Description

Technical Field

[0001] This invention relates to a tunnel drilling vehicle, and more particularly to an arc-shaped moving device for a tunnel drilling operation vehicle and the tunnel drilling operation vehicle. Background Technology

[0002] Currently, when using engineering vehicles to drill holes in the inner wall of tunnels, both domestically and internationally, the following two methods are commonly used:

[0003] Method 1: Both domestically and internationally, tunnel drilling is often carried out using a combination of manual labor and robotic arms. The robotic arm has a drill gun mounted at the front of its cantilever end, and is mounted on an engineering vehicle. Drilling is performed by rotating and extending the robotic arm.

[0004] However, the above methods result in a longer cantilever end of the robotic arm due to the tunnel height being greater than the operator's height and the drill guns being standard equipment. When drilling, the recoil force from the drill gun impacts the cantilever end of the robotic arm significantly, which can affect the lifespan of the robotic arm.

[0005] Method 2: Install a linear module and linear guide rail at the base of the drill gun on the tunnel drilling vehicle. Use the linear module and linear guide rail to make the drill gun move laterally in a straight line inside the tunnel.

[0006] However, since the tunnel walls are generally curved, the distance between the middle of the linear guide rail and the tunnel wall is relatively far to avoid the end of the linear guide rail from hitting the inner wall. This results in a long cantilever length of the metal detector or drill gun extending out of the linear guide rail when the drill gun is in the middle of the linear guide rail, which affects the stability of the drill gun. If the guide rail is set to be an arc-shaped track that approximates the inner wall of the tunnel to shorten the distance between the middle of the track and the inner wall of the tunnel, the above problem can be effectively improved. However, how to make the drill gun move relative to the arc-shaped track has become a difficult problem for those skilled in the art to study. Summary of the Invention

[0007] The purpose of this invention is to address the problem in the prior art of how to move the drill gun relative to the arc track during tunnel arm drilling operations, and to provide an arc-shaped moving device for a tunnel drilling operation vehicle and a tunnel drilling operation vehicle.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0009] An arc-shaped moving device for a tunnel drilling vehicle includes an arc-shaped track and a transition support, wherein the transition support and the arc-shaped track move relative to each other via a drive assembly, wherein:

[0010] The arc-shaped track has arc-shaped grooves on both sides and arc-shaped teeth on the inner side.

[0011] The transition support has rotating wheels on both sides via a support shaft, and the rotating wheels are in rolling contact with the arc-shaped rail groove on the corresponding side.

[0012] The drive assembly includes a drive gear and a drive mechanism. The drive mechanism is capable of driving the drive gear to rotate, and the drive gear meshes with the arc-shaped teeth.

[0013] The present application describes an arc-shaped moving device for a tunnel drilling vehicle. A transition support has rotating wheels on both sides, which roll in conjunction with the corresponding arc-shaped track grooves. This allows the transition support to move on the arc-shaped track via the rotating wheels. During operation, a drive mechanism drives a drive gear to rotate, causing the drive gear to mesh with the arc-shaped teeth. The drive gear moves relative to the arc-shaped teeth, thereby achieving the purpose of moving the transition support relative to the arc-shaped track. In use, the drill gun is connected to the transition support, allowing the drill gun to move in an arc shape relative to the arc-shaped track along with the transition support.

[0014] Preferably, the drive mechanism is located on one side of the transition support, and a counterweight is provided on the other side of the transition support.

[0015] The drive mechanism, located on one side of the transition support, applies an eccentric bending moment to the transition support, causing it to bear a large overturning moment, which is not conducive to the movement of the transition support. In this case, by setting a counterweight on the other side of the transition support, the eccentric bending moment applied by the drive mechanism to the transition support is balanced, thereby greatly reducing the large overturning moment borne by the transition support, thus optimizing the bearing moment of the transition support and making it more conducive to the movement of the transition support.

[0016] Preferably, the transition support is rotatably fitted with limit wheels at both ends along the length of the arc-shaped track, and the limit wheels are capable of sliding fit with the side of the arc-shaped track.

[0017] Preferably, the top of the arc-shaped track is provided with a top groove along the length of the arc-shaped track, and the transition support is provided with a top protrusion that matches the top groove.

[0018] Preferably, the rotating wheel is a rubber wheel or a plastic wheel, the distance between the top groove and the corresponding top protrusion is H, and the radial elastic deformation of the rotating wheel is T, where T > H.

[0019] During drilling operations, the transition support will bear a large axial force, which will be applied to the rotating wheel. To prevent the support shaft from undergoing irreversible deformation due to the reverse force of drilling over a long period of time, the rotating wheel is made of rubber or plastic. When the rotating wheel bears a large reverse force of drilling, the elastic deformation of the rubber or plastic wheel will reduce the axial force on the transition support. This axial force will act directly on the arc-shaped track through the top protrusion, thereby greatly reducing the load on the support bearing and effectively reducing the degree and probability of irreversible deformation of the support shaft.

[0020] Preferably, the distance H between the top groove and the corresponding top protrusion is: 0.5mm≤H≤2mm.

[0021] Preferably, a vertical seat is provided on the side of the transition support near the drive mechanism, and a horizontal seat is connected to the lower outer side of the vertical seat. The drive mechanism is disposed on the horizontal seat, and the output shaft passes through the vertical seat and is connected to the drive gear. The output shaft and the vertical seat are rotatably engaged by bearings.

[0022] This application also discloses a tunnel drilling vehicle, including a support frame, on which a first telescopic device is supported. The upper part of the first telescopic device is connected to an arc-shaped moving device for a tunnel drilling vehicle as described in this application. The arc-shaped track is arranged laterally along the tunnel drilling vehicle. The first telescopic device can drive the arc-shaped moving device to move closer to or away from the support frame. The first telescopic device is located on one side of the arc-shaped toothed part.

[0023] The tunnel drilling vehicle described in this application is equipped with an arc-shaped moving device for tunnel drilling. Rotating wheels are rotatably fitted on both sides of the transition support, and these rotating wheels roll into the corresponding arc-shaped rail grooves, allowing the transition support to move on the arc-shaped track via the rotating wheels. During operation, a drive mechanism drives the drive gear to rotate, causing the drive gear to mesh with the arc-shaped teeth. The drive gear moves relative to the arc-shaped teeth, thereby achieving the purpose of moving the transition support relative to the arc-shaped track. In use, the drill gun is connected to the transition support, thus achieving the purpose of the drill gun moving arc-shaped relative to the arc-shaped track along with the transition support.

[0024] Meanwhile, the tunnel drilling vehicle described in this application includes a support frame, on which a first telescopic device is supported. The upper part of the first telescopic device is connected to the arc-shaped moving device of the tunnel drilling vehicle described in this application. During construction, the drill gun is connected to the transition support. After the tunnel drilling vehicle described in this application moves to a certain position along the tunnel length direction, the first telescopic device can drive the arc-shaped moving device to move closer to or away from the support frame, so as to realize the purpose of the drill gun moving radially along the tunnel cross-section with the arc-shaped moving device. After the arc-shaped moving device moves radially along the tunnel cross-section to a suitable position, the drill gun moves arc-shaped relative to the arc-shaped track with the transition support, so that the drill gun moves circumferentially along the tunnel cross-section with the transition support, thereby meeting the needs of drilling on the inner wall of the tunnel. Compared with the existing method of completing drilling operations by rotating and extending a robotic arm, the tunnel drilling vehicle based on the above solution has better impact resistance and is more suitable for the environment of tunnel drilling operations.

[0025] Preferably, a drill gun is supported and connected on the transition support.

[0026] Preferably, the tunnel drilling vehicle of this application further includes a frame, and the support frame is disposed on the frame. The support frame is movable relative to the frame along the moving direction of the frame, wherein:

[0027] The frame is equipped with road wheels for the frame to travel on;

[0028] And / or,

[0029] The frame is equipped with rail-shaped wheels, which are used for the frame to travel on the rails.

[0030] By installing road wheels and rail-shaped wheels on the chassis, the tunnel drilling vehicle described in this application meets the requirement of dual-purpose use of both road and rail.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. The arc-shaped moving device for a tunnel drilling vehicle described in this application has rotating wheels on both sides of the transition support. The rotating wheels are in rolling contact with the arc-shaped rail groove on the corresponding side, so that the transition support can move on the arc-shaped rail via the rotating wheels. During operation, the drive mechanism drives the drive gear to rotate, so that the drive gear meshes with the arc-shaped teeth. The drive gear moves relative to the arc-shaped teeth, thereby achieving the purpose of the transition support moving relative to the arc-shaped rail. In use, the drill gun is connected to the transition support, so that the drill gun moves in an arc shape with the transition support relative to the arc-shaped rail.

[0033] 2. The tunnel drilling vehicle described in this application is equipped with the arc-shaped moving device described in this application. Rotating wheels are rotatably engaged on both sides of the transition support. The rotating wheels are in rolling engagement with the arc-shaped rail grooves on the corresponding sides, so that the transition support can move on the arc-shaped rail via the rotating wheels. During operation, the drive mechanism drives the drive gear to rotate, so that the drive gear meshes with the arc-shaped teeth. The drive gear moves relative to the arc-shaped teeth, thereby achieving the purpose of the transition support moving relative to the arc-shaped rail. In use, the drill gun is connected to the transition support, so that the drill gun moves in an arc shape with the transition support relative to the arc-shaped rail.

[0034] 3. The tunnel drilling vehicle described in this application includes a support frame, on which a first telescopic device is supported. The upper part of the first telescopic device is connected to the arc-shaped moving device of the tunnel drilling vehicle described in this application. During construction, the drill gun is connected to a transition support. After the tunnel drilling vehicle described in this application moves to a certain position along the tunnel length direction, the first telescopic device can drive the arc-shaped moving device to move closer to or away from the support frame, so as to realize the purpose of the drill gun moving radially along the tunnel cross-section with the arc-shaped moving device. After the arc-shaped moving device moves radially along the tunnel cross-section to a suitable position, the drill gun moves arc-shaped relative to the arc-shaped track with the transition support, so that the drill gun moves circumferentially along the tunnel cross-section with the transition support, thereby meeting the needs of drilling on the inner wall of the tunnel. Compared with the existing method of completing drilling operations by rotating and extending a robotic arm, the tunnel drilling vehicle based on the above solution has better impact resistance and is more suitable for the tunnel drilling environment than the existing robotic arm that integrates rotation and extension.

[0046] The present invention will now be described in detail with reference to the accompanying drawings.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] Example 1

[0049] The arc-shaped moving device for a tunnel drilling vehicle described in this embodiment includes an arc-shaped track 14 and a transition support 16. The transition support 16 and the arc-shaped track 14 move relative to each other via a drive assembly, wherein:

[0050] like Figures 4-6As shown, the arc-shaped track 14 is provided with arc-shaped track grooves 19 on both sides, and the arc-shaped track 14 is provided with arc-shaped teeth 111 on the inner side. The first telescopic device 15 is located on one side of the arc-shaped teeth 111. The first telescopic device 15 is preferably an electric cylinder, a hydraulic telescopic cylinder, or a linear module.

[0051] The transition support 16 has rotating wheels 110 on both sides via support shaft 128, and the rotating wheels 110 are in rolling contact with the arc-shaped rail groove 19 on the corresponding side.

[0052] The drive assembly includes a drive gear 113 and a drive mechanism 114. The drive mechanism 114 can drive the drive gear 113 to rotate, and the drive gear 113 meshes with the arc-shaped toothed portion 111.

[0053] This embodiment describes an arc-shaped moving device for a tunnel drilling vehicle. The transition support 16 has rotating wheels 110 on both sides. These rotating wheels 110 roll with the corresponding arc-shaped rail groove 19, allowing the transition support 16 to move on the arc-shaped rail 14 via the rotating wheels 110. During operation, the drive mechanism 114 drives the drive gear 113 to rotate, causing the drive gear 113 to mesh with the arc-shaped toothed portion 111. The drive gear 113 moves relative to the arc-shaped toothed portion 111, thereby achieving the purpose of moving the transition support 16 relative to the arc-shaped rail 14. In use, the drill rig 22 is connected to the transition support 16, thus achieving the purpose of the drill rig 22 moving arc-shaped relative to the arc-shaped rail 14 along with the transition support 16.

[0054] like Figure 5 As shown, the drive mechanism 114 moves synchronously with the transition support 16. To prevent the drive mechanism 114 from interfering with the first telescopic device 15, the drive mechanism 114 is positioned on one side of the transition support 16. However, the drive mechanism 114 will apply an eccentric bending moment to the transition support 16, causing the transition support 16 to bear a large overturning moment, which is not conducive to the movement of the transition support 16. In this case, by setting a counterweight 115 on the other side of the transition support 16, the eccentric bending moment applied by the drive mechanism 114 to the transition support 16 is balanced, which greatly reduces the large overturning moment borne by the transition support 16, thereby optimizing the bearing moment of the transition support 16 and making it more conducive to the movement of the transition support 16.

[0055] like Figure 5As shown, the transition support 16 includes a top plate 112 and a vertical seat 132 disposed on one side near the drive mechanism 114. The top of the vertical seat 132 is connected to the top plate 112, and a horizontal seat 131 is connected to the lower outer side of the vertical seat 132. The drive mechanism 114 is disposed on the horizontal seat 131, and the output shaft 129 passes through the vertical seat 132 and is connected to the drive gear 113. The output shaft 129 and the vertical seat 132 are rotatably engaged by bearings.

[0056] like Figure 4 As shown, the transition support 16 is rotatably fitted with limit wheels 124 at both ends along the length of the arc track 14. The limit wheels 124 can slide with the side of the arc track 14. The limit wheels 124 are provided on both sides of the transition support 16. At least one limit wheel 124 has a gap 125 between it and the arc track 14. The width of the gap 125 is L, preferably 0.1mm≤L≤5mm.

[0057] Based on the above, in a further preferred embodiment, the top of the arc-shaped track 14 is provided with a top groove 126 along the length direction of the arc-shaped track 14, and the transition support 16 is provided with a top protrusion 127 that matches the top groove 126.

[0058] Based on the above, in a further preferred manner, the distance between the top groove 126 and the corresponding top protrusion 127 is H, and the radial elastic deformation of the rotating wheel 110 is T, where T > H. When drilling is performed, the transition support 16 will bear a large drilling reverse force, which will be applied to the support shaft 128 and the rotating wheel 110. To prevent the support shaft 128 from undergoing irreversible deformation due to bearing a large drilling reverse impact force for a long time, when the rotating wheel 110 bears a large drilling reverse force, since the radial elastic deformation T of the rotating wheel 110 is greater than the distance H between the top groove 126 and the corresponding top protrusion 127, the elastic deformation of the rotating wheel 110 ensures that when the transition support 16 bears a large reverse impact force, the reverse impact force is directly applied to the arc-shaped track 14 through the top protrusion 127. This effectively controls the upper limit of the load that the support shaft 128 can bear, thereby effectively reducing the degree and probability of irreversible deformation of the support shaft 128.

[0059] The rotating wheel 110 can be specifically selected as a rubber wheel or a plastic wheel.

[0060] Specifically, the distance H between the top groove 126 and the corresponding top protrusion 127 is: 0.5mm≤H≤2mm.

[0061] Specifically, a vertical seat 132 is provided on the side of the transition support 16 near the drive mechanism 114. A horizontal seat 131 is connected to the lower outer side of the vertical seat 132. The drive mechanism 114 is disposed on the horizontal seat 131. The output shaft 129 passes through the vertical seat 132 and is connected to the drive gear 113. The output shaft 129 and the vertical seat 132 are rotatably engaged by bearings.

[0062] Specifically, the drive mechanism 114 is a motor, which has an output shaft 129. The drive gear 113 is sleeved and fixed at the front end of the output shaft 129 and rotates together with the output shaft 129.

[0063] Example 2

[0064] like Figures 1-11 As shown, the tunnel drilling vehicle of this embodiment includes a support frame 13, on which a first telescopic device 15 is supported. The upper part of the first telescopic device 15 is connected to an arc-shaped moving device for the tunnel drilling vehicle as described in Embodiment 1. The arc-shaped track 14 is arranged laterally along the tunnel drilling vehicle. The first telescopic device 15 can drive the arc-shaped moving device to move closer to or away from the support frame 13. A drill gun 22 is connected to the transition support 16.

[0065] This embodiment describes a tunnel drilling vehicle equipped with the arc-shaped moving device described in this application. Rotating wheels 110 are rotatably fitted on both sides of the transition support 16. The rotating wheels 110 roll with the corresponding arc-shaped rail groove 19, allowing the transition support 16 to move on the arc-shaped rail 14 via the rotating wheels 110. During operation, the drive mechanism 114 drives the drive gear 113 to rotate, causing the drive gear 113 to mesh with the arc-shaped toothed portion 111. The drive gear 113 moves relative to the arc-shaped toothed portion 111, thereby achieving the purpose of the transition support 16 moving relative to the arc-shaped rail 14. In use, the drill rig 22 is connected to the transition support 16, thus achieving the purpose of the drill rig 22 moving arc-shaped relative to the arc-shaped rail 14 along with the transition support 16.

[0066] Meanwhile, the tunnel drilling vehicle described in this application includes a support frame 13, on which a first telescopic device 15 is supported. The upper part of the first telescopic device 15 is connected to the arc-shaped moving device of the tunnel drilling vehicle described in this application. During construction, the drill rig 22 is connected to the transition support 16. After the tunnel drilling vehicle described in this application moves to a certain position along the tunnel length direction, the first telescopic device 15 can drive the arc-shaped moving device to move closer to or away from the support frame 13, thereby achieving the purpose of the drill rig 22 moving radially along the tunnel cross-section with the arc-shaped moving device. After moving radially along the tunnel cross-section to a suitable position, the drill rig 22 moves in an arc shape relative to the arc track 14 with the transition support 16, so that the drill rig 22 moves circumferentially along the tunnel cross-section with the transition support 16, thereby meeting the requirements of the drill rig 22 to perform drilling operations on the inner wall 100 of the tunnel. Compared with the existing method of completing drilling operations by rotating and extending a robotic arm, the tunnel drilling vehicle based on the above scheme has better impact resistance and is more suitable for the environment of tunnel drilling operations. The first telescopic device 15 and the arc-shaped moving device with unidirectional movement have better impact resistance than the existing robotic arm that needs to integrate rotation and telescopic movement.

[0067] The tunnel drilling vehicle described in this application further includes a frame 3, with a support frame 13 mounted on the frame 3. The support frame 13 is movable relative to the frame 3 along the direction of movement of the frame 3. The wheels on the frame 3 are installed in three ways:

[0068] Case 1: The frame 3 is equipped with road wheels 33 for the frame 3 to travel on.

[0069] Scenario 2: The frame 3 is provided with rail-shaped wheels 34, which are used for the frame 3 to travel on the rails 36.

[0070] like Figures 10-11 As shown in Case 3, the frame 3 is equipped with both road wheels 33 for traveling on the road and rail wheels 34 for traveling on the rails 36. In this case, the bottom of the rail wheels 34 is slightly higher than the bottom of the road wheels 33 to ensure that the bottom of the rail wheels 34 does not interfere with the ground when traveling on the road. When traveling on the rails 36, since the top of the rails 36 is higher than the ground, the bottom of the rail wheels 34 is slightly higher than the bottom of the road wheels 33 to ensure that the road wheels 33 do not interfere with the ground at the rails 36. Alternatively, the rail wheels 34 or road wheels 33 can be made to move vertically up and down, adjusting their relative height in the vertical direction. By equipping the frame 3 with road wheels 33 and rail wheels 34, the tunnel drilling vehicle described in this application meets the requirement of dual-purpose use on a shared rail system.

[0071] Example 3

[0072] like Figures 1-11 As shown, the tunnel drilling vehicle described in this embodiment is a specific application of the arc-shaped moving device for tunnel drilling vehicles described in Embodiment 1 or the tunnel drilling vehicle described in Embodiment 2. The tunnel drilling vehicle includes a front frame 1 and a rear frame 2 spaced apart. A metal detection device 11 and a marking device 12 are mounted on the front frame 1, and the metal detection device 11 and marking device 12 are fixedly arranged relative to each other. An identification device 21 and a drill rig 22 are mounted on the rear frame 2, and the identification device 21 and drill rig 22 are fixedly arranged relative to each other. The marking device 12 is used to mark the identification part 10, and the identification device 21 is used to identify the identification part 10. To avoid damaging the reinforcing steel bars inside the tunnel wall 100 during drilling, the construction is divided into two steps: detection and marking, and identification and drilling.

[0073] Detection Marking: Move the front frame 1 and use the metal detection device 11 on the front frame 1 to perform detection operations to detect the metal inside the tunnel inner wall 100, and find the drilling location area F1 on the tunnel inner wall 100 based on the detected metal inside the tunnel inner wall 100. If the metal detection device 11 cannot detect the metal inside the tunnel inner wall 100 in a certain area, then that area is the drilling location area F1. The metal detection device 11 and the marking device 12 are relatively fixed, so the marking device 12 is used to mark the tunnel inner wall to form a marking part 10. The marking part 10 is used to characterize the drilling location area on the tunnel inner wall 100, for example, by spraying a pattern or pasting a pattern. Then the metal detection device 11 cooperates with the marking device 12 to find and mark the next drilling location area.

[0074] Identification and drilling: Move the rear frame 2 and use the identification device 21 on the rear frame 2 to identify the marking part 10 on the inner wall of the tunnel. After the identification device 21 identifies the marking part 10, since the identification device 21 and the drill gun 22 are relatively fixed, the drill gun 22 performs drilling operation based on the position of the identification device 21, so that the hole drilled by the drill gun 22 is located in the drilling area.

[0075] The arc-shaped moving device for a tunnel drilling vehicle described in this application, through the marking device 12 and the identification device 21, separates the detection operation of the metal detector 11 from the drilling operation of the drill gun 22 while ensuring that the drilling operation is within the designated area. This effectively reduces the time spent by the operator in changing detectors and drilling operations, thereby greatly improving the detection efficiency of the metal detector 11. Furthermore, during the entire detection and drilling process, the operator only needs to control the actions of the metal detector 11 and the marking device 12, as well as the identification device 21 and the drill gun 22. The operator does not need to repeatedly lift the metal detector overhead for detection operations, nor does the operator need to be close to the drilling location. This effectively reduces the labor intensity of manual operations and the severity of the harsh working environment for the operator.

[0076] In the above scheme, the metal detection device 11 is preferably a rebar locator, a metal detector, or a rebar scanner. Taking a rebar scanner as an example: the rebar scanner can be the HC-GY71T integrated rebar scanner from Haichuang Gaoke Company. This rebar scanner is a portable intelligent non-destructive testing device used to detect the construction quality of reinforced concrete structures. It can detect the thickness of the rebar protective layer, the position, direction and distribution of the rebar, and can also detect magnetic and conductive materials in non-magnetic and non-conductive media.

[0077] The marking device 12 is preferably a marking gun, or, for example, a marking gun: the marking gun can be a WZ-MFS model linear spray gun or a WZ-MMFS model spray gun from the German brand Schutze, which can spray circular or fan-shaped marking parts 10, and the spraying medium can be paint or colorant.

[0078] The identification device 21 is preferably an identification camera or webcam, such as the Keyence CV-X series identification camera. A horn-shaped housing can be fitted around the front of the identification camera to help control the identification range of the camera.

[0079] Drilling equipment 22 preferably uses a drill gun.

[0080] like Figures 8-9 As shown, in a further preferred embodiment, based on the above, the marking device 12 is located on the first side of the metal detection device 11, and the identification device 21 is also located on the first side of the drill rig 22. The distance between the marking device 12 and the metal detection device 11 is T1, and the distance between the identification device 21 and the drill rig 22 is T2, where T1=T2.

[0081] Since the marking device 12, metal detector 11, identification device 21, and drill 22 themselves have width, if the marking device 12 is tilted relative to the metal detector 11 so that the marking part 10 is located within the drilling area F1, the identification device 21 and the drill 22 also need to be tilted. This makes adjustment and installation during construction very troublesome. In the arc-shaped moving device for a tunnel drilling vehicle described in this application, since the marking device 12 is located on the first side of the metal detector 11, and the identification device 21 is also located on the first side of the metal detector 11... The first side of the drill rig 22 is positioned so that the marking device 12 and the identification device 21 are on the same side. During construction, the distance T1 between the marking device 12 and the metal detection device 11 is used to compensate for the distance T2 between the identification device 21 and the drill rig 22. This ensures that when the marking part 10 is within the identification range F2 of the identification device 21, the drill rig 22 can be aligned with the drilling location area F1. This ensures that the hole drilled by the drill rig 22 is located in the drilling location area F1 on the tunnel inner wall 100. No angle adjustment is required during construction, making construction convenient.

[0082] The assembly of the front frame 1 and the rear frame 2 with the vehicle frame 3 includes the following two methods:

[0083] like Figure 1 As shown, firstly, the frame 3 is a single unit, with both the front frame 1 and the rear frame 2 mounted on it. Specifically, the frame 3 is provided with a track 31, and both the front frame 1 and the rear frame 2 are slidably engaged with the track 31. The direction of movement of the front frame 1 relative to the frame 3 is parallel to the direction of movement of the rear frame 2 relative to the frame 3.

[0084] Based on the above, a further preferred method is that, during construction, after reaching a certain position in the tunnel, the vehicle frame 3 is fixed, and the front frame 1 is moved on the vehicle frame 3. The metal detection device 11 on the front frame 1 is used to perform detection work to find the location area F1 on the tunnel inner wall 100 where a hole can be drilled.

[0085] Then, the position of the front frame 1 is marked using the positioning device 32, and the marking device 12 is used to mark the inner wall of the tunnel to form an identification part 10. The identification part 10 is used to characterize the area F1 on the inner wall 100 where holes can be drilled.

[0086] Then, the front frame 1 was removed to probe the area F1 where drilling was possible;

[0087] Then move the rear frame 2 until the rear frame 2 is positioned and engaged with the positioning device 32. At this time, stop the rear frame 2 and use the identification device 21 on the rear frame 2 to identify the marking part 10 on the inner wall of the tunnel.

[0088] After the identification device 21 identifies the identification part 10, the drill rig 22 performs drilling operations based on the position of the identification device 21.

[0089] By setting the positioning device 32, the rear frame 2 can quickly reach the position of the front frame 1 when the marking device 12 is performing marking operations on the inner wall of the tunnel, thereby greatly shortening the time for the identification device 21 to find the identification mark 10 along the tunnel length direction. The identification device 21 only needs to find the mark 10 along the tunnel cross-section axial direction, which is convenient, fast and time-saving.

[0090] Specifically, a positioning block 35 protrudes from the rear frame 2, and the positioning device 32 can be positioned and engaged with the positioning block 35. The positioning device 32 is magnetically connected to the vehicle frame 3 or the front frame 1; the positioning block 35 is a switch, and the switch can be positioned and engaged with the positioning device 32; the positioning device 32 is a T-shaped structure or an L-shaped plate structure.

[0091] like Figure 11 As shown, secondly, there are two frames 3, with the front frame 1 mounted on one of the frames 3 and the rear frame 2 mounted on the other frame 3.

[0092] The frame 3 is provided with road wheels 33 for the frame 3 to travel on;

[0093] The frame 3 is equipped with rail-shaped wheels 34, which are used for the frame 3 to travel on the rails 36.

[0094] The front frame 1 includes an arc-shaped moving device for a tunnel drilling vehicle as described in Embodiment 1, or the rear frame 2 includes an arc-shaped moving device for a tunnel drilling vehicle as described in Embodiment 1, or both the front frame 1 and the rear frame 2 include an arc-shaped moving device for a tunnel drilling vehicle as described in Embodiment 1. The following description uses the front frame 1 as an example:

[0095] The front frame 1 includes a support frame 13, on which at least two arc-shaped tracks 14 are supported. Adjacent arc-shaped tracks 14 on the same support frame 13 are spaced apart. The at least two arc-shaped tracks 14 are arranged circumferentially around the support frame 13. A transition support 16 is slidably mounted on the arc-shaped track 14. The support frame 13 and the arc-shaped track 14 are telescopically connected in the direction toward the outside of the support frame 13 by a first telescopic device 15. The metal detection device 11 and the marking device 12 are mounted on the transition support 16.

[0096] The tunnel drilling vehicle described in this embodiment includes a front frame 1 comprising a support frame 13, on which at least two arc-shaped tracks 14 are supported. Adjacent arc-shaped tracks 14 on the same support frame 13 are spaced apart, and the at least two arc-shaped tracks 14 are arranged circumferentially around the support frame 13. A transition support 16 is slidably mounted on the arc-shaped track 14. The support frame 13 and the arc-shaped track 14 are telescopically connected via a first telescopic device 15 in the direction toward the outside of the support frame 13. The metal detection device 11 and the marking device 12 are mounted on the transition support 16.

[0097] During construction: After the front frame 1 reaches a certain position, the metal detection device 11 and the marking device 12 can detect and mark along the circumference of the tunnel inner wall by the relative movement of the transition support 16 and the arc track 14. In this process, at least two arc tracks 14 are set up, and each arc track 14 is equipped with a metal detection device 11 and a marking device 12. Adjacent arc tracks 14 are spaced apart and do not interfere with each other, so that at least two sets of metal detection devices 11 and marking devices 12 can work simultaneously to detect and mark different areas where holes can be drilled, thereby greatly increasing the construction efficiency of wall reinforcement detection and marking operations.

[0098] Meanwhile, based on the fact that the adjacent arc-shaped tracks 14 are spaced apart and do not interfere with each other, the first telescopic device 15 enables the arc-shaped tracks 14, the transition support 16, the metal detection device 11 and the marking device 12 to move radially along the tunnel, thereby enabling the tunnel drilling vehicle described in this embodiment to meet the detection and marking operations of the steel bars 100 on the inner wall of the tunnel with different cross-sectional sizes or shapes.

[0099] Specifically, the support frame 13 on the front frame 1 is a portal frame structure, a truss structure, or a box girder structure.

[0100] Based on the above, in a further preferred manner, the arc-shaped track 14 on the front frame 1 is disposed on the outside of the support frame 13.

[0101] Similarly, when the rear frame 2 includes an arc-shaped moving device for a tunnel drilling vehicle as described in Embodiment 1, the rear frame 2 includes a support frame 13, on which at least two arc-shaped tracks 14 are supported. Adjacent arc-shaped tracks 14 on the same support frame 13 are spaced apart, and at least two arc-shaped tracks 14 are arranged circumferentially around the support frame 13. A transition support 16 is slidably provided on the arc-shaped track 14. In the direction toward the outside of the support frame 13, the support frame 13 and the arc-shaped track 14 are telescopically connected by a first telescopic device 15. The identification device 21 and the drill gun 22 are installed on the transition support 16.

[0102] During construction: After the rear frame 2 reaches a certain position, the relative movement of the transition support 16 and the arc-shaped track 14 enables the identification device 21 and the drill gun 22 to identify and drill along the circumferential direction of the tunnel inner wall. During this process, at least two arc-shaped tracks 14 are set up, and each arc-shaped track 14 is equipped with an identification device 21 and a drill gun 22. Adjacent arc-shaped tracks 14 are spaced apart and do not interfere with each other, so that at least two sets of identification devices 21 and drill guns 22 can work simultaneously to identify their different drilling locations, thereby greatly increasing the construction efficiency of tunnel drilling.

[0103] Meanwhile, based on the fact that the adjacent arc-shaped tracks 14 are spaced apart and do not interfere with each other, the first telescopic device 15 enables the arc-shaped tracks 14, the transition support 16, the identification device 21 and the drill gun 22 to move radially along the tunnel, thereby enabling the tunnel drilling vehicle described in this embodiment to meet the needs of tunnel drilling operations with different cross-sectional sizes or different cross-sectional shapes.

[0104] like Figure 7As shown, when the support frame 13 and the arc-shaped track 14 are telescopically connected by the first telescopic device 15, the first telescopic device 15 serves as a support for the arc-shaped track 14. During operation, as the transition support 16 moves on the arc-shaped track 14, when the transition support 16 moves to a position far from the first telescopic device 15, it will generate a large eccentric bending moment on the first telescopic device 15. If multiple first telescopic devices 15 are set, they need to extend and retract synchronously, which results in high control costs. Therefore, a support telescopic device 217, such as a hydraulic cylinder, pneumatic cylinder, or jack, is hinged on the support frame 13. When the first telescopic device 15 extends and retracts to its position, and the transition support 16 moves to the predetermined position, the support telescopic device 217 is extended and retracted and abuts against the position of the arc-shaped track 14 near the transition support 16, thereby effectively reducing the eccentric bending moment borne by the first telescopic device 15 and greatly increasing the stability of the arc-shaped track 14. The support frame 13 is hinged with a support telescopic device 217, which can support two adjacent arc-shaped tracks 14. The support telescopic device 217 is preferably an electric cylinder, a hydraulic telescopic cylinder, or a linear module.

[0105] Based on the above, in a further preferred embodiment, the front end of the supporting telescopic device 217 is rotatably fitted with an abutment wheel, and an abutment groove 226 is provided on the inner arc of the arc-shaped track 14, the abutment groove 226 abutting against the abutment wheel 225. The abutment groove 226 is used to prevent the second telescopic device from being unstable in contact with the arc-shaped track 14. The second telescopic device is preferably an electric cylinder, a hydraulic telescopic cylinder, or a linear module.

[0106] Specifically, the support frame 13 is provided with a second ear plate 221, which is rotatably engaged with the support telescopic device 217.

[0107] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
