Description

Technical Field

[0001] This invention belongs to the field of drilling rig technology, specifically relating to an automated hydraulic drilling rig for mining. Background Technology

[0002] In engineering fields such as mining, tunneling, and culvert construction, hydraulic drilling rigs, through their power unit, hydraulic system, traveling mechanism, drill frame equipped with a thruster, outrigger, and drill rod connection / disconnection device, can achieve hydraulic rock drilling. In related technologies, operators can use a controller to move the drilling rig. After the rig reaches the working position, by adjusting the attitude of the rig and drill frame, the drill bit and drill rod can perform drilling operations at the desired location.

[0003] However, during actual drilling, when affected by factors such as ground subsidence due to water immersion or vibration, the position of the drilling rig may shift to a certain extent. This will directly cause the drill rod and drill bit to deviate from the preset drilling direction, which will not only directly cause drilling errors, but also generate additional torsional load on the drill bit. As the drilling depth increases, the pressure on the drill bit also increases, which will severely restrict the drilling speed and cause great interference to the accurate survey of geological conditions. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose an automated hydraulic drilling rig for mining, which can adaptively adjust the position of the drilling rig during the drilling process, ensuring that the rig maintains high-precision positioning during drilling operations and completing the drilling work.

[0046] Embodiments of the present invention are described in detail below, examples of which are 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.

[0047] like Figures 1 to 7As shown, an embodiment of the present invention provides a mining automated hydraulic drilling rig 100, which includes a chassis 10, a drilling rig adjustment device 30, an inclination adjustment device 50, and a drilling device 70. A tracked bicycle 11 is provided below the chassis 10. The drilling rig adjustment device 30 includes multiple independent positioning support plates 31, which are located around the chassis 10 and connected to the chassis 10. The positioning support plates 31 are used to abut against the ground and are vertically movable relative to the chassis 10 to position and adjust the attitude of the chassis 10. The inclination adjustment device 50 includes a drilling slide plate 51 and an adjustment component 52. The adjustment component 52 is located between the drilling slide plate 51 and the chassis 10 and is used to adjust the inclination angle and height of the drilling slide plate 51 relative to the chassis 10. The drilling device 70 is located on the drilling slide plate 51 and is used to connect the drill rod and drive the drill rod to move.

[0048] Specifically, the drilling rig adjustment device 30 includes multiple independent and height-adjustable positioning support plates 31, which are cleverly distributed around the chassis 10 and tightly connected to it. Each positioning support plate 31 has the ability to directly contact the ground. By precisely controlling the vertical movement of these support plates, not only can the chassis 10 and the entire drilling rig be accurately positioned, but the height of various parts on the chassis 10 can also be flexibly adjusted according to actual needs. This function is crucial for dealing with complex terrain conditions, maintaining the stability of the drilling rig, and accurately adjusting the drill rod inclination angle. Especially when facing adverse factors such as ground subsidence or vibration, the drilling rig adjustment device 30 can respond quickly to ensure that the drill rod and drill bit always remain in the preset drilling direction, thereby effectively improving the accuracy and efficiency of drilling operations.

[0049] Furthermore, the tilt adjustment device 50 further enhances the flexibility of the drilling rig. It mainly consists of a drilling slide plate 51 and a precision adjustment assembly 52. ​​The adjustment assembly 52 is cleverly positioned between the drilling slide plate 51 and the chassis 10. Through its precise adjustment function, the tilt angle and height of the drilling slide plate 51 relative to the chassis 10 can be easily adjusted. This design allows the drilling rig 70 to flexibly adjust the tilt angle of the drill rod according to different geological conditions and drilling requirements, thereby ensuring that drilling operations can be carried out in the optimal posture, further improving drilling efficiency and success rate.

[0050] In addition, a tracked bicycle 11 is installed under the chassis 10 to ensure that the drilling rig can move stably and turn flexibly in complex and varied terrain, greatly enhancing the accessibility and adaptability of the work area. It should be noted that the tracked self-propelled vehicle is a commonly used self-propelled device on hydraulic drilling rigs, and the specific walking method and structure will not be described in detail here.

[0051] In summary, the automated hydraulic drilling rig 100 for mining provided in this embodiment of the invention achieves a dual adjustment mechanism for the drill rod through the drilling rig adjustment device 30 and the tilt adjustment device 50, which can improve the accuracy and flexibility of drilling operations. Especially in complex environments such as ground subsidence or vibration, it can ensure that the drill rod and drill bit maintain the preset drilling direction.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the drilling rig adjustment device 30 includes a horizontal adjustment component 32 and a vertical adjustment component 34. The horizontal adjustment component 32 includes a positioning cylinder 321 and a positioning rod 322. The positioning cylinder 321 extends along the horizontal direction of the chassis 10, and the positioning rod 322 is slidably disposed inside the positioning cylinder 321. The vertical adjustment component 34 includes a first positioning hydraulic cylinder 341 and a universal joint 342. The first positioning hydraulic cylinder 341 is connected to the positioning rod 322, and the universal joint 342 is connected between the output end of the first positioning hydraulic cylinder 341 and the positioning support plate 31. The vertical adjustment component 34 and the positioning support plate 31 are arranged in a one-to-one correspondence.

[0053] Specifically, the positioning cylinder 321 extends horizontally along the chassis 10, providing a stable and precise sliding track for the positioning rod 322. The positioning rod 322 slides within the positioning cylinder 321, allowing free movement in the horizontal direction. This helps the drilling rig quickly find suitable support positions in complex terrain and maintains the stability of the chassis 10 during drilling, ensuring smooth drilling operations. The vertical adjustment assembly 34 consists of a first positioning hydraulic cylinder 341 and a universal joint 342. Each set of vertical adjustment assemblies 34 corresponds one-to-one with a positioning support plate 31, ensuring the drilling rig's precise vertical adjustment capability.

[0054] The first positioning hydraulic cylinder 341, serving as the power source, is closely connected to the positioning rod 322. Through its powerful thrust or pull, it can precisely control the vertical movement of the positioning support plate 31. The universal joint 342 connects the output end of the first positioning hydraulic cylinder 341 and the positioning support plate 31. It can not only withstand the enormous force from the hydraulic cylinder but also provide flexible connections in multiple directions, making the vertical movement of the positioning support plate 31 more stable and reliable.

[0055] During operation, the position of the positioning rod 322 within the positioning cylinder 321 is first adjusted, causing the vertical adjustment assembly 34 and the positioning support plate 31 to move on the horizontal plane of the chassis 10, thereby driving a suitable support plane. Subsequently, the vertical adjustment assembly 34 begins to work, precisely adjusting the height of the positioning support plate 31 in the vertical direction of the chassis 10 through the telescopic movement of the first positioning hydraulic cylinder 341. This achieves precise adjustment of the attitude of the drilling rig chassis 10, ensuring not only the stability and flexibility of the drilling rig in complex terrain but also greatly improving the accuracy and efficiency of drilling operations.

[0056] In some embodiments, the plurality of vertical adjustment components 34 are symmetrically arranged in pairs on both sides of the chassis 10. The horizontal adjustment component 32 further includes a bidirectional adjusting screw 323, an adjusting motor 324, and two adjusting nut sets 325. The adjusting motor 324 is drivenly connected to the bidirectional adjusting screw 323, which is rotatably disposed within the positioning cylinder 321. The adjusting nut sets 325 are threadedly connected to the bidirectional adjusting screw 323, and are arranged in a one-to-one correspondence with the vertical adjustment components 34, and are connected to the vertical adjustment components 34. In this embodiment, the adjusting nut sets 325 are connected to the positioning rod 322, thereby enabling the adjusting nut sets 325 to drive the vertical adjustment components 34 to move.

[0057] Furthermore, the horizontal adjustment assembly 32 also includes an adjustment lever 326, an adjustment turbine 327, and an adjustment worm gear 328. The output end of the adjustment motor 324 is connected to the adjustment lever 326. The adjustment worm gear 328 is connected to and coaxially arranged with the adjustment lever 326. The adjustment turbine 327 meshes with the adjustment worm gear 328. The adjustment turbine 327 is mounted on the bidirectional adjustment lead screw 323, and the adjustment turbine 327 and the bidirectional adjustment lead screw 323 are arranged in a one-to-one correspondence. It is conceivable that in some embodiments, the adjustment worm gear 328 and the adjustment lever 326 can be configured as a single unit.

[0058] Optionally, the adjusting turbine 327 is located at the middle position of the bidirectional adjusting screw 323.

[0059] Furthermore, the positioning cylinder 321 extends along the left and right direction of the chassis 10, and there are two positioning cylinders 321. The two positioning cylinders 321 are spaced apart in the front and rear direction of the chassis 10. There are four positioning support plates 31 and four vertical adjustment components 34.

[0060] In some embodiments, the positioning rod 322 is provided with a positioning slide plate 329, and the positioning slide plate 329 is provided with a first positioning groove 3291. The first positioning hydraulic cylinder 341 drives the positioning support plate 31 to move so that the positioning support plate 31 is moved out or received into the first positioning groove 3291. The chassis 10 is provided with a second positioning groove 12. The adjusting nut group 325 drives the positioning rod 322 to move so that the positioning slide plate 329 is moved out or received into the second positioning groove 12, thereby realizing the storage of the positioning support plate 31 and ensuring that the positioning support plate 31 is received into the second positioning groove 12 of the chassis 10.

[0061] In this embodiment, the positioning cylinder 321 extends along the left-right direction of the chassis 10. Positioning grooves are provided on both sides of the positioning cylinder 321, and a positioning rod 322 is slidably disposed within each positioning groove. Optionally, the positioning rod 322 can be a hexagonal tube, passing through and slidably disposed within the positioning groove. The adjusting nut assembly 325 is connected to the positioning rod 322. One end of the bidirectional adjusting screw 323 is movably inserted into the positioning rod 322, and the positioning slide plate 329 is disposed at the end of the positioning rod 322 away from the adjusting nut assembly 325.

[0062] During construction, the operator can move the drilling rig to the designated drilling position by manipulating the tracked bicycle 11, start the adjustment motor 324, the output end of the adjustment motor 324 drives the adjustment rod 326 to rotate, the adjustment rod 326 drives the adjustment turbine 327 and the adjustment worm gear 328 to rotate, the adjustment worm gear drives the bidirectional adjustment screw 323 to rotate, so that the adjustment nut group 325 on the bidirectional adjustment screw 323 drives the positioning rod 322 connected to it to move away from the center of the chassis 10, the positioning rod 322 drives the positioning slide plate 329 to move out of the second positioning groove 12, so that the vertical adjustment components 34 are distributed around the chassis 10. Then the first positioning hydraulic cylinder 341 is started, the output end of the first positioning hydraulic cylinder 341 drives the universal joint 342 and the positioning support plate 31 to move, under the adaptive adjustment of the universal joint 342, the positioning support plate 31 is firmly in contact with the ground. In other words, by controlling the extension of the four first positioning hydraulic cylinders 341, the drilling rig can be leveled to prevent the drill rod and drill bit from deviating from the preset drilling direction.

[0063] like Figure 1 and Figure 4As shown, in some embodiments, the positioning component 52 includes a positioning frame 521, an angle adjustment mechanism 54, and an inclination monitor 522. The positioning frame 521 is mounted on the chassis 10. The angle adjustment mechanism 54 is located between the positioning frame 521 and the drilling slide plate 51. There are two sets of angle adjustment mechanisms 54, which are spaced apart. The inclination monitor 522 is mounted on the drilling slide plate 51. The inclination monitor 522 is used to monitor the inclination angle of the drilling slide plate 51 and adjust the operation of the angle adjustment mechanism 54 according to the inclination angle, so as to realize real-time monitoring and precise control of the drilling process.

[0064] Specifically, the positioning frame 521, as the supporting foundation of the entire system, provides a solid platform for subsequent adjustments and monitoring, ensuring the stability and reliability of the positioning component 52 in complex working environments. The angle adjustment mechanism 54, located between the positioning frame 521 and the drilling slide plate 51, not only adjusts the angle of the drilling slide plate 51 relative to the positioning frame 521 but also directly affects the accuracy and efficiency of drilling operations. In particular, this embodiment provides two sets of angle adjustment mechanisms 54, arranged at intervals, ensuring both adjustment flexibility and enhanced structural stability and load-bearing capacity. This dual-protection design undoubtedly provides a more precise and reliable adjustment method for drilling operations.

[0065] The tilt monitor 522 may include a tilt sensor, which can monitor the tilt angle of the drilling slide 51 in real time to ensure that the drilling operation can proceed according to the predetermined trajectory and angle. Once the tilt monitor 522 detects a deviation in the tilt angle, it will immediately activate the adjustment mechanism, and quickly and accurately correct the attitude of the drilling slide 51 by precisely controlling the operation of the angle adjustment mechanism 54. This process not only realizes real-time monitoring and precise control of the drilling operation, but also greatly improves the safety and efficiency of the operation.

[0066] Furthermore, two sets of angle adjustment mechanisms 54 are spaced apart along the front-rear direction of the chassis 10. The angle adjustment mechanism 54 includes an adjustment hydraulic cylinder 541, an adjustment connecting rod 542, and an adjustment cylinder 543. The adjustment hydraulic cylinder 541 is located on the adjustment frame 521. The output end of the adjustment hydraulic cylinder 541 has an adjustment seat 544. One of the adjustment seat 544 and the adjustment cylinder 543 is fixedly connected to the adjustment connecting rod 542, and the other of the adjustment seat and the adjustment cylinder 543 is rotatably connected to the adjustment connecting rod 542. The rotation axis of the adjustment connecting rod 542 is located in the left-right direction of the chassis 10. In other words, one of the adjusting cylinder 543 and the adjusting connecting rod 542 is fixedly connected to the adjusting seat, while the other is connected to the adjusting cylinder 543 or the adjusting seat through a rotatable connection method (such as a bearing or hinge), so that the adjusting connecting rod 542 can rotate freely along the rotation axis in the left-right direction of the chassis 10, thereby realizing the tilt adjustment of the drilling slide plate 51 in the front-back direction.

[0067] In this embodiment, after the drilling rig adjustment device 30 moves the drilling rig to the designated drilling position, the adjusting hydraulic cylinders 541 in the two sets of angle adjustment mechanisms 54 are simultaneously activated according to the position to be drilled. The height of the drilling slide plate 51 is adjusted by moving the output end of the adjusting hydraulic cylinder 541. If the angle of the drilling slide plate 51 needs to be adjusted, one of the two adjusting hydraulic cylinders 541 can be activated or the two adjusting hydraulic cylinders 541 can be controlled to move asynchronously. Of course, it is conceivable that the operator can also adjust the tilt of the chassis 10 through the first positioning hydraulic cylinder 341 to achieve dual adjustment of the drilling slide plate 51, which can control the drilling slide plate 51 to offset within a range of ±60°.

[0068] like Figure 1 and Figure 5 As shown, in some embodiments, the drilling device 70 includes a lead screw 711, a lead slide 712, and a drilling motor 713. The lead screw 711 is rotatably mounted on the drilling slide plate 51, and a lead nut assembly 714 is threadedly connected to the lead screw 711. The lead slide 712 is connected to the lead nut assembly 714, and a drill pipe connecting assembly 73 is provided on the lead slide 712 for connecting the drill pipe. During operation, the operator can start the drilling motor 713. The output end of the drilling motor 713 drives the lead screw 711 to move, causing the lead screw 711 to move the lead nut assembly 714 and the lead slide 712. The lead slide 712 then drives the drill pipe connecting assembly 73 and the drill pipe to move synchronously.

[0069] Furthermore, the drill pipe connection assembly 73 includes a connection frame 731, a transmission assembly 732, and a power motor 733. The connection frame 731 is mounted on the feed slide 712, and a power sleeve 734 is rotatably mounted on the connection frame 731 for connecting the drill pipe and the water source. The transmission assembly 732 includes a meshing power worm gear 7321 and a power worm 7322. The power worm gear 7321 is mounted on the power sleeve 734, and the power worm 7322 is rotatably mounted on the connection frame 731. The power motor 733 is mounted on the connection frame 731, and the output end of the power motor 733 is connected to the power worm 7322.

[0070] In this embodiment, the drill pipe connection assembly 73 further includes a water inlet frame 735, a water inlet pipe 736, and a drill pipe power head 737. The water inlet pipe 736 can be fixed to the connection frame 731 through the water inlet frame 735. The water inlet pipe 736 is connected to the power sleeve 734. The drill pipe power head 737 and the water inlet pipe 736 are respectively located on both sides of the power sleeve 734. During operation, the operator can start the power motor 733. The output end of the power motor 733 can drive the power worm gear 7322 and the power worm wheel 7321 to run. The power worm wheel 7321 can drive the power sleeve 734 to rotate, thereby causing the power sleeve 734 to drive the drill pipe power head 737 and the drill pipe to rotate. Furthermore, during the drilling process, the water inlet pipe 736 can be connected to an external mud pump, which can transport the mud required for drilling along the water inlet pipe 736, the power casing 734, and the drill rod power head 737 to the drill rod and the drill bit, thus realizing the drilling operation.

[0071] like Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments, the drilling device 70 further includes a positioning frame 75 and two positioning mechanisms 77. The positioning frame 75 is disposed on the drilling slide plate 51. The two positioning mechanisms 77 are symmetrically arranged on the positioning frame 75. Each positioning mechanism 77 includes a second positioning hydraulic cylinder 771, an arc-shaped positioning frame 772, and positioning rollers 773. The second positioning hydraulic cylinder 771 is disposed on the positioning frame 75, and its output end is connected to the arc-shaped positioning frame 772. Multiple positioning rollers 773 are provided, and the multiple positioning rollers 773 are arc-shaped and arranged at equal angles on the arc-shaped positioning frame 772.

[0072] The two positioning mechanisms 77 are symmetrically distributed on the positioning frame 75. This layout not only helps maintain balance during drilling but also effectively disperses forces, reduces the load on individual components, and improves the overall structural durability. The second positioning hydraulic cylinder 771 serves as the power source, with its output end tightly connected to the arc-shaped positioning frame 772. By precisely controlling the extension and retraction of the hydraulic cylinder, the position and angle of the arc-shaped positioning frame 772 can be flexibly adjusted to accommodate drill rods or drill bits of different diameters and shapes, ensuring a close fit and stable support during drilling operations.

[0073] The arc-shaped positioning frame 772's arc profile perfectly matches the outer periphery of the drill pipe or drill bit, providing all-around support and positioning. Multiple positioning rollers 773 are evenly spaced on the arc-shaped positioning frame 772. These rollers not only reduce friction between the drill pipe or drill bit and the positioning frame but also further improve positioning flexibility and accuracy through their rolling action. The synergistic effect of the multiple positioning rollers 773 ensures that any minor deviations during drilling can be quickly and effectively corrected, thus guaranteeing the smooth progress of drilling operations.

[0074] Furthermore, the positioning mechanism 77 includes a one-way component 79, which includes a one-way positioning disk 791, a one-way positioning tube 792, and a positioning telescopic block 793. The one-way positioning disk 791 is connected to the positioning roller 773. Multiple trapezoidal limiting grooves 7911 are spaced apart on the outer periphery of the one-way positioning disk 791. The one-way positioning tube 792 is located in the arc-shaped positioning frame 772. The positioning telescopic block 793 is located inside the one-way positioning tube 792. An elastic element 794 is provided between the positioning telescopic block 793 and the one-way positioning tube 792. The positioning telescopic block 793 is movable relative to the one-way positioning tube 792 to extend into or move out of the trapezoidal limiting grooves 7911.

[0075] Specifically, multiple trapezoidal limiting grooves 7911 are carefully arranged at certain intervals on the outer periphery of the one-way positioning disk 791. These limiting grooves can form a stable and reliable fit with the positioning telescopic block 793, thereby achieving locking of the drilling tool at a specific angle and position. The one-way positioning tube 792 can ensure the direction of movement of the positioning telescopic block 793, ensuring that the positioning telescopic block 793 moves smoothly and accurately within it. This not only improves the movement accuracy of the positioning telescopic block 793, but also effectively prevents positioning deviations caused by external forces. Elastic elements 794 are provided between the positioning telescopic block 793 and the one-way positioning tube 792. These elastic elements 794 can not only provide the necessary restoring force for the positioning telescopic block 793, but also absorb and buffer vibrations and impacts during drilling to a certain extent, thereby further improving the stability and durability of the positioning system.

[0076] Optionally, the elastic element 794 can be configured as a spring or elastic rubber.

[0077] Furthermore, the unidirectional positioning disk 791 is provided with multiple trapezoidal positioning blocks 7912, which are equally spaced on the outer periphery of the unidirectional positioning disk 791. A trapezoidal limiting groove 7911 can be formed between two adjacent trapezoidal positioning blocks 7912. When the positioning telescopic block 793 moves along the inner wall of the unidirectional positioning tube 792, it will precisely extend into the trapezoidal limiting groove 7911 and form a tight fit with the trapezoidal positioning block 7912. This not only ensures the stability of the drilling tool in a specific direction, but also absorbs and buffers vibrations and impacts during the drilling process to a certain extent, thereby improving the accuracy and safety of drilling operations.

[0078] Furthermore, the trapezoidal positioning blocks 7912 are arranged according to the principle of equal angles, enabling the unidirectional positioning disk 791 to provide uniform and stable positioning support within a 360-degree range. This means that the drilling tool can be precisely locked and positioned in any direction, thereby greatly expanding the application range and flexibility of the drilling device 70.

[0079] In this embodiment, after the positioning slide plate 329 is fixed in position, the drilling rod with the drilling bit is placed between the two positioning mechanisms 77. The second positioning hydraulic cylinder 771 is then activated simultaneously. The output end of the second positioning hydraulic cylinder 771 drives the arc-shaped positioning frame 772 to move. The arc-shaped positioning frame 772 drives the positioning roller 773 to move, causing multiple positioning rollers 773 to clamp the drilling rod and connect the drilling rod to the drill rod power head 737. During drilling, the drilling rod drives the positioning roller 773 to rotate. The rotation of the positioning roller 773 drives the one-way positioning disk 791 to rotate. The one-way positioning disk 791 drives the trapezoidal positioning block 7912 to move. At this time, after the trapezoidal positioning block 7912 contacts the positioning telescopic block 793, the positioning telescopic block 793 is squeezed into the one-way positioning tube 792 under pressure, without affecting the normal rotation of the positioning roller 773. In other words, the contact between the rotating positioning roller 773 and the drilling rod can fix the position of the drilling rod.

[0080] Furthermore, the multiple positioning rollers 773 can be configured to be inclined, thereby reducing the friction between the drilling rod and the positioning rollers 773 during clockwise rotation and advancement. In addition, the positioning rollers 773 rotate and move along the surface of the drilling rod, and through the contact between the positioning rollers 773 and the drilling rod, the vibration force of the drilling rod during the drilling process can be reduced, and the stability of the drilling rod can be improved.

[0081] In addition, when the drill rod is removed from the drill rod power head 737, the power motor 733 is started to make the drill rod power head 737 move counterclockwise. When the drill rod power head 737 drives the drill rod to rotate counterclockwise, the trapezoidal positioning block 7912 on one side of the positioning roller 773 will engage with the positioning telescopic block 793, so that the positioning roller 773 is stationary to fix its position. By fixing the contact friction between the different positioning rollers 773 and the surface of the drill rod, the drill rod is separated from the drill rod power head 737, and the drill rod is quickly disassembled.

[0082] It should be further explained that during the drilling process, by collecting data on the rotational speed and output power of the propulsion motor 713 and the power motor 733, the density and hardness of the soil layer in the borehole can be identified based on the fluctuations and changes in the collected information. Furthermore, the material in the borehole can be identified by the residue carried out by the mud, thereby realizing the drilling operation. In addition, a hydraulic power system, a central control system, and a manual operating system can be installed on the chassis 10 to enable the start-up and control of the pneumatic equipment.

[0083] During the construction operation of the automated hydraulic drilling rig 100 for mining provided in this embodiment of the invention, the operator can manipulate the tracked self-propelled vehicle to move to the designated drilling position, start the adjustment motor 324, the output end of the adjustment motor 324 drives the adjustment rod 326 to rotate, the rotation of the adjustment rod 326 drives the adjustment worm 328 to rotate, the rotation of the adjustment worm 328 drives the adjustment worm wheel meshing with it to rotate, the rotation of the adjustment worm wheel drives the bidirectional adjustment screw 323 to rotate, so that the adjustment nut group 325 on the bidirectional adjustment screw 323 drives the positioning rod 322 connected to it to move away from the chassis 10. The movement of the positioning rod 322 drives the positioning slide plate 329 to move, and the positioning slide plate 329 drives the first positioning hydraulic cylinder 341 to move. By starting the adjustment motor 324, the four vertical adjustment components 34 are activated. The first positioning hydraulic cylinders 341 are evenly distributed around the tracked self-propelled vehicle. When the first positioning hydraulic cylinders 341 are activated, their output ends drive the universal joint and positioning support plate 31 to move. With the angle adjustment of the universal joint, the positioning support plate 31 is firmly in contact with the ground. By controlling the extension of the output ends of the four positioning hydraulic cylinders, in construction sites with poor flatness, the drilling slide plate 51 can be horizontally aligned by sensing the tilt angle monitor 522. Compared with the traditional independently controlled vertical adjustment components 34, by evenly distributing the vertical adjustment components 34 around the tracked self-propelled vehicle, the positioning speed is not only fast, but also ensures that the drilling slide plate 51 is in the middle position of the four vertical adjustment components 34 after positioning, effectively preventing the drilling slide plate 51 from tilting during drilling.

[0084] Secondly, after fixing the position of the tracked self-propelled vehicle, according to the drilling and drilling position required at the construction site, the two adjusting hydraulic cylinders 541 in the adjusting component 52 are activated simultaneously. The height of the drilling slide plate 51 can be adjusted by the movement of the output end of the adjusting hydraulic cylinder 541. If drilling is required at a specific angle, not only can the tilt angle of the drilling slide plate 51 be adjusted by activating one of the adjusting hydraulic cylinders 541, but also the tilt angle of the drilling slide plate 51 can be adjusted by activating the two first positioning hydraulic cylinders 341 located on the same positioning cylinder 321 simultaneously. The tilt angle of the drilling slide plate 51 can be adjusted by the movement of the output end of the first positioning hydraulic cylinder 341. The above two methods of adjusting the tilt angle of the drilling slide plate 51 can be used in combination to control the movement of the drilling slide plate 51 in the ±60° direction.

[0085] Furthermore, after fixing the position of the positioning slide plate 329, the drill rod with the drill bit installed is placed inside the vertical adjustment assembly 34. Two second positioning hydraulic cylinders 771 are simultaneously activated. The output ends of the second positioning hydraulic cylinders 771 drive the arc-shaped positioning frame 772 to move. The movement of the arc-shaped positioning frame 772 drives the positioning rollers 773 to move, causing the multiple positioning rollers 773 to clamp the drill rod on one side of the drill rod power head 737. Then, the power motor 733 is started. The output end of the power motor 733 drives the power worm gear 7322 to rotate. The rotation of the power worm gear 7322 drives the power worm wheel to rotate. The rotation of the power worm wheel drives the power sleeve 734 to rotate. The drill rod power head 737 rotates clockwise, simultaneously activating the propulsion motor 713. The output of the propulsion motor 713 drives the propulsion screw 711, causing the propulsion nut assembly 714 to move the propulsion slide 712 towards the drilling rod position. The movement of the propulsion slide 712 moves the connecting frame 731, the power sleeve 734, and the drill rod power head 737. Through the clockwise rotation and movement of the drill rod power head 737, it engages with the drilling rod and propels it into the borehole. As the drill rod power head 737 rotates clockwise, the drilling rod contacts the positioning roller 773, causing the positioning roller 773 to rotate. At this time, the rotation of the positioning roller 773... The movement of the unidirectional positioning disk 791 drives the movement of the trapezoidal positioning block 7912. When the trapezoidal positioning block 7912 comes into contact with the positioning telescopic block 793, the positioning telescopic block 793 is squeezed into the unidirectional positioning tube 792 under pressure, without affecting the normal rotation of the positioning roller 773. The position of the drilling rod is fixed through the contact between the rotating positioning roller 773 and the drilling rod. In the actual positioning process, to reduce the friction between the drilling rod and the positioning roller 773 during clockwise rotation and advancement, multiple positioning rollers 773 can be tilted, allowing the positioning rollers 773 to rotate and move along the surface of the drilling rod. The contact between the positioning roller 773 and the drilling rod not only reduces the vibration force of the drilling rod during the drilling process and improves the stability of the drilling rod, but also, when the drilling rod is removed from the drill rod power head 737, the power motor 733 is started to make the drill rod power head 737 move counterclockwise. When the drill rod power head 737 drives the drilling rod to rotate counterclockwise, the trapezoidal positioning block 7912 on one side of the positioning roller 773 will engage with the positioning telescopic block 793, so that the positioning roller 773 is stationary and its position is fixed. By fixing the contact friction between the positioning roller 773 and the surface of the drilling rod, the drilling rod is separated from the drill rod power head 737, and the drilling rod can be quickly disassembled.
