Abstract

The utility model discloses a bracing frame for replacing a vibration damper. The bracing frame comprises three length-adjustable support bars which are connected and hinged to a same connecting block, and a bayonet joint for plugging an insulated operating lever is arranged on the upper end of the connecting block. The bayonet joint is a universal joint connected to the connecting block, and the lower end of each support bar is provided with a hook hinged to the support bar. The lengths of the three legs of the bracing frame are adjustable, and a hook on the lower end of each support bar can be attached to different towers and poles. The bayonet joint on the connecting block can be used for assembly of insulation bars different in size and is rotatable and detachable. The bracing frame is portable and practical, substantially reduces operation difficulty of a operating lever for ground-potential work based on the lever principle. The labor intensity for replacing a vibration damper is substantially reduced.

Description

A kind of replacing stockbridge damper bracing frame
Technical field
The utility model relates to a kind of replacing stockbridge damper equipment, particularly a kind of replacing stockbridge damper bracing frame.
Background technology
As the indispensable gold utensil of overhead transmission line, stockbridge damper is widely used in all circuit paragraphs.The problems such as its damage, displacement are one of FAQs of circuit, the phenomenon such as impaired or displacement for stockbridge damper, if all apply for, interruption maintenance will reduce grid stability, also can affect supply of electric power simultaneously, if but wait power failure chance to change again and will certainly strengthen line security hidden danger, the reduction circuit general level of the health, therefore for the best solution of problems, be to adopt charged mode to carry out in time defect elimination processing, guarantee that line security is stable.
The master operation of changing stockbridge damper operation requires operation finer and smoother, and conventional earth potential working instrument cannot meet its job requirements, reaches operation object.Therefore, various places generally adopt equal potential working mode at present, enter electric field equipotential carry out upkeep operation by operating personnel.But equal potential working security risk is larger, very strict for persons' composition gap, operation gap requirement to this " safety ", on the tower of a lot of little spaces, (take 110kV and following tower as main) and often cannot meet job requirements.Thereby causing changing operation cannot complete in time.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of a kind of replacing stockbridge damper support applicable to charged for replacement stockbridge damper is provided.
A kind of replacing stockbridge damper support, include the support bar of the adjustable length of 3, the support bar of 3 is connected on a contiguous block, the support bar of three is hinged on contiguous block, in the upper end of contiguous block, be provided with the connection-peg for the insulating bar of pegging graft, described connection-peg, for to be connected on contiguous block by universal joint, is provided with a grapple in the bottom of every support bar, and described grapple is hinged on support bar.
The replacing stockbridge damper support of this structure, in use, the support bar of three is hooked in respectively on pylon, up square neck is oblique with support to make to change stockbridge damper, then insulating bar bar is plugged on connection-peg, and stockbridge damper grapple is arranged on to the head of insulating bar, just can realize the replacing of stockbridge damper, adopt replacing stockbridge damper of the present utility model can realize earthy safety work with support, can alleviate again the labour intensity of changing stockbridge damper.
Hinged between hinged, grapple between described support bar and contiguous block and support bar is detachable hinged.
Adopt detachable being hinged on while not needing to use, can, by this support dismounting packing, be convenient to deposit and carry.
Described grapple includes two snatch pin that become 90 degree, is provided with screw thread, on snatch pin, is provided with compressing tablet and a locking nut of a L-type on the snatch pin of every, and compressing tablet and locking nut can move on snatch pin.
The grapple of this structure, utilizes two to become the crooked angle bar of the snatch pin of 90 degree and 90 degree of shaft tower tower material to fasten, then with compressing tablet and locking nut locking.
The support bar of described adjustable length, for support bar is consisted of mutual sheathing inside and outside two pipe fittings together, is provided with through hole in a row along its axis direction on inside and outside two pipe fittings, with connector, they is locked after adjusting as required relative length.
The length of three support bars of length adjustment of bracing frame is as required to adapt to the on-the-spot needs that use in use.
Described connection-peg is the connection-peg of hood type.
In sum, the utility model following advantage compared to existing technology:
Replacing stockbridge damper support of the present utility model, its tripod length is adjustable, hook is set in the bottom of every support bar can grab the connection-peg being attached on different shaft tower tower equipment structures, on contiguous block and can carry different model insulating bar and rotatable, dismounting; The light practicality of this bracing frame, by lever principle, greatly reduces earth potential working action bars operation easier.And can greatly reduce the working strength of changing stockbridge damper.
Accompanying drawing explanation
Fig. 1 is the structural representation of bracing frame for replacing stockbridge damper of the present utility model.
Label declaration 1 support bar 2 contiguous block 3 connection-peg 4 grapple 41 snatch pin 42 compressing tablet 43 locking nuts.
Embodiment
Below in conjunction with embodiment, the utility model is described in more detail.
Embodiment 1
A kind of replacing stockbridge damper support as shown in Figure 1, include the support bar 1 of the adjustable length of 3, the support bar of 3 is connected on a contiguous block 2, the support bar of three is hinged on contiguous block, in the upper end of contiguous block, be provided with the connection-peg 3 for the insulating bar of pegging graft, described connection-peg, for to be connected on contiguous block by universal joint, is provided with a grapple 4 in the bottom of every support bar, described grapple is hinged on support bar.Hinged between hinged, grapple between described support bar and contiguous block and support bar is detachable hinged.Described grapple includes two snatch pin 41 that become 90 degree, is provided with screw thread, on snatch pin, is provided with compressing tablet 42 and a locking nut 43 of a L-type on the snatch pin of every, and compressing tablet and locking nut can move on snatch pin.The support bar of described adjustable length, for support bar is consisted of mutual sheathing inside and outside two pipe fittings together, is provided with through hole in a row along its axis direction on inside and outside two pipe fittings, with connector, they is locked after adjusting as required relative length.
It is same as the prior art that the present embodiment is not stated part.
