Abstract
The invention discloses a core rod puller for a finished steel strand bundle. The core rod puller comprises the finished steel strand bundle, a restraint ring and a core rod. One end with a cone of the core rod is inserted to the center of one end of the finished steel strand bundle, and the other end of the core rod is protruded from the outer side of one end of the finished steel strand bundle. A pull ring is arranged at the other end of the core rod, and the end, with the cone, of the core rod inserted to the inside of the finished steel strand bundle is gradually reduced to the other end of the core rod to form a cylinder along the axis. The restraint ring is tightly sleeved on the outer edge of the finished steel strand bundle corresponding to the cylinder. The outline dimension of the restraint ring and the core rod is smaller than the inner diameter of a construction channel for pulling to thread the finished steel strand bundle in the subsequent process. The core rod puller has the advantages that since the finished steel strand bundle and the core rod are fastened integrally by the restraint ring, the finished steel strand bundle is driven to move by the core rod effectively; the core rod and the pull ring are integrated, so that strength is high, cost is low, convenience in change is achieved, twisting and deforming of the steel strand wires penetrating the construction channel can be avoided, and construction efficiency is high.

The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
Fig. 1 is structural representation of the present invention; Fig. 2 is A-A sectional view in Fig. 1; Fig. 3 is the full sectional view of Fig. 1.
The invention provides the plug tractor that a kind of finished product steel wire bundle is used, described plug tractor comprises: by a plurality of single steel strand 1a, make finished product steel wire bundle 1, confinement ring 2, the plug 3 that comb is weaved into bundle in order; Described plug 3 inserts the central inner of finished product steel wire bundle 1 one ends with conehead one end, the other end of plug 3 protrudes the outside that is arranged on finished product steel wire bundle 1 one ends, the other end of plug 3 is provided with traction draw ring 3a, and the diameter that plug 3 one ends insert finished product steel wire bundle 1 inner conehead diminishes along its axis to the other end gradually as cylinder; Described confinement ring 2 connect on finished product steel wire bundle 1 outer rim that is sleeved on plug 3 column parts and banding at finished product steel wire bundle 1 one ends; The outer profile size of described confinement ring 2 and plug 3 is less than follow-up traction finished product steel wire bundle 1 and wears the construction duct internal diameter sent.
Described plug 3 one end coneheads are the conical horn shape, and plug 3 is positioned at the outside of confinement ring 2 with conehead one end.
Hole dimension and pulling equipment or the supporting setting of tractive instrument in described traction draw ring 3a.
In particular, confinement ring 2 of the present invention is tubular annulus, and confinement ring 2 inwalls are pressed on finished product steel wire bundle 1, and the size of confinement ring 2 internal diameters is that the finished product steel wire bundle radical be equipped with is as required determined; The position that confinement ring 2 is sleeved on finished product steel wire bundle 1 is: confinement ring 2 connects finished product steel wire bundle 1 peripheral edge portion that is sleeved on plug 3 column parts, plug 3 is positioned at the outside of confinement ring 2 with conehead one end, by dedicated extruded equipment extruding confinement ring 2, leave over technique impression 2a after extruding on confinement ring 2 external diameters; After extruding, confinement ring 2 is integrated with finished product steel wire bundle 1 and plug 3, realizes when pulling plug 3 effect that finished product steel wire bundle 1 is servo-actuated.
Confinement ring 2 internal diameters are determined according to the steel strand radical that needs in reality to use, and can in 30～200mm scope, change; The external diameter of confinement ring 2 is less than the internal diameter of construction duct bellows.
As shown in Figure 1, Figure 3, the left end of described plug 3 inserts and is wrapped in finished product steel wire bundle 1 end, center, and the left end band conehead of plug 3 is the conical horn shape, and the right-hand member of plug 3 is the cylinder with traction draw ring 3a; The structure of plug 3 conical horn shapes is: the left end with conehead is that bottom face is large, the conical horn shape successively decreased to band traction draw ring 3a direction size along plug 3 axis.Plug 3 with the effect of conehead is: when the traction draw ring 3a of plug 3 right-hand members when pulled, utilize plug 3 cone inclineds to wear the finished product steel wire bundle 1 that moving restrained ring 2 bandings are integrated and move together, when plug 3 when pulled, the servo-actuated effect of finished product steel wire bundle 1.
Described plug and traction draw ring size can be made into standard size, and above-mentioned parts are convenient to processing and manufacturing and exchange.
Pulling equipment or tractive instrument are selected haulage cable (figure does not look) usually, haulage cable one end passes and is fixed tightly on traction draw ring 3a, again the haulage cable other end is connected with hoist engine, starting hoist engine is drawn, can drive the movement in bellows smoothly of whole finished product steel wire bundle 1,1 traction of finished product steel wire bundle is shifted out to bellows, then carry out next step tension steel strand operation.
The course of work of example of the present invention is as follows:
At first, the single steel strand 1a comb of regulation radical is compiled and arranged as finished product steel wire bundle 1, plug 3 band conehead one ends are inserted to finished product steel wire bundle 1 end, center, keep the outside that is exposed at finished product steel wire bundle 1 of plug 3 right-hand members, as shown in Figure 1;
Secondly, confinement ring 2 is inserted in to the peripheral edge portion of the column part insertion finished product steel wire bundle 1 of plug 3, extrusion equipment extruding confinement ring 2 with special-purpose, make confinement ring 2 bandings on finished product steel wire bundle 1, and plug 3 extruding of confinement ring 2, finished product steel wire bundle 1 and band traction draw ring 3a are integrated.As shown in Figure 1, Figure 3;
Above one embodiment of the present of invention are had been described in detail, described content is only preferred embodiment of the present invention, can not be considered to for limiting the scope that practices of the present invention.All equalizations of doing according to the present invention change or improve, and do not have substantial novelty to change, and all should belong in covering scope of the present invention.
