Abstract
The invention discloses a tractor for a finished steel strand. The tractor comprises a hoop and a tractor body. One end of the hoop is connected with one end of the tractor body, and one end of the finished steel strand is sleeved with the hoop after the finished steel strand is sleeved with an inner hole of the other end of the hoop. The other end of the tractor is provided with a pull ring connected with traction equipment. The size of the periphery of the hoop and the size of the periphery of the tractor body are smaller than the inner diameter of a construction hole channel which the finished steel strand is pulled to penetrate. The tractor has the advantages that the hoop and the tractor body with the pull ring are tightly connected as a whole, and the tractor is convenient to machine and install and high in construction efficiency; the end portion of the finished steel strand is sleeved with the hoop when the hoop is delivered, so that as long as the corresponding tractor is assembled on the hoop in a screwing mode on a construction site, the finished steel strand starts to be threaded; special squeezing equipment and tools which are used for fixing the hoop on the end portion of the finished steel strand are simple in structure and low in manufacturing cost, and the hoop and the finished steel strand can be firmly combined as a whole.

In to building, road and bridge building operations, need many prestressing tendons are made in order, penetrate in the prestressed pore passage that has prepared, namely in the corrugated conduit.Finished product steel wire bundle (claiming again " comb is compiled bundle ") is worn in corrugated conduit when sending, and need to a special tractor be set at finished product steel wire bundle front end.The quality of retractor structures design and the convenience that should use have a significant impact the quality of constructing.
Chinese utility model patent 201120371131.2 has been announced the threading-in device that a kind of steel strand comb is compiled bundle usefulness, this threading-in device comprises lead seat and connects head, the 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, connects an inwall of rear end hollow cylinder and is connected with the lead seat outer wall thread, and connecting an other end has suspension ring.
There is following deficiency in above-mentioned existing technology Patent: 1, a special head that connects is arranged between lead seat and suspension ring, connect head and be front end circular cone, rear end hollow cylinder, and internal thread is arranged in the corresponding construction, processing is inconvenient.2, at the construction field (site), need will connect first head and connect lead seat, will connect suspension ring again and connect the hollow cylinder that connects a rear end, construction sequence is comparatively loaded down with trivial details.3, connect head and connect suspension ring and need to make different specifications according to the radical of steel strand, will prepare so at the construction field (site) one of different size and wear leader and connect suspension ring, use inconvenience.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of banding ring simple in structure is provided, this banding ring can firmly be locked finished product steel wire bundle end fast, and can conveniently connect the tractor that a kind of finished product steel wire bundle of draw-gear is used.
The technical scheme that solves the problems of the technologies described above is: the tractor that a kind of finished product steel wire bundle is used, and described tractor comprises: banding ring, tractor; One end of described banding ring one end connection tractor, the inner hole sleeve of the banding ring other end dress up behind the product steel wire bundle and banding on finished product steel wire bundle one end; The other end of described tractor is provided with the draw ring that connects pulling equipment; The outer profile size of banding ring and tractor is worn the construction duct internal diameter that send less than follow-up traction finished product steel wire bundle.
Preferred version is: described banding ring comprises with the syndeton of tractor: banding ring and tractor are with being threaded, and its screw connection structure comprises: the external screw thread cylinder of the internal thread hole of banding ring one end and tractor one end screws.
Preferred version is: hole dimension and the supporting setting of pulling equipment tractive instrument in the draw ring of the described tractor other end.
The invention has the beneficial effects as follows: the present invention overcomes the shortcoming of prior art, and advantage of the present invention is as follows:
1) banding ring of the present invention is integrated with being fastenedly connected with the tractor of draw ring, has processing, characteristics easy for installation, and efficiency of construction is high.
2) the banding ring has just bound round when dispatching from the factory and has been fastened on finished product steel wire bundle end, therefore at the construction field (site) as long as corresponding tractor screwed be fitted on the banding ring, just can begin to wear and send the finished product steel wire bundle.
3) the banding ring is fixed on dedicated extruded equipment and the tool construction of finished product steel wire bundle end simple, cost is low, and banding is effective, and banding ring and finished product steel wire bundle can firmly be integrated.

The specific embodiment
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 on the finished product steel wire bundle; Fig. 2 is A-A sectional view among Fig. 1; Fig. 3 is partial sectional view among Fig. 1; Fig. 4 is the P section enlarged drawing among Fig. 3.
As shown in the figure, the invention provides the tractor that a kind of finished product steel wire bundle is used, described tractor comprises: banding ring 2, tractor 3; One end of described banding ring 2 one end connection tractors 3, the inner hole sleeve of banding ring 2 other ends dress up behind the product steel wire bundle and banding on an end of finished product steel wire bundle 1.
The other end of described tractor 3 is provided with the draw ring 3b that connects pulling equipment (figure does not look); The outer profile size of banding ring 2 and tractor 3 is worn the internal diameter of the construction duct bellows that send less than follow-up traction finished product steel wire bundle 1.
Described banding ring 2 comprises with the syndeton of tractor 3: banding ring 2 is threaded with tractor 3 usefulness, and screw connection structure comprises between described banding ring 2 and the tractor 3: the external screw thread cylinder of the internal thread hole of banding ring 2 one ends and tractor 3 one ends screws.
The supporting setting of hole dimension and pulling equipment or tractive instrument in the draw ring 3b of described tractor 3 other ends (figure does not look).
In particular, the tractor that a kind of finished product steel wire bundle provided by the invention is used comprises banding ring 2 and tractor 3; The other end of described banding ring 2 with dedicated extruded equipment extruding, is squeezed in banding ring 2 other ends on the finished product steel wire bundle 1, namely, the inwall of banding ring 2 other ends is pressed on the finished product steel wire bundle 1, after the extruding, leaves over technique impression 2a at banding ring 2 other end external diameters.
