Description

Technical Field

[0001] This utility model relates to the field of ore mining technology, and in particular to a geological drilling device for mining. Background Technology

[0002] Ore mining is a key process for extracting valuable mineral resources from the earth's crust, encompassing two main methods: open-pit and underground mining. Open-pit mining is suitable for shallowly buried ore bodies with large reserves, directly extracting ore by stripping away the surface covering material, and is characterized by low cost and high efficiency. Underground mining, on the other hand, is for deeply buried ore bodies, entering the ore body through channels such as vertical shafts and inclined shafts, and using techniques such as room-and-pillar mining, caving mining, or backfilling mining. It is crucial to address challenges such as ground pressure management, ventilation, and drainage.

[0003] In the process of ore mining, it is necessary to drill holes of a specified depth and diameter into the rock strata to place explosives. The rocks are then broken by blasting to achieve ore mining or stone excavation operations. A search revealed a utility model patent with Chinese patent number CN221590885U, which discloses a mining drilling machine. Compared with the prior art, this utility model patent with Chinese patent number CN221590885U uses a rack and pinion mechanism to move, which drives the gear to rotate, thereby driving the shaft to rotate, which in turn drives the motor to rotate. The tilt angle of the motor can be changed to drill holes at different angles. No manual support is required, which is beneficial to the convenience of operation.

[0004] However, in actual use, the depth of the drilling of the above-mentioned device is limited and it is impossible to drill holes of a suitable depth according to the actual mining needs. Therefore, in order to solve the above problems, a geological drilling equipment for mining is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a geological drilling device for mining operations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A geological drilling equipment for mining includes a mobile vehicle body, on which a lifting mechanism is provided. The lifting mechanism includes a first slide rail arranged symmetrically, a second slide rail slidably arranged on the inner side of the first slide rail, a sliding drill platform slidably arranged between the two second slide rails, and a drill bit rotatably arranged on the sliding drill platform. Both of the first slide rails are provided with a pipe changing mechanism on their sides. The pipe changing mechanism includes a rotating disk on which multiple drill pipe bodies are movably mounted. A replacement slide rail is fixedly installed between the two first slide rails. A threaded slide is slidably provided on the inner side of the replacement slide rail. A retractable hydraulic clamp is installed on the threaded slide. The hydraulic clamp is used to clamp the drill pipe body and install it on the drill bit.

[0007] The above technical solution further includes: The lifting mechanism also includes a fixing plate, which is installed on the side of the two first slide rails near the main body of the mobile vehicle. The top of the first slide rails is symmetrically fixedly connected to a first hydraulic cylinder. The telescopic end of the first hydraulic cylinder is rotatably connected to a first double sprocket. A first double chain is sleeved on the first double sprocket. The two ends of the first double chain are fixedly connected to the main body of the mobile vehicle and the mounting plate respectively through a first connecting end plate. The mounting plate is fixedly connected between the two second slide rails.

[0008] A second hydraulic cylinder is symmetrically fixedly connected to the mounting plate. The telescopic end of the second hydraulic cylinder is rotatably connected to a second double sprocket. A second double chain is sleeved on the second double sprocket. The two ends of the second double chain are fixedly connected to the sliding drill table and the mounting plate respectively through a second connecting end plate.

[0009] The sliding drill rig is fixedly equipped with a drilling motor. The output end of the drilling motor is fixedly connected to a rotating connector. The end of the rotating connector away from the drilling motor has a threaded groove. The end of the drill bit near the rotating connector is fixedly connected to a threaded protrusion. The threaded protrusion and the threaded groove are threadedly connected.

[0010] The tube replacement mechanism also includes a connecting support plate installed on the side of the first slide rail away from the second slide rail. The two connecting support plates are fixedly connected to the replacement slide rail. A replacement motor is fixedly installed at one end of the replacement slide rail. A replacement threaded rod that is rotatably connected to the output end of the replacement motor is fixedly connected to the replacement slide rail. A threaded slide table that slides relative to the replacement slide rail is threadedly connected to the replacement threaded rod.

[0011] A clamping hydraulic cylinder is installed on one side of the threaded slide, and the clamping hydraulic cylinder is fixedly connected to the hydraulic clamp.

[0012] A drill rod platform is symmetrically fixedly connected to the side of the first slide rail near the connecting support plate. A rod changing motor is fixedly installed on the top of the drill rod platform. The rotating disk is rotatably connected to the opposite side of the two drill rod platforms. A rotating shaft that is connected to the output end of the rod changing motor is fixedly connected between the two rotating disks. An electromagnetic fixing semi-ring cylinder is circumferentially installed on the opposite side of each rotating disk. The drill rod body is placed between the two vertical electromagnetic fixing semi-ring cylinders.

[0013] The top of the drill rod body is provided with a hexagonal groove, and a limiting head is fixedly connected in the hexagonal groove. A connecting threaded ring is fixedly connected to the bottom of the drill rod body. The limiting head and the threaded groove do not contact each other, and the connecting threaded ring and the threaded protrusion can be threadedly connected.

[0014] This utility model has the following beneficial effects: In this invention, the lifting mechanism adopts a staged drive method using a first hydraulic cylinder and a second hydraulic cylinder. The first hydraulic cylinder drives the mounting plate and the second slide rail to move up and down through a first double sprocket and a first double chain, achieving a wide range of overall lifting and adjustment. The second hydraulic cylinder drives the sliding drill platform to move up and down further on the second slide rail through a second double sprocket and a second double chain. This multi-stage drive structure makes the drill bit move more flexibly in the vertical direction, meeting the drilling needs of different depths.

[0015] In this invention, the drill pipe changing mechanism automates drill pipe replacement, significantly improving the continuity and efficiency of drilling operations. The replacement motor drives the threaded rod to rotate, causing the threaded slide to slide on the replacement rail. Driven by the clamping hydraulic cylinder, the hydraulic clamp accurately holds the drill pipe body and installs it onto or removes it from the drill bit. The entire process requires no manual operation, reducing replacement time and lowering the labor intensity for workers. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-9 As shown, the present invention proposes a geological drilling equipment for mining, including a mobile vehicle body 1, a lifting mechanism on the mobile vehicle body 1, the lifting mechanism including a first slide rail 4 symmetrically arranged, a second slide rail 40 slidably arranged on the inner side of the first slide rail 4, a sliding drill platform 2 slidably arranged between the two second slide rails 40, and a drill bit 22 rotatably arranged on the sliding drill platform 2. Both sides of the first slide rails 4 are provided with a pipe changing mechanism. The pipe changing mechanism includes a rotating disk 31, on which multiple drill rod bodies 33 are movably mounted. A replacement slide rail 5 is fixedly installed between the two first slide rails 4. A threaded slide table 53 is slidably provided on the inner side of the replacement slide rail 5. A retractable hydraulic clamp 55 is installed on the threaded slide table 53. The hydraulic clamp 55 is used to clamp the drill rod body 33 and install it on the drill bit 22. Furthermore, during the actual drilling process, due to different actual production needs, it is necessary to install a drill rod body 33 on the drill bit 22 to increase the drilling depth. During the drilling process, the first hydraulic cylinder 42 and the second hydraulic cylinder 47 are used to achieve staged lifting. After being lifted to a certain height, the drill rod body 33 is installed on the drill bit 22. The first hydraulic cylinder 42 and the second hydraulic cylinder 47 are used to move the drill bit 22 downward, while the drill bit 22 rotates to drill. Furthermore, after the drill rod body 33 is fully inserted into the hole, the connection between the drill rod body 33 and the drilling motor 20 is disconnected. Then, the first hydraulic cylinder 42 and the second hydraulic cylinder 47 are activated, driving the drilling motor 20 to rise. Subsequently, another drill rod body 33 is installed at the output end of the drilling motor 20.

[0020] like Figures 3-4 As shown, the lifting mechanism also includes a fixing plate 41, which is installed on the side of the two first slide rails 4 near the mobile vehicle body 1. The top of the first slide rails 4 is symmetrically fixedly connected to a first hydraulic cylinder 42. The telescopic end of the first hydraulic cylinder 42 is rotatably connected to a first double sprocket 43. A first double chain 44 is sleeved on the first double sprocket 43. The two ends of the first double chain 44 are fixedly connected to the mobile vehicle body 1 and the mounting plate 46 respectively through a first connecting end plate 45. The mounting plate 46 is fixedly connected between the two second slide rails 40. A second hydraulic cylinder 47 is symmetrically fixedly connected to the mounting slide plate 46. A second double sprocket 48 is rotatably connected to the telescopic end of the second hydraulic cylinder 47. A second double chain 49 is sleeved on the second double sprocket 48. The two ends of the second double chain 49 are fixedly connected to the sliding drill table 2 and the mounting slide plate 46 respectively through the second connecting end plate 410. Furthermore, when downward drilling or raising the drilling motor 20 is required, a tiered lifting mechanism can be used. The first-stage lifting involves activating the first hydraulic cylinder 42, symmetrically fixed to the top of the first slide rail 4. The telescopic end of the first hydraulic cylinder 42 extends, driving the first double sprocket 43, which is rotatably connected to it, to move. Since the first double sprocket 43 is fitted with a first double chain 44, and both ends of the first double chain 44 are fixedly connected to the mobile vehicle body 1 and the mounting slide plate 46 respectively via the first connecting end plate 45, the movement of the first double sprocket 43 causes the first double chain 44 to roll on it. As the first double chain 44 rolls, the mounting slide plate 46 experiences an upward pulling force, thereby causing the two second slide rails 40 to slide inside the first slide rail 4, thus raising the overall height of the drilling motor 20 to adapt to drilling operations at different heights.

[0021] Furthermore, in the secondary lifting stage: the extension end of the second hydraulic cylinder 47, which is symmetrically fixed on the mounting plate 46, moves, causing the rotating second double sprocket 48 to move. Since the two ends of the second double chain 49 are connected to the sliding drill platform 2 and the mounting plate 46 through the second connecting end plate 410, the movement of the second double sprocket 48 causes the second double chain 49 to roll, which in turn causes the sliding drill platform 2 to slide on the second slide rail 40, thus achieving secondary lifting and increasing the adjustable range of the overall height of the drilling motor 20.

[0022] like Figures 6-9As shown, a drilling motor 20 is fixedly installed on the sliding drill table 2. A rotating connector 21 is fixedly connected to the output end of the drilling motor 20. A threaded groove 210 is provided at the end of the rotating connector 21 away from the drilling motor 20. A threaded protrusion 220 is fixedly connected to the end of the drill bit 22 near the rotating connector 21. The threaded protrusion 220 and the threaded groove 210 are threadedly connected. The top of the drill rod body 33 is provided with a hexagonal groove 330, and a limiting head 331 is fixedly connected in the hexagonal groove 330. A connecting threaded ring 332 is fixedly connected to the bottom of the drill rod body 33. The limiting head 331 does not contact the threaded groove 210, and the connecting threaded ring 332 and the threaded protrusion 220 can be threadedly connected. Furthermore, before preparing to carry out mining geological drilling operations, the drill bit 22 is installed on the rotating connector 21. When preparing to carry out mining geological drilling operations, the drill bit 22 needs to be removed first, and then the drilling motor 20 is raised to a certain height, and the drill rod body 33 is installed between the drill bit 22 and the rotating connector 21. Furthermore, the opening size of the threaded groove 210 is larger than the size of the limiting head 331. The limiting head 331 is provided with threads on its outer side. The limiting head 331 can be threadedly connected to the connecting threaded ring 332. Therefore, multiple drill rod bodies 33 can be threadedly connected end to end to be assembled into one unit.

[0023] Furthermore, the top of the drill rod body 33 is provided with a hexagonal groove 330, and the end of the rotating connector 21 is fixedly connected to a hexagonal boss, and a threaded groove 210 is provided at its center. The hexagonal groove 330 and the hexagonal boss engage with each other, and the connecting threaded ring 332 at the bottom of the drill rod body 33 and the threaded protrusion 220 can be threadedly connected. When the drill rod body 33 is placed between the rotating connector 21 and the drill bit 22, the hexagonal groove 330 and the hexagonal boss are limited. Therefore, when the drilling motor 20 drives the rotating connector 21 to rotate, it will also drive the drill rod body 33 to rotate. At this time, through the rotation of the drill rod body 33, the connecting threaded ring 332 and the threaded protrusion 220 are threadedly connected into a whole, and finally drive the drill bit 22 to rotate to perform drilling operations.

[0024] like Figure 5 As shown, the tube changing mechanism also includes a connecting support plate 50 installed on the side of the first slide rail 4 away from the second slide rail 40. The two connecting support plates 50 are fixedly connected to the changing slide rail 5. A changing motor 51 is fixedly installed at one end of the changing slide rail 5. A changing threaded rod 52 that is rotatably connected to the output end of the changing motor 51 is fixedly connected to the changing slide rail 5. A threaded slide table 53 that slides relative to the changing slide rail 5 is threadedly connected to the changing threaded rod 52. A clamping hydraulic cylinder 54 is installed on one side of the threaded slide table 53, and the clamping hydraulic cylinder 54 is fixedly connected to the hydraulic clamp 55. The first slide rail 4 is symmetrically fixedly connected to the drill rod platform 3 on the side near the connecting support plate 50. The top drill rod platform 3 is fixedly installed with a rod changing motor 30. The rotating disk 31 is rotatably connected to the opposite side of the two drill rod platforms 3. The rotating shaft 32, which is connected to the output end of the rod changing motor 30, is fixedly connected between the two rotating disks 31. The opposite side of the rotating disk 31 is circumferentially installed with an electromagnetic fixing semi-ring cylinder 34. The drill rod body 33 is placed between the two vertical electromagnetic fixing semi-ring cylinders 34. Furthermore, before the equipment is ready to perform the pipe replacement operation, multiple drill rod bodies 33 are placed between electromagnetic fixing semi-ring cylinders 34 on opposite sides of the two rotating disks 31 in the vertical direction. When the electromagnetic fixing semi-ring cylinders 34 are energized, they will generate magnetic force to firmly fix the drill rod bodies 33, preventing them from shaking or falling during equipment operation and ensuring the stable placement of the drill rods. Furthermore, when it is necessary to replace the drill rod, the rod changing motor 30 fixedly installed on the top drill rod platform 3 is started. Its output end drives the rotating shaft 32 connected to it to rotate. The rotation of the rotating shaft 32 will synchronously drive the two rotating disks 31 to rotate together. As the rotating disks 31 rotate, the multiple drill rod bodies 33 placed between the electromagnetic fixed semi-ring cylinders 34 will also rotate. The operator can rotate the drill rod body 33 of the appropriate specification to a position that is easy to clamp according to actual needs. Furthermore, after starting the replacement motor 51 and moving the threaded slide 53 to the vicinity of the target drill rod body 33, the clamping hydraulic cylinder 54 installed on one side of the threaded slide 53 begins to work. The telescopic end of the clamping hydraulic cylinder 54 extends, pushing the hydraulic clamp 55 fixedly connected to it closer to the drill rod body 33. The hydraulic clamp 55 has sufficient clamping force, and when it contacts the drill rod body 33, it can tightly clamp the drill rod body 33, ensuring that the drill rod will not fall off during subsequent movement and installation.

[0025] Furthermore, after the hydraulic clamp 55 clamps the drill pipe body 33, the replacement motor 51 is restarted, causing it to rotate in the opposite direction. The replacement threaded rod 52 also rotates in the opposite direction, driving the threaded slide table 53 to move along the replacement slide rail 5 towards the drill bit 22. When the drill pipe body 33 is moved near the drill bit 22, the drill pipe body 33 is connected to the drill bit 22 in the manner described above. Thus, one drill pipe replacement operation is completed.

[0026] Furthermore, if it is necessary to disassemble the already installed drill rod body 33, the operation process is the reverse of the installation process. First, fix the drill bit 22, then start the drilling motor 20 in reverse to disconnect the threaded connection between the drill rod body 33 and the drill bit 22. At this time, the drill rod body 33 is in a free state. The drill rod body 33 is clamped by controlling the hydraulic clamp 55. Then, start the replacement motor 51 to make the threaded slide 53 move the drill rod body 33 away from the drill bit 22. Then disconnect the connection between the drill rod body 33 and the drill bit 22. Finally, put the drill rod body 33 back into the original electromagnetic fixing semi-ring cylinder 34 for fixed storage.

[0027] In this embodiment, the cooperation between the lifting mechanism and the pipe-changing mechanism can be completed under the system control of the mobile vehicle body 1, and multiple sensors are installed between the lifting mechanism and the pipe-changing mechanism to ensure the smooth completion of various actions.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
