[0022] See also Figures 1 to 3 The utility model provides an adjusting device for a rope of a lifting device, the adjusting device comprises a mounting body 100, a rope body 200, a fixing part 300 and an adjusting block 400. A stopper 210 is fixedly arranged at the end of the rope body 200, and the stopper 210 is arranged at one side of the mounting body 100; the fixing part 300 is fixedly arranged at a side of the mounting body 100 away from the stopper 210; the adjusting block 400 is located at a side of the fixing part 300 facing the stopper 210, and the adjusting block 400 abuts against the stopper 210; wherein, a channel 110 for the adjusting block 400 to slide is arranged on the mounting body 100, and the adjusting block 400 can slide back and forth along the channel 110 toward the fixing part 300. The adjusting block 400 and the fixing part 300 are both provided with through holes for the rope body 200 to slide through. One end of the rope body 200 is fixed to the stopper 210, and the other end (i.e., the lifting end) sequentially passes through the through hole on the adjusting block 400, the channel 110 on the mounting body 100, and the through hole on the fixing part 300, and is extended out and connected to the weight to be lifted after being wound by a reel. When lifting multiple ropes, the adjusting device of the utility model can be installed at the fixed end (i.e., the end opposite to the lifting end) of each rope. When in use, the fixing part 300 is fixedly connected to the mounting body 100 (the frame or building of the lifting equipment, or other fixing parts), and the lifting end of the rope is connected to the weight to be lifted after being wound by a reel. When the rope is unevenly stressed, the length can be adjusted by sliding the rope, so that the stress conditions of multiple ropes on the lifting device can be made the same.

[0023] See also Figures 1 to 3, in one embodiment, the fixing portion 300 includes a side wall 310 and a top plate 320 disposed circumferentially along the side wall 310. One end of the side wall 310 abuts against the mounting member body 100, and the other end of the side wall 310 is fixedly connected to the top plate 320. A through hole for the rope to slide through is provided at the center of the top plate 320. In this embodiment, the fixing portion 300 and the mounting member body 100 are fixedly connected by a fastener 500. The fastener 500 includes a locking bolt 510 and a locking nut 520. The locking bolt 510 sequentially passes through the mounting member body 100, the side wall 310, and the top plate 320 and is fixedly connected to the locking nut 520. Further, a stop washer 530 is disposed between the locking nut 520 and the top plate 320. The stop washer 530 is sleeved on the locking bolt 510 and used in cooperation with the locking nut 520 to prevent the locking nut 520 from loosening by providing elastic deformation and friction force, thereby improving the stability and service life of the adjusting device. Furthermore, a groove 120 is provided on the side of the mounting member body 100 facing away from the fixing portion 300, and the head of the locking bolt 510 is disposed in the groove 120. Embedding the head of the locking bolt 510 into the groove 120 can not only provide better stability and prevent the head of the locking bolt 510 from rotating or moving when stressed, but also avoid the head of the locking bolt 510 from being accidentally touched or impacted, preventing damage or snagging caused by the protruding part.

[0024] Please refer to Figures 1 to 3 , in one embodiment, an adjusting bolt 321 and an adjusting nut 322 are provided on the top plate 320. The adjusting bolt 321 sequentially passes through the adjusting nut 322 and the top plate 320 and abuts against the adjusting block 400. Adjusting the protruding length of the adjusting bolt 321 on the top plate 320 can adjust the distance between the adjusting block 400 and the top plate 320. Specifically, by tightening the adjusting bolt 321, the adjusting block 400 can be pushed to slide in a direction away from the top plate 320. The adjusting block 400 presses the stop block 210, and the stop block 210 drives the rope to move in a direction away from the fixing portion 300, reducing the length of the rope outside the adjusting device. By loosening the locking bolt 510 and dragging the rope, the stop block 210 drives the fixing portion 300 to move in a direction close to the top plate 320, increasing the length of the rope outside the adjusting device. The length of the rope outside the adjusting device can be adjusted by the sliding of the rope body 200, so that one end (i.e., the lifting end) of each rope facing away from the stop block 210 is at the same height, ensuring that the forces on multiple ropes are the same.

[0025] Please refer to Figures 1 to 3In one embodiment, the adjusting block 400 is cylindrical, and the inner wall of the channel 110 is in contact with the outer wall of the adjusting block 400. In this embodiment, the stopper 210 is conical, and the adjusting block 400 is provided with a conical through hole 410 matching the stopper 210, and the side wall 310 of the conical through hole 410 is in contact with the outer wall of the stopper 210. The conical stopper 210 cooperates with the conical through hole 410 of the adjusting block 400 to not only automatically align, but also reduce the shaking of the rope and reduce the wear on the rope.

[0026] See also Figures 1 to 3 In one embodiment, the fixing portion 300 is cylindrical, and a positioning groove 130 for positioning the fixing portion 300 is provided on one side of the mounting member body 100 facing the fixing portion 300, and the outer wall of the fixing portion 300 abuts against the inner wall of the positioning groove 130. The positioning groove 130 can prevent the fixing portion 300 from deviating in its radial direction, avoid friction between the fixing portion 300 and the rope body 200, and reduce wear on the rope body 200.
