Description
Technical field
The utility model relates to a kind of power equipment Work tool, specifically relates to a kind of earthing clamp that adapts to different size earthing conductor.
Background technology
In transformer station, each converting equipment below is all provided with earthing conductor, due to each interval in transformer station, asynchronism(-nization) puts into operation, the earthing conductor size of different interval is also different, existing earthing clamp size is single, only has a kind of size, with the earthing conductor of the existing earthing clamp clamping connection different size of single size, easily occur that clamping connection is not tight, even occur earthing clamp and earthing conductor appearance to seem contact and inner there is no effective virtual connection phenomenon being connected, virtual connection phenomenon makes the converting equipment residual charge of interruption maintenance and induced electricity cannot effectively import substation grounding electrical network, when staff works on converting equipment, can be wounded to fall by residual charge and induced electricity and cause loss of life or personal injury, serious threat substation equipment maintenance and repair personnel personal safety.Therefore, development is a kind of installs, removes conveniently, cost is low, the reliably cylinder earthing conductor of clamping connection different size, realize converting equipment and be connected with the reliable of earthing conductor, guarantee that the earthing clamp of the adapted to different size earthing conductor of the reliable electric discharge of converting equipment has very important engineering practical value.
Utility model content
The utility model provides a kind of the purpose of this utility model to be to overcome the deficiencies in the prior art part, provide a kind of and install, remove conveniently, cost is low, the reliably cylinder earthing conductor of clamping connection different size, realize converting equipment and be connected with the reliable of earthing conductor, guarantee the earthing clamp of the adapted to different size earthing conductor of the reliable electric discharge of converting equipment.The utility model solves the technical scheme that its technical problem adopts:
A kind of earthing clamp, is characterized in that: comprise two lever arms, a jointed shaft, a long screw and a clamp nut;
This lever arm comprises the clamping part and the connecting portion that link together, this connecting portion is provided with rectangular through hole, the inner surface of this clamping part is provided with three semicylindrical openings that diameter is different, three semicylindrical opening parallel interval arrange, the axis of described semicylindrical opening is consistent with the Width of described clamping part, the diameter maximum of the semicylindrical opening of close this connecting portion, the diameter minimum of the free-ended semicylindrical opening of close this clamping part;
This long screw is connected on the outer surface of clamping part of a lever arm, and this clamp nut can precession, screw out and this long screw is spirally connected;
The free end of the clamping part of described two lever arms is hinged by this jointed shaft, when the connecting portion of described two lever arms is folded while being close together, three semicylindrical openings on a lever arm respectively with another lever arm on three semicylindrical openings surround the cylindrical hole of three different-diameters.
The technical program is compared with background technology, and its tool has the following advantages:
When use, wire one end is connected with converting equipment, the wire other end is wrapped on long screw, then screw clamp nut, the fastened nut of the wire other end and lever arm reliably clamp.Earthing conductor is put in corresponding semicylindrical opening, and the connecting portion of two lever arms is folded to be close together, and through the rectangular through hole of two lever arms, the two is linked together with bolt, can realize the utility model and be connected with the reliable of earthing conductor.The utility model is simple in structure, and it is convenient to install, remove, and cost is low, and reliably the cylinder earthing conductor of clamping connection different size, realizes converting equipment and be connected with the reliable of earthing conductor, guarantees that converting equipment reliably discharges.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 has illustrated the schematic perspective view of a kind of earthing clamp of the utility model.
The master that Fig. 2 has illustrated a kind of earthing clamp shown in Fig. 1 looks schematic diagram.
Embodiment
Please refer to Fig. 1, a kind of earthing clamp of the present utility model, comprises two lever arms 10, a jointed shaft 20, a long screw and a clamp nut 30.
This lever arm 10 comprises the clamping part 12 and the connecting portion 14 that link together.This connecting portion 14 is provided with rectangular through hole 142.The inner surface of this clamping part 12 is provided with three semicylindrical openings 122 that diameter is different.Three semicylindrical opening 122 parallel interval settings, the axis of described semicylindrical opening 122 is consistent with the Width of described clamping part 12, the diameter maximum of the semicylindrical opening 122 of close this connecting portion 14, the diameter minimum of the free-ended semicylindrical opening 122 of close this clamping part 12.
This long screw is connected on the outer surface of clamping part 12 of a lever arm 10.This clamp nut 30 can precession, screw out and this long screw is spirally connected.The free end of the clamping part 12 of described two lever arms 10 is hinged by this jointed shaft 20.
Please refer to Fig. 2, in the time of folded being close together of connecting portion 14 of described two lever arms 10, three semicylindrical openings 122 on a lever arm 10 respectively with another lever arm 10 on three semicylindrical openings 122 surround cylindrical hole 40a, 40b, the 40c of three different-diameters.Described three cylindrical hole 40a, 40b, 40c are for clamping the cylinder earthing conductor of different size.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
