Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to a multi-functional top-cutting drill rig. Background Technology

[0002] In various underground engineering fields such as coal mining and metal mining, roof cutting and anchor bolt support are key procedures to ensure mining safety and maintain roadway stability. However, traditional construction methods and related equipment have many limitations and problems.

[0003] In the early days, roof cutting and anchor bolting operations relied on specialized equipment with single functions. When performing roof cutting, the roof cutting drilling rig had to be transported to the work site. These rigs were typically large and heavy, making transportation extremely inconvenient in the narrow and complex underground tunnel networks. Due to the lack of flexible height adjustment capabilities, operators often struggled to accurately position the rig at the optimal working height when facing roofs of varying tunnel heights, affecting the roof cutting effect and potentially causing safety accidents due to operational difficulties. Furthermore, the roof rock characteristics varied across different mining areas, and roof cutting drilling rigs with single-parameter settings could not adapt to the varying rock hardness and structure, resulting in low roof cutting efficiency, inability to effectively control roof collapse, and safety hazards for subsequent mining operations.

[0004] In terms of anchor bolt construction, traditional anchor bolt drilling rigs also have many shortcomings. On the one hand, their versatility is poor. It is difficult to quickly and accurately adjust parameters such as anchor bolt length, spacing, and installation angle required for different mines and different roadway locations, often requiring a significant amount of time for manual calibration, thus reducing construction efficiency. On the other hand, during frequent underground transport, independent anchor bolt drilling rigs are easily affected by the narrow spaces of the roadways, leading to collisions, scratches on the equipment casing, and even damage to critical components. This not only increases maintenance costs but may also delay the construction progress.

[0005] Furthermore, in traditional construction methods, roof cutting and anchor bolting require separate equipment deployment, which consumes significant time and effort in equipment allocation and relocation. In the complex underground environment, the distances between different work sites are vast, and tunnel conditions are poor. Each equipment relocation presents transportation challenges, such as difficulty turning around in narrow bends and the need for repeated disassembly and reassembly of equipment when traversing low-lying areas. This severely restricts construction continuity and significantly extends the overall project cycle. At the same time, frequent equipment relocation greatly increases safety risks; collisions and falls during transportation are frequent, threatening the lives of underground workers and the integrity of equipment.

[0006] Furthermore, since the top-cutting drilling rig and the anchor drilling rig are set up separately, each occupying a large space, when moving in the tunnel, the limited space often causes passage to be obstructed, requiring manual clearing of surrounding obstacles or temporary disassembly of the equipment. The operation is cumbersome and inefficient, limiting the mobility and operating range of the equipment, and making it difficult to meet the complex and ever-changing needs of underground engineering.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] 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.

[0054] Reference Figures 1-2 The first embodiment of this utility model proposes a multi-functional top-cutting drilling rig, including a frame 1, a lifting platform 2 which is lifted and mounted on the frame 1, a top-cutting drilling machine 3 which is mounted on one side of the lifting platform 2, and there is at least one top-cutting drilling machine 3. An anchor drilling machine 4 is mounted on one side of the lifting platform 2 and is located on the side of the direction of travel of the top-cutting drilling rig.

[0055] In this embodiment, the multi-functional roof-cutting drilling rig integrates the roof-cutting drilling machine 3 and the anchor bolt drilling machine 4 on one side of the lifting platform 2, realizing the fusion of two important functions: roof-cutting operation and anchor bolt construction. In underground engineering such as coal mining, roof-cutting operation plays a crucial role in controlling roof collapse and improving stress distribution in the mining area, while anchor bolt construction is an important means of effectively supporting the roof and sidewalls of the roadway and ensuring the safety and stability of the working space. One drilling rig possesses both functions, eliminating the need to separately call upon different equipment to complete the corresponding tasks, greatly improving construction efficiency, reducing the time costs of equipment allocation and relocation, allowing for a more compact construction process, and enabling efficient connection between roof-cutting and anchor bolt support operations, ensuring the smooth progress of the entire underground project.

[0056] Different underground engineering environments and mining stages place varying requirements on roof cutting and anchor bolting. This drilling rig, equipped with a roof cutting drill 3 and an anchor bolting drill 4, can flexibly handle these diverse working conditions. For example, in areas with varying roof rock hardness, the roof cutting drill 3 can adjust drilling parameters to effectively cut the roof according to the actual situation; similarly, for situations where the length, spacing, and installation angle of anchor bolts vary, the anchor bolting drill 4 can also be adjusted accordingly to meet support specifications. This adaptability to different working conditions allows the drilling rig to be widely used in various underground mining projects such as coal mines and metal mines, improving the equipment's versatility and usability, and reducing the cost for companies that would otherwise need to equip themselves with multiple single-function devices for different working conditions.

[0057] The lifting platform 2 is mounted on the chassis 1, a design that provides flexible adjustment capabilities for the working height of the roof-cutting drill 3 and the anchor bolt drill 4. In underground engineering, the height of the roof is not constant; the distance between the roof and the ground varies in different roadways and at different mining stages. Through the lifting function of the lifting platform 2, operators can precisely adjust the roof-cutting drill 3 and the anchor bolt drill 4 to the appropriate working height based on the actual roof height, ensuring that roof cutting and anchor bolting are carried out at the optimal height, thus improving the accuracy and effectiveness of the operation.

[0058] The height adjustment of the lifting platform 2 not only helps match the working height but also optimizes the operator's field of vision and ease of operation. When the lifting platform 2 is adjusted to a suitable height, the operator can more clearly observe the specific conditions of the roof, such as rock texture and fissure distribution, thereby better controlling the drilling direction of the top-cutting drill 3 and the anchor bolt installation position of the anchor bolt drill 4, improving construction quality. At the same time, a suitable height also makes it easier for the operator to operate the drill rig, reducing problems such as awkward operation and difficulty in exerting force due to unsuitable height, further improving construction efficiency, ensuring operational safety, and reducing the risk of construction errors caused by inconvenience in operation.

[0059] By compactly arranging the top-cutting drill rig 3 and the anchor drilling rig 4 on the lifting platform 2, the space occupied by the drilling rig is effectively saved compared to dispersing them in different locations. This makes the entire multi-functional top-cutting drill rig more compact in structure, more flexible in movement within confined spaces such as roadways, and easier to relocate. In the complex underground roadway network, there are many narrow passages, and the drilling rig needs to be frequently moved between different work locations. The compact layout helps the drilling rig to pass smoothly through these narrow areas, reduces passage obstacles caused by space constraints, improves the mobility and range of use of the equipment, ensures that the equipment can reach all the locations that need to be constructed in a timely manner, and guarantees the continuity of construction.

[0060] Previously, using separate equipment for roof cutting and anchor bolting operations posed numerous safety risks during underground movement, such as collisions during transport and difficulties turning around in narrow tunnels. The multi-functional roof cutting drilling rig integrates these two functions, reducing the frequency of equipment movement and consequently mitigating these safety hazards during transport, thus ensuring the safety of underground personnel and equipment. Furthermore, reduced equipment movement avoids loosening or damage to components caused by frequent transfers, improving equipment stability and reliability, reducing maintenance workload, and further ensuring the continuity and efficiency of construction.

[0061] Furthermore, the top-cutting drilling rig 3 includes a first mounting base 301, which is rotatably arranged relative to the lifting platform 2. A first guide rail 302 is arranged on the first mounting base 301, and a first power head 303 is slidably arranged on the first guide rail 302. A clamp 304 is arranged at one end of the first guide rail 302 and is coaxially arranged with the first power head 303.

[0062] In this embodiment, the first mounting base 301 is rotatably mounted relative to the lifting platform 2. This design allows for flexible adjustment of the drilling angle of the roof-cutting drill 3. During underground engineering construction, the shape of the roof and the location requiring roof cutting are not always at fixed angles and directions. For example, at roadway bends, when the roof has tilt changes, or when encountering complex geological structures such as faults, the rotation of the first mounting base 301 allows the drill bit of the roof-cutting drill 3 to be aligned with target areas at different angles. This multi-angle adjustment capability greatly enhances the adaptability of the roof-cutting drill 3 to complex roof conditions, ensuring precise roof cutting according to construction requirements, improving the accuracy and effectiveness of roof cutting operations, and guaranteeing roof control throughout the entire mining space.

[0063] The rotation function of the first mounting base 301 not only adjusts the drilling angle but also optimizes the operator's field of vision and ease of operation. When performing roof cutting operations at different angles, the operator can rotate the first mounting base 301 to adjust the roof cutting drill rig 3 to an angle where they can clearly observe the contact between the drill bit and the roof, better control the drilling direction and depth, and promptly detect any abnormalities, such as changes in rock hardness or borehole deviation, and make corresponding adjustments. At the same time, a suitable angle also makes operating the drill rig more comfortable and convenient for the operator, reducing operational difficulties and inaccurate force application caused by poor angles, further improving the quality and efficiency of roof cutting operations and reducing the risk of construction errors.

[0064] The first guide rail 302 is mounted on the first mounting base 301, and the first power head 303 is slidably mounted on the first guide rail 302. This cooperative structure of the guide rail and power head provides a precise means of controlling the drilling depth and accuracy. During roof cutting operations, the drilling depth must be strictly controlled according to design requirements to ensure that the roof cutting effect meets expectations and that the subsequent collapse of the roof meets safety production requirements. The first power head 303 slides along the first guide rail 302, allowing operators to precisely control the travel distance of the power head according to construction standards, thereby accurately grasping the drilling depth and avoiding problems caused by drilling too deep or too shallow. For example, drilling too deep may lead to uncontrolled roof collapse, while drilling too shallow will not achieve an effective roof cutting effect.

[0065] The clamp 304 is located at one end of the first guide rail 302 and is coaxially arranged with the first power head 303. This plays a crucial role in ensuring the coaxiality of the borehole. During drilling, if the drill bit and the clamp are not coaxial, it can easily lead to borehole deviation, affecting the roof cutting effect and potentially damaging the drill bit and drilling rig. The coaxial arrangement ensures that the drill bit remains in a straight line during drilling, improving the straightness and accuracy of the borehole. This ensures uniform and reliable roof cutting quality, which is beneficial for the subsequent collapse of the roof in the expected direction and manner, increasing the success rate of the entire roof cutting operation and ensuring the safety and stability of underground engineering construction.

[0066] Furthermore, the anchor drilling rig 4 includes a second mounting base 401, which is rotatably arranged relative to the lifting platform 2. A second guide rail 402 is mounted on the second mounting base 401, and a second power head 403 is slidably mounted on the second guide rail 402. A guide sleeve 404 is mounted on one end of the second guide rail 402 and is coaxially arranged with the second power head 403.

[0067] In this embodiment, the second mounting base 401 is rotatably mounted relative to the lifting platform 2. This design allows the anchor drilling rig 4 to flexibly adjust the angle of anchor bolt installation. In underground engineering, the roof, sides, and other parts of the tunnel requiring anchor bolt support are not always in a regular horizontal or vertical state. For example, at tunnel bends, in areas tilted due to geological structures, or in tunnels with different cross-sectional shapes, the rotation of the second mounting base 401 allows the drill bit of the anchor drilling rig 4 to accurately align with the support position at various angles for anchor bolt installation. This multi-angle adjustment capability greatly enhances the adaptability of the anchor drilling rig 4 to complex support conditions, ensuring that the anchor bolts can be driven into the rock mass at the designed angle, thereby effectively exerting their support function and ensuring the stability and safety of the entire underground engineering space.

[0068] The rotating function of the second mounting base 401 not only facilitates the adjustment of the construction angle but also optimizes the operator's field of vision and operational convenience during anchor bolt construction. When working on support positions at different angles, the operator can rotate the second mounting base 401 to adjust the anchor bolt drilling rig 4 to an angle that allows for a clear observation of the anchor bolt driving process. This enables better control of the anchor bolt drilling direction, depth, and angle, allowing for timely detection of problems such as changes in rock mass structure or abnormal anchor bolt drilling, and prompting appropriate adjustments. Simultaneously, a suitable angle makes operating the drilling rig more comfortable and convenient, reducing operational difficulties and inaccurate force application caused by poor angles. This further improves the quality and efficiency of anchor bolt construction and reduces the risk of construction errors.

[0069] The second guide rail 402 is mounted on the second mounting base 401, and the second power head 403 is slidably mounted on the second guide rail 402. This structure provides a precise means of controlling the depth and accuracy of the anchor bolt installation. In anchor bolt support operations, strictly controlling the driving depth of the anchor bolt is crucial to ensuring the support effect. Different rock mass conditions and support design requirements correspond to specific anchor bolt driving depth standards. The second power head 403 slides along the second guide rail 402, allowing operators to precisely control the travel distance of the power head according to construction specifications. This ensures accurate control of the anchor bolt installation depth and avoids problems caused by driving the anchor bolt too deep or too shallow. Driving it too deep may waste materials and affect subsequent construction, while driving it too shallow will not provide sufficient anchoring force, affecting the support effect.

[0070] The guide sleeve 404 is located at one end of the second guide rail 402 and is coaxially arranged with the second power head 403. This plays a crucial role in ensuring the coaxiality of the anchor bolt installation. During anchor bolt drilling, if the anchor bolt and the guide sleeve are not coaxial, it can easily lead to skewed installation of the anchor bolt, affecting its anchoring effect in the rock mass, and may even prevent the anchor bolt from performing its support function properly. The coaxial arrangement ensures that the anchor bolt remains in a straight line during drilling, improving the straightness and accuracy of the anchor bolt installation. This ensures that each anchor bolt is accurately driven into the rock mass according to design requirements, enhancing the overall stability of the anchor bolt support system and guaranteeing the safety and reliability of underground engineering construction.

[0071] Furthermore, it also includes a control console 5, which is set on the lifting platform 2. There are several control consoles 5, which control the top cutting drill 3 or the anchor drill 4 respectively. The track 6 is set on the frame 1 and is used to control the movement of the frame 1. The power unit 7 is set on the lifting platform 2 and is used to drive the first power head 303 and the second power head 403 to rotate.

[0072] In this embodiment, several control consoles 5 are configured, each controlling either a top-cutting drill 3 or an anchor bolt drill 4. This one-to-one control method greatly improves the accuracy and convenience of equipment operation. During construction, top-cutting and anchor bolt support operations have different parameter requirements and operational characteristics. For example, when cutting the top, the drilling angle, depth, and rotation speed of the top-cutting drill 3 need to be controlled according to the characteristics of the roof rock. When installing anchor bolts, the corresponding parameters of the anchor bolt drill 4 need to be controlled according to the support design. Through their independent control consoles 5, operators can make precise adjustments to the operation of each drill rig based on its specific situation, avoiding the problems of parameter confusion and operational inconvenience that may occur when using a single control console to control multiple devices. This ensures that each drill rig operates according to the optimal construction parameters, improving construction quality and efficiency.

[0073] Multiple control consoles 5 are mounted on the lifting platform 2, allowing operators to control the top-cutting drilling rig 3 and the anchor drilling rig 4 from a relatively centralized location. This eliminates the need to move between different locations to switch operations, improving operational convenience and work efficiency. Furthermore, during centralized operation, operators can more easily observe the working status of each drilling rig and the overall situation of the construction area. This facilitates comprehensive management and coordination of the entire construction process, enabling timely detection and resolution of potential problems. For example, if a drilling rig experiences abnormal vibration or drilling obstruction, operators can react quickly, adjusting parameters on the corresponding control console 5 or taking other countermeasures to ensure smooth construction and optimize the collaborative operation between equipment.

[0074] Tracks 6, mounted on the chassis 1, provide powerful driving force and excellent adaptability for the chassis's movement. In the complex environment of underground engineering, tunnel surfaces are often uneven, potentially containing water accumulation, mud, and protruding rocks. Compared to traditional wheeled locomotives, tracks 6 are better suited to these harsh conditions, ensuring the drilling rig can move smoothly and steadily within the tunnels. Whether in narrow tunnels, sloping mining passages, or other complex underground terrains, tracks 6 provide sufficient traction and mobility, allowing the drilling rig to flexibly relocate to different work sites. This reduces movement difficulties and equipment downtime caused by poor road conditions, improves equipment mobility and operational range, and ensures the continuity of construction.

[0075] The mobility of the tracked 6 allows the multi-functional roof-cutting drilling rig to be more flexible in its construction layout. It can quickly adjust its working position according to the actual mining progress and construction needs, enabling roof cutting and anchor bolt support in different areas. For example, during the advancement of a fully mechanized mining face, as the coal mining machine moves forward, the drilling rig can use the tracked 6 to keep up and carry out construction on newly exposed roof sections in sequence, without waiting for complex hoisting or other transfer equipment. This optimizes the time arrangement of the entire construction process, increases the mining speed of underground engineering, reduces construction costs, and improves equipment utilization efficiency.

[0076] Furthermore, it also includes lifting support columns 8, which are installed on the frame 1. There are several lifting support columns 8, located on both sides of the track 6, and guardrails 9 are installed on the lifting platform 2.

[0077] In this embodiment, the lifting supports 8 are mounted on the frame 1 and located on both sides of the tracks 6. The presence of multiple lifting supports 8 provides additional support for the entire drilling rig. In underground engineering construction, especially under complex geological conditions or during high-load operations, the drilling rig requires more stable support to ensure construction safety and normal equipment operation. The lifting supports 8 can be height-adjusted according to the actual ground conditions, ensuring close contact with the ground, sharing some of the weight borne by the tracks 6, increasing the overall ground contact area of ​​the drilling rig, thereby improving the stability of the drilling rig on different terrains, preventing tilting, swaying, or even tipping over due to unstable center of gravity, soft ground, etc., and ensuring that operations such as roof cutting and anchor bolt support can be carried out smoothly.

[0078] The lifting strut 8 and the tracks 6 work together to further enhance the drilling rig's adaptability to diverse terrains. The tracks 6 are primarily responsible for the movement of the drilling rig, while the lifting strut 8 plays a crucial auxiliary support role when the drilling rig is not in operation. When the drilling rig travels to sloping roadways, uneven ground, or areas with geological subsidence, the tracks 6 can move using their excellent grip. After reaching the designated working position, the lifting strut 8 can adjust its height according to the terrain's elevation differences, keeping the drilling rig level and stable. Whether in inclined mining area passages or undulating tunnels, it provides a stable and reliable platform for construction, allowing the roof-cutting drilling rig 3 and the bolting drilling rig 4 to carry out precise operations, thus improving the equipment's adaptability to complex underground environments.

[0079] The guardrail 9 is installed on the lifting platform 2, providing crucial safety protection for construction personnel operating the control console 5 and performing other related tasks on the lifting platform 2. In underground construction projects, the lifting platform 2 is typically raised and lowered according to construction needs. Construction personnel are at a relatively high position, posing a risk of falling from the platform edge due to accidental slips, equipment swaying, or other reasons. The guardrail 9 forms an effective barrier, preventing accidental falls and confining the workers' movement to a relatively safe area. This significantly reduces the probability of falls from heights, ensuring the personal safety of construction personnel and meeting the stringent safety requirements for personnel protection in underground construction projects.

[0080] Furthermore, it also includes an abutment seat 10, which is slidably disposed relative to the first guide rail 302. The abutment seat 10 is used to abut against the top wall when the top cutting drill 3 is working.

[0081] In this embodiment, the abutment seat 10 is slidably disposed relative to the first guide rail 302 and abuts against the top wall when the top-cutting drill 3 is working. This design provides an additional support point for the top-cutting drill 3, effectively enhancing the stability during the drilling process. During top-cutting operations, the power head of the drill drives the drill bit to rotate and drill into the top plate, generating a large reaction force, which can easily cause the drill to shake, thus affecting the drilling accuracy and straightness. However, after the abutment seat 10 is tightly abutted against the top wall, it can withstand a portion of the reaction force and transfer it to the top wall, thereby reducing the shaking amplitude of the drill and ensuring that the drill bit always moves along the predetermined direction and angle during drilling, improving the stability of the drilling, ensuring the accuracy of the top-cutting drill, and making the drilled hole more in line with the construction design requirements, laying a good foundation for the subsequent effective cutting and collapse control of the top plate.

[0082] The contact between the abutment seat 10 and the top wall also serves as an auxiliary positioning feature, further improving the accuracy of the roof cutting operation. Since the abutment seat 10 is slidably positioned relative to the first guide rail 302, it can move along the guide rail as the borehole advances, maintaining constant contact with the top wall. This helps operators more accurately grasp the depth and angle of the borehole. In actual construction, operators can observe the position of the abutment seat 10 and its contact with the top wall to adjust the drilling parameters of the roof cutting drill rig 3 in a timely manner, ensuring that the position, depth, and angle of each borehole are optimal. This improves the adaptability of the roof cutting operation to complex roof conditions, ensures the accuracy and scientific nature of the entire roof cutting work, facilitates effective control of roof collapse, and ensures the safety and stability of the underground mining space.

[0083] The sliding characteristic of the abutment seat 10 relative to the first guide rail 302 allows it to adapt well to roof walls of different shapes and undulations. In underground engineering, the surface of the roof slab is not always flat; there may be local unevenness, inclination, or curvature. The abutment seat 10 can automatically adjust its contact position and fit with the roof wall by sliding according to the actual shape of the roof wall, always maintaining a tight fit. This ensures that it can provide effective support and positioning for the roof cutting drill 3 regardless of the condition of the roof slab. This adaptability to different roof wall conditions greatly expands the applicability of the roof cutting drill 3, enabling it to operate smoothly in various complex roof environments, improving the equipment's ability to cope with complex geological conditions, and ensuring the continuity and effectiveness of construction.

[0084] The sliding arrangement of the abutment seat 10 allows the force on the top-cutting drill 3 to be more evenly distributed across the entire drill structure when interacting with the top wall. When the abutment seat 10 abuts against the top wall and bears the reaction force, it can slide along the first guide rail 302 to reasonably transfer the force to other components of the drill and the entire support structure of the drill rig, avoiding stress concentration in one place that could lead to component damage or deformation. This even force distribution helps extend the service life of the equipment, reduce equipment failures caused by excessive local stress, ensure the stable and reliable operation of the top-cutting drill 3 during long-term, high-intensity construction, reduce equipment maintenance costs and replacement frequency, and improve the overall durability and economy of the equipment.

[0085] Furthermore, the first guide rail 302 has a mounting part and also includes a first linear drive 11. The first linear drive 11 is disposed on the mounting part and is used to drive the abutment seat 10 to abut against the top wall. The first rotation drive 12 rotates relative to the lifting platform 2 and is raised and lowered. The first mounting seat 301 is disposed on the output end of the first rotation drive 12. The second rotation drive 13 is disposed on the lifting platform 2. The second mounting seat 401 is disposed on the output end of the second rotation drive 13.

[0086] In this embodiment, the first linear drive 11 is mounted on the mounting part of the first guide rail 302 to drive the abutment seat 10 to abut against the top wall. This design enables precise control of the abutment process. During roof cutting operations, different roof conditions, drilling depths, and drilling rig operating states all require the abutment seat 10 to abut against the top wall with appropriate force and position to achieve optimal support and stability. The first linear drive 11 can precisely adjust the moving distance and abutment pressure of the abutment seat 10 according to the actual situation, ensuring close and stable contact with the top wall and effectively reducing the shaking of the roof cutting drill 3 during drilling. For example, when the roof rock has high hardness and requires a larger abutment force, the first linear drive 11 can increase the driving force, allowing the abutment seat 10 to better withstand the reaction force, ensuring the smooth drilling process of the drill bit, improving drilling accuracy, and laying the foundation for the smooth progress of subsequent roof cutting work.

[0087] Moreover, precise drive control can prevent the abutment seat 10 from causing unnecessary damage to the top wall due to excessive contact, while also preventing insufficient contact from failing to fully exert its stabilizing effect, thus extending the service life of the equipment, optimizing the interaction between the equipment and the top plate, and improving the overall quality and efficiency of the roof cutting operation.

[0088] As the drilling work of the top-cutting drill rig 3 progresses, the first linear drive component 11 can dynamically adjust the position of the abutment seat 10 to ensure effective contact with the roof. During drilling, the condition of the roof may change, such as encountering rock fissures or changes in hardness. The abutment seat 10 needs to adjust its contact state in real time to adapt to these changes. Through real-time monitoring and feedback, the first linear drive component 11 flexibly changes the position and contact force of the abutment seat 10, ensuring that the top-cutting drill rig 3 can maintain a stable working state regardless of changes in roof conditions. This guarantees the continuity of drilling operations, reduces construction interruptions or decreased drilling quality caused by roof changes, improves the equipment's adaptability to complex geological conditions, and ensures the smooth progress of construction.

[0089] The first rotary drive component 12 is mounted on the lifting platform 2, and the first mounting base 301 is mounted on its output end, greatly facilitating the adjustment of the drilling angle of the top-cutting drill 3. In underground engineering construction, facing roofs with different orientations and inclination angles, it is necessary to quickly and accurately adjust the drilling angle of the top-cutting drill 3 to ensure that the borehole effectively matches the roof according to design requirements, achieving precise top cutting. Driven by the first rotary drive component 12, operators only need to perform corresponding operations on the control panel to easily rotate the first mounting base 301 to the appropriate angle, eliminating the need for laborious manual adjustment of the equipment angle. This simplifies the operation process, improves the efficiency of angle adjustment, and enables the top-cutting drill 3 to quickly adapt to different roof conditions, meeting diverse construction needs.

[0090] Similarly, the second rotary drive component 13 is mounted on the lifting platform 2 and connected to the second mounting base 401, providing the same convenient operation method for adjusting the anchor bolt construction angle of the anchor bolt drilling rig 4. In tunnel support operations, the angle of the anchor bolt drilling rig 4 can be quickly changed according to the requirements of different parts (such as the roof, sidewalls, etc.) and different geological structures, accurately driving the anchor bolt into the predetermined position, ensuring the anchor bolt support effect, optimizing the operational convenience of anchor bolt construction, and improving the efficiency of the entire support operation.

[0091] The first rotary drive component 12 and the second rotary drive component 13 enable precise control of the angles of the roof-cutting drill 3 and the anchor bolt drill 4. During construction, accurate angles are crucial for the quality of roof cutting and anchor bolt installation; even slight angular deviations can lead to uneven roof cutting and poor anchor bolt anchoring. These two rotary drive components are typically equipped with high-precision angle sensors and control systems. Operators can precisely set and adjust the drill rig angles according to the construction design requirements, with errors controlled within a minimal range. This ensures that the construction angle of each borehole and each anchor bolt meets standards, improving construction accuracy, guaranteeing the quality of roof control and support in underground engineering, and creating a safe and stable environment for subsequent mining operations.

[0092] Furthermore, the lifting platform 2 includes a support platform 201, which is raised and lowered relative to the frame 1. A second linear drive 14 is disposed on the support platform 201. A lifting platform 15 is disposed on the output end of the second linear drive 14 and is raised and lowered relative to the support platform 201. A first rotary drive 12 is disposed on the lifting platform 15, and the second linear drive 14 is used to drive the lifting platform 15 to rise and fall.

[0093] In this embodiment, the lifting platform 2 adopts a double-layer lifting structure of support platform 201 and lifting platform 15, which greatly expands the adjustment range of the working height. In underground engineering construction, the distance between the roof and the ground varies greatly in different roadways and different mining stages, resulting in different requirements for the working height of the roof-cutting drilling rig 3 and the anchor drilling rig 4. By lifting the support platform 201 relative to the frame 1 and then lifting the lifting platform 15 relative to the support platform 201, a more precise and wide range of height adjustments can be achieved, ensuring that the drilling rig can accurately reach the roof position at different heights for operation. Whether it is a high, large-section roadway or a relatively low mining area passage, the construction height requirements can be met, enhancing the adaptability of the drilling rig to complex underground space height changes and ensuring the smooth progress of construction.

[0094] This double-layer lifting structure facilitates precise positioning of the height for roof cutting and anchor bolt installation, thereby optimizing construction accuracy. In actual operation, operators can control the lifting of the support platform 201 and the lifting frame 15 based on pre-measured roof height data and construction design requirements, precisely adjusting the drilling rig to the optimal working height. This ensures that key construction parameters such as the depth of the roof cutting borehole and the angle of anchor bolt insertion meet standards more accurately, improving construction precision and quality. For example, during anchor bolt support, precise height positioning ensures that the anchor bolts are driven into the rock mass at the appropriate angle and depth, fully utilizing their anchoring effect, ensuring the stability of the tunnel roof and sidewalls, and creating a safe and reliable environment for subsequent mining operations.

[0095] The step-by-step lifting adjustment of the support platform 201 and the lifting platform 15 simplifies operation and improves convenience. Compared to a single, large-range lifting structure, the double-layer lifting structure breaks down a large height adjustment range into two relatively smaller, more controllable adjustment steps. Operators at the control console can more intuitively and accurately control the lifting amplitude at each stage, avoiding operational errors or difficulty in precise positioning due to excessively large adjustments at once. This reduces the skill requirements for operators, allowing personnel of varying experience levels to easily master the operation, improving equipment operability and making the construction process smoother and more efficient.

[0096] Typically, the lifting operations of the support platform 201 and the lifting platform 15 can be integrated into the control console 5 for centralized control, which further improves operational efficiency. Operators no longer need to switch between different control points; on the unified operating interface of the control console 5, they can easily coordinate and control the lifting of both, quickly adjusting the appropriate working height according to construction needs. Furthermore, by combining the control of other components such as the first rotary drive component 12, they can achieve coordinated adjustment of multiple parameters such as the angle and height of the top-cutting drilling rig 3 and the anchor bolt drilling rig 4, optimizing the operational convenience of the entire construction process. This makes the connection between the top-cutting and anchor bolt support operations closer and more efficient, improving the overall construction efficiency.

[0097] Furthermore, it also includes an auxiliary support 16, which is swayed on the support platform 201. The auxiliary support 16 has a support end, which is hinged to the lifting platform 15.

[0098] In this embodiment, the auxiliary support 16 is swaying on the support platform 201, and its supporting end is hinged to the lifting platform 15. When the lifting platform 15 is raised and lowered, or when it is carrying equipment such as the top-cutting drill 3 and the anchor drill 4, the auxiliary support 16 can provide additional support force. When the lifting platform 15 is at different heights, especially when it is raised to a higher position or when it is carrying a heavy equipment load, the auxiliary support 16 can adjust its own angle by swaying to support the lifting platform 15 in a suitable posture, sharing part of the equipment weight and the external forces generated during operation, such as the reaction force of the top-cutting drill 3 when drilling. This enhances the structural stability of the entire lifting platform 2 and even the entire drilling rig, reduces the risk of structural deformation or shaking caused by concentrated force, ensures the smooth operation of the equipment during construction, and improves the safety and reliability of construction.

[0099] Because the auxiliary support component 16 is oscillating, it can flexibly change its support angle according to different lifting heights of the lifting platform 15, different equipment layouts, and the direction of force during operation, achieving effective support from multiple angles. In underground engineering construction, the working conditions are complex and varied. For example, changes in the slope of the tunnel and different inclination angles of the roof will affect the stress state of the lifting platform 15. The auxiliary support component 16 can adapt to these changes through its own oscillation, always providing support for the lifting platform 15 that meets the actual needs. This enhances the adaptability of the entire drilling rig to complex working conditions, enabling it to maintain a stable operating state in various underground environments and ensuring the smooth progress of construction.

[0100] Furthermore, the auxiliary support component 16 is a hydraulic cylinder.

[0101] In this embodiment, the auxiliary support 16 adopts a hydraulic cylinder structure, which enables precise adjustment of the support force. The additional support force required by the lifting platform 15 varies in different construction scenarios. For example, when cutting hard roof rock, the reaction force generated by the cutting drill 3 is large, requiring the auxiliary support 16 to provide stronger support to maintain the stability of the lifting platform 15. Conversely, during conventional anchor bolt support operations, the required support force is relatively small. The hydraulic cylinder can precisely control the oil pressure through the hydraulic system, thereby accurately adjusting the output support force to perfectly match the actual working conditions. This ensures that the lifting platform 15 remains stable at all times, avoiding insufficient or excessive support force that could affect equipment operation and construction quality, and improving the overall adaptability of the drilling rig to complex working conditions.
