in this pincers seat 11 12, bottom and its top that bolt 3 is bolted in crotch 2 contact on the pincers tongue 12, the two side of pincers seat 11 is articulated on two yokes of crotch 2 by wing screw 3 respectively, and the joint of pincers seat 11 and yoke 2 is equipped with the rubber washer 5 that is sheathed on the wing screw 4, and the thickness H of pincers seat 11 sidewalls is 7mm.
Install two rubber washers 5 additional in the joint of pincers seat 11 and yoke 2 and substitute original draw-in groove latch structure, can realize " infinitely variable speeds ", binding clip 1 adjust to arbitrarily angled after, can realize the fixing of binding clip by screwing wing screw 3, and the frictional force between pincers seat 11 and yoke 2 and the rubber washer 5 also enough reaches fixed effect and don't wear and tear as for producing.
Simultaneously, the thickness H that pincers seat 11 sidewalls of fracture take place is easily increased to 7mm from original 5mm, make its intensity obtain strengthening greatly, and can not influence the structure of wire clamp integral body.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
Claims (2)
1. earth connection wire clamp, comprise binding clip, crotch and bolt, described binding clip comprises the pincers seat and is located at the interior pincers tongue of this pincers seat, described pincers seat is hinged on the described crotch, bottom and its top that described bolt is bolted in described crotch contact on the described pincers tongue, it is characterized in that the two side of described pincers seat is articulated on two yokes of described crotch by wing screw respectively, and the joint of described pincers seat and yoke is equipped with the rubber washer that is sheathed on the described wing screw.
