Abstract

This invention relates to the field of slope anchoring technology, and particularly to a rock bolt drilling rig for roadway slope support based on water-rich characteristics. The rock bolt drilling rig includes a track assembly and two sets of balancing mechanisms. Each balancing mechanism includes a sliding plate, a sliding groove seat, a translational power assembly, and two sets of two-stage pressure-bearing components. The sliding plate is movably installed inside the sliding groove seat. The two-stage pressure-bearing components include a main pressure-bearing component and a secondary pressure-bearing component. Both the main and secondary pressure-bearing components include a horizontal plate and two side plates. The horizontal and side plates within the secondary pressure-bearing components include a water storage tank seat and two sets of water-storage spiral casings. This invention, without changing the drilling rig position, considers the narrow road surface at the bottom of the slope and the high water content of the soil at the bottom of water-rich soil slopes. It flexibly adjusts the contact position between the two-stage pressure-bearing components and the ground, preventing the soil depression in the contact area from deepening due to water concentration and the superposition of loads, thus ensuring the stability of the drilling rig during operation.

Description

Technical Field

[0001] This invention relates to the field of slope anchoring technology, and particularly to an anchor drilling rig for roadway slope support based on water-rich characteristics. Background Technology

[0002] Tunnel slopes are mainly composed of soil and surrounding rock. Water-rich tunnel slopes with high water content have low shear strength and are prone to slope instability, requiring slope anchoring. Soil consists of three phases: soil particles, water, and air. The ultimate strength of soil against shear slip under external forces is called shear strength. Soil shear strength is composed of the internal friction and cohesion between particles. Cohesion is caused by the molecular attraction of cement and bound water film in the soil. Cohesion includes true cohesion and apparent cohesion. Apparent cohesion refers to the unstable cohesion formed by adsorption or interlocking between sand particles. True cohesion is relatively stable but has a small value, generally between 5-10 kPa, while apparent cohesion is much larger, reaching 20-80 kPa. Apparent cohesion is greatly affected by water content, which greatly affects the soil shear strength. The cohesion of dry loess can reach 250-300 kPa.

[0003] In related technologies, anchor drilling rigs are generally used to anchor roadway slopes. Anchoring roadway slopes can reduce the probability of landslides. For water-rich roadway slopes and the characteristics of their bottom surfaces, due to the high water content in the soil, tracked anchor drilling rigs are more suitable. During roadway slope anchoring operations, the anchor drilling rig moves to the corresponding anchoring location and maintains stability through its own weight and the gripping effect of the tracks. Some anchor drilling rigs are equipped with hydraulic outriggers that support the ground. These outriggers, distributed around the rig body, further maintain the balance between the rig and the ground. Due to limitations in the width of the roadway slope bottom and soil conditions, the hydraulic outriggers of anchor drilling rigs often cannot extend outwards. When the hydraulic outriggers of anchor drilling rigs in related technologies transfer concentrated loads to the bottom surface, the apparent cohesion and shear strength of the soil at the bottom surface are affected due to the high water content of the water-rich soil. The strength of these technologies is generally low. When the ground is subjected to concentrated loads transmitted by hydraulic outriggers, the contact area between the bottom of the hydraulic outriggers and the ground is small, resulting in a large concentrated load on the ground. Furthermore, when water-rich soil is compressed, water in the soil near the outriggers is compressed and seeps out between soil particles. The seeping water is distributed at the hydraulic outriggers, which further increases the local water content of the soil and further reduces the shear strength of the soil near the outriggers. The road surface under the load of the hydraulic outriggers is prone to subsidence and local overturning. The outriggers can only be reopened by moving the tracked drilling rig, which is cumbersome. Moreover, after the tracked drilling rig is moved, in order to keep the position of the upper anchor drill unchanged and ensure the accuracy of the anchor drill, higher requirements are placed on the coverage, flexibility, and operational difficulty of the adjusting arm above the drilling rig. Therefore, this invention proposes an anchor drill rig for roadway slope support based on water-rich characteristics, aiming to solve the above-mentioned technical problems to a certain extent. Summary of the Invention

[0004] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0005] Tracked anchor drilling rigs are widely used in slope anchoring operations due to their high mobility and stability. However, when working on water-rich soil slopes, the high water content at the slope bottom and the low shear strength and cohesion of the soil cause settlement at the contact points, even with a large contact area between the tracks and the ground. This affects the balance of the entire anchor drilling rig and negatively impacts the accuracy of the drill rod mechanism on the upper side of the rig. Before the work in a certain area is completed, the anchor drilling rig should not be moved, and the contact position between the track and the ground should not be changed. Otherwise, it will interfere with the accuracy of the slope anchor drilling and affect the efficiency of the work. Some drilling rigs are equipped with hydraulic outriggers to help improve the stability of the contact between the drilling rig and the ground. However, the contact area between the hydraulic outriggers and the ground is small, and the concentrated load on the ground is large. The road surface under the load of the hydraulic outriggers is prone to depression and local overturning. In addition, the road surface at the bottom of the slope is generally narrow, so it is not advisable to install deployable hydraulic outriggers to change the contact position between the hydraulic outriggers and the ground.

[0006] The present invention aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, embodiments of the present invention propose an anchor drilling rig for roadway slope support based on water-rich characteristics. During operation, the rig can adjust the contact position between the additional structure and the ground without changing the rig position or affecting the operation of the drill rod mechanism. It also prevents the ground in the contact area from continuously developing into a depression due to the combined effect of water concentration and load, thus providing support and protection for the stability of the rig during operation.

[0008] According to an embodiment of the present invention, a rock bolt drilling rig for roadway slope support based on water-rich characteristics includes a track assembly and two sets of balancing mechanisms. The two sets of balancing mechanisms are symmetrically arranged on both sides of the track assembly. Each set of balancing mechanisms includes a sliding plate, a sliding seat, a translational force assembly, and two sets of two-stage pressure-bearing components. The sliding plate is movably installed inside the sliding seat, and the sliding direction of the sliding plate is consistent with the moving direction of the track assembly. The translational force assembly is installed at the bottom of the sliding seat and is drivenly connected to the sliding plate. The pressure-bearing components are arranged at intervals along the length of the slide plate. Each set of two pressure-bearing components is vertically movably connected to the slide plate and includes a main pressure-bearing component and a sub-pressure-bearing component that are rotatably connected. The main pressure-bearing component and the sub-pressure-bearing component each include a horizontal plate and at least two side plates disposed on the bottom surface of the horizontal plate. Each horizontal plate and each side plate in the sub-pressure-bearing component includes a water storage tank seat and two sets of water storage volutes that are interconnected. The water storage tank seat is arranged in a T-shape vertically and includes an upper support section and a lower support section.

[0009] According to an embodiment of the present invention, a roadway slope support anchor drilling rig based on water-rich characteristics uses two sets of balancing mechanisms as the stabilizing structure of the anchor drilling rig, excluding the track assembly, thereby improving the gripping stability of the drilling rig during operation. The main bearing component and the secondary bearing component can increase the contact area with the ground after unfolding. When the water-rich soil slope bottom pavement is compressed, water in the soil is exuded and enters the water storage tank along the water storage volute, thereby separating from the soil particles and preventing excessive water local concentration that could cause local overturning of the compressed soil. The water storage tank includes a strip-shaped lower support section that can store a considerable amount of water. When the secondary bearing component rotates around the main bearing component and retracts, the water in the water storage tank can be discharged from the permeable holes provided on the side of the secondary bearing component. The two-stage bearing components can extend and retract vertically, and without changing the position of the anchor drilling rig, under the drive of the translational force component, the sliding plate can drive the two-stage bearing components to translate along the length of the sliding seat to change the contact position between the two-stage bearing components and the ground.

[0010] In some embodiments, the anchor drilling rig further includes a workbench with a positioning plate mounted on it. The track assembly is provided in two sets, which are symmetrically distributed about the centroid of the positioning plate. The sliding plate and the sliding groove seat correspond one-to-one, and the two sliding groove seats are respectively installed at both ends of the positioning plate.

[0011] In some embodiments, when the main pressure-bearing member and the sub-pressure-bearing member are rotated and unfolded, the bottom surface of the side plate in the main pressure-bearing member and the bottom surface of the side plate in the sub-pressure-bearing member are flush. The horizontal plate and the side plate in the main pressure-bearing member are respectively a pressure-bearing horizontal plate and a pressure-bearing side plate, and at least two pressure-bearing side plates are spaced apart on the bottom surface of the pressure-bearing horizontal plate.

[0012] In some embodiments, the horizontal plate and the side plate in the pressure-bearing components are respectively a transverse pressure-bearing sleeve and a lateral pressure-bearing sleeve. Both the side of the transverse pressure-bearing sleeve and the side of the lateral pressure-bearing sleeve are provided with water-permeable holes. The transverse pressure-bearing sleeve is hinged to one end of the pressure-bearing horizontal plate and has the water storage tank seat inside. In the transverse pressure-bearing sleeve, two sets of water storage volutes are symmetrically arranged on both sides of the water storage tank seat and each includes a plurality of type I volutes and type II volutes arranged at intervals.

[0013] In some embodiments, in the transverse pressure-bearing sleeve, a short pipe is connected to one side of the type I volute and one side of the type II volute, and the short pipe communicates with the upper support section. The width of the transverse pressure-bearing sleeve gradually decreases from the middle to both ends. The transverse pressure-bearing sleeve is provided with the water storage tank seat and two sets of type II volutes that are interconnected inside.

[0014] In some embodiments, a vertical plate is fixed to the top surface of the pressure-bearing horizontal plate, and each set of the two-stage pressure-bearing components further includes a primary hydraulic rod and a secondary hydraulic rod. The two ends of the primary hydraulic rod are respectively fixedly connected to the sliding plate and the pressure-bearing horizontal plate, and the two ends of the secondary hydraulic rod are respectively hinged to the vertical plate and the transverse pressure-bearing sleeve.

[0015] In some embodiments, the translational power assembly includes a hollow cylinder fixed to the bottom of the slide block. A motor is fixed to a first end of the hollow cylinder. The output shaft of the motor extends movably into the interior of the hollow cylinder and is connected to a screw. The end of the screw opposite to the motor is movably connected to the inner wall of the second end of the hollow cylinder. The screw is connected to the slide block drive.

[0016] In some embodiments, the translational force assembly further includes a moving block and a connecting rod. The moving block is slidably fitted into the cavity of the hollow cylinder and has a threaded hole that engages with the screw thread. The bottom wall of the hollow cylinder has a strip-shaped opening. The length direction of the opening is consistent with the axial direction of the screw and the length direction of the slide plate. The first end of the connecting rod passes through the opening and is connected to the moving block, and the second end of the connecting rod is connected to the slide plate.

[0017] In some embodiments, the anchor drilling rig further includes an adjusting arm mechanism and a drill rod mechanism connected to each other. The adjusting arm mechanism includes a support seat mounted on the workbench. A first hydraulic cylinder and a second hydraulic cylinder are fixedly spaced at the upper end of the support seat. A primary boom is connected to the top of the first hydraulic cylinder and the top of the second hydraulic cylinder.

[0018] In some embodiments, the primary boom includes a first rod segment and a second rod segment fixedly connected to each other. The first rod segment is hinged to the top of the first cylinder and the top of the second cylinder. A third cylinder is connected to the protrusion of the second rod segment. A secondary boom is hinged to the top of the second rod segment and the top of the third cylinder. The drill rod mechanism is fixed to the upper side of the secondary boom.

[0031] Embodiments of the present invention are described in detail below, with examples of the embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1-11 As shown, the rock bolt drilling rig for roadway slope support based on water-rich characteristics according to an embodiment of the present invention includes a track assembly 2 and two sets of balancing mechanisms 1. The balancing mechanism 1 includes a sliding plate 3, a sliding groove seat 4, a translational force assembly 5, and two sets of two-stage pressure-bearing assemblies 6.

[0033] The two-stage pressure-bearing components 6 of the anchor drilling rig can extend and retract vertically and contact the ground. The translational force component 5 can drive the slide plate 3 together with the two-stage pressure-bearing components 6 to translate along the length of the slide seat 4, so as to adjust the contact position between the additional structure and the ground without changing the position of the drilling rig.

[0034] Specifically, two sets of balancing mechanisms 1 are symmetrically arranged on both sides of the track assembly 2, such as... Figure 3 As shown, the slide plate 3 is movably installed inside the slide rail seat 4. The sliding direction of the slide plate 3 is the same as the moving direction of the track assembly 2. Please refer to... Figure 6 The translational force component 5 is installed at the bottom of the slide seat 4 and is connected to the slide plate 3 via transmission. Two sets of two-stage pressure-bearing components 6 are arranged at intervals along the length of the slide plate 3. Each set of two-stage pressure-bearing components 6 is movably connected to the slide plate 3 in the vertical direction. Each set of two-stage pressure-bearing components 6 includes a main pressure-bearing component 61 and a sub-pressure-bearing component 62 that are rotatably connected. When the anchor drilling rig starts working, the sub-pressure-bearing component 62 gradually unfolds relative to the main pressure-bearing component 61, and the two-stage pressure-bearing components 6 move vertically to contact the ground. The main pressure-bearing component 61 and the sub-pressure-bearing component 62 both include a horizontal plate and at least two side plates set on the bottom surface of the horizontal plate. Each horizontal plate and each side plate in the sub-pressure-bearing component 62 includes a water storage tank seat 63 and two sets of water storage volutes that are interconnected. The water storage tank seat 63 is arranged in a T-shape in the vertical direction and includes an upper support section 631 and a lower support section 632. The lower support section 632 is arranged in a strip shape.

[0035] Therefore, the two sets of balancing mechanisms 1, as auxiliary stabilizing structures, can contact the ground and transmit loads to the ground, thereby improving the gripping stability of the drilling rig during operation. The main bearing component 61 and the sub-bearing component 62 can increase the contact area with the ground after unfolding. When the water-rich soil slope pavement is compressed, water in the soil is exuded and enters the water storage tank 63 along the water storage volute, separating from the soil particles on the outer surface of the two-stage bearing components 6, preventing excessive water from local concentration and causing local overturning of the compressed soil. The water storage tank 63 includes a strip-shaped lower support section 632, which can collect and store some of the exuded water. When the sub-bearing component 62 rotates around the main bearing component 61 and retracts, the water in the water storage tank 63 can be discharged from the permeable holes provided on the side of the sub-bearing component 62.

[0036] The two-stage bearing components 6 can extend and retract vertically. Without changing the position of the anchor drilling rig, the sliding plate 3, driven by the translational force component 5, can move the two-stage bearing components 6 along the length of the sliding seat 4, thereby adjusting the contact position between the two-stage bearing components 6 and the ground along the length of the track component 2. In cases where the width of the road surface at the bottom of the slope is narrow and it is not possible to install hydraulic support components that extend in all directions, it is understandable that by moving the two-stage bearing components 6, the contact position between the main bearing component 61 and the sub-bearing component 62 and the road surface soil can be adjusted without changing the position of the anchor drilling rig. Moreover, each of the two sets of two-stage bearing components 6 corresponds to a translational force component 5, which can achieve individual control.

[0037] In some embodiments, such as Figure 1 As shown, the anchor drilling rig also includes a worktable 7, on which a positioning plate 71 is installed. Two sets of track assemblies 2 are provided, and the two sets of track assemblies 2 are symmetrically distributed about the centroid of the positioning plate 71, as shown below. Figure 3 As shown, the slide plate 3 and the slide seat 4 correspond one-to-one. The two slide seats 4 are respectively installed at both ends of the positioning plate 71. It can be understood that under the drive of the translational force component 5, each slide plate 3 slides along the inner wall of the corresponding slide seat 4, thereby changing the position of the two-stage pressure-bearing components 6 connected to the slide plate 3, and realizing the translational adjustment of the contact position between the two-stage pressure-bearing components 6 and the ground.

[0038] Please refer to Figure 3 , Figure 4 and Figure 5 Each slide plate 3 corresponds to a slide seat 4. The sliding adjustment of the two slide plates 3 along the length of the slide seat 4 is independent of each other. Therefore, the operator can adjust the two slide plates 3 separately as needed, making the adjustment of the two sets of two-stage pressure-bearing components 6 along the side of the anchor drilling machine more flexible.

[0039] like Figure 2As shown, the anchor drilling rig operates on the road surface c at the bottom of the slope, including a moving phase and an operating phase. During the moving phase, the anchor drilling rig moves along the travel direction a on the road surface c at the bottom of the slope. After moving to each anchoring area corresponding to the slope b, the anchor drilling rig stops and enters the operating phase. During the operating phase, the anchor drilling rig performs anchor drilling at predetermined locations on the slope b. During anchor drilling, the anchor drilling rig generates a vibration load, which is transmitted to the road surface c at the bottom of the slope through the anchor drilling rig body. The anchor drilling rig maintains stability by relying on its two sets of track assemblies 2 to maintain stable contact with the road surface. The road surface in contact with the anchor drilling rig is subjected to load. Loading can cause local depressions and settlements, and water in the soil can seep out from between soil particles, exacerbating the muddyness of the road surface. The soil in the affected local area of ​​the road surface will gradually deepen, and may even cause local soil overturning, thereby affecting the stability of the anchor drilling rig and the accuracy of the anchor drilling. In addition, since the width of the road surface c at the bottom of the slope is relatively narrow, it is not suitable to install hydraulic outriggers that extend in all directions on the drilling rig to help improve the stability of the anchor drilling rig during operation. It is understandable that by translating the two-stage pressure-bearing components 6, the stability of the anchor drilling rig when operating on water-rich soil slopes can be specifically improved.

[0040] In some embodiments, when the main bearing member 61 and the sub-bearing member 62 are rotated and unfolded, the bottom surface of the side plate in the main bearing member 61 and the bottom surface of the side plate in the sub-bearing member 62 are flush. It can be understood that after the main bearing member 61 and the sub-bearing member 62 are rotated and unfolded, they can contact the soil of the road surface c at the bottom of the slope as a whole. By increasing the contact area with the soil, the adverse effects on the road surface c at the bottom of the slope are reduced. The horizontal plate and the side plate in the main bearing member 61 are respectively the bearing horizontal plate 611 and the bearing side plate 612, and at least two bearing side plates 612 are spaced apart on the bottom surface of the bearing horizontal plate 611.

[0041] Optionally, the pressure-bearing horizontal plate 611 and the pressure-bearing side plate 612 are configured as solid pressure plates, which have high rigidity.

[0042] In some embodiments, such as Figure 6 As shown, the horizontal plate and side plate in the pressure-bearing component 62 are respectively the transverse pressure-bearing sleeve 621 and the lateral pressure-bearing sleeve 622. The transverse pressure-bearing sleeve 621 is hinged to one end of the pressure-bearing horizontal plate 611 and has a water storage tank seat 63 inside. In the transverse pressure-bearing sleeve 621, two sets of water storage spiral shells are symmetrically arranged on both sides of the water storage tank seat 63 and each includes multiple type I spiral shells 623 and type II spiral shells 624 arranged at intervals. It can be understood that the type I spiral shells 623 and type II spiral shells 624 can store water to a certain extent and prevent water from overflowing again. In the transverse pressure-bearing sleeve 621, a short pipe 625 is connected to one side of the type I spiral shell 623 and one side of the type II spiral shell 624, and the short pipe 625 is connected to the upper support section 631.

[0043] In some embodiments, such as Figure 8As shown, the width of the lateral pressure-bearing sleeve 622 gradually decreases from the middle to both ends. The lateral pressure-bearing sleeve 622 is provided with interconnected water storage tank seats 63 and two sets of type II volutes 624. Water permeable holes are opened on the side of the transverse pressure-bearing sleeve 621 and the side of the lateral pressure-bearing sleeve 622. It can be understood that the water that seeps out of the soil due to pressure enters the transverse pressure-bearing sleeve 621 and the lateral pressure-bearing sleeve 622 through the water permeable holes, and is then partially placed in type I volutes 623 and / or type II volutes 624, and enters the water storage tank seat 63 through the short pipe 625. This can separate the water in the soil from the soil particles to a certain extent, and prevent excessive water from local concentration and causing local overturning of the pressure-bearing soil.

[0044] In some embodiments, such as Figure 6 As shown, a vertical plate is fixed to the top surface of the pressure-bearing horizontal plate 611. Each set of two-stage pressure-bearing components 6 also includes a primary hydraulic rod 64 and a secondary hydraulic rod 65. The two ends of the primary hydraulic rod 64 are fixedly connected to the sliding plate 3 and the pressure-bearing horizontal plate 611, respectively. The two ends of the secondary hydraulic rod 65 are hinged to the vertical plate and the transverse pressure-bearing sleeve 621, respectively. It can be understood that during the extension and retraction of the secondary hydraulic rod 65, the transverse pressure-bearing sleeve 621 gradually rotates relative to the pressure-bearing horizontal plate 611, and can make the transverse pressure-bearing sleeve 621 flush with the pressure-bearing horizontal plate 611 and apply load to the ground as a whole. In addition, the extension and retraction of the primary hydraulic rod 64 can drive the main pressure-bearing component 61 and the sub-pressure-bearing component 62 to move vertically.

[0045] In some embodiments, such as Figure 6 As shown, the translational motion assembly 5 includes a hollow cylinder 51 fixed to the bottom of the slide seat 4. A motor 52 is fixed to the first end of the hollow cylinder 51. The output shaft of the motor 52 extends movably into the interior of the hollow cylinder 51 and is connected to a screw 53. The end of the screw 53 opposite to the motor 52 is movably connected to the inner wall of the second end of the hollow cylinder 51. It can be understood that during the operation of the motor 52, the motor 52 drives the screw 53 to rotate inside the hollow cylinder 51.

[0046] In some embodiments, such as Figure 6As shown, the translational force assembly 5 also includes a movable block 511 and a connecting rod 512. The movable block 511 is slidably fitted into the cavity of the hollow cylinder 51 and is provided with a threaded hole that is threadedly engaged with the screw 53. The bottom wall of the hollow cylinder 51 is provided with a strip-shaped opening. The length direction of the opening, the axial direction of the screw 53, and the length direction of the slide plate 3 are consistent. The first end of the connecting rod 512 passes through the opening and is connected to the movable block 511. The second end of the connecting rod 512 is connected to the slide plate 3. It can be understood that since the movable block 511 is provided with a threaded hole that is threadedly engaged with the screw 53, during the rotation of the screw 53, the movable block 511 moves against the inner wall of the hollow cylinder 51, causing the movable block 511 to translate inside the hollow cylinder 51 and drive the connecting rod 512 to translate. Since the connecting rod 512 is connected to the slide plate 3, the slide plate 3 is driven to translate along the length direction of the slide seat 4, thereby driving the two-stage pressure-bearing assembly 6 connected to the slide plate 3 to translate.

[0047] Optionally, the translational force component 5 can also be driven by a hydraulic cylinder to directly drive the slide plate 3 to translate along the length of the slide seat 4.

[0048] In some embodiments, such as Figure 1 As shown, the anchor drilling rig also includes an adjusting arm mechanism 8 and a drill rod mechanism 9 that are connected to each other. It can be understood that when the anchor drilling rig enters the operation stage, the slope b is anchored through the drill rod mechanism 9. In order to ensure the anchor drilling accuracy, the anchor drilling rig should remain relatively stable with the slope b throughout the operation stage, and the anchor drilling rig should not have large displacement.

[0049] In some embodiments, such as Figure 10 As shown, the adjusting arm mechanism 8 includes a support base 81 mounted on the workbench 7. A first hydraulic cylinder 82 and a second hydraulic cylinder 83 are fixedly spaced at the upper end of the support base 81. A primary boom 84 is connected to the top of the first hydraulic cylinder 82 and the top of the second hydraulic cylinder 83. The primary boom 84 includes a first rod segment 841 and a second rod segment 842 fixedly connected to each other. The first rod segment 841 is hinged to the top of the first hydraulic cylinder 82 and the top of the second hydraulic cylinder 83. It can be understood that the posture of the primary boom 84 can be adjusted by controlling the first hydraulic cylinder 82 and the second hydraulic cylinder 83. Figure 11 As shown, the protrusion of the second rod segment 841 is connected to the third hydraulic cylinder 85. The top of the second rod segment 841 and the top of the third hydraulic cylinder 85 are hinged to the secondary boom 86. The drill rod mechanism 9 is fixed to the upper side of the secondary boom 86. It can be understood that by adjusting the third hydraulic cylinder 85, the posture of the secondary boom 86 can be controlled, so that the adjusting arm mechanism 8 has a high degree of flexibility.

[0050] The following description, with reference to the accompanying drawings, describes an anchor drilling rig for roadway slope support based on water-rich characteristics according to an embodiment of the present invention.

[0051] like Figures 1-11As shown, the anchor drilling rig includes a track assembly 2, two sets of balancing mechanisms 1, a worktable 7, an adjusting arm mechanism 8, and a drill rod mechanism 9. The two sets of balancing mechanisms 1 are symmetrically arranged on both sides of the track assembly 2. As auxiliary stabilizing structures, the two sets of balancing mechanisms 1 can contact the ground and transmit loads to the ground, thereby improving the grip stability of the drilling rig during operation. Each set of balancing mechanisms 1 includes a sliding plate 3, a sliding seat 4, a translational force assembly 5, and two sets of two-stage pressure-bearing assemblies 6. The sliding plate 3 is movably installed inside the sliding seat 4. The sliding direction of the sliding plate 3 is consistent with the moving direction of the track assembly 2. The translational force assembly 5 adopts a hydraulic cylinder that is connected to the sliding plate 3. The hydraulic cylinder can drive the sliding plate 3 to translate along the length of the sliding seat 4, thereby driving the two-stage pressure-bearing assemblies 6 connected to the sliding plate 3 to translate. The two sets of translational force assemblies 5 respectively control the movement of one set of two-stage pressure-bearing assemblies 6.

[0052] Each set of two-stage pressure-bearing components 6 is vertically and movably connected to the sliding plate 3. The two-stage pressure-bearing components 6 include a main pressure-bearing component 61 and a secondary pressure-bearing component 62 that are rotatably connected. The main pressure-bearing component 61 includes a pressure-bearing horizontal plate 611 and a pressure-bearing side plate 612. The secondary pressure-bearing component 62 includes a transverse pressure-bearing sleeve 621 and a lateral pressure-bearing sleeve 622. Both the transverse pressure-bearing sleeve 621 and the lateral pressure-bearing sleeve 622 have water-permeable holes on their sides and are internally equipped with interconnected water storage tanks 63 and water storage spirals. The shell and water storage tank 63 are arranged in a T-shape along the vertical and include an upper support section 631 and a lower support section 632. The lower support section 632 is arranged in a strip shape and can stably store water. Water that seeps out of the soil due to pressure enters the transverse pressure shell 621 and the lateral pressure shell 622 through the water permeable holes, and is then partially placed in the water storage shell and the water storage tank 63. This can separate the water in the seeping soil from the soil particles to a certain extent and prevent excessive water from local concentration that could cause local overturning of the pressure soil.

[0053] A vertical plate is fixed to the top surface of the pressure-bearing horizontal plate 611. Each set of two-stage pressure-bearing components 6 also includes a primary hydraulic rod 64 and a secondary hydraulic rod 65. The two ends of the primary hydraulic rod 64 are fixedly connected to the sliding plate 3 and the pressure-bearing horizontal plate 611, respectively. The two ends of the secondary hydraulic rod 65 are hinged to the vertical plate and the transverse pressure-bearing sleeve 621, respectively. During the extension and retraction of the secondary hydraulic rod 65, the transverse pressure-bearing sleeve 621 gradually rotates relative to the pressure-bearing horizontal plate 611, and can make the transverse pressure-bearing sleeve 621 flush with the pressure-bearing horizontal plate 611 and act as a whole to apply pressure to the ground. During the extension and retraction of the primary hydraulic rod 64, the main bearing component 61 and the secondary bearing component 62 gradually move vertically. After the main bearing component 61 and the secondary bearing component 62 come into contact with the ground, the magnitude of the load applied to the ground by the primary hydraulic rod 64 can be changed by fine adjustment. After a certain operation stage of the anchor drilling rig is completed, the secondary hydraulic rod 65 retracts and drives the secondary bearing component 62 to rotate. During the rotation of the secondary bearing component 62, the water in the water storage tank seat 63 and the water storage volute can be discharged from the water permeable hole.

[0054] The anchor drilling rig in this application can flexibly adjust the contact position between the two-stage bearing components 6 and the ground without changing the drilling rig position, taking into account the narrow road surface c at the bottom of the slope and the high water content of the soil in the road surface c at the bottom of the water-rich soil slope. It also prevents the soil in the contact area from sinking deeper due to the concentration of water and the superposition of loads, thus ensuring the stability of the drilling rig during operation.
