Description

Technical Field

[0001] The present invention relates to the technical field of tunnels, and in particular to a tunnel drilling device and a drilling method. Background Art

[0002] With the continuous construction of railway tunnels in my country, many installation holes need to be drilled on the tunnel wall for cable installation, arch support, and disease control.

[0003] Traditional drilling operations often require the installation of scaffolding, manual determination of drilling locations, and then drilling. This is a complex and labor-intensive process. Multiple workers working simultaneously on the scaffolding also pose the risk of falling from the platform. The flying concrete dust during drilling can also affect workers' health and pollute the environment.

[0046] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0047] Example 1

[0048] like Figure 1-2 As shown, this embodiment provides a tunnel drilling device comprising a drilling mechanism 1, a propulsion mechanism 2, a drive mechanism 3, and a chassis mechanism 6. The drilling mechanism 1 is used to drill holes in the tunnel wall and includes a positioning assembly 11. The positioning assembly 11 is located on the side close to the tunnel wall for contact with the tunnel wall. The drilling mechanism 1 is connected to the propulsion mechanism 2, which is used to drive the drilling mechanism 1 in linear motion so that the drilling mechanism 1 is in continuous contact with the tunnel wall. The propulsion mechanism 2 is rotationally connected to the drive mechanism 3. The drive mechanism 3 is used to drive the drilling mechanism 1 on the propulsion mechanism 2 in rotation to initially position the drilling mechanism 1 and to drive the drilling mechanism in linear motion so that the positioning assembly 11 on the drilling mechanism 1 is perpendicular to the tunnel wall. It should be noted that the tunnel wall is not a vertical plane, and the drilling mechanism 1 needs to be vertically positioned for accurate drilling.

[0049] A tunnel drilling device provided in this embodiment realizes automatic drilling of the tunnel wall due to the provision of a drilling mechanism 1, a propulsion mechanism 2 and a driving mechanism 3, thereby avoiding the high labor intensity and the risk of falling off the platform in manual drilling, and has high operating efficiency and a simple structure. At the same time, since a positioning component 11 is provided on the drilling mechanism 1, and the driving mechanism 3 drives the drilling mechanism 1 to rotate through the propulsion mechanism 2 to initially position the drilling mechanism 1, the driving mechanism 3 drives the drilling mechanism 1 to move linearly through the propulsion mechanism 2. At this time, the propulsion mechanism 2 connected to the drilling mechanism 1 rotates relative to the driving mechanism 3 so that the two positioning points of the positioning component 11 on the drilling mechanism 1 are fully in contact with the tunnel wall to complete vertical positioning, so that the drilling mechanism 1 can be quickly positioned, further improving the operating efficiency of the drilling device.

[0050] like Figure 3As shown, the drilling mechanism 1 also includes a support frame 12, a plurality of drilling units 13, and a plurality of dust cover assemblies 14. The plurality of drilling units 13 are mounted on the support frame 12. The positioning assembly 11 is connected to the support frame 12 and is located on a side close to the tunnel wall. Specifically, the positioning assembly 11 includes a plurality of vertical positioning rods 111, which are fixedly connected to the support frame 12 at intervals.

[0051] Specifically, the support frame 12 includes a horizontal connecting beam 121, multiple mounting beams 122 and a mounting rod 124. The mounting rod 124 and the multiple mounting beams 122 are arranged at intervals along the length direction of the horizontal connecting beam 121. To facilitate the installation of the mounting beam 122, the mounting beam 122 is connected to the horizontal connecting beam 121 through a connecting cross beam 123. The mounting rod 124 is used to connect to the propulsion mechanism 2. Multiple drilling units 13 are arranged one-to-one on multiple mounting beams 122. Multiple vertical positioning rods 111 are arranged at intervals along the length direction of the horizontal connecting beam 121. The mounting beam 122 and the vertical positioning rod 111 are arranged on opposite sides of the horizontal connecting beam 121, and the middle part of the vertical positioning rod 111 is connected to the horizontal connecting beam 121.

[0052] like Figure 1 As shown, the dust cover assembly 14 is provided in a one-to-one correspondence with the drilling unit 13 and is provided at the drill bit of the drilling unit 13. The dust cover assembly 14 includes a dust cover body 141, a vacuum generator 142 and an air pipe 143. The dust cover body 141 is sleeved on the drill bit of the drilling unit 13. The connecting pipe on the dust cover body 141 is connected to the vacuum generator 142, and the air extraction end of the vacuum generator 142 is connected to the air pipe 143. When in use, the vacuum generator 142 operates to extract dust generated by drilling by the drilling unit 13 in the dust cover body 141.

[0053] like Figure 4 As shown, the propulsion mechanism 2 includes a propulsion bracket 21, a telescopic drive 22 and two groups of sliding assemblies 23. The propulsion bracket 21 is provided with a hinge seat 26. One end of the telescopic drive 22 is hinged to the hinge seat 26. The other end of the telescopic drive 22 is detachably connected to the horizontal connecting beam 121 through a connecting head 25. The two groups of sliding assemblies 23 are respectively connected to both sides of the propulsion bracket 21. The sliding assembly 23 includes a guide rail 231 and a slider 232 slidably connected to the guide rail 231. The guide rails 231 in the two groups of sliding assemblies 23 are arranged on both sides of the propulsion bracket 21. The slider 232 is fixedly connected to the mounting rod 124 on the support frame 12. When the telescopic drive 22 is extended, the moving end of the telescopic drive 22 drives the horizontal connecting beam 121 to move, and the mounting rod 124 on the slider 232 slides relative to the guide rail 231. In this embodiment, by providing the sliding assembly 23, the smooth operation of the drilling mechanism 1 with a larger overall structure can be ensured.

[0054] like Figure 5 As shown, the driving mechanism 3 includes a cantilever connecting rod 31, a telescopic assembly 32, and a rotating assembly 33. The propulsion mechanism 2 is rotatably connected to the cantilever connecting rod 31 via a connecting block 24, and the bottom end of the propulsion mechanism 2 is fixedly connected to the connecting block 24. The movable end of the telescopic assembly 32 is connected to the cantilever connecting rod 31 to drive the cantilever connecting rod 31 to move linearly, and the rotating assembly 33 is connected to the cantilever connecting rod 31 to drive the cantilever connecting rod 31 to rotate. As a result, the driving mechanism 3 can drive the drilling mechanism 1 thereon to rotate and move linearly through the propulsion mechanism 2, thereby achieving initial positioning and vertical positioning of the drilling mechanism 1.

[0055] Specifically, the rotating assembly 33 includes two rotating units 331 arranged opposite to each other, each rotating unit 331 includes a rotating arm 3311 and a rotating base 3312 rotatably connected to the rotating arm 3311, and the two ends of the cantilever link 31 are respectively slidingly connected to the rotating arms 3311 in the two rotating units 331, wherein a rotating base 3312 in one of the two rotating units 331 is provided with a rotary drive to drive the rotating arm 3311 to rotate around the rotating base 3312, and the rotating arm 3311 on the other side is driven to rotate through the cantilever link 31.

[0056] Among them, the telescopic assembly 32 includes a telescopic body 321 and two telescopic fixed seats 322 arranged opposite to each other. The telescopic fixed seats 322 are arranged on the chassis mechanism 6. A rotating link 323 is rotatably connected to the two telescopic fixed seats 322. The fixed end of the telescopic body 321 is fixed on the rotating link 323. The movable end of the telescopic body 321 is connected to the cantilever link 31 and then pushes the propulsion mechanism 2 on the cantilever link 31 to move linearly so that the vertical positioning rod 111 of the drilling mechanism 1 on the propulsion mechanism 2 abuts against the tunnel wall.

[0057] During actual application, when one end of the vertical positioning rod 111 abuts against the tunnel wall, the telescopic body 321 is further pushed forward, and the connecting block 24 on the propulsion mechanism 2 rotates around the cantilever connecting rod 31 to make the other end of the vertical positioning rod 111 also abut against the tunnel wall. At this time, the vertical positioning rod 111 is positioned vertically to the tunnel wall. In this embodiment, the automatic positioning of the drilling mechanism 1 can be achieved only through the cooperation of the vertical positioning rod 111 and the telescopic component 32 in the driving mechanism 3, which is easy to operate and improves working efficiency.

[0058] The operating process of the drive mechanism 3 is as follows: when initially positioning the drilling mechanism 1, the rotary driver drives the rotating arm 3311 to rotate, thereby driving the propulsion mechanism 2 on the cantilever link 31 to rotate and adjust the angle of the drilling mechanism 1 thereon. To make the operation of the drive mechanism 3 more flexible, the rotary unit also includes a cantilever 3313. The cantilever 3313 is arranged on one side of the rotating arm 3311 and slides along the length of the rotating arm 3311. The two ends of the cantilever link 31 are respectively connected to the cantilever 3313 within the rotating arm 3311. The movable end of the telescopic body 321 drives the cantilever link 31 to move, causing the cantilever 3313 to extend and retract along the rotating arm 3311, thereby achieving the linkage between rotation and linear movement in the drive mechanism 3.

[0059] In actual use, the tunnel boring device also includes an adjustment member 4, which is used to adjust the preload force between the contact surfaces of the propulsion mechanism 2 and the drive mechanism 3. The adjustment member 4 is a set screw threadedly connected to the connecting block 24. The movable end of the set screw abuts the cantilever link 31. The preload force between the connecting block 24 and the cantilever link 31 is adjusted by rotating the set screw. It should be noted that the preload force between the connecting block 24 and the cantilever link 31 should be greater than the weight of the propulsion mechanism 2 and the drilling mechanism 1 to prevent the propulsion mechanism 2 from causing the drilling mechanism 1 to slide around the cantilever link 31 in the absence of external force.

[0060] like Figure 1 As shown, to improve the stability of the drilling mechanism 1 during drilling operations and prevent deviation of the drilled hole, the tunnel drilling apparatus further includes a support assembly 5. The support assembly 5 comprises a support rod 51, two telescopic sleeves 52 arranged opposite each other, and a locking unit 53. The support rod 51 passes through the propulsion bracket 21, and both ends of the support rod 51 are rotatably connected to the movable ends of the telescopic sleeves 52. The fixed end of the telescopic sleeves 52 is connected to the rotating unit 331.

[0061] like Figure 6-Figure 7 As shown, the telescopic sleeve 52 includes a fixed rod 521 and a movable rod 522 arranged in the fixed rod 521. The movable rod 522 is slidably connected along the length direction of the fixed rod 521. One end of the fixed rod 521 is connected to the connecting plate 3314 on the rotating seat 3312 in the rotating unit 331.

[0062] Specifically, the movable rod 522 is provided with a plurality of positioning slots 5221 along its length. The locking unit 53 includes a locking seat 531, a spring 532, a nut 533, and a spring catch 534. The locking seat 531 is disposed at one end of the outer wall of the fixed rod 521. The spring 532 is disposed within the locking seat 531. The top end of the spring 532 is connected to the nut 533, and the bottom end of the spring 532 is connected to the spring catch 534. The nut 533 is threadedly connected to the top end of the locking seat 531. The spring catch 534 extends into the positioning slot 5221 of the movable rod 522 to limit the movable rod 522. The bottom end of the nut 533 abuts against the top end of the spring 532 to adjust the compression force of the spring 532 and thereby adjust the pressure of the spring 532 on the spring catch 534. When the telescopic assembly 32 drives the propulsion mechanism 2 to move forward, the propulsion mechanism 2 drives the movable rod 522 to move forward through the support rod 51, and then the support assembly 5 can automatically adjust with the propulsion mechanism 2, and by setting the locking unit 53, the movable rod 522 is prevented from retreating, thereby ensuring the stability of the drilling operation of the drilling unit 13.

[0063] like Figure 5 As shown, the chassis mechanism 6 includes a chassis body 61, rope fixing bases 62, and universal wheels 63. The universal wheels 63 are located at the four lower corners of the chassis body 61 to facilitate movement and transportation of the tunnel boring device. The rope fixing bases 62 are located at the four upper corners to facilitate hoisting of the tunnel boring device. The rotating base 3312 and telescopic fixing base 322 of the drive mechanism 3 are both located on the chassis body 61 of the chassis mechanism 6.
