Description

Technical Field

[0001] The present invention relates to the technical field of coal mine drilling rigs, and in particular to a coal mine drilling rig with a directional function. Background Art

[0002] Drilling is a crucial step in coal mining operations. Traditional coal mine drilling rigs often have some significant problems during use. The geological conditions underground in coal mines are complex and changeable. During drilling operations, accurately controlling the direction and angle of the drill hole is crucial for improving mining efficiency, ensuring construction safety, and ensuring the effective extraction of resources. However, most existing coal mine drill rigs lack effective directional functions, making it difficult to drill accurately along the preset trajectory. This leads to deviations in the drilling position, which not only affects subsequent mining work, but also may cause waste of resources and increase mining costs. At the same time, inaccurate drilling may damage the geological structure of the coal mine and increase safety hazards such as collapse. In addition, the operation of traditional coal mine drills requires high technical and experience requirements from the operator. The operator needs to rely on subjective judgment and manual adjustments to control the drilling direction, which is not only inefficient but also difficult to ensure the accuracy and stability of the drilling orientation.

[0056] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0057] Example 1

[0058] Reference Figure 1, which is the first embodiment of the present invention, proposes a coal mine drilling rig with a directional function, including a frame 1; a rotating shaft 160 is rotatably arranged on the frame 1; a supporting frame 170 is arranged on the rotating shaft 160, and the rotating shaft 160 is used to control the orientation angle of the supporting frame 170; a first rotating driving member 180 is arranged on the supporting frame 170, and the rotating axis of the first rotating driving member 180 is perpendicular to the rotating axis of the rotating shaft 160; a drilling frame 190 is arranged on the first rotating driving member 180, and the first rotating driving member 180 is used to control the drilling angle of the drilling frame 190.

[0059] In this embodiment, the rotating shaft 160 can control the orientation angle of the support frame 170, and the first rotating drive member 180 is a rotary cylinder that can control the drilling angle of the drilling frame 190. The two work together to achieve multi-dimensional and precise control of the drilling direction of the coal mine drill rig, effectively solving the problem that traditional drill rigs are difficult to drill accurately according to the preset trajectory, and improving the accuracy and precision of drilling. The precise directional function helps to reduce the deviation of the drilling position, ensure the smooth progress of subsequent mining work, and avoid the waste of resources and increased mining costs caused by drilling deviation. Through precise control of the drilling direction, it is possible to minimize damage to the geological structure of the coal mine, reduce safety hazards such as collapse, and improve the safety of coal mining. This automated directional control method reduces the dependence on the operator's skills and experience, reduces the uncertainty caused by relying on subjective judgment and manual adjustment, improves the accuracy and stability of drilling orientation, and also improves work efficiency.

[0060] Example 2

[0061] Reference Figure 2 and Figure 3 On the basis of Example 1, as a further technical solution, it also includes: the sliding seat 2 is slidably set on the drilling frame 190; the clamping seat 230 is set on the drilling frame 190, and the sliding seat 2 slides close to or away from the clamping seat 230; the thread cleaning member 3 is lifted and set on the drilling frame 190, and the thread cleaning member 3 is located between the clamping seat 230 and the sliding seat 2. The thread cleaning member 3 is used to clean the threads on the drill rod, and the thread cleaning member 3 is lifted and moved close to or away from the drill rod.

[0062] In the present embodiment, the thread cleaning member 3 is arranged on a track on one side of the vehicle frame for supporting the top support rod of the coal mine. The thread cleaning member 3 is arranged to be lifted and lowered, and can clean the threads on the drill rod when needed. When not in use, it is removed from the drill rod. The operation is flexible and can adapt to the needs of different working stages. Timely cleaning of the drill rod thread can remove debris and dirt on the thread, ensure the tightness and reliability of the threaded connection, and reduce connection failures caused by thread blockage or damage. The cleaned thread helps to improve the loading and unloading efficiency of the drill rod, reduce operational delays caused by thread problems, and improve the working efficiency of the coal mine drilling rig. Keeping the drill rod thread clean can extend the service life of the drill rod and reduce equipment maintenance costs. The position between the clamping seat 230 and the sliding seat 2 is reasonably set, does not affect the normal operation of other components, and is convenient for effectively cleaning the drill rod thread.

[0063] Reference Figures 10 to 12 As a further technical solution, the thread cleaning member 3 includes: a water jacket 310 having an accommodating chamber 320; a first cleaning rod 330 slidably arranged at one end of the water jacket 310, and after the first cleaning rod 330 slides, it enters or leaves the water jacket 310, and the first cleaning rod 330 has a flow space 340 connected to the accommodating chamber 320 and a water spray hole connected to the flow space 340, and the first cleaning rod 330 is used to clean the internal thread of the drill pipe.

[0064] In this embodiment, the combined design of the water jacket 310 and the first cleaning rod 330 makes the cleaning structure more compact, saves space, and is convenient for installation and maintenance. The first cleaning rod 330 is slidingly arranged and can flexibly enter or leave the water jacket 310 as needed, thereby achieving precise cleaning of the inner threads of the drill pipe and improving the controllability and pertinence of the cleaning. The design of the flow space 340 and the water spray hole allows for simultaneous water spraying and flushing during the cleaning process, which enhances the cleaning effect and can more effectively remove dirt and impurities on the inner threads. This structure can perform in-depth and comprehensive cleaning of the inner threads of the drill pipe, ensure the cleanliness and integrity of the inner threads, and help improve the stability and reliability of the drill pipe connection. Combined with the water spraying and flushing cleaning method, it can also reduce friction during the cleaning process, reduce wear on the threads, and extend the service life of the drill pipe.

[0065] As a further technical solution, it also includes: there are several cleaning arms 350, one end of the cleaning arm 350 is hinged to the water sleeve 310, and a cleaning space 420 is formed between the several cleaning arms 350; a guide rod 410 is arranged on the cleaning arm 350, and the guide rod 410 is used to guide the drill rod into the cleaning space 420; both ends of the elastic member 430 are respectively arranged on different cleaning arms 350, and the elastic member 430 is used to provide clamping force for the cleaning arm 350; one end of the connecting rod 440 is hinged to the cleaning arm 350, and the other end is hinged to the first cleaning rod 330. After the cleaning arm 350 is opened, the first cleaning rod 330 slides relative to the water sleeve 310.

[0066] In this embodiment, the design of multiple cleaning arms 350 can clean the drill rod from multiple directions simultaneously, improving the efficiency and comprehensiveness of cleaning and ensuring that the drill rod threads are fully cleaned. The guide rod 410 helps to guide the drill rod accurately into the cleaning space 420, making the cleaning operation more convenient and accurate, and reducing the time and error of alignment. The elastic member 430 provides clamping force for the cleaning arm 350, enabling the cleaning arm 350 to fit tightly against the drill rod, enhancing the cleaning effect, and adapting to drill rods of different diameters. The connection method of the connecting rod 440 realizes the linkage between the first cleaning rod 330 and the cleaning arm 350. The structure is ingenious, simplifies the operating steps, and improves the degree of automation of the equipment. When the cleaning arm 350 is opened, the first cleaning rod 330 automatically slides relative to the water jacket 310 for cleaning. This coordinated action can automatically adapt to the insertion and removal of the drill rod, reducing manual intervention, and improving work efficiency and operational convenience.

[0067] Reference Figures 2 to 5 As a further technical solution, it also includes: a box body 210 is set on the sliding seat 2; a main shaft 221 is rotatably set on the box body 210, the main shaft 221 passes through the box body 210, and the main shaft 221 has a through hole; a chuck 222 is set at one end of the main shaft 221, and the chuck 222 is used to clamp the drill rod.

[0068] In this embodiment, the sliding seat 2 slides on the drilling frame 190, so that the box body 210 and the components connected thereto can flexibly adjust their positions according to actual needs, further increasing the flexibility and adaptability of the drilling operation. The main shaft 221 is rotatably set on the box body 210, and the main shaft 221 has a through hole to facilitate the installation and operation of the drill rod, thereby improving the convenience of installing and replacing the drill rod. The chuck 222 can firmly clamp the drill rod to ensure that the drill rod will not loosen or fall off during the drilling process, thereby ensuring the stability and safety of the drilling work. This structural design helps to improve the accuracy and quality of drilling and reduce drilling deviations caused by loose or inaccurate position of the drill rod. The synergistic effect of the overall structure enables the coal mine drilling rig to complete the work task more efficiently and accurately during the directional drilling process, thereby improving the efficiency and benefits of coal mining.

[0069] As a further technical solution, the main shaft 221 has teeth 223 and also includes: a second rotating driving member 224 is arranged on the box body 210, and the second rotating driving member 224 has a gear 225, which engages with the teeth 223. When the gear 225 rotates, the main shaft 221 rotates synchronously.

[0070] In this embodiment, this transmission method has a high transmission efficiency and can effectively transmit the power of the second rotating drive member 224 to the main shaft 221, reducing energy loss and improving energy utilization. The compact structure and small footprint are conducive to the optimization and layout of the overall structure of the coal mine drill rig, enabling it to operate more flexibly in the narrow underground environment of a coal mine. The meshing transmission has high reliability and can maintain a good operating state in the harsh working environment of a coal mine, reducing the probability of failure and reducing maintenance and downtime. Through the cooperation of the second rotating drive member 224 and the teeth 223 of the gear 225, precise control of the rotation of the main shaft 221 is achieved, further enhancing the directional function of the coal mine drill rig and improving the controllability and accuracy of drilling.

[0071] Reference Figures 2 to 9 As a further technical solution, it also includes: the first telescopic members 231 have two, which are symmetrically arranged on the clamping seat 230, and the first telescopic member 231 has a first telescopic end; the clamping plate 232 is arranged on the first telescopic end, and the clamping plate 232 has a clamping groove 233. After the first telescopic member 231 is actuated, the clamping grooves 233 on the two different clamping plates 232 approach or move away from each other.

[0072] In this embodiment, the combined structure of the clamping seat 230, the first telescopic member 231 and the clamping plate 232 can stably clamp the drill rod or related components after the sliding seat 2 slides and adjusts its position, thereby increasing stability and safety during the drilling process. The two symmetrically arranged first telescopic members 231 and the clamping plate 232 cooperate with each other through the clamping groove 233 to provide a uniform clamping force, ensuring the firmness and balance of the clamping. The movement of the first telescopic member 231 can flexibly control the approach or distance of the clamping groove 233, making it convenient to adjust the clamping according to drill rods or components of different diameters, thereby improving the versatility and adaptability of the equipment. During the drilling process, effective clamping can reduce the vibration and shaking of the drill rod, improve the accuracy and quality of the drilling, and avoid drilling deviations caused by unstable drill rods. This clamping structure helps to protect the drill rod and related components, extend their service life, and also reduces the safety risks caused by loose or falling components.

[0073] As a further technical solution, the clamping seat 230 has several mounting grooves 234 and also includes: several cavas 240 that are detachably arranged on the clamping seat 230, and the cavas 240 are arc-shaped; several fixing blocks 250 that are detachably arranged in the mounting grooves 234, and the fixing blocks 250 are used to fix the cavas 240 on the clamping seat 230.

[0074] In this embodiment, the combined structure of the clamping seat 230, the first telescopic member 231 and the clamping plate 232 can stably clamp the drill rod or related components after the sliding seat 2 slides and adjusts its position, thereby increasing stability and safety during the drilling process. The two symmetrically arranged first telescopic members 231 and the clamping plate 232 cooperate with each other through the clamping groove 233 to provide a uniform clamping force, ensuring the firmness and balance of the clamping. The movement of the first telescopic member 231 can flexibly control the approach or distance of the clamping groove 233, making it convenient to adjust the clamping according to drill rods or components of different diameters, thereby improving the versatility and adaptability of the equipment. During the drilling process, effective clamping can reduce the vibration and shaking of the drill rod, improve the accuracy and quality of the drilling, and avoid drilling deviations caused by unstable drill rods. This clamping structure helps to protect the drill rod and related components, extend their service life, and also reduces the safety risks caused by loose or falling components.

[0075] As a further technical solution, the clamping seat 230 has a water hole 241 and also includes: a cleaning plate 260 arranged in the clamping groove 233, the cleaning plate 260 is also arc-shaped, and the cleaning plate 260 has the same shape as the fixed block 250. The cleaning plate 260 has a water space 270 and a water hole 280 connected to the water hole 241, and the water hole 280 is used for spraying and cleaning the outer wall of the drill pipe.

[0076] In this embodiment, the arrangement of the water hole 241, the water space 270, and the water hole 280 forms a pathway for cleaning water, enabling real-time cleaning of the outer wall of the drill rod during the drill rod withdrawal process after drilling is completed, effectively removing attached mud and debris, keeping the drill rod clean, and reducing wear and malfunction. The cleaning plate 260 is disposed within the clamping groove 233 and can be cleaned while clamping the drill rod, without occupying additional space, making the structure more compact, and not affecting normal clamping and drilling operations. Cleaning the outer wall of the drill rod helps improve drilling accuracy and efficiency, prevents dust and debris from interfering with drilling, and also extends the service life of the drill rod. Real-time cleaning can reduce dust flying, improve the working environment, and reduce the harm of dust to the health of operators, thus meeting the environmental protection and safety requirements of coal mine operations. This integrated cleaning design reduces the need for separate cleaning equipment and operating steps, simplifies the overall structure and operating procedures of the coal mine drilling rig, and improves work efficiency.

[0077] As a further technical solution, the clamping seat 230 is provided with a water guide port 290 , which is located at the lowest point of the mounting groove 234 . The water guide port 290 is used to guide and collect water sprayed from the water hole 241 .

[0078] In this embodiment, the water guide 290 is located at the lowest point of the mounting groove 234. It can effectively collect water that flows down after being sprayed through the water hole 241, preventing water from accumulating on the clamping seat 230, and keeping the work area dry and clean. The guidance and collection of the sprayed water helps to recycle and reuse water resources, reduce water waste, and meet energy conservation and environmental protection requirements. It prevents water overflow from causing a slippery workplace, reduces safety hazards, and ensures the safety of operators. Centralized water collection facilitates subsequent unified processing and reduces pollution to the work environment.
