Abstract
The utility model discloses a finished steel strand bundle pushing device. The device comprises a hoop and a push head. One end of the hoop is connected to one end of the push head, and an inner hole of the other end of the hoop binds around one end of a finished steel strand bundle tightly after sleeving the finished steel strand bundle. The other end of the push head is a cone. The sizes of the outer contours of the hoop and the push head are smaller than the inner diameter of a construction tunnel, through which the finished steel strand bundle is pushed to pass later. The beneficial effects are that the hoop and the push head are fastened and connected into one body, so that processing and installation are convenient, and the construction efficiency is high; the front end of the push head is in the shape of a cone, and thus pushing is more smooth while a pushing device is used for pushing; and the device is simple in processing, convenient for replacement and low in cost. The hoop is already tightly fastened around the end of the finished steel strand bundle when leaving a factory, and thus the finished steel strand bundle can be pushed to pass through a corrugated pipe of the construction tunnel as soon as the corresponding push head is screwed onto the hoop in the field of construction.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is that the utility model is assemblied in structural representation on finished product steel wire bundle; Fig. 2 is partial sectional view in Fig. 1; Fig. 3 is the P portion enlarged drawing in Fig. 2.
As shown in the figure, the propulsion plant that the utility model provides a kind of finished product steel wire bundle to use, described propulsion plant comprises: banding ring 2, advance 3; Described banding ring 2 one end connect the one end that advances 3, after the inner hole sleeve of banding ring 2 other ends is dressed up product steel wire bundle 1 and banding on finished product steel wire bundle 1 one end; The other end of described propelling 3 is cone; Banding ring 2 is less than the pushed construction duct internal diameter of follow-up finished product steel wire bundle 1 with an outer profile size that advances 3.
Described banding ring 2 comprises with a syndeton that advances 3: banding ring 2 is threaded with advancing 3 use, and its screw connection structure comprises: the external screw thread cylinder of the banding ring internal thread 2b of banding ring 2 one end and propelling 3 one end screws.
In particular, the propulsion plant that a kind of propelling movement that the utility model provides is used through a kind of finished product steel wire bundle of construction duct bellows, this propulsion plant comprises banding ring 2 and advances 3; Described banding ring 2 is the female hollow rings of one end band, one end of banding ring 2 is threaded connection the one end that advances 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,, 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 after extruding, on banding ring 2 other end external diameters, leaves over technique impression 2a.
