Description
Technical field
The present invention relates to a kind of scalable multi-steering line-to-ground lines for power engineering field.
Background technique
During 10kV distribution operation and maintenance, caused by overhead transmission line hanging earthing conductor can prevent job site from sending a telegram here suddenly
Personal injury is an important technical measures for electric safety in Phase of Electric Power Projects.Electric operating is live both at home and abroad at present
Common 10kV line-to-ground line is all largely that insulating bar is non-telescoping, the indeflectible general type ground line of grounding head.
It has the following disadvantages: (1) insulation pole length is inadequate in the ground connection higher situation of site location, if mounted by force, makees
The safe distance at industry personnel's distance electrification position not can guarantee, this situation can be brought great potential safety hazard, and also will increase operation
The operation intensity of personnel, extension wire power off time.(2) on the other hand, it sometimes needs on operating mechanism lead pile crown
Hanging earthing conductor, conventional ground line flat mouth connector is inconvenient for use, and it is firm to mount or mount, this normal inspection to route
It repairs and will also result in security risk.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of scalable multi-steering line-to-ground line,
It can be realized ground line easily mounting.
Realize above-mentioned purpose a kind of technical solution be: a kind of scalable multi-steering line-to-ground line, including insulating bar and
Grounding head further includes angular stop means,
The insulating bar is the Telescopic rod structure that the body of rod being mutually socketed is formed；
The grounding head is arranged in the end of the insulating bar, and the grounding head is hollow gimbal structure, and described ten thousand
The end of the insulating bar is socketed in a section of section, another section of the universal joint is connect with the angular stop means；
The angular stop means include wire clamp framework, wire clamp screw rod and wire clamp active tongue component；The wire clamp framework
Bottom offers connecting hole, and the wire clamp framework is socketed on the wire clamp screw rod by connecting hole；The wire clamp screw rod and institute
State universal joint threaded connection；The wire clamp active tongue component includes active tongue and gag lever post, and the gag lever post is arranged in universal joint
On, the active tongue is fixed on the wire clamp screw rod, and the tail portion of the active tongue is curved slot arrangement, the arc groove socket
It is limited outside the gag lever post, and through wing nut.
Further, it is offered in the wire clamp framework and links up with the fixation hole.
Further, wire clamp slot is offered on the inside of the wire clamp framework.
A kind of scalable multi-steering line-to-ground line of the invention changes the length of insulating bar by stretch mode；Pass through
The steering for changing grounding head changes the connection direction of ground line, and grounding head is combined using hollow universal joint and angular stop means
Structure, after hollow universal joint ensure that angulation change, grounding head still be able to by rotate insulating bar transmission force effect, from
And promote and pull open active tongue, angular stop means ensure that steering angle variation range is unlikely to too large or too small.

Specific embodiment
In order to preferably understand technical solution of the present invention, below by specifically embodiment and in conjunction with attached drawing
It is described in detail:
Referring to Fig. 1, a kind of scalable multi-steering line-to-ground line of the invention, including insulating bar 1, grounding head 2 and angle
Spend limiting device 3.
Insulating bar 1 is the Telescopic rod structure that the body of rod being mutually socketed is formed.Limit button 11 and limit are equipped on insulating bar
Hole 12, the length adjustment by that can carry out insulating bar 1 by lower limit button 11 is turned round until limit to be clamped into next limit hole 12.Absolutely
The telescopic extensions of edge bar 1 are 1033~1513mm, the material epoxy resin color tube of insulating bar 1.
Please referring to Fig. 2 and Fig. 3, grounding head 2 is arranged in the end of insulating bar 1, and grounding head is hollow gimbal structure, and ten thousand
The end of insulating bar is socketed in a section of section, another section of universal joint is connect with angular stop means 3.Hollow universal joint is protected
After having demonstrate,proved angulation change, grounding head still is able to the effect by rotating insulating bar transmission force, to promote and pull open wire clamp tongue
Head
Angular stop means 3 include wire clamp framework 31, wire clamp screw rod 32 and wire clamp active tongue component.The bottom of wire clamp framework 31
Portion offers connecting hole, and wire clamp framework 31 is socketed on wire clamp screw rod 32 by connecting hole.Wire clamp screw rod 32 and universal joint screw thread
Connection.Wire clamp active tongue component includes active tongue 33 and gag lever post 34, and gag lever post 34 is arranged on universal joint, and active tongue 33 is fixed
On wire clamp screw rod 32, the tail portion of active tongue 33 is 35 structure of arc groove, and arc groove 35 is socketed in outside gag lever post 34, and passes through butterfly
The limit of shape nut.Since the transmission of power needs to carry out in specific angular range, when grounding head 2 is vertical with insulating bar 1 or
Close to it is vertical when, rotating insulated bar cannot make grounding head tongue transfer, grounding head can not be tightened, so needing to limit by angle
Position device 3 limits the rotational angle of grounding head, and limited angular range is determined as -45 °~45 ° by actual measurement.
It is offered in wire clamp framework and links up with the fixation hole 4, carry out mounting fixation, the inside of wire clamp framework to earth wire
Wire clamp slot is offered, to clamp pile crown 5.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
