Description
Technical field
The utility model is related to power system to send out, becomes, power distribution station grid switching operation technology, specifically adjustable multi-angle
Drop bar.
Background technology
High-voltage grounding wire, as a kind of necessary power failure technical measures in power system, is to ensure electric operating work safety
Last barrier, current most widely used ground wire wire end terminal is detached type and spiral compression formula earthing clamp.Its
In some vertical arrangement wires scene installing high-voltage grounding wires when there is the low hidden danger of reliability.Usually using existing high pressure
When ground wire is installed to vertical arrangement wire, because there is the reality such as spacing is too small, installing subtended angle is excessive in vertical distribution wire
Situation, very big difficulty is caused to installation, even if after the completion of installing, ground wire also easily comes in contact that bad, the phenomenon such as come off,
Reliability is substantially reduced, the security of line maintenance work is directly affected.
Utility model content
The purpose of this utility model is to provide adjustable multi-angle drop bar, and insulated operating rod earthing clamp is artificially rolled over
Suitable angle is bent to, is reached and is changed the purpose that earthing clamp operates direction, with the wire arranged suitable for different directions, make work
Make the completion installing ground wire operation that personnel can smoothly, safe.
In order to reach above-mentioned purpose, the utility model employs following technical scheme, adjustable multi-angle drop bar, including
Coupling type earthing clamp, reverse drawing bar, spring storehouse, spring, the reverse drawing bar are arranged in spring storehouse, and reverse drawing bar upper end from
The storehouse lid centre bore of spring storehouse upper end is stretched out, and the spring is arranged in spring storehouse while being enclosed within reverse drawing bar, the reverse drawing bar
Upper end is hinged with coupling type earthing clamp bottom.
The reverse drawing bar bottom sets a chassis, and the spring bottom end is withstood on chassis, and spring top withstands on spring storehouse
Storehouse interior surface, the spring upper end external diameter be more than storehouse lid centre bore aperture, lower spring end external diameter be less than chassis external diameter.
The reverse drawing bar upper end is hinged by bearing pin with coupling type earthing clamp bottom.
The coupling type earthing clamp bottom inner side sets support inner sleeve, and the support inner sleeve is again by bearing pin and reverse drawing
Bar is hinged, and the support inner sleeve is contacted with spring Cang Shangduancang lids.
Housing is cased with outside the spring storehouse, housing upper end is not higher than Cang Gai.
Compared to prior art, the utility model has the advantages that：
Adjustable multi-angle drop bar is novel in design, easy to operate, is adapted in electric substation various electric with power circuit
Installing ground wire is used during equipment wire vertical arrangement arrangement.After using the drop bar, the safe and reliable of work is ensure that conscientiously
Property, operating efficiency is significantly improved, maintenance and fault handling time are shortened, it is that enterprise has saved cost, achieve good
Economic benefit and social benefit.

Specific embodiment
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides ginseng
Examine and purposes of discussion, not for being any limitation as to the utility model.
According to Fig. 1-6, adjustable multi-angle drop bar, including coupling type earthing clamp 1, reverse drawing bar 3, spring storehouse, spring
4, the reverse drawing bar 3 is arranged in spring storehouse, and the upper end of reverse drawing bar is stretched out from the storehouse lid centre bore of spring storehouse upper end, described
Spring 4 is arranged in spring storehouse while being enclosed within reverse drawing bar 3, the reverse drawing bar upper end is hinged with coupling type earthing clamp bottom.
The reverse drawing bar bottom sets a chassis, and the spring bottom end is withstood on chassis, and spring top is withstood in the storehouse lid in spring storehouse
Surface, the spring upper end external diameter is more than storehouse lid centre bore aperture, and lower spring end external diameter is less than chassis external diameter.The reverse drawing bar 3
Upper end is hinged by bearing pin 2 with coupling type earthing clamp bottom.The coupling type earthing clamp bottom inner side sets support inner sleeve,
The support inner sleeve is hinged again by bearing pin with reverse drawing bar, and the support inner sleeve is contacted with spring Cang Shangduancang lids.The bullet
Housing 5 is cased with outside spring storehouse, housing upper end is not higher than Cang Gai.
A notch is processed into the end of common metal coupling type earthing clamp, in a kind of metal elastic of drop bar head design
Spring storehouse, on reverse drawing bar, tongue structure part bottom has an anti-avulsion cylindrical to spring housing, and its external diameter is equal to spring outer diameter, spring silo roof
Portion is provided with the otch matched with tongue structure part top, is formed and is flexibly connected, tongue structure part end insertion earthing clamp
Notch, both are coordinated by gap, are respectively equipped with pin-and-hole on tongue structure part top and notch center line and install pin,
Make to consistently form a steering positioning lock at tongue structure part end and earthing clamp end notch under the reaction of spring mechanism
Clamp force square, to prevent from loosening.The angle for making drop bar and earthing clamp by the utility model structure can freely become between 0-90 °
Change.
Working method is hinged by bearing pin 2 for the bottom of the earthing clamp 1 with the upper end of reverse drawing bar 3, reverse drawing bar 3, spring 4,
Housing 5 coordinates makes reverse drawing bar 3 produce a reaction pulling force, for the bottom of positioning both ground wire clamp 1.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the scope of the claims of the present utility model, its
He all should all belong to the scope of the claims of the present utility model with the equivalence changes of patent spirit of the present utility model.
