Description

Technical Field

[0001] This invention relates to the field of underground roadway drilling technology in coal mines, specifically to an integrated tunneling and anchoring machine with advanced drilling capabilities and a coal mine tunneling and mining system. Background Technology

[0002] In coal mining, advanced drilling rigs are mounted on the cutting arm of a roadheader. The pitch angle of the advanced drilling rig is adjusted by the up-and-down swing of the cutting arm to meet drilling requirements at different positions and angles. However, the cutting arm is used for tunnel excavation, and its swing angle range is limited by its mechanical structure and performance. This results in significant blind spots when adjusting the pitch angle, preventing the advanced drilling rig from reaching suitable drilling angles in certain areas of the working face, thus hindering effective and accurate drilling of the advanced area. Summary of the Invention

[0003] This invention is based on the inventor's discoveries and understanding of the following facts and problems: In coal mine excavation operations, advance drilling can obtain geological information ahead, detect geological hazards such as faults and aquifers in advance, and provide a reliable basis for the formulation of tunneling plans. In related technologies, an advance drilling rig is installed on the cutting arm of a roadheader-anchor machine. The pitch angle of the advance drilling rig is adjusted by swinging the cutting arm up and down, thus meeting the drilling needs at different positions and angles, and achieving advance drilling functionality to a certain extent.

[0004] However, the primary function of the cutting arm is tunnel excavation, and its swing angle range is limited by its mechanical structure and performance. This results in significant dead zones when adjusting the pitch angle of the advance drilling rig. In some areas of the tunneling face, the advance drilling rig cannot be adjusted to a suitable drilling angle, making it difficult to conduct comprehensive and accurate drilling of the advance area. This not only makes it difficult to detect potential geological hazards in a timely manner, increasing safety uncertainties in the production process, but also may affect the rational formulation of tunneling plans due to inaccurate drilling information, thereby reducing coal mining efficiency.

[0005] Therefore, embodiments of the present invention propose an integrated tunneling and anchoring machine and a coal mine tunneling system with advanced drilling capabilities, which can reduce blind spots in detection, ensure the accuracy of detection, and achieve effective detection of advanced areas.

[0006] The present invention provides a roadheader-anchor integrated machine with advanced drilling capabilities, comprising a cutting arm and an advanced drilling device, wherein the advanced drilling device includes: A sliding assembly, comprising a mounting base and a sliding seat, wherein the mounting base is disposed on the cutting arm and the sliding seat is slidably disposed on the mounting base; A pitch adjustment assembly includes an adjustment base and a pitch driver.

[0024] 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.

[0025] like Figures 1 to 6 As shown, one embodiment of the present invention provides a tunneling and anchoring integrated machine with advanced drilling capability, which includes a cutting arm 1 and an advanced drilling device 2. The advanced drilling device 2 includes a sliding assembly 10, a pitch adjustment assembly 20, a left-right swing assembly 30, and a drilling assembly 40. The sliding assembly 10 includes a mounting base 11 and a sliding seat 12. The mounting base 11 is disposed on the cutting arm 1, and the sliding seat 12 is slidably disposed on the mounting base 11. The pitch adjustment assembly 20 includes an adjustment seat 21 and a pitch driver 22. The adjustment seat 21 is rotatably connected to the sliding seat 12, and the pitch driver 22 is disposed on the sliding seat 12. The output end of the pitch driver 22 is drively connected to the adjustment seat 21 to drive the adjustment seat 21 to rotate relative to the sliding seat 12.

[0026] The left-right swing assembly 30 includes a swing base 31 and a swing driver 32. The swing base 31 is rotatably connected to the adjusting base 21, and the rotation axis of the swing base 31 is perpendicular to the rotation axis of the adjusting base 21. The swing driver 32 is located on the adjusting base 21, and its output end is connected to the swing base 31 to drive the swing base 31 to rotate relative to the adjusting base. The drilling assembly 40 is located on the swing base 31 and is used to form a pre-exploration hole in the area to be drilled.

[0027] Specifically, the advanced drilling device 2, through the coordinated operation of the sliding assembly 10, the pitch adjustment assembly 20, the left and right swing assembly 30, and the drilling assembly 40, can effectively detect the advanced area, ensuring flexibility and accuracy during the drilling process. The sliding assembly 10, fixed to the cutting arm 1 by the mounting base 11, provides a stable platform for the entire drilling device, allowing the advanced drilling device 2 to move synchronously with the cutting arm 1. The sliding seat 12 can slide relative to the mounting base 11, and can be adjusted in a specific direction (e.g., towards or away from the working face, towards or away from the roadway sidewall), providing the necessary displacement freedom for subsequent drilling operations.

[0028] The pitch adjustment component 20 can adjust the vertical tilt angle of the drilling component 40 via the adjustment seat 21 to adapt to areas where the cutting arm 1 cannot swing to its designated position, thus expanding and improving the detection range of the advanced drilling device 2 and reducing blind spots. In actual operation, when geological conditions are complex or the working space is limited, the pitch adjustment component 20 can adjust the vertical tilt angle of the drilling component 40, making the drilling direction more flexible and diverse, thereby reducing blind spots. For example, when encountering inclined strata or needing to detect geological conditions at specific locations above or below, the pitch adjustment component 20 can quickly adjust the drilling angle to ensure the comprehensiveness and accuracy of the drilling operation.

[0029] The left-right swing component 30 allows for horizontal adjustment of the advanced drilling device 2, thereby covering a wider drilling area. For example, when it is necessary to explore the geological conditions of a large area on both sides or in front of the tunnel, the left-right swing component 30 can quickly adjust the drilling direction, enabling the drilling component 40 to form advanced probe holes at different locations, thus providing a comprehensive understanding of the geological conditions of the work area. The drilling component 40 can accurately form advanced probe holes in the area to be drilled according to preset parameters and instructions, effectively preventing potential safety hazards caused by unknown geological conditions and ensuring the safety and efficiency of construction.

[0030] In summary, the advanced drilling integrated drilling and anchoring machine provided by the present invention, through the coordinated work of the sliding component 10, the pitch adjustment component 20, the left and right swing component 30 and the drilling component 40, can reduce the occurrence of blind spots in the detection, ensure the accuracy of the detection, and achieve effective detection of the advanced area.

[0031] In this embodiment, the sliding assembly 10 further includes a transmission screw 13. The mounting base 11 is provided with a receiving cavity 111. The transmission screw 13 is rotatably disposed in the receiving cavity 111. The transmission screw 13 is threadedly connected to the sliding seat 12 to drive the sliding seat 12 to move relative to the mounting base 11, thereby realizing precise control of the movement of the sliding seat 12 relative to the mounting base 11 and improving the performance and reliability of the equipment.

[0032] Furthermore, the sliding assembly 10 also includes a sliding driver 14, the output end of which is connected to the transmission screw 13 to drive the transmission screw 13 to rotate.

[0033] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the pitch adjustment assembly further includes a linkage crank 23 and a connecting shaft 24 connected to each other. The linkage crank 23 has a first end 231 and a second end 232 that are disposed opposite to each other. The connecting shaft 24 is located between the first end 231 and the second end 232. The connecting shaft 24 is rotatably connected to the sliding seat 12. The first end 231 is connected to the output end of the pitch driver 22, and the second end 232 is connected to the adjustment seat 21.

[0034] Specifically, the linkage crank 23 is curved, and its curvature and length are designed to maximize mechanical transmission efficiency and range of motion within the effective space, allowing for sufficiently large displacement and angular changes. When the pitch actuator 22 is activated, it generates a force that is transmitted to the linkage crank 23 via the first end 231, and then to the adjusting seat 21 via the second end 232, thus converting it into rotational motion of the adjusting seat 21 and adjusting the pitch angle of the drilling assembly 40. The connecting shaft 24 is located between the first end 231 and the second end 232 of the linkage crank 23, ensuring that the linkage crank 23 can rotate flexibly around its own axis. Simultaneously, the lever principle effectively amplifies the force received at the first end 231. For example, the distance from the first end 231 to the connecting shaft 24 is greater than the distance from the connecting shaft 24 to the second end 232.

[0035] Furthermore, the pitch actuator 22 includes a threaded screw 221 and a movable seat 222. The movable seat 222 is threadedly connected to the threaded screw 221. The movable seat 222 is provided with a first sliding groove 224. The first end 231 of the linkage crank 23 is provided with a first sliding post 233 that cooperates with the first sliding groove 224. The adjusting seat 21 is provided with a second sliding post 211. The second end 232 of the linkage crank 23 is provided with a second sliding groove 234 that cooperates with the second sliding post 211.

[0036] In this embodiment, the pitch driver 22 also includes a drive element 223, such as a motor, hydraulic motor, etc. The drive element 223 is connected to the threaded screw 221. The threaded screw 221 can extend along the vertical direction of the mounting base 11. The movable base 222 is installed on the threaded screw 221 through a threaded connection. It can move precisely in a straight line under the drive of the threaded screw 221, ensuring that the movable base 222 can only move in a straight line along the axis of the screw, thus avoiding angle adjustment errors caused by offset or shaking.

[0037] When it is necessary to adjust the pitch angle of the drilling assembly 40, the drive element 223 can drive the threaded screw 221 to rotate, causing the moving seat 222 to move linearly along the axis of the threaded screw 221. The first sliding column 233 on the moving seat 222 slides in the first sliding groove 224, pushing the first end 231 of the linkage crank 23 to swing. The linkage crank 23 rotates around the connecting shaft 24, and the second sliding groove 234 at the second end 232 of the linkage crank 23 drives the second sliding column 211 on the adjusting seat 21 to slide, causing the adjusting seat 21 to rotate, and finally realizing the pitch angle adjustment of the drilling assembly 40.

[0038] Furthermore, the second slide groove 234 extends along the length of the linkage crank 23, and the sliding seat 12 is provided with a third slide groove. The third slide groove extends around the rotation axis of the adjusting seat 21, and the second slide column 211 slides in the third slide groove, thereby limiting the pitch angle adjustment range of the adjusting seat 21. That is, the maximum adjustment angle of the adjusting seat 21 is limited by the extreme positions of the two ends of the third slide groove.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments, the drilling assembly 40 includes a screw drive 41, a chuck 42, and a guide 43. The screw drive 41 is disposed on the swing seat 31. The output end of the screw drive 41 is connected to the chuck 42 to drive the chuck 42 to rotate. The chuck 42 is used to fix the drill rod. The guide 43 is coaxially arranged with the chuck 42 and has a through cavity 431 for the drill rod to pass through.

[0040] Specifically, the rotary actuator 41 is the power source of the drilling assembly 40. It is fixedly mounted on the swing seat 31. Through the cooperation of the swing seat 31 and the adjusting seat 21, a stable and flexibly adjustable working platform is provided for the rotary actuator 41, allowing it to precisely adjust the drilling direction of the drill rod according to different drilling needs and geological conditions. The chuck 42 is an important component in the drilling assembly 40 used to fix the drill rod. It is closely connected to the output end of the rotary actuator 41. When the rotary actuator 41 starts and drives the chuck 42 to rotate, the chuck 42 can tightly clamp the drill rod, making it rotate synchronously with the chuck 42, thereby realizing the drilling action of the drill rod.

[0041] The guide 43, coaxially arranged with the chuck 42, is a key component in the drilling assembly 40 that ensures accurate drilling of the drill rod. It has a through cavity 431 through which the drill rod passes. The size and shape of the through cavity 431 are precisely designed to fit tightly with the outer diameter of the drill rod, providing a stable and precise guiding channel for the drill rod.

[0042] When drilling begins, the rotary actuator 41 starts, and its output drives the chuck 42 to rotate. The chuck 42 tightly clamps the drill rod, causing it to rotate together with the drill rod. Simultaneously, the drill rod passes through the through cavity 431 of the guide 43 and, under the precise guidance of the guide 43, drills deeper into the formation along a predetermined direction. During drilling, the rotary actuator 41 adjusts the rotation speed and torque of the drill rod in real time according to the hardness of the formation and the drilling progress; the chuck 42 maintains a stable clamping force to ensure that the drill rod does not loosen or slip; and the guide 43 continuously provides precise guidance for the drill rod, ensuring the quality and accuracy of the borehole.

[0043] Furthermore, the chuck 42 includes a fixed cylinder 421 and multiple jaws. The fixed cylinder 421 is provided with a clamping cavity 422, and the jaws are located in the clamping cavity 422. The multiple jaws are movable relative to the fixed cylinder 421 in the radial direction to clamp the drill pipe.

[0044] The fixed cylinder 421 is cylindrical in shape, with a clamping cavity 422 inside. The size and shape of the clamping cavity 422 match the outer diameter of the drill pipe, providing a suitable space for the drill pipe. The jaws are the core component of the chuck 42, enabling it to clamp the drill pipe. Multiple jaws are evenly arranged within the clamping cavity 422 of the fixed cylinder 421. The number of jaws is typically determined by the design specifications and clamping requirements of the chuck 42, generally ranging from 3 to 6, to ensure uniform and stable clamping of the drill pipe from multiple directions. The chuck 42 can be hydraulically driven, with a hydraulic chamber and piston located within the fixed cylinder 421.

[0045] When the hydraulic system is started, high-pressure hydraulic oil enters the hydraulic chamber, pushing the piston to move. The piston is connected to the chuck, and the linear motion of the piston drives the chuck to move radially. Hydraulic drive has advantages such as large clamping force, smooth operation, and fast response. It can precisely control the movement distance and clamping force of the chuck according to the diameter of the drill pipe and drilling requirements, ensuring that the drill pipe is firmly clamped. Simultaneously, the hydraulic system can also achieve stepless adjustment of the clamping force by adjusting the pressure of the hydraulic oil, adapting to drill pipes of different specifications and materials.

[0046] Furthermore, the guide 43 includes a movable actuator 432 and two semi-rings 433. The two semi-rings 433 are arranged opposite each other, defining a through cavity. The movable actuator 432 is located on the swing seat 31, and its output end is connected to one of the two semi-rings 433 to drive the semi-ring 433 to move and open or close the through cavity. The two semi-rings 433 are arranged opposite each other, and when they are in the closed state, they form a complete through cavity. The center of the through cavity coincides with the central axis of the drill rod, providing a precise guiding reference for the drill rod. During drilling, the drill rod passes through the through cavity, and the inner surface of the semi-rings 433 is in close contact with the outer surface of the drill rod. Through friction and guiding action, the radial movement of the drill rod is restricted, ensuring that the drill rod always drills in the predetermined direction. At the same time, the through cavity can also prevent the drill rod from swinging during rotation, improving the straightness and accuracy of the borehole.

[0047] When drill pipe installation or replacement is required, the moving drive 432 is activated, causing the connected half-ring 433 to move away from the other half-ring 433, thus widening the opening of the through cavity. At this time, the drill pipe can be inserted into or removed from the through cavity. Then, the moving drive 432 is controlled in reverse, causing the connected half-ring 433 to move closer to the other half-ring 433 until the two half-rings 433 are tightly fitted together, closing the through cavity and firmly fixing the drill pipe inside.

[0048] In this embodiment, the guide 43 also includes a plurality of guide wheels, which are disposed within the semi-ring 433 to reduce the wear of the drill pipe by the guide 43 and extend the service life of the drill pipe.

[0049] It should be noted that in this embodiment, there are two moving drivers, and the two moving drivers are set one-to-one with the half rings, so that the two half rings can be operated simultaneously to realize the opening and closing of the through cavity.

[0050] like Figure 2 and Figure 3As shown, in some embodiments, the drilling assembly 40 further includes a receiving seat 44, which is disposed on the swing seat 31 and located on the side of the chuck 42 away from the guide 43. A rotating ring 441 is rotatably mounted on the receiving seat 44, and a placement groove 442 is provided on the rotating ring 441 for placing the drill rod. The receiving seat 44 can be fixed to the swing seat 31 by bolts or welding, and the rotating ring 441 can be connected to the receiving seat 44 by a bearing or bushing to achieve rotation. The shape and size of the placement groove 442 match the shape of the drill rod and can be semi-circular or V-shaped. The semi-circular placement groove 442 can fit tightly against the outer surface of the drill rod, providing a larger contact area, increasing friction, and preventing the drill rod from sliding or rolling during placement. The V-shaped placement groove 442 has a self-centering feature, which can accurately position the drill rod at the center of the placement groove 442, improving placement accuracy.

[0051] like Figure 2 and Figure 3 As shown, in some embodiments, the drilling assembly 40 further includes a feed driver 45, a chuck 42 slidably connected to a swing seat 31, the feed driver 45 is disposed on the swing seat 31, and the output end of the feed driver 45 is connected to the chuck 42 to drive the chuck 42 to move relative to the swing seat 31.

[0052] In this embodiment, the swing seat 31 is provided with a guide rail 33, and the chuck 42 is provided with a slider 423 that matches the guide rail 33. The fit gap between the slider 423 and the guide rail 33 can ensure that the chuck 42 slides smoothly and avoids shaking and vibration caused by excessive gap, thereby ensuring the stability and accuracy of the movement of the chuck 42.

[0053] The output of the feed driver 45 can be directly or indirectly connected to the chuck 42. Direct connection means the output of the feed driver 45 is directly connected to the chuck 42, for example, by connecting the motor's output shaft to the chuck 42's drive shaft via a coupling. This connection method is simple in structure, has high transmission efficiency, and can minimize power loss during transmission. However, direct connection requires high precision in the machining and assembly of parts; any slight deviation can lead to accelerated wear at the connection points, affecting the equipment's service life.

[0054] Indirect connection connects the output of the feed driver 45 to the chuck 42 via an intermediate transmission component (such as a gear, chain, or belt). This connection method provides buffering and shock absorption, reducing impact and vibration during power transmission and protecting the feed driver 45 and chuck 42 from damage. Furthermore, indirect connection allows for different feed speeds and torque outputs of the chuck 42 by changing the transmission ratio of the intermediate transmission component, increasing the flexibility and adaptability of the equipment. For example, with gear transmission, the transmission ratio can be changed by replacing gears with different numbers of teeth; with chain transmission, the center distance of the sprockets can be adjusted to meet different installation requirements.
