Description

Technical Field

[0001] This invention relates to the field of support drilling grouting equipment, specifically an energy-saving soft rock support drilling grouting device and method. Background Technology

[0002] The focus of soft rock tunnel support should be on fully utilizing and leveraging its self-supporting capacity. The support principle is: based on the different properties of the rock strata and the different sources of ground pressure, starting from analyzing the basic laws of ground pressure activity, and using information-based design methods, the support system and construction process are continuously adapted to the deformation of the surrounding rock in order to control the deformation of the surrounding rock and maintain the stability of the tunnel. Therefore, it is necessary to use support drilling and grouting equipment for borehole support.

[0003] In the prior art, such as the application with application number CN202011197957.1 (IPC classification number E21B7 / 00) entitled "A Grouting Support Type Drill-Anchor Integrated Machine and Anchoring Method," the present invention includes an anchor rod and a driving device. The anchor rod extends between a first end and a second end. A cutter head is provided at the second end of the anchor rod. The driving device is detachably connected to the first end and can drive the anchor rod to rotate, thereby driving the cutter head to drill an anchor hole in the ground. A through hole is provided on the anchor rod, extending along the direction of the anchor rod. A soil removal device is connected in the through hole. The soil removal device rotates under the drive of the driving device to discharge the drilled soil through a soil discharge hole. The soil discharge hole is located on the outer peripheral wall of the first end of the anchor rod and communicates with the through hole. Under the drive of the driving device, the anchor rod and the soil removal device rotate relative to each other, and the cut soil is discharged from the anchor hole while drilling. After drilling, the driving device and the soil removal device are pulled out, and grout is injected into the anchor rod. The grout solidifies with the anchor rod to form an integral anchor.

[0004] However, in existing technologies, such as the grouting support type drilling and anchoring integrated machine mentioned in application number CN202011197957.1, although it can perform support after drilling anchor holes, reducing the pre-drilling process, improving anchoring efficiency, and reducing anchoring costs, it cannot drill holes around the inside of the anchor hole. As a result, after the grout is injected into the anchor hole and solidifies, the support effect may be unstable because there is no protrusion on the outside of the anchor rod. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving soft rock support drilling grouting device and method to solve the problems mentioned in the background art.

A rod corresponding to the through hole is fixed on the blocking plate. A second hinge block is fixed on the blocking plate. A connecting block is hinged to the second hinge block. A first hinge block is hinged to one end of the connecting block. A first limiting ring is fixed on the first hinge block. A moving block connected to the limiting assembly is sleeved on the first limiting ring. A threaded hole is opened inside the moving block. A threaded rod connected to the drilling mechanism is threaded inside the threaded hole. A connecting rod connected to the driving mechanism is fixed on the threaded rod.

[0008] Preferably, the drilling mechanism includes a drilling assembly, a soil conveying assembly, and a soil discharge assembly;

[0009] The drilling assembly includes a cup-shaped cutter head and a sleeve block. The cup-shaped cutter head is fixed to the bottom of the anchor rod, and the sleeve block is fixed to the upper end of the anchor rod. The sleeve block has a blocking opening and a top opening inside. A push rod that is connected to the drive mechanism is sleeved inside the blocking opening.

[0010] Preferably, the soil conveying assembly includes a rotating rod fixed to a threaded rod, and a helical blade located inside the anchor rod is fixed on the rotating rod.

[0011] Preferably, the soil discharge assembly includes a fixed pipe fixed to the drive mechanism, the lower end of the fixed pipe being movably connected to the anchor rod, a side pipe fixed on the fixed pipe located below the threaded rod, a convex ring being movably sleeved inside the side pipe, and a soil discharge pipe movably connected to the side pipe being fixed on the convex ring.

[0012] Preferably, the drive mechanism includes a control component, a drive component, and a reversing component;

[0013] The drive assembly includes a control box fixed to a fixed pipe, an electric motor fixed inside the control box, a handle fixed on the control box, a first gear connected to the electric motor, and the first gear fixedly connected to a connecting rod.

[0014] Preferably, the reversing assembly includes a through-hole opened inside the fixed tube, a second gear is movably sleeved inside the through-hole, a convex rod with a limit sleeve inside the control box is fixed on the second gear, one end of the second gear is meshed with the first gear, and the other end of the second gear is meshed with an internal gear ring fixedly connected to the push rod, and a second limit ring is fixed on the internal gear ring and sleeved inside the control box.

[0015] Preferably, the control component includes a start button, a forward button, and a reverse button fixed on the control box, and the start button, forward button, and reverse button are all electrically connected to the motor through the control box.

[0016] Preferably, the limiting component includes a limiting hole opened inside the control box, and a vertical rod fixed to the moving block is movably sleeved inside the limiting hole.

[0017] Preferably, the extrusion assembly includes a rigid spring fixed to the first gear, the lower end of which is movably connected to the moving block.

[0018] A method for an energy-saving soft rock support drilling grouting device includes the following steps:

[0019] S1. First, insert multiple baffles into the side groove, so that the rotating rod is inserted into the inside of the anchor rod as a whole. Then, insert the lower end of the push rod into the inside of the baffle through the top opening, and rotate the push rod to contact and connect with the side wall at one end of the baffle.

[0020] S2. Then start the motor, so that the first gear drives the anchor rod to reverse through the reversing component and the push rod and sleeve block, thereby causing the cup-shaped cutter head to cut the soil layer to drill holes and collect the excavated soil in the anchor rod. At the same time, the first gear drives the rotating rod and the spiral blade to rotate forward through the driving drilling component, and transports the excavated soil to the discharge pipe for discharge.

[0021] S3. When the cup-shaped cutter head drills to the appropriate position, the first gear is driven to reverse by the motor. The first gear drives the threaded rod to reverse through the connecting rod, so that the threaded rod drives the moving block to move downward through the threaded hole, and the limiting component limits the moving block. Then, the first limiting ring drives the blocking plate to move along the inner wall of the side groove through the first hinge block and the connecting block and the second hinge block, so that the rod on the blocking plate passes through the through hole and inserts into the soil around it to drill holes around the perimeter.

[0022] S4. After drilling, the moving block is reset by the motor, so that the insertion rod is disengaged from the inside of the through hole. Then, the push rod is rotated to align with the top opening. After alignment, the blocking plate and the rotating rod are pulled out separately by the control box.

[0023] S5. After pulling out, grout is injected into the anchor rod, so that the grout inside the anchor rod is discharged from the through hole into the hole drilled by the insertion rod to solidify, until a small amount of grout overflows from the top of the anchor rod, at which point the grouting is stopped.

[0024] The beneficial effects of this invention are:

[0025] 1. This invention, by setting up a blocking plate, insert rod, and moving block, uses a motor to drive the first gear to reverse, and the first gear drives the threaded rod to reverse through the connecting rod. This causes the threaded rod to move the moving block downwards through the compression of the threaded hole and the rigid spring. In turn, the first limiting ring moves the blocking plate along the inner wall of the side groove through the first hinge block and the connecting block and the second hinge block. This allows the insert rod on the blocking plate to pass through the through hole and insert into the surrounding soil to drill holes around the perimeter. As a result, when the grout solidifies, there will be many protrusions on the outer surface of the anchor rod, which makes the overall support effect of the anchor rod after the grout solidifies more solid.

[0026] 2. This invention, by setting up a push rod, a sleeve block, and a top opening, moves the moving block upwards via a drive motor, thereby disengaging the insertion rod from the inside of the through hole. Then, the control box is rotated by the handle until the push rod aligns with the top opening. After alignment, the blocking plate and the rotating rod are pulled out separately by the control box. After pulling them out, grout is injected into the anchor rod until a small amount of grout overflows from the top of the anchor rod, at which point the grouting stops. This design achieves the purpose of facilitating the disassembly of the control box and improving efficiency.

[0027] 3. This invention, by setting up a first gear, a second gear, and an internal gear ring, and by starting the motor, causes the first gear to drive the internal gear ring to reverse through the second gear. This causes the internal gear ring to drive the anchor rod to reverse through the blocking port and the sleeve block, thereby causing the cup-shaped cutter head to cut the soil layer to drill a hole and collect the excavated soil inside the anchor rod. At the same time, the first gear drives the threaded rod to rotate forward through the connecting rod. This causes the threaded rod to drive the spiral blade to rotate forward through the rotating rod to transport the excavated soil inside the anchor rod to the discharge pipe for discharge. This design achieves the purpose of self-drilling anchor holes for support, reducing the pre-drilling process, improving anchoring efficiency, and saving energy. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] An energy-saving soft rock support drilling grouting device is a drilling grouting reinforcement equipment for the purpose of energy-saving mine drilling support, with IPC classification number E21B7 / 00;

[0041] like Figures 1 to 9 As shown, it includes an anchor rod 1, which includes a driving mechanism, a drilling mechanism, and a four-sided drilling mechanism. The four-sided drilling mechanism includes a limiting component, a pressing component, and a driving drilling component.

[0042] The driving drilling assembly includes a through hole 2 and a side groove 3 inside the anchor rod 1. A blocking plate 4 is sleeved inside the side groove 3. A rod 5 corresponding to the through hole 2 is fixed on the blocking plate 4. A second hinge block 17 is fixed on the blocking plate 4. A connecting block 16 is hinged on the second hinge block 17. A first hinge block 15 is hinged to one end of the connecting block 16. A first limiting ring 14 is fixed on the first hinge block 15. A moving block 11 connected to the limiting assembly is sleeved on the first limiting ring 14. A threaded hole 12 is opened inside the moving block 11. A threaded rod 13 connected to the drilling mechanism is threaded inside the threaded hole 12. A connecting rod 10 connected to the driving mechanism is fixed on the threaded rod 13. The inner diameter of the connecting rod 10 is smaller than that of the threaded rod 13.

[0043] The drive assembly drives the connecting rod 10 to rotate, which in turn causes the connecting rod 10 to drive the moving block 11 to move downward through the threaded rod 13, the limiting assembly, and the threaded hole 12. This causes the moving block 11 to drive the first hinge block 15 to move downward through the first limiting ring 14. This causes the first hinge block 15 to drive the blocking plate 4 to move along the inner wall of the side groove 3 through the connecting block 16 and the second hinge block 17. This causes the insert rod 5 on the blocking plate 4 to pass through the through hole 2 and insert into the surrounding soil to make holes around the perimeter.

[0044] like Figures 1 to 2 As shown, the drilling mechanism includes a drilling assembly, a soil conveying assembly, and a soil discharge assembly;

[0045] The drilling assembly includes a cup-shaped cutter head 22 and a sleeve block 34. The cup-shaped cutter head 22 is fixed to the bottom of the anchor rod 1, and the sleeve block 34 is fixed to the upper end of the anchor rod 1. The sleeve block 34 has a blocking port 35 and a top port 36 inside. The blocking port 35 is fitted with a push rod 33 that is connected to the drive mechanism for transmission.

[0046] The drive mechanism causes the push rod 33 to rotate, which in turn causes the push rod 33 to drive the sleeve block 34 to rotate through the blocking port 35. This causes the sleeve block 34 to drive the bowl-shaped cutter head 22 to cut the soil layer and drill holes through the anchor rod 1, and collect the cut soil inside the anchor rod 1.

[0047] like Figure 2 and Figure 5 As shown, the soil conveying assembly includes a rotating rod 20 fixed to the threaded rod 13, and a spiral blade 21 located inside the anchor rod 1 is fixed on the rotating rod 20.

[0048] When the threaded rod 13 rotates, it will cause the spiral blade 21 to rotate through the rotating rod 20, thereby causing the spiral blade 21 to transport the slag inside the anchor rod 1 to the soil discharge assembly at the upper end.

[0049] like Figure 4As shown, the soil discharge assembly includes a fixed pipe 24 fixed to the drive mechanism. The lower end of the fixed pipe 24 is movably connected to the anchor rod 1. A side pipe 25 located below the threaded rod 13 is fixed on the fixed pipe 24. A convex ring 26 is movably sleeved inside the side pipe 25. A soil discharge pipe 27 movably connected to the side pipe 25 is fixed on the convex ring 26.

[0050] The design of the convex ring 26 and the soil discharge pipe 27 allows the soil discharge pipe 27 to rotate in the direction of soil discharge according to the soil discharge situation, making it more convenient for the device to discharge soil.

[0051] like Figure 6 As shown, the drive mechanism includes a control component, a drive component, and a reversing component;

[0052] The drive assembly includes a control box 6 fixed to the fixed tube 24, a motor 8 fixed inside the control box 6, a handle 7 fixed on the control box 6, a first gear 9 connected to the motor 8, and the first gear 9 fixedly connected to the connecting rod 10.

[0053] The operation of the electric motor 8 will cause the first gear 9 to drive the connecting rod 10 to rotate, thereby achieving the purpose of rotating the connecting rod 10.

[0054] like Figure 2 , Figure 4 and Figure 6 As shown, the reversing assembly includes a through-hole 28 opened inside the fixed tube 24. A second gear 29 is movably sleeved inside the through-hole 28. A convex rod 30 with a limit sleeve inside the control box 6 is fixed on the second gear 29. One end of the second gear 29 is meshed with the first gear 9. The other end of the second gear 29 is meshed with an internal gear ring 32 fixedly connected to the push rod 33. A second limit ring 31 with a sleeve inside the control box 6 is fixed on the internal gear ring 32.

[0055] Through the interaction between the second gear 29 and the internal gear ring 32 and the first gear 9, when the first gear 9 rotates, it causes the first gear 9 to drive the internal gear ring 32 to reverse through the second gear 29, thereby enabling the anchor rod 1 and the rotating rod 20 to drill holes and transport soil simultaneously.

[0056] like Figure 1 As shown, the control component includes a start button 37, a forward button 38, and a reverse button 39 fixed on the control box 6. The start button 37, the forward button 38, and the reverse button 39 are all electrically connected to the motor 8 through the control box 6.

[0057] By designing the start button 37, the forward button 38, and the reverse button 39, the start button 37 can control the motor 8 to start, while the forward button 38 and the reverse button 39 can control the motor 8 to rotate in both directions, thereby achieving the purpose of controlling the motor 8.

[0058] like Figure 6 As shown, the limiting component includes a limiting hole 19 opened inside the control box 6, and a vertical rod 18 fixed on the moving block 11 is movably sleeved inside the limiting hole 19.

[0059] The design of the vertical rod 18 and the limiting hole 19 will limit the movement block 11, thereby achieving the purpose of limiting the movement block 11.

[0060] like Figure 7 As shown, the extrusion assembly includes a rigid spring 23 fixed to the first gear 9, and the lower end of the rigid spring 23 is movably connected to the moving block 11.

[0061] The rigid spring 23 is designed to press the threaded hole 12 on the moving block 11 into close contact with the threaded rod 13, so that when the threaded rod 13 rotates, it can drive the moving block 11 to move as a whole through the threaded hole 12.

[0062] A method for an energy-saving soft rock support drilling grouting device includes the following steps:

[0063] S1. First, insert multiple baffle plates 4 into the side groove 3, so that the rotating rod 20 is inserted into the interior of the anchor rod 1 as a whole. Then, insert the lower end of the push rod 33 into the interior of the baffle 35 through the top opening 36, and rotate the push rod 33 to contact and connect with the side wall of one end of the baffle 35.

[0064] S2. Then start the motor 8, so that the first gear 9 drives the anchor rod 1 to reverse through the reversing assembly and the push rod 33 and the sleeve block 34, thereby causing the cup-shaped cutter head 22 to cut the soil layer to drill holes and collect the slag in the anchor rod 1. At the same time, the first gear 9 drives the rotating rod 20 and the spiral blade 21 to rotate forward through the driving drilling assembly, and transports the slag to the discharge pipe 27 for discharge.

[0065] S3. When the cup-shaped cutter head 22 drills to the appropriate position, the motor 8 drives the first gear 9 to reverse. The first gear 9 drives the threaded rod 13 to reverse through the connecting rod 10, so that the threaded rod 13 drives the moving block 11 to move downward through the threaded hole 12, and the limiting component limits the moving block 11. Then, the first limiting ring 14 drives the blocking plate 4 to move along the inner wall of the side groove 3 through the first hinge block 15 and the connecting block 16 and the second hinge block 17, so that the insert rod 5 on the blocking plate 4 passes through the through hole 2 and inserts into the soil around it to drill holes around it.

[0066] S4. After drilling, the moving block 11 is reset by the motor 8, so that the insertion rod 5 is disengaged from the inside of the through hole 2. Then, the push rod 33 is rotated to correspond with the top opening 36. After the correspondence, the blocking plate 4 and the rotating rod 20 are pulled out by the control box 6.

[0067] S5. After pulling out, grout is injected into the anchor rod 1, so that the grout inside the anchor rod 1 is discharged from the through hole 2 into the hole drilled by the insertion rod 5 to solidify, until a small amount of grout overflows from the upper end of the anchor rod 1, at which point the grouting is stopped.

[0068] Working principle:

[0069] In use, the motor 8 is started by pressing the start button 37 and the forward rotation button 38 in sequence. This causes the first gear 9 to drive the internal gear ring 32 to reverse through the second gear 29. The internal gear ring 32 then drives the anchor rod 1 to reverse through the blocking port 35 and the sleeve block 34. This causes the cup-shaped cutter head 22 to cut the soil layer and drill holes, collecting the excavated soil inside the anchor rod 1. At this time, the anchor rod 1 will drive the second hinge block 17 to rotate through the side groove 3 and the blocking plate 4. The second hinge block 17 then drives the first limiting ring 14 to rotate along the inner wall of the moving block 11 through the connecting block 16 and the first hinge block 15. Simultaneously, the first gear 9... The connecting rod 10 drives the threaded rod 13 to rotate forward, which in turn causes the threaded rod 13 to drive the moving block 11 to move upward through the threaded hole 12, compressing the rigid spring 23. This causes the vertical rod 18 and the limiting hole 19 to limit the moving block 11. Since the connecting rod 10 has a smaller inner diameter than the threaded rod 13, the threaded rod 13 cannot continue to drive the moving block 11 to move upward. Then, the threaded rod 13 drives the spiral blade 21 to rotate forward through the rotating rod 20, which transports the slag inside the anchor rod 1 to the discharge pipe 27 for discharge. This design achieves the goals of self-drilling anchor holes for support, reducing pre-drilling procedures, improving anchoring efficiency, and saving energy.

[0070] When the cup-shaped cutter head 22 drills to the appropriate position, pressing the reverse button 39 drives the motor 8 to reverse the first gear 9. The first gear 9, through the connecting rod 10, drives the threaded rod 13 to reverse, thereby causing the threaded rod 13 to move the moving block 11 downwards through the compression of the threaded hole 12 and the rigid spring 23. This causes the vertical rod 18 to move along the inner wall of the limiting hole 19, which in turn causes the first limiting ring 14 to move along the inner wall of the side groove 3 through the first hinge block 15 and the connecting block 16 and the second hinge block 17. At the same time, the first gear 9 will move along the inner wall of the side groove 3 through the second gear 22. 9 and the internal toothed ring 32 drive the push rod 33 along the inner wall of the blocking port 35 until the push rod 33 contacts the side wall of the other end of the blocking port 35 and stops. This will cause the insertion rod 5 on the blocking plate 4 to pass through the through hole 2 and be inserted into the surrounding soil to make holes around the perimeter. With this design, when grout is injected into the anchor rod 1 later, the grout inside the anchor rod 1 will be discharged from the through hole 2 into the hole drilled by the insertion rod 5 to solidify. As a result, when the grout solidifies, there will be many protrusions on the outer surface of the anchor rod 1, which will make the overall support effect of the anchor rod 1 after the grout solidifies more solid, thereby achieving the purpose of strengthening the grout injection support effect.

[0071] After drilling, the moving block 11 is reset by the drive motor 8, so that the insertion rod 5 is disengaged from the through hole 2. Then, the control box 6 is rotated by the handle 7 until the push rod 33 corresponds with the top opening 36. After the correspondence, the blocking plate 4 and the rotating rod 20 are pulled out by the control box 6. After pulling them out, grout is injected into the anchor rod 1, so that the grout inside the anchor rod 1 is discharged from the through hole 2 into the hole drilled by the insertion rod 5 to solidify. Grouting is stopped when a small amount of grout overflows from the top of the anchor rod 1. This design achieves the purpose of convenient disassembly of the control box 6 and improved efficiency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.

10. A method for an energy-saving soft rock support drilling grouting device according to any one of claims 1 to 9, the method comprising the following steps: S1. First, insert multiple baffles (4) into the side groove (3) so that the rotating rod (20) is inserted into the anchor rod (1) as a whole. Then, insert the lower end of the push rod (33) into the baffle (35) through the top opening (36) and rotate the push rod (33) to contact and connect with the side wall of one end of the baffle (35). S2. Then start the motor (8), so that the first gear (9) drives the anchor rod (1) to reverse through the reversing assembly and push rod (33) and sleeve block (34), thereby causing the cup-shaped cutter head (22) to cut the soil layer to drill holes and collect the slag in the anchor rod (1). At the same time, the first gear (9) drives the rotating rod (20) and spiral blade (21) to rotate forward through the driving drilling assembly, and transports the slag to the discharge pipe (27) for discharge. S3. When the cup-shaped cutter head (22) drills to the appropriate position, the first gear (9) is driven to reverse by the motor (8). The first gear (9) drives the threaded rod (13) to reverse through the connecting rod (10), so that the threaded rod (13) drives the moving block (11) to move downward through the threaded hole (12), and the limiting component limits the moving block (11). Then, the first limiting ring (14) drives the blocking plate (4) to move along the inner wall of the side groove (3) through the first hinge block (15) and the connecting block (16) and the second hinge block (17), so that the insert rod (5) on the blocking plate (4) passes through the through hole (2) and inserts into the soil around it to drill holes around it. S4. After drilling, the moving block (11) is reset by the motor (8), so that the insert rod (5) is disengaged from the inside of the through hole (2). Then, the push rod (33) is rotated to correspond with the top opening (36). After corresponding, the blocking plate (4) and the rotating rod (20) are pulled out by the control box (6). S5. After pulling out, grout is injected into the anchor rod (1) so that the grout inside the anchor rod (1) is discharged from the through hole (2) into the hole drilled in the insertion rod (5) to solidify until a small amount of grout overflows from the top of the anchor rod (1), at which point the grouting is stopped.
