Description

A kind of upside-down mounting wire-clamp-type insulation tractor
Technical field
The utility model relates to a kind of for 66 KV transmission line charged adjustment degree of speeding or a complete set of gold utensil of replacing insulator under electrified head and power failure degree of tightness wire upside-down mounting wire clamp insulation used tractor.
Background technology
Electric power is the important foundation industry of national economy and social development, along with the development of economic society, to the degree of dependence of supply of electric power more and more by force, more and more higher to the requirement of power supply reliability, the economic loss that power outage causes is also increasing for national economy and the lives of the people.Electric power safety is concerning economic overall situation and the lives of the people, and any accident, all may bring the loss that cannot retrieve to society, particularly electric grid large area power cut accident, and the harm cause society and impact are difficult to estimate.As the social responsibility of power department, the stabilization of power grids to be safeguarded exactly with all strength, ensure social stability, electric power netting safe running is put in the first place.But accident, danger comprise the impact of force majeure, these are all not predictable, so electric grid large area power cut crisis still exists.
In conventional transmission lines road adjustment degree of speeding and the work changing a complete set of gold utensil of insulation head, owing to not designing rational method and instrument, power failure operation can only be adopted, to the above-mentioned harm that life and economy bring, power failure requires that power department carries out live line working in the process changing gold utensil, and live line working is very unsafe to workmen.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of and effectively solves for flip-over type strain clamp insulation tractor power failure operation is turned shape to live line working, effectively avoids induced electricity to hurt sb.'s feelings and facilitates the problem of special pole tower operation etc.
The utility model realizes like this, a kind of upside-down mounting wire-clamp-type insulation tractor, described tractor comprises arm-tie and head, adopt insulation pulling plate as main traction and mounting rod, the two ends of arm-tie are respectively conductor wire end and tower head end, described tower head end has installing hole and reliably connects for high-strength insulating pull rope, described conductor wire end and head are bolted, described head comprises both sides steel plate, the centre of both sides steel plate is fixed U-shaped connector and is connected with conductor wire end, the lower end of both sides steel plate respectively has a lockhole, once bayonet lock nail penetrates both sides lockhole smoothly.
Further, one end of described lower bayonet lock nail be circular arc type, and the tail end that lower bayonet lock is followed closely is equipped with little link to the convenient lockhole inserting opposite, and the steel plate that the tail end followed closely at lower bayonet lock exposes arranges slideway, and little link is flexibly connected with slideway.
Further, described slideway is two and parallelly has common port track structure, and on described slideway welding steel, the little link making lower bayonet lock follow closely tail end is free to slide in slideway, plays and makes lower bayonet lock follow closely the parallel effect penetrated in the lockhole of opposite.
Compared with prior art, beneficial effect is the utility model:
The utility model can make the work change of power failure be hot line job, improves amount of power supply and reliability; Protect staff by faradic injury to greatest extent, improve fail safe; Power failure operation avoids staff and climbs out of installation, the physical demands of the personnel of reduction; Power failure operation saves the activity duration, improves the completion rate of work; The convenient operation of work of the lastex of special type shaft tower and serious declivity.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of upside-down mounting wire-clamp-type insulation tractor, described tractor comprises arm-tie 1 and head 4, described arm-tie 1 is insulation pulling plate, adopt insulation pulling plate as main traction and mounting rod, the two ends of arm-tie 1 are respectively conductor wire end 3 and tower head end 2, described tower head end 2 has installing hole 6 and reliably connects for high-strength insulating pull rope, described conductor wire end 3 is bolted with head 4, described head 4 comprises both sides steel plate, the centre of both sides steel plate is fixed U-shaped connector 5 and is connected with conductor wire end 3, the lower end of both sides steel plate respectively there is a lockhole, once bayonet lock nail 8 penetrates both sides lockhole smoothly.
One end of lower bayonet lock nail 8 be circular arc type, the convenient lockhole inserting opposite, and the tail end that lower bayonet lock follows closely 8 is equipped with little link 9, and the steel plate that the tail end followed closely at lower bayonet lock exposes arranges slideway 7, and little link 9 is flexibly connected with slideway 7.Slideway 7 is two and parallelly has common port track structure, and on slideway 7 welding steel, the little link 9 making lower bayonet lock follow closely tail end is free to slide in slideway 7, plays and makes lower bayonet lock follow closely the parallel effect penetrated in the lockhole of opposite.
Tractor head 4 ride drop on upside-down mounting wire clamp time, when tilting a little, lower bayonet lock nail 8 can slide in the lockhole on opposite automatically, blocks wire clamp after tension, and the lower bayonet lock nail 8 that again tilts after end-of-job can skid off automatically.The front end of lower bayonet lock nail 8 is circular arc type design, the convenient lockhole inserting opposite, above the tail end of lower bayonet lock nail, little link 9 is housed to be flexibly connected with slideway 7, just as the meaning of common lock headgear in safety pin, slideway is welded on the steel plate of tractor head, just as safety pin erects the meaning of two cushions in tractor head steel plate, the little link making lower bayonet lock follow closely tail end is free to slide in slideway, play and make lower bayonet lock follow closely the parallel effect penetrated in the lockhole of opposite, align with steel plate nexine to play and do not affect head and ride and drop on upside-down mounting wire clamp in lower bayonet lock nail its front end when opening, the circular arc portion of lower bayonet lock nail its front end when closing all stretches out outside the lockhole of opposite, object ensures that pulling force is born in the maximum cross-section of pin, be unlikely to make lower bayonet lock follow closely distortion.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
