Description
Technical field
The utility model belongs to electric power system O＆M service kit correlative technology field, more particularly to a kind of laborsaving yielding formula
Double tongue earth wire operation sticks.
Background technology
Short-circuit grounding wire must be installed in power transmission lines overhauling, it is to utilize ground connection to mount and dismount short-circuit grounding wire at present
Line operation stick is operated.General earth wire operation stick is made of insulating bar, clamp for ground wire and connector, and connector is
Tubulose, clamp for ground wire are inserted into the upper end, and insulating bar is inserted into its lower end, and the common form of clamp for ground wire has spiral to fix
Formula, single tongue formula and double tongue type, these types of earth wire operation stick all have some disadvantages：The 1st, although the fixed clamping of spiral is steady
It is fixed, but the troublesome in poeration and time is long, and also long-time service rear screw bar gets rusty easily；2nd, single tongue formula and double tongue type ground wire are hung
Although hook operation it is simpler, when clamp for ground wire sandwiches conducting wire, the tongue piece on hook be not easy shrink, it is necessary to using compared with
Big strength could complete wired earth, there are security risk after long-time operation, and cannot meet the use need of different occasions
It asks.
Utility model content
The utility model overcomes the prior art to be grounded stick operating cost for problem present in above-mentioned earth wire operation stick
The problem of power, drop bar is not easy to separate with conducting wire, provides a kind of improvement rational in infrastructure, time saving and energy saving, protection personal safety
The double tongue drop bars of the quick detachable easy take-up of type.
The utility model is by solving the problems, such as above-mentioned adopt the technical scheme that：A kind of double whip grafts of laborsaving yielding formula
Ground wire operation stick including insulating bar, clamp for ground wire and connecting tube, is fixedly installed on the inside of the cantilever end of the clamp for ground wire
First tongue piece, the fixing end inside of the clamp for ground wire are connected with the second tongue by the symmetrically arranged yielding slot that slides
Piece, second tongue piece are connected with the bracing wire one end for penetrating clamp for ground wire and insulating bar by adjustable spring, bracing wire it is another
End connection is arranged on the lifting rod in insulating bar Handheld Division, is provided with refrative cavity on insulating bar Handheld Division, on the lifting rod
The first rotation loose joint, the second rotation loose joint and folding rod are provided with, the first rotation loose joint is fixed on the inside of insulating bar, the second rotation
It turns a work and connects lifting rod and folding rod in succession.
Further, first tongue piece and the second tongue piece are arc-shaped.
The beneficial effects of the utility model are：Compared with prior art, 1, pass through to set to make a concession on the tongue piece of one side and slide
Slot so that during hook clamping conducting wire, tongue piece, which slides, reduces reversal of stress, is more prone to operate, time saving and energy saving；2nd, folding rod can revolve
Turnover is folded, compared to existing handle and rotation handle, greatly reduces operation stick and occupies volume, earth wire operation stick not rapid wear
It is bad.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model drop bar,
Fig. 2 is the X-X enlarged structure schematic diagrams of Fig. 1.
In the figure 1, cantilever end 2, the second tongue piece 3, clamp for ground wire 4, adjustable spring 5, fixing end 6,
One tongue piece 7 slides and makes a concession slot 8, connecting tube 9, bracing wire 10, insulating bar 11, ground lead 12, Handheld Division
13rd, refrative cavity 14, first rotates loose joint 15, lifting rod 16, second rotates loose joint 17, folding rod 18, conducting wire.
Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, below in conjunction with the accompanying drawings to this reality
With new further explanation.
As shown in Figure 1, 2, the double tongue earth wire operation sticks of a kind of laborsaving yielding formula, including insulating bar 10（It can more piece spelling
It connects）, clamp for ground wire 3（It is made of pack alloy）With connecting tube 8, ground lead 11 is further included certainly, and the ground wire is hung
1 inside of cantilever end of hook is fixedly installed the first tongue piece 6, and 5 inside of fixing end of the clamp for ground wire is by symmetrically arranged
It slides yielding slot 7 and is connected with the second tongue piece 2（The shape for sliding yielding slot can be various shapes, preferably horizontal linear
Slot because the tongue piece used at present is Steel material, stress substantially will not deformation, the second tongue piece when stress, reduce resistance
Power, can be with rapid horizontal）, second tongue piece is connected with by adjustable spring 4 penetrates clamp for ground wire and insulating bar
9 one end of bracing wire, the other end connection of bracing wire are arranged on the lifting rod 15 in insulating bar Handheld Division 12, and insulating bar is set on Handheld Division
Refrative cavity 13 is equipped with, is provided with the first rotation loose joint 14, second rotation loose joint 16 and folding rod 17 on the lifting rod, first
Rotation loose joint is fixed on the inside of insulating bar, the second rotation loose joint connection lifting rod and folding rod（Second loose joint is arranged to can only be single
To being folded up, specific form can set limited block in the lower end junction of lifting rod and folding rod, so may be such that folding
The rotating range of folded bar is 0 to 90 degree, and at 90 degree, folding rod 17 can be reset in refrative cavity, can be into horizontal at 0 degree
State）, in above-mentioned, insulating bar and Handheld Division and lifting rod and the strong fibrous epoxy resin system of the preferred insulation performance of folding rod
Into.
Preferably, in order to more laborsaving in operation, first tongue piece and the second tongue piece are arc-shaped.
Ground lead on earthing clamp when mounted, is grounded by the utility model first, then by clamp for ground wire with leading
Line 18 contacts, you can completes installation.
In dismounting, folding rod is rotated out of out of refrative cavity, firmly presses down on folding rod, pass through the first rotation loose joint
Be rotated down, drive bracing wire move down, adjustable spring is shunk to the right, and further pull on the second tongue piece slide make a concession slot
There is gap in interior slip between the first tongue piece and the second tongue piece, conducting wire with the first tongue piece, the second tongue piece it is possible thereby to smoothly divide
From.Then the down force on folding rod is removed, spring can promote the second tongue piece to be moved to the left due to the elasticity of itself,
Until being in contact with the first scotia tablet.
Embodiment of above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to specific embodiment
The utility model is described in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the utility model
Art scheme is modified or replaced equivalently, and without departing from the spirit and scope of technical solutions of the utility model, should all be covered
In the protective scope of the claims of the utility model.
