Description
Technical field
What the present invention relates to is the tractor of finished steel strand bundle, particularly be a kind of tractor of finished steel strand bundle.
Background technology
To in building, road and bridge building operations, need many prestressing tendons to make in order, penetrate in the prestressed pore passage prepared, namely in corrugated conduit.When finished steel strand bundle (also known as " comb compile bundle ") is worn and sent in corrugated conduit, need to arrange in finished steel strand bundle front end a special tractor.The quality that retractor structures designs and the convenience that should use, have a significant impact the quality of construction.
Chinese utility model patent 201120371131.2 discloses the threading-in device that a kind of steel strand comb compiles bundle, this threading-in device comprises lead seat and connects head, lead seat outer wall is threaded, connect head and contain front end circular cone and rear end hollow cylinder, the axle center of circular cone is provided with through hole, the inwall of hollow cylinder is provided with internal thread, and connect an inwall for rear end hollow cylinder and be connected with lead seat outer wall thread, connecting an other end has suspension ring.
Above-mentioned existing technology Patent exists following not enough: between lead seat and suspension ring, 1, have one special to connect head, connecting head is front end circular cone, rear end hollow cylinder, and has internal thread in corresponding construction, and processing is inconvenient.2, at the construction field (site), need first to connect head and connect lead seat, then connect connecting suspension ring the hollow cylinder connecting a rear end, construction sequence is comparatively loaded down with trivial details.3, connecting head and connecting suspension ring needs to make different specifications according to the radical of steel strand, will prepare a set of of different size so at the construction field (site) and connects head and connect suspension ring, and use inconvenience.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure simple hoop, this hoop can firmly lock finished steel strand bundle end fast, and conveniently can connect the tractor of a kind of finished steel strand bundle of draw-gear.
The technical scheme solved the problems of the technologies described above is: a kind of tractor of finished steel strand bundle, and described tractor comprises: hoop, tractor; One end of described hoop one end connection tractor, extrude with dedicated extruded equipment after the inner hole sleeve of the hoop other end dresses up product steel wire bundle, the hoop other end is squeezed on finished steel strand bundle one end, after extruding, on hoop other end external diameter, leaves over technique impression; The other end of described tractor is provided with the draw ring connecting pulling equipment; The outer profile size of hoop and tractor is less than follow-up traction finished product steel wire bundle and wears the construction duct internal diameter sent;
Described hoop comprises with the syndeton of tractor: hoop and tractor are with being threaded, and its screw connection structure comprises: the internal thread hole of hoop one end and the external screw thread cylinder of tractor one end screw.
Preferred version is: the draw ring hole size of the described tractor other end and the supporting setting of pulling equipment tractive instrument.
The invention has the beneficial effects as follows: the present invention overcomes the shortcoming of prior art, advantage of the present invention is as follows:
1) hoop of the present invention is fastenedly connected with the tractor of band draw ring and is integrated, and have processing, feature easy for installation, efficiency of construction is high.
2) hoop has just been bound round when dispatching from the factory and has been fastened on finished steel strand bundle end, is fitted in hoop, just can starts to wear and send finished steel strand bundle as long as therefore screwed by corresponding tractor at the construction field (site).
3) the dedicated extruded equipment and the tool construction that hoop are fixed on finished steel strand bundle end are simple, and cost is low, and gripping effect is good, and hoop and finished steel strand bundle can firmly be integrated.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
Fig. 1 is that the present invention is assemblied in structural representation in finished steel strand bundle; Fig. 2 is A-A sectional view in Fig. 1; Fig. 3 is partial sectional view in Fig. 1; Fig. 4 is the P portion enlarged drawing in Fig. 3.
As shown in the figure, the invention provides a kind of tractor of finished steel strand bundle, described tractor comprises: hoop 2, tractor 3; One end of described hoop 2 one end connection tractor 3, after the inner hole sleeve of hoop 2 other end dresses up product steel wire bundle and banding on one end of finished steel strand bundle 1.
The other end of described tractor 3 is provided with the draw ring 3b connecting pulling equipment (figure does not look); Hoop 2 is less than with the outer profile size of tractor 3 internal diameter that follow-up traction finished product steel wire bundle 1 wears the construction duct bellows sent.
Described hoop 2 comprises with the syndeton of tractor 3: hoop 2 and tractor 3 are with being threaded, and between described hoop 2 and tractor 3, screw connection structure comprises: the internal thread hole of hoop 2 one end and the external screw thread cylinder of tractor 3 one end screw.
The draw ring 3b hole size of described tractor 3 other end and pulling equipment or tractive instrument (scheming not look) supporting setting.
In particular, the tractor of a kind of finished steel strand bundle provided by the invention, comprises hoop 2 and tractor 3; The other end of described hoop 2, extrudes with dedicated extruded equipment, is squeezed in finished steel strand bundle 1 by hoop 2 other end, namely, the inwall of hoop 2 other end is pressed in finished steel strand bundle 1, after extruding, hoop 2 other end external diameter leaves over technique impression 2a.
One end of hoop 2 is hollow cylinder, and hoop 2 one end internal diameter is provided with hoop internal thread 2b.
Described tractor 3 one end is cylindrical external thread 3a, and cylindrical external thread 3a is connected with the hoop internal thread 2b in hoop 2, and the other end of tractor 3 is provided with draw ring 3b.
The size of the internal diameter of described hoop 2, determine according to the radical of single steel strand 1a in equipped finished steel strand bundle 1, the internal diameter of hoop 2 generally changes within the scope of 30 ~ 200mm; The outer profile size of hoop 2 and tractor 3 is less than inside diameter of bel, is convenient to follow-up traction finished product steel wire bundle 1 and can wears smoothly and send bellows duct.
The course of work of the present invention is as follows: be inserted in the end of finished steel strand bundle 1 in hoop 2 other end endoporus, extrude at hoop 2 other end with special extrusion equipment, make hoop 2 other end and finished steel strand bundle 1 extrude banding to be integrated, namely finished product steel wire bundle 1 be close to hoop 2 inwall on and reinforce; One end cylindrical external thread 3a of the hoop internal thread 2b of hoop 2 one end and tractor 3 is screwed and connects as one, make finished steel strand bundle 1, hoop 2 and tractor 3 form integrative-structure like this;
Haulage cable (figure does not look) selected usually by pulling equipment or tractive instrument, haulage cable one end is passed and is fixed tightly on the draw ring 3b of tractor 3, again the haulage cable other end is connected with hoist engine, start hoist engine to draw, the movement of whole finished steel strand bundle 1 smoothly in bellows can be driven, bellows is shifted out in finished steel strand bundle 1 traction, then carries out next step tension steel strand operation.
Be described in detail one embodiment of the present of invention above, described content is only preferred embodiment of the present invention, can not be considered to of the present inventionly practice scope for limiting.All equalizations done according to the present invention change or improve, and do not have substantial novelty to change, all should belong in covering scope of the present invention.
