Patent CN103794348A, disclose a kind of transformer high-voltage bushing lead-in wire draw-gear, dress entirety is a columniform housing, T-shaped rotating shaft is provided with in housing, for avoiding lead-in wire knotting, the two ends of housing are respectively equipped with upper connector and lower connector, and upper connector is connected with pull rope.During use, whole device is put into bushing, lower connector, under gravity through the cavity of bushing, is then connected with lead-in wire, carries device and complete whole lead-in wire drawing-in motion finally by device.Although this device can be avoided, lead-in wire is twisted together, dog leg, but due to in-built restriction, its weight is relatively large with volume, tenesmus and on carry in process very easily occurring with inside pipe casing to rub or clash into sleeve pipe damaged with going between, the weight and volume with timer also limit the flexible use in the sleeve pipe of different size.
A kind of new casing of current urgent need installs thinking with raising to the emergency processing of accident and adaptibility to response, can apply in a flexible way among the bushing and lead-in wire of various different size, also can avoid lead-in wire and sleeve pipe to greatest extent in distraction procedure owing to rubbing and clashing into the damage occurred simultaneously.
Utility model content
The purpose of this utility model overcomes transformer high-voltage bushing lead-in wire to install the large problem of long difficulty consuming time, a kind of special transformer high-voltage bushing lead-in wire mounting bracket is provided, the utility model utilizes A-frame and assembly pulley to coordinate, the high-voltage connection of distinct interface can be drawn fast, both decreased and required number had been installed, turn improved bushing installation rate.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of transformer high-voltage bushing lead-in wire mounting bracket, comprises pull rope, also comprises: A-frame, assembly pulley and fast connector; Wherein A-frame is made up of pedestal, supporting leg and leg, and described pedestal is provided with through wires hole, and one end of three supporting legs is hinged mutually with base bottom respectively, and the other end is respectively equipped with leg; Assembly pulley is made up of the first pulley and the second pulley, and the first pulley and the second pulley to be arranged on successively on pedestal along through wires hole radial direction through pulley yoke and to make the tangent line of the first pulley and the axes coincide of through wires hole; Pull rope passes the through wires hole on pedestal through assembly pulley and is connected with fast connector.
Further, be connected on three summits of the equilateral triangle of base bottom surface in three described supporting legs are distributed in, respectively there is a lug junction of base bottom surface, supporting leg top through pin and lug hinged.
Further, described leg has positioning screw hole, in positioning screw hole, is provided with bolt.
The beneficial effects of the utility model are: 1, the open-angle of A-frame supporting leg is adjustable and with the design of positioning screw hole on bearing, this device all firmly can be connected with the cannula tip of various sizes, ensure that the stability of lead-in wire process.2, the setting of through wires hole relative position on the first pulley and pedestal, make to go between in distraction procedure and be in sleeve pipe centre position all the time, avoid when lead-in wire involves and sleeve pipe rubs, both can not damage the insulating barrier that lead-in wire is outside, the inwall of bushing can not be damaged again.3, adopt the assembly pulley of sister block, guide pull rope motion, structural safety, reliable, stability is high, not twisted wire, does not offset, and can effectively avoid, and the kink that goes between and dog leg occur in the process of traction.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, Figure 2, described in Fig. 3 and Fig. 4, transformer high-voltage bushing lead-in wire mounting bracket of the present utility model comprises: pedestal 1, supporting leg 2, bearing 3, positioning screw hole 4, first pulley 5, second pulley 6, wheel carrier 7, pull rope 8 and fast connector 9.As shown in Figure 4, pedestal is a plectane with through wires hole 1a, and the lower end of pedestal is hinged with three supporting legs 2, supporting leg end is provided with supporting seat 3, supporting seat has positioning screw hole 4, by pedestal 1, supporting leg 2 and supporting seat 3 jointly composition are used for the A-frame of firm whole device.Hinge between supporting leg 2 and pedestal 1 makes the subtended angle of support adjustable, like this can so that support be connected with the bushing end of various sizes, utilize positioning screw hole 4 set screw be preset on bearing to match, A-frame main part and cannula tip can be fixed, prevent support-moving.
Assembly pulley is made up of the first pulley 5 and the second pulley 6, and the first pulley 5 and the second pulley 6 to be arranged on successively on pedestal 1 along through wires hole 1a radial direction through pulley yoke and to make the tangent line of the first pulley and the axes coincide of through wires hole as shown in Figure 3, Figure 4.Pull rope 8 passes the through wires hole 1a on pedestal through assembly pulley and is connected with fast connector 9.When installation assembly pulley, guarantee the tangent line of the first pulley and the axes coincide of through wires hole, this design makes the centre position being in sleeve pipe around the pull rope on pulley all the time, avoid pull rope and lead-in wire in distraction procedure with the friction of bushing inner tubal wall, thus smoothly lead-in wire to be taken out of.
In technique scheme, the hinge of supporting leg and base bottom surface is achieved in the following ways: be connected on three summits of the equilateral triangle of base bottom surface in three supporting legs are distributed in, respectively there is a lug junction of base bottom surface, supporting leg top through pin and lug hinged.
In technique scheme, fast connector can also be designed to detachable, fast connector 9 is divided into pull rope joint and pigtail splice, removably connects between them.Pigtail splice is connected with lead-in wire to be drawn in bushing, and during use, pigtail splice can be arranged to different specifications, can change at any time when coordinating from different lead-in wires.
In such scheme, the periphery of fixed pulley is provided with the U-type groove 5a matched with pull rope, can play better guide effect to pull rope.
Using method of the present utility model is: according to the opening angle of the Sizes adjusting triangle support of bushing end, after adjustment, the positioning screw hole of this device on bearing is fixed on the end face of sleeve pipe, the axis of through wires hole and the dead in line of bushing on A-frame is guaranteed time fixing, and the outward flange of pulley will exceed sleeve upper end edge, improve stability when lead-in wire is drawn.During traction, one end of pull rope has manpower or pulling equipment to pull, the other end through assembly pulley through the cavity in bushing to it bottom, fast connector 9 is used to be connected with lead-in wire by pull rope, pulling traction rope, high pressure is drawn out to cannula tip by lead-in wire, thus completes the installment work of whole bushing.
