Description
Technical field
The present invention relates to power line earthing or grounding means, and in particular to a kind of grounding wire clamp apparatus.
Background technology
Overhead power line ensures the safety of staff in interruption maintenance, it is desirable that power failure operation circuit with connect
Ground wire is hung up between earth polar, to prevent unexpected power transmission and induced electricity from bringing danger to staff.China's electric system at present
There are mainly two types of structures for used grounding wire clamp apparatus, and one is by leaf spring clamping mode, another kind is to be fastened by bolts
Clamping mode, both grounding wire clamp apparatus all exist the defect less reliable with the contact effect between overhead line, cause to hang
The connection between overhead transmission line and earthing pole after ground wire is less reliable, it may occur that is arrived due to being grounded unreliable induced electricity electric shock
The accident of staff brings unnecessary danger.In order to avoid the generation of dangerous situation, it is sometimes desirable to hang multigroup ground wire and come
Increase the reliability of ground connection, this brings many unnecessary troubles to inspection operation again.There is also not sides for existing grounding wire clamp apparatus
Just the defect for being suspended on overhead line and being taken off from overhead line is unfavorable for shortening the interruption maintenance time and improves operating speed,
Influence whether normal power supply.
Invention content

The hook of ceases to be busy hanging groove, position opposite below overhead line hanging groove is equipped with slide opening, movable fixture along the vertical direction on holding clamp
Lower part be the slide bar slided up and down in slide opening, the upper end of slide bar be equipped with positioned at slide opening and hook between movable fixture
Head, movable fixture head are equipped with the overhead line clamping slot with the overhead line hanging groove relative engagement on holding clamp upwards, active card
Have head and be equipped with the outside for linking up with mated position with the matched draw ring of operating lever pull rod, be equipped in slide opening and be sleeved on slide bar
Compression spring one, the upper end of compression spring one is matched with slide bar, lower end matches with holding clamp and forms upper elasticity to movable fixture, Gu
The lower end for determining to be equipped with below fixture upper end and holding clamp is fixedly linked and connector sleeve of the sliding sleeve outside slide bar, fixing card
Have and enclose several steel ball holes circumferentially arranged with one on the connector sleeve side wall of lower section, it is big to be separately installed with a diameter in each steel ball hole
In the steel ball of connector sleeve sidewall thickness, the slide bar outer wall being slidingly fitted with position of the connector sleeve equipped with steel ball hole is equipped with a circle
With the matched annular steel bead groove of each steel ball, the lower section of holding clamp is equipped with control set of the sliding sleeve outside connector sleeve, control
It is to be slided with connector sleeve outer wall that the upper end endoporus of system set, which is with the lower section of the matched large diameter hole one of each steel ball, large diameter hole one,
The small diameter bore of dynamic cooperation, the control set inner wall between large diameter hole one and small diameter bore is the up big and down small guiding conical surface, small
Control set endoporus below diametric hole is the large diameter hole two that internal diameter is more than small diameter bore, and the company of being sleeved on is equipped in large diameter hole two
Compression spring two outside female connector, the lower end of connector sleeve are equipped with the large diameter hole two that outer wall is covered with control and are slidingly fitted and fix peace
End cap outside connector sleeve lower end, the control set inner face of two top of the upper end of compression spring two and large diameter hole matches, under
End is matched with the upper surface of end cap.
The solution have the advantages that：It can guarantee and contacted between grounding wire clamp apparatus and overhead line reliably using it, dislodging connects
Convenient ground wire is quick, is conducive to shorten the interruption maintenance time and improves operating speed, does not interfere with normal power supply.It is operated with
Convenient, service speed is fast, and operating method is simple, only needs pull joystick to hold it securely tightly after being suspended on overhead line
It on overhead line, is contacted between overhead line solid and reliable, and swing and sliding will not be generated on overhead line, be conducive to reliable
Ground connection.It only needs to pull grounding wire clamp apparatus to open on overhead line with operating lever when taking from overhead line, so that it may with easily
It is taken off from overhead line, it, which can effectively save to set out, holds the time of ground wire, operates quick, safe and reliable and square
Just.

On annular steel bead groove 26 be locked in and the 41 matched position of each steel ball hole on connector sleeve 4, active card by each steel ball 42
Tool 2 is lockked by control set 5 without automatic bullet loading.
It is covered on 5 using control is sleeved on from bottom to top mounted on the operation head 7 of operating lever front end, and keeps operation head 7 thick
Each open slot 73 on cylinder 71 is matched with each raised 55 on control set 5, and upper act operating lever drives grounding wire clamp apparatus and ground connection
Line rises to overhead line height, and the opening between hook 12 and movable fixture head 22 is made to be directed at overhead line and make the frame on hook 12
Ceases to be busy hanging groove 11 is hung on overhead line.
Rotation process bar makes the swivelling chute 74 in operation head 7 match with each raised 55 on control set 5 and merges card downwards
Firmly each raised 55, pulling operation bar, control 5 compression press springs 2 43 of set glide, each steel ball 42 from the small diameter bore 52 of control set 5 into
Enter bullet inside and outside large diameter hole 1 and axial lock no longer is played to slide bar 21, movable fixture 2 can be in the work of compression spring 1
With lower automatic bullet loading, the overhead line clamping slot 23 on movable fixture head 22 is made to be embraced together with the overhead line hanging groove 11 on hook 12
Overhead line keeps ground connection reliably secure to which grounding wire clamp apparatus to be securely attached on overhead line.
After hanging up properly ground wire, reverse turn operation bar, lower pumping operation head 7 makes operation head 7 be disengaged with control set 5, operating lever
It can be detached from and be opened on ground with grounding wire clamp apparatus.
When plucking ground wire the draw ring 24 on movable fixture head 22, pulling operation are inserted into using the pull rod 75 in operation head 7
Bar, so that it may so that movable fixture 2 and its slide bar 21 glide, movable fixture 2 is lockked by control set 5 without automatic bullet loading again,
Grounding wire clamp apparatus is opened, and operating lever is above chosen, so that it may to take off grounding wire clamp apparatus from overhead line, it is complete to pluck ground connection line process
At.
By above-mentioned application method as it can be seen that this grounding wire clamp apparatus hang, pluck ground wire it is quick, flexible and reliable, operate with
It is very convenient.
