Description

Technical Field

[0001] This utility model belongs to the technical field of mining auxiliary equipment, and in particular relates to a hydraulic support adjustment device. Background Technology

[0002] With the rapid development of my country's coal industry, intelligent coal mining is of paramount importance for achieving efficient development. The core of intelligent coal mining is to realize intelligent mining and intelligent services centered on mining. Among these, intelligent mining plays a leading role in the construction of intelligent coal mines, and the development of intelligent mining control technology and equipment plays a crucial role in the progress of intelligent coal mine development.

[0003] Activating the hydraulic rods allows them to extend automatically, pushing the support plate upwards. After extending to a certain height, the support plate contacts the inner wall of the mine. At this point, the pressure generated by the mine completely covers the surface of the support plate and is transmitted to the two hydraulic rods at the bottom. The upward thrust generated by the hydraulic rods supports the inner wall of the mine, preventing it from collapsing.

[0004] After the existing equipment is completed, the support plate directly bears the pressure of the inner wall of the mine. If the pressure is concentrated at a certain point, it is easy to exceed the compressive strength limit of the support plate, causing the support plate to deform. It may even transmit the pressure to the hydraulic rod, which may cause excessive local stress in the hydraulic rod cylinder and lose the support effect. Therefore, we propose a hydraulic support adjustment device. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic support adjustment device. Through the load-bearing mechanism and the shock absorption mechanism, it solves the problem that since the support plate directly bears the pressure of the inner wall of the mine, if the pressure is concentrated at a certain point, it is easy to exceed the compressive strength limit of the support plate, causing the support plate to deform. It may even transmit the pressure to the hydraulic rod part, which may cause excessive local stress in the hydraulic rod cylinder and lose the support effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a hydraulic support adjustment device, including a hydraulic rod, and a movable base is fixedly connected to the bottom outer wall of the hydraulic rod;

[0008] The outer wall of the hydraulic rod is provided with a load-bearing mechanism, which includes a connecting plate. The outer wall of the connecting plate is fixedly connected to the outer wall of the hydraulic rod. Several fixed seats are fixedly connected to the top outer wall of the connecting plate. A telescopic rod is rotatably connected to the inner wall of the fixed seat. A first slider is rotatably connected to the outer wall of the telescopic rod away from the fixed seat. A first damper is fixedly connected to the outer wall of the first slider. A first spring is fixedly connected to the outer wall of the first damper. A fixed block is fixedly connected to the outer wall of the first damper away from the first slider. A first connecting rod is rotatably connected to the inner wall of the fixed block. A second slider is rotatably connected to the outer wall of the first connecting rod away from the fixed block. A first support rod is rotatably connected to the outer wall of the first connecting rod. The outer wall of the hydraulic rod is provided with a shock-absorbing mechanism.

[0009] Furthermore, the outer wall of the first spring is fixedly connected to the outer wall of the first slider, the outer wall of the second slider is slidably connected to the outer wall of the connecting plate, and the outer wall of the first support rod is rotatably connected to the outer wall of the first slider.

[0010] Furthermore, the damping mechanism includes a fixed plate, the outer wall of which is fixedly connected to the outer wall of the hydraulic rod, a rubber sleeve is fixedly connected to the top outer wall of the fixed plate, a plurality of side support plates are fixedly connected to the top inner wall of the rubber sleeve, a support plate is fixedly connected to the top inner wall of the rubber sleeve, and a plurality of second dampers are fixedly connected to the bottom outer wall of the support plate, the outer walls of the second dampers being fixedly connected to the outer wall of the fixed plate.

[0011] Furthermore, a second spring is fixedly connected to the outer wall of the second damper, and the outer wall of the second spring is fixedly connected to the outer wall of the support plate. A connecting seat is fixedly connected to the bottom outer wall of the side support plate.

[0012] Furthermore, a second support rod is rotatably connected to the inner wall of the connecting seat, and a second connecting block is rotatably connected to the outer wall of the end of the second support rod away from the connecting seat. The outer wall of the second connecting block is fixedly connected to the outer wall of the fixing plate.

[0013] Furthermore, the inner wall of the second support rod is provided with a sliding groove, the inner wall of the sliding groove is slidably connected to a limit block, the outer wall of the limit block is rotatably connected to a positioning rod, and the outer wall of the positioning rod away from the limit block is rotatably connected to a first connecting block.

[0014] Furthermore, the outer wall of the first connecting block is fixedly connected to the outer wall of the fixing plate, and the inner wall of the limiting block is slidably connected to a sliding rod, the outer wall of the sliding rod being fixedly connected to the inner wall of the sliding groove.

[0015] Furthermore, a damping spring is fixedly connected to the outer wall of the slide rod, and the outer wall of the damping spring is fixedly connected to the outer wall of the limiting block. A third support rod is rotatably connected to the inner wall of the second connecting block, and the outer wall of the third support rod is rotatably connected to the inner wall of the side support plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a first damper and a first spring. The movement of the first slider pushes the telescopic rod to rotate around the interior of the fixed seat, simultaneously shortening the overall length of the telescopic rod. During the movement of the first slider, the first damper and the first spring are pulled. The cooperation between the first damper and the first spring can alleviate the pressure when the first slider moves. The cooperation between the first damper and the first spring absorbs and distributes the pressure on the support plate, preventing the support plate from directly bearing the pressure of the mine wall. If the pressure is concentrated at a certain point, it may easily exceed the compressive strength limit of the support plate, causing deformation of the support plate. In some cases, the pressure may even be transmitted to the hydraulic rod, potentially causing excessive local stress in the hydraulic rod cylinder and loss of support effect.

[0018] 2. This utility model incorporates a support plate and a second damper. The continuous movement of the fixed plate causes deformation of the rubber sleeve, which in turn moves the internal support plate downwards. The support plate then compresses the second damper and second spring at the bottom. The interaction between the second damper and second spring alleviates and absorbs the pressure on the support plate. Since the support plate is the first to contact the mine wall, it transmits the pressure to the second damper and second spring at the bottom, thus relieving the pressure on the support plate and preventing direct pressure from acting on the fixed plate at the bottom. This prevents the instantaneous rigid impact on the support plate caused by vibrations from the coal mining machine or falling rocks from the mine wall during coal mining. Such impacts typically generate significant pressure, easily leading to deformation of the hydraulic cylinder and reducing the lifespan of the device.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a hydraulic support adjustment device, including a hydraulic rod 1. A movable base 101 is fixedly connected to the bottom outer wall of the hydraulic rod 1. Since the movable base 101 has its own rollers, the device can be pushed relatively easily.

[0030] A load-bearing mechanism 2 is provided on the outer wall of the hydraulic rod 1. The load-bearing mechanism 2 includes a connecting plate 201. The outer wall of the connecting plate 201 is fixedly connected to the outer wall of the hydraulic rod 1. Since the connecting plate 201 is fixed to the outer shell of the hydraulic rod 1 and not fixedly connected to the piston part of the hydraulic rod 1, the connecting plate 201 will not move when the hydraulic rod 1 extends. Several fixed seats 202 are fixedly connected to the top outer wall of the connecting plate 201. A telescopic rod 203 is rotatably connected to the inner wall of the fixed seat 202. A first slider 204 is rotatably connected to the outer wall of the end of the telescopic rod 203 away from the fixed seat 202. When the fixed plate 301 moves downward due to pressure, the first slider 204... The first slider 204 is pushed and squeezed by the fixed plate 301, causing it to compress and rotate around the inside of the fixed base 202. The telescopic rod 203 pulls the first slider 204 to move at the bottom of the fixed plate 301. A first damper 205 is fixedly connected to the outer wall of the first slider 204, and a first spring 206 is fixedly connected to the outer wall of the first damper 205. During the movement of the first slider 204, the first spring 206 and the first damper 205 are pulled. Through the cooperation of the first damper 205 and the first spring 206, the pressure generated when the first slider 204 moves is relieved and absorbed, and the pressure on the first slider 204 is shared. 04 is subjected to pressure from the fixed plate 301. A fixed block 207 is fixedly connected to the outer wall of the first damper 205 away from the first slider 204. A first connecting rod 208 is rotatably connected to the inner wall of the fixed block 207. A second slider 209 is rotatably connected to the outer wall of the first connecting rod 208 away from the fixed block 207. Since the fixed block 207 is directly below the fixed plate 301, it moves along with the fixed plate 301, thus pushing the first connecting rod 208 to rotate around the fixed block 207 while simultaneously pushing the second slider 209 to move on the surface of the connecting plate 201. The outer wall of rod 208 is rotatably connected to a first support rod 210. Since the two ends of the first support rod 210 are connected to the first connecting rod 208 and the first slider 204 respectively, the first support rod 210 can limit the movement range of the first slider 204 and the rotation angle of the first connecting rod 208, and at the same time share the pressure on the first connecting rod 208. The outer wall of the hydraulic rod 1 is provided with a shock absorption mechanism 3. The outer wall of the first spring 206 is fixedly connected to the outer wall of the first slider 204. The outer wall of the second slider 209 is slidably connected to the outer wall of the connecting plate 201. The outer wall of the first support rod 210 is rotatably connected to the outer wall of the first slider 204.

[0031] The shock absorption mechanism 3 includes a fixed plate 301. The outer wall of the fixed plate 301 is fixedly connected to the outer wall of the hydraulic rod 1. Since the fixed plate 301 is fixed to the top of the hydraulic rod 1, the fixed plate 301 will be pushed upward when the hydraulic rod 1 extends. A rubber sleeve 302 is fixedly connected to the top outer wall of the fixed plate 301. The rubber sleeve 302 completely wraps the surface structure of the fixed plate 301 to prevent leakage and increase the possibility of structural corrosion caused by gas in the mine. Several side support plates 303 are fixedly connected to the top of the inner wall of the rubber sleeve 302. A support plate 304 is fixedly connected to the top of the inner wall of the rubber sleeve 302. The bottom outer wall of the support plate 304 is fixedly connected to... Several second dampers 305 are connected. The outer wall of the second damper 305 is fixedly connected to the outer wall of the fixed plate 301. A second spring 306 is fixedly connected to the outer wall of the second damper 305. The outer wall of the second spring 306 is fixedly connected to the outer wall of the support plate 304. When the rubber sleeve 302 contacts the inner wall of the mine, the pressure generated by the extension of the hydraulic rod 1 will squeeze the second damper 305 and the second spring 306 at the bottom of the support plate 304. Through the cooperation of the second damper 305 and the second spring 306, the pressure on the support plate 304 can be relieved and absorbed. A connecting seat 307 is fixedly connected to the bottom outer wall of the side support plate 303.

[0032] A second support rod 308 is rotatably connected to the inner wall of the connecting seat 307. A second connecting block 315 is rotatably connected to the outer wall of the end of the second support rod 308 away from the connecting seat 307. When the side support plate 303 is under pressure, it pushes the second support rod 308 to rotate around the second connecting block 315, while simultaneously pushing the connecting seat 307 to move to both sides. At the same time, the side support plate 303 rotates at a certain angle, thereby changing the shape of the rubber sleeve 302 so that the rubber sleeve 302 can wrap around the mine shaft. The outer wall of the second connecting block 315 is fixedly connected to the outer wall of the fixing plate 301. The inner wall of the second support rod 308... A groove 309 is provided in the wall. A limit block 310 is slidably connected to the inner wall of the groove 309. A positioning rod 313 is rotatably connected to the outer wall of the limit block 310. A first connecting block 314 is rotatably connected to the outer wall of the end of the positioning rod 313 away from the limit block 310. The rotation of the second support rod 308 will drive the limit block 310 inside the groove 309 to move, while pushing the positioning rod 313 to rotate around the first connecting block 314. Thus, the positioning rod 313 supports the rotation of the second support rod 308 and shares the pressure on the second support rod 308 when it rotates. The outer wall of the first connecting block 314 is connected to the... The outer wall of the fixed plate 301 is fixedly connected, and the inner wall of the limiting block 310 is slidably connected to a slide rod 311. The outer wall of the slide rod 311 is fixedly connected to the inner wall of the slide groove 309. A damping spring 312 is fixedly connected to the outer wall of the slide rod 311. When the positioning rod 313 rotates, it pushes the limiting block 310 to move along the inside of the slide groove 309. At the same time, the slide rod 311 limits the movement range of the limiting block 310 and allows the limiting block 310 to compress the damping spring 312 on the outside of the slide rod 311. Thus, the elasticity of the damping spring 312 relieves the pressure on the limiting block 310. The outer wall of the damping spring 312 is fixedly connected to the inner wall of the limiting block 309. The outer wall of the 10 is fixedly connected, and the inner wall of the second connecting block 315 is rotatably connected to the third support rod 316. The outer wall of the third support rod 316 is rotatably connected to the inner wall of the side support plate 303. When the side support plate 303 moves, it will drive the third support rod 316 to rotate around the interior of the second connecting block 315. This allows the third support rod 316 to share the pressure on the side support plate 303 and limit the range of movement of the side support plate 303. It also allows the side support plate 303 to rotate around the third support rod 316, thereby changing the support angle of the side support plate 303 on the mine roof and supporting it.

[0033] One specific application of this embodiment is:

[0034] When workers need to use the equipment, the movable base 101 at the bottom of the hydraulic rod 1 facilitates the worker's pushing of the device. When the device moves to the designated position, the hydraulic rod 1 is activated to automatically extend it, pushing the fixed plate 301 upwards and simultaneously causing the rubber sleeve 302 to contact the top of the mine. The continuous movement of the fixed plate 301 causes the rubber sleeve 302 to deform, which in turn causes the internal support plate 304 to move downwards. The support plate 304 then compresses the second damper 305 and the second spring 306 at the bottom. The interaction between the second damper 305 and the second spring 306 relieves and absorbs the pressure on the support plate 304. Furthermore, the deformation of the rubber sleeve 302 causes the two... The side support plate 303 pushes the connecting seat 307 to move. The movement of the connecting seat 307 pushes the second support rod 308 to rotate around the interior of the second connecting block 315, thus supporting the movement of the side support plate 303. When the side support plate 303 moves, it pushes the third support rod 316 to rotate around the interior of the second connecting block 315. The two third support rods 316 inside the rubber sleeve 302 intersect each other. Therefore, the pressure on the side support plate 303 can be transmitted to the other side of the fixing plate 301 through the third support rods 316, thereby ensuring that the pressure on the fixing plate 301 is balanced and preventing the fixing plate 301 from being damaged due to excessive pressure on one end. The damage to 01 will cause the limiting block 310 to move during the rotation of the second support rod 308, while simultaneously pushing the positioning rod 313 to rotate around the outer side of the first connecting block 314. The rotation of the positioning rod 313 will push the limiting block 310 to slide along the inside of the slide groove 309, while the slide rod 311 will limit the movement range of the limiting block 310. The movement of the limiting block 310 will also compress the damping spring 312 on the outer side of the slide rod 311. The elasticity of the damping spring 312 will alleviate and absorb the pressure on the limiting block 310, thereby increasing the pressure that the fixing plate 301 can withstand. The fixing plate 301 will then release the pressure downwards, thereby pushing the multiple first sliders 204 at the bottom. The slider 204 moves along the interior of the fixed plate 301. The movement of the first slider 204 pushes the telescopic rod 203 to rotate around the interior of the fixed base 202, simultaneously shortening the overall length of the telescopic rod 203. This stabilizes the movement of the first slider 204, preventing wobbling. During the movement of the first slider 204, the first damper 205 and the first spring 206 are pulled. The interaction between the first damper 205 and the first spring 206 alleviates the pressure on the first slider 204 during movement, thus distributing the pressure on the fixed plate 301 and preventing damage to the device. When the first slider 204 moves, it pulls the first support rod 210, causing it to rotate around the outer side of the first slider 204.The first connecting rod 208 is pulled to rotate around the interior of the fixed block 207. Since the fixed block 207 is also in contact with the bottom of the fixed plate 301, the fixed block 207 moves downward along with the fixed plate 301, actively pushing the first connecting rod 208 to rotate while simultaneously pushing the second slider 209 to move outside the connecting plate 201. Therefore, the first support rod 210 can also share the pressure borne by the first connecting rod 208 during the pulling process, thus ensuring that the fixed plate 301 will not break due to excessive pressure. Furthermore, since the connecting plate 201 is not connected to the piston part of the hydraulic rod 1, the connecting plate 201 will not move when the hydraulic rod 1 extends, while the mechanism connected to the surface of the connecting plate 201 will move in the opposite direction, thereby stabilizing the rise of the fixed plate 301.
