Description

A kind of two insulator string 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 used pair of insulator string insulation 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 the tractor of two insulator string insulation targetedly, effectively solves and 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 two insulator string insulation tractor, described tractor comprises arm-tie, connector and is connected to two link plates on connector, described connector is the structure with intermediate gaps that upper and lower equilateral triangle connecting plate is connected to form as axle by the bolt at three angles, one end of described arm-tie is flexibly connected with on connector axle, and two link plates are flexibly connected with two other axle on connector respectively.
Further, described arm-tie adopts high-strength insulating arm-tie as main traction and mounting rod, and arm-tie is horizontal structure, one end is conductor wire end, the other end is tower head end, and described conductor wire end is reliably connected with connector, and its tower head end is reliably connected with high-strength insulating pull rope.
Further, described link plate is for turning one's head link plate needle construction.
Further, the later top of described later link plate needle construction is 180 degree, and the interior slot space of formation is identical with the spatial altitude up and down between equilateral triangle, and later the inside groove height at top is 25mm, and water jacket height is 65mm.
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 two insulator string insulation tractor, described tractor comprises arm-tie 1, connector 2 and is connected to two link plates 3 on connector 2, connector 2 is the structure with intermediate gaps that upper and lower equilateral triangle connecting plate 7 is connected to form as axle by the bolt 8 at three angles, can arbitrarily adjustment direction and angle, one end of described arm-tie 1 is flexibly connected with the axle of on connector 2, and two link plates 3 are flexibly connected with two other axle on connector respectively.
Arm-tie 1 adopts high-strength insulating arm-tie (3 tonnes) as main traction and mounting rod, arm-tie 1 is in horizontal structure, one end is conductor wire end 5, the other end is tower head end 4, conductor wire end 5 is reliably connected with connector, and its tower head end 4 is reliably connected with high-strength insulating pull rope by the installing hole 6 on it.
Link plate 3 is later link plate needle construction, later link plate stressed a little in division design for legacy equipment after, two link plates automatically with triangle connection element close contact, increase pressure, makes the pulling force from insulation pulling plate all act on the triangle connection element of line hardware.
Later the later top of link plate needle construction be 180 degree, the space of formation and inside groove 9 identical with the spatial altitude up and down between equilateral triangle, to reduce the component acting on set square, turning one's head top inside groove 9 height is 25mm, and namely water jacket 10 turns one's head the height at top is 65mm.
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.
