Description

Technical Field

[0001] The present invention relates to the technical field of slope protection, and in particular to a slope protection anchoring device. Background Art

[0002] Grouting anchor rods are new products developed based on the actual needs of my country's tunnel projects, slope control projects, coal mine tunnel projects, etc. The main products are: ordinary hollow grouting anchor rods; self-propelled hollow grouting anchor rods; shell-expanding hollow grouting anchor rods; combined hollow grouting anchor rods. The anchor rod body of the grouting anchor rod adopts a hollow design, and the hole in the rod body is used as a drilling high-pressure wind and water channel and a grouting channel. Compared with a solid rod body, the hollow rod body design can obtain better rigidity and shear strength. The outer surface of the anchor rod has a standard large-pitch thread structure along the entire length. The thread structure facilitates the cutting and extension of the anchor rod. Compared with a smooth rod body, it increases the bonding area between the anchor rod body and the grouting material, thereby improving the anchoring force. When using self-propelled hollow grouting anchor rods to protect slopes, there is no need to pre-drill holes for anchor rod fixing on the slopes. During the installation of the anchor rods, the drill bit and self-rotation on the anchor rods are used to achieve the installation of the anchor rods. However, due to the complex structure of the slopes and inconsistent rock properties of the slopes, the thrust between the anchor rods and the slopes during drilling is inconsistent. When the thrust is too small, the drilling efficiency of the anchor rods is low and idling is likely to occur. When the thrust is too large, the anchor rods are easily stuck by the slopes. Therefore, it is necessary to adjust the thrust of the anchor rods. At the same time, the thrust stroke of the existing anchoring device is limited. For this purpose, a slope protection anchoring device is proposed. Summary of the Invention

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example 1 Please combine Figures 1-9 The slope protection anchoring device of this embodiment includes an anchor rod 4 and a protective net arranged on the anchor rod 4. The anchor rod 4 includes a rod body 41, a drill bit 42 arranged at the front end of the rod body 41, and a plug tube 47 arranged at the rear end of the rod body 41. A grout stopper 43, a support plate 44, a locking plate 45 and a nut 46 are sequentially arranged on the outside of the rod body 41. A positioning hole 48 is passed through the support plate 44. The locking plate 45 is fixedly connected to a push rod 49 that is connected to the positioning hole 48. Fix the anchor rod 4 on the slope, then pass the protective net through the rod body 41, and place the protective net between the support plate 44 and the locking plate 45. Insert the top rod 49 on the locking plate 45 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 offset deformation of the protective net during the pulling process, thereby improving the overall stability and strength of the anchoring device. The drilling system further includes a main body 1 provided with an opening, a pushing assembly 2 provided on the main body 1 for pushing the anchor rod 4 forward, a drilling detection assembly 3 provided on the top of the pushing assembly 2 for driving the anchor rod 4 to rotate and detecting the pressure of the anchor rod 4, an auxiliary assembly 5 for assisting in pressurizing the anchor rod 4 provided on the bottom of the pushing assembly 2, a stabilizing assembly 7 for maintaining the stability of the anchor rod 4 provided on one side of the front end of the main body 1, and a connecting mechanism 6 installed on the bottom of the main body 1; When anchoring and reinforcing the slope, an anchor rod 4 of corresponding length and model is selected according to the slope reinforcement design requirements, and the anchor rod 4 is installed on the drilling detection component 3. When drilling and installing the anchor rod 4 on the slope, the pushing component 2 is combined with the auxiliary component 5 to push the anchor rod 4 to rotate and advance under the set pressure. At the same time, the thrust of the anchor rod 4 is adjusted according to the pressure between the anchor rod 4 and the slope rock detected by the drilling detection component 3, ensuring that the pressure between the anchor rod 4 and the rock is kept within the set range during rotation drilling, which can avoid the anchor rod 4 from being difficult to drill when idling or the anchor rod 4 from being stuck due to excessive pressure. The pushing assembly 2 includes a driving portion 21 provided in an annular structure inside the main body 1. The driving portion 21 is connected to the front wheel 24 and the rear wheel 27 on the inner side. 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. One end of the rotating shaft 23 extending 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 fixed to the main body 1. The side plate 22 is rotatably connected between the two sets of rotating shafts 23. The auxiliary assembly 5 includes a second driving portion 51 provided in an annular structure at the bottom of the first driving portion 21. Auxiliary wheels 53 are drivingly connected to both ends of the inner ring of the second driving portion 51. The auxiliary wheels 53 are fixedly sleeved with a second rotating shaft 52 that is rotatably sleeved with the main body 1. The outer ring of the second rotating shaft 52 located between the front wheel 24 and the rear wheel 27 is fixedly sleeved with a connecting wheel 54 that is drivingly connected to the outer ring of the first driving portion 21. A coupling mechanism 56 for controllably connecting to the second driving portion 51 is provided between the two sets of auxiliary wheels 53. One end of the coupling mechanism 56 is fixedly connected to a second connecting seat 57 that is slidably connected to the main body 1. A pushing unit 58 fixedly connected to the main body 1 is installed on one side of the second connecting seat 57 that extends out of one end of the main body 1. The lap joint mechanism 56 includes a moving frame 81 slidably connected to the inside of the main body 1 and a partition 82 fixed to the inner side wall of the moving frame 81. A turntable 83 is rotatably sleeved on one side of the partition 82. The turntable 83 is fixed with two groups of push rods 85 symmetrically arranged along its axis. The partition 82 is penetrated by two groups of guide channels 86 distributed along the axis of the turntable 83, and the push rods 85 are slidably connected to adjacent guide channels 86. Two groups of pressing plates 87 are slidably connected to the other side of the partition 82, and the pressing plates 87 slide along the height direction of the moving frame 81. A docking groove 88 is provided along the length direction of the pressing plate 87 at one end of the pressing plate 87 close to the partition 82. The push rod 85 extends from the guide channel 86 and is slidably connected to the adjacent docking groove 88. A clamping plate 89 for clamping with the driving part 2 51 is installed on the side close to each other of the two groups of pressing plates 87. The turntable 83 is fixedly sleeved with a rotating shaft 3 84, and a motor 1 fixedly connected to the moving frame 81 is installed at the end of the rotating shaft 3 84. Both sets of clamping plates 89 are provided with clamping teeth that clamp with the driving part 2 51; the driving part 1 21 and the driving part 2 51 adopt either a chain or a toothed belt, and the front wheel 24 and the rear wheel 27 and the connecting wheel 54 have the same structure and are engaged with the driving part 1 21; when the motor 1 is started, the turntable 83 rotates, and then the two sets of push rods 85 move, and the two sets of push rods 85 drive the two sets of pressing plates 87 to move toward each other, so that the clamping plate 89 moves, and the clamping plate 89 clamps with the driving part 2 51; When the second drive part 51 adopts a chain, the teeth on the clamping plate 89 extend into the interior of the chain to clamp it. When the second drive part 51 adopts a toothed belt, the clamping plate 89 is clamped with the toothed belt. Then, the pushing unit 58 is started to drive the second drive part 51 to rotate, so that the connecting wheel 54 can drive the first drive part 21 to rotate, realizing the auxiliary pressurization operation of the first drive part 21. 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 sets 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 starts, 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, thereby使 the first driving part 21 to move. When the second driving part 51 moves, it带动 the drilling detection component 3 thereon 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 drill bit 42 at the front end 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 with the anchor rod 4 during the rotating drilling process. Then, the first pushing unit 26 starts,使 the pushing component 2 as a whole to move 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 pressurization and propulsion for 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-structured 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 drilled hole. After the drilling is completed, the grouting slurry is输送 into the drilled hole to reinforce the anchor rod 4; 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; 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 severe cases, the anchor rod 4 rotates idly. Therefore, it is necessary to use the auxiliary component 5 for auxiliary pressurization. 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 first driving part 21 for pressurization operation during the drilling of the anchor rod 4; 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 getting stuck, and the thrust of the anchor rod 4 forward needs to be reduced. 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, and the driving part 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 driving part 21, reduce the drilling pressure of the anchor rod 4, and avoid the anchor rod 4 getting stuck.

The slide groove 37 is slidably sleeved with a movable disk 38 slidably connected to the protective cover shell 34, and the movable disk 38 moves along the length direction of the protective cover shell 34.

The end of the barrel 32 is mounted with a water pipe 312 and a feed pipe 313. The cross-section of the inner ring of the docking tube 35 is a regular polygon. The cross-section of the outer ring of the end of the anchor rod mounting tube 36 extending into the docking tube 35 is consistent with the cross-section of the inner ring of the docking tube 35. The second motor starts to drive the gear and the gear ring to rotate, so that the docking tube 35 rotates, and then drives the anchor rod mounting tube 36 to rotate, thereby driving the anchor rod 4 fixed on the anchor rod mounting tube 36 to rotate. When the anchor rod 4 rotates, the drill bit 42 at its front end can drill into the slope.
