Description

Technical Field

[0001] This invention relates to the field of mine support technology, and in particular to a mine roadway support device. Background Technology

[0002] During the mining process, issues such as rock mass fracturing, unstable geological structure, and rock bursts can all have adverse effects on the stability of the mine, mine safety, and mine production.

[0003] Currently, permanent supports provide a fixed amount of support to the mine wall. When a minor collapse occurs in the mine wall, workers cannot detect it in advance and cannot reinforce the collapsed area in time. When a small-scale collapse occurs in the mine wall, the permanent supports cannot provide stronger support and cannot prevent accidents from happening. Summary of the Invention

[0004] In order to overcome the shortcomings of existing permanent supports that cannot provide effective support for the inner wall of the mine, the present invention provides a mine roadway support device.

The support mechanism includes two sets of sleeves hinged to the support frame. A sliding plate is slidably installed inside the sleeve. A first compression spring is disposed between the sliding plate and the sleeve. A movable rod that slides along the inner wall of the sleeve is rotatably installed on the sliding plate. A connecting block is movably sleeved at the bottom of the movable rod. A support foot is elastically hinged to the connecting block. A guide groove is opened inside the connecting block. An extrusion block that matches the guide groove is fixedly installed on the movable rod. A limiting component for limiting the position of the movable rod is disposed inside the sleeve.

[0006] Furthermore, the guide groove is spiral-shaped.

[0007] Furthermore, the limiting component includes an elliptical block fixedly sleeved on the movable rod, and the bottom of the sliding plate is symmetrically provided with a sliding groove. A locking tooth plate that cooperates with the elliptical block is elastically slidably installed in the sliding groove, and a pair of tooth grooves that match the locking tooth plate are provided in the sleeve.

[0008] Furthermore, the monitoring mechanism includes a portal frame that is slidably installed in the bracket. A row of first monitoring plates is provided on the upper side of the portal frame. Four sets of L-shaped limiting plates are fixedly installed at the bottom of the portal frame. The L-shaped limiting plates are slidably installed in the bracket in the vertical direction. A second compression spring is provided between the L-shaped limiting plates and the bracket. A locking rod that cooperates with the L-shaped limiting plates is fixedly sleeved on the outer wall of the movable rod.

[0009] Furthermore, the monitoring mechanism also includes a row of adjusting push plates that slide through the bracket in the front-back direction. A first telescopic rod is fixedly installed on the portal frame on one side of the adjusting push plate. The telescopic end of the first telescopic rod is fixedly installed on the first monitoring plate. A connecting shaft is fixedly installed through the telescopic end of the first telescopic rod. A vertical groove matching the connecting shaft is opened through the fixed end of the first telescopic rod. The connecting shaft passes through the vertical groove and is connected to the adjusting push plate through a pair of connecting rods.

[0010] Furthermore, a groove is provided on the telescopic end of the first telescopic rod, and a first elastic locking block is slidably installed in the groove. A slot matching the first elastic locking block is provided on the inner wall of the fixed end of the first telescopic rod.

[0011] Furthermore, it also includes multiple splicing plates disposed between the two brackets, with a row of second monitoring plates disposed on the upper side of the splicing plates, and a lead screw threadedly connected to the splicing plates fixedly installed at the bottom of the second monitoring plates.

Two sets of second telescopic rods are symmetrically fixedly installed in the bracket, with the push rod hinged to the telescopic end of the second telescopic rod, and a brush roller rotatably installed at the telescopic end of the second telescopic rod.

[0013] Furthermore, a spool is fixedly sleeved on the roller shaft of the brush roller, and a pull rope connected to the bracket is wound around the spool. A coil spring is provided between the spool and the telescopic end of the second telescopic rod.

[0014] Furthermore, it also includes a limiting rod disposed on the lower side of the slider and elastically slidably connected to the bracket, and a U-shaped rod that cooperates with the limiting rod is fixedly installed on the L-shaped limiting plate near the limiting rod. Beneficial effects

[0015] 1. This invention, through the design of the monitoring mechanism, can monitor whether a mine collapse has occurred. When a minor collapse occurs in the mine, the monitoring mechanism, in conjunction with the support mechanism, can provide further support to the support structure, enabling the support structure to provide more effective support to the mine. Through the design of the limiting component, the movable rod can be limited, realizing adaptive adjustment of the extension length of the movable rod and optimizing the support effect on the support structure.

[0016] 2. Through the design of the positioning rod, the height of the first monitoring plate can be adjusted by adjusting the push plate, so that the first monitoring plate can fit against the top of the mine. Through the design of the splicing plate, the top of the mine between the two support devices can be monitored, increasing the monitoring range of the monitoring mechanism. By observing the support mechanism, the staff can determine whether the top of the mine has collapsed and determine the extent of the collapse, so as to further reinforce the support of the mine at the collapse location.

Detailed Implementation

[0019] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Example

[0020] A type of mine roadway support equipment, such as Figure 1-12 As shown, the device includes a support frame 1, a monitoring mechanism and a support mechanism mounted on the support frame 1. The monitoring mechanism is used to detect the top of the mine shaft. The support mechanism includes two sets of sleeves 201 hinged to the support frame 1, each set consisting of two sleeves, one in front and one behind. A sliding plate 202 is slidably installed inside the sleeve 201. A first compression spring is provided between the top of the sliding plate 202 and the inner wall of the sleeve 201. A movable rod 203 that slides along the inner wall of the sleeve 201 is rotatably mounted on the bottom of the sliding plate 202. A connecting block 204 is movably sleeved on the bottom of the movable rod 203. A support foot 205 is elastically hinged on the connecting block 204. A guide groove 206 is provided inside the connecting block 204. The guide groove 206 is spiral in shape. A squeezing block 207 that matches the guide groove 206 is fixedly installed on the movable rod 203. When the squeezing block 207 slides along the guide groove 206, it can make the movable rod 203 rotate. A limiting component is provided inside the sleeve 201 to limit the position of the movable rod 203.

[0021] like Figure 4 As shown, the limiting component includes an elliptical block 301 fixedly sleeved on the movable rod 203. The bottom of the sliding plate 202 is symmetrically provided with a sliding groove. A locking tooth plate 302 that cooperates with the elliptical block 301 is elastically slidably installed in the sliding groove. When the elliptical block 301 rotates, the two locking tooth plates 302 can move away from each other. A pair of tooth grooves that match the locking tooth plates 302 are provided in the sleeve 201.

[0022] like Figures 5-7 As shown, the monitoring mechanism includes a portal frame 401 that is slidably installed in the support 1 along the vertical direction. Three first monitoring plates 402 are equidistantly distributed on the upper side of the portal frame 401. Four sets of L-shaped limiting plates 403 are fixedly installed at the bottom of the portal frame 401. Each set consists of two plates on the left and two on the right. The L-shaped limiting plates 403 are slidably installed in the support 1 along the vertical direction. A second compression spring is provided between the bottom of the L-shaped limiting plate 403 and the inner wall of the support 1. A locking rod 404 that cooperates with the L-shaped limiting plate 403 is fixedly sleeved on the outer wall of the movable rod 203.

[0023] like Figure 7 and Figure 8As shown, the monitoring mechanism also includes three equidistantly distributed adjusting push plates 501 that slide through the bracket 1 in the front-back direction. A first telescopic rod 502 is fixedly installed on the top of the portal frame 401 on the rear side of the adjusting push plate 501. The telescopic end of the first telescopic rod 502 is fixedly installed on the bottom of the first monitoring plate 402. A connecting shaft is fixedly installed through the telescopic end of the first telescopic rod 502. A vertical groove matching the connecting shaft is opened through the fixed end of the first telescopic rod 502. The connecting shaft passes through the vertical groove and is connected to the adjusting push plate 501 through a pair of connecting rods 503.

[0024] like Figure 8 As shown, a groove is provided at the bottom front side of the telescopic end of the first telescopic rod 502, and a first elastic block 601 is slidably installed in the groove along the horizontal direction. A slot matching the first elastic block 601 is provided on the inner wall of the fixed end of the first telescopic rod 502.

[0025] Initially, the L-shaped limiting plate 403 limits the locking rod 404, causing the locking rod 404 to limit the movable rod 203. The movable rod 203, through the sliding plate 202, keeps the first compression spring in a contracted state. The sleeve 201 is perpendicular to the movable rod 203. The support leg 205 is housed in the bracket 1. The extrusion block 207 is located at the top of the guide groove 206. The first compression spring is in a contracted state, and the telescopic end of the first telescopic rod 502 is in a contracted state. The top surfaces of the three first monitoring plates 402 are on the same horizontal plane. Due to the unevenness of the mine roof, during the installation of the support equipment, the three first monitoring plates 402 may not be in contact with the mine roof evenly, resulting in the inability of the three first monitoring plates 402 to accurately monitor the mine collapse. At this time, the workers... The operator pushes the adjusting push plate 501 backward. The adjusting push plate 501, through the connecting rod 503, applies a thrust to the connecting shaft at the telescopic end of the first telescopic rod 502. The force on the connecting shaft causes the telescopic end of the first telescopic rod 502 to extend. The telescopic end of the first telescopic rod 502 causes the first monitoring plate 402 and the first elastic locking block 601 to rise. Under the action of the locking groove at the fixed end of the first telescopic rod 502, the first elastic locking block 601 continuously contracts and releases its sliding motion until the first monitoring plate 402 contacts the top of the mine. The adjusting push plate 501 is then released, and the telescopic end of the first telescopic rod 502 stops moving. The first elastic locking block 601, through its engagement with the locking groove at the fixed end of the first telescopic rod 502, limits the telescopic end of the first telescopic rod 502, thereby causing the first monitoring plate 402 to begin moving. The system maintains contact with the mine top. When a slight collapse occurs at the mine top, the collapsed area presses against the first monitoring plate 402. The force on the first monitoring plate 402 causes the telescopic end of the first telescopic rod 502 to descend. The telescopic end of the first telescopic rod 502 then presses against the groove of the fixed end of the first telescopic rod 502 using the first elastic locking block 601. This causes the first telescopic rod 502 to slide downwards along the portal frame 401. The portal frame 401 then causes four sets of L-shaped limiting plates 403 to descend. After the L-shaped limiting plates 403 descend, they no longer contact the locking rod 404, allowing the movable rod 203 and sleeve 201 to move freely. When a slight collapse occurs on the inner wall of the mine, the monitoring mechanism no longer limits the movable rod 203, allowing the two adjacent sleeves to move freely. The cylinder 201 rapidly moves away from each other, elastically releasing and rotating to unfold in a figure-eight shape, driving the movable rod 203 to move. Simultaneously, the first compression spring releases, causing the sliding plate 202 to slide. The sliding plate 202 drives the movable rod 203 to extend out of the sleeve 201. The movable rod 203, through the connecting block 204, drives the support leg 205 to move. After moving, the support leg 205 no longer contacts the support 1 and elastically releases and rotates until it contacts the bottom of the mine. The support leg 205 provides support for the connecting block 204, which then stops moving. The sliding plate 202 continues to slide under the action of the first compression spring, driving the movable rod 203 to continue sliding. The bottom end of the movable rod 203 slides along the inner wall of the connecting block 204, driving the extrusion block 207 to slide along the guide groove 206.Under the action of the guide groove 206, the extrusion block 207 drives the movable rod 203 to rotate around the connection point of the sliding plate 202. The movable rod 203 drives the elliptical block 301 to rotate 90 degrees. When the elliptical block 301 rotates, it squeezes the two locking tooth plates 302, causing the two locking tooth plates 302 to slide away from each other elastically. After sliding, the locking tooth plates 302 engage with the tooth grooves of the sleeve 201. At this time, the sliding plate 202 provides further support for the support 1 through the cooperation of the locking tooth plates 302 and the tooth grooves, preventing the support 1 from tilting due to the collapse of the mine, and making the support 1 provide stronger support for the mine, preventing the collapse of the mine from becoming more serious.

[0026] It is worth noting that, since the bottom of the mine is not flat, the locking plate 302 can only engage with the toothed groove of the sleeve 201 when the support leg 205 is in contact with the bottom of the mine. This allows for adaptive adjustment of the extension length of the movable rod 203, optimizing the support effect on the support 1. Initially, the L-shaped limiting plate 403 limits the locking rod 404, causing the sleeve 201 and the movable rod 203 to retract into the support 1. This makes it easier for workers to move and install the support equipment, saving working time. When there is no collapse in the mine, the support 1 alone can provide support for the mine. Example

[0027] like Figure 9 and Figure 10 As shown, it also includes three splicing plates 701 disposed between the two brackets 1. Three second monitoring plates 702 are disposed on the upper side of the splicing plate 701. A lead screw 703 that is threadedly connected to the splicing plate 701 is fixedly installed at the bottom of the second monitoring plate 702. A pair of slots that match the splicing plate 701 are provided on the first monitoring plate 402. A pair of second elastic blocks 704 that cooperate with the splicing plate 701 are slidably installed in the slots along the horizontal direction.

[0028] Initially, the splicing plate 701 and the first monitoring plate 402 are separated. During the installation of the support equipment, the gap between each support device is pre-adjusted to match the length of the splicing plate 701. After the support equipment is installed, the front and rear ends of the splicing plate 701 are respectively inserted into the two slots of the first monitoring plate 402, which are positioned opposite each other. The splicing plate 701 presses against the inclined surface of the second elastic block 704. The second elastic block 704 elastically contracts and slides under pressure until the splicing plate 701 passes over the inclined surface of the second elastic block 704. The second elastic block 704 then releases its restraint, elastically releases, and slides back to its original position, providing support for the splicing plate 701. At this point, the splicing plate 701 can still move slightly within the slots of the first monitoring plate 402. When adjusting the angle, the splicing plate 701 will not affect the first monitoring plate 402, thus completing the assembly of the splicing plate 701. Then, the operator rotates the handwheel at the bottom of the screw 703 to make the top of each second monitoring plate 702 contact the top of the mine, thereby increasing the monitoring range of the monitoring mechanism. When a slight collapse occurs in the top of the mine between the two support devices, the second monitoring plate 702 is forced to lower the splicing plate 701. The splicing plate 701 lowers the first monitoring plate 402 through the second elastic locking block 704, thereby enabling the support mechanism to provide support for the support frame 1. By observing the support mechanism, the operator can determine whether a collapse has occurred in the top of the mine and determine the extent of the collapse, so as to further reinforce the support of the mine at the collapse location.

[0029] like Figure 11 and Figure 12 As shown, it also includes two sets of sliders 801 that are slidably installed in the bracket 1 in the vertical direction. Each set consists of two front and rear sliders. A tension spring is provided between the bottom of the slider 801 and the bracket 1. A push rod 802 is hinged to one side of the slider 801. Two sets of second telescopic rods 803 are symmetrically fixedly installed in the bracket 1. Each set consists of two front and rear telescopic rods. The push rod 802 is hinged to the telescopic end of the second telescopic rod 803. A brush roller 804 is rotatably installed on the telescopic end of the second telescopic rod 803.

[0030] like Figure 11 and Figure 12 As shown, a spool 901 is fixedly sleeved on the roller shaft of the brush roller 804. A pull rope connected to the bracket 1 is wound around the spool 901. A coil spring is provided between the spool 901 and the telescopic end of the second telescopic rod 803. When the telescopic end of the second telescopic rod 803 extends, the brush roller 804 can rotate to clean the bottom of the mine.

[0031] like Figure 11 and Figure 12As shown, it also includes a limiting rod 1001 disposed on the lower side of the slider 801 and elastically slidably connected to the bracket 1. The limiting rod 1001 is used to limit the slider 801. A U-shaped rod 1002 that cooperates with the limiting rod 1001 is fixedly installed on the side of the L-shaped limiting plate 403 near the limiting rod 1001.

[0032] Initially, the telescopic end of the second telescopic rod 803 is in a retracted state, the bottom of the slider 801 is in contact with the top of the limiting rod 1001, and the tension spring is in an extended state. When the L-shaped limiting plate 403 descends, the L-shaped limiting plate 403 drives the U-shaped rod 1002 to descend. The U-shaped rod 1002 squeezes the top of the limiting rod 1001, causing the limiting rod 1001 to elastically contract and slide. After the limiting rod 1001 slides, it no longer contacts the slider 801. The tension spring contracts and drives the slider 801 to slide downwards quickly. The slider 801 drives the telescopic end of the second telescopic rod 803 to extend through the push rod 802. The telescopic end of the second telescopic rod 803 drives the brush roller 804 to move. The pull rope on the spool 901 is released and drives the brush roller 804 to rotate. The brush roller 804 cleans the bottom of the mine to prevent coal particles from being present at the contact point between the support leg 205 and the bottom of the mine, which would prevent the support leg 205 from providing effective support for the support mechanism.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
