The upper ends of the landing legs are connected with the outer circles of the crossbeams into a whole; a guide pulley with an inner side tangent line in line with the center line of the upper round bracket is arranged on the lower end surface of the center part of the upper round bracket, and fastening bands for fastening the landing legs are arranged on the landing legs. The device provided by the utility model can straightly lead out the high-voltage winding casing tap in a more convenient and more labor-saving way. The device avoids the entanglement among ropes, lifting ropes and chain blocks, reduces the labor consumption for tap lead-out, and improves the work efficiency. The device realizes the optimization and combination of various types of operating tools, and indeed solves the difficulty in leading out the transformer high-voltage winding tap.
Description
Technical field
The utility model relates to the tap of a kind of transformer high-voltage winding sleeve pipe and draws guider.
Background technology
Along with constant development of economy, the continuing to increase of power grid construction dynamics, more transformer participates in power grid construction, and in addition As time goes on, the overhaul of transformer is also more and more frequent, and the sleeve pipe maintenance of transformer also gets more and more.But at present electric power enterprise is when the tap of transformer high-voltage winding sleeve pipe is drawn, and what generally adopt is: the crane casing flange that plays, utilize chain block to adjust the setting angle of sleeve pipe, and hang pulley and draw transformer tapping with rope on suspension hook.There is following defective like this: the one, draw in tap and to have following problem in the application, bushing is heavier, and generally all an angle of inclination is arranged with the transformer body, the interior copper pipe axle center that rope guiding point and sleeve pipe are drawn in tap is not a straight line, and rope copper pipe upper port in sleeve pipe is drawn and is subjected to very big frictional force; The 2nd, rope point-blank also is not difficult to rotate in sleeve pipe internal cause guiding point and transformer high-voltage tap, makes the transformer high-voltage tap produce dog leg at voltage equalizing ball place, sleeve pipe bottom when drawing, and makes tap be difficult to pull out or rope is broken.The 3rd,, draw rope and lifting rope and chain block and also be easy to generate winding, reduce operating efficiency.
The utility model content
The purpose of this utility model provides a kind of high pressure winding sleeve pipe tap straight line can being drawn, save manpower and time, effectively avoided in the work progress construction appliance that guider is drawn in the transformer high-voltage winding sleeve pipe tap of the influence of workmen, device security and construction schedule.
For achieving the above object, the technical solution adopted in the utility model is: guider is drawn in the tap of a kind of transformer high-voltage winding sleeve pipe, form by the circumferential equally distributed a plurality of rack legs of electric fan shape upper circular support and bottom, the upper circular support is made up of a plurality of radially equally distributed crossbeams, crossbeam is connected as a single entity in the centre, and the upper end of rack leg and the cylindrical of crossbeam are connected as a single entity; The lower surface at upper circular carriage center position is provided with leading block, and the inboard tangent line of leading block and upper circular carriage center line are point-blank; Rack leg is provided with the restraint zone that is used for the securing bracket leg.
Guider is drawn in the tap of above-mentioned transformer high-voltage winding sleeve pipe, and the quantity of described rack leg is at least 2.Be generally individual 4 or 3 and get final product, rack leg is many more, and is fastening firm more.Drawing the rope handled easily with pulley is as the criterion.
The beneficial effects of the utility model are: adopt circumferentially equally distributed a plurality of rack legs of upper circular support and bottom, the lower surface at carriage center position, top is provided with inboard tangent line and upper circular carriage center line leading block point-blank, being used for the tap of transformer high-voltage sleeve pipe draws, can realize utilizing rope in sleeve pipe transformer high-voltage tapping straight line to be drawn, it is convenient, laborsaving that tap is drawn; Simultaneously, avoid the winding of rope and lifting rope and chain block, reduce workmen's use amount that tap is drawn, increase work efficiency.Also reduce tap wearing and tearing to internal surface of sleeve pipe in spill process, significantly reduced the damage of maintenance other parts of transformer.
Adopt rack leg to be provided with the restraint zone that is used for the securing bracket leg, can make being connected of rack leg and sleeve pipe, convenient fixing quick.
The utility model is used for the tap of transformer high-voltage sleeve pipe and draws.Have in light weight, good looking appearance, simple in structure, easy to operate; The field is with low cost, economy easy to use, stable performance; Need not special maintaining; Be not subjected to natural environment, construction site, the characteristics such as restriction that personnel cooperate.Realized the optimum organization of several work instrument, really solved the transformer high-voltage tapping and drawn difficult operation difficult problem.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
