[0019] 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.
[0020] See also Figure 1-7The utility model provides a technical solution: a pulley device for adjusting a wire rope, comprising a movable plate 1, a fixed plate 3 and a locking member, a slide groove 8 is provided on the side of the fixed plate 3 corresponding to the movable plate 1, a slide rod 7 slidably arranged in the slide groove 8 is provided on the side of the movable plate 1, fixed pulleys 5 are provided at both ends of the movable plate 1 and the fixed plate 3, and limiting pulleys 6 are provided on the outer sides of the movable plate 1 and the fixed plate 3.
[0021] Furthermore, the upper surface of the movable plate 1 is provided with evenly distributed mounting holes 2, and the upper surface of the fixed plate 3 is provided with evenly distributed positioning grooves 4. The locking member includes a screw 91 movably inserted into the mounting hole 2 and an insert rod 93 movably inserted into the positioning groove 4. The top of the screw 91 and the top of the insert rod 93 are connected to the positioning plate 9.
[0022] Furthermore, a nut 92 is threadedly connected to the lower end of the side of the screw rod 91 .

[0024] When using:
[0025] by Figure 7 Take this as an example to illustrate: Figure 7 The trajectory of the wire rope in the initial state:
[0026] When the wire rope needs to be lengthened, the movable plate 1 is moved to the right, and the movable plate 1 drives the slide bar 7 to move a distance along the slide groove 8. At this time, the distance between the movable plate 1 and the fixed plate 3 becomes shorter, that is, the wire rope for external lifting becomes longer, and then the screw rod 91 is inserted into the installation hole 2, and the insertion rod 93 is inserted into the positioning groove 4, and the nut 92 is threadedly connected with the screw rod 91, so as to complete the adjustment and fixation of the wire rope;
[0027] Similarly, when the wire rope needs to be shortened, move the movable plate 1 to the left. From the above steps, it can be seen that the distance between the movable plate 1 and the fixed plate 3 becomes longer, that is, the wire rope for external lifting becomes shorter. Then insert the screw rod 91 into the mounting hole 2, and insert the insert rod 93 into the positioning groove 4, and thread the nut 92 with the screw rod 91 to complete the adjustment and fixation of the wire rope.
