Description

Technical Field

[0001] This invention relates to the field of anchor drilling technology, specifically a high-stability anchor drilling machine that integrates drilling and anchoring. Background Technology

[0002] The tunneling and anchoring machine is a large coal mining equipment that integrates cutting, walking, anchoring, and temporary support. It can meet the work requirements of parallel tunneling and anchoring operations. That is, while performing cutting operations, the tunneling and anchoring machine can complete the anchoring support of the top and side walls. In order to realize the anchoring support operation of coal mine roadways, the tunneling and anchoring machine is equipped with multiple anchor drilling rigs.

[0003] Anchor bolt drilling rigs first drill holes in the rock or soil layer and then insert anchor bolts into the rock or soil layer to improve the stability and safety of the rock and soil and prevent disasters such as landslides and collapses. However, current anchor bolt drilling rigs often encounter hard rocks during drilling operations. At this time, the drill rod will be subject to greater resistance. If the drill rod is too long, it is easy to bend and break, resulting in the drill falling off or even the borehole being scrapped. This increases the construction period and production costs and reduces the efficiency of safe coal mining. Summary of the Invention

[0027] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0028] The present invention provides the following embodiments.

[0029] Example 1: This embodiment of the invention provides a high-stability anchor drilling rig with integrated tunneling and anchoring capabilities, such as... Figures 1-3 As shown, the system includes a base 1, with a tunneling and anchoring machine connected to the lower end of the base 1. A hydraulic cylinder 12 and a stabilizing guide mechanism are installed on the upper end of the base 1. The hydraulic cylinder 12 is connected to the stabilizing guide mechanism, which is connected to the drilling mechanism. A hydraulic cylinder 2 is installed on the lower end of the base 1 and is fixedly connected to a support plate 2. A support opening 7 is provided on the upper end of the support plate 2. Guide shafts 6 are symmetrically provided on the left and right sides of the end of the support plate 2 near the base 1, and the guide shafts 6 are slidably connected to the base 1.

[0030] The working principle of the above technical solution is as follows:

[0031] The lower end of the base 1 is connected to the integrated tunneling and anchoring machine. The angle of the base 1 on the integrated tunneling and anchoring machine can be adjusted, thereby adjusting the direction of the drill rod of the drilling mechanism. During anchor bolting operations, firstly, the hydraulic cylinder 2 is controlled to extend the support plate 2 to support the roadway. Then, the drilling mechanism is controlled to rotate the drill rod. When the drilling mechanism starts drilling, the stabilizing guide mechanism is used to drive the drilling mechanism to feed and to assist in positioning the middle of the drill rod, improving the stability of the drill rod during the feeding process and preventing the drill rod from bending and breaking when it is too long and encounters great resistance. This solves the problem that current anchor bolting rigs often encounter hard rock during drilling operations. At this point, the drill rod will encounter significant resistance. If the drill rod is too long, it is prone to bending and breakage, leading to drill bit loss or even borehole failure. This increases the construction cycle and production costs, and reduces the efficiency of safe coal mining. After the drill rod has been fed a certain distance and the length of the drill rod exposed to the outside has shortened, the stabilizing guide mechanism automatically releases the drill rod and drives the remaining drill rod to complete the feeding step. When the drill rod is retracted after drilling is completed, the drilling mechanism reverses to retrieve the drill rod. Finally, the anchor bolt is installed, and the hydraulic cylinder 2 drives the support plate 2 to retract, and the next anchor bolt operation is carried out. The sliding of the guide shaft 6 and the base 1 guides the movement of the support plate 2.

[0032] Example 2: Based on Example 1, such as Figures 1-5 As shown, the stabilizing guide mechanism includes guide rods 5 symmetrically arranged on the left and right sides of the upper end of the base 1, fixed plates 3 symmetrically arranged at the front and rear ends of the guide rods 5, guide rods 5 slidably connected to guide blocks 9, guide blocks 9 symmetrically arranged on the left and right sides of the lower end of the mounting plate 8, the lower middle part of the mounting plate 8 is fixedly connected to the fixed plate 4 10, the lower end of the fixed plate 4 10 away from the mounting plate 8 is fixedly connected to the sliding plate 13, the upper end of the fixed plate 4 10 away from the mounting plate 8 is fixedly connected to the clamping plate 23, the sliding plate 13 is slidably arranged on the upper end of the base 1, the sliding plate 13 is fixedly connected to the movable section of the hydraulic cylinder 12, and the fixed section of the hydraulic cylinder 12 is fixedly arranged on the upper end of the base 1.

[0033] The stabilizing guide mechanism also includes a stabilizing plate 11, which is in corresponding contact with the clamping plate 23. Stabilizing blocks 14 are symmetrically arranged on the left and right sides of the lower end of the stabilizing plate 11. The stabilizing blocks 14 are slidably arranged on the upper end of the base 1. The interior of the stabilizing blocks 14 is provided with a cavity. The rear end of the cavity is provided with a cover plate 47. The cover plate 47 is slidably connected to the sliding block 45. The sliding block 45 is fixedly connected to the connecting block 1 44. Several contact posts 1 are arranged in an array on the connecting block 1 44. A spring 1 46 is fixedly arranged between the connecting block 1 44 and the cover plate 47. The side of the sliding block 45 away from the connecting block 1 44 is fixedly connected to the mating block 1 48. The inclined section of the mating block 1 48 is slidably connected to the inclined section of the mating block 2 49. The mating block 2 49 passes through the side end of the cavity and is correspondingly mated to the groove of the sliding plate 13.

[0034] The upper left and right sides of the base 1 are symmetrically provided with fixing blocks 15. The front end of the fixing blocks 15 is fixedly connected to the connecting blocks 2 16. Several contact posts 2 are arranged in an array on the connecting blocks 2 16. The connecting blocks 1 44 and the connecting blocks 2 16 are correspondingly arranged, and the several contact posts 1 and several contact posts 2 are in contact with each other.

[0035] The working principle of the above technical solution is as follows:

[0036] When hydraulic cylinder 12 extends, it drives sliding plate 13 to slide along the upper end of base 1. Sliding plate 13 drives mounting plate 8 to move via fixed plate 4 10. When mounting plate 8 moves, it drives guide block 9 to move. Guide block 9 slides along guide rod 5. When sliding plate 13 slides, it also drives stabilizing block 14 to move. Stabilizing block 14 drives stabilizing plate 11 and mounting plate 8 to move synchronously. Stabilizing block 14 also drives connecting block 44 to move. After connecting block 44 and connecting block 16 make corresponding contact, several contact posts 1 on connecting block 44 and several contact posts 2 on connecting block 16 make corresponding contact. Several contact posts 1 and several contact posts 2 are like brushes, which can increase the friction after connecting block 44 and connecting block 16 are connected, so that connecting block 44 requires a larger force to move away from connecting block 16. After the connecting block 44 can no longer move with the stabilizing block 14, the connecting block 44 moves towards the cavity. The connecting block 44 drives the sliding block 45 to slide along the cover plate 47. The spring 46 is compressed, and the sliding block 45 drives the mating block 48 to move forward. The mating block 48 drives the mating block 49 to disengage from the slot. At this time, there is no longer a connection between the sliding plate 13 and the stabilizing block 14. As the hydraulic cylinder 12 extends and retracts, it drives the sliding plate 13 to move. The stabilizing block 14 stops moving under the limiting action of the connecting block 44, so that the stabilizing block 14 and the stabilizing plate 11 stop moving. At this time, the sliding plate 13 drives the mounting plate 8 to move independently. The friction between the stabilizing block 14 and the base 1 is greater than the maximum elastic force of the spring 46. Therefore, even after the spring 46 is compressed, it cannot push the stabilizing block 14 to slide on the base 1.

[0037] When hydraulic cylinder 12 retracts, it drives sliding plate 13 to slide in the opposite direction along the upper end of base 1. Sliding plate 13 drives mounting plate 8 to move in the opposite direction through fixing plate 4 10. Sliding plate 13 moves in the opposite direction to the corresponding position of stabilizing block 14. At this time, the slot on sliding plate 13 is set to correspond with mating block 2 49, and the locking plate 23 is in contact with stabilizing plate 11. At this time, fixing plate 4 10 will drive stabilizing plate 11 to move through locking plate 23. Stabilizing plate 11 drives stabilizing block 14 to move. When stabilizing block 14 moves, mating block 2 49 connected to it is always in contact with the slot. In this process, due to the mutual contact of several contact posts 1 and several contact posts 2, connecting block 1 44 and connecting block 2 16 are not separated. At the same time, under the elastic action of spring 1 46, sliding block 45 and cover plate 47 slide in opposite directions. At this time, cooperating block 2 49 returns to its original position and is inserted into the slot, completing the connection between sliding plate 13 and stabilizing block 14. Until sliding block 45 can no longer move relative to cover plate 47, stabilizing block 14 drives connecting block 1 44 and connecting block 2 16 to separate, and stabilizing plate 11 returns to its original position along with sliding plate 13.

[0038] Example 3: Based on Example 2, such as Figures 1-5As shown, the end of the mating block 48 distributed on the right side away from the cover plate 47 is fixedly connected to the mating block 50. The inclined section of the mating block 50 is slidably connected to the inclined section of the mating block 51. The mating block 51 penetrates the upper end of the cavity and enters the interior of the stabilizing plate 11 and is fixedly connected to the rack. The rack meshes with the gear ring 1. The gear ring 1 is fixedly connected to the rotating ring 41. The rotating ring 41 is rotatably set at the front end of the stabilizing plate 11. The rear end of the stabilizing plate 11 is rotatably provided with a stabilizing sleeve 52. The front and rear ends of the stabilizing sleeve 52 are provided with stabilizing holes 22. The front part of the stabilizing sleeve 52 is correspondingly set in the inner ring of the rotating ring 41. The stabilizing sleeve 52 is evenly distributed with a number of positioning rods 43 in the circumferential direction. The number of positioning rods 43 are staggered in the front-rear direction. The number of positioning rods 43 are slidably connected with a number of guide arc blocks 42. The number of guide arc blocks 42 are evenly distributed in the circumferential direction in the inner ring of the rotating ring 41.

[0039] The working principle of the above technical solution is as follows:

[0040] In the initial state, when the hydraulic cylinder 12 is retracted to its shortest position, there is a certain gap between the stabilizing plate 11 and the mounting plate 8. The stabilizing hole 22 allows the drill rod to pass through, thus aligning the stabilizing hole 22 with the middle area of ​​the drill rod in the initial state. Several positioning rods 43 arranged circumferentially on the stabilizing sleeve 52 can contact and support the middle cylindrical section of the drill rod. At this time, the protruding section of the guide arc block 42 contacts the positioning rod 43. When the drill rod rotates, it can drive the stabilizing sleeve 52 to rotate through the positioning rod 43. When the stabilizing sleeve 52 and the positioning rod 43 rotate, the positioning rod 43 continues to slide towards the protruding section of the guide arc block 42. Because the positioning rod 43 and the drill rod... Since the rod contact cannot move towards the drill rod, the positioning rod 43 pushes the guide arc block 42 and its connected rotating ring 41 to rotate. At this time, the stabilizing sleeve 52 and the rotating ring 41 rotate synchronously with the drill rod, and the stabilizing sleeve 52 can move with the stabilizing plate 11. When the stabilizing plate 11 moves synchronously with the mounting plate 8, the stabilizing sleeve 52 can move synchronously with the drill rod. This allows the stabilizing sleeve 52 to rotate synchronously with the drill rod when the drill rod starts drilling, supporting the middle area of ​​the drill rod and improving the stability of the drill rod during the rotation feeding process. This prevents the drill rod head from being subjected to excessive force, which could cause the drill rod to bend or even break.

[0041] When the drill rod is fed to a certain distance and needs to be positioned in front of the stabilizing hole 22 for drilling, connecting block 1 44 and connecting block 2 16 make corresponding contact, and the stabilizing plate 11 stops moving. As connecting block 1 44 drives sliding block 45 to slide along cover plate 47, sliding block 45 drives mating block 3 50 to move. Mating block 3 50 pushes mating block 4 51 to move upward. Mating block 4 51 drives rack to move upward and mesh with gear ring 1. The rack pushes gear ring 1 to rotate, and the rotation speed of gear ring 1 is greater than that of the drill rod. The speed is such that the gear ring drives the rotating ring 41 to rotate. The protruding section of the guide arc block 42 in the rotating ring 41 gradually disengages from the positioning rod 43, causing the positioning rod 43 to move away from the drill rod. The positioning rod 43 disengages from the cylindrical section of the drill rod. At this time, the stabilizing sleeve 52 stops rotating and moving. The front part of the drill rod can pass through the stabilizing hole 22 to continue drilling. The stabilizing sleeve 52 and the positioning rod 43 connected to it are designed to prevent the drill rod from being too long and bending or even breaking during its rotation and feeding process.

[0042] While the second engagement block 49 returns to its original position and is inserted into the slot, the fourth engagement block 51 drives the rack to return to its original position. The rack first drives the first rotating ring 41 to return to its original position until the rack and the first ring disengage. At this time, the positioning rod 43 re-engages with the drill rod. When disassembling the drill rod, control the rotation of the stabilizing sleeve 52 so that the protruding section of the guide arc block 42 disengages from the positioning rod 43.

[0043] Example 4: Based on Example 2, such as Figures 1-8 As shown, the drilling mechanism includes a hydraulic motor 4 fixedly mounted on the front right side of the mounting plate 8. The rotating shaft of the hydraulic motor 4 passes through the mounting plate 8 and is fixedly connected to the gear 17. The gear 17 meshes with the gear ring 18. The gear ring 18 is fixedly connected to the rotating sleeve 19. The rotating sleeve 19 is rotatably connected to the rear end of the mounting plate 8. The rotating sleeve 19 has a working port 24 inside. Several positioning arc blocks 25 are evenly distributed in the circumference of the working port 24. The positioning arc blocks 25 are in corresponding contact with the pushing block 26. The pushing block 26 is fixedly connected to the connecting block 27. Several springs 28 are fixedly provided between the connecting block 27 and the drill bit 20. The drill bit 20 has a fixing hole 29 inside. Several fixing blocks 21 are evenly distributed in the circumference of the fixing hole 29. Several fixing blocks 21 are fixedly connected to the pushing block 26 that passes through the side end of the drill bit 20.

[0044] The drill bit 20 passes through the mounting plate 8 and is fixedly connected to the gear ring 30. Several limiting rods 35 are provided between the adjacent teeth of the gear ring 30. The limiting rods 35 are fixedly connected to the rotating shaft 36. The rotating shaft 36 is rotatably set in the side opening groove 34 of the mounting block 31. The upper and lower sides of the end of the limiting rod 35 away from the gear ring 30 are symmetrically provided with inclined blocks 37. The inclined section of the inclined block 37 is in contact with the inclined section of the inclined block 38. The inclined blocks 38 are symmetrically set on the upper and lower sides of the fixing plate 53. The end of the fixing plate 53 away from the inclined block 38 is fixedly connected to the spring 39. The spring 39 is fixedly connected to the fixing plate 54. The fixing plate 53 and the fixing plate 54 are both slidably set in the side opening groove 34 of the mounting block 31.

[0045] A push rod 40 is movably provided in mounting block 1 31. The push rod 40 is fixedly connected to the fixing plate 2 54. The threaded section of the push rod 40 is threadedly connected to the threaded sleeve 33. The threaded sleeve 33 is rotatably set in mounting block 2 32. Both mounting block 1 31 and mounting block 2 32 are fixedly set at the front end of mounting plate 8.

[0046] The working principle of the above technical solution is as follows:

[0047] When fixing the drill rod, the tail end of the drill rod is inserted into the fixing hole 29. Then, the hydraulic motor 4 is controlled to work. The rotating shaft of the hydraulic motor 4 drives the gear 17 to rotate, the gear 17 drives the gear ring 18 to rotate, the gear ring 18 drives the rotating sleeve 19 to rotate, and the rotating sleeve 19 drives the positioning arc block 25 to rotate. After the positioning arc block 25 contacts the pushing block 26, it pushes the pushing block 26 to move towards the drill bit 20. The pushing block 26 drives the connecting block 27 to move, and the spring 28 is compressed. The pushing block 26 drives the fixing block 21 to clamp and fix the tail end of the drill rod. After the drill rod is clamped and fixed, as the rotating sleeve 19 continues to rotate, the rotating sleeve 19 drives the pushing block 26 to rotate through the positioning arc block 25. The pushing block 26 can no longer move towards the drill bit 20, and it begins to drive the drill bit 20 to rotate. The drill bit 20 drives the drill rod to rotate, causing the drill rod to start rotating. If the drill rod is rotated in the opposite direction, the hydraulic motor 4 is controlled to work in the opposite direction, which drives the rotating sleeve 19 to rotate in the opposite direction through the gear 17 and the gear ring 18. The left and right sides of the positioning arc block 25 are both arc segments, so the rotating sleeve 19 will push the push block 26 towards the drill bit 20 in both forward and reverse rotation, and then drive the drill bit 20 to rotate. If the drill rod is to be disassembled, the rotating sleeve 19 is controlled to rotate in the opposite direction of the current working rotation by a certain angle, so that the protruding section of the positioning arc block 25 is disengaged from the push block 26. During this process, under the elastic action of the spring 28, the push block 26 will be driven to move away from the drill bit 20. The push block 26 drives the fixing block 21 to disengage from the drill rod, and then the drill rod can be removed from the fixing hole 29.

[0048] When drill bit 20 rotates, it drives gear ring 30 to rotate. The serrated teeth of gear ring 30 drive limit rod 35 to rotate. Limit rod 35 rotates around rotating shaft 36. When limit rod 35 rotates, it drives tilting block 37 to rotate. The tilted section of tilting block 37 contacts the tilted section of tilting block 38, pushing tilting block 38 away from limit rod 35. Tilting block 38 drives fixed plate 53 to move. Fixed plate 53 compresses spring 39 until limit rod 35 disengages from the serrated teeth of gear ring 30. Then, under the elastic action of spring 39, fixed plate 53 is pushed... The fixed plate 53, via the tilting block 38, drives the tilting block 37 to return to its original position. The tilting block 37 then drives the limiting rod 35 to return to its original position, so that the limiting rod 35 is once again positioned between the adjacent serrations of the gear ring 30. There are two or more limiting rods 35. By setting at least two limiting rods 35 at different angles, even if one limiting rod 35 disengages from the serrations of the gear ring 30, the remaining limiting rods 35 can still contact the serrations of the gear ring 30. This ensures that the gear ring 30 always needs to contact the limiting rod 35 when rotating, meaning that the rotation of the gear ring 30 needs to overcome the resistance of the spring 39. The elastic force required to overcome the spring 39 is greater as the compression distance of the spring 39 increases. Therefore, the elastic force required to overcome the spring 39 when the gear ring 30 rotates is variable. By rotating the threaded sleeve 33, the push rod 40 can be moved towards the gear ring 30. The push rod 40 causes the fixed plate 2 54 to slide, compressing the spring 39. This results in a greater force required to move the fixed plate 1 53, which in turn requires a greater force to rotate the limit rod 35. This changes the force required to rotate the drill bit 20. To rotate the drill bit 20, the positioning arc block 25 needs to apply sufficient force to the push block 26. When force is applied, the pushing block 26 can transfer the force received to the drill rod tail through the fixing block 21, thereby adjusting the clamping force of the fixing block 21 on the drill rod tail. When the gear ring 30 just starts to rotate, the elastic force of the spring 39 needs to be overcome so that the clamping force of the fixing block 21 on the drill rod tail reaches the target clamping force. As the gear ring 30 rotates, the elastic force of the spring 39 needs to be overcome increases, and the clamping force of the fixing block 21 on the drill rod tail also increases, ensuring that the minimum clamping force of the fixing block 21 on the drill rod tail is the target clamping force, thus improving the connection stability between the drill bit 20 and the drill rod.

[0050] The working principle of the above technical solution is as follows:

[0051] The extension and retraction of the hydraulic cylinder 2 can drive the support plate 2 to move, and the guide shaft 6 plays a connecting, supporting and guiding role for the support plate 2.
