Description

Technical Field

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

[0002] In the field of geological exploration, an accurate understanding of underground geological structures is crucial for various engineering projects. Whether it is the site selection for the foundation of large-scale building projects or the planning and design of roads and bridges, precise geological data is indispensable. As the core equipment for obtaining deep underground geological information, the performance of advanced drilling equipment directly affects the accuracy of exploration results and work efficiency. In actual exploration, different geological conditions require different types of drill bits. From hard rock strata to soft soil layers, the degree of drill bit wear varies significantly. This requires advanced drilling equipment to have the function of convenient drill bit replacement. Quick and efficient drill bit replacement can reduce equipment downtime, improve the continuity of exploration operations, and reduce exploration costs, which is of great significance for promoting the development of the geological exploration industry.

[0003] Existing geological exploration advanced drilling equipment typically uses a traditional threaded connection method for drill bit connection, where the drill bit is directly screwed onto the drill rod via threads. This method utilizes the meshing of the threads to transmit torque and axial force, and relies on the friction between the threads to maintain the stability of the connection.

[0004] However, existing technologies have limitations in conveniently disassembling and replacing drill bits. In actual geological exploration operations, geological conditions are complex and variable, and drill bits experience severe wear. For advanced drilling devices with threaded connections, the threads are prone to seizing or rusting due to high torque, vibration, and corrosion from the soil and rock during drilling. When drill bits need to be replaced, workers often have to spend a lot of time and effort using wrenches and other tools to painstakingly unscrew the drill bit from the drill rod, which affects the efficiency of drill bit replacement and increases equipment downtime. Therefore, an advanced drilling device for geological exploration is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a geological exploration advanced drilling device, which aims to improve the problem in the prior art that when it is necessary to change the drill bit, workers often need to spend a lot of time and effort, and use tools such as wrenches, to unscrew the drill bit from the drill rod with difficulty.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A geological exploration advanced drilling device includes a drilling rig, a lifting platform is provided on the top of the drilling rig, a support base is provided on one side of the lifting platform, a motor is fixedly connected to the top of the support base, a hollow column is fixedly connected to the output end of the motor, a limit frame is fixedly connected to one side of the drilling rig, a cleaning component is provided inside the limit frame, and a connecting component is provided inside the hollow column.

[0008] The connecting assembly includes a connecting post, which is slidably connected inside the hollow post. A drill bit is fixedly connected to the bottom end of the connecting post, and a clamping plate is fixedly connected to the top end of the connecting post. A first clamping block and a second clamping block are slidably connected inside the hollow post. A bidirectional screw is threaded inside both the first and second clamping blocks. Both the first and second clamping blocks are fitted into the clamping plate, and knobs are fixedly connected to both ends of the bidirectional screw.

[0009] As a further description of the above technical solution:

[0010] The cleaning component includes a support plate and a support column. The limiting frame is fixedly connected to the outer wall of the support plate, and the bottom end of the support column is fixedly connected to the top end of the support plate.

[0011] As a further description of the above technical solution:

[0012] A ring-shaped water pipe is fixedly connected to the top of the support column, and a water injection pipe is provided on the outer wall of the ring-shaped water pipe.

[0013] As a further description of the above technical solution:

[0014] The annular water pipe is equipped with multiple nozzles, which are evenly distributed in a ring array inside the annular water pipe.

[0015] As a further description of the above technical solution:

[0016] A support frame is fixedly connected inside the support plate, and a collar is provided inside the support frame.

[0017] As a further description of the above technical solution:

[0018] A cleaning brush is installed inside the collar, and a telescopic column is fixedly connected inside the support frame.

[0019] As a further description of the above technical solution:

[0020] One end of the telescopic column is fixedly connected to a support block, which is shaped like a frustum and is engaged with the side wall of the collar.

[0021] As a further description of the above technical solution:

[0022] The telescopic column is fitted with a spring on its outer wall, and the two ends of the spring are fixedly connected to the inside of the support frame and the support block, respectively.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by rotating the knob, the bidirectional screw is driven to rotate, causing the first and second locking blocks to move inside the hollow column and engage with the locking plate, thus stabilizing the connecting column and fixing the drill bit. When disassembling, rotating the knob in the opposite direction releases the locking blocks and the locking plate, allowing the connecting column and the drill bit to be removed. This achieves the effect of convenient disassembly and replacement of the drill bit, solving the problem that when it is necessary to replace the drill bit, workers often need to spend a lot of time and effort, using tools such as wrenches, to unscrew the drill bit from the drill rod with difficulty, thereby improving the flexibility of the advance drilling device.

[0025] 2. In this utility model, the drill bit is driven by a lifting platform to pass through the limiting frame and enter the ground. Water is injected into the annular water pipe through the water injection pipe, and the water is sprayed out from the nozzle to rinse the area around the drill bit, remove drill cuttings and cool the drill bit. The cleaning brush inside the collar contacts the drill bit and brushes away the attached drill cuttings and other impurities, achieving efficient cooling and cleaning of the drill bit. This solves the problem that in traditional advanced drilling devices, the drill bit lacks effective cooling and cleaning measures during the drilling process, resulting in accelerated wear, shortened service life, and drill cuttings accumulation affecting drilling accuracy and efficiency. This improves the practicality of the advanced drilling device. Attached Figure Description

[0035] The connecting assembly includes a connecting post 6, which is slidably connected inside the hollow post 5 to ensure the precise positioning and stable operation of the drill bit 7. The drill bit 7 is fixedly connected to the bottom end of the connecting post 6, and a clamping plate 12 is fixedly connected to the top end of the connecting post 6 to ensure that the connecting post 6 remains stable during drilling. A first clamping block 8 and a second clamping block 9 are slidably connected inside the hollow post 5. A bidirectional screw 10 is threaded inside the first clamping block 8 and the second clamping block 9. Both the first clamping block 8 and the second clamping block 9 are engaged with the clamping plate 12. By rotating the knob 11, the bidirectional screw 10 can be rotated, thereby driving the first clamping block 8 and the second clamping block 9 to move along the inside of the hollow post 5. When these two clamping blocks are engaged with the clamping plate 12, they are then used to securely fix the drill bit 7 through the connecting post 6. A knob 11 is fixedly connected to both ends of the bidirectional screw 10.

[0036] Reference Figure 1 , Figure 4 and Figure 5The cleaning component includes a support plate 14 and a support column 15. A limiting frame 13 is fixedly connected to the outer wall of the support plate 14. The bottom end of the support column 15 is fixedly connected to the top end of the support plate 14. An annular water pipe 16 is fixedly connected to the top end of the support column 15. A water injection pipe 17 is provided on the outer wall of the annular water pipe 16. Multiple nozzles 18 are provided inside the annular water pipe 16. The function of the annular water pipe 16 and the nozzles 18 is to provide sufficient cooling water flow to prevent the drill bit 7 from overheating at high temperatures, and at the same time to provide a cleaning effect for the drill bit 7. The multiple nozzles 18 are evenly distributed in a ring array inside the annular water pipe 16.

[0037] A support frame 19 is fixedly connected inside the support plate 14. A collar 20 is installed inside the support frame 19, and a cleaning brush 24 is installed inside the collar 20. The cleaning brush 24 removes drill cuttings and other impurities adhering to the surface of the drill bit 7, ensuring that the surface of the drill bit 7 remains clean and reducing wear or clogging problems caused by drill cuttings accumulation. A telescopic column 21 is fixedly connected inside the support frame 19. A support block 23 is fixedly connected to one end of the telescopic column 21. The support block 23 is frustoconical and is engaged with the side wall of the collar 20 to facilitate the assembly and disassembly of the collar 20. A spring 22 is fitted on the outer wall of the telescopic column 21. The two ends of the spring 22 are fixedly connected to the support frame 19 and the support block 23, respectively, providing elastic support. The collar 20 is positioned by the telescopic column 21 and the spring 22, forming a continuous cleaning contact with the drill bit 7, thereby efficiently cleaning the surface of the drill bit 7.

[0038] Working principle: When using the geological exploration pre-drilling device, if it is necessary to disassemble and replace the drill bit 7, during installation, firstly, by rotating the knob 11, the bidirectional screw 10 rotates, causing the first chuck 8 and the second chuck 9 to move towards or in opposite directions within the hollow column 5. When the first chuck 8 and the second chuck 9 are engaged with the clamping plate 12, the connecting column 6 can be securely connected, thereby fixing the drill bit 7 and transmitting rotational power. During disassembly, simply rotate the knob 11 in the opposite direction to release the clamping plate 12 from the first chuck 8 and the second chuck 9, and the connecting column 6 and the drill bit 7 can be removed, thus achieving the effect of facilitating the disassembly and replacement of the drill bit 7.

[0039] During the drilling process, the drill bit 7 is driven by the elevator 2 to pass through the limit frame 13 and enter the ground. The support components inside the limit frame 13 play a supporting and auxiliary cleaning role. At this time, water is injected into the annular water pipe 16 through the water injection pipe 17. Water is sprayed out from multiple nozzles 18 to rinse around the drill bit 7, remove drill cuttings, and cool the drill bit 7. When the drill bit 7 moves up and down and rotates, the cleaning brush 24 inside the collar 20 contacts the drill bit 7 and brushes away the drill cuttings and other impurities attached to the drill bit 7.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
