Description
Technical Field
[0001] The present invention belongs to the technical field of slope protection, and specifically relates to a slope protection drilling device. Background Art
[0002] Slope protection refers to a comprehensive measure that uses engineering and technical means to reinforce, stabilize, and protect natural or artificial slopes to prevent geological disasters such as landslides, collapses, and debris flows, and to ensure the safety of engineering facilities and personnel. Its core goal is to maintain the mechanical balance of the slope and reduce the impact of environmental factors (such as rainfall, earthquakes, and weathering) on slope stability.
[0003] Slope protection drilling refers to the construction process of forming holes in slope rock masses or soil masses through mechanical or manual means in slope protection projects for installing support structures (such as anchor rods and cables), drainage facilities (such as drainage holes), or conducting geological exploration. Its core purpose is to enhance slope stability, control groundwater seepage, or obtain geological parameters, and it is a key technical link in the slope protection system.
[0004] In the current prior art, when drilling shallow holes in high-strength, low-permeability, and low groundwater level soil layers, such as hard plastic clay, dense sand, and gravel soil, a direct drilling method (i.e., without mud or casing wall protection) is usually used. When the existing devices drill slopes of such soil layers, due to the shallow drilling depth, in order to improve the flexibility of device use, a method of splicing short drill pipes is used to drill the slope.
[0005] When the short drill pipes drill the above-mentioned soil layers, since the drill pipes are spliced and rotated, there may be small gaps or misalignments at each connection, resulting in eccentricity of the drill pipes during rotation, which in turn causes vibration. Vibration not only causes the drilling position to shift, reduces the drilling efficiency and increases equipment wear, but may also cause instability of the hole wall and affect subsequent grouting and other operations. Therefore, the present invention provides a slope protection drilling device. Summary of the Invention
[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

The interior of the housing is configured with a vibration damping component for assisting in drilling the slope. A fixed frame is fixedly connected inside the housing. A driving machine is provided behind the housing, and a lift is also provided above the housing.
[0008] The shock absorption assembly includes a drilling rig that slides on the upper surface of a fixed frame. An installation sleeve is installed at the output end of the drilling rig. A connecting sleeve is arranged on the outer surface of the installation sleeve. A moving ring is provided at the front end of the connecting sleeve. Four groups of elastic telescopic rods are arranged on the surface of the moving ring. The left and right two groups of elastic telescopic rods are threadedly connected to the moving ring, and the upper and lower two groups of elastic telescopic rods are slidably connected to the moving ring. Spline connections are made between the left and right two groups of elastic telescopic rods and a gear. One end of the four groups of elastic telescopic rods is rotatably connected to a contact roller. An incomplete rack is meshed and connected below the gear. The upper and lower two groups of elastic telescopic rods are respectively in sliding contact with two triangular plates at one end.
[0009] Preferably, the moving ring is sleeved on the surface of the drill pipe. A limiting rod is provided above the drill pipe, and a groove is opened inside the limiting rod. One triangular plate is fixedly connected to the groove inside the limiting rod. A groove is also opened inside the fixed frame, and the other triangular plate is fixedly connected to the groove inside the fixed frame. The limiting rod is fixedly connected to the housing.
[0010] Preferably, an installation shell is fixedly connected to the front of the fixed frame. A cooperation assembly for assisting workers in replacing the drill pipe is configured inside the installation shell. The cooperation assembly includes a shifting rod and a rotating ring. Multiple arc plates are fixedly connected to the inner surface of the rotating ring. An extrusion rod is in sliding contact with the surface of the arc plate. One end of the extrusion rod is provided with a slider, and the slider is slidably connected to the installation shell. One end of the slider is fixedly connected to a clamping plate.
[0011] Preferably, two spring columns are also arranged on the surface of the slider. The other ends of the spring columns are fixedly connected to the installation shell. A chute is opened inside the installation shell, and the slider slides inside the chute. A return spring is arranged inside the extrusion rod.
[0012] Preferably, the driving machine can drive the drilling rig to slide on the surface of the fixed frame through air pressure or hydraulic pressure. The fixed frame is threadedly connected to a lift, and the lift is fixedly connected to the housing.
[0013] Preferably, four universal wheels are arranged at the bottom of the housing. One end of the limiting rod is fixedly connected to the installation shell. A dust collector is communicated inside the installation shell. The limiting rod is located directly above the fixed frame.
[0014] Preferably, the shifting rod is slidably connected to the installation shell, and the clamping plate is sleeved on the surface of the drill pipe.
[0015] Preferably, two groups of the gear and the incomplete rack are arranged on both sides of the fixed frame. The incomplete rack is fixedly connected to the housing. A bracket is rotatably connected to the side of the gear, and the bracket is slidably connected to the fixed frame. The elastic telescopic rod is slidably connected to the bracket.
[0016] Preferably, damping springs are arranged inside the upper and lower groups of elastic telescopic rods, and one end of the incomplete rack is fixedly connected to the installation shell.
[0017] Preferably, the drilling rig and the fixing frame are arranged obliquely at a certain angle, and the inside of the moving ring is provided with a cavity.
[0018] The beneficial effects of the present invention are as follows:
[0019] 1. For the slope protection drilling device of the present invention, through the intermittent meshing of the gear and the incomplete rack, the left and right groups of elastic telescopic rods can be driven to move towards the position of the drill pipe. At the same time, during the movement of the upper and lower groups of elastic telescopic rods, they will contact the triangular plate, so that the four contact rollers can clamp and damp the drill pipe during drilling, effectively reducing the vibration amplitude and vibration frequency of the drill pipe during drilling, improving the quality of slope drilling by the drill pipe, protecting the drilled holes, and having high practicability.
[0020] 2. For the slope protection drilling device of the present invention, the stopped drill pipe is clamped and limited by multiple groups of clamping plates.

Specific implementation manners
[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.
[0033] As Figures 1 to 6 shown, a slope protection drilling device according to an embodiment of the present invention includes a housing 1 and a drill pipe 4. The interior of the housing 1 is configured with a vibration damping component 100 for assisting in drilling the slope. A fixed frame 5 is fixedly connected inside the housing 1. A driving machine 6 is arranged behind the housing 1. An elevator 3 is also arranged above the housing 1;
[0034] The vibration damping component 100 includes a drilling rig 101. The drilling rig 101 is slidably connected to the upper surface of the fixed frame 5. An installation sleeve 102 is installed at the output end of the drilling rig 101. A connecting sleeve 103 is arranged on the outer surface of the installation sleeve 102. A moving ring 104 is arranged at the front end of the connecting sleeve 103. Four groups of elastic telescopic rods 105 are arranged on the surface of the moving ring 104. The left and right two groups of elastic telescopic rods 105 are threadedly connected to the moving ring 104. The upper and lower two groups of elastic telescopic rods 105 are slidably connected to the moving ring 104. The left and right two groups of elastic telescopic rods 105 are splined with a gear 108. One end of the four groups of elastic telescopic rods 105 is rotatably connected with a contact roller 106. The lower part of the gear 108 is meshed with an incomplete rack 109. One end of the upper and lower two groups of elastic telescopic rods 105 respectively slidably contacts two triangular plates 110.
[0035] First, push this device to the side of the slope and adjust the position where drilling is to be carried out. Then, start the elevator 3 to drive the fixed frame 5 to move up and down. Next, rotate and install the drill rod 4 inside the mounting sleeve 102, enabling the drilling rig 101 to drive it for drilling. At the same time, it is convenient to adjust the height of the drill rod 4 for drilling the slope. During operation, start the drilling rig 101 to drive the drill rod 4 inside the mounting sleeve 102 to rotate. Then, drive the drilling rig 101 to slide on the surface of the fixed frame 5 through an external power source driving machine 6, enabling the drill rod 4 to move while rotating and applying pressure to it, so as to drill the slope. It should be noted that when the drill rod 4 is drilling the slope, since the connecting sleeve 103 is arranged in the middle position between the mounting sleeve 102 and the moving ring 104, at this time, the movement of the drilling rig 101 on the surface of the fixed frame 5 will also drive the moving ring 104 to move. The movement of the moving ring 104 can drive the four groups of elastic telescopic rods 105 to move. When the left and right two groups of elastic telescopic rods 105 move, they can drive the gears 108 spline-connected to their surfaces to move synchronously. During the movement of the gears 108, they will intermittently engage with the lower incomplete rack 109 and thus rotate. Since the elastic telescopic rods 105 on both sides are threadedly connected to the moving ring 104, at this time, the rotation of the elastic telescopic rods 105 can make the contact rollers 106 at one end of them intermittently approach the axis of the drill rod 4 and apply pressure to the surface of the drill rod 4. When the drill rod 4 starts to drill the slope, since the end of the drill rod 4 contacts the soil layer, and the hardness of the soil layer is relatively high, and there is a gap between the surface of the drill rod 4 and the drilled hole on the slope surface, and the contact rollers 106 are elastically in contact with the moving ring 104, the drill rod 4 will vibrate to a certain extent as a whole during the drilling process, and the amplitude of the vibration is relatively large. At this time, multiple contact rollers 106 contact the surface of the drill rod 4, which can reduce the vibration amplitude of the drill rod 4 during drilling, avoid the phenomenon of position deviation at the beginning of drilling, and effectively improve the accuracy of the drilling position;
[0036] It should be further noted that when the drill pipe 4 drills a hole, it will continuously insert into the inside of the slope. At this time, the drill pipe 4 will gradually sink into the inside of the slope. When half of the length of the drill pipe 4 sinks into the inside of the slope, the drill pipe 4 will be limited by the slope and its vibration amplitude will be reduced. However, due to the gap between the surface of the drill pipe 4 and the drilled hole on the slope surface, and the elastic contact between the contact roller 106 and the moving ring 104, although the vibration amplitude will be reduced, the vibration frequency will increase significantly. And because it works by directly drilling, the excessive vibration frequency at this time will damage the inner wall of the drilled hole. At this time, since the contact roller 106 will intermittently squeeze the surface of the drill pipe 4 during the movement, and the gear 108 and the incomplete rack 109 are intermittently engaged. When the drill pipe 4 gradually sinks into the inside of the slope, multiple groups of contact rollers 106 will continuously increase the extrusion force on the drill pipe 4, so that it can be converted from reducing the vibration amplitude of the drill pipe 4 to reducing its vibration frequency, effectively improving the stability of the drill pipe 4 during drilling, improving the quality of drilling, protecting the drilled hole at the same time, and facilitating subsequent operations such as grouting the hole;
[0037] It should be further noted that when the contact rollers 106 on the left and right sides of the moving ring 104 limit and damp the vibration of the drill pipe 4, the elastic telescopic rods 105 located on the upper and lower sides of the moving ring 104 will also move synchronously at this time. At this time, the movement of the elastic telescopic rods 105 will slide into contact with the inclined surface of the triangular plate 110. And because the inclined surface of the triangular plate 110 is inclined higher at the position closer to the slope, the contact of the triangular plate 110 with its inclined surface will also cause the upper and lower two groups of contact rollers 106 to limit and damp the vibration of the drill pipe 4. Since the four groups of contact rollers 106 will move synchronously with the drill pipe 4 to the position of the slope at this time, even if the drill pipe 4 vibrates, it will, under the action of the slope and multiple groups of contact rollers 106, reduce its vibration amplitude and vibration frequency at the same time, effectively damping the drill pipe 4 with good damping effect.
[0038] As Figures 3 to 6 shown, the moving ring 104 is sleeved on the surface of the drill pipe 4. A limiting rod 107 is arranged above the drill pipe 4, and a groove is opened inside the limiting rod 107. A group of triangular plates 110 are fixedly connected in the groove inside the limiting rod 107. A groove is also opened inside the fixing frame 5, and another group of triangular plates 110 are fixedly connected in the groove inside the fixing frame 5. The limiting rod 107 is fixedly connected to the housing 1.
[0039] During operation, the two sets of triangular plates 110 are respectively installed in the grooves formed inside the limit rod 107 and the fixed frame 5. Since the four sets of elastic telescopic rods 105 are all made of elastic materials, when the upper and lower sets of elastic telescopic rods 105 come into contact with the inclined surface of the limit rod 107 and move, the contact rollers 106 at one end of the elastic telescopic rods 105 can slowly press the surface of the drill pipe 4, effectively improving the vibration reduction effect on the drill pipe 4. It should be noted that when the drill pipe 4 just starts to drill into the slope for drilling, the surface of the slope may be some soil layers. At this time, the amplitude and frequency of the vibration of the drill pipe 4 during drilling will be at the minimum value. At this time, the contact rollers 106 at one end of the multiple sets of elastic telescopic rods 105 can carry out vibration reduction work on the drill pipe 4, and the drill pipe 4 will not cause the drill rig 101 or the device itself to vibrate when vibrating, which can protect the device and improve the drilling effect on the slope at the same time;
[0040] It should be further explained that even when starting to drill into the slope for drilling, if the surface hardness of the slope is relatively high, at this time, since the slope does not limit the drill pipe 4, the amplitude of its vibration must be greater than the frequency of vibration. At this time, the four sets of contact rollers 106 do not clamp the drill pipe 4 either, but only play a role in vibration reduction. There is a relatively large movement space between the multiple sets of contact rollers 106 and the moving ring 104. It can not only reduce the amplitude of the drill pipe 4, but also prevent the drill pipe 4 from vibrating too much and damaging the moving ring 104, with high safety, can reduce the overall vibration amplitude of the drill pipe 4 at the beginning of drilling, and improve the stability of the drill pipe 4 during drilling.
[0041] As Figure 1 and Figures 7 to 9 shown, an installation shell 2 is fixedly connected to the front of the fixed frame 5. A cooperation assembly 200 for assisting workers to replace the drill pipe 4 is arranged inside the installation shell 2. The cooperation assembly 200 includes a shift lever 201 and a rotating ring 202. Multiple arc plates 203 are fixedly connected to the inner surface of the rotating ring 202. An extrusion rod 205 is in sliding contact with the surface of the arc plate 203. One end of the extrusion rod 205 is provided with a slider 204. The slider 204 is slidably connected to the installation shell 2. One end of the slider 204 is fixedly connected to a clamping plate 206.
[0042] During operation, when the drill pipe 4 starts to drill the slope, first, the operator presses down the lever 201 to drive the rotating ring 202 to rotate inside the mounting shell 2. Since there are multiple arc plates 203 inside the rotating ring 202, the rotating ring 202 will also drive the arc plates 203 to rotate at this time. And because the contact surface between the arc plate 203 and one end of the extrusion rod 205 is set at a certain height, when the arc plate 203 rotates, it will push the slider 204 at one end of the extrusion rod 205 to slide inside the mounting shell 2. At this time, the sliding of the slider 204 can push the clamping plate 206 to contact the surface of the drill pipe 4. It should be noted that at this time, the lever 201 pressed by the operator will not directly make the highest point of the arc surface of the arc plate 203 contact the end point of the extrusion rod 205, but only make one end of the extrusion rod 205 located at the middle position of the arc plate 203. Therefore, the clamping plate 206 will not completely contact the surface of the drill pipe 4, preventing the clamping plate 206 from affecting the drill pipe 4. At the same time, since the extrusion rod 205 is telescopically arranged, even if the drill pipe 4 vibrates at this time, there will be a sliding space between the extrusion rods 205, enabling the clamping plate 206 to also damp the vibration of the drill pipe 4. Cooperating with multiple contact rollers 106 at the same time to carry out the vibration damping work on the drill pipe 4, the vibration damping effect is good.
[0043] As Figure 7 and Figure 9 shown, there are also two spring columns 208 arranged on the surface of the slider 204. The other ends of the spring columns 208 are fixedly connected to the mounting shell 2. A chute 207 is opened inside the mounting shell 2, and the slider 204 slides inside the chute 207. A return spring is arranged inside the extrusion rod 205.
[0044] During operation, when the drill pipe 4 is drilling, since the arc plate 203 has been adjusted to push the extrusion rod 205 to make the clamping plate 206 tightly attached to the surface of the drill pipe 4, when the drill pipe 4 vibrates, it will continuously push the slider 204 to slide inside the mounting shell 2. At this time, through the multiple spring columns 208 arranged and the return spring inside the extrusion rod 205, the clamping plate 206 can be pushed to always tightly adhere to the surface of the drill pipe 4, and the vibration damping work can be carried out on it, improving the stability of the drill pipe 4 during drilling.
[0045] As Figures 1 to 4 shown, there are two limit plates 111 arranged on both sides of the incomplete rack 109. The width between the two limit plates 111 is the same as the width of the gear 108. The teeth on the surface of the incomplete rack 109 are arranged in multiple segments, and the length of each segment of teeth on the surface of the incomplete rack 109 is equal to half of the circumference of the gear 108. The two sides of the gear 108 are slidably connected to the limit plates 111.
[0046] During operation, when the gear 108 moves, it will first engage with the teeth on the surface of the incomplete rack 109. Since the length of the incomplete rack 109 is equal to half of the circumference of the gear 108, when the gear 108 engages with the first section of teeth on the incomplete rack 109, the gear 108 will rotate 180°. At this time, the gear 108 will drive the elastic telescopic rod 105 to move threadedly into the interior of the moving ring 104. At this time, multiple contact rollers 106 can contact the drill pipe 4. It should be noted that when the gear 108 does not engage with the teeth on the surface of the incomplete rack 109, since the elastic telescopic rod 105 has rotated into the interior of the moving ring 104 at this time, and there are two sets of limit plates 111 arranged on both sides of the gear 108, even if the gear 108 does not engage with the teeth on the surface of the incomplete rack 109 at this time, the two sets of limit plates 111 can prevent the gear 108 from disengaging from the incomplete rack 109, enabling the gear 108 to always be above the incomplete rack 109 and ensuring the stability of the gear 108 during movement. When the drill pipe 4 continuously drills into the slope, when the gear 108 engages with the second section of teeth on the incomplete rack 109, the contact roller 106 will continue to perform extrusion work on the drill pipe 4. Because at this time, the vibration amplitude of the drill pipe 4 will decrease, but the vibration frequency will increase. The movement of the contact roller 106 can further limit and dampen the drill pipe 4 with a reduced vibration amplitude but an increased vibration frequency, effectively improving the vibration damping effect on the drill pipe 4;
[0047] Furthermore, it should be noted that since the elastic telescopic rod 105 is threadedly connected to the moving ring 104, when the elastic telescopic rod 105 is not engaged with the teeth on the surface of the incomplete rack 109 due to the reverse rotation of the gear 108 or is rotated by an external force, at this time, through the cooperation of the threads on the surface of the elastic telescopic rod 105 and the limit plates 111, it can effectively prevent the gear 108 on the surface of the elastic telescopic rod 105 from reversing itself due to vibration when it is not engaged with the teeth on the surface of the incomplete rack 109, enabling the contact roller 106 at one end of the elastic telescopic rod 105 to always contact the drill pipe 4 and perform vibration damping work on the drill pipe 4, with a good vibration damping effect.
[0048] As Figures 7 to 9 shown, the lever 201 is slidably connected to the mounting shell 2. The clamping plates 206 are sleeved on the surface of the drill pipe 4, and multiple clamping plates 206 are arranged at an angle of 120°. Washers are provided at the positions where the clamping plates 206 contact the surface of the drill pipe 4, and the washers are made of wear-resistant materials.
[0049] During operation, when multiple sets of clamping plates 206 come into contact with the surface of the drill pipe 4, when the drill pipe 4 rotates for drilling, the drill pipe 4 will contact the washers provided on the clamping plates 206. The washers can not only ensure full contact between the clamping plates 206 and the drill pipe, improve the vibration damping effect of the clamping plates 206 on the drill pipe 4, but also, when the drill pipe 4 needs to be replaced, the full contact between the washers and the drill pipe 4 can improve the stability of the drill pipe 4 when the drilling rig 101 rotates in the reverse direction to disengage it, facilitating the subsequent installation of the drill pipe 4 and effectively improving the replacement efficiency of the drill pipe 4.
[0050] As Figures 1 to 4 shown, one end of the limit rod 107 is fixedly connected to the mounting shell 2, and the limit rod 107 is located directly above the fixed frame 5. The cross-section of the triangular plate 110 at the end closer to the slope is larger than that at the end farther from the slope.
[0051] During operation, since one side of the triangular plate 110 is inclined at a certain angle, when one end of the upper and lower sets of elastic telescopic rods 105 comes into contact with the inclined surface of the triangular plate 110, the elastic telescopic rods 105 will be subjected to the extrusion force of the triangular plate 110. At this time, the elastic telescopic rods 110 will drive the upper and lower sets of contact rollers 106 and the left and right sets of contact rollers 106 to simultaneously squeeze the drill pipe 4. Since the left and right contact rollers 106 move when intermittently meshing with the multiple teeth on the surface of the gear 108 and the incomplete rack 109, but the contact between the triangular plate 110 and the upper and lower sets of elastic telescopic rods 105 will continuously push the contact rollers 106 to squeeze the drill pipe 4. Therefore, the extrusion forces of the upper and lower sets of contact rollers 106 and the left and right sets of contact rollers 106 on the drill pipe 4 are different, thus avoiding the four sets of contact rollers 106 simultaneously squeezing the drill pipe 4 and affecting the drilling operation of the drill pipe 4, and improving the stability of the drill pipe 4;
[0052] During operation, when the drill pipe 4 needs to be connected and continue drilling, at this time, the operator presses the lever 201 downward. The movement of the lever 201 can drive the arc plate 203 inside the rotating ring 202 to continuously squeeze the extrusion rod 205. When the sliding space inside the extrusion rod 205 is compressed to the extreme, the extrusion rod 205 will push the clamping plate 206 below the slider 204 to completely clamp the drill pipe 4. It should be noted that at this time, the drilling rig 101 is in a non-operating state. After multiple sets of clamping plates 206 complete the clamping of the drill pipe 4, the drilling rig 101 will then reverse to disengage the drill pipe 4 from the mounting sleeve 102, facilitating the operator to install the next section of the drill pipe 4.
[0053] As Figures 1 to 2As shown, the driving machine 6 can drive the drill rig 101 to slide on the surface of the fixing frame 5 through air pressure or hydraulic pressure. The fixing frame 5 is threadedly connected to the lift 3, and the lift 3 is fixedly connected to the housing 1. Four sets of universal wheels are provided at the bottom of the housing 1, and a dust collector is connected to the inside of the mounting shell 2.
[0054] During operation, when most of the drill pipe 4 is immersed in the slope, it is necessary to reverse the drill rig 101 to drive the mounting sleeve 102 to rotate, so that the mounting sleeve 102 is disengaged from one end of the drill pipe 4. After the two are disengaged, the driving machine 6 is started to drive the drill rig 101 to slide above the fixing frame 5, and then one end of a section of the drill pipe 4 is installed to the one end of the drill pipe 4 that has been drilled into the slope. Then, the driving machine 6 is used to control the alignment of the mounting sleeve 102 with the installed one end of the drill pipe 4. At this time, the drill rig 101 is started to drive the mounting sleeve 102 to rotate to install the drill pipe 4 into the inside of the mounting sleeve 102, which is convenient for continuing the drilling work on the slope and can improve the work efficiency.
[0055] During operation, after the device is pushed to the designated location, since the drilling depth is relatively shallow, a large drilling machine cannot meet the drilling use requirements, resulting in waste of demand. At this time, after the device is pushed to the designated location by the staff, the device can be simply fixed through the four sets of universal wheels, and then the overall fixation of the device is carried out, which can further improve the stability of the drill pipe 4 during drilling. The dust generated by the drill pipe 4 during the drilling process can also be cleaned by the dust collector, which will not affect the external environment and can improve the practicality of the device use and is convenient for handling.
[0056] As Figures 1 to 4 shown, two sets of gears 108 and incomplete racks 109 are provided on both sides of the fixing frame 5. The incomplete rack 109 is fixedly connected to the housing 1. A bracket is rotatably connected to the side of the gear 108, and the bracket is slidably connected to the fixing frame 5. The elastic telescopic rod 105 is slidably connected to the bracket.
[0057] During operation, when the drill rig 101 rotates to drive the drill pipe 4 to drill the slope, the incomplete rack 109 is fixed at this time, and the gear 108 will mesh with the incomplete rack 109 while moving. At the same time, brackets are provided on both sides of the gear 108, which can prevent the gear 108 from moving synchronously when the elastic telescopic rod 105 moves into the moving ring 104, so that the gear 108 and the incomplete rack 109 are disengaged, and the effect of the contact roller 106 at one end of the elastic telescopic rod 105 on limiting and damping the drill pipe 4 can be effectively improved.
[0058] After the contact rollers 106 at one end of multiple groups of elastic telescopic rods 105 come into contact with the surface of the drill pipe 4, the vibration generated by the drill pipe 4 during the drilling process will be reduced by the damping springs provided inside the elastic telescopic rods 105. At the same time, since the contact rollers 106 will continuously increase the extrusion force on the drill pipe 4 during the drilling process of the drill pipe 4, the vibration frequency of the drill pipe 4 can be reduced after it slowly drills into the slope, which can protect the inner wall of the drilled hole and the drilling quality is high.
[0059] As Figures 2 to 4 shown, the drilling rig 101 and the fixing frame 5 are arranged at a certain angle. The inside of the moving ring 104 is provided with a cavity. Damping springs are provided inside the upper and lower groups of elastic telescopic rods 105. One end of the incomplete rack 109 is fixedly connected to the mounting shell 2.
[0060] During operation, by arranging the drilling rig 101 and the fixing frame 5 at a certain angle, it can meet the drilling requirements for slopes with different inclination angles, effectively improve the quality of slope drilling. At the same time, by setting the inside of the moving ring 104 to a cavity state, it is not only convenient for the upper and lower groups of contact rollers 106 to move to clamp and damp the surface of the drill pipe 4, but also convenient for the left and right groups of contact rollers 106 to clamp and damp the surface of the drill pipe 4 while leaving enough rotation space to achieve a state where all four groups of contact rollers 106 are in contact with the surface of the drill pipe 4, and can fully reduce the vibration amplitude or vibration frequency of the drill pipe 4 at multiple angles.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
