Description
Technical field
Tested the present invention relates to a kind of power equipment breaker p-wire Special hanging bonding tool, more particularly to a kind of breaker
Line hitch bar.
Background technology
When now carrying out characteristic test to breaker, typically using two methods, one kind is p-wire using artificial extension of ascending a height
The method connect.Such as ascended a height using ladder, security risk is high, it is necessary to ascend a height when especially to the progress characteristic test of 220kV breakers
More than 6 meters, easily occur high fall accident, at least need 3 operating personnels.Lift truck is such as used, 3 operation people are at least needed
Member is, it is necessary to which lift truck at least movement three times, add working strength.Bucket arm vehicle is such as used, also needs to consider the operation ring of bucket arm vehicle
Border, some positions, bucket arm vehicle can not also be reached, and also improve operating cost.
Second method is the high-altitude standard trolley using high-potting, although mounting p-wire not using high-altitude standard trolley
Need to manually it ascend a height, but high-altitude standard trolley does not aim at circuit breaker characteristic experiment extension p-wire and used, and general body of rod weight is big, makes
Insulating bar joint number is more, needs at least 9 insulating bars to hang p-wire by taking the fracture breakers of 220kV six as an example, cumbersome.
So needing a kind of special to complete the instrument that p-wire is mounted without ascend a height.
The content of the invention
The present invention can complete p-wire mounting there is provided that can not ascend a height for above-mentioned problems of the prior art
Instrument.Solve the problem of mounting of prior art p-wire is dangerous, inconvenient.
Technical scheme is as follows：
Breaker p-wire hitch bar, includes chuck and action bars, in the jack on described chuck insertion operation bar top；Institute
The chuck stated includes clamp head, dynamic chuck and moveable combination of guide rod, clamp head generally 7 types, and its bottom is connected with moveable combination of guide rod, dynamic
Chuck is arranged on the middle part of clamp head and be arranged in parallel with the top of clamp head, is provided with fixed pulley on clamp head, is driven steel wire
One end of rope is connected on dynamic chuck, and the other end is bypassed and is connected to after fixed pulley in moveable combination of guide rod.
In the jack on the described action bars top and bottom of moveable combination of guide rod is provided with strong magnetic piece.
The described clamp head side corresponding with dynamic chuck is provided with pointed tooth.
In described clamp head holddown spring is provided with the top of pointed tooth.
Positioning ball is provided with the position that the bottom of described clamp head matches with moveable combination of guide rod.
One end that described shackle line is connected with moveable combination of guide rod is provided with driving spring.
The slideway that convenient dynamic chuck is slided is provided with described clamp head.
Advantage for present invention is with beneficial effect：
Upward motion of the present invention by moving chuck coordinates with clamp head clamps breaker wire guide plate, utilizes steel wire rope and dynamic chuck
Frictional force chuck is maintained at step up state.Described operation boom end is designed using horn mouth, built-in strong magnetic piece, convenient pair
Connect.Lightweight, sound construction of the invention, chuck, which steps up rear any vibrations, will not make chuck come off, and convenient disassembly is thoroughly solved
P-wire unsafe problem is mounted when circuit breaker characteristic is tested.The present invention is that one kind aims at breaker progress acting characteristic test
When the special hitch bar that uses of mounting p-wire, with it is safe, easy to use, save the effect of activity duration.
Brief description of the drawings
Fig. 1 is open mode structural representation of the invention.
Fig. 2 steps up status architecture schematic diagram for the present invention's.
In figure：Chuck 1, action bars 2, strong magnetic piece 3, clamp first 4, moveable combination of guide rod 5, shackle line 6, fixed pulley 7 moves folder
First 8, slideway 9, holddown spring 10, pointed tooth 11, driving spring 12, final position 13, positioning ball 14, binding post 15, friction connects
Contacting surface 16.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As indicated with 1, breaker p-wire hitch bar, includes chuck 1 and action bars 2, the described insertion operation bar top of chuck 1
Jack in；Described chuck includes clamp first 4, dynamic chuck 8 and moveable combination of guide rod 5, generally 7 types of clamp first 4, its bottom with
Moveable combination of guide rod is connected, dynamic chuck 8 is arranged on the middle part of clamp head and is be arranged in parallel with the top of clamp head, is provided with clamp head
Fixed pulley 7, one end of shackle line 6 is connected on dynamic chuck, and the other end is connected to after bypassing fixed pulley, frictional contact surface 16
In moveable combination of guide rod.Binding post 15 is arranged on the top of clamp head.
In the jack on the described action bars top and bottom of moveable combination of guide rod 5 is provided with strong magnetic piece 3.
The described clamp head side corresponding with dynamic chuck is provided with pointed tooth 11.
In described clamp head holddown spring 10 is provided with the top of pointed tooth.
Positioning ball 14 is provided with the position that the bottom of described clamp head matches with moveable combination of guide rod.
One end that described shackle line is connected with moveable combination of guide rod is provided with driving spring 12.
The slideway 9 that convenient dynamic chuck is slided is provided with described clamp head.
As shown in Figure 1, 2, the course of work of the invention is as follows：
Chuck is in open mode, by the top of 1 insertion operation bar of chuck 2, because insertion site has strong magnetic piece 3, is pressed from both sides during mounting
Head will not fall off；Clamp first 4 is hung on wire connection board of circuit breaker during mounting, action bars 2 is pulled downward on, in the suction band of strong magnetic piece 3
Dynamic lower moveable combination of guide rod 5 is moved downward, and pulls shackle line 6 also to move downward, the steering that shackle line 6 passes through fixed pulley 7
Make the dynamic chuck 8 of traction to move upwards along slideway 9, close to clamp first 4, wire connection board of circuit breaker is clamped, while the pressure in clamp first 4
Tight spring 10 is compressed, further high clamping force, and the oxide layer that the pointed tooth 11 on dynamic and static chuck can be broken in device junction makes
Test linear contact lay good；After dynamic chuck 8, which is moved, can not move upwards again in place, shackle line 6, which continues to move downward, to be passed
Spring 12 of moving is stretched, and the position 13 until moveable combination of guide rod 5 is reached home, positioning ball 14 blocks moveable combination of guide rod 5, it is ensured that activity is led
Bar 5 will not loosen, and continue pulling operation bar 1 until being separated with chuck 2, complete mounting, p-wire is screwed in the wiring on quiet chuck
On post 15.
Because the spring in moveable combination of guide rod is stretched, the stress all the time of steel wire rope 4 can be made, the afterbody of dynamic chuck withstands on steel wire rope
The afterbody of upper formation frictional contact surface 16, the steel wire rope of stress and dynamic chuck has very big frictional force to make chuck 1 is firm to be clipped in
On wire connection board of circuit breaker.
When removing chuck 1, by the bottom of 2 top alignment moveable combination of guide rod of action bars 5, strong magnetic piece 3 is attracted each other, and work is pushed away in continuation
Dynamic guide rod 5, loosens driving spring 12, declines the frictional force between the afterbody of steel wire rope 6 and dynamic chuck 8, while dynamic chuck 8 is being pushed away
Moved downward under power effect, you can remove chuck 1.
The present invention can easily mount p-wire, according to how much determinations of breaker fracture when circuit breaker characteristic is tested
The chuck quantity used, can be completed during mounting using same action bars, improve the level of security of field operation, save man-hour
And manpower, obtain the extensive favorable comment of operating personnel.
