[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides an electric tail rope take-up device with an adjustable rope guide groove, comprising a frame, a tail rope winding drum arranged in the left and right directions is detachably mounted on the frame, a wire rope take-up and arrangement mechanism arranged parallel to the tail rope winding drum is mounted on the frame directly in front of the tail rope winding drum, the wire rope take-up and arrangement mechanism comprises a wire arrangement device slider (commercially available product), two mounting plates 2 are fixedly arranged on both sides of the wire arrangement device slider, a wire rope guide wheel 18 is rotatably mounted between the mounting plates 2, and a limit pin 1 is matched with the wire rope guide wheel 18 above.

[0020] The limit pin 1 includes a first sleeve 3, a pin rod 5 and a second sleeve 4 which are arranged in sequence from left to right. The first sleeve 3 and the second sleeve 4 are coaxially fixedly installed on the mounting plates 2 on both sides, and the outer ends are both closed structures. The inner ends of the first sleeve 3 and the second sleeve 4 respectively penetrate the corresponding mounting plates 2. The inner walls of the first sleeve 3 and the second sleeve 4 are provided with sliding grooves 301. The two ends of the pin rod 5 are respectively fixedly connected with sliders 501. The two ends of the pin rod 5 are slidably arranged between the sliding grooves 301 of the first sleeve 3 and the second sleeve 4 through the sliders 501.

[0021] One end of the pin rod 5 slides out of the second sleeve 4, and a threaded sleeve 11 is threadedly connected to the protruding end of the pin rod 5. A hollow tubular torque sleeve 6 is fixedly sleeved on the threaded sleeve 11, and one end of the torque sleeve 6 is rotatably connected to the end surface of the second sleeve 4 through an axial bearing 12.

[0022] A reducer 7 located between the mounting plates 2 on both sides is movably sleeved on the outside of the pin rod 5. The annular array of the reducer 7 is divided into at least three ring plates 701. The inside of each ring plate 701 is rotatably connected to the pin rod 5 through a rotatably connected connecting rod 8, and a sliding sleeve 10 is fixedly connected to the inner side of each ring plate 701. A sliding rod 9 is fixedly connected to the position corresponding to each sliding sleeve 10 on the first shaft sleeve 3. One end of the sliding rod 9 is slidably inserted in the sliding sleeve 10 to guide and limit the movement of each ring plate 701.

[0023] That is, the torsion sleeve 6 is twisted clockwise, the pin rod 5 is guided to move toward the first sleeve 3, the push connecting rod 8 is tilted outward, and under the guidance and cooperation of the sliding rod 9 and the sliding sleeve 10, each ring plate 701 moves outward synchronously to form a reducer 7 with a larger outer diameter, so that the reducer 7 is closer to the wire rope guide wheel below, reducing the size of the guide rope groove; conversely, twisting the torsion sleeve 6 counterclockwise increases the groove diameter of the guide rope groove, and then the limit guide of different wire ropes can be adapted under the twisting torsion sleeve 6.

[0024] It should be noted that an inwardly bent rubber belt 702 is glued in the gap between the ring plates 701. The bending design of the rubber belt 702 can deform as the ring plates 701 expand and contract, and fill the gap in the ring plates 701 to prevent the edge of the ring plates 701 from pressing on the outer sheath of the cable and cutting it when rolling. At the same time, it prevents foreign matter such as mud on the outer sheath from invading the interior through the gap between the ring plates 701, causing the structure of the limit pin 1 to move poorly, thereby improving the quality of use.
