A guide roller 10 is rotatably sleeved on the middle part of the outer ring surface of the limiting shaft 9. Limiting rings are arranged on both sides of the guide roller 10, and the limiting rings are fixedly sleeved on the limiting shaft 9. The guide rollers 10 are symmetrically arranged up and down on the U-shaped frame 8, so that the ropes are guided and limited by the guide rollers 10. The rope fixing mechanism 4 includes a rope cover 11, the top of the rope cover 11 is fixedly connected to the connecting rod, and one side of the bottom of the rope cover 11 is fixedly connected to the connecting plate 12.

[0026] Before use, one end of the rope is passed through the guide rollers 10 symmetrically arranged above and below the U-shaped frame 8. By starting the double-axis driving machine 1, the double-axis driving machine 1 drives the winding drum 5 to rotate under the connection with the rotating shaft 6 to realize the winding and releasing of the rope. During the anchoring process, the rope moves on the guide roller 10, causing the guide roller 10 to rotate under the limit shaft 9, which is conducive to the smooth winding of the rope.

The transverse frame 7 is driven by the sliding seat 18, and the through hole 23 limits the limit shaft 9, thereby facilitating its up and down movement. The buffer spring 24 arranged between the limit shaft 9 and the through hole 23 can reset and buffer the limit shaft 9, and a driving roller 19 is rotatably sleeved between the tops of the two sliding seats 18, and one end of the driving roller 19 is fixedly connected to the output end of the small motor, and the bottom of the small motor is slidably connected to the slide rail, and the slide rail is fixedly connected to the upper surface of the mounting plate 25, and the small motor is connected to the control The devices 15 are electrically connected, the bottom of the two sliding seats 18 are slidably sleeved on the fixed rod 20, the fixed rod 20 limits the sliding seat 18, both ends of the fixed rod 20 are fixedly sleeved in the fixed seat 21, and a driven roller 22 is rotatably sleeved between the two fixed seats 21.

The driving roller 19 meshes with the spiral groove provided on the driven roller 22 through the spiral groove provided on the driving roller 19, thereby driving the driving roller 19 to move along the axial direction of the driven roller 22, so that the sliding seat 18 slides under the limit of the fixed rod 20, driving the horizontal movement of the transverse frame 7, and the transverse frame 7 then drives the U-shaped frame 8 to move horizontally on one side of the winding drum 5. The reciprocating horizontal movement of the transverse frame 7 can be realized by controlling the steering of the small motor, and the guidance of the guide roller 10 can make the rope automatically and evenly coiled, without the need for human protection, and the ropes will not be entangled together, saving time and effort, and can ensure that the ropes are wound. During the process, the rope always remains in the predetermined path to prevent the rope from deviating from the track or winding up. This not only improves the neatness of winding, but also reduces the friction and wear between the ropes, which is convenient for subsequent use. At the same time, the U-shaped frame 8 is connected by the sliding cooperation between the limit shaft 9 and the through hole 23 through the buffer spring 24. When the rope is impacted by an external force, such as sudden tightening, the buffer spring 24 can provide a certain buffering effect on the guide roller 10 to prevent the rope from jumping out of the guide roller 10 due to excessive tension, further avoiding the winding problem. In addition, it is also able to adapt to ropes of different diameters and weights, while ensuring the limiting effect, providing flexible buffering support, which is beneficial to extending the service life of the equipment.
