DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a mining machinery and equipment pay-off frame, including a base 1, a support leg 2 is connected below the base 1, a rubber pad 24 is connected below the support leg 2, and the anti-skid pad 23 and the rubber pad 24 are both provided with anti-skid patterns. The rubber pad 24 under the support leg 2 increases the friction with the ground, thereby preventing the base 1 from sliding when the cable is pulled, and the anti-skid pads 23 on both sides of the plug block 18 can facilitate the staff to take and remove the plug block 18 to prevent the plug block 18 from slipping.

[0022] Support rods 3 are connected to both sides of the base 1, and a support platform 4 is slidably installed on the base 1 through the support rods 3. Slide grooves 5 are opened on both sides above the base 1, and smooth rods 6 are connected inside the slide grooves 5. Reset springs 12 are sleeved on both ends of the smooth rod 6, one end of the reset spring 12 is connected to the inner wall of the base 1, and the other end of the reset spring 12 is connected to the slider 7. A buffer spring 13 is connected to the support rod 3, and one end of the buffer spring 13 is connected to the support platform 4. The impact caused by the vibration is buffered multiple times by compressing the reset spring 12 and the buffer spring 13, thereby avoiding loosening of parts due to excessive impact force.

[0023] A slider 7 is slidably connected to the smooth rod 6, and a pin shaft 8 is connected to the slider 7. The slider 7 is rotatably connected to a damper 9 through the pin shaft 8. One end of the damper 9 is rotatably connected to a connecting block 10 through the pin shaft 8. A shock-absorbing spring 11 is connected to the damper 9. The connecting block 10 is connected to the bottom of the support platform 4. When the support platform 4 moves downward, the slider 7 is pushed to move through the damper 9, and the shock-absorbing spring 11 and the damper 9 are compressed at the same time, thereby buffering and reducing the vibration generated when the cable is pulled, thereby improving the working stability of the pay-off rack.

[0024] A support frame 14 is connected to the support platform 4, and a wire roller 25 is rotatably installed between the two support frames 14. A mounting groove 15 is provided on the support frame 14, and a clamping groove 16 is provided on the inner wall of the mounting groove 15. A connecting groove 17 is provided in the mounting groove 15. An insert block 18 is slidably installed on the support frame 14 through the connecting groove 17. A groove 20 is provided inside the insert block 18, and a connecting spring 21 is connected in the groove 20. A clamping block 22 is connected to one end of the connecting spring 21. The clamping block 22 is triangular in design and is engaged with the clamping groove 16. The engagement of the clamping block 22 with the clamping groove 16 allows the insert block 18 to be fixed in the mounting groove 15, thereby limiting the wire roller 25 and preventing the wire roller 25 from falling out of the mounting groove 15 due to rapid rotation. The triangular design of the clamping block 22 allows the clamping block 22 to be easily pushed by the outer wall of the support frame 14.

[0025] A connecting strip 19 is connected to the plug block 18, and anti-slip pads 23 are connected to both sides of the plug block 18. The connecting strip 19 is T-shaped and slides in the connecting groove 17. The lower end of the plug block 18 is arc-shaped, and an inclined surface is provided above the support frame 14 near the card slot 16. Through the sliding of the connecting strip 19 in the connecting groove 17, the staff can easily and quickly position and install the plug block 18 and prevent the plug block 18 from tilting in the installation groove 15.

[0026] The working principle of the utility model is:

[0027] After placing both ends of the wire roller 25 in the mounting groove 15, align the connecting strip 19 with the connecting groove 17 so that the plug block 18 can be inserted into the mounting groove 15. As the plug block 18 is inserted, the card block 22 will be pushed into the groove 20 by the outer wall of the support frame 14, compressing the connecting spring 21. After the plug block 18 contacts the wire roller 25, the connecting spring 21 rebounds and pushes the card block 22 to be stuck in the card groove 16, thereby fixing the plug block 18 on the support frame 14 to prevent the wire roller 25 from falling out of the mounting groove 15 due to rapid rotation. When the cable is pulled to rotate the wire roller 25, the support platform 4 will move along the support rod 3 due to vibration, thereby compressing the buffer spring 13 to buffer the impact caused by the vibration, and when the support platform 4 moves downward, the slider 7 will be pushed to move on the smooth rod 6 through the damper 9. At the same time, the support platform 4 will compress the shock-absorbing spring 11 and the damper 9 to buffer and weaken the vibration. When the slider 7 moves, the reset spring 12 will be compressed, thereby further buffering the impact.
