Description

Technical Field

[0001] The invention relates to the technical field of dismantling equipment, in particular to a hydraulic support dismantling equipment. Background Art

[0002] A hydraulic support is a supporting device that adjusts its height through a hydraulic system and is widely used in industries such as coal mines and tunnels. When a hydraulic support is used as a supporting equipment in a coal mining face, it is usually used in sets of dozens to hundreds of units. After a period of use, the hydraulic support needs to be maintained. The most important step in maintenance is the disassembly of the hydraulic support, and the most time-consuming and labor-intensive part of the disassembly process is the disassembly of the articulated pins, such as the disassembly of the articulated pins between the top beam and the cover beam, and the disassembly of the articulated pins between the connecting rod and the base.

[0003] When disassembling the hinged pin shaft of the existing hydraulic support, the hinged pin shaft is often pushed out by a hydraulic rod. During the pushing process, the hydraulic support will shake. When the hydraulic support shakes, the force pushing the pin shaft will act unevenly on the pin shaft, causing the pin shaft to deflect during the pushing process. The deflection of the pin shaft will cause the bearing or other related mechanical parts to bear abnormal lateral force and torque; it will not only accelerate the wear or damage of the bearing, but also easily cause the pin shaft to bend, thereby increasing the difficulty of removing the pin shaft; therefore, during the disassembly of the hydraulic support, the hydraulic support needs to be fixed on the disassembly table.

[0004] In the process of disassembling the existing hydraulic supports, iron chains are mostly used to fix the hydraulic supports. This is because the iron chains are relatively flexible when used and can freely surround the supports and workbenches to adapt to different work requirements and space restrictions. Moreover, compared with other clamping devices, the fixing force applied by the iron chains is relatively uniform and can adapt to supports of different shapes and sizes. For the fixation of large hydraulic supports, thicker iron chains are usually used to ensure stability and safety during the disassembly process. For this, a crane is often used to lift one end of the iron chain and pass it over the hydraulic support, so that the thicker iron chain can bind the hydraulic support to the disassembly workbench. However, before binding the iron chain to the crane, it is necessary to first remove the steel cable connecting the crane and the hydraulic support, and then bind the iron chain. When the disassembly is completed, the steel cable needs to be hung on the crane again, thereby increasing the overall disassembly time, especially in the process of disassembling large quantities of hydraulic supports, reducing work efficiency, and the steel cables used in large hydraulic supports are relatively thick and heavy, and repeated disassembly and installation of the steel cables will increase the labor intensity of the staff. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, the present invention proposes a hydraulic support disassembly equipment.

[0036] The mounting frame 2 comprises:

[0037] The support frame 23 is provided with two groups; the two groups of the support frames 23 are distributed on both sides of the body 1; the support frame 23 is provided with a mounting groove 231 on one side close to the support plate 11; a mounting plate 232 is slidably connected in the mounting groove 231; a hinged rod 233 is rotatably connected to the upper end of the mounting plate 232; the slide groove 21 is provided on the side of the hinged rod 233 away from the support frame 23; two support rods 18 are provided between the two hinged rods 233, one of the support rods 18 is fixedly connected to the disassembly platform 13, and the other support rod 18 is fixedly connected to the baffle 12;

[0041] In the process of disassembling the existing hydraulic supports, iron chains are mostly used to fix the hydraulic supports. This is because the iron chains are relatively flexible when used and can freely surround the supports and workbenches to adapt to different work requirements and space restrictions. Moreover, compared with other clamping devices, the fixing force applied by the iron chains is relatively uniform and can adapt to supports of different shapes and sizes. For the fixation of large hydraulic supports, thicker iron chains are usually used to ensure stability and safety during the disassembly process. For this, a crane is often used to lift one end of the iron chain and pass it over the hydraulic support, so that the thicker iron chain can bind the hydraulic support to the disassembly workbench. However, before binding the iron chain to the crane, it is necessary to first remove the steel cable connecting the crane and the hydraulic support, and then bind the iron chain. When the disassembly is completed, the steel cable needs to be hung on the crane again, thereby increasing the overall disassembly time, especially in the process of disassembling large quantities of hydraulic supports, reducing work efficiency, and the steel cables used in large hydraulic supports are relatively thick and of medium quality. Repeated disassembly and installation of the steel cables will increase the labor intensity of the staff.

[0042] In the initial state, the hinge rod 233 is located in the mounting groove 231 of the support frame 23 and the lower end of the support frame 23 is rotatably connected with the ball 236, so the user pushes the support frame 23 to move in the direction close to the fixing frame 19, so that the support frame 23 can roll on the ground through the ball 236 until the support frame 23 enters the U-shaped groove of the fixing frame 19, so that the support frame 23 can be closely attached to the body 1, and at this time, the ear 235 of the support frame 23 is opposite to the bolt hole 191, and the bolt 192 is inserted into the bolt hole 191, so that the bolt 192 inserted into the bolt hole 191 can be inserted into the bolt hole 191. 92 can pass through the hanging ear 235, the bolt 192 fixes the support frame 23 in the fixing frame 19, and the nut is tightened so that the bolt 192 fixes the support frame 23 and the fixing frame 19, and then the wire rope 161 of the clamping assembly is fixedly connected to the cylinder 16, and the connection between the mounting frame 2 and the machine body 1 is completed at this time; since the clamping block 221 is located at one end of the slide 21 close to the fixing frame 19; since the output end of the hydraulic push rod 15 is connected to a locking hook, the hydraulic push rod 15 is in an extended state, and the chain link at one end of the iron chain is buckled into the locking hook, so that the locking hook can lock the iron chain;

[0043] Then, the electromagnetic sheets 222 on the side of the two clamping plates 22 that are close to each other are controlled to be energized, so that the two electromagnetic sheets 222 generate the same electrode, so that the two electromagnetic sheets 222 are driven by the magnetic repulsion force to push the two clamping blocks 221 to rotate in the direction away from each other, so that the two clamping blocks 221 are opened, and at this time, the two chain links at the other end of the iron chain are sleeved on the two plug rods 223 located below; one of the electromagnetic sheets 222 is controlled to be de-energized, and at this time, the other energized electromagnetic sheet 222 adsorbs the two clamping blocks 221 to approach each other and can clamp the chain links; and at this time, the chain links at one end of the iron chain clamped by the clamping blocks 221 extend out of the two clamping blocks 221, and the upper and lower groups of plug rods 223 limit the chain links;

[0044] At the same time, the upper and lower groups of plug rods 223 can clamp the chain ring on the lower plug rod 223 to reduce the chain ring shaking, so as to ensure that the clamping block 221 can stably clamp the chain ring for transportation; then the user uses a crane to place the hydraulic support to be disassembled on the support plate 11, and at this time the transmission unit is controlled to be disconnected, so that the cylinder 16 and the drive motor 17 are in a separated state, while the drive motor 17 is in a connected state with the bevel gear shaft 242, and the drive motor 17 is controlled to rotate so that the drive motor 17 can drive the bevel gear shaft 242 to rotate, so that the bevel gear shaft 242 can drive the bevel gear ring 241 meshing with it to rotate, and since the bevel gear ring 241 is fixedly connected to the screw rod 234, the bevel gear ring 241 can drive the screw rod 234 to rotate synchronously, so that the screw rod 234 drives the mounting plate 232 connected to its spiral transmission to rotate upward along the mounting groove 231, so that when the mounting plate 232 slides upward, the mounting plate 232 can push the hinged rod 233 connected to the upper end to rise;

[0045] Since the flange 251 is fixedly connected to the side wall of the hinge rod 233, the flange 251 can limit the hinge rod 233 in the installation groove 231, thereby preventing the hinge rod 233 in the installation groove 231 from rotating due to the center of gravity offset; during the rising process of the hinge rod 233, the hinge rod 233 drives the clamping plate 22 in the sliding groove 21 on one side to rise synchronously, so that the clamping plate 22 drives one end of the iron chain clamped by the clamping block 221 to rise, until the flange 251 on the surface of the hinge rod 233 drives the iron chain out of the installation groove 231. Since the clamping block 221 clamps the iron chain, the iron chain is connected to the clamping block 221, so that the gravity of the iron chain generates an inclined pulling force on the hinge rod 233. At this time, the hinge rod 233 at the upper end of the installation plate 232 rotates downward under the pull of the iron chain;

[0046] Since two support rods 18 are arranged between the two hinged rods 233, one of the support rods 18 is fixedly connected to the disassembly platform 13, and the other support rod 18 is fixedly connected to the baffle 12, the hinged rod 233 rotating downward can fall onto the support rod 18 adjacent thereto, so that the support rod 18 can support the hinged rod 233, so that the two opposite support rods on one side of the machine body 1 can be in a horizontal alignment state, and at this time, the rising height of the mounting plate 232 is the maximum;

[0047] Then, the transmission unit is controlled to be connected, so that the cylinder 16 is connected to the drive motor 17, and the bevel gear shaft 242 is separated from the output shaft of the drive motor 17. At this time, the drive motor 17 is controlled to drive the cylinder 16 to rotate, so that the two cylinders 16 can pull the two clamping plates 22 along the slide 21 to move toward each other through the steel wire rope 161 fixed thereto under the drive of the drive motor 17. The clamping block 221 at the lower end of one clamping plate 22 clamps the iron chain, while the clamping block 221 at the lower end of the other clamping plate 22 is in an open state until the two clamping blocks 221 touch each other, and at this time, the two clamping blocks 221 are close to the disassembly table 13. The chain link clamped by the two clamping blocks 221 leaks out half, so that the leaking part of the chain link is located between the two clamping blocks 221 close to the baffle 12. At this time, by controlling one of the electromagnetic sheets 222 in the two clamping blocks 221 close to the baffle 12 to be energized, the two clamping blocks 221 close to the baffle 12 clamp the leaking part of the chain link under the adsorption of the electromagnetic sheets 222, and controlling the electromagnetic sheets 222 of the two clamping blocks 221 close to the disassembling platform 13 to be energized, so that the two clamping blocks 221 close to the disassembling platform 13 rotate in a direction away from each other, so that the two clamping blocks 221 close to the disassembling platform 13 are opened;

[0048] The opened clamp block 221 drives the connected plug rod 223 to rotate upward, so that the plug rod 223 tilts downward. At this time, the chain link will slide down along the tilted plug rod 223 under the action of gravity. At this time, the driving motor 17 is controlled to rotate in the opposite direction, so that the steel wire rope 161 wound on the surface of the cylinder 16 is released, and the clamping plates 22 in the two opposite slide grooves 21 move away from each other in the opposite direction under the push of the support spring 211, so that the clamp block 221 close to the baffle 12 clamps the iron chain and passes over the top of the hydraulic support;

[0049] Until the steel wire ropes 161 on the surfaces of the two cylinders 16 are completely released, at which time the two sliders are located at the two ends of the two slide slots 21 that are away from each other; at this time, the clamping block 221 close to the baffle 12 is controlled to separate, so that the clamped iron chain falls under the action of gravity, and at this time the user pulls the iron chain over one end of the hydraulic support and hangs it on the hook 14 below, and controls the hydraulic push rod 15 in the extended state to contract, so that the hydraulic push rod 15 pulls the iron chain connected to the hook 14 to straighten, so that the straightened iron chain can tie the hydraulic support to the support plate 11, thereby improving the stability of the hydraulic support disassembly;

[0050] When the disassembly is completed, the user controls the hydraulic push rod 15 to extend so that the stretched iron chain is released, and then removes the end of the iron chain connected to the hook 14 from the hook 14, and then controls the crane to lift the hydraulic support, and lifts the hydraulic support to the middle of the two articulated rods 233, and then controls the crane again to pull the hydraulic support up, so that the raised hydraulic support can push the two articulated rods 233 to rotate away from each other, and at the same time, controls the driving motor 17 to drive the mounting plate 232 to descend along the mounting groove 231, so that the mounting plate 232 drives the upwardly rotating articulated rod 233 to descend, and descends with the articulated rod 233;

[0051] The hinge rod 233 drives the flange 251 on one side to the top of the support frame 23. As the hinge rod 233 continues to rotate, the hinge rod 233 drives the flange 251 to slide along the upper end surface of the support frame 23. As the hinge rod 233 is driven by the mounting plate 232 to descend, the flange 251 sliding along the upper end surface of the support frame 23 is blocked by the support frame 23 and the return spring 252 is stretched to slide along the moving groove 25 until the hydraulic support passes between the two hinge rods 233.

[0052] At this time, the transmission unit is controlled to operate so that the drive motor 17 can drive the cylinder 16 to rotate. Since the end of the steel wire 161 away from the cylinder 16 passes through the end of the hinged rod 233 away from the support frame 23 and is connected to the clamping plate 22, during the process of the cylinder 16 winding around the steel wire 161, the steel wire 161 pulls the clamping plate 22 to the end of the slide groove 21 away from the support frame 23. At this time, the clamping plate 22 cannot slide. At this time, the steel wire 161 pulls the upwardly tilted hinged rod 233 through the clamping plate 22 to continue rotating until the hinged rod 233 rotates to a vertical state.

[0053] Since the mounting plate 232 and the screw rod 234 are in a spiral transmission and non-self-locking structure, the mounting plate 232 will slide downward along the screw rod 234 under the action of gravity, and the flange 251 will slide to one end of the moving groove 25. At this time, the hinged rod 233 pulled by the wire rope 161 slides along the upper end of the support frame 23 through the flange 251 until the hinged rod 233 rotates to a vertical state. At this time, the flange 251 enters the mounting groove 231, so that the hinged rod 233 falls to the bottom of the mounting groove 231 under the action of its own gravity.

[0054] The present invention sets up the cooperation between the mounting frame 2 and the clamping assembly so that when the hinged rod 233 of the mounting frame 2 is extended, it can drive the iron chain clamped by the clamping assembly to be transferred to the clamping assembly directly opposite to it, so that in the process of the two clamping assemblies transferring the iron chain, the iron chain can pass over the hydraulic support on the support plate 11, thereby eliminating the need for workers to repeatedly disassemble and install the steel cable connecting the crane and the hydraulic support. On the one hand, this reduces the labor intensity of the workers; on the other hand, it reduces the overall disassembly time of the hydraulic support and improves the disassembly efficiency; thus, the practicality of the present invention is effectively improved.

[0055] As an embodiment of the present invention, a rectangular groove 243 is provided at one end of the bevel gear shaft 242 away from the bevel gear ring 241; a slot 171 is provided inside the body 1; a connecting rod 172 that cooperates with the rectangular groove 243 is slidably connected in the slot 171; a groove 173 is provided on the output shaft of the drive motor 17; and the connecting rod 172 is slidably and sealedly connected in the groove 173.

[0056] The transmission unit includes a worm wheel 174 and a worm 175; the worm wheel 174 is meshed with the worm 175; the worm wheel 174 is fixedly connected to the cylinder 16; the worm 175 is transmission-connected to the output shaft of the driving motor 17 via a bevel gear 176 group; the bevel gear 176 group includes two bevel gears 176 meshing with each other; one of the bevel gears 176 is fixedly connected to the worm 175; the other bevel gear 176 is fixedly connected to the surface of the connecting rod 172; the connecting rod 172 is fixedly connected to the bottom of the groove 173 via a connecting spring 177; an electromagnetic block 178 is embedded in the groove 173.

[0057] In the initial state, the electromagnetic block 178 is in a power-off state. At this time, the connecting rod 172 extends out of the groove 173 and inserts into the rectangular groove 243 under the push of the restoring force of the connecting spring 177.
