Abstract
The invention provides a pay-off guide device for power. The pay-off guide device for power comprises a disc, wherein a hanging rod is fixed to the center of the disc, a hanging ring is arranged at the other end of the hanging rod, a plurality of disc pulley supports are arranged in the radial direction of the disc, an adjustment screw rod in threaded connection with each disc pulley support is arranged at the end of the corresponding disc pulley support, a nut is arranged on the corresponding adjustment screw rod, a pulley support in threaded connection with each adjustment screw rod is arranged at the outer end of the corresponding adjustment screw rod, a pulley is arranged on each pulley support, and a smooth layer is laid on a wheel groove surface of each pulley. During pay-off construction, the pay-off guide device for power can reduce the tortuosity of a carbon fiber composite core aluminum conductor conveniently in time to ensure the carbon fiber composite core aluminum conductor to be prevented from damage.
Description
Technical field
The present invention relates to power transmission line spanning equipment, be specifically related to a kind of electric power pay-off guide device.
Background technology
Along with the fast development of power grid construction, the application of aluminium twisted wire with carbon fiber composite core is more and more extensive.At present, in the erection construction of aluminium twisted wire with carbon fiber composite core, need to use the fulcrum of high tower pulley block as aluminium twisted wire with carbon fiber composite core slip advance.But the high tower pulley block being applied to aluminium twisted wire with carbon fiber composite core at present remains the high tower pulley block continuing to use original steel core wire, and structure is without any change.In order in the process used can dynamic monitoring to the temperature of aluminium twisted wire with carbon fiber composite core line body, contains a carbon-point in aluminium twisted wire with carbon fiber composite core, is provided with an optical fiber in carbon-point, because the toughness of carbon-point and optical fiber is very poor, larger flexibility can not be had.Traditional high tower pulley block is used to show, in unwrapping wire process, aluminium twisted wire with carbon fiber composite core is in the inlet side of high tower pulley block with go out end and bend because the problem of angle is the most easily formed, very easily there is Carbon Fiber Damage or fracture, and carbon-point and optical fiber fracture, do not reach construction requirement, affect construction schedule.
Summary of the invention
Technical problem to be solved by this invention how to enable aluminium twisted wire with carbon fiber composite core dynamically be changed by the angle of high tower pulley block when unwrapping wire, thus avoid the damage of aluminium twisted wire with carbon fiber composite core.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of electric power pay-off guide device, comprises disk, sets firmly peg in the center of described disk, and the other end of peg establishes link; Described disk radially arranges multiple disk pulley bracket, the adjusting screw(rod) be threaded with it is established in each disk pulley bracket end, adjusting screw(rod) establishes nut, the pulley bracket be threaded with it is established respectively in each adjusting screw(rod) outer end, each pulley bracket establishes pulley, the groove face of each pulley lays smooth layer.
Described smooth layer is chromium coating, graphite linings or ceramic layer.
The present invention adopts the electric power pay-off guide device designed by technique scheme, owing to being provided with multiple disk pulley bracket on disk, each disk pulley bracket is connected with the pulley bracket being provided with pulley by corresponding adjusting screw(rod), the distance between disk pulley bracket and pulley bracket is regulated by the nut rotated on adjusting screw(rod), thus the distance changed between pulley and disk, correspondingly have adjusted aluminium twisted wire with carbon fiber composite core in inlet side of the present invention and the angle going out end, also namely have adjusted to adjustability the flexibility of aluminium twisted wire with carbon fiber composite core.Like this, just can facilitate, reduce in time the flexibility of aluminium twisted wire with carbon fiber composite core by the present invention, guarantee that it is injury-free.
Accompanying drawing explanation
Fig. 1 represents the structural representation of electric power pay-off guide device of the present invention;
Fig. 2 represents the structural representation of governor motion in Fig. 1.
Embodiment
Illustrate below in conjunction with the structure of accompanying drawing to electric power pay-off guide device of the present invention.
See Fig. 1 and Fig. 2, electric power pay-off guide device of the present invention, comprises disk 1, sets firmly peg 6 in the center of disk 1, and the other end of peg 6 establishes link 7, and link 7 is for hanging over transmission tower by disk 1.On disk 1, radially direction arranges multiple disk pulley bracket 5, the end of each disk pulley bracket 5 is established the adjusting screw(rod) 8 be threaded connection with it, adjusting screw(rod) 8 is established nut 9.The pulley bracket 3 be threaded connection with it is established respectively in the outer end of each adjusting screw(rod) 9, each pulley bracket 3 establishes pulley 2, the groove face of each pulley 2 lays smooth layer, smooth layer can reduce the coefficient of friction between aluminium twisted wire with carbon fiber composite core and pulley 2, thus alleviates the tractive effort of fiber composite core aluminum stranded wire.Smooth layer can be chromium coating, graphite linings or ceramic layer.Adjusting screw(rod) 8, nut 9 form the governor motion 4 of height of pulley of the present invention, thus when unwrapping wire the flexibility of dynamic less aluminium twisted wire with carbon fiber composite core as the case may be, guarantee that aluminium twisted wire with carbon fiber composite core is injury-free.
The present invention is on probation through trial-production, solve aluminium twisted wire with carbon fiber composite core preferably and there is the large defect of flexibility by existing traditional high tower pulley block, injury-free when ensure that aluminium twisted wire with carbon fiber composite core unwrapping wire, ensure carrying out smoothly of electric power payingoff construction.
Claims (2)
1. an electric power pay-off guide device, comprises disk, it is characterized in that: set firmly peg in the center of described disk, and the other end of peg establishes link; Described disk radially arranges multiple disk pulley bracket, the adjusting screw(rod) be threaded with it is established in each disk pulley bracket end, adjusting screw(rod) establishes nut, the pulley bracket be threaded with it is established respectively in each adjusting screw(rod) outer end, each pulley bracket establishes pulley, the groove face of each pulley lays smooth layer.
2. electric power pay-off guide device according to claim 1, is characterized in that described smooth layer is chromium coating, graphite linings or ceramic layer.
