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 partial sectional view among Fig. 1; Fig. 3 is the P section enlarged drawing among Fig. 2.
As shown in the figure, the invention provides the propulsion plant that a kind of finished product steel wire bundle is used, described propulsion plant comprises: banding ring 2, advance 3; Described banding ring 2 one ends connect advance an end of 3, the inner hole sleeve of banding ring 2 other ends dress up behind the product steel wire bundle 1 and banding on finished product steel wire bundle 1 one ends; The other end of described propelling 3 is cone; Banding ring 2 with advance an outer profile size of 3 less than the pushed construction duct internal diameter of follow-up finished product steel wire bundle 1.
Described banding ring 2 comprises with a syndeton that advances 3: banding ring 2 is threaded with advancing 3 usefulness, and its screw connection structure comprises: the external screw thread cylinder of the banding ring internal thread 2b of banding ring 2 one ends and propelling 3 one end screws.
In particular, the propulsion plant that a kind of finished product steel wire bundle of construction duct bellows is used is passed in a kind of propelling movement provided by the invention, and this propulsion plant comprises banding ring 2 and advances 3; Described banding ring 2 is that an end is with the hollow ring of internal thread, one end of banding ring 2 is threaded connection and advances an end of 3, the other end of banding ring 2, with dedicated extruded equipment extruding banding ring 2 other ends are squeezed on finished product steel wire bundle 1 one ends, namely, the inwall of banding ring 2 other ends is pressed on finished product steel wire bundle 1 one ends and with finished product steel wire bundle 1 and is integrated, and leaves over technique impression 2a at banding ring 2 other end external diameters after the extruding.
The size of the internal diameter of described banding ring 2 determines that according to the radical of single steel strand 1a in the equipped finished product steel wire bundle 1 internal diameter of banding ring 2 generally changes in 30～200mm scope; Banding ring 2 and advance an outer profile size of 3 less than inside diameter of bel is convenient to the smoothly pushed bellows duct of passing of follow-up finished product steel wire bundle 1.
