Description

Technical Field

[0001] This utility model relates to the field of pullers, and in particular to a hydraulic support pin pulling device. Background Technology

[0002] The hydraulic support pin removal device is a specialized tool designed specifically for the maintenance of hydraulic supports. Its core purpose is to safely and efficiently remove various pins from the support. By providing stable and powerful axial tensile force, it can precisely apply force to the pin to be removed, avoiding damage to the pin and support body caused by traditional hammering and prying methods. It is widely used in hydraulic support maintenance scenarios both underground and on the surface, significantly reducing manual labor intensity and improving the efficiency and safety of pin removal. It is a key auxiliary device to ensure the smooth operation of hydraulic support maintenance.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN211992742U, a positioning pin puller is disclosed, which is guaranteed to be horizontal by a support base. However, in actual use, it has been found that due to the different installation positions of the pins and the need for a force-bearing surface when using the puller, the operating surface of the equipment is affected by various external factors. Furthermore, the process of the pin being pulled out during the pulling process is not linear. When transitions and pauses occur, the support and force-bearing surfaces on both sides are squeezed and offset, which poses a risk of slippage. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic support pin removal device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A hydraulic support pin pulling device includes a pin clamping mechanism for clamping the pin shaft, a lifting mechanism for applying pulling power, a connecting rod adjusting mechanism for supporting both sides, and a stabilizing mechanism. The lifting mechanism includes a screw and a support base. The screw is threaded through and connected to the center of the support base. The bottom of the screw is bolted to the pin clamping mechanism. Both ends of the support base are fixedly connected to the connecting rod adjusting mechanism. The stabilizing mechanism is fixedly connected to the bottom of the connecting rod adjusting mechanism. The lifting mechanism also includes a spacing adjustment seat and a side rod. The spacing adjustment seat is bolted to the support seat, and the side rod is bolted to the bottom of the spacing adjustment seat. The linkage adjustment mechanism includes an adjustment sleeve and an adjustment rod. The adjustment sleeve is fixed to the bottom of the side rod, and the adjustment rod is threaded to the adjustment sleeve. The stabilizing mechanism includes a swing seat and a base. The swing seat is a semi-cylindrical structure. The arc-shaped surface at the bottom of the swing seat corresponds to and engages with the arc-shaped groove on the base. The swing seat is engaged with the two sides of the base by anti-detachment components. A force-bearing seat is engaged with the bottom of the base by a follow-up component. An anti-slip pad is installed on the bottom surface of the force-bearing seat. Several magnets are embedded in the anti-slip pad. The force-bearing seat is engaged with the two sides of the bottom of the swing seat by sliding strips.

[0006] Preferably, the anti-detachment component includes a limiting groove and a limiting rod. The two sides of the swing seat are formed with arc-shaped limiting grooves, and the limiting rod is fixedly connected to the side of the base. The limiting rod is snapped into the limiting groove.

[0007] Preferably, the follower component includes a mating gear and a mating rack. The mating gear is formed on the arc-shaped surface of the bottom of the swing seat, and the mating rack is mated to the bottom of the mating gear.

[0018] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, a hydraulic support pin pulling device includes a pin clamping mechanism 2 for clamping the pin shaft, a lifting mechanism 1 for applying pulling power, a connecting rod adjusting mechanism 3 for supporting both sides, and a stabilizing mechanism 4. The lifting mechanism 1 includes a screw 11 and a support seat 12. The screw 11 is threaded through and connected to the center of the support seat 12. The bottom of the screw 11 is bolted to the pin clamping mechanism 2. The connecting rod adjusting mechanism 3 is fixedly connected to both ends of the support seat 12. The stabilizing mechanism 4 is fixedly connected to the bottom of the connecting rod adjusting mechanism 3. The lifting mechanism 1 also includes a spacing adjustment seat 13 and a side rod 14. The spacing adjustment seat 13 is connected to the support seat 12 by bolts, and the side rod 14 is connected to the bottom of the spacing adjustment seat 13 by bolts. The linkage adjustment mechanism 3 includes an adjustment sleeve 31 and an adjustment rod 32. The adjustment sleeve 31 is fixedly connected to the bottom of the side rod 14, and the adjustment rod 32 is connected to the adjustment sleeve 31 by a thread. The stabilizing mechanism 4 includes a swing seat 41 and a base 42. The swing seat 41 is a semi-cylindrical structure. The arc-shaped surface at the bottom of the swing seat 41 corresponds to and engages with the arc-shaped groove on the base 42. The swing seat 41 is engaged on both sides of the base 42 through anti-detachment components. A force-bearing seat 45 is engaged at the bottom of the base 42 through a follower component. An anti-slip pad 46 is installed on the bottom surface of the force-bearing seat 45. Several magnets 47 are embedded in the anti-slip pad 46. The force-bearing seat 45 is engaged on both sides of the bottom of the swing seat 41 through a slider 423.

[0019] In this embodiment, the anti-detachment component includes a limiting groove 421 and a limiting rod 422. The swing seat 41 has arc-shaped limiting grooves 421 formed on both sides. The limiting rod 422 is fixedly connected to the side of the base 42. The limiting rod 422 is snapped into the limiting groove 421. By using the limiting, the flipping limit is avoided and the stability of the flipping process is ensured.

[0020] In this embodiment, the follower component includes a mating gear 43 and a mating rack 44. The mating gear 43 is formed on the arc-shaped surface of the bottom of the swing seat 41, and the mating rack 44 is mated to the bottom of the mating gear 43. The mating rack 44 is horizontally installed on the inner bottom surface of the force-bearing seat 45. By meshing, it shifts to the opposite side during the flipping process.

[0021] In this embodiment, an adjusting screw 5 is installed on the side of the force-bearing seat 45 to adjust the position of the mating rack 44. The adjusting screw 5 is rotatably connected to the force-bearing seat 45 through an anti-detachment ring, and the mating rack 44 is slidably connected to the force-bearing seat 45.

[0022] In this embodiment, the swing amplitude of the swing seat 41 relative to the base 42 is 0° to 30°.

[0023] In this embodiment, the clamping mechanism 2 includes a central cap 21, a clamping seat 22, and a clamping screw 23. The central cap 21 is connected to the screw rod 11 by bolts. The clamping seat 22 and the central cap 21 are integrally formed. The clamping screw 23 is connected to the clamping seat 22 by threads.

[0024] In this embodiment, four clamping screws 23 are provided and are mounted in a circumferential array on the clamping base 22.

[0025] Working principle: When using, adjust the length of the adjusting rod 32 and the initial angle of the force seat 45 according to the site to be used. If it is used on a flat surface and is not easy to slip, just make sure that the swing seat 41 and the base 42 are relatively parallel. Support the connecting rod adjusting mechanism 3 and the stabilizing mechanism 4 on the construction platform, adjust the clamping screw 23 to clamp the pin to be removed, and rotate the screw 11 to pull out the pin using the support on both sides. When the operating environment has an incline or is prone to slippage, first adjust the position of the meshing rack 44 using the adjusting screw 5. At this time, because the meshing gear 43 and the meshing rack 44 are engaged, the swing seat 41 and the base 42 will be adjusted accordingly. First, use the magnet 47 to attract the pin to the operating surface, and then use the clamping pin mechanism 2 to clamp the pin. Rotate the screw 11 to pull out the pin. At this time, because the side rod 14 and the adjusting rod 32 are tilted, a slight slippage may occur during the application of force. When slipping, the swing seat 41 and the base 42 will rotate relative to each other through the meshing gear 43 and the meshing rack 44. The meshing gear 43 and the meshing rack 44 will mesh and rotate in the opposite direction to the slippage. The meshing gear 43 and the meshing rack 44 will engage in the opposite direction to the slippage through rotation, thereby ensuring the pressure between the force-bearing seat 45 and the force-applying surface, thus avoiding further slippage and ensuring safety.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
