Description

Technical Field

[0001] This invention relates to the field of mineral mining equipment technology, specifically to a tunnel surrounding rock protection device. Background Technology

[0002] With the widespread adoption of coal mining, support devices for controlling the deformation of surrounding rock in roadways play a crucial role in coal mining. They enhance roadway stability, reduce the risk of rockfalls and collapses, ensure the safety of miners and equipment, lower maintenance costs, and simultaneously improve the efficiency and sustainability of coal mining.

[0003] In related technologies, the structural design of support devices for controlling the deformation of surrounding rock in roadways is unreasonable. These support devices lack the effect of reinforcing loosened surrounding rock in roadways, which can easily cause loose rocks at the top to fall and collapse, resulting in serious casualties and equipment damage, and reducing the safety of the support devices. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a roadway surrounding rock protection device, which provides good support for the roadway surrounding rock, effectively preventing the collapse of the roadway roof and the falling of rubble, and helping to ensure the safety of construction personnel and equipment.

[0006] The tunnel rock protection device according to an embodiment of the present invention includes: a mobile device comprising two mobile units movable along the length of the tunnel, the two mobile units being spaced apart along the width of the tunnel and defining a walking passage; a buffer device comprising a shielding member connected to the two mobile units respectively and covering the top of the walking passage; a height adjustment device comprising two height adjustment units respectively arranged on the two mobile units; and a support device comprising multiple support units spaced apart along the length of the tunnel, each support unit comprising a support frame and multiple anchors, the support frame protruding towards the tunnel roof and being elastic, the support frame spanning across the walking passage, and both ends of the support frame being connected to the two height adjustment units respectively, the height adjustment units being used to adjust the height of the support frame, and the multiple anchors being spaced apart along the length of the support frame and used to anchor the tunnel roof.

[0007] According to an embodiment of the present invention, the roadway rock protection device can be easily moved to a designated position to support the roadway roof rock because the moving unit is movable along the length of the roadway. Since the support frame protrudes towards the roadway roof and is elastic, and the height adjustment unit can drive the support frame to rise and fall, the height adjustment unit can move the support frame closer to the roadway roof when supporting roadways of different shapes and sizes. Because the roadway is elastic, it can adapt to the shape of the roadway roof and support the roadway roof through anchors. This improves the support effect of the roadway rock protection device, ensures the stability of the roadway, effectively prevents the collapse of the roadway roof and the falling of rubble, and helps ensure the safety of construction personnel and equipment.

[0008] In some embodiments, each height adjustment unit includes a plurality of telescopic columns, which are arranged on the moving unit along the length of the roadway, and the plurality of support units are connected to the plurality of telescopic columns in a one-to-one correspondence.

[0009] In some embodiments, the anchor includes a drill, an anchor bolt, a reinforcing cone, and a fastening component. The anchor bolt passes through the support frame. The drill is located at one end of the anchor bolt adjacent to the support frame and is used to drive the anchor bolt to rotate. The reinforcing cone is located on the side wall of the anchor bolt, and the fastening component is used to drive the reinforcing cone to extend out of the anchor bolt.

[0010] In some embodiments, the moving unit includes a first drive member, a track assembly, and a first cleaning assembly. The track assembly includes track strips. The first drive member is connected to the track strips to drive the track strips to rotate. The first cleaning assembly has a rejection plate and a first transmission member. The first transmission member is connected to the track strips and the rejection plate. The rejection plate is arranged adjacent to the outer wall surface of the track strips. The track strips can drive the rejection plate to move through the first transmission member to remove impurities on the outer wall of the track strips.

[0011] In some embodiments, the track strip is provided with a plurality of fixed teeth, which are arranged at intervals along the outer periphery of the track strip. The first transmission component further includes a gear disk and a transmission shaft arranged coaxially. The gear disk cooperates with the fixed teeth. The track assembly further includes a support frame. The transmission shaft extends along the width direction of the track strip and rotatably passes through the support frame. The gear disk and the rejection plate are both fixedly connected to the transmission shaft and arranged at intervals along the axial direction of the transmission shaft. When the track strip rotates, the fixed teeth can drive the gear disk to rotate, so that the transmission shaft drives the rejection plate to rotate.

[0012] In some embodiments, there are two track strips, which are respectively arranged on both sides of the support frame along the width direction of the tunnel; there are two rejection plates, which are arranged axially spaced along the drive shaft, and the two rejection plates correspond to the two track strips respectively; at least one gear disk is provided on one drive shaft; and / or, there are multiple first cleaning components, which are arranged spaced along the length direction of the track strips.

[0013] In some embodiments, the shielding member includes a buffer plate and a protective plate, the protective plate being connected to the buffer plate, the buffer plate being disposed directly above the walking channel, and the protective plate being disposed on one side of the buffer plate along the width direction of the buffer plate. The buffering device further includes a fixing frame and an elastic member, the lower end of the fixing frame being connected to the moving unit, the upper end of the fixing frame extending toward the buffer plate, and the elastic member being disposed between the fixing frame and the buffer plate, and the elastic member pressing the buffer plate toward the buffer plate.

[0014] In some embodiments, the buffer device further includes a connecting rod and an abutting rod. The connecting rod is eccentrically arranged on the gear disk, the upper end of the abutting rod is connected to the buffer plate, and the lower end of the abutting rod is located on the movement path of the connecting rod. The gear disk can drive the connecting rod to rotate eccentrically, thereby driving the abutting rod to move up and down reciprocally.

[0015] In some embodiments, the roadway surrounding rock protection equipment further includes a crushing device, which is located on the side of the moving unit away from the travel channel. The crushing device includes a second driving member and multiple sets of crushing rollers, which are arranged along the length of the moving unit. The second driving member is connected to the crushing rollers to drive the crushing rollers to rotate.

[0016] In some embodiments, the pulverizing device further includes a second cleaning component and a second transmission component. The second transmission component includes a first transmission member and a second transmission member. The second cleaning component includes a plurality of cleaning brushes, each of which corresponds to a plurality of sets of pulverizing rollers and abuts against the wall surface of the pulverizing rollers. The first transmission member is disposed on a connecting shaft between two adjacent sets of pulverizing rollers. The first transmission member cooperates with the second transmission member. The second transmission member is connected to the cleaning brushes. The connecting shaft can drive the first transmission member to rotate, thereby pushing the second transmission member to reciprocate along the axial direction of the pulverizing rollers, so that the second transmission member pushes the cleaning brushes to reciprocate along the axial direction of the pulverizing rollers.

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following is a reference appendix. Figures 1 to 9 A tunnel rock protection device according to an embodiment of the present invention is described.

[0034] like Figures 1 to 9 As shown, the roadway surrounding rock protection equipment according to an embodiment of the present invention includes: a moving device 1, a buffer device 2, a height adjusting device 3, and a support device 4. The moving device 1 includes two moving units 11, which are movable along the length direction of the roadway. The two moving units 11 are arranged at intervals along the width direction of the roadway, defining a walking passage 12. The buffer device 2 includes a shielding member 21, which is connected to the two moving units 11 respectively and covers the top of the walking passage 12. The height adjusting device 3 includes two height adjusting units 31, which are respectively arranged on the two moving units 11.

[0035] The support device 4 includes multiple support units 41, which are arranged at intervals along the length of the roadway. Each support unit 41 includes a support frame 411 and multiple anchors 412. The support frame 411 protrudes towards the roadway roof and is elastic. The support frame 411 spans across the passageway 12, and both ends of the support frame 411 are connected to two height adjustment units 31, which are used to adjust the height of the support frame 411. The multiple anchors 412 are arranged at intervals along the length of the support frame 411 and are used to anchor the roadway roof.

[0036] According to an embodiment of the present invention, the roadway rock protection device, since the moving unit 11 is movable along the length of the roadway, can be easily moved to a designated position to support the roadway roof rock. Because the support frame 411 protrudes towards the roadway roof and is elastic, and the height adjustment unit 31 can drive the support frame 411 to rise and fall, the height adjustment unit 31 can move the support frame 411 towards the roadway roof gradually when supporting roadways of different shapes and sizes. Since the roadway is elastic, it can adapt to the shape of the roadway roof and support the roadway roof through the anchors 412. This improves the support effect of the roadway rock protection device, ensures the stability of the roadway, effectively prevents the collapse of the roadway roof and the falling of rubble, and helps ensure the safety of construction personnel and equipment.

[0037] It should be noted that the walking passage 12 is accessible to construction personnel and equipment. The length of the passage is... Figure 1 The front-to-back direction of the tunnel, and the width direction of the tunnel are... Figure 1 Left and right directions.

[0038] In some embodiments, such as Figures 1 to 3 As shown, each height adjustment unit 31 includes multiple telescopic columns 311, which are arranged along the length of the roadway on the moving unit 11. Multiple support units 41 are connected to the multiple telescopic columns 311 in a one-to-one correspondence. It can be understood that multiple support units 41 can be individually controlled through different telescopic columns 311. This allows the support device 4 to support roadway roofs of different shapes and to quickly adapt to roadway deformation, effectively reducing the impact of rock pressure on the support device 4 and improving roadway stability. Furthermore, anchors 412 are drilled and anchored to the surrounding rock to resist rock deformation and displacement, reducing the risk of rock collapse and ensuring the safety of personnel and equipment within the roadway.

[0039] Specifically, such as Figure 4As shown, the anchor 412 includes a drill rig 4121, an anchor bolt 4122, a reinforcing cone 4123, and a fastening component 4124. The anchor bolt 4122 passes through the support frame 411. The drill rig 4121 is located at one end of the anchor bolt 4122 adjacent to the support frame 411 and is used to drive the anchor bolt 4122 to rotate. The reinforcing cone 4123 is located on the side wall of the anchor bolt 4122. The fastening component 4124 is used to drive the reinforcing cone 4123 to extend out of the anchor bolt 4122. Understandably, when the anchor 412 is in its initial position, the reinforcing cone 4123 is hidden inside the anchor rod 4122, thus not interfering with the anchor rod 4122 entering the anchor hole. After the anchor rod 4122 is inserted into the anchor hole, the reinforcing cone 4123 can be extended to the side wall of the anchor rod 4122 through the fastening component 4124. This can reinforce the rock surface, effectively resist the deformation and displacement of the rock strata, reduce the risk of rock collapse, and ensure the safety of personnel and equipment in the roadway.

[0040] For example, such as Figure 4 As shown, the fastening component 4124 includes a torsion wheel 41241 and a hexagonal pulley column 41242. The anchor rod 4122 is driven by the rotating rod of the drilling rig 4121, and the rotating rod of the drilling rig 4121 is fixedly installed at the bottom of the anchor rod 4122. The pulley column 41242 is rotatably installed on the surface of the rotating rod of the drilling rig 4121. The torsion wheel 41241 is fixedly installed at one end of the pulley column 41242 adjacent to the drilling rig 4121. The reinforcing cone 4123 is slidably installed in the slot of the anchor rod 4122 along the radial direction of the anchor rod 4122. The reinforcing cone 4123 is on the movement trajectory of the protruding part of the pulley column 41242. When the operator rotates the torsion wheel 41241, the torsion wheel 41241 drives the pulley column 41242 to rotate. The protrusion on the pulley column 41242 gradually abuts against the reinforcing cone 4123, thereby protruding and fixing the reinforcing cone 4123 outside the anchor bolt 4122. This avoids the risk of the anchor bolt 4122 coming out of the anchor hole and improves the stability of the roadway support.

[0041] Optionally, such as Figure 2 and Figure 3 As shown, the support frame 411 has multiple anchor frames 4111, each corresponding to a multiple anchor bolt 412. The anchor frames 4111 have through holes for inserting anchor bolts 4122. The support device 4 also includes an L-shaped block 413, which is mounted on the telescopic column 311. In other words, the support frame 411 is connected to the telescopic column 311 via the L-shaped block 413.

[0042] Furthermore, such as Figure 1 and Figure 3As shown, the height adjustment device 3 also includes a telescopic drive module 312. The telescopic drive module 312 is connected to the moving unit 11 through a connecting block 313. The telescopic drive module 312 is also connected to multiple telescopic columns 311 to control the extension and retraction of the telescopic columns 311. For example, the telescopic drive module 312 is a hydraulic pump and the telescopic column 311 is a hydraulic cylinder.

[0043] In some embodiments, such as Figure 6 and Figure 7 As shown, the moving unit 11 includes a first driving member 111, a track assembly 112, and a first cleaning assembly 113. The track assembly 112 includes track strips 1121. The first driving member 111 is connected to the track strips 1121 to drive the track strips 1121 to rotate. The first cleaning assembly 113 includes a removal plate 1131 and a first transmission component 1132. The first transmission component 1132 is connected to the track strips 1121 and the removal plate 1131. The removal plate 1131 is arranged adjacent to the outer wall surface of the track strips 1121. The track strips 1121 can drive the removal plate 1131 to move through the first transmission component 1132 to remove impurities on the outer wall of the track strips 1121. Understandably, the first driving component 111 drives the track 1121 to rotate, thereby driving the entire equipment to move forward and backward. When the track 1121 rotates, it can drive the first transmission component 1132 to move, and the first transmission component 1132 can drive the removal plate 1131 to move. Thus, the track 1121 and the first cleaning component 113 can share a single driving source, thereby reducing the production cost of the equipment. The structure is also compact and has good linkage.

[0044] Optionally, such as Figure 6 As shown, the track strip 1121 is provided with a plurality of fixed teeth 11211, which are arranged at intervals along the outer periphery of the track strip 1121. The first transmission component 1132 also includes a gear disk 11322 and a transmission shaft 11321 arranged coaxially. The gear disk 11322 cooperates with the fixed teeth 11211. The track assembly 112 also includes a support frame 1122. The transmission shaft 11321 extends along the width direction of the track strip 1121 and rotatably passes through the support frame 1122. The gear disk 11322 and the rejection plate 1131 are both fixedly connected to the transmission shaft 11321 and arranged at intervals along the axial direction of the transmission shaft 11321. When the track strip 1121 rotates, the fixed teeth 11211 can drive the gear disk 11322 to rotate, so that the transmission shaft 11321 drives the rejection plate 1131 to rotate. For example, the first driving element 111 is located inside the support frame 1122, and the first driving element 111 is either an electric motor or a hydraulic motor.

[0045] It is understandable that, such as Figure 6As shown, the gear disk 11322 is fixedly installed at the end of the drive shaft 11321 away from the support frame 1122. The gear disk 11322 is adjacent to the side wall of the track strip 1121 and is located on the movement trajectory of the fixed tooth 11211. The removal plate 1131 removes the mud, sand or gravel adhering to the track strip 1121 to the outside of the track strip 1121, thereby preventing the track strip 1121 from jamming during the machine's movement. This effectively reduces damage and wear to the track strip 1121, extends the life of the track strip 1121, improves the reliability and operating efficiency of the mechanical equipment, and reduces maintenance costs and downtime, thereby enhancing the performance and economic benefits of the equipment.

[0046] Optionally, such as Figure 6 As shown, there are two track strips 1121, which are arranged on both sides of the support frame 1122 along the width direction of the tunnel. There are also two removal plates 1131, which are arranged at intervals along the axial direction of the drive shaft, and each removal plate 1131 corresponds to one of the two track strips 1121. At least one gear disk 11322 is provided on one drive shaft 11321. It can be understood that each track strip 1121 corresponds to one removal plate 1131. The removal plate 1131 is installed above the corresponding track strip 1121. When the removal plate 1131 rotates, its tip can just contact the outer wall of the track strip 1121. When the gear disk 11322 drives the removal plate 1131 to rotate, the attached objects on the track strip 1121 can be removed to improve the stability of the equipment during movement.

[0047] Furthermore, such as Figure 6 As shown, there are multiple first cleaning components 113, which are arranged at intervals along the length of the track strip 1121, thereby further improving the cleaning effect of the track strip 1121.

[0048] In some embodiments, such as Figure 5 and Figure 8As shown, the shielding component 21 includes a buffer plate 211 and a protective plate 212. The protective plate 212 is connected to the buffer plate 211. The buffer plate 211 is located directly above the walking passage 12, and the protective plate 212 is located on one side of the buffer plate 211 along its width. The buffer device 2 also includes a fixing frame 24 and an elastic element 23. The lower end of the fixing frame 24 is connected to the moving unit 11, and the upper end of the fixing frame 24 extends towards the buffer plate 211. The elastic element 23 is located between the fixing frame 24 and the buffer plate 211, and it presses against the buffer plate 211. When gravel falls from the tunnel roof above the buffer plate 211, the buffer plate 211 can float up and down under the action of the elastic element 23 between the fixing frame 24 and the buffer plate 211, thereby reducing the impact of falling gravel, improving the safety of the working environment, and reducing the risk of potential injury and equipment damage.

[0049] For example, the elastic element 23 can be a spring, and there can be multiple elastic elements 23, which are arranged at intervals on the fixed frame 24. This can improve the cushioning effect of the buffer plate 211.

[0050] Furthermore, since the protective plate 212 is positioned along the width of the buffer plate 211 on one side of the buffer plate 211, it can prevent gravel from being guided to the edge of the roadway sidewall, thereby reducing the risk of gravel falling from above the passageway 12. In other words, the protective plate 212 can divert gravel to reduce the burden on the buffer plate 211, maintain its buffering effect, and at the same time reduce the difficulty and frequency of cleaning work, thereby improving roadway safety and operational efficiency.

[0051] Furthermore, such as Figure 8 As shown, the buffer device 2 also includes a connecting rod 25 and an abutting rod 26. The connecting rod 25 is eccentrically arranged on the gear disk 11322. The upper end of the abutting rod 26 is connected to the buffer plate 211, and the lower end of the abutting rod 26 is located on the movement path of the connecting rod 25. The gear disk 11322 can drive the connecting rod 25 to rotate eccentrically, thereby driving the abutting rod 26 to move up and down reciprocally. It can be understood that the gear disk 11322 can both drive the rejection plate 1131 to move and drive the buffer plate 211 to float up and down. In other words, the gear disk 11322 drives the connecting rod 25 to roll eccentrically. While rolling, the connecting rod 25 abuts against the lower end of the abutment rod 26, causing the abutment rod 26 to move up and down. The abutment rod 26 drives the buffer plate 211 to move up and down, and the buffer plate 211 drives the protective plate 212 to move up and down. The protective plate 212 shakes the gravel on the top to both sides, which can effectively loosen the adhering fallen stones and get rid of the buffer plate 211, reduce the burden on the buffer plate 211, maintain its buffering effect, and at the same time reduce the difficulty and frequency of cleaning work, and improve the safety and operating efficiency of the roadway.

[0052] In some embodiments, such as Figure 9 As shown, the roadway surrounding rock protection equipment also includes a crushing device 5, which is located on the side of the moving unit 11 away from the travel channel 12. The crushing device 5 includes a second driving member 51 and multiple sets of crushing rollers 52, which are arranged along the length of the moving unit 11. The second driving member 51 is connected to the crushing rollers 52 to drive the crushing rollers 52 to rotate. Specifically, the crushing device 5 also includes a bearing housing 56, through which the second driving member 51 is connected to the crushing rollers 52 to drive the crushing rollers 52 to rotate. When the protective plate 212 vibrates, it shakes the gravel to both sides. Due to the small gap between the inner wall of the tunnel and the crushing device 5, the gravel will roll to both sides of the crushing device 5. The second drive component 51 is activated, which drives the bearing in the drive bearing box 56 to rotate. The bearing in the drive bearing box 56 drives the crushing roller 52 to roll. The crushing roller 52 crushes and grinds the gravel, which can effectively reduce the accumulation and agglomeration of gravel, maintain the flatness and stability of the bottom of the support, reduce the impact of ground debris on equipment and personnel, and improve the safety and smoothness of tunnel passage.

[0053] For example, such as Figure 9 As shown, each set of crushing rollers 52 includes multiple roller bodies 521, which are arranged in the vertical direction. When the roller bodies 521 rotate, they can crush the gravel to reduce the accumulation and agglomeration of gravel.

[0054] Optionally, such as Figure 9 As shown, the crushing device 5 also includes a second cleaning component 54 and a second transmission component. The second transmission component includes a first transmission member 551 and a second transmission member 552. The second cleaning component 54 includes a plurality of cleaning brushes 541, which correspond one-to-one with a plurality of crushing rollers 52 and abut against the wall of the crushing rollers 52. The first transmission member 551 is disposed on the connecting shaft 53 between two adjacent sets of crushing rollers 52. The first transmission member 551 cooperates with the second transmission member 552. The second transmission member 552 is connected to the cleaning brushes 541. The connecting shaft 53 can drive the first transmission member 551 to rotate, thereby pushing the second transmission member 552 to swing back and forth along the axial direction of the crushing rollers 52. In turn, the second transmission member 552 can push the cleaning brushes 541 to swing back and forth along the axial direction of the crushing rollers 52 to remove and scrape away the gravel adhering to the crushing rollers 52.

[0055] For example, such as Figure 9As shown, the first transmission component 551 is an elastic ball 5511 mounted on the connecting shaft 53. There are at least two elastic balls 5511 arranged at circumferential intervals along the connecting shaft 53. The second transmission component 552 includes a connecting bar 5521 and a stop rod 5522. The lower end of the stop rod 5522 has a convex ball 55221. The convex ball 55221 and the elastic ball 5511 are arranged axially along the connecting shaft 53, and the convex ball 55221 is located on the movement path of the elastic ball 5511. When the connecting shaft 53 rotates, due to the elasticity and flexibility of the elastic ball 5511, it can drive the stop rod 5522 to move in the front-back direction of the device. The upper end of the stop rod 5522 is connected to the connecting bar 5521, which extends in the front-back direction of the device and is connected to two cleaning brushes 541, thereby driving the cleaning brushes 541 to move back and forth.

[0056] like Figure 9 As shown, the second cleaning assembly 54 also includes a crossbar 542 extending along the front-rear direction of the device. The crossbar 542 is fixed relative to the bearing housing 56. Multiple cleaning brushes 541 are arranged at intervals along the length of the crossbar 542. Springs are provided at the mating positions of the cleaning brushes 541 and the crossbar 542, and the cleaning brushes 541 can slide along the length of the crossbar 542. When the connecting bar 5521 moves the cleaning brushes 541, the cleaning brushes 541 can reciprocate back and forth under the action of the springs, thereby removing and scraping away the gravel adhering to the crushing roller 52.

[0057] It is understandable that, such as Figure 9 As shown, the rotation of the crushing roller 52 drives the rotation of the elastic ball 5511. The elastic ball 5511 abuts against the protruding ball 55221 on the push rod 5522, allowing the push rod 5522 to move back and forth. The push rod 5522 drives the connecting bar 5521 to move back and forth, and the connecting bar 5521 drives the cleaning brush 541 to move back and forth. The cleaning brush 541 scrapes away the gravel adhering to the crushing roller 52, effectively removing or scraping away the gravel adhering to the crushing roller 52, preventing the accumulation and blockage of gravel, thereby improving operating efficiency and stability, reducing maintenance frequency and the risk of equipment damage, and reducing production downtime and maintenance costs.
