Description

Technical Field

[0001] This invention relates to the field of soft rock support technology, and in particular to a soft rock seismic anchoring support structure. Background Technology

[0002] When performing engineering support in soft rock strata, the low strength, easy deformation, and poor self-stabilization of soft rock make it prone to significant deformation or even instability after excavation or exposure to external loads (such as earthquakes). Especially under dynamic loads like earthquakes, the dynamic response of soft rock is more complex, often leading to problems such as anchoring system failure and insufficient stability of the support structure. Currently, traditional anchoring support structures used in soft rock often suffer from insufficient anchoring depth, weak lateral anchoring capacity, and low installation efficiency. During construction, it is usually necessary to install anchor bolts one by one and perform lateral drilling to enhance the anchoring effect. This process is cumbersome, labor-intensive, and severely impacts the construction efficiency and overall seismic performance of the support structure. Therefore, there is an urgent need to develop an anchoring support structure suitable for soft rock strata, possessing good seismic performance and easy installation, to improve the safety and stability of engineering structures in soft rock formations.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The present invention, through the design of the anchoring structure and control mechanism, facilitates the synchronous extension of multiple insertion cylinders and their insertion into pre-drilled holes in soft rock cavities. This avoids workers from sequentially inserting insertion cylinders into different pre-drilled holes, thus solving the problem of high labor input and numerous operations caused by workers independently inserting anchor rods into pre-drilled holes. This design reduces the labor intensity of workers and increases the installation speed of insertion cylinders, thereby accelerating the anchoring support progress of soft rock cavities.

[0018] 2. The design of the fastener makes it easy to insert the plug rod into the bottom of the soft rock hole to fix the support base, effectively preventing the support base from shifting and improving the support stability of the support plate.

[0019] 3. Through the design of the connecting mechanism, the support plate, support seat and connecting seat are fixedly connected and fixed to the side wall of the soft rock hole, which effectively improves the installation stability of the support components and improves the anchoring support effect of the soft rock hole.

[0020] 4. The expansion mechanism enables the second insertion rod to move laterally, facilitating its insertion into the side wall of the pre-drilled hole. Combined with the rotating component, this allows for rotation during the lateral movement, enabling lateral drilling within the pre-drilled hole. This reduces resistance encountered during insertion, making it easier to insert the second insertion rod into the soft rock hole. It also solves the problem of workers being unable to perform lateral drilling within the pre-drilled hole, effectively enhancing the connection stability between the insertion rod and the pre-drilled hole, improving the tightness of the connection, and ultimately enhancing the anchoring support effect for the soft rock hole.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Please combine Figures 1 to 10 This embodiment of a soft rock seismic anchoring support structure includes several support components. Adjacent support components are connected by two symmetrically arranged connecting mechanisms. Each support component includes two support seats 6. Each support seat 6 has a fixing device inside. The top ends of the two support seats 6 are connected by a support plate 1. The top two sides of the support seat 6 and the bottom two sides of the support plate 1 are provided with bases 22. The top end of the support plate 1 is provided with a receiving cavity 2. The bottom two sides of the receiving cavity 2 are symmetrically provided with slots 3. The top end of the support plate 1 is provided with a cover plate 4. The two ends of the cover plate 4 are provided with a card plate 5 located inside the slot 3. The top end of the cover plate 4 is provided with five openings 7 at equal intervals. The bottom end of the cover plate 4 is provided with a rotating groove 8 connected to the openings 7. Each opening 7 is provided with a plug-in mechanism. The receiving cavity 2 is provided with a control mechanism connected to the five plug-in mechanisms.

[0035] The insertion mechanism includes an internally threaded cylinder 9 rotatably installed inside the rotating groove 8. Both the rotating groove 8 and the internally threaded cylinder 9 have a T-shaped vertical section. A bevel gear 10 is fixedly sleeved on the bottom of the outer wall of the internally threaded cylinder 9. An insertion rod cylinder 11 is threadedly connected inside the through-hole 7. The top of the insertion rod cylinder 11 is conical. The outer wall of the insertion rod cylinder 11 is symmetrically provided with sliding grooves 13. A limiting block 12 that slides on the inner wall of the sliding groove 13 is fixedly connected to the inner wall of the through-hole 7. An anchoring structure is provided inside each insertion rod cylinder 11. Through the design of the anchoring structure and control mechanism, it is easy to control multiple insertion rod cylinders 11 to extend synchronously and be inserted into the pre-drilled holes in the soft rock cavity. This avoids workers from inserting the insertion rod cylinders 11 into different pre-drilled holes in sequence. Therefore, this design effectively improves the installation speed of the insertion rod cylinders 11 and speeds up the anchoring support progress of the soft rock cavity.

[0036] The control mechanism includes a stabilizing rod 15 fixed to the inner wall of the support plate 1. The longitudinal section of the stabilizing rod 15 is rectangular, and the stabilizing rod 15 is arc-shaped. An arc-shaped plate 14 is slidably sleeved on the outer wall of the stabilizing rod 15. A conical toothed plate 16 is fixedly connected to one side of the arc-shaped plate 14. The conical toothed plate 16 meshes with a bevel gear 10. An arc-shaped toothed plate 17 is fixedly connected to the bottom end of the arc-shaped plate 14. A control unit connected to the arc-shaped toothed plate 17 is installed on the support plate 1. Through the design of the control mechanism, it is easy to synchronously control the movement of the insertion rod cylinder 11, effectively avoiding the need for workers to install anchor rods separately in pre-drilled holes, thereby reducing the labor intensity of workers.

[0037] The control unit includes a mounting shaft 18 rotatably mounted on the inner wall of the support plate 1. The support plate 1 has a slot 30. A worm gear 19 and a gear 20 are fixedly sleeved on the outer wall of the mounting shaft 18. The gear 20 meshes with the arc-shaped toothed plate 17 and is located inside the slot 30. A worm 21 meshes with the worm gear 19 and is rotatably mounted on the support plate 1. It should be noted that one end of the worm 21 is connected to a power source, such as a motor, or rotated by a worker, thus effectively providing power for the rotation of the worm 21. This design facilitates the sliding of the arc-shaped plate 14 on the stabilizing rod 15, thereby providing power for the extension movement of multiple insertion rod cylinders 11. This facilitates the extension of the insertion rod cylinders 11 and their insertion into the pre-drilled holes, solving the problem of high labor input and numerous operations caused by workers sequentially inserting anchor rods into the pre-drilled holes. Therefore, this design effectively reduces labor input and accelerates the progress of anchoring and supporting soft rock holes.

[0038] The fixture includes an electric push rod 31 installed on the inner wall of the top of the support base 6. The output shaft of the electric push rod 31 is connected to a plug rod 32 that passes through the bottom of the support base 6. The bottom end of the plug rod 32 is a cone. The fixture design makes it easy for the plug rod 32 to be inserted into the bottom of the soft rock hole, thereby fixing the support base 6, effectively preventing the support base 6 from shifting, and improving the support stability of the support plate 1.

[0039] The connecting mechanism includes a connecting seat 23 located between two support plates 1. Both ends of the two connecting seats 23 are provided with a sleeve groove 24 that fits onto the outer wall of the two bases 22. The inner wall of the sleeve groove 24 contacts the outer wall of the base 22. The two bases 22 and the connecting seats 23 are connected by bolts 25. The adjacent sides of two connecting seats 23 are provided with grooves 26. The sidewall of the connecting seat 23 is provided with through holes 29 at equal intervals that communicate with the grooves 26. Anchor rods 27 are inserted into the through holes 29. One end of the anchor rod 27 is conical and the other end of the anchor rod 27 is connected to an anchor seat 28 located inside the groove 26. Through the design of the connecting mechanism, the support plates 1, support seats 6 and connecting seats 23 are fixedly connected and fixed to the sidewall of the soft rock hole, which effectively improves the installation stability of the support components and improves the anchoring support effect for the soft rock hole.

[0040] The anchoring structure includes two through holes 33 symmetrically opened on the top of both sides of the insert cylinder 11. The inner wall of the insert cylinder 11 is fixedly connected to a fixing rod 34 located below the two through holes 33. The fixing rod 34 has a rectangular structure and two symmetrically arranged sliding plates 35 slide on the fixing rod 34. The top of each sliding plate 35 is fixedly connected to a socket 36. Each socket 36 is rotatably mounted with an insert rod 37 that passes through the through hole 33. One end of each insert rod 37 is conical. The insert cylinder 11 and the insert rod 37 are connected by a rotating component. The interior of the insert cylinder 11 is provided with an expansion mechanism connected to the two sliding plates 35. The expansion mechanism can realize the lateral movement of the insert rod 37, which facilitates the lateral insertion of the insert rod 37 into the side wall of the reserved hole, increases the connection stability between the insert cylinder 11 and the reserved hole, and thus improves the connection tightness between the insert cylinder 11 and the soft rock hole, and improves the anchoring support effect of the soft rock hole.

[0041] The rotating component includes a limiting rod 39 fixed to the top of the insertion rod cylinder 11. The outer wall of the second insertion rod 37 is provided with a threaded groove 38. The bottom end of the limiting rod 39 extends into the interior of the threaded groove 38, and the limiting rod 39 slides in contact with the threaded groove 38. The design of the rotating component facilitates the rotation of the second insertion rod 37 during lateral movement, and facilitates the drilling operation of the second insertion rod 37 in the reserved hole, providing convenience for the second insertion rod 37 to be inserted into the side wall of the reserved hole in the soft rock cavity.

[0042] The expansion mechanism includes a rotating shaft 45 rotatably mounted on the inner wall of the insertion rod cylinder 11. A gear 46 and a cam 47 are fixedly sleeved on the rotating shaft 45. The cam 47 has an elliptical structure, and the outer wall of the long end of the cam 47 slides in contact with the side of the two sliding plates 35 that are close to each other. The bottom end of the fixed rod 34 is provided with a lifting transmission unit connected to the gear 46. The inner wall of the insertion rod cylinder 11 is symmetrically equipped with a trigger unit connected to the lifting transmission unit. The lifting transmission unit includes a fixed cylinder 40 fixed to the middle position of the bottom end of the fixed rod 34. The inner wall of the fixed cylinder 40 slides through the fixed cylinder. There is a lifting rod 41 with two symmetrical protrusions at its top. The inner wall of the fixed cylinder 40 has a sliding opening that slides in contact with the protrusions. The top of the lifting rod 41 is connected to the fixed cylinder 40 by a spring 42. A lifting block 43 is fixedly connected to the bottom of the lifting rod 41. The lifting block 43 has a frustum structure. A strip toothed plate 44 that meshes with a gear 46 is fixedly connected to the bottom of the lifting block 43. The triggering unit includes through holes 48 symmetrically opened on both sides of the internal threaded cylinder 9. The through holes 48 are connected to the sliding groove 13. Two stops are fixedly connected to the inner wall of the insertion rod cylinder 11. Both the plate 49 and the stop plate 49 have slidably inserted extrusion rods 50 extending into the through hole 48. One end of the outer wall of the extrusion rod 50 slides in contact with the outer wall of the limiting block 12. At the close ends of the two extrusion rods 50, push blocks 51 are fixedly connected to slide in contact with the outer wall of the lifting block 43. The push blocks 51 are trapezoidal blocks. Springs 52, connected to the stop plate 49 and the push blocks 51, are fitted onto each extrusion rod 50. Through the design of the trigger unit, when the insertion rod cylinder 11 extends into the reserved hole, the trigger unit is activated by the limiting block 12, facilitating the movement of the lifting block 43. 3. Extrusion is performed to activate the lifting transmission unit, which in turn activates the lifting control expansion mechanism of the strip toothed plate 44. This facilitates the rotation of the cam 47 to push the two fixed rods 34 away from each other, enabling the two insertion rods 37 to move laterally. In conjunction with the rotating component, the insertion rods 37 can rotate during the lateral movement, facilitating drilling operations on the inner wall of the pre-reserved hole. This provides convenience for the lateral insertion of the insertion rods 37 into the side wall of the pre-reserved hole, further enhancing the tightness of the connection between the insertion rod cylinder 11 and the pre-reserved hole, and improving the support stability of soft rock holes.

[0043] The implementation principle of a soft rock seismic anchoring support structure in this application embodiment is as follows: When installing the support components, the workers drill a reserved hole at the top of the soft rock hole that matches the insertion tube 11 using a drilling machine. Then, the workers place the cover plate 4 on the top of the support plate 1, so that the clamping plate 5 is clamped on the groove 3, thereby sealing the receiving cavity 2 with the cover plate 4. At the same time, the cover plate 4 will drive the bevel gear 10 to mesh with the bevel tooth plate 16. Then, the support plate 1 is lifted so that the top of the cover plate 4 and the top of the support plate 1 are in close contact with the top of the inner wall of the soft rock hole, thereby connecting the opening 7 with the reserved hole. Then, the two support seats 6 are placed at the bottom of the support plate 1 respectively, so that the two bases 22 are in close contact, thereby supporting the support plate 1 with the support seat 6, and supporting the soft rock hole with the support plate 1, the cover plate 4 and the support seat 6.

[0044] Next, the worm gear 21 is controlled to rotate, which drives the worm wheel 19 to rotate. The worm wheel 19 causes the mounting shaft 18 to rotate, which in turn drives the gear 20 to rotate. Through the meshing relationship between the gear 20 and the arc-shaped toothed plate 17, the arc-shaped toothed plate 17 pushes the arc-shaped plate 14 to slide outside the stabilizer 15. The arc-shaped plate 14 drives the conical toothed plate 16 to move. Through the meshing connection between the conical toothed plate 16 and multiple conical gears 10, it is easy for multiple conical gears 10 to rotate synchronously. The conical gears 10 drive the internal threaded cylinder 9 to rotate. Through the threaded connection between the internal threaded cylinder 9 and the insertion cylinder 11, as well as the sliding relationship between the limiting block 12 and the slide groove 13, the insertion cylinder 11 will move, allowing the insertion cylinder 11 to pass through the through-hole 7 and extend into the reserved hole.

[0045] During the upward movement of the insertion cylinder 11, the limiting block 12 slides in the slide groove 13. When the limiting block 12 contacts one end of the extrusion rod 50 and continues to move, the sliding relationship between the extrusion rod 50 and the limiting block 12 will extrude one end of the extrusion rod 50, facilitating the extrusion rod 50 to slide into the through hole 48. Consequently, the extrusion rod 50 will drive the push block 51 to move laterally, causing the second spring 52 to generate elastic force. When the insertion cylinder 11 moves into the reserved hole, the worm gear 21 stops working. At this time, the limiting block 12 is located on one side of the through hole 48. Through the mutual approach of the two push blocks 51 and their sliding relationship with the lifting block 43, the lifting block 43 will be subjected to extrusion force and move downward. The lifting block 43 will pull the lifting rod 41 downward inside the fixed cylinder 40, causing the first spring 42 to stretch. The lifting block 43 will drive the strip toothed plate 44 downward, through the strip toothed plate 44 and The meshing connection of gear 46 will cause gear 46 to drive the rotating shaft 45 to rotate, which in turn will drive the cam 47 to rotate. As a result, the outer wall of the long end of the cam 47 will contact the side wall of the slide plate 35 and push the slide plate 35 to slide on the fixed rod 34. The slide plate 35 will drive the insertion rod 37 to slide inside the through hole 33 through the socket 36. At the same time, through the sliding relationship between the limiting rod 39 and the threaded groove 38, the insertion rod 37 can rotate during the movement, so that the insertion rod 37 can drill the inner wall of the reserved hole. This effectively reduces the resistance encountered when inserting the insertion rod 37 laterally into the inner wall of the reserved hole, provides convenience for the insertion rod 37 to be inserted laterally into the side wall of the reserved hole, effectively enhances the tightness of the connection between the insertion rod cylinder 11 and the reserved hole, and improves the connection stability with the soft rock hole, thus effectively improving the support effect of the soft rock hole.

[0046] After installing two sets of support components at equal intervals, the workers drill holes in the sidewall of the soft rock borehole according to the spacing between two adjacent anchor rods 27. Then, the connecting seat 23 is inserted laterally, so that the sleeve grooves 24 on both sides of the connecting seat 23 are sleeved with the two bases 22. Bolts 25 are installed on the connecting seat 23 to fix the connecting seat 23 and the two bases 22, thereby fixing the support plate 1, support seat 6 and connecting seat 23. Next, the anchor rod 27 is passed through the through hole 29 and inserted into the reserved hole. An anchor rod seat 28 connected to one end of the anchor rod 27 is installed in the groove 26. The sidewall of the soft rock borehole is fixed through the connecting seat 23 and the anchor rod 27, effectively fixing the two sets of support components, thereby improving the stability of the anchor support for the soft rock borehole.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
