Description

Technical Field

[0001] The present invention relates to the technical field of geotechnical engineering, and in particular to an anchor rod and anchor cable drilling positioning auxiliary device. Background Art

[0002] An anchor is a tension rod anchored in the rock or soil at one end and connected to a structure or the surface of the rock or soil at the other end. Through the bond or friction between the anchor and the rock or soil, the tension of the rock or soil is transferred to the stable stratum, thereby improving the stability of the rock or soil and preventing its deformation and collapse.

[0003] Anchor cables are tension rods made of high-strength steel materials such as stranded wire and wire bundles. They are anchored deep into stable rock and soil through drilling, using the tension of the cable to limit deformation and displacement of the rock and soil. Anchor cables are typically prestressed, which effectively controls deformation and improves structural stability.

[0004] The existing Chinese patent with publication number CN118979495B discloses a slope anchor hole straightening auxiliary device and a construction quality assurance method. However, the above patent also has the following defects:

[0005] First, the guide assembly for the operating platform in the above-mentioned patent is directly installed on the slope. In actual operation, the surface of the slope is unlikely to be completely flat. Therefore, when installing the guide assembly, the guide assembly will be skewed, which will eventually affect the forward direction of the operating platform. If the slope is surface treated, the workload will increase and the drilling efficiency will be reduced. In addition, after the guide assembly is installed, the weight of the operating platform will act on the slope, causing damage to the slope, resulting in cracks in the slope and even landslides on rainy days.

[0006] Secondly, when drilling holes in the slope, several evenly distributed holes need to be drilled on the entire slope. The above patent can only locate and drill holes in a small part of the entire slope. If the drilling position is changed, the guide assembly needs to be removed and reinstalled after the position is changed, which will increase the work intensity and waste a lot of time.

[0007] Therefore, in view of the above problems, it is necessary to provide an anchor rod and anchor cable drilling positioning auxiliary device to solve them. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] First, the drilling platform of the device is installed on a flip stand. When drilling holes, the flip stand will flip to be parallel to the slope. The feed drill installed on the drilling platform can directly move forward to drill holes in the slope. The flip stand does not contact the slope, so it does not exert any pressure on the slope, ultimately preventing the slope from cracking and landslide due to pressure.

[0020] Secondly, the flip stand of the device is arranged on a mobile base. During the actual process of drilling holes in the slope, when all holes are drilled in a certain area of the slope, the mobile base can drive the flip stand to move along the extended length of the slope. Then, the drilling platform arranged on the flip stand can drive the feed drill to move toward the undrilled area of the slope. Compared with the above-mentioned patent, which requires the disassembly of the guide assembly to change its position, the present device does not require any unnecessary disassembly work, shortening the work process and improving the drilling efficiency.

[0021] Thirdly, the device controls the flipping of the flip stand by retracting and unreeling the traction rope through the No. 1 rotating drum. When the No. 1 rotating drum stops moving, the self-locking mechanism of the device can lock the No. 1 rotating drum, thereby ensuring that the flip stand is stable in its current position after stopping flipping;

[0022] Fourthly, when not working, the flip stand cooperates with the lifting lock frame on the supporting stand through the two limit rods thereon, so as to lock the flip stand on the supporting stand, thereby avoiding the pulling force of the flip stand on the traction rope when not working, thereby extending the service life of the traction rope.

[0043] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] refer to Figures 1 to 19 The anchor bolt and anchor cable drilling positioning auxiliary device shown in the figure comprises a mobile base 1, a support frame 2 is provided on the mobile base 1, and a balance sinker 3 (such as Figure 7As shown), a flip stand 4 is provided on the side of the support stand 2, and the bottom of the flip stand 4 is hinged to the mobile base 1. A plurality of distance sensors 5 are provided on the side of the flip stand 4 away from the support stand 2, and the plurality of distance sensors 5 are evenly distributed along the length direction of the flip stand 4. A drilling platform 6 and a translation drive mechanism are provided on the flip stand 4. The drilling platform 6 is slidably connected to the flip stand 4, and the length direction of the drilling platform 6 is perpendicular to the length direction of the flip stand 4. The translation drive mechanism is used to drive the drilling platform 6 to translate along the length direction of the flip stand 4. A self-locking traction component is provided on the top of the support stand 2. The self-locking traction assembly includes a No. 1 rotating drum 7, a rotary drive mechanism, two traction ropes 8 and two self-locking mechanisms. The No. 1 rotating drum 7 is horizontally connected to the top of the supporting frame 2 for rotation. The two traction ropes 8 are symmetrically wound around the No. 1 rotating drum 7. One end of each traction rope 8 is vertically downward and connected to the balance weight 3. The other end of each traction rope 8 is tilted downward and connected to the top of the flip frame 4. The two self-locking mechanisms are respectively provided at both ends of the No. 1 rotating drum 7. Each self-locking mechanism is used to lock the No. 1 rotating drum 7. The rotary drive mechanism is provided on the side of the No. 1 rotating drum 7. The rotary drive mechanism is used to drive the No. 1 rotating drum 7 to rotate.

[0045] This device is used to assist in positioning anchor holes during slope reinforcement. The specific operation process is as follows: When not working, the No. 1 rotating drum 7 pulls the flip stand 4 through two traction ropes 8 to flip and gradually approach the support stand 2, and finally makes the flip stand 4 tilted (such as Figure 1 As shown), when working, the mobile base 1 is moved to the land beside the slope, and the flip stand 4 is made to face the slope. At this time, the flip stand 4 will tilt towards the slope (as shown in FIG. Figure 18 As shown), in actual use, a feed drill (not shown in the figure) is installed on the drilling rig platform 6, and the forward direction of the feed drill is parallel to the length direction of the drilling rig platform 6. Thereafter, the rotary drive mechanism drives the No. 1 rotary drum 7 to rotate, and the No. 1 rotary drum 7 synchronously unwinds the two traction ropes 8, so that the flip frame 4 will turn to the slope due to gravity, and a number of distance sensors 5 provided on one side of the flip frame 4 will gradually approach the slope. During this process, each distance sensor 5 will monitor the distance to the slope in real time. Since the several distance sensors 5 are equidistantly distributed along the length direction of the flip frame 4, when the distances monitored by the several distance sensors 5 are close to each other, then the flip frame 4 is parallel to the slope (as shown in the figure). Figure 19When the first drum 7 rotates and drives the flip frame 4 to flip toward the slope, the two traction ropes 8 will synchronously drive the balancing weight 3 to rise, and the balancing weight 3 is used to balance the weight of the flip frame 4 to prevent the flip frame 4 from being too heavy and overturning the first drum 7.

[0046] In order to show the specific structure of each self-locking mechanism, the following features are set:

[0047] Each self-locking mechanism includes a rotating disk 9, a ratchet ring 10, a driving disk 11, two No. 1 locking blocks 12 and two No. 2 locking blocks 13. The rotating disk 9 is coaxially fixed to the No. 1 rotating drum 7 (such as Figure 13 As shown), the ratchet ring 10 is fixedly connected to the support stand 2, and the ratchet ring 10 is coaxial with the turntable 9. A circle of No. 1 ratchet teeth 14 and a circle of No. 2 ratchet teeth 15 are formed on the inner ring of the ratchet ring 10, and the tooth directions of each No. 1 ratchet tooth 14 and No. 2 ratchet teeth 15 are opposite. Four strip chute 16 are formed on one side of the turntable 9. The four strip chute 16 are evenly distributed along the circumferential direction of the turntable 9. The length direction of each strip chute 16 is consistent with the radial direction of the turntable 9. The two No. 1 locking blocks 12 are symmetrically slidably arranged in two of the strip chute 16, and the two No. 2 locking blocks 1 3 is symmetrically slidably arranged in the other two strip-shaped slide grooves 16. Each No. 1 lock block 12 and No. 2 lock block 13 are elastically connected to the turntable 9. One end of each No. 1 lock block 12 is provided with a No. 1 pawl 17 that cooperates with the No. 1 ratchet 14. One end of each No. 2 lock block 13 is provided with a No. 2 pawl 18 that cooperates with the No. 2 ratchet 15. The drive disk 11 is coaxially connected to the turntable 9. A telescopic drive member is provided between the drive disk 11 and the turntable 9 for respectively driving the No. 1 lock block 12 and the No. 2 lock block 13 to extend and retract. Each drive disk 11 is connected to the rotation drive mechanism.

[0048] When the driving disk 11 does not rotate, each No. 1 lock block 12 and No. 2 lock block 13 will extend toward the ratchet ring 10 along the corresponding strip-shaped sliding groove 16 by elasticity. At this time, the No. 1 pawl 17 on the No. 1 lock block 12 will be engaged between two adjacent No. 1 ratchet teeth 14, and the No. 2 pawl 18 on the No. 2 lock block 13 will be engaged between two adjacent No. 2 ratchet teeth 15 (such as Figure 14As shown in the figure), since the tooth directions of the No. 1 ratchet 14 and the No. 2 ratchet 15 are opposite, and the turntable 9 is coaxially fixed to the No. 1 drum 7, the No. 1 drum 7 cannot rotate forward or reverse at this time, and finally ensures that the flip stand 4 and the balance weight 3 at both ends of each traction rope 8 can be stable in the current position and will not be displaced by gravity. When the rotary drive mechanism drives the drive disk 11 to rotate counterclockwise, the telescopic drive member will first drive the two No. 1 lock blocks 12 to retract synchronously. After the two No. 1 lock blocks 12 are retracted synchronously, each No. 1 pawl 17 will separate from between the two adjacent No. 1 ratchets 14. Thereafter, the drive disk 11 will drive the turntable 9 to rotate. When the turntable 9 rotates, each No. 1 lock block 12 and No. 2 lock block 13 will rotate together with the turntable 9. During the process, since each No. 1 pawl 17 is separated from the No. 1 ratchet 14, the No. 1 locking block 12 will not affect the normal rotation of the turntable 9 at this time, and each No. 2 pawl 18 slides between several No. 2 ratchets 15 through the inclined surface thereon and the elasticity between the No. 2 locking block 13 and the turntable 9, so the No. 2 locking block 13 will not affect the normal rotation of the turntable 9 at this time. Finally, the turntable 9 will drive the No. 1 rotating drum 7 to unwind the two traction ropes 8, so that the flip stand 4 is flipped toward the slope. When the flip stand 4 is flipped to be parallel to the slope, the driving disk 11 stops rotating. At this time, each No. 1 locking block 12 and No. 2 locking block 13 will again extend toward the ratchet ring 10 along the corresponding strip slide 16 through elasticity, and finally the turntable 9 will be locked again.

[0049] In order to show the specific structure of the telescopic drive, the following features are set:

[0050] Each turntable 9 is coaxially formed with a rotating shaft 19 on the side away from the No. 1 rotating drum 7, and each driving disk 11 rotates coaxially on the corresponding rotating shaft 19. A No. 1 spring 20 is provided between each No. 1 locking block 12 and the rotating shaft 19, and the two ends of the No. 1 spring 20 respectively conflict with the No. 1 locking block 12 and the rotating shaft 19. A No. 2 spring 21 is provided between each No. 2 locking block 13 and the rotating shaft 19, and the two ends of the No. 2 spring 21 respectively conflict with the No. 2 locking block 13 and the rotating shaft 19. Each telescopic driving member includes two No. 1 inclined plane blocks 22, two No. 2 inclined plane blocks 23, two No. 1 driving pins 24 and two No. 2 driving pins 25. The two No. 1 inclined plane blocks 22 are respectively connected to the two No. 1 locking blocks 12, and the two No. 2 inclined plane blocks 23 are respectively connected to the two No. 2 locking blocks 13. Each No. 1 driving pin 24 and No. 2 driving pin 25 are fixedly connected to the driving disk 11 (such as Figure 16 As shown), the two No. 1 drive pins 24 correspond to the two No. 1 inclined plane blocks 22 respectively, and the two No. 2 drive pins 25 correspond to the two No. 2 inclined plane blocks 23 respectively. Each No. 1 drive pin 24 and No. 2 drive pin 25 extends horizontally into the corresponding strip-shaped slide groove 16.

[0051] When the driving disk 11 stops rotating, each of the No. 1 driving pin 24 and the No. 2 driving pin 25 is in the middle position of the corresponding strip-shaped sliding groove 16 (eg Figure 14 As shown), at this time, the No. 1 drive pin 24 is not in contact with the No. 1 inclined block 22, and the No. 2 drive pin 25 is not in contact with the No. 2 inclined block 23, then the No. 1 spring 20 will drive the No. 1 lock block 12 to be in an extended state through its elastic force, and the No. 2 spring 21 will drive the No. 2 lock block 13 to be in an extended state through its elastic force, and finally each No. 1 pawl 17 will be engaged between two adjacent No. 1 ratchet teeth 14, and each No. 2 pawl 18 will be engaged between two adjacent No. 2 ratchet teeth 15. At this time, the turntable 9 is locked by the No. 1 lock block 12 and the No. 2 lock block 13 and cannot be rotated. When the driving mechanism drives the driving disk 11 to rotate counterclockwise, the driving disk 11 will synchronously drive each No. 1 driving pin 24 and No. 2 driving pin 25 to revolve. During this process, the No. 2 driving pin 25 will directly conflict with the corresponding bar-shaped slide groove 16, and the No. 1 driving pin 24 will first conflict with the No. 1 inclined block 22. At this time, the No. 1 locking block 12 will retract due to the cooperation between the No. 1 inclined block 22 and the No. 1 driving pin 24. When the No. 1 locking block 12 retracts, the No. 1 pawl 17 will separate from the No. 1 ratchet 14. When the No. 1 pawl 17 separates from the No. 1 ratchet 14, The No. 1 driving pin 24 will conflict with the corresponding strip slide 16, and finally the driving disc 11 will drive the turntable 9 to rotate through the No. 1 driving pin 24 and the No. 2 driving pin 25 to unwind the traction rope 8. When the flip stand 4 flips to be parallel to the slope, the driving disc 11 stops rotating. At this time, the No. 1 locking block 12 and the No. 2 locking block 13 are extended again by the elastic force of the No. 1 spring 20 and the No. 2 spring 21 respectively, so that the turntable 9 will be locked again. When it is necessary to drive the flip stand 4 to reset, the rotary drive mechanism will drive the driving disc 11 to rotate in the opposite direction. During this process , the No. 2 driving pin 25 will conflict with the No. 2 inclined surface block 23, thereby realizing the retraction of the No. 2 locking block 13, and then separating the No. 2 pawl 18 from the adjacent No. 2 ratchet 15, and the No. 1 pawl 17 will slide between several No. 1 ratchet teeth 14 through its inclined surface and the elasticity of the No. 1 spring 20. In summary, no matter whether the driving disk 11 rotates forward or reverse, the No. 1 rotating drum 7 will be driven to rotate by the driving disk 11 through the rotating disk 9. When the driving disk 11 stops, the rotating disk 9 will be immediately locked by the No. 1 locking block 12 and the No. 2 locking block 13, and finally the self-locking of the No. 1 rotating drum 7 is realized.

[0052] In order to show the specific structure of the rotary drive mechanism, the following features are set:

[0053] The rotary drive mechanism includes a transmission shaft 26, a reduction motor 27 and two synchronous transmission parts. The transmission shaft 26 is rotatably arranged at the top of the support stand 2, and the axial direction of the transmission shaft 26 is parallel to the axial direction of the No. 1 rotating drum 7. The reduction motor 27 is horizontally fixed at the top of the support stand 2, and the output end of the reduction motor 27 is coaxially connected to the transmission shaft 26. The two synchronous transmission parts are respectively arranged at the two ends of the No. 1 rotating drum 7. Each synchronous transmission part includes a No. 1 synchronous wheel 28, a No. 2 synchronous wheel 29 and a synchronous belt 31. The No. 1 synchronous wheel 28 is coaxially fixed to the drive disk 11, the No. 2 synchronous wheel 29 is coaxially fixed to the transmission shaft 26, and the synchronous belt 31 is sleeved on the No. 1 synchronous wheel 28 and the No. 2 synchronous wheel 29.

[0054] When the reduction motor 27 is started, the reduction motor 27 drives the transmission shaft 26 to rotate, and the transmission shaft 26 synchronously drives the two second synchronous wheels 29 to rotate. Then, through the transmission action of the synchronous belt 31, the two first synchronous wheels 28 simultaneously drive the two drive discs 11 to rotate in the same direction.

[0055] To illustrate how each traction rope 8 is connected to the top of the flip stand 4, the following features are provided:

[0056] A horizontal roller 32 is formed at the bottom of the flip stand 4, and both ends of the roller 32 are rotatably connected to the movable base 1. Two symmetrical hanging rings 33 are fixed on the top of the flip stand 4. Each traction rope 8 extending to the flip stand 4 is fixedly connected to a connecting ring 34 at one end, and the connecting ring 34 is sleeved on the corresponding hanging ring 33.

[0057] One end of each traction rope 8 is connected to the flip stand 4 through the cooperation of the connecting ring 34 and the hanging ring 33. When the No. 1 rotating drum 7 unwinds the traction rope 8, the flip stand 4 will flip toward the slope by gravity. When the No. 1 rotating drum 7 rewinds the traction rope 8, the flip stand 4 will be pulled toward the supporting stand 2 by the traction rope 8.

[0058] In order to prevent the flip stand 4 from always exerting gravity traction on the two traction ropes 8 when not in use, the following features are provided:

[0059] The support stand 2 is formed with a No. 1 bracket 35 on one side facing the flip stand 4. A horizontal support plate 36 is fixed on the No. 1 bracket 35. A lifting lock frame is provided above the support plate 36. The lifting lock frame includes a flat plate 37 and two limit plates 38 (such as Figure 10As shown), the bottom of the flat plate 37 is formed with several limit pins 39 that pass vertically downward through the support plate 36. The lower end of each limit pin 39 is screwed with a limit nut 40 that contacts the support plate 36 upward. Each limit pin 39 is sleeved with a No. 3 spring 41. The two ends of the No. 3 spring 41 contact the flat plate 37 and the support plate 36 respectively. A downward pressing mechanism for driving the flat plate 37 to descend is provided above the flat plate 37. The two limit plates 38 are symmetrically arranged at the two ends of the flat plate 37, and each limit plate 38 is vertical. Two symmetrical support rods 42 are fixed to the side of the flip stand 4 facing the supporting stand 2. One end of each support rod 42 is formed with a horizontal limit rod 43, and the two limit rods 43 correspond to the two limit plates 38 respectively.

[0060] In the initial state, a plurality of No. 3 springs 41 drive the plate 37 to an upward state through elastic force. At this time, each limiting nut 40 will contact the supporting plate 36 upward to prevent the limiting pin 39 from sliding out of the supporting plate 36. When the plate 37 is in the upward state, each limiting rod 43 provided on one side of the flip stand 4 will contact the corresponding limiting plate 38 toward the side of the supporting stand 2 (such as Figure 10 As shown), the cooperation between the limit plate 38 and the limit rod 43 is used to limit the flip stand 4 from flipping toward the slope due to gravity. When not working, the force on the traction rope 8 is reduced, and the service life of the traction rope 8 is extended. When the flip stand 4 needs to be flipped toward the slope, the downward pressure mechanism applies downward pressure to the plate 37 to drive the plate 37 down. During this process, the plate 37 compresses each No. 3 spring 41, so that the No. 3 spring 41 generates elastic force. During the descent of the plate 37, the limit rod 43 slides on the corresponding limit plate 38. Then, when When the flat plate 37 descends to the point where the limit rod 43 passes over the top of the limit plate 38, the limit rod 43 loses the resistance of the limit plate 38. At this time, the flip stand 4 is no longer restricted by the limit plate 38, and the No. 1 rotating drum 7 can flip the flip stand 4 toward the slope by unwinding the traction rope 8. When the flip stand 4 flips back to reset, each limit rod 43 will pass over the flat plate 37. Thereafter, the downward pressure mechanism will stop applying pressure to the flat plate 37, and the flat plate 37 will be driven to rise by the elastic force of several No. 3 springs 41, and finally the limit rod 43 will again conflict with the rising limit plate 38.

[0061] In order to show the specific structure of the pressing mechanism, the following features are set:

[0062] The pressing mechanism includes a pressure block 44, a pull rope 45 and a second rotating drum 46. A second bracket 47 is provided above the first bracket 35 and is fixedly connected to the support frame 2. A guide wheel 48 is provided on the second bracket 47. The pressure block 44 is provided above the flat plate 37. The second rotating drum 46 is coaxially fixedly connected to the transmission shaft 26 (as shown in FIG. Figure 1As shown), the pull rope 45 is wound around the second rotating drum 46, one end of the pull rope 45 is fixedly connected to the second rotating drum 46, and the other end of the pull rope 45 is tilted downward to pass around the guide wheel 48 and then vertically downward to be fixedly connected to the top of the pressure block 44. The top of the support plate 36 is formed with a vertically upward support block 49.

[0063] When the reduction motor 27 is started, the reduction motor 27 drives the transmission shaft 26 to rotate. At this time, the No. 1 drum 7 will unwind the traction rope 8, and the No. 2 drum 46 will unwind the pull rope 45. When the pull rope 45 is unwound, the pressure block 44 will press down on the plate 37, thereby driving the plate 37 to overcome the elastic force of the No. 3 spring 41 and descend. When the plate 37 descends to the limit rod 43 and passes over the limit plate 38, the flip stand 4 is no longer restricted by the limit plate 38, and then the flip stand 4 can move toward the slope. Flipping, when the reduction motor 27 drives the transmission shaft 26 to rotate in the opposite direction, the No. 1 rotating drum 7 will reel in the traction rope 8, and the No. 2 rotating drum 46 will reel in the pull rope 45. The reeled traction rope 8 will pull the flip stand 4 toward the support stand 2. During this process, the limit rod 43 will pass over the plate 37 in the descending state. At the same time, the reeled pull rope 45 will drive the pressure block 44 to rise. Then, when the limit rod 43 passes over the plate 37, the plate 37 that loses pressure will be driven up by the elastic force of the No. 3 spring 41. Finally, the limit rod 43 will conflict with the rising limit plate 38 again, wherein the support block 49 provided on the support plate 36 is used to limit the descending stroke of the plate 37 to prevent the No. 3 spring 41 from being compressed to the limit and affecting its service life. While the No. 2 rotating drum 46 unwinds the pull rope 45, the No. 1 rotating drum 7 unwinds the traction rope 8. Then, when the plate 37 starts to descend until the limit rod 43 passes over the plate 37, the flip stand 4 will not flip over, but the traction rope 8 will continue to be unwound. The traction rope 8 between the frame 4 and the supporting frame 2 will be temporarily relaxed. Once the limit rod 43 passes over the flat plate 37, the flip frame 4 is no longer restricted by the limit plate 38. At this time, the flip frame 4 will immediately flip toward the slope. At this time, the traction rope 8 between the flip frame 4 and the supporting frame 2 will be straightened. In the process of processing the limit pin 39, the length of the limit pin 39 needs to be accurately determined to ensure that when the flip frame 4 flips toward the supporting frame 2, the flat plate 37 can rise after the limit rod 43 passes over the flat plate 37.

[0064] In order to prevent the drawstring 45 from becoming loose, the following features are provided:

[0065] A vertical mounting plate 50 is formed on one side of the support frame 2 facing the flip frame 4 , and a gravity wheel 51 is slidably provided on the mounting plate 50 . The sliding direction of the gravity wheel 51 is vertical, and the gravity wheel 51 presses downward on the pull rope 45 .

[0066] At this time, the gravity wheel 51 will press down the rope 45 unwound from the No. 2 drum 46 through gravity, and finally prevent the rope 45 between the pressure block 44 and the No. 2 drum 46 from becoming slack.

[0067] In order to show the specific structure of the translation drive mechanism, the following features are set:

[0068] The translation drive mechanism includes two chain drive members symmetrically arranged on both sides of the flip frame 4, each chain drive member includes two symmetrical transmission chains 52, and two symmetrical strip side plates 53 are formed on both sides of the flip frame 4. The length direction of each strip side plate 53 is consistent with the length direction of the flip frame 4, and sprockets 54 are rotatably provided at both ends of each strip side plate 53, and the two adjacent sprockets 54 are coaxially fixedly connected. Each transmission chain 52 is sleeved on the corresponding two sprockets 54, and a connecting plate 55 is fixed between the two adjacent transmission chains 52. The two sides of the drilling rig platform 6 are fixedly connected to the two connecting plates 55.

[0069] During actual use, each chain drive member is provided with a drive motor (not shown in the figure) fixedly connected to the flip stand 4. The drive motor is used to drive the corresponding sprocket 54 to rotate, and the two drive motors work synchronously. When the sprocket 54 rotates, the sprocket 54 will drive the corresponding transmission chain 52 to rotate, so that the two connecting plates 55 will synchronously drive the drilling rig platform 6 to translate along the length direction of the flip stand 4.

[0070] Working principle:

[0071] This device is used to assist in positioning anchor holes during slope reinforcement. The specific operation process is as follows: When not working, the No. 1 rotating drum 7 pulls the flip stand 4 through two traction ropes 8 to flip and gradually approach the support stand 2, and finally makes the flip stand 4 tilted (such as Figure 1 As shown), when working, the mobile base 1 is moved to the land beside the slope, and the flip stand 4 is made to face the slope. At this time, the flip stand 4 will tilt towards the slope (as shown in FIG. Figure 18As shown), in actual use, a feed drill (not shown in the figure) is installed on the drilling rig platform 6, and the forward direction of the feed drill is parallel to the length direction of the drilling rig platform 6. Thereafter, the rotary drive mechanism drives the No. 1 rotary drum 7 to rotate, and the No. 1 rotary drum 7 synchronously unwinds the two traction ropes 8, so that the flip frame 4 will turn to the slope due to gravity, and a number of distance sensors 5 provided on one side of the flip frame 4 will gradually approach the slope. During this process, each distance sensor 5 will monitor the distance to the slope in real time. Since the several distance sensors 5 are equidistantly distributed along the length direction of the flip frame 4, when the distances monitored by the several distance sensors 5 are close to each other, then the flip frame 4 is parallel to the slope (as shown in the figure). Figure 19 When the first drum 7 rotates and drives the flip frame 4 to flip toward the slope, the two traction ropes 8 will synchronously drive the balancing weight 3 to rise, and the balancing weight 3 is used to balance the weight of the flip frame 4 to prevent the flip frame 4 from being too heavy and overturning the first drum 7.
