Description

Technical Field

[0001] This invention relates to the field of drilling technology, and more specifically, to a mobile device for coal mine drilling rigs. Background Technology

[0002] In some coal mine underground mining operations, large equipment is difficult to access for construction processes such as gas extraction, water exploration, roof anchoring, and roadway support. Therefore, drilling operations must be completed using small to medium-sized drilling rigs. The efficiency, stability, and automation level of these drilling rigs directly determine the progress and safety of underground coal mine construction. Currently, drilling equipment used in underground coal mine drilling operations is mainly divided into two categories: modular fixed drilling rigs and conventional tracked mobile drilling rigs. Modular drilling rigs have a fragmented structure and low integration, making equipment handling and disassembly extremely reliant on manual assistance. They have poor mobility and are only suitable for fixed-point drilling operations, unable to meet the needs of continuous construction in multiple locations and scenarios underground. Tracked mobile drilling rigs, while possessing autonomous mobility, are large and heavy, poorly adaptable to narrow underground roadways, and have limited functionality. Drill rod storage, transportation, and loading / unloading are mostly independent external structures, resulting in low overall integration and occupying a large amount of roadway space, making them unsuitable for small to medium-sized applications. Summary of the Invention

[0003] This invention proposes a mobile device for coal mine drilling rigs, which solves the stability problem of small and medium-sized drilling rigs in related technologies.

[0004] The technical solution of the present invention is as follows: A mobile device for coal mine drilling rigs, comprising: The vehicle body has a carriage, which has a drill pipe compartment and a drilling compartment. The drilling compartment is used to install the drilling rig, and the drill pipe compartment is used to provide drill pipes to the drilling rig. A drill pipe loading and unloading component is located at the rear end of the drilling chamber and is used to receive the drill pipe in the drill pipe chamber and install it onto the drilling rig. A diagonal brace fixing member is swayably disposed on the underside of the vehicle body, and the diagonal brace fixing member is used to abut against the ground after swaying.

[0005] As a further technical solution, the drill pipe loading and unloading component includes: The guide plate, of which there are at least two, is inclinedly arranged inside the drilling chamber and is used to guide the drill rod as it moves into the drilling chamber; Two centering rollers are rotatably mounted on one side of the guide plate and located behind the drilling rig. The drill rod falls onto the centering rollers via the guide plate to achieve collinearity between the drill rod and the drill rod axis of the drilling rig. A clamping device is provided, which is raised and lowered inside the drilling chamber and located on one side of the guide plate. After the clamping device is lowered, it presses against the drill rod. A clamping wheel is provided at the end of the clamping device. After the clamping wheel rotates, it drives the drill rod to be threadedly connected to the drill rod on the drilling machine. A clamping cylinder is disposed on one side of the centering roller and is used to clamp the drill rod on the drilling rig. A tightening member is rotatably and movable within the drilling chamber and located on the side of the centering roller away from the clamping cylinder. After moving, it is used to clamp the drill rod on the centering roller and drive the drill rod to rotate to a specified torque.

[0006] As a further technical solution, it also includes: A storage rack is provided inside the drill rod compartment. The storage rack has several storage compartments, each of which is used to accommodate a row of drill rods. The lower side of each storage compartment has a discharge port. There is a drilling space between the bottom of the discharge port and the bottom of the drill rod compartment. The height of the drilling space is greater than the diameter of the drill rod and less than 1.5 times the diameter of the drill rod. A pusher is provided on one side of the storage rack and is used to push the drill rod in the drilling space onto the guide plate. A stop is oscillatingly disposed on the side of the guide plate. The stop is used to prevent the drill rod in the drilling space from entering the rear section of the guide plate without being pushed. After the pusher pushes the drill rod, the stop is pushed and oscillated by the drill rod so that one of the drill rods enters the centering roller.

[0007] As a further technical solution, it also includes: A rotating material feeder is rotatably disposed inside the carriage and located between the two guide plates. The rotating material feeder has a feeding claw. After the rotating material feeder rotates, it pushes the drill rod above the centering roller to prevent the drill rod from being deflected and unable to fall to the centering roller.

[0008] As a further technical solution, the pusher has a support plate, and the upper side of the support plate has several rotatably arranged rollers. The support plate is used to prevent the drill rod from falling into the drilling space. The pusher claw has a pusher part, and the upper end of the pusher part is oscillatingly connected to a pusher plate. The pusher plate is an arc-shaped plate, and a rotating wheel is provided on the pusher plate. Both the rotating wheel and the rollers are used to abut against the drill rod. After the pusher plate oscillates, it pushes the drill rod.

[0009] As a further technical solution, the stop has a groove, the groove is arc-shaped, the radius of the groove is greater than the radius of the drill rod, the arc angle of the groove is less than 60 degrees, and a roller is rotatably provided at the upper end of the groove to avoid scratching the drill rod when the drill rod moves.

[0010] As a further technical solution, the vehicle body includes a base and a swing bucket, the swing bucket including the drill pipe chamber and the drilling chamber, and further includes: The telescopic component is mounted on the swing bucket, and the output end of the telescopic component is equipped with a swing abutment. The swing abutment is used to abut against the tunnel wall opposite to the feed direction of the drill bit during tunnel oblique construction.

[0011] As a further technical solution, the inclined brace fixing component includes a driving cylinder and a fixed cylinder. The driving cylinder is oscillatingly mounted on the vehicle body. The output end of the driving cylinder is rotatably connected to the fixed cylinder. The output end of the fixed cylinder is provided with a fixed abutment, which is used to abut against the ground.

[0012] As a further technical solution, it also includes: An anti-detachment component is provided above the storage bin to prevent the drill rod inside the storage bin from falling off when the swing bucket swings. An elastic element, one end of which acts on the anti-detachment element and the other end of which acts on the storage compartment, provides the anti-detachment element with a force to press the drill rod.

[0013] As a further technical solution, it also includes: The unloading claw is located on one side of the clamping device and is used for unloading during the disassembly of the drill rod.

[0014] The working principle and beneficial effects of this invention are as follows: This invention integrates the drill pipe compartment and drilling compartment into a single vehicle body, achieving integrated functions for drill pipe storage, drilling rig installation, and drill pipe loading and unloading. This significantly simplifies the overall structure of coal mine drilling equipment, reduces the space required for underground equipment deployment, and adapts to the narrow working environment of coal mine tunnels. The rear-mounted drill pipe loading and unloading mechanism enables automated drill pipe docking and installation, replacing the traditional manual handling and docking method, effectively reducing labor intensity. Simultaneously, the swingable inclined brace provides ground support during operation, effectively offsetting the high-frequency vibrations and axial impact forces generated during drilling, preventing equipment deviation, slippage, and overturning, significantly improving the stability and safety of equipment operation. Furthermore, the retractable structure does not affect the flexibility of equipment movement and transportation, balancing operational stability and equipment mobility. Attached Figure Description

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Reference Figures 1-6 This invention provides a first embodiment of a mobile device for coal mine drilling rigs, comprising a vehicle body 1, a drill rod loading / unloading component 2, and a diagonal bracing component 3. The vehicle body 1 integrates a carriage structure, inside which are two independent functional cavities: a drill rod chamber 102 and a drilling chamber 103. The drilling chamber 103 provides a dedicated installation and fixing space for the drilling rig, enabling stable assembly and operational positioning. The drill rod chamber 102 serves as a storage and supply cavity for drill rods, continuously supplying drill rod materials to the drilling rig assembled within it. The drill rod loading / unloading component 2 is fixedly mounted at the rear end of the drilling chamber 103, corresponding to the discharge direction of the drill rod chamber 102. It accurately receives the drill rods output from the drill rod chamber 102 and automatically completes the docking and installation of the drill rods with the drilling rig. The diagonal brace fixing component 3 is installed on the lower side of the vehicle body 1 using a swingable assembly method. During the movement and transportation of the equipment, the diagonal brace fixing component 3 is folded up and stored close to the vehicle body 1 without affecting the passage of the equipment. When the equipment arrives at the underground working point in the coal mine, the diagonal brace fixing component 3 swings outward and unfolds, with its bottom end face tightly abutting against the underground ground, thus achieving overall support and fixation of the equipment.

[0022] This embodiment integrates the drill pipe compartment 102 and the drilling compartment 103 within the vehicle body 1, achieving integrated functions of drill pipe storage, drilling rig installation, and drill pipe loading and unloading. This significantly simplifies the overall structure of coal mine drilling equipment, reduces the space required for underground equipment deployment, and adapts to the narrow working environment of underground coal mine tunnels. The rear-mounted drill pipe loading and unloading component 2 enables automated drill pipe docking and installation, replacing the traditional manual handling and docking method, effectively reducing labor intensity. Simultaneously, the swingable inclined brace fixing component 3 provides ground support during operation, effectively offsetting the high-frequency vibrations and axial impact forces generated during drilling operations. This prevents equipment from shifting, slipping, or overturning, significantly improving the stability and safety of equipment operation. Furthermore, the retractable structure does not affect the flexibility of equipment movement and transportation, balancing operational stability and equipment mobility.

[0023] In some embodiments, the drill rod loading and unloading component 2 includes a guide plate 201, a centering roller 202, a clamping device 203, a clamping cylinder 205, and a tightening component 206. At least two guide plates 201 are installed obliquely and fixedly inside the drilling chamber 103, forming an oblique guide channel to guide and transport the drill rod output from the drill rod chamber 102, ensuring the drill rod moves smoothly into the working area of ​​the drilling chamber 103. Two centering rollers 202 are respectively rotatably mounted on one side of each guide plate 201 and precisely positioned directly behind the drilling rig. The drill rod slides down guided by the guide plates 201 and is then connected above the centering rollers 202. Through the limiting support of the two sets of centering rollers 202, the position of the drill rod can be forcibly calibrated, ensuring that the drill rod axis is collinear with the original drill rod axis of the drilling rig, eliminating docking deviations. The clamping device 203, with a liftable assembly structure, is installed inside the drilling chamber 103, on the side of the guide plate 201. During operation, the clamping device 203 moves downwards and upwards, pressing its bottom against the drill rod to be connected, thus achieving vertical positioning of the drill rod. A clamping wheel 204 is rotatably mounted at the end of the clamping device 203. The clamping wheel 204 can rotate actively, driving the bottom-positioned drill rod to rotate through friction, assisting in the initial thread connection between the drill rod and the drilling rig. A clamping cylinder 205 is fixedly installed on one side of the centering roller 202. During operation, it can extend its clamping end to clamp and fix the drill rod already assembled on the drilling rig, preventing the original drill rod from rotating or shifting, and providing a stable reference for the connection of the new drill rod. The tightening component 206 is installed inside the drilling chamber in a rotatable and linearly movable assembly manner, and is located on the side of the centering roller 202 away from the clamping cylinder 205. After the drill rod is positioned by the centering roller 202, the tightening component 206 moves forward to clamp the drill rod to be connected, and then drives the drill rod to rotate precisely to reach the specified tightening torque according to the construction standard, thus completing the precise assembly of the drill rod.

[0024] This embodiment utilizes a guide plate 201 to ensure smooth guiding and conveying of the drill rod, preventing jamming and deviation during transport and ensuring continuous material supply. Paired centering rollers 202 ensure precise alignment of the drill rod shaft, completely resolving the problems of shaft misalignment and thread wear jamming that often occur with traditional manual drill rod assembly. This effectively protects the drill rod's thread structure and reduces component wear. A clamping cylinder 205 secures the existing drill rod, while a lifting clamping device 203 limits and fixes the new drill rod. This dual-structure limitation significantly improves the stability of the drill rod assembly process. Simultaneously, the combination of clamping wheels 204 for pre-tightening and tightening components 206 for precise torque control enables automated, high-precision thread assembly of the drill rod. This not only significantly improves assembly efficiency but also precisely controls assembly torque, preventing drill rod loosening due to insufficient torque and thread breakage or deformation due to excessive torque. This significantly improves the forming quality and operational efficiency of coal mine drilling operations.

[0025] In some embodiments, the system further includes a storage rack 4, a pusher 5, and a stop 6. The storage rack 4 is fixedly assembled inside the drill rod chamber 102. The storage rack 4 is evenly divided into several independent storage chambers 401. Each storage chamber 401 can stack multiple drill rods in a single row, achieving classified and orderly storage of drill rods. Each storage chamber 401 has a through-type discharge port 402 on its lower side. A drilling space 403 is reserved between the bottom of the discharge port 402 and the bottom plane of the drill rod chamber 102. The height of the drilling space 403 is set to be greater than the outer diameter of the drill rod and less than 1.5 times the outer diameter of the drill rod, allowing only a single drill rod to pass laterally, thus achieving single-rod discharge limit. The pusher 5 is assembled on the side of the storage rack 4 at the corresponding position, facing the drilling space 403. It can actively push the single drill rod that falls into the drilling space 403, pushing the drill rod to the guiding starting position of the guide plate 201. The stop 6 is installed on the side of the guide plate 201 in a swingable assembly manner. Under normal conditions, the stop 6 is in a blocking state, which can prevent the drill rod in the drilling space 403 from sliding into the working area of ​​the rear section of the guide plate 201 on its own when it is not pushed by the pusher 5. When the pusher 5 pushes the drill rod forward, the end of the drill rod abuts against and pushes the stop 6 to swing passively, releasing the blocking limit, allowing only a single drill rod to smoothly enter the working position of the centering roller 202. After the pushing is completed, the stop 6 automatically resets to the blocking position.

[0026] This embodiment utilizes a multi-compartment storage rack 4 to achieve orderly and categorized storage of drill rods. Compared to traditional haphazard stacking, this effectively avoids problems such as drill rods bumping and wearing each other, chaotic placement, and inconvenient retrieval, thus improving the safety and orderliness of drill rod storage. By limiting the height of the drilling space 403, single-rod orderly discharge is achieved, preventing material jamming, blockage, and equipment malfunctions caused by multiple drill rods being discharged simultaneously. In conjunction with the resettable swing stop 6 and the pusher 5, quantitative, orderly, and precise feeding of drill rods is achieved, strictly ensuring that only one drill rod enters the assembly station at a time. This provides a stable material foundation for subsequent automated alignment, clamping, and tightening operations, significantly improving the stability and continuity of automated equipment operation, reducing the frequency of manual intervention, and adapting to the needs of continuous drilling operations in coal mines.

[0027] In some embodiments, the rotating material feeder 7 is rotatably mounted inside the carriage and precisely positioned in the middle of the two guide plates 201. A material feeder claw 701 is fixedly mounted on the outer side of the rotating material feeder 7. When the drill rod is pushed from the drilling space 403 onto the guide plate 201 and its position shifts or tilts, preventing it from naturally sliding down above the centering roller 202, the rotating material feeder 7 actively rotates, causing the material feeder claw 701 to swing synchronously. Through the pushing and correcting action of the material feeder claw 701, the shifted and tilted drill rod is pushed and corrected to the centered position directly above the centering roller 202, forcibly completing the drill rod position correction and ensuring the drill rod is accurately positioned.

[0028] This embodiment adds a rotating material-pushing component 7 in the middle of the double guide plates 201. Utilizing the dynamic material-pushing correction function of the material-pushing claw 701, it effectively solves the problems of skewing and inaccurate placement caused by dimensional deviations, slide wear, and uneven pushing force during drill rod conveying. This completely avoids situations where the drill rod cannot fall onto the centering roller 202 due to skewing, leading to assembly interruptions. By actively correcting the drill rod position, it further improves the drill rod placement accuracy and centering pass rate, ensuring smooth drill rod docking processes, significantly reducing the probability of equipment jamming and downtime due to operational failures, effectively improving the stability and reliability of continuous equipment operation, and further enhancing the overall efficiency of coal mine drilling operations.

[0029] In some embodiments, the pusher 5 is provided with a support plate 501. A plurality of freely rotatable rollers 502 are evenly mounted on the upper side of the support plate 501. The support plate 501 is positioned directly opposite the bottom of the drilling space 403, catching any falling drill rods and preventing them from falling directly to the bottom of the drilling space 403 and causing damage or positional displacement. It also provides stable support for pushing the drill rod. The rotating feeder 7 has a feeder claw 701 integrally formed with a feeder part 702. The upper end of the feeder part 702 is equipped with an arc-shaped feeder plate 703 via a swing connection. The arc-shaped feeder plate 703 can adapt to the cylindrical outer wall structure of the drill rod, resulting in a better fit. A rotating wheel 704 is rotatably mounted on the plate body of the feeding plate 703. The rotating wheel 704 and the roller 502 on the support plate 501 directly roll and abut against the outer wall of the drill rod. When the drill rod is not placed horizontally, the feeding plate 703 swings and pushes the drill rod through the rolling contact between the rotating wheel 704 and the drill rod after it is in contact with the outer wall of the drill rod, thus completing the precise displacement correction and conveying of the drill rod.

[0030] In this embodiment, the support plate 501 supports the drill rod, preventing it from falling, impacting, deforming, or wearing down, effectively protecting the structural integrity of the drill rod and reducing material loss. The rollers 502 on the support plate 501, in conjunction with the rotating wheels 704 on the feed plate 703, convert the sliding friction between the drill rod and the pushing and straightening structure into rolling friction, significantly reducing friction during the pushing and straightening process. This not only reduces the equipment's pushing load and energy consumption but also completely avoids scratches and wear on the drill rod's outer wall caused by hard friction. Simultaneously, the swingable arc-shaped feed plate 703 can adapt to drill rods with varying degrees of dimensional deviation, resulting in a better fit, more precise straightening and pushing effect, further improving the stability and accuracy of drill rod delivery and positioning, extending the drill rod's service life, and reducing equipment maintenance costs.

[0031] In some embodiments, the stop 6 has an arc-shaped groove 602, the radius of which is greater than the outer radius of the drill rod, and the central angle of the arc of the groove 602 is less than 60 degrees. A roller 603 is rotatably mounted on the inner side of the upper end of the groove 602. The roller 603 can rotate freely, and during operation, the end of the drill rod rolls into contact with the inner wall of the groove 602 and the roller 603 to achieve sliding avoidance. Under normal conditions, the groove 602 engages and limits the drill rod to prevent it from sliding on its own; during the pushing operation, the drill rod moves forward, pushing the stop 6 to swing, while the roller 603 rotates to assist the drill rod in smoothly moving out of the groove 602.

[0032] This embodiment, by limiting the radius and angle parameters of the arc-shaped groove 602, ensures that the groove 602 effectively limits and stops the drill rod under normal conditions, preventing the drill rod from moving around. It also avoids the problem of the groove 602 covering too large an area of ​​the drill rod, which could cause the drill rod to jam or become stuck, thus ensuring the accuracy of single-pole feeding. By adding a rotatable roller 603 to the upper end of the groove 602, the sliding friction between the drill rod and the stop 6 is converted into rolling friction. This completely solves the problem of traditional hard stops easily scratching and damaging the outer wall of the drill rod, effectively protecting the surface integrity of the drill rod and preventing a decrease in corrosion resistance and fatigue resistance caused by wear on the outer wall. At the same time, it significantly reduces the pushing resistance of the drill rod, making the feeding process smoother and more stable, and improving the overall smoothness of the equipment operation.

[0033] In some embodiments, the vehicle body 1 includes a base 104 and a swingable swing bucket 105. The swing bucket 105 is internally divided into a drill rod chamber 102 and a drilling chamber 103, and can be swung and adjusted relative to the base 104 as needed for operation. The equipment also includes a telescopic component 8, which is fixedly mounted on the outer wall of the swing bucket 105. The telescopic output end of the telescopic component 8 is equipped with a swing abutment component 801 via a swing connection. When tunnel inclined drilling is carried out in a coal mine, the swing bucket 105 is adjusted to swing to the corresponding inclined working angle. Then the telescopic component 8 extends, causing the swing abutment component 801 at its end to abut against the tunnel rock wall opposite to the drill bit feed direction. By adaptively swinging the swing abutment component 801 to adapt to the rock wall angle, reverse support and limit are achieved when the equipment is tilted. Correspondingly, the swing of the material feeding plate 703 can also stably push the drill rod to move after the swing bucket 105 swings.

[0034] This embodiment utilizes a separate swing structure of the base 104 and the swing bucket 105 to achieve flexible adjustment of the drilling angle, breaking the limitations of traditional fixed drilling rigs that can only operate vertically and horizontally. It can adapt to complex construction scenarios such as inclined drilling in coal mines and drilling at irregularly shaped points in roadways, significantly improving the equipment's operational adaptability. By adding a telescopic component 8 and a swingable abutment component 801, a reverse rock wall support force is formed during inclined construction, effectively counteracting the reverse thrust generated by the inclined feed of the drill bit. This prevents the swing bucket 105 from shifting under force or deflecting at an angle, precisely locking the drilling angle, ensuring the accuracy and verticality of inclined drilling, and significantly improving the overall stability of the equipment under inclined operation, eliminating drilling failures and equipment malfunctions caused by equipment shaking or shifting.

[0035] In some embodiments, the inclined support fixing member 3 of the material feeding plate 703 includes a driving cylinder 301 and a fixed cylinder 302. The cylinder end of the driving cylinder 301 is mounted on the lower side of the vehicle body 1 using a swing assembly method. The telescopic output end of the driving cylinder 301 is rotatably connected to the cylinder end of the fixed cylinder 302. A fixed abutment is fixedly mounted on the telescopic output end of the fixed cylinder 302. When the equipment is moved and transported, the driving cylinder 301 retracts, causing the fixed cylinder 302 to swing and retract as a whole, fitting against the bottom of the vehicle body 1 without occupying passage space. When the equipment is in place, the driving cylinder 301 extends, pushing the fixed cylinder 302 to swing and unfold. After adjusting to the vertical support angle, the fixed cylinder 302 extends, causing the end fixed abutment to press tightly against the underground ground, realizing multi-point support and fixing of the equipment.

[0036] This embodiment employs a dual-cylinder combined inclined brace fixing structure. The swinging and retraction of the support structure is achieved through the driving cylinder 301, adapting to switching between equipment movement and operation modes, offering high flexibility. The support height is adjusted via the fixing cylinder 302, adapting to the uneven ground environment of underground coal mines, ensuring full contact between the fixing components and the ground, and uniform force distribution, avoiding equipment instability caused by single-point suspended support. The dual-cylinder linkage structure provides strong support and stability, effectively resisting the vibration and impact generated by high-intensity drilling operations, locking the equipment's operating position from all directions, eliminating the risk of equipment slippage, tilting, and overturning, significantly improving the safety of high-risk underground operations. Simultaneously, the structure is simple, the operation is reliable, the failure rate is low, and it is suitable for harsh underground working environments.

[0037] In some embodiments, the system further includes an anti-detachment component 9 and an elastic component 10. The anti-detachment component 9 is fitted onto the upper opening of the storage chamber 401, blocking the upper opening of the storage chamber 401 and limiting the drill rods stacked inside the storage chamber 401. One end of the elastic component 10 is fixed to the inner wall of the anti-detachment component 9, and the other end is fixed to the side wall of the storage chamber 401. The elastic component 10 continuously provides a downward pressing elastic force to the anti-detachment component 9, ensuring that the anti-detachment component 9 always adheres to and presses against the uppermost drill rod inside the storage chamber 401. When the swing bucket 105 is adjusted by angle swing or the equipment vibrates, the pressing and limiting effect of the anti-detachment component 9 prevents the drill rods inside the storage chamber 401 from loosening, shifting, or falling due to vibration or changes in tilt angle.

[0038] This embodiment uses an elastic clamping anti-detachment component 9 above the storage bin 401. Relying on the continuous elastic force of the elastic component 10, the drill rod is adaptively clamped and limited. When the swing bucket 105 swings at multiple angles, the equipment moves and vibrates underground, or the drilling rig vibrates, the position of the drill rod inside the storage bin 401 is effectively locked, preventing the drill rod from slipping, falling, or scattering. This avoids the drill rod falling and damaging the equipment, affecting underground operation safety, and also prevents the drill rod from misaligning and blocking the discharge port 402, ensuring the continuous and smooth operation of the feeding system. The elastic clamping structure can adapt to slight changes in the height of the drill rod stack, always maintaining an effective clamping state. No manual adjustment is required, resulting in a high degree of automation. It is suitable for multi-angle operating conditions of the equipment, improving the safety and stability of equipment operation.

[0039] In some embodiments, a discharge claw 11 is also included. The discharge claw 11 is fixedly mounted on the side of the clamping device 203 and moves up and down synchronously with the clamping device 203. It is specifically used for the disassembly and unloading of drill rods after drilling operations are completed. When it is necessary to disassemble worn, scrapped, or completed drill rods, the clamping device 203 descends to its position, driving the discharge claw 11 to move down synchronously and engage with the drill rod body to be disassembled. Through the clamping, limiting, and pulling action of the discharge claw 11, in conjunction with the tightening structure of the equipment, the drill rod threads are loosened, realizing the automated unloading and removal of the drill rod.

[0040] This embodiment integrates a discharge claw 11 on the side of the clamping device 203, achieving synchronous action based on the existing clamping and lifting structure. No additional drive mechanism is required, resulting in a simplified structure and low modification costs. The discharge claw 11 specifically enables drill rod disassembly and unloading, filling the functional gap of equipment that can only automatically load rods but not automatically unload them. This forms a fully automated operation system for automatic drill rod loading, assembly, disassembly, and unloading, completely replacing the high-risk manual disassembly of drill rods and avoiding the safety risks of bumps and pinches that can occur during manual disassembly in confined underground spaces. Simultaneously, the discharge claw 11 has strong linkage with the overall machine structure, ensuring precise and stable unloading action, significantly improving drill rod disassembly efficiency, shortening the time spent on rod replacement and maintenance during drilling operations, and effectively improving the overall operating efficiency and safety of coal mine drilling rigs.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
