[0002] In the steel production industry, cold-rolled ribbed steel bars are made from ordinary low-carbon hot-rolled high-speed wire rod. During the production and transportation process, cold-rolled ribbed steel bars require a traction device for pulling.

[0003] Utility Model Publication No. CN205421952U discloses a rebar traction device, which includes a traction mechanism and a conveying mechanism. The traction mechanism includes a traction vehicle, a traction rail, and a traction plate. The traction vehicle is located on the traction rail, and the traction plate is mounted on the traction vehicle. The traction plate is provided with several rebar clamping mechanisms to facilitate the simultaneous clamping of the front ends of multiple rebars to be dragged. In addition, the conveying mechanism consists of multiple conveying units arranged in a front-to-back manner, and each conveying unit has multiple horizontal support shafts and sliding bushings that cooperate with the horizontal support shafts on its conveying support bracket. Several annular rebar placement grooves are provided on the surface of the sliding bushings, and the rebars are placed in the annular rebar placement grooves. The cooperation between the sliding bushings and the horizontal support shafts helps to save the pulling force required when dragging the rebars. This utility model, through the coordinated operation of the traction mechanism and the conveying mechanism, helps to improve the dragging efficiency of rebars and save manpower and time.

[0026] When it is necessary to pull large steel bars of different diameters, the positioning bolt 19 can be loosened first, and then the support screw 11 can be rotated in conjunction with the limit bearing 10, so that the moving plate 12 can be displaced, and then the positioning ring 13 can be displaced. The distance between the positioning ring 13 and the baffle 8 can be adjusted, so that steel bars of different diameters can be pulled conveniently.

[0027] Example 2: Based on Example 1, a traction rod 7 is provided to facilitate the traction of the reinforcing bars. The drive motor 6 is fixedly connected to the surface of the base plate 5. Two sets of support shafts 4 are provided. The end faces of the two sets of support shafts 4 are fitted with drive gears 14. The two sets of drive gears 14 are driven by a toothed belt 15. The transmission end of the drive motor 6 is fixedly connected to the end face of one set of support shafts 4. The support shafts 4 are fixedly connected to the inner ring surface of the positioning bearing 2. The support shafts 4 pass through the support frame 1. The support rod 3 is fixedly connected to the inner ring surface of the positioning bearing 2.

The traction frame 22 is an "F" shaped plate structure. The traction frame 22 limits the toothed belt 15.

[0028] In use, the drive motor 6 can be started to drive a set of support shafts 3 to rotate. Then, the toothed belt 15 can be used to drive two sets of drive gears 14 to rotate. Then, the traction rod 7 set at one end of the support shaft 4 can rotate, which can facilitate the traction of the steel bars. The traction frame 22 can limit the toothed belt 15 to prevent it from disengaging from the drive gears 14.

[0029] Example 3: Based on Example 2, a positioning ring 13 is provided to facilitate the traction of steel bars of different diameters. A baffle 8 is fixedly connected to the surface of the traction rod 7. The baffle 8 has an annular plate structure. A guide opening 16 is provided on the surface of the moving groove 9.
