The conical adjusting ring 5 is provided with strip-shaped through grooves 7 along the extending direction of the conical adjusting ring, the number of the through grooves 7 is four, the four through grooves 7 are distributed in an equidistant annular mode, the length of the through grooves 7 is not more than half of the length of the conical adjusting ring 5, and the second limiting ring 10 is divided into four sections by the through grooves 7. The outer surface of the conical adjusting ring 5 is in threaded connection with an adjusting nut 8.
Specifically, the minimum diameter of the inner part of the conical adjusting ring 5 is matched with the outer surface of the prestressed steel strand 1. The diameters of the first stop collar 9 and the second stop collar 10 are both larger than the inner diameter of the adjusting nut 8. The through groove 7 is used to change the diameter of one end of the conical adjusting ring 5 according to the adjustment of the adjusting nut 8, thereby achieving the effect of fixing the prestressed steel strand 1.
Through above-mentioned technical scheme, the regulation through adjusting nut 8 makes the diameter of toper adjustable ring 5 change to let insection 11 and the surperficial interlock of prestressing force steel strand 1 of second spacing ring 10 inner wall, first spacing ring 9 and second spacing ring 10 all are used for spacing adjusting nut 8, thereby prevent that adjusting nut 8 breaks away from whole device at the in-process that uses. Thereby enabling the conical adjusting ring 5 to be suitable for more types of steel strands.
In addition, the inventor finds that the existing traction sleeve has the problem of poor connection reliability in the actual working process. When wearing to restraint the work, the torsion of traction steel wire 4 can lead to pulling the screw thread that sheathes in and taking place not hard up, and when prestressing steel strand 1 is longer, the screw thread is not hard up can lead to pulling the cover and taking place to break away from with prestressing steel strand 1, and prestressing steel strand 1 after breaking away from will be stagnated inside the pipe fitting to lead to wearing to restraint work and compelled the termination, and then the efficiency of wearing to restraint work is influenced. In order to solve the problem, the utility model also has the following design.
Referring to fig. 4-5, the pulling assembly includes a pulling plug, a pulling sleeve 12, a coupling sleeve 13, and a tapered pulling head 14; the traction plug is provided with a threading hole 15 for accommodating a prestressed steel strand central wire, one end of the traction sleeve 12 is connected with the traction plug through a connecting sleeve 13, the other end of the traction sleeve 12 is rotatably connected with a conical traction head 14, and the tip end of the conical traction head 14 is connected with one end of the traction steel wire 4.
Specifically, the drawing plug comprises a threaded section 3 and a connecting section 16, an accommodating groove 17 is formed in the side wall of the connecting section 16, and the length direction of the accommodating groove 17 is parallel to the axial direction of the drawing plug; the inner wall of the traction sleeve 12 is provided with a limit strip 18, and the limit strip 18 is inserted into the accommodating groove 17.
The traction assembly further comprises a limiting plate 19, the limiting plate 19 is arranged inside the traction sleeve 12, and the pier head of the center wire of the prestressed steel strand can be fixed through the limiting plate 19; the limiting plate 19 is provided with a mounting hole 20, a connecting bolt 21 is arranged in the mounting hole 20, a connecting hole 22 is arranged on the end face of the connecting section 16, and the connecting bolt 21 is inserted into the connecting hole 22.
Because the prestressed steel strand 1 can be bent when passing through the bent pipe fitting, in order to facilitate the bundle penetration, the connecting bolt 21 is provided with the return spring 23, one end of the return spring 23 is connected with the limiting plate 19, and the other end of the return spring 23 is connected with the screw head of the connecting bolt 21. When the whole prestressed steel strand 1 is bent, the prestressed steel strand 1 positioned outside the bent part will have a large axial movement. At this point, the center wire of the prestressed steel strand will exert a force on the limit plate 19, which force can compress the return spring 23. The compression through reset spring 23 can provide bigger space for the axial float of center wire to make things convenient for prestressing force steel strand 1 to pass through the bending pipe spare.
When the traction steel wire 4 is wound by the winding machine 2, the traction steel wire rotates, and the conical traction head 14 is connected with the traction sleeve 12 in a rotating mode, so that when the conical traction head 14 rotates along with the traction steel wire 4, the conical traction head 14 rotates relative to the traction sleeve 12. Through the process, the traction plug and the traction sleeve 12 can be prevented from loosening, so that the connection stability of the traction assembly and the prestressed steel strand 1 in the penetrating process is improved. The matching of the receiving groove 17 and the limiting strip 18 can prevent the traction sleeve 12 and the traction plug from rotating relatively, so that the possibility of loosening the thread is further reduced.
On the basis of the above scheme, in order to realize the connection between the traction sleeve 12 and the traction plug, the inner wall of the connecting sleeve 13 is provided with internal threads, and correspondingly, the outer wall of the traction sleeve 12 is provided with external threads. During the connection, the internal thread on the inner wall of the connecting sleeve 13 will simultaneously engage with the external thread on the outer wall of the pulling sleeve 12 and the threaded segment 3, so that the pulling sleeve 12 is mounted on the pulling plug.
The device can reduce the loosening probability of the traction assembly through the relative rotation of the traction sleeve 12 and the conical traction head 14, thereby improving the connection reliability of the traction assembly. In addition, this device can make limiting plate 19 have certain elastic displacement ability through reset spring 23, can make things convenient for the steel strand wires to pass the pipe fitting of buckling through this mode, promotes the efficiency of restrainting of wearing of steel strand wires.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
