Description

Technical Field

[0001] This utility model belongs to the technical field of mining auxiliary equipment, and in particular relates to a roof cut-hole support and fixing device. Background Technology

[0002] According to the published patent CN222501769U, a support device for a fractured roof in an underground mine includes a connecting device comprising a connecting plate bolted to the inner wall of a fixing groove. A connecting plate is fixedly mounted at one end of the connecting plate, and connecting holes are formed on both sides of the connecting plate. These connecting holes are adapted to connect with a fixing rod. A connecting rod is fixedly mounted at the other end of the connecting plate. A placement groove is formed above the connecting plate, and a connecting groove is formed at one end of the connecting plate. Subsequently, as needed, the connecting plate at one end of the connecting plate is inserted into the fixing groove, and the fixing rod is inserted into the connecting hole. The connecting plate and the fixing groove are then fixed with bolts. Further connecting devices can be added as needed, such that the connecting plate at one end of the connecting plate is inserted into the connecting groove, and the connecting rod is inserted into the connecting hole. This increases the number of connecting devices and the width of the device, allowing it to adapt to a wider range of mine widths. However, the following shortcomings still exist:

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates an electric push rod and a protective plate. The extension of the electric push rod moves the second positioning seat, simultaneously causing the protective plate to rotate around the outside of the connecting block. The rotation of the protective plate pulls the electric push rod to rotate around the first positioning seat. This extension of the electric push rod causes the protective plate to rotate outwards, increasing the device's coverage area. The extension of the electric push rod also drives the protective plate to rotate around the connecting block, preventing blind spots caused by deviations in the angles of the protective plates on both sides, which are difficult to control precisely when manually adjusting the angle of the protective plate due to the complex internal environment of the mine and the need to change the angle of the roof at different locations.

[0017] 2. This utility model incorporates a second damper and a second spring. The movement of the positioning shaft pushes the first positioning rod to rotate around the second positioning block. The rotation of the first positioning rod then drives the positioning shaft, causing the limiting block to move inside the slide groove. This allows the first positioning rod to share the pressure on the support rod. Simultaneously, the movement of the limiting block compresses the second damper and the second spring inside the slide groove. The interaction between the second damper and the second spring alleviates and absorbs the pressure generated when the limiting block moves. The rotation of the first positioning rod pushes the slider to compress the second damper and the second spring. The interaction between the second damper and the second spring also alleviates the pressure generated when the slider moves and absorbs the pressure on the outside of the rubber sleeve. This prevents the potential for broken rocks in the mine, vibrations from machine operation, and personnel movement from causing rocks to fall and directly hit the top of the device, resulting in dents and damage to the device's surface and reducing its service life.

[0018] 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

[0027] 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.

[0028] Please see Figure 1-5 As shown, this utility model is a top plate cut-hole support and fixing device, including a support frame 1, and a connecting plate 101 is fixedly connected to the top outer wall of the support frame 1;

[0029] An extension mechanism 2 is provided on the outer wall of the support frame 1. The extension mechanism 2 includes a connecting block 201. The outer wall of the connecting block 201 is fixedly connected to the outer wall of the support frame 1. A protective plate 202 is rotatably connected to the outer wall of the connecting block 201. The connecting block 201 restricts the outer side of the support frame 1 by using the protective plate 202. A first positioning seat 203 is fixedly connected to the top of the inner wall of the support frame 1. An electric push rod 204 is rotatably connected to the inner wall of the first positioning seat 203. When the electric push rod 204 is activated, the extension of the electric push rod 204 pushes the second positioning seat 205, causing the protective plate 202 to rotate around the outer side of the connecting block 201. At the same time, the electric push rod 204 rotates around the first positioning seat 203, thereby allowing the protective plate 202 to rotate outward and open. The outer wall of the push rod 204, away from the first positioning seat 203, is rotatably connected to the second positioning seat 205. A connecting seat 206 is fixedly connected to the top of the inner wall of the connecting plate 101. A first connecting rod 207 is rotatably connected to the inner wall of the connecting seat 206. A second connecting rod 208 is rotatably connected to the outer wall of the first connecting rod 207, away from the connecting seat 206. A first slider 209 is rotatably connected to the outer wall of the second connecting rod 208. When the protective plate 202 rotates, it pulls the first slider 209, causing it to move the second connecting rod 208 while simultaneously pulling the first connecting rod 207 to rotate around the interior of the connecting seat 206. Thus, the cooperation between the first connecting rod 207 and the second connecting rod 208 supports the rotation of the protective plate 202 and increases its stability. To enhance the protective strength, a first damper 210 is fixedly connected to the outer wall of the first slider 209, and a shock-absorbing mechanism 3 is provided on the outer wall of the connecting plate 101. A first spring 211 is fixedly connected to the outer wall of the first damper 210. When the second connecting rod 208 rotates, it pushes the first slider 209 to move outward and pulls the first damper 210 and the first spring 211. Through the cooperation of the first damper 210 and the first spring 211, the pressure generated when the first slider 209 moves can be relieved and absorbed, and the pressure and vibration of the protective plate 202 can be absorbed. A telescopic rod 212 is rotatably connected to the outer wall of the second connecting rod 208. A second slider 213 is rotatably connected to the outer wall of the end of the telescopic rod 212 away from the second connecting rod 208. 8 drives the first connecting rod 207 to rotate, while simultaneously driving the telescopic rod 212 to rotate around the second slider 213. The telescopic rod 212 pulls the second slider 213 to move along the interior of the protective plate 202. The extension of the telescopic rod 212 supports the rotation of the second connecting rod 208 and the first connecting rod 207 and limits their range of movement. The outer wall of the second positioning seat 205 is fixedly connected to the outer wall of the protective plate 202. The outer wall of the first slider 209 is slidably connected to the outer wall of the protective plate 202. The outer wall of the first damper 210 is fixedly connected to the outer wall of the protective plate 202. The outer wall of the first spring 211 is fixedly connected to the outer wall of the first slider 209. The outer wall of the second slider 213 is slidably connected to the outer wall of the protective plate 202.

[0030] The shock absorption mechanism 3 includes a rubber sleeve 301. The outer wall of the rubber sleeve 301 is fixedly connected to the outer wall of the connecting plate 101. Several fixed seats 302 are fixedly connected to the top of the inner wall of the rubber sleeve 301. A support rod 303 is rotatably connected to the inner wall of the fixed seat 302. A first positioning block 304 is rotatably connected to the outer wall of the end of the support rod 303 away from the fixed seat 302. When the rubber sleeve 301 comes into contact with the inside of the mine, the rubber sleeve 301 will deform. The deformation of the rubber sleeve 301 pushes the multiple fixed seats 302 to move, and at the same time pushes the support rod 303 to rotate around the first positioning block 304. The rotation of the support rod 303 pushes the fixed seats 302 to cause them to extend the two sides of the rubber sleeve 301 outward, thereby wrapping around the inner wall of the mine and changing the support angle of the rubber sleeve 301 on the inner wall of the mine. To increase the pressure that can be withstood, the outer wall of the first positioning block 304 is fixedly connected to the outer wall of the connecting plate 101. The inner wall of the support rod 303 is provided with a sliding groove 305. The inner wall of the sliding groove 305 is slidably connected to a limit block 306. The outer wall of the limit block 306 is fixedly connected to a second damper 307. The outer wall of the second damper 307 is fixedly connected to the inner wall of the support rod 303. The outer wall of the second damper 307 is fixedly connected to a second spring 308. During the rotation of the support rod 303, the limit block 306 will be pushed to move along the inside of the sliding groove 305, while the second damper 307 and the second spring 308 will be squeezed. Thus, the cooperation between the second damper 307 and the second spring 308 will relieve and absorb the pressure on the support rod 303 during rotation and reduce the vibration generated during machine operation.

[0031] The outer wall of the second spring 308 is fixedly connected to the outer wall of the limiting block 306. Several positioning shafts 309 are fixedly connected to the outer wall of the limiting block 306. A first positioning rod 310 is rotatably connected to the outer wall of the positioning shafts 309. A second positioning block 311 is rotatably connected to the outer wall of the end of the first positioning rod 310 away from the positioning shafts 309. The movement of the limiting block 306 pushes the first positioning rod 310 to rotate around the second positioning block 311, while simultaneously pushing the positioning shafts 309 to move the first positioning rod 310 within the slide groove 305. This allows the first positioning rod 310 to share the pressure on the support rod 303. The outer wall of the second positioning block 311 is connected to... The outer wall of the connecting plate 101 is fixedly connected, and the outer wall of the limiting block 306 is rotatably connected to the second positioning rod 312. The outer wall of the second positioning rod 312 away from the limiting block 306 is rotatably connected to the third positioning block 313. During the movement of the limiting block 306, the second positioning rod 312 will be pushed to rotate around the third positioning block 313, while assisting in pushing the limiting block 306 to move inside the slide groove 305. Since the third positioning block 313 is located in the center of the rubber sleeve 301, the connection of the second positioning rod 312 can increase the support strength of the middle part of the rubber sleeve 301. The outer wall of the third positioning block 313 is fixedly connected to the inner wall of the rubber sleeve 301.

[0032] One specific application of this embodiment is:

[0033] When workers need to use the equipment, after the device is installed, the connecting plate 101 is raised close to the inner wall of the mine using the support frame 1, and the rubber sleeve 301 on top of the connecting plate 101 is brought into contact with the inside of the mine. The pressure inside the mine will squeeze the rubber sleeve 301, causing it to deform. The deformation of the rubber sleeve 301 will push the four fixed seats 302 inside to move to both sides simultaneously, while driving the support rod 303 to rotate around the first positioning block 304. The rotation of the support rod 303 will push the fixed seats 302 to push the sides of the rubber sleeve 301 outward, making the rubber sleeve 301 concave in shape. This allows the rubber sleeve 301 to completely support the inner wall of the mine and distribute the pressure on the rubber sleeve 301, avoiding localized pressure. Excessive size causes the already fragmented rock to further break up. During the rotation of the support rod 303, the limiting block 306 moves, simultaneously moving the positioning shaft 309. The movement of the positioning shaft 309 pushes the first positioning rod 310 to rotate around the second positioning block 311. The rotation of the first positioning rod 310 also drives the positioning shaft 309, causing the limiting block 306 to move inside the slide groove 305. This allows the first positioning rod 310 to share the pressure on the support rod 303. At the same time, the movement of the limiting block 306 compresses the second damper 307 and the second spring 308 inside the slide groove 305. The interaction between the second damper 307 and the second spring 308 can alleviate and absorb the movement of the limiting block 306. The pressure generated during the movement of the limiting block 306 will drive the second positioning rod 312 to rotate around the outside of the limiting block 306, while stabilizing the movement of the third positioning block 313. Since the third positioning block 313 is located in the center of the rubber sleeve 301, the connection of the second positioning rod 312 increases the support of the third positioning block 313 and the center of the rubber sleeve 301 for the broken rock, preventing damage to the center of the rubber sleeve 301 due to excessive pressure. Then, the electric push rod 204 fixed on the outside of the support frame 1 is activated. The extension of the electric push rod 204 pushes the second positioning seat 205 to move, while driving the protective plate 202 to rotate around the outside of the connecting block 201, and through the protective plate 202... Rotating the electric push rod 204 causes it to rotate around the interior of the first positioning seat 203. This extension of the electric push rod 204 causes the protective plate 202 to rotate outwards, increasing the coverage area of ​​the device. During the rotation of the protective plate 202, the first slider 209 moves. This movement of the first slider 209 pulls the second connecting rod 208, causing it to rotate around the interior of the first slider 209. The rotation of the second connecting rod 208 then causes the first connecting rod 207 to rotate around the interior of the connecting seat 206. The rotation of the first connecting rod 207 and the second connecting rod 208 pushes the first slider 209 to move along the outer side of the protective plate 202, with the first slider 209 moving away from the connecting block 201.When the first slider 209 moves to the outermost edge of the protective plate 202, the protective plate 202 stops rotating. The connection between the first link 207 and the second link 208 supports the outermost edge of the protective plate 202, preventing it from shaking or even being damaged due to excessive pressure when broken rock fragments fall onto its surface, thus ensuring its protective effect. During the movement of the first slider 209, it pulls on the first damper 210 and the first spring 211 connected to the outer edge of the protective plate 202. The interaction between the first damper 210 and the first spring 211 alleviates the pressure on the first slider 209 during movement and absorbs and relieves the pressure on the protective plate. The pressure and vibration experienced by the protective plate 202 increase its protective strength. When the second connecting rod 208 pulls the first connecting rod 207 to rotate, it drives the telescopic rod 212 to move. The telescopic rod 212 then pulls the second slider 213, causing it to move along the protective plate 202. Simultaneously, the rotation of the second connecting rod 208 shortens the telescopic rod 212, thus limiting the rotation range between the second connecting rod 208 and the first connecting rod 207. The connection of the telescopic rod 212 forms two triangles, increasing the stability of the protective plate 202 after deployment and preventing accidental shaking. The protective plate 202 on the other side of the device deploys in the same manner.
