Description

Technical Field

[0001] The present invention relates to the technical field of geotechnical engineering, and specifically relates to an auxiliary device for positioning drilling of anchor bolts and anchor cables. Background Technique

[0002] An anchor bolt is a tension member with one end anchored in a rock-soil mass and the other end connected to the surface of a structure or a rock-soil mass. Through the bonding force or frictional force between the anchor bolt and the rock-soil mass, the tensile force of the rock-soil mass is transmitted to a stable stratum, thereby improving the stability of the rock-soil mass and preventing its deformation and collapse.

[0003] An anchor cable is a tension rod made of high-strength steel such as steel strands and wire bundles. It is anchored in a deep and stable rock-soil mass through drilling, and the tensile force of the anchor cable is used to limit the deformation and displacement of the rock-soil mass. Anchor cables usually apply prestress and can more effectively control the deformation of the rock-soil mass and improve the stability of the structure.

[0004] The existing patent with the publication number CN118979495B in China discloses a slope anchor cable hole alignment auxiliary device and a construction quality guarantee method. However, the above patent still has the following defects: Firstly, the guiding component for the operation platform to move is directly installed on the slope. In the actual operation process, the surface of the slope cannot be completely flat. Therefore, when installing the guiding component, the guiding component will be skewed, ultimately affecting the advancing direction of the operation platform. If the surface of the slope is treated, the corresponding workload will be increased and the drilling efficiency will be reduced. Moreover, after the guiding component is installed, the weight of the operation platform will act on the slope, so it will cause damage to the slope, resulting in slope cracking and even landslides in rainy days. Secondly, when drilling holes on the slope, several evenly distributed holes need to be drilled on the entire slope. The above patent can only position and drill a small part of the entire slope. If the drilling position is changed, the guiding component needs to be removed and reinstalled after the position is changed, which will increase the work intensity and also waste a lot of time.

[0005] Therefore, in view of the above problems, it is necessary to provide an auxiliary device for positioning drilling of anchor bolts and anchor cables to solve them. Summary of the Invention

[0016] The beneficial effects of the present invention compared with the prior art are as follows: First, the drilling rig platform of the present device is arranged on the flipping vertical frame. When performing drilling positioning, the flipping vertical frame will flip to be parallel to the slope. Then, the feed drilling rig arranged on the drilling rig platform can directly move forward to drill the slope, and the flipping vertical frame does not contact the slope, so no pressure will be exerted on the slope, ultimately preventing the slope from being cracked and landslided due to pressure. Second, the flipping vertical frame of the present device is arranged on the moving base. During the actual process of drilling the slope, when all the holes in a certain area of the slope are drilled, the moving base can drive the flipping vertical frame to displace along the extension length of the slope. Then, the drilling rig platform arranged on the flipping vertical frame can drive the feed drilling rig to displace towards the area of the slope where the holes have not been drilled. Compared with the above-mentioned patent that needs to disassemble the guiding component to change the position, the present device does not need to perform any redundant disassembly work, shortening the working process and improving the drilling efficiency. Third, the present device controls the flipping of the flipping vertical frame by winding and unwinding the traction rope through the first rotating cylinder. When the first rotating cylinder stops moving, the first rotating cylinder can be locked by the self-locking mechanism of the present device, thereby ensuring that the flipping vertical frame is stable at the current position after stopping flipping. Fourthly, when not in operation, the flipping stand is matched with the lifting lock stand on the supporting stand through two limiting rods thereon, so as to lock the flipping stand on the supporting stand, thereby avoiding the pulling force of the flipping stand on the towing rope when not in operation, and thus prolonging the service life of the towing rope.

Specific implementation mode

[0019] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0020] Refer to Figures 1 to 19 An auxiliary device for positioning the drilling of anchor bolts and anchor cables shown in the figure, including a mobile base 1, a support stand 2 is provided on the mobile base 1, and a balance weight 3 that slides in the vertical direction is provided on the support stand 2 (as Figure 7As shown in the figure, a tilting support stand 4 is provided beside the support stand 2. The bottom of the tilting support stand 4 is hinged to the moving base 1. A plurality of distance sensors 5 are provided on the side of the tilting support stand 4 away from the support stand 2, and the plurality of distance sensors 5 are equidistantly distributed along the length direction of the tilting support stand 4. A drilling platform 6 and a translation driving mechanism are provided on the tilting support stand 4. The drilling platform 6 is slidably connected to the tilting support stand 4, and the length direction of the drilling platform 6 is perpendicular to the length direction of the tilting support stand 4. The translation driving mechanism is used to drive the drilling platform 6 to translate along the length direction of the tilting support stand 4. A self-locking traction assembly is provided at the top of the support stand 2. The self-locking traction assembly includes a first rotating cylinder 7, a rotation driving mechanism, two traction ropes 8 and two self-locking mechanisms. The first rotating cylinder 7 is horizontally rotatably connected to the top of the support stand 2. The two traction ropes 8 are symmetrically wound around the first rotating cylinder 7. One end of each traction rope 8 is vertically downwardly connected to the balance weight 3, and the other end of each traction rope 8 is obliquely downwardly connected to the top of the tilting support stand 4. The two self-locking mechanisms are respectively provided at both ends of the first rotating cylinder 7, and each self-locking mechanism is used to lock the first rotating cylinder 7. The rotation driving mechanism is provided beside the first rotating cylinder 7, and the rotation driving mechanism is used to drive the first rotating cylinder 7 to rotate.

[0021] This device is used for auxiliary positioning of the anchor rod drilling during slope reinforcement. The specific operation process is as follows. When not working, the first rotating cylinder 7 pulls the tilting support stand 4 to tilt and gradually approach the support stand 2 through the two traction ropes 8, and finally makes the tilting support stand 4 in an inclined state (as Figure 1 shown in the figure). When working, move the moving base 1 to the land beside the slope and make the tilting support stand 4 face the slope. At this time, the tilting support stand 4 will tilt towards the slope (as Figure 18 shown in the figure). In actual use, a feed drill (not shown in the figure) is installed on the drilling platform 6, and the advancing direction of the feed drill is parallel to the length direction of the drilling platform 6. Then the rotation driving mechanism drives the first rotating cylinder 7 to rotate, and the first rotating cylinder 7 synchronously pays out the two traction ropes 8. In this way, the tilting support stand 4 will turn towards the slope due to gravity, and a plurality of distance sensors 5 provided on one side of the tilting support stand 4 will gradually approach the slope. During this process, each distance sensor 5 will continuously monitor the distance from the slope. Since the plurality of distance sensors 5 are equidistantly distributed along the length direction of the tilting support stand 4, when the distances monitored by the plurality of distance sensors 5 approach the same value, then at this time the tilting support stand 4 is parallel to the slope (as Figure 19As shown in the figure, when the tipping support 4 is parallel to the slope, the feeding drill on the drill platform 6 will be perpendicular to the slope. Then, control the feeding drill to move forward directly to drill holes in the slope. When the first drum 7 winds and unwinds the two towing ropes 8 until the tipping support 4 stops tipping, the two self-locking mechanisms will lock the first drum 7 synchronously, thereby restricting the rotation of the first drum 7, and further ensuring that the tipping support 4 can be stable at the current position and will not tip by itself when it stops. When the first drum 7 rotates to drive the tipping support 4 to tip towards the slope, the two towing ropes 8 will synchronously drive the balance weight 3 to rise, and the balance weight 3 is used to balance the weight of the tipping support 4 to prevent the tipping support 4 from being too heavy and tipping over the first drum 7.

[0022] In order to show the specific structure of each self-locking mechanism, the following features are set: Each self-locking mechanism includes a turntable 9, a ratchet ring 10, a driving disk 11, two first locking blocks 12 and two second locking blocks 13. The turntable 9 is coaxially fixed to the first drum 7 (as Figure 13 shown in the figure). The ratchet ring 10 is fixed to the support stand 2, and the ratchet ring 10 and the turntable 9 are coaxial. A circle of first ratchets 14 and a circle of second ratchets 15 are formed on the inner ring of the ratchet ring 10, and the tooth directions of each first ratchet 14 and second ratchet 15 are opposite. Four strip-shaped chutes 16 are formed on one side of the turntable 9, and the four strip-shaped chutes 16 are evenly distributed along the circumferential direction of the turntable 9. The length direction of each strip-shaped chute 16 is consistent with the radial direction of the turntable 9. The two first locking blocks 12 are symmetrically slidably arranged in two of the strip-shaped chutes 16, and the two second locking blocks 13 are symmetrically slidably arranged in the other two strip-shaped chutes 16. Each first locking block 12 and second locking block 13 is elastically connected to the turntable 9. One end of each first locking block 12 is provided with a first pawl 17 that cooperates with the first ratchet 14, and one end of each second locking block 13 is provided with a second pawl 18 that cooperates with the second ratchet 15. The driving disk 11 is coaxially connected to the turntable 9, and an expansion and contraction driving member for respectively driving the first locking block 12 and the second locking block 13 to expand and contract is arranged between the driving disk 11 and the turntable 9. Each driving disk 11 is connected to the rotary driving mechanism.

[0023] When the driving disk 11 does not rotate, each first locking block 12 and second locking block 13 will extend towards the ratchet ring 10 along the corresponding strip-shaped chute 16 by elasticity. At this time, the first pawl 17 on the first locking block 12 will engage between two adjacent first ratchets 14, and the second pawl 18 on the second locking block 13 will engage between two adjacent second ratchets 15 (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 be separated 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 the 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 ratchet teeth 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 groove 16 through elasticity, and finally the turntable 9 will be locked again.

[0024] In order to show the specific structure of the telescopic drive, the following features are set: A rotating shaft 19 is coaxially formed on the side of each rotating disk 9 away from the No. 1 rotating cylinder 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 are respectively in 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 are respectively in conflict with the No. 2 locking block 13 and the rotating shaft 19. Each telescopic driving member includes two No. 1 inclined surface blocks 22, two No. 2 inclined surface blocks 23, two No. 1 driving pins 24 and two No. 2 driving pins 25. The two No. 1 inclined surface blocks 22 are respectively connected to the two No. 1 locking blocks 12, and the two No. 2 inclined surface blocks 23 are respectively connected to the two No. 2 locking blocks 13, and 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 in the figure, 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 slide groove 16.

[0025] When the driving disk 11 stops rotating, each of the No. 1 driving pin 24 and the No. 2 driving pin 25 is located at the middle position of the corresponding strip-shaped slide groove 16 (such asFigure 14 As shown in the figure, at this time, the first driving pin 24 does not contact the first inclined plane block 22, and the second driving pin 25 does not contact the second inclined plane block 23. Then, the first spring 20 will drive the first locking block 12 to extend through its elastic force, and the second spring 21 will drive the second locking block 13 to extend through its elastic force. Finally, each first pawl 17 will engage between two adjacent first ratchet teeth 14, and each second pawl 18 will engage between two adjacent second ratchet teeth 15. At this time, the turntable 9 is locked by the first locking block 12 and the second locking block 13 and cannot rotate. When the rotary driving mechanism drives the driving disk 11 to rotate counterclockwise, the driving disk 11 will synchronously drive each first driving pin 24 and second driving pin 25 to revolve. During this process, the second driving pin 25 will directly contact the corresponding strip-shaped chute 16, and the first driving pin 24 will first contact the first inclined plane block 22. At this time, the first locking block 12 will retract due to the cooperation between the first inclined plane block 22 and the first driving pin 24. When the first locking block 12 retracts, the first pawl 17 will separate from the first ratchet tooth 14. After the first pawl 17 separates from the first ratchet tooth 14, the first driving pin 24 will contact the corresponding strip-shaped chute 16. Finally, the driving disk 11 will drive the turntable 9 to rotate through the first driving pin 24 and the second driving pin 25 to realize the unwinding of the traction rope 8. When the flipping vertical frame 4 flips to be parallel to the slope, the driving disk 11 stops rotating. At this time, the first locking block 12 and the second locking block 13 respectively extend again through the elastic forces of the first spring 20 and the second spring 21. In this way, the turntable 9 will be locked again. When it is necessary to drive the flipping vertical frame 4 to reset, the rotary driving mechanism will drive the driving disk 11 to rotate in the reverse direction. During this process, the second driving pin 25 will contact the second inclined plane block 23, so as to realize the retraction of the second locking block 13, and further separate the second pawl 18 from the adjacent second ratchet tooth 15. And the first pawl 17 will slide between several first ratchet teeth 14 through its inclined plane and the elasticity of the first spring 20. To sum up, no matter whether the driving disk 11 rotates forward or backward, the first rotating cylinder 7 will be driven by the driving disk 11 to rotate through the turntable 9. When the driving disk 11 stops, the turntable 9 will immediately be locked by the first locking block 12 and the second locking block 13, and finally realize the self-locking of the first rotating cylinder 7.

[0026] In order to show the specific structure of the rotary driving mechanism, the following features are set: The rotation drive mechanism includes a transmission shaft 26, a reduction motor 27 and two synchronous transmission components. The transmission shaft 26 is rotatably arranged at the top of the support upright 2, and the axial direction of the transmission shaft 26 is parallel to the axial direction of the first rotating cylinder 7. The reduction motor 27 is horizontally fixed at the top of the support upright 2, and the output end of the reduction motor 27 is coaxially fixed to the transmission shaft 26. The two synchronous transmission components are respectively arranged at both ends of the first rotating cylinder 7. Each synchronous transmission component includes a first synchronous pulley 28, a second synchronous pulley 29 and a synchronous belt 31. The first synchronous pulley 28 is coaxially fixed to the driving disc 11, the second synchronous pulley 29 is coaxially fixed to the transmission shaft 26, and the synchronous belt 31 is sleeved on the first synchronous pulley 28 and the second synchronous pulley 29.

[0027] After the reduction motor 27 is started, the reduction motor 27 will drive the transmission shaft 26 to rotate. Thus, the transmission shaft 26 will synchronously drive the two second synchronous pulleys 29 to rotate. Then, through the transmission of the synchronous belt 31, the two first synchronous pulleys 28 will simultaneously drive the two driving discs 11 to rotate in the same direction.

[0028] In order to show how each towing rope 8 is connected to the top of the tipping upright 4, the following features are provided: A horizontal roller 32 is formed at the bottom of the tipping upright 4. Both ends of the roller 32 are rotatably connected to the moving base 1. Two symmetrically arranged lifting rings 33 are fixedly provided at the top of the tipping upright 4. One end of each towing rope 8 extending towards the tipping upright 4 is fixedly connected with a connecting ring 34, and the connecting ring 34 is sleeved on the corresponding lifting ring 33.

[0029] One end of each towing rope 8 is connected to the tipping upright 4 through the cooperation of the connecting ring 34 and the lifting ring 33. When the first rotating cylinder 7 pays out the towing rope 8, the tipping upright 4 will automatically tip towards the slope by gravity. When the first rotating cylinder 7 winds up the towing rope 8, the tipping upright 4 will be pulled towards the support upright 2 by the towing rope 8.

[0030] When not in operation, in order to prevent the tipping upright 4 from always applying a gravity traction to the two towing ropes 8, the following features are provided: A first bracket 35 is formed on the side of the support upright 2 facing the tipping upright 4. A horizontal support plate 36 is fixedly provided on the first bracket 35. An elevating lock frame is arranged above the support plate 36. The elevating lock frame includes a flat plate 37 and two limit plates 38 (as Figure 10As shown in the figure, several vertical limit pins 39 are formed at the bottom of the flat plate 37 and pass through the support plate 36 vertically downward. A limit nut 40 that rotates upward and abuts against the support plate 36 is provided at the lower end of each limit pin 39. A third spring 41 is sleeved on each limit pin 39. The two ends of the third spring 41 abut against the flat plate 37 and the support plate 36 respectively. An upper pressing mechanism for driving the flat plate 37 to descend is provided above the flat plate 37. Two limit plates 38 are symmetrically arranged at both ends of the flat plate 37 respectively. Each limit plate 38 is vertical. Two symmetrically arranged support rods 42 are fixedly provided on the side of the flipping upright frame 4 facing the support upright frame 2. A horizontal limit rod 43 is formed at one end of each support rod 42. The two limit rods 43 correspond to the two limit plates 38 respectively.

[0031] In the initial state, several third springs 41 drive the flat plate 37 to be in the ascending state through elastic force. At this time, each limit nut 40 will abut against the support plate 36 upward to prevent the limit pin 39 from sliding out of the support plate 36. When the flat plate 37 is in the ascending state, each limit rod 43 arranged on one side of the flipping upright frame 4 will abut against the side of the corresponding limit plate 38 facing the support upright frame 2 (as Figure 10 shown), so as to limit the flipping of the flipping upright frame 4 due to gravity by the cooperation of the limit plate 38 and the limit rod 43. Then when not working, the force on the towing rope 8 is reduced, and the service life of the towing rope 8 is prolonged. When it is necessary to flip the flipping upright frame 4 towards the slope, the upper pressing mechanism will apply a downward pressure to the flat plate 37 to drive the flat plate 37 to descend. During this process, the flat plate 37 will compress each third spring 41 to make the third spring 41 generate elastic force. During the descent of the flat plate 37, the limit rod 43 will slide on the corresponding limit plate 38. Then when the flat plate 37 descends to the point where the limit rod 43 crosses the top of the limit plate 38, the limit rod 43 loses the abutment of the limit plate 38. At this time, the flipping upright frame 4 is no longer restricted by the limit plate 38. Then the first reel 7 can release the towing rope 8 to make the flipping upright frame 4 flip towards the slope. When the flipping upright frame 4 flips in the reverse direction for resetting, each limit rod 43 will cross the flat plate 37. After that, the upper pressing mechanism will stop pressing the flat plate 37. In this way, the flat plate 37 will be driven to rise by the elastic force of several third springs 41. Finally, the limit rod 43 will abut against the risen limit plate 38 again.

[0032] In order to show the specific structure of the upper pressing mechanism, the following features are set: The upper pressing mechanism includes a pressing block 44, a pulling rope 45 and a second reel 46. A second bracket 47 fixedly connected to the support upright frame 2 is provided above the first bracket 35. A guide wheel 48 is rotatably provided on the second bracket 47. The pressing block 44 is provided above the flat plate 37. The second reel 46 is coaxially fixedly connected to the transmission shaft 26 (as Figure 1As shown, the pulling rope 45 is wound around the second rotating cylinder 46. One end of the pulling rope 45 is fixedly connected to the second rotating cylinder 46, and the other end of the pulling rope 45 obliquely downward bypasses the guide pulley 48 and is vertically downward fixedly connected to the top of the pressing block 44. A vertically upward supporting block 49 is formed on the top of the supporting plate 36.

[0033] When the reduction motor 27 is started, the reduction motor 27 will drive the transmission shaft 26 to rotate. At this time, the first rotating cylinder 7 will unwind the traction rope 8, and the second rotating cylinder 46 will unwind the pulling rope 45. When the pulling rope 45 is unwound, the pressing block 44 will press downward on the flat plate 37, thereby driving the flat plate 37 to descend against the elastic force of the third spring 41. When the flat plate 37 descends until the limiting rod 43 crosses the limiting plate 38, the flipping upright frame 4 is no longer restricted by the limiting plate 38. Then, after that, the flipping upright frame 4 can flip towards the slope. When the reduction motor 27 drives the transmission shaft 26 to rotate in the reverse direction, the first rotating cylinder 7 will wind up the traction rope 8, and the second rotating cylinder 46 will wind up the pulling rope 45. The winding traction rope 8 will pull the flipping upright frame 4 towards the supporting upright frame 2. During this process, the limiting rod 43 will cross the flat plate 37 in the descending state. At the same time, the winding pulling rope 45 will drive the pressing block 44 to rise. Then, when the limiting rod 43 crosses the flat plate 37, the flat plate 37 that loses pressure will be driven to rise by the elastic force of the third spring 41. Finally, the limiting rod 43 will again abut against the risen limiting plate 38. Among them, the supporting block 49 provided on the supporting plate 36 is used to limit the descending stroke of the flat plate 37 to prevent the third spring 41 from being compressed to the limit and affecting its service life. While the second rotating cylinder 46 unwinds the pulling rope 45, the first rotating cylinder 7 will unwind the traction rope 8. Then, during the process from when the flat plate 37 starts to descend until the limiting rod 43 crosses the flat plate 37, the flipping upright frame 4 will not flip, but the traction rope 8 will continue to be unwound. At this time, the traction rope 8 between the flipping upright frame 4 and the supporting upright frame 2 will be briefly slack. Once the limiting rod 43 crosses the flat plate 37, the flipping upright frame 4 is no longer restricted by the limiting plate 38. At this time, the flipping upright frame 4 will immediately flip towards the slope. At this time, the traction rope 8 between the flipping upright frame 4 and the supporting upright frame 2 will be straightened. During the process of machining the limiting pin 39, it is necessary to accurately limit the length of the limiting pin 39 to ensure that when the flipping upright frame 4 flips towards the supporting upright frame 2, the flat plate 37 can rise after the limiting rod 43 crosses the flat plate 37.

[0034] In order to prevent the pulling rope 45 from becoming slack, the following features are provided: On the side of the supporting upright frame 2 facing the flipping upright frame 4, a vertical mounting plate 50 is formed. 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 pulling rope 45.

[0035] The gravity of the gravity wheel 51 is much smaller than the gravity of the pressure block 44. When the No. 2 rotating drum 46 reels the pull rope 45, one end of the pull rope 45 will drive the pressure block 44 to rise. At the same time, the gravity wheel 51 will be driven to rise by the pull rope 45, and when the No. 2 rotating drum 46 unwinds the pull rope 45, the pressure block 44 will fall due to gravity. In this process, the gravity wheel 51 will also fall due to gravity. When the pressure block 44 falls to the point where the flat plate 37 conflicts with the support block 49, the pressure block 44 no longer falls. At this time, the flip stand 4 may not have flipped to be parallel to the slope, so the transmission shaft 26 will continue to rotate until the traction rope 8 can continue to be unwound. When the transmission shaft 26 continues to rotate, the No. 2 rotating drum 46 will continue to unwind the pull rope 45 at the same time. At this time, the gravity wheel 51 will press down the pull rope 45 unwound from the No. 2 rotating drum 46 through gravity, and finally prevent the pull rope 45 between the pressure block 44 and the No. 2 rotating drum 46 from becoming loose.

[0036] In order to show the specific structure of the translation drive mechanism, the following features are set: The translation drive mechanism includes two chain drive members which are 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 panels 53 are formed on both sides of the flip frame 4. The length direction of each strip side panel 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 panel 53, and 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 fixedly provided 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 respectively.

[0037] In actual use, each chain drive member is provided with a drive motor (not shown in the figure) fixedly connected to the flip frame 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 platform 6 to translate along the length direction of the flip frame 4.

[0038] Working principle: This device is used to assist in positioning anchor holes during slope reinforcement. The specific operation process is as follows: When not working, the first rotating drum 7 pulls the flip frame 4 through two traction ropes 8 to flip and gradually approach the supporting frame 2, and finally makes the flip frame 4 tilted (such as Figure 1 As shown in FIG. 1 ), 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 be tilted toward the slope (as shown in FIG. 1 ). Figure 18As shown in the figure, during actual use, a feed drill (not shown in the figure) is installed on the drill rig platform 6, and the forward direction of the feed drill is parallel to the length direction of the drill rig platform 6. Then, the rotation drive mechanism drives the first drum 7 to rotate, and the first drum 7 pays out the two traction ropes 8 synchronously. In this way, the tipping support 4 will turn towards the slope due to gravity, and several distance sensors 5 provided on one side of the tipping support 4 will gradually approach the slope. During this process, each distance sensor 5 will monitor the distance from the slope in real time. Since several distance sensors 5 are evenly distributed along the length direction of the tipping support 4, when the distances detected by several distance sensors 5 approach the same, then at this time the tipping support 4 is parallel to the slope (as Figure 19 shown). When the tipping support 4 is parallel to the slope, the feed drill installed on the drill rig platform 6 will be perpendicular to the slope. Then, control the feed drill to move forward directly to drill holes in the slope. When the first drum 7 winds and unwinds the two traction ropes 8 until the tipping support 4 stops tipping, the two self-locking mechanisms will lock the first drum 7 synchronously, thereby restricting the rotation of the first drum 7, and further ensuring that the tipping support 4 can be stable at the current position and will not tip by itself when it stops. When the first drum 7 rotates to drive the tipping support 4 to tip towards the slope, the two traction ropes 8 will synchronously drive the balance weight 3 to rise, and the balance weight 3 is used to balance the weight of the tipping support 4 to prevent the tipping support 4 from being too heavy and overturning the first drum 7.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
