Description

Technical Field

[0001] This invention relates to the field of slope protection technology, and in particular to a slope protection anchoring device. Background Technology

[0002] Grouting anchors are new products developed to meet the practical needs of tunnel engineering, slope stabilization engineering, and coal mine roadway engineering in my country. Main products include: ordinary hollow grouting anchors; self-drilling hollow grouting anchors; expansion-shell hollow grouting anchors; and combined hollow grouting anchors. The anchor body of the grouting anchor features a hollow design, with the central hole serving as a high-pressure ventilation and water channel for drilling and a grouting channel. Compared to solid anchor bodies, the hollow design provides better rigidity and shear strength. The outer surface of the anchor body features a full-length standard large-pitch thread structure. This thread structure facilitates the cutting and extension of the anchor, increasing the bonding area between the anchor body and the grouting material compared to a smooth anchor body, thereby improving the anchoring force.

[0003] When using self-drilling hollow grouting anchors for slope protection, it is not necessary to pre-drill holes for anchor fixing on the slope. During the installation process, the anchor is installed by utilizing the drill bit on the anchor and its rotation. However, due to the complex slope structure and inconsistent rock properties, the thrust between the anchor and the slope is inconsistent during drilling. When the thrust is too small, the anchor drilling efficiency is low and it is easy to spin freely. When the thrust is too large, the anchor is easy to get stuck by the slope. Therefore, it is necessary to adjust the anchor pushing force. At the same time, the existing anchoring device has a limited pushing stroke. Therefore, a slope protection anchoring device is proposed. Summary of the Invention

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1

[0035] Please combine Figures 1-9 The slope protection anchoring device of this embodiment includes an anchor rod 4 and a protective net set on the anchor rod 4. The anchor rod 4 includes a rod body 41, a drill bit 42 set at the front end of the rod body 41 and a plug pipe 47 set at the rear end of the rod body 41. A grout stop plug 43, a support plate 44, a locking plate 45 and a nut 46 are arranged sequentially on the outside of the rod body 41. The support plate 44 has a positioning hole 48 through it. The locking plate 45 is fixedly connected to a top rod 49 that is connected to the positioning hole 48.

[0036] Anchor rod 4 is fixed on the slope, and then the protective net is passed through the rod body 41 and placed between the support plate 44 and the locking plate 45. The top rod 49 on the locking plate 45 is inserted into the positioning hole 48. On the one hand, the protective net is clamped and installed, and on the other hand, the top rod 49 restricts the protective net, reducing the degree of displacement and deformation of the protective net during the pulling process; thus improving the overall stability and strength of the anchoring device.

[0037] It also includes a drilling system for drilling the anchor bolt 4. The drilling system includes a main body 1 with an opening. The main body 1 is provided with a pushing component 2 for pushing the anchor bolt 4 forward. The top of the pushing component 2 is provided with a drilling detection component 3 for driving the anchor bolt 4 to rotate and detecting the pressure of the anchor bolt 4. The bottom of the pushing component 2 is provided with an auxiliary component 5 for assisting in pressurizing the anchor bolt 4. A stabilizing component 7 for keeping the anchor bolt 4 stable is provided on one side of the front end of the main body 1. A connecting mechanism 6 is installed at the bottom of the main body 1.

[0038] When anchoring and reinforcing the slope, select anchor rods 4 of the corresponding length and model according to the slope reinforcement design requirements, and install anchor rods 4 on drilling detection component 3. When drilling and installing anchor rods 4 on the slope, use push component 2 in combination with auxiliary component 5 to push anchor rods 4 to rotate and advance under the set pressure. At the same time, adjust the thrust of anchor rods 4 according to the pressure between the anchor rods 4 and the slope rock detected by drilling detection component 3 to ensure that the pressure between the anchor rods 4 and the rock is kept within the set range when the anchor rods 4 are rotating and drilling. This can avoid situations where anchor rods 4 are difficult to drill when they are spinning freely or where anchor rods 4 get stuck due to excessive pressure.

[0039] The pushing component 2 includes a drive part 21 with an annular structure inside the main body 1. The inner side of the drive part 21 is connected to a front wheel 24 and a rear wheel 27. The inner rings of the front wheel 24 and the rear wheel 27 are fixedly sleeved with a rotating shaft 23 that is slidably connected to the main body 1. The end of the rotating shaft 23 that extends out of the main body 1 is rotatably sleeved with a connecting seat 25. The connecting seat 25 is connected to a pushing unit 26 that is fixed to the main body 1. A side plate 22 is rotatably connected between the two sets of rotating shafts 23.

[0040] The auxiliary component 5 includes a second drive unit 51 with an annular structure at the bottom of the first drive unit 21. Both ends of the inner ring of the second drive unit 51 are connected to auxiliary wheels 53. The auxiliary wheels 53 are fixedly sleeved with a second shaft 52 that is rotatably sleeved with the main body 1. The outer ring of the second shaft 52 located between the front wheel 24 and the rear wheel 27 is fixedly sleeved with a connecting wheel 54 that is rotatably connected with the outer ring of the first drive unit 21. A connecting mechanism 56 for controllable connection with the second drive unit 51 is provided between the two sets of auxiliary wheels 53. One end of the connecting mechanism 56 is fixedly connected to a second connecting seat 57 that is slidably connected with the main body 1. A second push unit 58 that is fixedly connected to the main body 1 is installed on the side of the second connecting seat 57 that extends out of the main body 1.

[0041] The overlapping mechanism 56 includes a movable frame 81 slidably connected inside the main body 1 and a partition 82 fixed to the inner side wall of the movable frame 81. A turntable 83 is rotatably sleeved on one side of the partition 82. Two sets of push rods 85 are fixedly connected to the turntable 83 and arranged symmetrically along its axis. Two sets of guide channels 86 distributed along the axis of the turntable 83 pass through the partition 82, and the push rods 85 are slidably connected to the adjacent guide channels 86. Two sets of pressing plates 87 are slidably connected on the other side of the partition 82, and the pressing plates 87 slide along the height direction of the movable frame 81. A mating groove 88 is opened at the end of the pressing plate 87 near the partition 82 and is arranged along the length direction of the pressing plate 87. After the push rods 85 extend from the guide channels 86, they are slidably connected to the adjacent mating grooves 88. A snap-fit ​​plate 89 for snapping with the drive unit 2 51 is installed on the side of the two sets of pressing plates 87 that are close to each other.

[0042] Turntable 83 is fixedly sleeved with rotating shaft 84. At the end of rotating shaft 84, motor 1 is fixedly connected to moving frame 81. Both sets of locking plates 89 are provided with locking teeth that engage with drive unit 21. Drive unit 1 21 and drive unit 2 51 are either chains or toothed belts. The front wheel 24 has the same structure as the rear wheel 27 and connecting wheel 54 and meshes with drive unit 1 21. When motor 1 starts, turntable 83 rotates, and then two sets of push rods 85 move. The two sets of push rods 85 drive two sets of pressing plates 87 to move towards each other, causing locking plates 89 to move. Locking plates 89 engage with drive unit 2 51.

[0043] When the second drive unit 51 uses a chain, the teeth on the locking plate 89 engage with the chain. When the second drive unit 51 uses a toothed belt, the locking plate 89 engages with the toothed belt. After that, the second push unit 58 starts and drives the second drive unit 51 to rotate, so that the connecting wheel 54 can drive the first drive unit 21 to rotate, thereby realizing the auxiliary pressurization operation of the first drive unit 21.

[0044] When the anchor rod 4 starts to rotate and drill into the slope, the clamping plate 89 on the lapping mechanism 56 of the auxiliary component 5 is clamped with the second driving part 51. The second driving part 51 is clamped and limited by two groups of clamping plates 89, and then the second driving part 51 is in a locked state. Then, the auxiliary wheel 53, the second rotating shaft 52 and the connecting wheel 54 that are传动连接 with the second driving part 51 are all in a locked state. After that, the connecting wheel 54 limits the first driving part 21 to lock the first driving part 21. Then, when the second pushing unit 58 is started, the second pushing unit 58 pushes the second connecting seat 57 to move, so that the lapping mechanism 56 moves, thereby带动 the second driving part 51 to move. When the second driving part 51 moves, it带动 the auxiliary wheel 53, the second rotating shaft 52 and the connecting wheel 54 to rotate, so that the first driving part 21 moves. When the second driving part 51 moves, it带动 the drilling detection component 3 on it to move towards the slope direction. The drilling detection component 3 drives the rotating anchor rod 4 to start rotating drilling operation on the slope. When the front drill bit 42 of the anchor rod 4 drills into the slope, the lapping mechanism 56 does not clamp the second driving part 51. According to the above principle, at this time, the first driving part 21 is in an active state, and at the same time, the first driving part 21 can move along with the anchor rod 4 during the rotating drilling process. Then, the first pushing unit 26 is started, so that the whole pushing component 2 moves towards the slope direction, and then带动 the anchor rod 4 to move forward. At this time, the first driving part 21 is in an active state, and the first driving part 21 can automatically adjust the rotation mode of the first driving part 21 according to the advancing degree of the anchor rod 4. At the same time, according to the pressure detected by the drilling detection component 3, it judges the drilling state of the anchor rod 4 to determine whether it is necessary to use the auxiliary component 5 for auxiliary pressure boosting to carry out the drilling operation. When the anchor rod 4 drills, the cleaning and cooling water enters the料筒 32 along the water pipe 312, and then is输送 along the对接管 35 and the anchor rod installation pipe 36 into the hollow structure of the anchor rod 4, and then is injected into the drilled hole along the drain hole reserved on the anchor rod 4 to clean and cool the anchor rod 4 and the对接钻孔. After the drilling is completed, the grouting slurry is输送 into the drilled hole to carry out the reinforcement operation on the anchor rod 4;

[0045] According to the slope property and the model of the anchor rod 4, set the working pressure P1 of the pressure sensor 310, and the actual pressure P of the pressure sensor 310;

[0046] When P < P1, it means that the drilling pressure between the anchor rod 4 and the slope is too small. At this time, the drilling efficiency of the anchor rod 4 is low, which is not conducive to the drilling operation of the anchor rod 4. In serious cases, the anchor rod 4 rotates idly. Therefore, it is necessary to use the auxiliary component 5 for auxiliary pressure boosting. According to the above method, the auxiliary component 5 is used to clamp the second driving part 51 and推动 the second driving part 51 to rotate to limit and辅助推动 the movement of the first driving part 21, and carry out the pressure boosting operation on the drilling of the anchor rod 4;

[0047] It should be noted that there may be some inaccuracies in the translation due to the lack of clear understanding of some technical terms in the original text. It is recommended to check and correct it in combination with the actual technical content.After pressurization, when P>P1, it indicates that the pressure between the anchor rod 4 and the slope is greater than the actual working pressure. At this time, the anchor rod 4 is prone to jamming. It is necessary to reduce the thrust of the anchor rod 4 forward. At this time, it is only necessary to loosen the overlapping mechanism 56 on the auxiliary component 5. The auxiliary component 5 does not assist in pushing the anchor rod 4. The drive unit 21 is in an unrestricted state. The anchor rod 4 can automatically release the pressure between the slope and the anchor rod 4 according to the free rotation of the drive unit 21, reduce the drilling pressure of the anchor rod 4, and avoid the anchor rod 4 jamming.

[0048] Example 2

[0049] This embodiment, based on embodiment 1, further improves upon the following: the drilling detection component 3 includes a support plate 31 disposed on the top of the main body 1, and the support plate 31 is slidably connected to the top of the main body 1. A connecting plate connected to the drive unit 21 is fixedly connected to the bottom of the main body 1.

The box 33 is rotatably sleeved, and the end of the connecting pipe 35 that extends into the bearing plate 31 abuts against the end of the material cylinder 32. The outer ring of the connecting pipe 35 is equipped with a power mechanism 311 located in the drive box 33. The outer ring of the anchor rod mounting pipe 36 is provided with a sliding groove 37 located inside the protective cover 34. The sliding groove 37 is slidably sleeved with a movable disc 38 that is slidably connected to the protective cover 34. The movable disc 38 moves along the length of the protective cover 34. A baffle 39 that is fixedly sleeved with the protective cover 34 is provided on the side of the movable disc 38 near the drive box 33. Springs are provided on both sides of the movable disc 38. A pressure sensor 310 is provided on the baffle 39.

[0050] Insert the insertion tube 47 on the anchor bolt 4 into the inner ring of the anchor bolt mounting tube 36, and make sure that the cross-section of the inner ring of the anchor bolt mounting tube 36 is consistent with the cross-section of the outer ring of the insertion tube 47, and then connect and fix it using the locking bolts provided on the anchor bolt mounting tube 36.

[0051] One of the springs is fixed to the inner wall of the end of the protective cover 34, and the other spring is fixed to the baffle 39;

[0052] The power mechanism 311 includes a gear ring fixedly sleeved on the outer ring of the connecting pipe 35. A gear meshes on one side of the gear ring.

A water pipe 312 and a feed pipe 313 are installed at the end of the material cylinder 32. The cross-section of the inner ring of the connecting pipe 35 is a regular polygon structure. The cross-section of the outer ring of the anchor bolt installation pipe 36 that extends into the connecting pipe 35 is consistent with the cross-section structure of the inner ring of the connecting pipe 35.

[0053] When the second motor starts, it drives the gear and gear ring to rotate, causing the connecting pipe 35 to rotate, which in turn drives the anchor bolt installation pipe 36 to rotate, thereby causing the anchor bolt 4 fixed on the anchor bolt installation pipe 36 to rotate. When the anchor bolt 4 rotates, the drill bit 42 at its front end can perform drilling operations on the slope.
