Description

Technical Field

[0001] This invention relates to the field of tunnel construction, and in particular to an automatic collection and conveying device for under-excavation treatment of tunnel debris. Background Technology

[0002] Tunnel construction refers to the general term for the construction methods, technologies and management of tunnels and underground caverns. It is a complex and technology-intensive engineering process that usually involves multiple stages and links.

[0003] During tunnel construction, due to the need to traverse different strata and the complex and variable geological conditions, in order to avoid situations such as stratum collapse and mudslides during excavation when encountering karst areas, coal mine roadways, fault fracture zones, or sections with poor surrounding rock stability, which would affect the stability of the tunnel cross-section after construction, a conservative excavation scheme is usually adopted. After excavating the tunnel body using the conservative scheme, it is easy for the tunnel cross-section perimeter to be smaller than the design size, which is called tunnel under-excavation.

[0004] In existing technologies, when under-excavation of a tunnel occurs, manual labor using shovels, picks, crowbars, and other auxiliary rock drilling equipment is typically employed to further excavate the tunnel and ensure it meets design requirements. Rock debris generated during under-excavation is then transported to the outside of the tunnel by trucks or other transportation methods.

[0005] Regarding the existing technologies mentioned above, tunnel under-excavation construction is cumbersome and it is not convenient to quickly remove the rock debris generated during the construction process, resulting in low work efficiency. Summary of the Invention

[0006] In order to facilitate under-excavation construction of tunnels and to facilitate the rapid removal of stone debris generated during construction, thereby improving construction efficiency, this application provides an automatic stone debris collection and transmission device for under-excavation tunnel construction.

[0007] The automatic collection and conveying device for rock debris in tunnel under-excavation treatment provided in this application adopts the following technical solution:

[0008] An automatic collection and conveying device for under-excavation treatment of rock debris in tunnels includes a mounting frame, a conveying mechanism, a rock drilling mechanism, and a motion mechanism. The conveying mechanism includes a conveying frame, a conveyor belt, and a conveying lifting assembly. The conveying lifting assembly is mounted on the mounting frame and drives the conveying frame to move vertically. The conveyor belt is mounted on the conveying frame and transports the rock debris. The rock drilling mechanism includes a fixed base, a rock drilling rod, and a driving assembly. The rock drilling rod passes through and slides into the fixed base. The driving assembly is mounted on the fixed base and drives the rock drilling rod to reciprocate. The motion mechanism includes an inner rod, an outer rod, a rotating assembly, and a telescopic assembly. The outer rod is coaxially sleeved on the inner rod. The rotating assembly is mounted on the conveying frame and drives the outer rod to rotate. The telescopic assembly is mounted on the outer rod and drives the inner rod to move along its own axis. The fixed base is mounted on the inner rod.

[0009] By adopting the above technical solution, during the tunnel under-excavation construction process, the rotation of the outer rod driven by the rotating component, combined with the movement of the inner rod along its own axis driven by the telescopic component, enables the fixed seat to quickly move the rock drill rod to the construction position. Subsequently, the reciprocating motion of the rock drill rod driven by the driving component realizes the rock drilling construction at the construction position. The rock debris generated during the construction process falls into the conveyor belt and is transported uniformly by the conveyor belt, which facilitates the rapid removal of the rock debris generated during the construction process. Moreover, during the tunnel under-excavation construction process, the fixed seat can be moved to the designated position and the construction can be carried out by the rock drill rod. There is no need for manual assistance with auxiliary rock drilling equipment for further tunnel construction. The operation is simple and conducive to improving work efficiency.

[0010] Optionally, the conveying and lifting assembly includes a conveying motor, a conveying screw, a conveying slide, an active connecting rod, and a driven connecting rod. The conveying slide is slidably fitted to the mounting frame. The conveying screw is horizontally rotatably mounted on the mounting frame. The conveying screw passes through and is threadedly fitted to the conveying slide. The conveying motor drives the conveying screw to rotate. The active and driven connecting rods are rotatably fitted. One end of the active connecting rod is rotatably fitted to the conveying slide and the other end is rotatably fitted to the conveying frame. One end of the driven connecting rod is rotatably fitted to the mounting frame and the other end is rotatably fitted to the driven slide. The driven slide is slidably fitted to the conveying frame.

[0011] By adopting the above technical solution, when the conveyor motor drives the conveyor screw to rotate, the conveyor slide bar slides along the length of the conveyor screw under the limiting action of the mounting frame, thereby driving the conveyor frame to move vertically up and down through the cooperation of the active connecting rod and the driven connecting rod, which is convenient and stable.

[0012] Optionally, the drive assembly includes a drive motor, a drive plate, a main drive rod, and a driven rod. The drive plate is rotatably mounted on a fixed base. The drive motor is mounted on the fixed base and used to rotate the drive plate. One end of the main drive rod is eccentrically mounted on the drive plate, and the other end is rotatably mounted on the driven rod. The driven rod is rotatably mounted on the fixed base. The free end of the driven rod away from the main drive rod has a driven groove extending along its own axis. A driven fixed rod is slidably fitted in the driven groove, and the driven fixed rod is fixedly mounted on the rock drill rod.

[0013] By adopting the above technical solution, when the drive motor drives the drive plate to rotate, the main drive rod drives the driven rod to swing back and forth, thereby causing the fixed rod to drive the rock drill rod to move back and forth, which facilitates the stable under-excavation construction of the tunnel by the rock drill rod.

[0014] Optionally, the rock drilling mechanism further includes a secondary chisel rod, which is arranged parallel to the rock drilling rod. The secondary chisel rod passes through and slides into the fixed seat. A secondary drive groove extending along its own axis is opened at the free end of the drive rod near the main drive rod. A secondary fixed rod slides in the secondary drive groove and is fixedly connected to the secondary chisel rod.

[0015] By adopting the above technical solution, during the rotation of the drive plate driven by the drive motor, the main drive rod drives the driven rod to reciprocate, and the auxiliary fixed rod simultaneously drives the auxiliary chisel rod to reciprocate synchronously. This facilitates the cyclic reciprocating motion of the auxiliary chisel rod and the rock drilling rod to further stabilize the under-excavation construction in the tunnel.

[0016] Optionally, the fixed seat is installed on the inner rod by a fixed installation mechanism, which includes a fixed frame, a first adjustment component, and a second adjustment component. The fixed frame is fixedly installed on one end of the inner rod. The first adjustment component is disposed on the fixed frame and is used to drive the fixed seat to rotate around its own axis. The second adjustment component is disposed on the fixed frame and is used to drive the fixed seat to rotate around the horizontal direction.

[0017] By adopting the above technical solution, the setting of the first adjustment component and the second adjustment component driving the fixed seat to rotate around their own axis and in the horizontal direction respectively makes it easy for the rock drill rod and the auxiliary drill rod to stably achieve under-excavation construction in the tunnel from more different construction angles while the position of the inner rod remains unchanged, which has strong applicability.

[0018] Optionally, the first adjustment component includes a first motor, a main bevel gear, and a driven bevel gear. The main bevel gear is rotatably mounted on a fixed frame. The first motor is mounted on the fixed frame and is used to drive the main bevel gear to rotate. The driven bevel gear is rotatably mounted on the fixed frame and coaxially fixedly connected to a fixed base. The driven bevel gear meshes with the main bevel gear.

[0019] By adopting the above technical solution, when the first motor drives the main bevel gear to rotate, the driven bevel gear drives the fixed seat to rotate around its own axis together. The cooperation between the main bevel gear and the driven bevel gear helps to ensure the stability of the fixed seat during the rotation adjustment process around its own axis.

[0020] Optionally, the fixed frame includes a fixed part and a rotating part. The fixed part is fixedly installed at one end of the inner rod. The main bevel gear is rotatably installed at the fixed part, and the driven bevel gear is rotatably installed at the rotating part. The second adjustment assembly includes a second motor and an adjustment shaft. The adjustment shaft is horizontally rotatably installed at the fixed part, and the rotating part is fixedly installed at the adjustment shaft. The adjustment shaft is coaxially inserted and rotatably engaged with the main bevel gear. The second motor is used to drive the adjustment shaft to rotate.

[0021] By adopting the above technical solution, when the second motor drives the adjusting shaft to rotate, the rotating part drives the main bevel gear and the fixed seat to rotate together around the axis of the adjusting shaft, that is, in the horizontal direction. The rotation of the fixed seat driven by the first motor and the second motor respectively facilitates the rock drill rod and the auxiliary drill rod to be adaptively adjusted to different tunnel under-excavation conditions. It has strong applicability and the first motor and the second motor have a high degree of integration, small installation volume, and strong installation applicability.

[0022] Optionally, a flexible protective cover is provided between the rotating part and the fixed part to enclose the first motor, the second motor, the main bevel gear, the driven bevel gear, and the adjusting shaft.

[0023] By adopting the above technical solution, the flexible protective cover can effectively protect the covered components while ensuring the rotational stability of the fixed base, thus achieving stable construction of tunnel under-excavation.

[0024] Optionally, the rotating assembly includes a fixed rotating shaft, a rotating worm gear, and a rotating worm. The fixed rotating shaft is horizontally fixedly installed on the outer rod and passes through and rotatably engages with the conveyor frame. The rotating worm gear is coaxially fixedly installed on the fixed rotating shaft, and the rotating worm is rotatably installed on the conveyor frame and meshes with the rotating worm gear.

[0025] By adopting the above technical solution, when the rotating worm is rotated, the rotating worm wheel drives the outer rod to rotate around the axis of the rotating shaft through the fixed rotating shaft. The self-locking effect between the rotating worm wheel and the rotating worm helps to fully ensure the stability of the position of the outer rod after rotation.

[0026] Optionally, the telescopic assembly includes a telescopic worm gear and a telescopic worm. The telescopic worm gear is coaxially and rotatably mounted on one end of the outer rod. The inner rod passes through and is threaded into the telescopic worm gear. The outer rod is fixedly connected to a limit slider. The inner rod has a limit groove extending along its own length. The limit slider slides and engages in the limit groove. The telescopic worm is rotatably mounted on the outer rod and meshes with the telescopic worm gear.

[0027] By adopting the above technical solution, when the telescopic worm is rotated, the telescopic worm wheel rotates together. The inner rod moves along its own axis due to the threaded engagement with the telescopic worm wheel and the limiting action of the limiting slider and the limiting groove. The self-locking effect between the telescopic worm wheel and the telescopic worm helps to fully ensure the stability of the position of the inner rod after movement.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. During the under-excavation of the tunnel, the rock debris generated falls into the conveyor and is transported in a unified manner, which facilitates the rapid removal of the rock debris generated during the construction process. During the under-excavation of the tunnel, the fixed base can be moved to the designated position and construction can be carried out by drilling rod. There is no need for manual assistance with auxiliary drilling equipment to further construct the tunnel. The operation is simple and helps to improve work efficiency.

[0030] 2. During the rotation of the drive plate driven by the drive motor, the main drive rod drives the driven rod to reciprocate, and the auxiliary fixed rod simultaneously drives the auxiliary chisel rod to reciprocate synchronously. This facilitates the cyclic reciprocating motion of the auxiliary chisel rod and the rock drilling rod, further stabilizing the under-excavation construction in the tunnel.

[0031] 3. The rotation of the fixed base is driven by the first motor and the second motor respectively, which facilitates the adaptive adjustment of the rock drill rod and the auxiliary drill rod to different tunnel under-excavation conditions. It has strong applicability and the first motor and the second motor have a high degree of integration, small installation volume, and strong installation applicability. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0041] This application discloses an automatic collection and conveying device for rock debris in tunnel under-excavation treatment. (Refer to...) Figure 1 and Figure 2 The automatic collection and transmission device for under-excavation treatment of rock debris in tunnels includes a mounting frame 1, a conveying mechanism, a rock drilling mechanism, and a motion mechanism. In this embodiment, the mounting frame 1 is a rectangular plate. The length direction of the mounting frame 1 is the x-axis direction, the width direction is the y-axis direction, and the thickness direction, i.e., the vertical direction, is the z-axis direction.

[0042] Reference Figure 1 The conveying mechanism includes a conveying frame 2, a conveyor belt 3, and a conveying lifting assembly. Specifically, the conveying lifting assembly includes a conveying motor 4, a conveying screw 5, a conveying slide bar 6, an active connecting rod 7, and a driven connecting rod 8. The two ends of the conveying slide bar 6 are fixedly connected to conveying sliders 9. The top of the mounting frame 1 is provided with two conveying grooves 10 extending along the x-axis. The two conveying sliders 9 slide and engage in the two conveying grooves 10 respectively, so that the conveying slide bar 6 slides and engages in the mounting frame 1 along the x-axis.

[0043] Reference Figure 1 and Figure 2A conveying screw 5 is horizontally mounted on the mounting frame 1. The conveying screw 5 passes through the x-axis and is threaded into the conveying slide rod 6. A conveying motor 4 is mounted on the mounting frame 1 and drives the conveying screw 5 to rotate. The driving connecting rod 7 and the driven connecting rod 8 are rotatably connected at their midpoints via a rotating shaft. One end of the driving connecting rod 7 is rotatably connected to the conveying slide rod 6, and the other end is rotatably connected to the conveying frame 2. One end of the driven connecting rod 8 is rotatably connected to the mounting frame 1, and the other end is rotatably connected to the driven slide rod 11. Both ends of the driven slide rod 11 are fixedly connected to driven sliders 12. Two driven grooves 13 extending along the x-axis are provided at the bottom of the conveying frame 2. The two driven sliders 12 slide and engage within the two driven grooves 13, allowing the driven slide rod 11 to slide and engage with the driven frame along the x-axis.

[0044] Continue to refer to Figure 2 and Figure 3 When the conveyor motor 4 drives the conveyor screw 5 to rotate, the conveyor slide rod 6 slides along the length of the conveyor screw 5, thereby driving the conveyor frame 2 to perform stable vertical lifting and lowering motion through the cooperation of the active connecting rod 7 and the driven connecting rod 8. The conveyor belt 3 is horizontally arranged on the conveyor frame 2 along the x-axis to realize the centralized transportation of stone debris generated during the tunnel under-excavation construction. Furthermore, during the tunnel under-excavation construction, a collection bucket 45 can be placed on one side of the conveyor belt 3 in the output direction to collect stone debris.

[0045] Refer to 1 and Figure 4 The rock drilling mechanism includes a fixed base 14, a rock drilling rod 15, a secondary rock drilling rod 16, and a drive assembly. The fixed base 14 is rectangular and box-shaped. The rock drilling rod 15 and the secondary rock drilling rod 16 are both located inside the fixed base 14 and arranged in parallel. One end of the rock drilling rod 15 and the secondary rock drilling rod 16 passes through the fixed base 14 and slides in cooperation with the fixed base 14. The drive assembly is located inside the fixed base 14 and includes a drive motor 17, a drive rotating plate 18, a main drive rod 19, and a driven rod 20. The drive rotating plate 18 is rotatably mounted on the fixed base 14 and is circular in shape. The drive motor 17 is fixedly mounted on the fixed base 14 and is used to rotate the drive plate around its own axis.

[0046] Reference Figure 3 and Figure 4One end of the main drive rod 19 is eccentrically mounted to the drive plate 18, and the other end is rotatably mounted to the driven rod 20. The driven rod 20 is rotatably mounted to the fixed base 14 via a pivot located near the center of its length. A driven groove 21 extending along its own axis is formed at the free end of the driven rod 20 away from the main drive rod 19. A driven fixed rod 22 is slidably fitted within the driven groove 21 and is fixedly mounted to the rock drill rod 15. A secondary drive groove 23 extending along its own axis is formed at the free end of the driven rod 20 near the main drive rod 19. A secondary fixed rod 24 is slidably fitted within the secondary drive groove 23 and is fixedly connected to the secondary drill rod 16. This allows the main drive rod 19 to drive the driven rod 20 to reciprocate when the drive motor 17 rotates the drive plate 18, thereby causing the rock drill rod 15 and the secondary drill rod 16 to perform cyclic reciprocating motion, thus facilitating stable under-excavation construction of the tunnel inner wall.

[0047] Reference Figure 3 and Figure 5 The motion mechanism includes an inner rod 25, an outer rod 26, a rotating assembly, and a telescopic assembly. The outer rod 26 is coaxially sleeved and slidably fitted onto the inner rod 25. The rotating assembly is mounted on the conveyor frame 2 and drives the outer rod 26 to rotate. Specifically, the rotating assembly includes a fixed shaft 27, a rotating worm gear 28, and a rotating worm 29. The fixed shaft 27 is horizontally fixedly installed on the outer rod 26. The conveyor frame 2 includes a portal frame 201. The fixed shaft 27 passes through and rotatably fits onto the conveyor frame 2. The rotating worm gear 28 is coaxially fixedly installed on the fixed shaft 27. The rotating worm 29 is rotatably installed on the conveyor frame 2 and meshes with the rotating worm gear 28, so that when the rotating worm 29 rotates, the rotating worm gear 28 drives the outer rod 26 to rotate around its own axis via the fixed shaft 27. To facilitate applying force to rotate the rotating worm 29, a rotating handle 30 is fixedly connected to one end of the rotating worm 29.

[0048] Reference Figure 5 and Figure 6 The telescopic assembly includes a telescopic worm gear 31 and a telescopic worm 32. The telescopic worm gear 31 is coaxially and rotatably mounted on one end of the outer rod 26. The inner rod 25 passes through and is threadedly engaged with the telescopic worm gear 31. A limiting slider 33 is fixedly connected inside the outer rod 26. The inner rod 25 has a limiting groove 34 extending along its own length. The limiting slider 33 slides within the limiting groove 34. The telescopic worm 32 is rotatably mounted on the outer rod 26 and meshes with the telescopic worm gear 31, so that when the telescopic worm 32 rotates, the telescopic worm gear 31 rotates together. The inner rod 25 moves along its own axis due to the threaded engagement with the telescopic worm gear 31 and the limiting action of the limiting slider 33 and the limiting groove 34, thus realizing the telescopic movement of the inner rod 25 within the outer rod 26. To facilitate the application of force to rotate the telescopic worm 32, a telescopic handle 35 is fixedly connected to one end of the telescopic worm 32.

[0049] Reference Figure 3 and Figure 4 The fixed seat 14 is installed on one end of the inner rod 25 through a fixed installation mechanism. The fixed seat 14 and the telescopic worm gear 31 are located at both ends of the outer tube, respectively. Specifically, the fixed installation mechanism includes a fixed frame 36, a first adjustment component and a second adjustment component. The fixed frame 36 includes a fixed part 361 and a rotating part 362. The fixed part 361 is fixedly installed on the end of the inner rod 25. The fixed seat 14 is coaxially fixedly connected to a fixed shaft 37. The fixed shaft 37 passes through and rotates with the rotating part 362.

[0050] Reference Figure 4 The first adjustment assembly is used to drive the fixed base 14 to rotate around its own axis. Further, the first adjustment assembly includes a first motor 38, a main bevel gear 39, and a driven bevel gear 40. The main bevel gear 39 is arranged along the y-axis and rotatably mounted on the fixed part 361 of the fixed frame 36. The first motor 38 is fixedly mounted on the fixed frame 36 and used to drive the main bevel gear 39 to rotate around its own axis. The driven bevel gear 40 is coaxially fixedly connected to the fixed shaft 37 and rotatably mounted on the rotating part 362 of the fixed frame 36, meshing with the main bevel gear 39. This allows the driven bevel gear 40 to drive the rotating part 362 to rotate together around the axis of the driven bevel gear 40, i.e., the fixed base 14, when the first motor 38 drives the main bevel gear 39 to rotate.

[0051] Continue to refer to Figure 4 The second adjustment component, a fixed frame 36, is used to drive the fixed base 14 to rotate horizontally. Further, the second adjustment component includes a second motor 41 and an adjustment shaft 42. The adjustment shaft 42 is positioned along the y-axis and horizontally rotatably mounted on the fixed part 361. The second motor 41 is mounted on the fixed part 361 and drives the adjustment shaft 42 to rotate. Two rotating connecting plates 43 are integrally fixedly connected to the rotating part 362, and both rotating connecting plates 43 are fixedly connected to the adjustment shaft 42. The adjustment shaft 42 is coaxially inserted and rotatably engaged with the main bevel gear 39, so that when the second motor 41 drives the adjustment shaft 42 to rotate, the rotating part 362 drives the main bevel gear 39 and the fixed base 14 to rotate together around the axis of the adjustment shaft 42, i.e., horizontally. By driving the fixed base 14 to rotate via the first motor 38 and the second motor 41, the rock drill rod 15 and the auxiliary drill rod 16 can stably achieve under-excavation construction within the tunnel from more different construction angles, provided that their positions remain unchanged after the inner rod 25 is adjusted.

[0052] Reference Figure 1 and Figure 4A flexible protective cover 44 is fixedly provided on the side opposite to the rotating part 362 and the fixed part 361, which covers the first motor 38, the second motor 41, the main bevel gear 39, the driven bevel gear 40 and the adjusting shaft 42. In this embodiment, the flexible protective cover 44 is selected as a bellows cover to achieve stable protection for the first motor 38, the second motor 41, the main bevel gear 39, the driven bevel gear 40 and the adjusting shaft 42. At the same time, it is convenient to further ensure the driving stability of the first motor 38 and the second motor 41 while ensuring the rotational stability of the fixed base 14.

[0053] The implementation principle of the automatic collection and transmission device for under-excavation tunnel construction according to this application is as follows: During the under-excavation construction of the tunnel, the rotation of the outer rod 26 is driven by the rotation of the worm gear 29, which in turn drives the inner rod 25 to move along its own axis. This causes the fixed seat 14 to move the rock drill rod 15 quickly to the construction position. Then, the rock drill rod 15 and the auxiliary drill rod 16 are driven by the drive motor 17 to perform the reciprocating motion to realize the rock drilling construction at the construction position. The rock debris generated during the construction process falls into the conveyor belt 3 and is transported uniformly by the conveyor belt 3, which facilitates the rapid removal of the rock debris generated during the construction process. In addition, during the under-excavation construction of the tunnel, the fixed seat 14 can be moved to the designated position and the construction can be carried out by the rock drill rod 15. There is no need for manual assistance with auxiliary rock drilling equipment to further construct the tunnel. The operation is simple and conducive to improving work efficiency.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
