Abstract
The utility model relates to a casing leading-out wire special tool in 66kV and higher transformer casing installation working in the power system substation maintenance profession. The casing leading-out wire special tool comprises a traction bolt, a bolt head rotating frame and a threading hole. The outer surface of the traction bolt is provided with an external screw thread. The bolt head rotating frame is screwed on the traction bolt and can rotate freely. Two ends of the traction bolt are respectively provided with a leading-out wire fixing structure and a traction wire fixing structure. According to the casing leading-out wire special tool, through the bolt head rotating frame capable of rotating freely, the tool can freely rotate along a wire strength direction of the leading-out wire and release wire strength generated by distortion in pulling a transformer coil leading-out wire, thus the transformer coil leading-out wire passes through the casing smoothly, the hooking and catching phenomena of the leading-out wire are avoided, the working difficulty is reduced, and the working efficiency is raised. In addition, since the casing leading-out wire special tool is compact and lightweight, the tool is easy to carry and use, material taking is convenient, and the cost is low.
Description
Technical field
The utility model relates to a kind of lead-in wire aid, and particularly the sleeve pipe lead-out wire specific purpose tool of a kind of electric power system substation equipment maintenance and repair specialty when 66 kilovolts and above bushing shell for transformer installation exercise, belong to the substation equipment maintenance and repair technical field.
Background technology
Bushing shell for transformer the transformer coil lead-out wire need to be passed sleeve pipe, and the transformer coil lead-out wire is soft, and sleeve pipe is long and narrow when mounted, and sleeve opening is smaller, and it is a job of relatively wasting time and energy that lead-out wire is passed sleeve pipe.Be screwed in sleeve pipe lead-out wire top with a bolt in the past, pulled with the 8# galvanized iron wire, and the sleeve pipe lead-in wire often can occur and beat hook, catching phenomenon.Cause lead-out wire to pass the sleeve pipe work difficulty large, reduced the efficient of transformer overhaul.
Summary of the invention
The utility model provides a kind of sleeve pipe lead-out wire specific purpose tool for above-mentioned problems of the prior art, has solved the specialty such as electric power system substation equipment maintenance and repair when a sleeve pipe installation exercise, and the transformer coil lead-out wire passes the problem of sleeve pipe inconvenience.
The technical solution of the utility model is as follows:
Comprise towing pin, bolt head swivel mount and through wires hole, the outer surface of towing pin is provided with external screw thread, and bolt head swivel mount spinning also can freely be rotated on towing pin, and the two ends of towing pin arrange respectively leading-out wire fixing structure and draught line fixed structure.
Described outgoing line connection structure is, towing pin is provided with nut, and the internal thread of nut and towing pin and lead-out wire external screw thread are supporting.
Described outgoing line connection structure is, the termination of towing pin is provided with internal thread hole, and the external screw thread of internal thread hole and lead-out wire is supporting.
Described towing pin is provided with through wires hole.
Described towing pin one end arranges firm, and through wires hole is arranged on securing member.
Be connected with pull rope on described through wires hole.
The utlity model has following advantage:
The work that when using this sleeve pipe lead-out wire specific purpose tool can simplify the sleeve pipe installation, the transformer coil lead-out wire passes sleeve pipe.By can be freely movable bolt head swivel mount, can be along with the line strength direction automatic rotation of lead-out wire, discharge the line strength that distortion produces when pulling the transformer coil lead-out wire, make the transformer coil lead-out wire pass smoothly sleeve pipe, avoid occurring lead-out wire and beat hook, catching phenomenon, reduce work difficulty, raising work effect.In addition, easy to carry and use due to this sleeve pipe lead-out wire specific purpose tool small volume and less weight, to draw materials conveniently, cost is low.

Fig. 2 is example structure schematic diagram of the present utility model.
In figure, 1, towing pin, 2, bolt head swivel mount, 3, through wires hole, 4, nut, 5, securing member, 6, internal thread hole.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe the utility model in detail.
Embodiment 1
As shown in Figure 1, select the lead screw of diameter 8mm or 10mm to make towing pin 1, the outer surface of towing pin 1 is provided with external screw thread, bolt head swivel mount 2 spinnings also can freely be rotated on towing pin 1, the internal thread of bolt head swivel mount 2 and the external screw thread of towing pin 1 are supporting, towing pin 1 is respectively equipped with securing member 5 and nut 4 in the both sides of bolt head swivel mount 2, is provided with through wires hole 3 perpendicular to the towing pin center line on securing member 5, is connected with pull rope on through wires hole 3; It is supporting that the internal thread of nut and towing pin 1 and coil are drawn the external screw thread of money.
As shown in Figure 2, select the lead screw of diameter 8mm or 10mm to make towing pin 1, the outer surface of towing pin 1 is provided with external screw thread, bolt head swivel mount 2 spinnings also can freely be rotated on towing pin 1, the internal thread of bolt head swivel mount 2 and the external screw thread of towing pin 1 are supporting, one end of towing pin 1 is provided with securing member 5, is parallel to the towing pin center line on securing member 5 and is provided with through wires hole 3, is connected with pull rope on through wires hole 3; The other end of towing pin 1 is provided with internal thread hole 6, and the external screw thread of internal thread hole and lead-out wire is supporting.
Operation principle of the present utility model and process are as follows:
Bolt head swivel mount 2 is mobilizable with the junction of towing pin 1, and after the lead-out wire of towing pin 1 and transformer coil was connected and fixed, bolt head swivel mount 2 can freely rotate release wire strength.Through wires hole 3 is convenient to pass the soft materials such as cloth, as pulling out the transformer coil lead-out wire outward toward sleeve pipe.During use, an end size threaded according to the transformer coil lead-out wire selected the sleeve pipe lead-out wire specific purpose tool of suitable size, a cloth or long rope passed through wires hole, and fasten.Then, to grow rope one end and stay the cover tube outside, sleeve pipe lead-out wire specific purpose tool will be passed in sleeve opening, and with the threaded engagement on transformer coil lead-out wire top, be connected firmly, pulling system has an end of long rope just can like a cork the transformer coil lead-out wire be passed sleeve pipe.
Protection range of the present utility model is as the criterion with claim, not limited by specific embodiment.
