Description

Technical Field

[0001] This utility model relates to the field of drilling machinery, and in particular to a self-propelled fully hydraulic wireline core drilling rig. Background Technology

[0002] Existing equipment for mineral resource exploration and drilling has a low degree of automation, with most work still relying on manual labor. Drilling is labor-intensive and inefficient. Furthermore, existing drilling rigs are large and heavy, making them difficult to transport. Therefore, lightweight core drilling rigs have emerged to adapt to complex terrain, allowing them to be transported to designated locations for operation. However, lightweight core drilling rigs typically only allow exploration of shallow geological layers up to 200-300 meters, making it difficult to drill into deep geological layers or hard rock mining areas. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the existing technology and to propose a self-propelled fully hydraulic wireline core drilling rig, which is easy to move and realizes automatic drilling of deep geological or hard mineral areas.

The top of the drilling rig is equipped with a rope mechanism, the bottom of the drilling rig is equipped with a base mechanism, and the lower part of the drilling rig is connected to the drill rod.

[0006] The top of the drill pipe is connected to the rotary mechanism, which is slidably connected to the turret. The drill pipe passes through the clamping mechanism, which is located below the rotary mechanism and is fixedly mounted on the turret.

[0007] In this utility model, front support legs are provided on the left and right sides of the front end of the frame, and rear support legs are provided on the left and right sides of the rear end of the frame.

[0016] A trunnion is fixed on the cylinder body of the hydraulic cylinder. The trunnion passes through the main body plate and is connected to the hydraulic cylinder limiting sleeve located on the outside of the main body plate. The hydraulic cylinder limiting sleeve is fixedly connected to the main body plate, thereby realizing the limiting of the hydraulic cylinder by the main body plate.

[0017] The inclined sliding plate is provided with a guide plate on the outside away from the drill rod. The inclined sliding plate and the guide plate slide relative to each other. The bottom of the guide plate is fixedly connected to the base plate, and the two sides of the guide plate are fixedly connected to the main body plates on both sides respectively.

[0018] The inclined sliding plate has two parallel limiting guide rails on the inner side facing the drill rod. The bottom end of the limiting guide rail is fixedly connected to the base plate, and the side of the limiting guide rail is fixedly connected to the adjacent main plate. The fastener is located between the two limiting guide rails.

[0019] The inclined sliding plate is slidably disposed between the guide plate and the limit guide rail.

[0022] The gear set is housed inside the housing, and a water inlet is located on the top of the housing. The water inlet includes a water inlet pipe and a water inlet pipe support frame.

[0023] The slide plate and the box body are fixed on the slide plate. The slide plate is fixedly connected to the lifting hydraulic cylinder, and the slide plate is slidably connected to the drilling tower.

[0024] The tower-raising mechanism includes:

[0025] The tower-raising hydraulic cylinder connects the drilling tower and the frame. The cylinder body of the tower-raising hydraulic cylinder is rotatably connected to the frame, and the piston rod of the tower-raising hydraulic cylinder is rotatably connected to the support plate located on the rear side of the drilling tower.

[0035] The rope has one end wound around the winch and the other end connected to the core sleeve set inside the drill pipe. The rope is wound around the guide wheel and the top wheel in sequence.

[0036] The beneficial effects of this utility model are:

[0037] (1) The machine can move by means of tracks. When the machine moves to the designated position, the telescopic hydraulic cylinders in the front and rear outriggers can keep the machine body in a horizontal state to adapt to different working terrains. In addition, the telescopic hydraulic cylinders can also lift the whole machine to a certain height to facilitate loading and transportation of the whole machine.

[0038] (2) The rotation of the drill rod and the continuous feed of the drill rod are realized through the rotary mechanism. During the rotation and continuous feed of the drill rod, the drill bit is continuously drilled into the geological layer and continuously breaks the rock. In conjunction with the rope mechanism, engine, oil pump, generator, battery, hydraulic oil tank and control box, automatic drilling of deep geological or hard mineral areas is realized.

[0039] (3) During the process of drilling and lifting the core, the clamping mechanism is in a loose state on the drill rod, and the rotary mechanism drives the drill rod to rotate, thus realizing the drilling of the core; during the process of installing and removing the drill rod, the clamping mechanism clamps the drill rod and fixes the position of the drill rod, thus enabling the installation and removal of the drill rod.

[0040] (4) The angle adjustment of the drilling tower and drill rod is realized by the tower lifting hydraulic cylinder, thus realizing multi-angle operation of rock core; in addition, when the angle of the drill rod is adjusted, the distance between the drilling tower and the ground changes. At this time, the base mechanism at the bottom of the drilling tower is always in contact with the ground by the tower compensation hydraulic cylinder, ensuring that the bottom of the drilling tower is always supported on the ground, ensuring the stability of the whole machine during the drilling process, and ensuring the drilling quality and effect.

[0041] (5) In addition, the drilling tower can be rotated by the tower lifting hydraulic cylinder. When the drilling tower is not in operation, it can be rotated to the horizontal direction. At the same time, the connection between the upper mast and the lower mast is changed, and the upper mast is rotated to the side of the lower mast, which realizes the folding of the mast. This facilitates the movement and transportation of the drilling rig. Attached Figure Description

[0056] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0057] Specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0058] like Figures 1 to 2 As shown, the self-propelled fully hydraulic wireline core drill of this invention includes a frame 4, with two tracks 5 at the bottom of the frame 4, enabling the drill to move during operation. Front outriggers 14 are located on the left and right sides of the front end of the frame 4, and rear outriggers 8 are located on the left and right sides of the rear end of the frame 4. Telescopic hydraulic cylinders are installed inside the front outriggers 14 and rear outriggers 8, allowing control of the height of each outrigger. When the machine operates on uneven ground, the height of each outrigger is adjusted by the operation of the telescopic hydraulic cylinders, keeping the entire machine level to adapt to different terrains. Furthermore, the telescopic hydraulic cylinders can also lift the entire machine to a certain height, facilitating loading and transportation.

[0059] The front end of the frame is equipped with a vertically oriented drilling rig 13, which is connected to the frame via a rig-raising mechanism. The bottom of the drilling rig 13 has a base mechanism 75 for supporting it, and the top of the drilling rig 13 has a rope mechanism. A drill rod is connected to the lower end of the drilling rig 13. The top end of the drill rod is connected to a rotary mechanism 2, and a drill bit is fixed to the bottom end of the drill rod. As the rotary mechanism drives the drill rod to rotate, the drill bit continuously penetrates the geological strata and continuously breaks up the rock.

[0060] As the drill bit continues to penetrate the geological formation, the length of the drill pipe also needs to be continuously increased. Therefore, during continuous drilling, the number of drill pipe sections needs to be continuously increased, and new drill pipes need to be connected to the existing ones, thus continuously extending the length of the drill pipe. During drill pipe installation, a clamping mechanism is used to clamp and fix the drill pipe; however, during drilling, the clamping mechanism is in a released state. The drill pipe passes through the clamping mechanism 1, and the rotary mechanism 2 is located above the clamping mechanism 1, with the top of the drill pipe connected to the rotary mechanism 2. The clamping mechanism 1 is located above the base mechanism 75. Both the rotary mechanism 2 and the clamping mechanism 1 are mounted on the drill tower 13.

[0061] like Figures 3 to 7As shown, the clamping mechanism includes a base plate 28, two symmetrically arranged main body plates 46, and two symmetrically arranged clamping blocks. The base plate 28 is fixedly connected to the drill tower 13, and the main body plates 46 are fixed on the base plate 28, forming a cavity between the base plate 28 and the main body plates 46. The two clamping blocks are disposed within this cavity. When drilling is required, the drill rod is positioned between the two clamping blocks, with a gap between the drill rod and the clamping blocks to facilitate the rotation of the drill rod and the drilling action. As the drilling depth increases, multiple drill rod sections need to be installed successively. During the installation of the drill rod, the drill rod is clamped by the clamping blocks, and more drill rod sections are installed on the existing drill rod to enable the drill rod to drill deeper wells. The base plate 28 has a through hole through which the lower end of the drill rod passes.

[0062] The two clamping blocks move up and down synchronously, and the distance between them changes accordingly during this movement. When both clamping blocks reach their highest point, the distance between them is at its maximum, at which point they release the drill rod. When they reach their lowest point, the distance between them is at its minimum, thus clamping and fixing the drill rod located between them. In this embodiment, the up and down movement of the two clamping blocks can be achieved using a hydraulic cylinder.

[0063] The clamping block has a clamping arc-shaped side facing the drill pipe, and the side facing away from the drill pipe is fixedly connected to the sliding member. The two sliding members connected to the two clamping blocks are symmetrically arranged. The sliding member includes an inclined sliding plate and a hydraulic cylinder connecting plate fixed to the top of the inclined sliding plate. In this embodiment, the inclined sliding plate and the hydraulic cylinder connecting plate are vertically fixedly connected, so the sliding plate is an L-shaped plate. There is a certain angle between the inclined sliding plate and the vertical direction, and the top of the inclined sliding plate is inclined away from the drill pipe. Therefore, the distance between the tops of the two sliding members is greater than the distance between their bottoms.

[0064] The hydraulic cylinder connecting plates of the sliding component are connected to the hydraulic cylinders, which are also inclined. During the synchronous operation of the two hydraulic cylinders, the inclined sliding plates are driven to move up and down synchronously through the hydraulic cylinder connecting plates.

[0065] The top end of the piston rod of the hydraulic cylinder is connected to the hydraulic cylinder connecting plate. In this embodiment, the top end of the hydraulic cylinder piston rod passes through the hydraulic cylinder connecting plate and is located above the hydraulic cylinder connecting plate. The top end of the hydraulic cylinder piston rod is provided with external threads, and is connected to the fastening nut 51 through threaded engagement. The fastening nut 51 can lock the hydraulic cylinder piston rod, enabling the hydraulic cylinder to drive the sliding component to move up and down.

[0066] A trunnion 76 is fixed to the cylinder body of the hydraulic cylinder, and a corresponding trunnion hole is provided on the main body plate, with the trunnion disposed within the trunnion hole. One end of the trunnion is fixedly connected to the cylinder body of the hydraulic cylinder; the other end of the trunnion is located on the outer side of the main body plate and is fixedly connected to a hydraulic cylinder limiting sleeve 37 located on the outer side of the main body plate. In this embodiment, the hydraulic cylinder limiting sleeve 37 and the trunnion 76 are in clearance fit, and the hydraulic cylinder limiting sleeve 37 is fixedly connected to the main body plate 46 by bolts. Therefore, the hydraulic cylinder limiting sleeve 37 achieves the connection between the hydraulic cylinder and the main body plate 46, and serves to limit the movement of the hydraulic cylinder.

[0067] In this embodiment, each hydraulic cylinder has two trunnions 76 symmetrically arranged on its cylinder body, and hydraulic cylinder limiting sleeves 37 are respectively provided on the outer side of the main body plate on both sides. Therefore, the connection between the hydraulic cylinder and the main body plate 46 is realized by the four hydraulic cylinder limiting sleeves 37 connected to the hydraulic cylinders on both sides respectively.

[0068] The clamping blocks are fixedly connected to the inclined sliding plate by fasteners. The side of the clamping block facing the drill rod has a clamping arc surface, which directly contacts the outer surface of the drill rod, thus clamping and fixing the drill rod through the clamping blocks on both sides. The side of the clamping block away from the drill rod is fixedly connected to the inclined sliding plate by fasteners. The side where the fastener is fixed to the clamping block is a vertical surface, while the side where the fastener is fixed to the inclined sliding plate is an inclined surface. Therefore, as the hydraulic cylinder drives the sliding component to move up and down, and simultaneously drives the two clamping blocks to move up and down, the distance between the two clamping blocks also changes accordingly. When the piston rod of the hydraulic cylinder extends and drives the sliding component upward, the two clamping blocks move upward and also move away from the drill rod, thus increasing the distance between the two clamping blocks and releasing the drill rod; when the piston rod of the hydraulic cylinder retracts and drives the sliding component downward, the two clamping blocks move downward and also move towards the drill rod, thus decreasing the distance between the two clamping blocks and gradually achieving clamping and fixing of the drill rod.

[0069] To ensure the sliding component can move up and down normally, a guide plate 32 is provided on the outer side of the inclined sliding plate away from the drill pipe. The bottom of the guide plate 32 is fixedly connected to the base plate 28, and the sides of the guide plate 32 are fixedly connected to the main body plates on both sides. The guide plate 32 is also inclined, and its inclination angle is the same as that of the inclined sliding plate. The guide plate 32 is located on the side of the inclined sliding plate facing the drill pipe, and the inclined sliding plate and the guide plate 32 can slide relative to each other. Therefore, during the up and down movement of the sliding component, the guide plate 32 guides the up and down sliding of the inclined sliding plate.

[0070] Two parallel limiting guide rails 27 are provided on the side of the inclined sliding plate facing the drill pipe. The bottom end of the limiting guide rail 27 is fixedly connected to the base plate 28, and the limiting guide rail 27 is also fixedly connected to its adjacent main body plate. The limiting guide rail 27 is also inclined, and its inclination angle is the same as that of the inclined sliding plate. The inclined sliding plate and the limiting guide rail 27 slide relative to each other. Therefore, the sliding element is slidably disposed between the guide plate 32 and the limiting guide rail 27, and the guide plate 32 and the limiting guide rail 27 guide the sliding of the sliding element. At the same time, the fastener is located between the two limiting guide rails 27, and the limiting guide rails guide the fastener as it moves with the sliding element.

[0071] To ensure synchronized movement of the sliding members on both sides, the tops of the sliding members are connected by pairs of balance bars. In this embodiment, the tops of the sliding members on both sides are connected by two pairs of balance bars. Figure 7 As shown, the paired balance bars include a first balance bar 351 and a second balance bar 352. The first balance bar 351 and the second balance bar 352 are fixedly connected to the sliding members on both sides, and the two balance bars are slidably connected by an insertion method.

[0072] One end of the first balance bar 351 is fixedly connected to a sliding member on one side by welding, and its end facing the second balance bar has an elongated slot. One end of the second balance bar 352 is fixedly connected to a sliding member on the other side by welding, and its end facing the first balance bar has an elongated protrusion, which is slidably disposed within the elongated slot.

[0073] During the extension or retraction of the hydraulic cylinder piston rod, the first and second balance bars rise or fall simultaneously with the sliding parts on both sides. At the same time, when the distance between the two sliding parts changes, the elongated protrusion slides accordingly within the elongated slot. Through the relative sliding between the first and second balance bars, the synchronized up-and-down movements of the sliding parts on both sides are effectively ensured, thereby further achieving the purpose of loosening and clamping the drill rod.

[0074] A drill pipe stabilizer 31 is also provided between the sliding parts on both sides. The drill pipe passes through the drill pipe stabilizer 31, which is used to restrain and correct the drill pipe deviation. A deep groove ball bearing is installed inside the drill pipe stabilizer 31 to reduce friction with the drill pipe. The drill pipe stabilizer 31 is fixedly mounted on the stabilizer base plate 49. The stabilizer base plate 49 is fixedly connected to the lower stabilizer fixing plate 50 below it by bolts. The lower stabilizer fixing plate 50 is fixedly connected to the main body plates 46 on both sides by welding.

[0075] In this embodiment, two symmetrically arranged sliding members are a first sliding member 25 and a second sliding member 34. The first sliding member 25 is connected to a first hydraulic cylinder 26, and the second sliding member 34 is connected to a second hydraulic cylinder 33. During the up-and-down sliding process, the first sliding member 25 and the second sliding member 34 slide between the guide plate 32 and the limiting guide rail 27, respectively, thereby guiding the first sliding member and the second sliding member. The first sliding member 25 is fixedly connected to the first clamping block 29 by a first fastener 36, and the second sliding member 34 is fixedly connected to the second clamping block 30 by a second fastener 77. The drill rod is located between the first clamping block 29 and the second clamping block 30. During the up-and-down sliding process of the first sliding member 25, the first clamping block 29 is driven to slide up and down by the first fastener 36; during the up-and-down sliding process of the second sliding member 34, the second clamping block 30 is driven to slide up and down by the second fastener 77.

[0076] like Figure 8 As shown, the rotary mechanism includes a slide plate 39, a rotary motor 41, and a housing 42. The rotary motor 41 is mounted on the housing 42, and a gear set is installed inside the housing. The output shaft of the rotary motor 41 is rotatably connected to a power output shaft 44 via the gear set, and the power output shaft 44 is connected to the drill rod. Therefore, during the rotation of the rotary motor 41, power is transmitted to the power output shaft 44 through the gear set, driving the drill rod to rotate.

[0077] The rotary motor 41 has a liquid inlet 40 at its top. Hydraulic oil enters the rotary motor 41 through the liquid inlet 40, driving the rotary motor 41 to operate. The housing 42 has a water inlet 45, which includes a water inlet pipe and a water inlet pipe support frame, the latter fixed to the housing 42. Water is injected into the drill rod through the water inlet 45 to cool the drill rod and drill bit during operation. The top surface of the housing 42 also has a lubrication cup 43, through which lubricating oil is injected into the gear set to lubricate it.

[0078] The housing 42 is fixedly connected to the slide plate 39 by bolts. The slide plate 39 is fixedly connected to the lifting hydraulic cylinder 21. During the operation of the lifting hydraulic cylinder 21, the slide plate 39 and the housing 42 move up and down, thereby driving the drill rod to rise and fall. During the downward movement of the housing 42, the drill rod moves downward; at the same time, the rotary motor 41 drives the drill rod to rotate, thereby realizing the drilling of the core. To ensure that the housing 42 can move up and down smoothly along the drilling tower, a vertical first slider 38 is fixed to the rear side of the slide plate 39. The first slider 38 has a first groove. A rotary mechanism lifting guide rail 80 is fixed to the side of the drilling tower along the height direction. The rotary mechanism lifting guide rail 80 is slidably set in the first groove, thereby realizing the sliding connection between the rotary mechanism and the drilling tower. Therefore, during the operation of the lifting hydraulic cylinder 21, the slide plate 39 moves up and down along the drilling tower through the first slider 38, thereby guiding the vertical movement of the drill rod and realizing the lifting and falling of the drill rod.

[0079] In this embodiment, the bottom of the piston rod of the lifting hydraulic cylinder 21 is rotatably connected to the drilling tower, and the cylinder body of the lifting hydraulic cylinder 21 is fixedly connected to the slide plate 39 through the lifting cylinder connecting plate 65. Therefore, during the operation of the lifting hydraulic cylinder 21, the cylinder body of the lifting hydraulic cylinder 21 can drive the rotary mechanism to achieve up and down lifting.

[0080] The top of the drill pipe is equipped with a rope mechanism, which includes a winch 3 and a mast 12. The winch 3 is mounted on the frame 4. The bottom of the mast 12 is fixedly connected to the top surface of the drill tower 13, and the top of the mast 12 is equipped with a sheave 11, which is mounted on the top of the mast 12 via a sheave bracket 59. A guide pulley 22 is located in the middle of the mast 12. One end of the rope is wound around the winch 3, and the other end of the rope is fixedly connected to the core sleeve located inside the drill pipe. The middle part of the rope is wound sequentially around the guide pulley 22 and the sheave 11, which plays a guiding role in the movement of the rope.

[0081] During the drilling process, as the drill rod moves downwards, winch 3 releases the rope, and the core sleeve connected to the rope also moves downwards with the drill rod. The rock core drilled by the drill rod directly enters the core sleeve. When core extraction is needed, winch 3 retracts the rope, and the rope drives the core sleeve upwards, thus completing the core extraction operation.

[0082] The length of mast 12 is adjustable. Mast 12 includes an upper mast 121 and a lower mast 122. The bottom end of the lower mast 122 is fixedly connected to the top of the rig 13, and a lower mast welding plate 57 is fixed to the top of the lower mast 122. An upper mast welding plate 56 is fixed to the bottom of the upper mast 121, and a sheave 11 is fixed to the top of the upper mast. The upper mast welding plate 56 and the lower mast welding plate 57 are rotatably connected by a cylindrical hinge 58.

[0083] During the operation of the drilling rig, the upper mast welding plate 56 is located above the lower mast welding plate 57, and the upper mast welding plate 56 and the lower mast welding plate 57 are fixedly connected by bolts. At this time, the upper mast 121 is located above the lower mast 122.

[0084] When the drilling rig is not in operation and is in the traveling state, remove the connecting bolts between the upper mast welding plate 56 and the lower mast welding plate 57. The upper mast welding plate 56 rotates around the cylindrical hinge 58, causing the upper mast 121 to rotate to the side of the lower mast 122, thereby shortening the overall height of the machine.

[0085] like Figures 9 to 13 As shown, the drilling rig 13 and the frame 4 are connected by a rig lifting mechanism. The rig lifting mechanism includes a rig lifting hydraulic cylinder 19 and a rig compensation hydraulic cylinder 20. The cylinder body of the rig lifting hydraulic cylinder 19 is rotatably connected to the frame 4, and the piston rod of the rig lifting hydraulic cylinder 19 is rotatably connected to a support plate 47 located on the rear side of the drilling rig 13. The support plate 47 and the drilling rig 13 are slidably connected. In this embodiment, a second vertical slider is fixed to the front side of the support plate 47, and a second sliding groove is provided in the second slider. A rig lifting guide rail 81 is provided on the side of the drilling rig along the height direction. The rig lifting guide rail 81 is slidably arranged in the second sliding groove, thereby realizing the sliding connection between the support plate 47 and the drilling rig. The support plate 47 and the front end of the frame 4 are rotatably connected.

[0086] In this embodiment, the top end of the piston rod of the tower-lifting hydraulic cylinder 19 is rotatably connected to the third fixed lug 72 fixed on the support plate 47 via the third rotating shaft 73, and the bottom end of the cylinder body of the tower-lifting hydraulic cylinder 19 is rotatably connected to the fourth fixed lug 74 fixed on the frame 4 via the fourth rotating shaft 78.

[0087] A hydraulic oil tank 18 is fixed to the front end of the frame 4, and two first drill tower supports 23 are fixed to the rear side of the support plate 47. The two first drill tower supports 23 are connected by a connecting shaft. At the same time, both ends of the connecting shaft are rotatably connected to the fixed seats 79 fixed on the hydraulic oil tank 18. During the operation of the tower-raising hydraulic cylinder 19, the tower-raising hydraulic cylinder 19 pulls the support plate 47 and the connecting shaft to rotate around the rotatable connection between the connecting shaft and the fixed seat 79, thereby causing the support plate 47 to drive the drill tower 13 to rotate. The rotation angle of the drill tower 13 is determined by the extension and retraction length of the piston rod of the tower-raising hydraulic cylinder 19. By rotating the drill tower, the drilling angle of the drill rod can be adjusted, multi-angle operation of the drill rod can be realized, and the entire machine can be folded up and stored when not in use.

[0088] A second drilling rig support 24 is also fixed on the frame. When the machine does not need to drill rock cores, the drilling rig 13 rotates to the horizontal direction. At this time, the second drilling rig support 24 provides support for the horizontal drilling rig 13, which facilitates the transportation of the machine.

[0089] This application also allows for the adjustment of the turret height via the turret compensation hydraulic cylinder 20. When the turret angle changes, the distance between the turret and the ground changes, i.e., the distance between the drill rod and the ground changes. At this time, the piston rod of the turret compensation hydraulic cylinder 20 can drive the turret 13 to move up and down, ensuring that the bottom of the turret is always supported on the ground, thus ensuring the stability of the entire machine during drilling and guaranteeing drilling quality and effectiveness.

[0090] The bottom of the cylinder body of the drilling tower compensation hydraulic cylinder 20 is rotatably connected to the support plate 47, the top of the piston rod of the drilling tower compensation hydraulic cylinder 20 is rotatably connected to the drilling tower connecting plate 60, and the drilling tower connecting plate 60 is fixedly connected to the upper part of the back of the drilling tower.

[0091] In this embodiment, the bottom of the cylinder body of the drilling rig compensation hydraulic cylinder 20 is rotatably connected to the second fixing lug 70 fixed on the support plate 47 via a second rotating shaft 71. The top end of the piston rod of the drilling rig compensation hydraulic cylinder 20 is rotatably connected to the first fixing lug 68 fixed on the drilling rig connecting plate 60 via a first rotating shaft 69.

[0092] like Figure 9 As shown, the base mechanism includes a turret base plate 53, on which two base uprights 54 are fixed. The base uprights 54 are located on two symmetrical outer sides of the bottom of the turret, and are rotatably connected to the bottom of the turret via base pivots 55. The bottom surface of the turret base plate 53 is provided with turret foot plates 52, which are corrugated. During drilling, the turret is supported on the ground by the base mechanism, and the turret foot plates 52 increase the friction between the turret and the ground.

[0093] The rear of the frame 4 houses an engine 9 and an oil pump 10. These provide power to the tracks 5, enabling the drilling rig to move forward and backward. Simultaneously, the engine 9 drives the oil pump, which, through hydraulic valves in the control box, controls the hydraulic transmission, driving the rotary motor 41 to provide torque for the drill rod's rotation, allowing the drill bit to continuously break rocks. The frame 4 also includes a mud pump 6, which injects mud into the drill rod to dissipate the heat generated by the drill bit during rock breaking, preventing wear or damage due to high temperatures. The mud pump 6 also removes rock dust, protects the borehole wall, and drives the drilling tools.

[0094] The frame 4 is also equipped with a generator 7 and a battery 16. The electrical energy stored in the battery 16 is used to provide power for the entire machine operation. The generator 7 is mainly used for field construction, such as welding.

[0095] The frame 4 also includes a water-cooled radiator 48 and an operating box 17. The water-cooled radiator 48 cools the hydraulic oil in the entire hydraulic system, preventing overheating from affecting normal operation. The operating box 17 contains a multi-way valve for distributing power, controlling the drill's movement, and adjusting the drill rod's direction and speed, enabling the drill rod to rise, fall, and stop. The operating box 17 also contains multiple hydraulic control valves that control the corresponding actions of the hydraulic cylinders in the drill.

[0096] The machine described in this application is mainly used for various geological exploration and mining research operations to extract columnar rock cores from drill holes for geological and mineral research. The working principle of the machine is as follows: First, the engine 9 and oil pump 10 drive the tracks 5, propelling the entire machine to the exploration area. Upon arrival at the exploration area, the front outriggers 14 and rear outriggers 8 adjust the machine's level, ensuring the machine body is in a horizontal position.

[0097] During drilling, the drill rod is rotated by the rotary motor 15, enabling the drill bit to continuously break the rock. Simultaneously, the lifting hydraulic cylinder 21 actuates, moving the drill rod up and down to adjust and maintain the axial load at the drill bit, and feeding the drill string according to the drill bit's drilling speed, ensuring continuous drilling. During drilling, the obtained rock core is placed inside the core sleeve. The core sleeve and the rock core inside are then removed using the winch 3.

[0098] During the drilling process, the angles of the drill tower and drill rod can be adjusted using the tower-lifting hydraulic cylinder 19. When the drill tower tilts, the distance between the drill tower and the ground will change accordingly. At this time, the drill tower compensation cylinder 20 can be used to ensure that the bottom of the drill tower is always in contact with the ground, thus ensuring the stability of the drilling rig during the drilling process.
