Description

Technical Field

[0001] The invention belongs to the technical field of tunnel construction and relates to tunnel drilling and grouting integrated construction equipment. Background Art

[0002] Grouting technology plays a crucial role in tunnel construction for surrounding rock reinforcement and water seepage control. Traditional construction techniques typically separate drilling and grouting into two separate steps: first, drilling the hole with a drill, followed by separate grouting operations. While this step-by-step approach can achieve the goals of surrounding rock reinforcement and water seepage control to a certain extent, it presents numerous challenges in actual construction, severely impacting efficiency and quality.

[0003] The traditional step-by-step operation model requires repeated positioning and disassembly of equipment, resulting in extended process transitions and significantly increased labor costs. Especially during tunnel roof operations, existing equipment lacks a stable support mechanism, making the positioning process cumbersome and time-consuming, further impacting construction efficiency. Furthermore, the step-by-step operation model cannot achieve a seamless transition between drilling and grouting, potentially delaying the timing of surrounding rock reinforcement, thereby impacting surrounding rock stability and construction safety. These issues are particularly prominent in complex geological conditions, limiting the efficiency and quality of tunnel construction.

[0004] In response to the problems existing in the above-mentioned prior art, the present invention proposes an integrated tunnel drilling and grouting construction equipment. This equipment is designed to simplify the construction process by integrating the drilling and grouting processes, reduce the number of equipment positioning and disassembly, thereby shortening the process connection time and reducing labor costs. At the same time, the equipment will be equipped with a stable support mechanism to improve the positioning efficiency and stability when operating on the tunnel top wall. In addition, the integrated design can ensure seamless connection between drilling and grouting, complete surrounding rock reinforcement in a timely manner, and avoid delays in reinforcement timing.

[0036] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0037] Example 1

[0038] Reference Figure 1-3 This integrated tunnel boring and grouting construction equipment features four wheels 2 symmetrically mounted on the bottom of a support frame 1, and two support discs 3 symmetrically fixedly mounted on the support frame 1. An adjustment mechanism is mounted on the support disc 3. This adjustment mechanism includes a shaft sleeve 4 that passes through the support disc 3 and is rotatably connected to the support disc 3. A rotating shaft 5 is fixedly mounted within the shaft sleeve 4. A mounting disc 6 is fixedly mounted on one end of the rotating shaft 5, which is used to connect to the drive mechanism. A toothed disc 38 is fixedly mounted on the other end of the rotating shaft 5. A driving arm 39 is fixedly mounted at an eccentric position on one side of the toothed disc 38. A handle 40 is rotatably connected to the bottom of one side of the driving arm 39. By pulling the handle 40, the driving arm 39 rotates, which in turn rotates the rotating shaft 5 through the toothed disc 38, thereby achieving rotational adjustment of the adjustment mechanism's direction of motion. This allows the excavation mechanism to be adjusted in direction, and the excavation mechanism's position to be adjusted according to the drilling location within the tunnel.

[0039] like Figure 2 and Figure 8 As shown, two support shafts 41 are symmetrically connected and rotatably extend through the support frame 1. A positioning arm 42 is fixedly mounted on one end of the support shaft 41. The positioning arm 42 is provided with a latching tooth 43, which is movably engaged with the toothed disc 38 to brake and position the toothed disc 38. A torsion spring 44 is mounted on the support shaft 41. The two ends of the torsion spring 44 are respectively fixedly connected to the other end of the support shaft 41 and one side of the support frame 1 via bolts. After the angle of the adjustment mechanism is adjusted by rotating the toothed disc 38, the positioning arm 42 is released. The torsion spring 44, which is in a stressed state, drives the support shaft 41 to rotate, driving the positioning arm 42 to move, causing the latching tooth 43 to engage with the toothed disc 38 and position it, thereby limiting the angle of the adjustment mechanism.

[0040] like Figure 1 、 Figure 4 and Figure 7As shown, the construction equipment also includes a driving mechanism, which includes two limit frames 7. The two limit frames 7 are respectively fixedly connected to the two mounting plates 6 by screws. The limit plates 8 are slidably connected inside the limit frames 7. The two limit plates 8 are fixedly installed with a connecting shaft 9 on the side close to each other. The top of one side of the two limit frames 7 is connected to the same power assembly, and the bottom of the two limit frames 7 is fixedly installed with the same base frame 31. The bottom of the power assembly is connected to the top of the base frame 31. The base frame 31 is penetrated by a threaded assembly. The bottom of the threaded assembly is connected to the excavation mechanism. The power assembly is connected to the threaded assembly. The grouting mechanism is installed on the top of the threaded assembly. The bottom of the grouting mechanism passes through the threaded assembly and is connected to the excavation mechanism.

[0041] like Figure 7 As shown, the power assembly includes a mounting frame 33, which is fixedly mounted on the top of one side of the two limiting frames 7. A drive motor 34 is fixedly mounted on the top of the mounting frame 33 by bolts. The output shaft of the drive motor 34 extends below the mounting frame 33 and is fixedly mounted with a transmission shaft 35. The bottom end of the transmission shaft 35 is rotatably connected to the top of the base frame 31. A gear column 36 is fixed to the transmission shaft 35 by a key connection. A driven gear 37 is installed on the threaded assembly, and the gear column 36 meshes with the driven gear 37. When the drive motor 34 is started, the transmission shaft 35 rotates, which in turn drives the gear column 36 to rotate. Under the meshing transmission action with the driven gear 37, the threaded assembly is driven to move. The gear column 36 is long, and when the driven gear 37 moves with the threaded assembly, the gear column 36 and the driven gear 37 are always kept in meshing state, thereby continuously driving the threaded assembly.

[0042] like Figure 7 As shown, the threaded assembly includes a nut 32 fixedly mounted on the top of a base frame 31. The nut 32 is threadedly connected to an externally threaded tube 12. The bottom end of the externally threaded tube 12 extends below the base frame 31 and is fixedly mounted with a connecting ring 16. The connecting ring 16 is connected to the excavation mechanism via a plurality of fixing bolts 18. The top end of the externally threaded tube 12 is connected to a grouting mechanism, which extends through the externally threaded tube 12. A driven gear 37 is fixedly mounted on the externally threaded tube 12. Upon receiving the driving force from the driven gear 37, the externally threaded tube 12 rotates, driving the excavation mechanism to rotate. At the same time, as the externally threaded tube 12 rotates, the threaded transmission between the nut 32 and the externally threaded tube 12 drives the externally threaded tube 12 to move linearly, thereby driving the excavation mechanism to move. This allows the excavation mechanism to maintain rotation and linear movement, facilitating the excavation of holes in the inner wall of the tunnel.

[0043] like Figure 7As shown, the grouting mechanism includes a liquid injection box 10 fixedly connected to two connecting shafts 9. An external pipe 11 is fixedly installed on the inner wall of one side of the liquid injection box 10. The top end of the external threaded pipe 12 extends into the liquid injection box 10 and is fixedly installed with a connecting plate 13. The connecting plate 13 is rotatably connected to the inner wall of the liquid injection box 10. A plurality of delivery pipes 14 are fixedly installed on the connecting plate 13 at equal intervals. The bottom end of the delivery pipe 14 passes through the external threaded pipe 12 and is fixedly installed with a plug 15. The plurality of plugs 15 are all connected to the excavation mechanism. After the external pipe 11 is connected to the delivery pipeline of the cement slurry, the cement slurry is transported and injected into the liquid injection box 10. After being transported by the plurality of delivery pipes 14, the cement slurry is transported into the excavation mechanism. The cement slurry is transported and discharged from the excavation mechanism to achieve grouting into the opened hole.

[0044] like Figure 5 As shown, the excavation mechanism includes a drill bit 19, which is a hollow structure. Rake teeth 20 are fixedly mounted on the outside of the drill bit 19 at equal intervals. Multiple mud discharge grooves 21 are defined on the outside of the drill bit 19 at equal intervals, spaced apart from the rake teeth 20. Second flow holes 30 are defined on the inner wall of the bottom of one side of the mud discharge grooves 21. A connecting assembly is installed within the drill bit 19 and connected to multiple fixing bolts 18. A dispersion assembly is installed through the connecting assembly and connected to multiple clamping tubes 27. After the connecting assembly is connected to the multiple fixing bolts 18, the drill bit 19 is connected to the connecting ring 16 to install the drill bit 19. The drill bit 19 rotates and moves synchronously with the externally threaded tube 12. Simultaneously, the dispersion assembly is docked with multiple plugs 15, allowing cement slurry delivered through the delivery pipe 14 to be injected into the excavated hole through the dispersion assembly and the multiple second flow holes 30.

[0045] The present application can be used in the field of tunnel construction technology, and can also be used in other fields applicable to the present application.

[0046] Example 2

[0047] refer to Figure 5-6Based on the improvement of Example 1, in this integrated tunnel drilling and grouting construction equipment, the connection assembly includes a mounting ring 22 fixedly mounted within the drill bit 19, a plurality of fixing bolts 18 all passing through the mounting ring 22 and connected to the mounting ring 22, a docking ring 23 fixedly mounted on the top of the mounting ring 22, a plurality of slots 24 being provided at equal intervals on the top of the docking ring 23, and a plurality of locating pins 17 fixedly mounted at equal intervals on the bottom of the connecting ring 16, the bottom ends of the locating pins 17 being inserted into and plugged into the corresponding slots 24, and the dispersion assembly passing through the docking ring 23 and connected to the inner wall of the docking ring 23. After docking the connecting ring 16 with the docking ring 23, the plurality of locating pins 17 are inserted into the corresponding slots 24, and then the fixing bolts 18 are passed through the mounting ring 22 and the connecting ring 16 to stably connect the mounting ring 22 and the connecting ring 16, stably and firmly connecting the drill bit 19 to the externally threaded pipe 12, so that the drill bit 19 can move stably with the externally threaded pipe 12.

[0048] The dispersion assembly includes a positioning ring 25 fixedly mounted within the docking ring 23. Multiple flow tubes 26 are fixedly mounted on the positioning ring 25 at equal intervals. A clamping tube 27 is fixedly mounted at the top of the flow tube 26, which is clamped to the corresponding plug 15. The bottom ends of the multiple flow tubes 26 are fixedly connected to a single annular tube 28, which is fixed to the inner wall of the drill bit 19. Multiple first flow holes 29 are formed on the inner side wall of the annular tube 28 at equal intervals. The first flow holes 29 communicate with corresponding second flow holes 30. After connecting the externally threaded tube 12 to the drill bit 19, the plug 15 is inserted into the corresponding clamping tube 27 and tightly clamped to the clamping tube 27. Cement slurry delivered through the delivery pipe 14 flows through the flow tube 26 into the annular tube 28, then flows through the multiple first flow holes 29 and the corresponding second flow holes 30 into the opening slot, achieving the purpose of rapid grouting.

[0049] When using the integrated tunnel boring and grouting equipment, the equipment is first transported to the tunnel construction site via the four wheels 2 at the bottom of the support frame 1 to ensure that the equipment is placed stably. The external pipe 11 in the grouting mechanism is then connected to the external cement slurry delivery pipe to ensure that the slurry can be smoothly delivered to the grouting tank 10. The positioning arm 42 is then manually pulled to overcome the elastic force of the torsion spring 44, causing the latching teeth 43 to separate from the toothed disc 38. The handle 40 is then pulled to rotate the driving arm 39, which in turn rotates the toothed disc 38, which in turn rotates the rotating shaft 5 within the sleeve 4, thereby rotating the mounting disc 6, thereby adjusting the direction of the adjustment mechanism and adjusting the direction of movement of the excavation mechanism to align it with the location where the hole is to be drilled in the tunnel. After the adjustment mechanism is adjusted, the positioning arm 42 is released, and the torsion spring 44 restores its elastic force, driving the support shaft 41 to rotate, driving the positioning arm 42 to move, causing the latching teeth 43 to re-engage with the toothed disc 38, braking and positioning the adjustment mechanism to ensure the stable position of the excavation mechanism.

[0050] Then start the driving motor 34 on the mounting bracket 33, and the output shaft of the driving motor 34 drives the transmission shaft 35 to rotate, and the transmission shaft 35 drives the gear column 36 to rotate. Since the gear column 36 is meshed with the driven gear 37, the transmission of the driven gear 37 can drive the externally threaded tube 12 to rotate. The externally threaded tube 12 rotates under the drive of the driven gear 37. At the same time, since the externally threaded tube 12 is threadedly connected to the nut 32, the externally threaded tube 12 can move linearly during the rotation process under the action of the threaded transmission with the nut 32. The connecting ring 16 at the bottom end of the externally threaded tube 12 is connected to the mounting ring 22 in the excavation mechanism by a plurality of fixing bolts 18, and the plurality of positioning pins 17 at the bottom of the connecting ring 16 are inserted into the plurality of slots 24 at the top of the mounting ring 22 to realize drilling. The head 19 is stably connected to the external threaded tube 12. Therefore, the rotation and linear movement of the external threaded tube 12 drive the drill bit 19 to rotate and move synchronously. The rake teeth 20 on the outside of the drill bit 19 drill holes on the inner wall of the tunnel. The mud residue generated during the excavation process can be discharged through the mud outlet 21. The cement slurry can be stably transported by the external mud pump, so that the cement slurry enters the injection tank 10 through the external pipe 11, and then is transported through the multiple delivery pipes 14 on the connecting plate 13. Since the plug 15 at the bottom end of the delivery pipe 14 is clamped with the clamping pipe 27 in the dispersion component, the cement slurry passes through the flow pipe 26 and the annular pipe 28 in turn, and then through the multiple first flow holes 29 and the multiple second flow holes 30 on the inner wall of the side of the annular pipe 28, and is injected into the excavated holes to realize the grouting operation.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
