DETAILED DESCRIPTION The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0010] like Figure 1-3As shown, a hydraulic brake cable pay-off frame suitable for different specifications includes a support frame 1, which is placed symmetrically on the left and right. Columns 2 are symmetrically installed and fixed on both sides of the middle of the support frame 1 by screws. A first screw rod 3 is integrally formed in the middle of the column 2 and connected. An adjusting nut 4 and a base 5 are arranged on the first screw 3. The adjusting nut 4 is connected to the bottom of the first screw rod 3 by thread. The base 5 is sleeved on the lower end of the first screw 3. A jack 6 is fixed to the middle of the top of the base 5 by screws. A base 7 is fixed to the top of the piston rod of the jack 6 by screws. The base 7 is sleeved on the first screw 3. A lifting seat 8 is fixed to the middle of the top of the base 7 by screws. Lifting pulleys are connected to the two sides of the top of the lifting seat 8 by rotating shafts. 9. A disc shaft 10 is placed on the top of the lifting pulley 9. A second screw 11, a limit plate 12 and a brake disc 13 are arranged on the disc shaft 10. The second screw 11 is integrally connected to the middle of the disc shaft 10. The limit plate 12 is symmetrically installed and fixed to both ends of the disc shaft 10 by screws, and the limit plate 12 is in contact with the inner side of the lifting seat 8. The brake disc 13 is installed and fixed to the right end of the disc shaft 10 by screws. A fastening nut 14 is symmetrically connected to the second screw 11 through threads. A fastening conical block 15 is integrally connected to the inner end of the fastening nut 14. A hydraulic brake caliper 16 is set on the outer side below the brake disc 13. A bracket 17 is installed and fixed to the inner end of the hydraulic brake caliper 16 by screws. The bracket 17 is fixedly connected to the corresponding base 7 by screws.

[0011] Specific usage: put the disc shaft 10 on the center hole of the cable drum, then symmetrically screw the fastening nut 14 on the second screw 11, and the fastening conical block 15 squeezes and fixes the two sides of the center hole of the cable drum under the drive of the fastening nut 14. At this time, the cable drum is fixed on the disc shaft 10; then move the two ends of the disc shaft 10 to the top of the corresponding lifting pulley 9, and place the brake disc 13 directly above the top of the hydraulic brake caliper 16, and at the same time move the limit plate 12 to the inside of the corresponding lifting seat 8, and fix the limit plate 12; at this time, screw the adjusting nut 4 to drive the base 5 to slide upward along the first screw 3, and the base 5 slides upward to drive the base The lifting seat 8 on 7 slides upward, and the lifting seat 8 slides upward to drive the lifting pulley 9 to contact the disc shaft 10. At the same time, the hydraulic brake caliper 16 is installed under the brake disc 13 under the drive of the base 7; then the jack 6 is manually controlled to lift the base 7. After the base 7 is lifted, it drives the disc shaft 10 to slide upward along the first screw 3. The disc shaft 10 slides upward and drives the cable drum to slide upward and separate from the ground; then the hydraulic brake caliper 16 is connected to the external hydraulic station through the hydraulic control valve; when the cable drum rotates to release the wire, the hydraulic brake caliper 16 and the brake disc 13 can cooperate to brake the disc shaft 10 to adjust the cable drum release speed.
