Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described in further detail.
Fig. 1 is the structural representation of the present invention；Fig. 2 is A-A sectional view in Fig. 1；Fig. 3 is Fig. 1
Full sectional view.
The present invention provides the core rod puller of a kind of finished steel strand bundle, and described core rod puller includes:
Made in order comb by multiple single steel strand 1a and compile bundles of finished steel strand bundle 1, confinement ring 2, plug 3；
The central interior of finished steel strand bundle 1 one end, another of plug 3 are inserted in described plug 3 band conehead one end
End protrudes the outside being arranged on finished steel strand bundle 1 one end, and the other end of plug 3 is provided with traction draw ring
3a, the diameter of the internal conehead of finished steel strand bundle 1 is inserted along its axis to the other end gradually in plug 3 one end
Diminish as cylinder；Outside the through finished steel strand bundle 1 being sleeved on plug 3 column part of described confinement ring 2
On edge and banding is in finished steel strand bundle 1 one end；The outer profile size of described confinement ring 2 and plug 3 is little
The construction duct internal diameter sent is worn in follow-up traction finished product steel wire bundle 1.
Described plug 3 one end conehead is conical horn shape, and plug 3 band conehead one end is positioned at confinement ring 2
Outside.
Described traction draw ring 3a hole size and pulling equipment or the supporting setting of tractive instrument.
In particular, the confinement ring 2 of the present invention is tubular annulus, and confinement ring 2 inwall is pressed on finished product
On steel wire bundle 1, the size of confinement ring 2 internal diameter, is the finished steel strand bundle radical being equipped with as required
Determine；The position that confinement ring 2 is sleeved in finished steel strand bundle 1 is: confinement ring 2 is through to be sleeved on
Finished steel strand bundle 1 peripheral edge portion of plug 3 column part, plug 3 band conehead one end is positioned at confinement ring
The outside of 2, extrudes confinement ring 2 with dedicated extruded equipment, leaves over technique after extruding on confinement ring 2 external diameter
Impression 2a；After extruding, confinement ring 2 is integrated with finished steel strand bundle 1 and plug 3, it is achieved when pulling core
During rod 3, the effect that finished steel strand bundle 1 is servo-actuated.
Confinement ring 2 internal diameter, can be 30～200mm according to needing the steel strand wires radical used to determine in reality
In the range of change；The external diameter of confinement ring 2 is less than the internal diameter of construction duct corrugated tube.
As shown in Figure 1, Figure 3, the left end of described plug 3 inserts and is wrapped in finished steel strand bundle 1
Central end, the left end band conehead of plug 3 is conical horn shape, and the right-hand member of plug 3 is for draw with traction
The cylinder of ring 3a；The structure of plug 3 conical horn shape is: the left end of band conehead is that bottom face is big, along core
Rod 3 axis are to the conical horn shape of band traction draw ring 3a direction decreasing dimensions.The effect of plug 3 band conehead
Be: when plug 3 right-hand member traction draw ring 3a when pulled, utilize plug 3 cone inclined to wear dynamic restrained
The finished steel strand bundle 1 that ring 2 banding is integrated moves together, i.e. when plug 3 when pulled, finished steel
The servo-actuated effect of strand bundle 1.
Described plug and traction draw ring size can be made into standard size, and above-mentioned parts are easy to processing and manufacturing with mutual
Change.
Pulling equipment or tractive instrument generally select haulage cable (figure does not regards), haulage cable one end
Pass and be fixed tightly on traction draw ring 3a, then the haulage cable other end is connected with hoist engine, start volume
The machine of raising draws, and can drive the movement in corrugated tube smoothly of whole finished steel strand bundle 1, will
Finished steel strand bundle 1 traction removal corrugated tube, then carry out next step tension steel strand operation.
The work process of present example is as follows:
First, the single steel strand 1a comb of regulation radical is compiled arrangement is finished steel strand bundle 1, by plug
Finished steel strand bundle 1 central end is inserted in 3 band conehead one end, and keep plug 3 right-hand member is exposed at finished steel
The outside of strand bundle 1, as shown in Figure 1；
Secondly, the column part that confinement ring 2 is inserted in plug 3 inserts the outer edge of finished steel strand bundle 1
Point, extrude confinement ring 2 with special extrusion equipment, make confinement ring 2 banding in finished steel strand bundle 1,
Plug 3 extruding of confinement ring 2, finished steel strand bundle 1 and band traction draw ring 3a is integrated.As Fig. 1,
Shown in Fig. 3；
Being described in detail one embodiment of the present of invention above, described content is only the present invention's
Preferred embodiment, it is impossible to be considered to practice scope for limit the present invention.All according to institute of the present invention
The impartial change done or improvement, do not have substantial novelty to change, all should belong to containing of the present invention
In the range of.
