[0025] In combination with Figure 5 , the walking mechanism 3 is distributed at the bottom of both ends of the tunneling machine, includes the walking frame 31, the walking track 32 and the ground gripping device 33, can drive the drilling mechanism 1, the support and mesh laying mechanism 2 and the manual operation platform 4 to move synchronously, so as to improve the stability of the tunneling machine, and can also be positioned synchronously, so as to improve the reliability of the roadway tunneling.

[0026] Specifically, the walking track 32 is arranged in the walking frame 31, the ground gripping device 33 is arranged at both ends of the walking track 32 and is connected with the walking frame 31 through the ground gripping lifting device 34, so that the walking track 32 can drive the tunneling machine to move stably on the rugged ground of the roadway to the working position of the roadway, the ground gripping lifting device 34 can drive the ground gripping device 33 to move towards the ground of the roadway and be fixed with the ground, so as to position the tunneling machine and ensure the stability and reliability of the tunneling work.

[0027] Here, the ground gripping device 33 and the ground gripping lifting device 34 are conventional technical means in the field, as an example, the ground gripping lifting device 34 can be composed of the existing hydraulic support column, and the ground gripping device 33 can be composed of the existing shoe plate, so that the ground gripping lifting device 34 can be pressed on the ground together with the ground gripping device 33 to position the tunneling machine through the static friction.

[0028] In combination with Figure 4 , Figure 6 and Figure 7 , further, the manual operation platform 4 is arranged inside the walking mechanism 3, can move along the axial and height directions of the roadway, and is convenient for the standing of the workers and the control of the working states of the drilling mechanism 1, the support and mesh laying mechanism 2 and the walking mechanism 3.

[0029] The man-operated platform 4 comprises an operating telescopic device 41, a standing platform 42, an operating lifting device 43 and a control device 44. The operating telescopic device 41 is horizontally distributed and arranged inside the walking frame 31 of the walking mechanism 3 through operating fasteners 45. The operating telescopic device 41 is connected with the vertically distributed operating lifting device 43 at the end thereof. The standing platform 42 is arranged at the end region of the operating telescopic device 41 and cooperates with the operating lifting device 43. The control device 44 is arranged at the top end of the operating lifting device 43. The operating personnel can stand on the standing platform 42 and control the working states of the drilling mechanism 1, the support and net laying mechanism 2 and the walking mechanism 3 through the control device 44.

[0030] Further, the operating telescopic device 42 and the operating lifting device 43 are composed of hydraulic telescopic rods. The operating lifting device 43 can drive the control device 44 to move along the height direction of the roadway so as to adapt to the height of the operating personnel. The operating telescopic device 42 can drive the man-operated platform 4 to move along the axial direction of the roadway so as to adjust the position of the man-operated platform 4, prevent the man-operated platform 4 from interfering with the tunneling operation and ensure the safety of the operating personnel. Meanwhile, the operating personnel can conveniently observe the tunneling operation state.

[0031] Here, the control device 44 is a conventional technical means in the art. For example, the control device 44 can be composed of an existing control cabinet and a control device and is connected with the drilling mechanism 1, the support and net laying mechanism 2 and the walking mechanism 3, respectively. The operating personnel can control the working states of the tunneling machine through the control device 44.

[0032] In combination Figures 2 to 4 Further, the support and net laying mechanism 2 is arranged on the walking mechanism 3 and comprises the support and net laying mechanism 2 arranged on the both sides of the tunneling machine body 5 and the support and net laying mechanism 22 arranged on the top thereof. The support and net laying mechanism 2 can support the two sides and the top surface of the roadway so as to ensure the stability of the tunneling machine.

[0033] In combination Figure 7 Specifically, the support and net laying mechanism 22 comprises a support and net laying frame 221, a support and net laying lifting device 222 and a top surface support body 223. The support and net laying lifting device 222 is composed of hydraulic telescopic support rods and is arranged at the both ends of the top of the walking frame 31 of the walking mechanism 3, respectively. The support and net laying frame 221 is horizontally distributed and connected with the end of the support and net laying lifting device 222. The support and net laying lifting device 222 can drive the support and net laying frame 221 to move along the height direction of the roadway so as to adapt to the roadway of different heights.

[0034] Further, the support and net laying frame 221 and the support and net laying lifting device 222 are detachably connected. When the width of the support and net laying mechanism 21 is adjusted subsequently, the support and net laying frame 221 can be detached from the support and net laying lifting device 222 and a support and net laying frame 221 corresponding to the width is reinstalled so as to adapt to the width of the support and net laying mechanism 21.

[0035] Further, the top surface support body 223 is arranged in an array on the top support frame 221 to support the roadway top surface and ensure the overall stability of the roadheader.

[0036] In combination Figures 7 to 9 In combination, the support side assembly 21 includes a first support side assembly 2101 and a second support side assembly 2102 arranged on opposite sides of the support top assembly 22. Take one of the support side assemblies 21 as an example.

[0037] The support side assembly 21 includes a support side support rod 211, a support side frame 212, a support side rotating device 213, a side support body 214, and a support side mounting bracket 215. The support side support rod 211 is arranged at the bottom of the support top frame 222, and the support side mounting bracket 215 is arranged vertically, with one end connected to the fixed end of the support top lifting device 222 of the support top assembly 22 and the other end connected to the support side support rod 211, so that the support side support rod 211 is stably connected to the support top lifting device 222. When the support top lifting device 222 moves the support top assembly 22 in the height direction, the support side support rod 211 is placed at the bottom of the support top frame 222, which does not affect the stable movement of the support top assembly 22. At the same time, the support side mounting bracket 215 is arranged at the fixed end of the support top lifting device 222, which can ensure that the height of the support side assembly 21 remains unchanged and stably supports the two sides of the roadway.

[0038] Further, the end of the support side support rod 211 close to the outside of the support top assembly 22 is connected to the support side rotating device 213. The support side rotating device 213 includes a lateral telescopic rod 2131 and an inclined telescopic rod 2132, which are arranged at an angle and connected to the support side frame 212, respectively. The lateral telescopic rod 2131 is arranged inside the support side support rod 211 and connected to a push-pull oil cylinder inside the support side support rod 211, so that the push-pull oil cylinder can drive the lateral telescopic rod 2131 to extend or retract, thereby driving the support side frame 212 to move in the width direction of the roadway and stably supporting the two sides of the roadway.

[0039] In combination Figure 4 Preferably, a detachable reinforcing cross beam 25 is arranged between the outside of the walking mechanism 3 and the support side frame 212. The reinforcing cross beam 25 can be adjusted adaptively according to the moving distance of the support side frame 212 and the width of the roadway to ensure the stability of the support side frame 212 and effectively support the two sides of the roadway.

[0040] In combination Figure 7 At the same time, the inclined telescopic rod 2132 and the lateral telescopic rod 2131 are arranged in a triangular shape with the support side frame 212, which can ensure the stability and balance of the support side frame 212. The extension and retraction of the inclined telescopic rod 2132 can drive the support side frame 212 to rotate synchronously, so as to fine-tune the angle of the support side frame 212 and ensure that the support side frame 212 can adapt to the angle of the two sides of the roadway.

[0041] The side support bodies 214 are arranged in an array on the side support frame 212 and can support the two sides of the roadway.

[0042] In combination Figure 10 In order to ensure that the side support assembly 21 can adapt to roadways of different widths, the first side support assembly 2101 and the second side support assembly 2102 distributed on the two sides of the roof support assembly 22 are connected through the width adjustment device 23, and the width adjustment device 23 can adjust the spacing of the first side support assembly 2101 and the second side support assembly 2102, thereby ensuring effective support of the two sides of the roadway of different widths.

[0043] Specifically, the width adjustment device 23 includes a connecting sleeve 231, and the first side support rod of the first side support assembly 2301 and the second side support rod of the second side support assembly 2302 are respectively embedded in the connecting sleeve 231, and the first side support assembly 2301 and the second side support assembly 2302 are connected through the connecting sleeve 23.

[0044] Further, a plurality of connecting holes 232 are distributed along the length direction of the connecting sleeve 231, and the distribution spacing of the first side support assembly 2301 and the second side support assembly 2302 can be adjusted by adjusting the connecting holes 232, so that the first side support assembly 2301 and the second side support assembly 2302 are respectively moved along the width direction of the roadway, thereby adjusting the overall width of the side support assembly 21, so that the side support assembly 21 can adapt to roadways of different widths, and the first side support assembly 2301 and the second side support assembly 2302 support the two sides of the roadway.

[0045] Moreover, while adjusting the overall width of the side support assembly 21, the side support rod 211 of the side support assembly 21 will drive the roof lifting device 222 of the roof support assembly 22 to move synchronously along the width direction of the roadway, and the walking mechanism 3 is driven synchronously by the walking frame 31 to adjust the spacing between the two walking mechanisms 3, thereby adjusting the overall width of the roadheader, which can adapt to roadways of different widths.

[0046] Here, before adjusting the overall width of the side support assembly 21 and the roadheader, the roof support frame 221 is detached from the roof lifting device 222, so that the side support assembly 21 can be smoothly adjusted in width, and after the adjustment is completed, the roof support frame 221 of the corresponding width is installed on the roof lifting device 222, thereby ensuring the stability of the roadheader and supporting the top and two sides of the roadway.

[0047] In this way, the side support assembly 21 and the roof support assembly 22 support the two sides and the top of the roadway, respectively, to ensure the stability of the roadheader.

[0048] To improve the support stability of the side support assembly 21 and the top support assembly 22, the top support body 223 of the side support assembly 21 and the side support body 214 of the top support assembly 22 are respectively configured with adjustable angles, so that the top support body 223 and the side support body 214 can effectively contact the uneven roadway surface.

[0049] Combination Figure 7 and Figure 9 Specifically, the top support 223 and the side support 214 are connected to the top support frame 221 and the side support frame 212 respectively by flexible support members 24. When the top support 223 and the side support 214 come into contact with the roadway surface, they can adjust their angles by the flexible support members 24 under the action of the contact force, so as to effectively contact the uneven roadway surface and ensure that the side support assembly 21 and the top support assembly 22 provide stable support for the roadway.

[0050] Here, the flexible support 24 can be made of existing rubber blocks.

[0051] Combination Figure 11 Furthermore, the top support 223 and the side support 214 are equipped with magnets, which enable the top support 223 and the side support 214 to be connected to the metal mesh by magnetic attraction, so that the mesh can be laid on the top and sides of the roadway, thereby realizing the mesh laying and facilitating the fixed connection of the mesh on the top and sides, as well as subsequent anchor bolt support operations, thereby improving the efficiency of tunneling operations.

[0052] The supporting mesh laying mechanism 2 thus forms a support for the top surface of both sides of the tunnel and lays the mesh. In conjunction with this, the traveling mechanism 3 supports and fixes the tunnel ground through the gripping device 33, which can effectively ensure the stability of the tunneling machine, thereby improving the efficiency and reliability of tunneling operations.

[0053] Combination Figure 2 The tunneling machine also includes a drilling mechanism 1, which is distributed on the tunneling end face of the tunneling machine body 5. It can simultaneously drill holes in the outline of the tunneling face to improve tunneling efficiency.

[0054] Combination Figure 12 Specifically, the drilling mechanism 1 includes a drilling support 11 and a water-powered drilling rig 12. The drilling support 11 is respectively installed at the ends of the top support frame 221 and the side support frame 212. The water-powered drilling rig 12 is installed on the drilling support 11 by fasteners and is distributed along the periphery outline of the tunneling face, as well as in the middle area of ​​the tunneling face. This allows several water-powered drilling rigs 12 to simultaneously drill holes in the periphery outline and the middle area of ​​the tunneling face, separating the periphery of the tunneling face from the overall rock to form a free face. A pre-splitting hole is formed in the middle of the tunneling face. A splitting rod is inserted into the pre-splitting hole to break the rock and remove the fallen rock, thus completing one cycle of rock removal construction, which can effectively improve tunneling efficiency.

[0055] Here, the drilling support 11 is detachably connected to the top support frame 221 and the side support frame 212, facilitating the replacement of the drilling support 11 and adapting to tunneling machines and roadways of different widths. Furthermore, the distribution structure of the drilling support 11 and the water-jet drilling rig 12 can be adaptively adjusted according to specific applications. In this example, the drilling support 11 and the water-jet drilling rig 12 are directionally distributed. In some embodiments, the drilling support 11 and the water-jet drilling rig 12 can also be arranged in an arched or circular shape, such as... Figure 13 and Figure 14 To adapt to different tunneling needs.

[0056] Combination Figure 15 Furthermore, the drilling support 11 is also provided with an angle adjustment shim 13. In this example, the angle adjustment shim 13 is wedge-shaped and detachably mounted on the drilling support 11, so that the water-grinding drill 12 is mounted on the angle adjustment shim 13, and the distribution angle of the water-grinding drill 12 is adjusted to adjust the perimeter outline of the tunneling face.

[0057] Combination Figure 4 and Figure 16 To improve tunneling efficiency, this tunneling machine also includes an anchor bolting mechanism 6, which is located at the bottom of the support frame 221. The anchor bolting mechanism 6 includes an anchor bolt telescopic device 61 located at the bottom of the side support rod 211, and its end is connected to the hydraulic drilling rig 63 through an anchor bolt rotating device 62. This allows the anchor bolt telescopic device 61 and the anchor bolt rotating device 62 to drive the hydraulic drilling rig 63 to extend, retract, and rotate along the tunnel axis, enabling the hydraulic drilling rig 63 to drill anchor bolt holes in the two sides and the top of the tunnel, facilitating anchor bolt support and improving tunneling efficiency.

[0058] This constitutes the tunnel water-jet drilling machine for supporting anchor bolt support and mesh laying provided by the present invention. Through the cooperation of the drilling mechanism 1, the mesh laying support mechanism 2, the traveling mechanism 3, the manual work platform 4, and the anchor bolt installation mechanism 6, a single machine body can realize the drilling and excavation of the tunnel face, mesh laying, and anchor bolt support without the need for multiple devices to make way and replace in the tunnel, which can effectively improve the tunneling efficiency. At the same time, it can support the sides, top, and ground of the tunnel, effectively improving the operational stability of the tunneling machine and ensuring the reliability of tunnel excavation.

[0059] This invention also provides a tunneling method based on a water-jet tunneling machine that supports anchor bolts and lays mesh, as described above. This tunneling method includes: The manual work platform 4 moves along the axial and vertical directions of the roadway without interfering with the tunneling work, and provides a place for workers to stand. It coordinates the working status of the drilling mechanism 1, the support netting mechanism 2, the traveling mechanism 3, and the anchor bolting mechanism 6.

[0060] First, the drilling of the tunneling face is carried out, the walking mechanism 3 drives the drilling mechanism 1, the support and mesh laying mechanism 2 and the manual operation platform 4 to move synchronously to the tunneling face through the walking track 32 and the ground grabbing device 33, the support and mesh laying mechanism 2 moves along the width direction of the tunnel, after installing the corresponding width of the support frame 221, the support and mesh laying mechanism 2 moves along the height direction of the tunnel, effectively supporting the two sides and the top surface of the tunnel, ensuring the overall stability of the tunneling machine.

[0061] Then, the several water drilling machines 12 in the drilling mechanism 1 simultaneously drill the peripheral contour line and the middle area of the tunneling face, separate the peripheral contour line of the tunneling face from the whole rock, form an empty space, and form a pre-split hole in the middle of the tunneling face, break the gangue by inserting the splitting rod into the pre-split hole and take out the gangue, to complete a cycle of gangue construction.

[0062] Further, the mesh laying is carried out, the support and mesh laying mechanism 2 adsorbs and fixes the mesh on the top surface of the two sides of the tunnel through the support and mesh laying mechanism 2, and carries out mesh laying and fixing.

[0063] Then, the anchor rod support is carried out, the anchor rod drilling mechanism 6 drills and supports the anchor rod on the two sides and the top of the tunnel through the mesh by the hydraulic drilling machine 63.

[0064] The drilling of the tunneling face, the mesh laying and the anchor rod support are realized by a single machine body, without the need for multiple devices to replace in the tunnel, which can effectively improve the construction efficiency, at the same time, can support the two sides, the top surface and the ground of the tunnel, effectively improve the operation stability of the tunneling machine, and ensure the reliability of the tunneling.
