[0002] Steel strand tractors are mainly used in projects such as road and bridge, municipal, high-rise building, power station construction, geotechnical anchorage, deep foundation pit support, etc. In addition, in road traffic emergency rescue, steel strand tractors are also widely used in the traction of finished steel strand bundles. Especially when passing through the construction duct corrugated pipe, it can avoid the winding and torsion between steel strands.

[0003] The existing patent CN213806639U discloses a steel strand tractor. The front end of the steel strand passes through the pipe hole of the first steel pipe element. Further, the steel strand passes through the second steel pipe element, and the surface of the second steel pipe element is galvanized, effectively avoiding the corrosion of the second steel pipe element due to rainwater, thereby prolonging the service life of the second steel pipe element. Then, two clamping pieces are placed on the surface of the steel strand and the clamping pieces are fixed by a fixing wire to prevent falling off. Further, by pulling the top end of the traction ring with a winch, the steel strand can be effectively traction, avoiding manual traction. A protection pad is fixedly arranged inside the top end of the traction ring, effectively reducing the wear inside the top end of the traction ring, thereby prolonging the service life of the tractor. During the traction process, the steel strand can rotate inside the tractor to break the stress during the steel strand traction, and the tractor is suitable for the traction of steel strands of different lengths.

[0004] When the existing device fixes the steel strand, it can only be fixed by clamping pieces. When the pulling force on the steel strand is large, the steel strand is likely to fall off from the clamping pieces. Content of the Utility Model

[0005] The purpose of the utility model is to provide a steel strand tractor to solve the problem that when the steel strand can only be fixed by clamping pieces and the steel strand is likely to fall off from the clamping pieces when the pulling force on the steel strand is large.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a steel strand tractor, including a traction ring, a first fixing cylinder is arranged at the end of the traction ring, a circular ring is rotatably connected inside the first fixing cylinder, rotating rings are fixed on both sides of the circular ring, a plurality of arc-shaped plates are fixed on the inner wall of the circular ring. Rotating the rotating ring drives the circular ring to rotate, and the circular ring drives the arc-shaped plates to rotate. Fixing plates are arranged on both sides inside the circular ring. A plurality of sliding grooves are arranged on the outer side of one side of the fixing plate. Arc-shaped block plates are slidably connected inside the sliding grooves. When the arc-shaped plates rotate, they squeeze a plurality of arc-shaped block plates to move closer to the position of the steel strand through the sliding grooves, so that the arc-shaped block plates fix steel strands of different sizes.

[0007] As a further solution of the present utility model: a steel strand is arranged inside the arc-shaped block plate, and a second fixing cylinder is arranged on one side of the first fixing cylinder outside the steel strand.

[0008] As a further solution of the present utility model: a first groove is arranged on one side inside the second fixing cylinder, a semi-conical column is fixed on the surface of the steel strand, and the outside of the semi-conical column is inside the first groove, and a semi-conical column is arranged outside the steel strand.

[0009] As a further solution of the present utility model: a second groove is arranged outside the semi-conical column, and two groups of semi-conical columns are arranged. When the steel strand is pulled, the steel strand will pull the semi-conical column to move inside the first groove, so that the outside of the semi-conical column is squeezed by the first groove, thereby making the semi-conical column fix the steel strand more firmly.

[0010] As a further solution of the present utility model: a fixing ring is arranged inside the second groove, the outside of the semi-conical column is inside the first groove, and the outside of the semi-conical column is in contact with the inner wall of the first groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] 1. By setting the ring to drive the arc-shaped plate to rotate, when the arc-shaped plate rotates, it squeezes a plurality of arc-shaped block plates to move closer to the position of the steel strand through the sliding groove, so that the arc-shaped block plates fix steel strands of different sizes.

[0013] 2. By setting the outside of the semi-conical column to be inside the first groove, when the steel strand is pulled, the steel strand will pull the semi-conical column to move inside the first groove, so that the outside of the semi-conical column is squeezed by the first groove, thereby making the semi-conical column fix the steel strand more firmly.
