[0015] The present invention also provides a method for using the above-mentioned geological exploration drilling device for geotechnical engineering, specifically including the following steps:

[0016] S1. Use conventional drilling equipment to complete the drilling work of the first stage hole;

[0017] S2. Move the geotechnical engineering geological exploration drilling device to the working position so that the drilling hole corresponds to the opening of the first stage hole. Then install the first section of the drill rod at the clamping head position and install the sampling drill bit at the bottom of the first section of the drill rod.

[0018] S3. The Z-axis drive unit moves the horizontal axis rotary table downwards. The drive assembly and clamping head follow the downward movement of the horizontal axis rotary table, inserting the sampling drill bit and the first drill rod into the opening of the first stage hole. Then, the clamping assembly is controlled to clamp the top of the first drill rod. The clamping head is manipulated to release the first drill rod. The Z-axis drive unit then moves the horizontal axis rotary table upwards, with the drive assembly and clamping head following the upward movement. This pushes the second drill rod, which is currently tilted and placed on the storage rack, onto the upper pipe fixture. The horizontal axis rotary table then drives the drive assembly and clamping head to rotate, adjusting the tilt angle of the clamping head. The upper pipe fixture is used to adjust the top height of the second drill rod. The tilt angle is adjusted so that the top height of the second drill rod is consistent with the height of the chuck, and the tilt angle of the second drill rod is consistent with the tilt angle of the chuck. Then, the chuck is manipulated to clamp the top of the second drill rod. Then, the Z-axis drive drives the horizontal axis rotary table to move upward. The drive assembly and the chuck follow the horizontal axis rotary table to move upward. The chuck drives the second drill rod to break free from the restriction of the storage rack. Finally, the horizontal axis rotary table is adjusted to a vertical state. The Z-axis drive drives the horizontal axis rotary table to move downward. The drive assembly and the chuck follow the horizontal axis rotary table to move downward. The bottom end of the second drill rod is aligned with the top end of the first drill rod and connected together.

[0019] S4. Repeat step S3 to connect the third section of the drill rod until the required number of drill rods are connected. After the drill rod connection reaches the drilling depth, the drill rod is pushed down by the Z-axis drive component and the drive assembly drives the drill rod to rotate to complete the drilling work of the second stage hole.

[0020] The present invention has the following beneficial effects:

[0021] (1) By using a multi-section drill rod, the present invention can complete the drilling work of deep holes. The main structure of the geological exploration drilling device for geotechnical engineering is small and belongs to the small and medium-sized exploration equipment, which is easy to move and use. Putting it into deep drilling operations can save manpower and material costs. Furthermore, the geological exploration drilling device for geotechnical engineering is designed with a horizontal axis rotary table, which can manipulate the drive components and the clamping head to rotate and move at an angle. A pipe rack is also designed on the bottom platform. The L-shaped pipe rack is inclined and can hold multiple drill rods at an angle. When used with the pipe tooling, the connection of multiple drill rods can be completed easily and efficiently, further reducing the workload of deep drilling operations.

[0022] (2) The present invention designs a horizontal axis rotary table, which drives the rotating frame by adjusting the motor to drive the bevel gear set (first bevel gear and second bevel gear) and the reduction gear set (small gear and large gear), thereby smoothly controlling the angle of the drive component. Furthermore, a positioning pin is designed to keep the drive component in a stable vertical state, which can maintain the stability of the drive component during drilling and ensure the stability of the drilling process.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] This invention provides a geological exploration drilling device for geotechnical engineering, such as... Figures 1-10 As shown, it includes a base platform 1, an arched support 2, a guide support 3, a horizontal axis rotary table 5, a drive assembly 6, a clamping head 7, a Z-axis drive component, a drill rod 8, a sampling drill bit 9, a pipe storage rack 15, a pipe mounting fixture 16, and a clamping assembly 18.

[0037] The base platform 1 is either a vehicle-mounted platform or a stable frame erected on the ground. A vehicle-mounted platform offers the advantage of easy mobility. A drilling hole 1a is provided on the bottom surface of the base platform 1. The diameter of the drilling hole 1a is larger than the diameter of the sampling drill bit 9, allowing the sampling drill bit 9 to extend downwards through the drilling hole 1a. An arched bracket 2 is fixedly installed on the top of the base platform 1. The arched bracket 2 is a large arch structure with an angle greater than 300°. At least one vertically arranged guide bracket 3 is fixedly installed between the inner top of the arched bracket 2 and the top surface of the base platform 1. The guide bracket 3... The movement of the horizontal axis rotary table 5 serves as a guide. The guide bracket 3 is parallel to the direction of the Z-axis drive component. The horizontal axis rotary table 5 is slidably connected to the guide bracket 3, enabling the horizontal axis rotary table 5 to move stably. A drive assembly 6 is fixedly installed on the rotating frame 504 of the horizontal axis rotary table 5. The drive assembly 6 provides rotational driving force for drilling. A clamping head 7 is fixedly installed at the bottom output end of the drive assembly 6. The drive assembly 6 can drive the clamping head 7 to rotate. The clamping head 7 is used to clamp and fix the top of the uppermost drill rod section 8. The Z-axis drive component is mounted on the arched bracket. 2. On the horizontal axis rotary table 5, the Z-axis drive unit is used to drive the horizontal axis rotary table 5 to slide up and down along the guide bracket 3. The two ends of the drill rod 8 are male and female, respectively. There are multiple drill rods 8, which are distributed vertically. The male and female ends of two adjacent drill rods 8 are connected in a mating manner. For example, both the male and female ends can be threaded. The top of the uppermost drill rod 8 is fixedly installed with the clamping head 7, that is, the clamping head 7 clamps and fixes the top of the uppermost drill rod 8. The bottom of the lowermost drill rod 8 is fixedly installed with a sampling drill bit 9. The sample drill bit 9 has teeth at the bottom, which can complete the drilling and sampling work. The pipe rack 15 is fixedly installed on the top of the base 1. The pipe rack 15 is an L-shaped inclined arrangement. The drill rod 8 rests on one side of the pipe rack 15, so that the drill rod 8 is also in an inclined state. The operator can manipulate the drill rod 8 to fix it on the pipe rack 15. An upper pipe fixture 16 is installed on one side of the pipe rack 15. The upper pipe fixture 16 is used to adjust the inclination angle of the drill rod 8. The clamping assembly 18 is installed on the base 1. The clamping assembly 18 is used to clamp the drill rod 8 located inside the drill hole 1a.

[0038] During the drilling process, the Z-axis drive unit pushes the horizontal axis rotary table 5 to move downwards, while the drive assembly 6 drives the clamping head 7 to rotate, which in turn drives the drill rod 8 and the sampling drill bit 9 to rotate, thus completing the drilling work.

[0039] This invention employs a multi-section drill rod 8 for connection, enabling drilling of deep holes. Furthermore, the invention designs a structure consisting of a horizontal axis rotary table 5, a pipe rack 15, a pipe mounting fixture 16, and a clamping assembly 18, which facilitates easy and efficient connection of the drill rods 8. Specifically, the first drill rod section is installed at the clamping head 7, and a sampling drill bit 9 is installed at the bottom of the first drill rod section. The Z-axis drive unit drives the horizontal axis rotary table 5 downwards, and the drive assembly 6 and the clamping head 7 follow the horizontal axis rotation. The rotary table 5 moves downwards, and the sampling drill bit 9 and the first drill rod section are inserted into the lower orifice. Then, the clamping assembly 18 is controlled to clamp the top of the first drill rod section. The user manipulates the clamping head 7 to release the first drill rod section. The Z-axis drive unit drives the horizontal axis rotary table 5 to move upwards. The drive assembly 6 and the clamping head 7 follow the horizontal axis rotary table 5 upwards. The operator pushes the second drill rod section, which is in an inclined state and placed on the pipe rack 15, onto the upper pipe fixture 16. Then, the horizontal axis rotary table 5 drives the drive assembly 6 and the clamping head 7 to rotate, adjusting... The tilt angle of the clamping head 7 is adjusted, and the top height and tilt angle of the second drill rod are adjusted using the upper pipe fixture 16, so that the top height of the second drill rod is consistent with the height of the clamping head 7, and the tilt angle of the second drill rod is consistent with the tilt angle of the clamping head 7. Finally, the clamping head 7 is manipulated to clamp the top of the second drill rod, and then the Z-axis drive is used to drive the horizontal axis rotary table 5 to move upward. The drive assembly 6 and the clamping head 7 follow the horizontal axis rotary table 5 to move upward, and the clamping head 7 drives the second drill rod to break free from the restriction of the pipe rack 15. Finally, the second drill rod is adjusted to a vertical position by the horizontal axis rotary table 5. Then, the Z-axis drive unit drives the horizontal axis rotary table 5 to move downward. The drive assembly 6 and the clamping head 7 follow the horizontal axis rotary table 5 to move downward. The bottom end of the second drill rod is aligned with the top end of the first drill rod and connected together. Then, the above operation is repeated to connect the third drill rod, the third drill rod, and so on, until the required number of drill rods 8 are connected. Finally, the Z-axis drive unit pushes down the drill rod 8, and the drive assembly 6 drives the drill rod to rotate to complete the deep hole drilling work.

[0040] In Example 1, as Figure 1 and Figure 2 As shown, an auxiliary support 4 is fixedly connected to the side of the arched support 2. The auxiliary support 4 includes a structural support part located inside the arched support 2 and a stable support part located outside the arched support 2 with its bottom end supported on the ground. The structural support part is used to improve the stability of the arched support 2, and the stable support part is used to improve the stability of the geological exploration drilling device for geotechnical engineering with the ground. The structural support part and the stable support part can be an integral structure.

[0041] In Example 1, as Figure 8 and Figure 9As shown, the horizontal axis rotary table 5 includes a frame 501, a first shaft 507, a rotating frame 504, a small gear 5011, a large gear 508, a second shaft 509, a second bevel gear 5013, a first bevel gear 5010, and an adjusting motor 5012. The back of the frame 501 is open, and a cover is installed on the back of the frame 501. The cover can be opened to facilitate the installation of the internal structures of the frame 501. A side frame 502 is fixedly connected to the side of the frame 501. The side frame 502 is provided with a sliding sleeve hole that cooperates with the guide bracket 3. The side frame 502 and the guide bracket 3 are slidably connected. The guide bracket 3 is used to guide the horizontal axis rotary table 5. The first shaft 507 is rotatably connected to the frame 501, and the first end of the first shaft 507 is located outside the frame 501. The first end of the first shaft 507 is fixedly connected to the rotating frame 504, and the second end of the first shaft 507 is located... Inside the frame 501, a large gear 508 is fixedly installed at the second end of the first shaft 507. The second shaft 509 is rotatably installed on the inner side wall of the frame 501, and a small gear 5011 and a first bevel gear 5010 are fixedly installed on the second shaft 509. The small gear 5011 meshes with the large gear 508 for transmission. The adjusting motor 5012 is fixedly installed on the side of the frame 501, and the output shaft of the adjusting motor 5012 passes through the side wall of the frame 501. A second bevel gear 5013 is fixedly installed on the output shaft of the adjusting motor 5012, and the second bevel gear 5013 meshes with the first bevel gear 5010 for transmission.

[0042] The regulating motor 5012 provides rotational power, and its output shaft drives the second bevel gear 5013 to rotate. The second bevel gear 5013 meshes with the first bevel gear 5010, thereby driving the first bevel gear 5010 to rotate. The first bevel gear 5010 is fixedly connected to the second shaft 509, so the second shaft 509 will also rotate, driving the small gear 5011 fixed to the second shaft 509 to rotate as well. The small gear 5011 meshes with the large gear 508 to achieve speed reduction transmission, driving the large gear 508 to rotate, and in turn driving the first shaft 507 and the rotating frame 504 to rotate.

[0043] A lug 505 is fixedly connected to the side of the rotating frame 504. A first pin hole 503 corresponding to the eye hole of the lug 505 is opened on the front of the frame 501. A positioning pin 506 is inserted into both the eye hole of the lug 505 and the first pin hole 503. When adjusting the rotation of the rotating frame 504, the positioning pin 506 needs to be pulled out. When drilling, it is necessary to ensure the stability of the drive assembly 6. At this time, the positioning pin 506 can be installed. With the positioning pin 506 installed, the drive assembly 6 is in a vertical position.

[0044] In Example 1, as Figure 5 , Figure 7 and Figure 8As shown, the drive assembly 6 includes a mounting frame 601 and a hydraulic drive motor 602. The mounting frame 601 is fixedly connected to the rotating frame 504 of the horizontal axis rotary table 5. The mounting frame 601 and the horizontal axis rotary table 5 form a T-shaped structure. The hydraulic drive motor 602 is fixedly mounted on the top of the mounting frame 601. The bottom end of the output shaft of the hydraulic drive motor 602 passes through the mounting frame 601, and a clamping head 7 is fixedly mounted on the bottom end of the output shaft of the hydraulic drive motor 602. The hydraulic drive motor 602 is used to drive the clamping head 7 to rotate, thereby driving the drill rod 8 held by the clamping head 7 to rotate, and thus driving the sampling drill bit 9 at the bottom end of the drill rod 8 to perform drilling.

[0045] In Example 1, as Figure 5 and Figure 7 As shown, the clamping head 7 includes a first rotating disk 701, a sliding frame 702, a first clamping member 704, and a second clamping member 705. The first rotating disk 701 is fixedly mounted to the bottom end of the output shaft of a hydraulic drive motor 602, which drives the first rotating disk 701 to rotate. The sliding frame 702 is horizontally fixedly mounted to the bottom of the first rotating disk 701, and a center plate 703 is fixedly provided in the middle of the sliding frame 702. The first clamping member 704 and the second clamping member 705 are both slidably connected to the sliding frame 702, and are located on both sides of the center plate 703. A pull screw assembly is connected between the first clamping member 704 and the second clamping member 705. The pull screw assembly includes a screw and nuts located at both ends of the screw. When the nuts are tightened, they can push the first clamping member 704 and the second clamping member 705 toward the middle to clamp together, that is, the first clamping member 704 and the second clamping member 705 clamp and fix the top end of the drill rod 8. Conversely, when the nuts of the pull screw assembly are loosened, the first clamping member 704 and the second clamping member 705 can be separated, and the top end of the drill rod 8 can be loosened.

[0046] In Example 1, as Figure 1 , Figure 5 and Figure 6As shown, the Z-axis drive component includes a threaded rod 10, a first guide head 11, a second guide head 12, a nut assembly 13, and a main drive motor 14. The bottom end of the threaded rod 10 is fixedly installed on the top of the horizontal axis rotary table 5. The first guide head 11 and the second guide head 12 are both fixedly connected to the arched bracket 2, and the threaded rod 10 is located inside the first guide head 11 and the second guide head 12. The first guide head 11 and the second guide head 12 are both used to guide the threaded rod 10. A gap is provided between the first guide head 11 and the second guide head 12. The nut assembly 13 is located between the first guide head 11 and the second guide head 12, and the nut assembly 13 is threadedly engaged with the threaded rod 10. The main drive motor 14 is fixedly connected to the arched bracket 2, and a drive gear 14a is fixedly installed on the output end of the main drive motor 14. The outer side of the nut assembly 13 is provided with teeth that mesh with the drive gear 14a. When in use, the main drive motor 14 is connected to the hydraulic power source, and the drive gear 14a of the main drive motor 14 rotates, thereby driving the nut assembly 13 to rotate. The nut assembly 13 is threadedly engaged with the threaded rod 10, thereby driving the threaded rod 10 to move up and down.

[0047] In Example 1, as Figure 3 and Figure 4 As shown, the storage rack 15 includes a connecting base plate 1501, which is fixedly installed on the top surface of the base platform 1. A short support plate 1502 and a long support plate 1503 with a 90° angle are fixedly connected to the top of the connecting base plate 1501. The long support plate 1503 is close to the drilling hole 1a of the base platform 1. A notch 1504 is provided on the front side of the long support plate 1503. A limiting short plate 1505 is fixedly connected to the top of the short support plate 1502. The limiting short plate 1505 is nearly parallel to the long support plate 1503. Several limiting nails 1506 are fixedly connected to the upper surface of the long support plate 1503 and the side away from the notch 1504. The limiting nails 1506 are used to limit the drill rod 8 from rolling down. Multiple drill rods 8 rest against the long support plate 1503, and the bottom end of the drill rod 8 abuts against the short support plate 1502. The short support plate 1502, the long support plate 1503, and the limiting short plate 1505 form a groove-shaped structure at the bottom to limit the bottom end of the drill rod 8.

[0048] In Example 1, as Figure 4As shown, the upper pipe fixture 16 includes a second rotating disk 1602 and a hydraulic telescopic component 1605. A mounting shaft is fixedly connected to the back of the second rotating disk 1602. A cylindrical mounting seat 1601 is provided on the back of the long support plate 1503. The mounting shaft is rotatably mounted inside the cylindrical mounting seat 1601, allowing the second rotating disk 1602 to rotate freely. A support roller 1603 and a connecting horizontal shaft 1604 are fixedly connected to the front of the second rotating disk 1602. The support roller 1603 and the connecting horizontal shaft 1604 are distributed at both ends of a diameter line on the front side of the second rotating disk 1602. The first end of the hydraulic telescopic component 1605 is rotatably connected to the connecting horizontal shaft 1604, and the second end of the hydraulic telescopic component 1605 is hinged to the top surface of the base platform 1.

[0049] The user rolls the drill rod 8 inside the storage rack 15 to adjust its position. One of the drill rods 8 is rolled to the position of the notch 1504. At this time, since the drill rod 8 is not supported by the long support plate 1503, the drill rod 8 tilts. One side of the drill rod 8 rests on the support roller 1603. By controlling the length of the hydraulic telescopic component 1605, the second rotating disk 1602 is driven to rotate, thereby adjusting the position of the support roller 1603 and thus adjusting the tilt angle of the drill rod 8.

[0050] In Embodiment 1, the clamping assembly 18, as shown... Figure 10 As shown, the system includes a U-shaped frame 1801, a second telescopic member 1802, a first clamping arm 1804, a second clamping arm 1805, a first spring 1807, and a second spring 1808. The U-shaped frame 1801 is fixedly connected to the top surface of the base platform 1. The main body of the second telescopic member 1802 is fixedly connected to the outer side of the U-shaped frame 1801. The telescopic end of the second telescopic member 1802 passes through the U-shaped frame 1801, and an H-shaped frame 1803 is fixedly installed at the telescopic end of the second telescopic member 1802. One end of the first clamping arm 1804 and one end of the second clamping arm 1805 are rotatably connected via a connecting shaft 1806, which is fixedly connected to the top surface of the base platform 1. Next, a first spring 1807 is fixedly connected between the outer side of the first clamping arm 1804 and the inner side of the U-shaped frame 1801, and a second spring 1808 is fixedly connected between the outer side of the second clamping arm 1805 and the inner side of the U-shaped frame 1801. A first clamping part 1809 is provided on the inner side of the end of the first clamping arm 1804 away from the connecting shaft 1806, and a second clamping part 18010 is provided on the inner side of the end of the second clamping arm 1805 away from the connecting shaft 1806.

[0051] In use, the second telescopic member 1802 pushes the H-shaped frame 1803 forward, and the two sides of the H-shaped frame 1803 press against the outer sides of the first clamping arm 1804 and the second clamping arm 1805, so that the first clamping arm 1804 and the second clamping arm 1805 overcome the elastic force of the first spring 1807 and the second spring 1808 to clamp and fix the drill rod 8; conversely, when the second telescopic member 1802 moves backward, the first clamping arm 1804 and the second clamping arm 1805 return to their original position under the elastic tension of the first spring 1807 and the second spring 1808.

[0052] In Example 1, as Figure 1 As shown, a ladder frame 17 is fixedly installed on the top surface of the base 1. The ladder frame 17 is used by the user when operating the clamping head 7.

[0053] Example 2: A method for using the geological exploration drilling device for geotechnical engineering described in Example 1 is provided, specifically including the following steps:

[0054] S1. Use conventional drilling equipment to complete the drilling work for the first stage of the hole.

[0055] S2. Move the geotechnical engineering geological exploration drilling device to the working position, aligning the drilling hole 1a with the opening of the first stage hole. Then, install the first drill rod section at the clamping head 7 position and install the sampling drill bit 9 at the bottom of the first drill rod section. The Z-axis drive unit drives the horizontal axis rotary table 5 to move downwards, and the drive assembly 6 and clamping head 7 follow the horizontal axis rotary table 5 to move downwards. The sampling drill bit 9 and the first drill rod section are inserted into the opening of the first stage hole. Then, control the clamping assembly 18 to clamp the top of the first drill rod section. Manipulate the clamping head 7 to release the first drill rod section. The Z-axis drive unit drives the horizontal axis rotary table 5 to move upwards, and the drive assembly 6 and clamping head 7 follow the horizontal axis rotary table 5 to move upwards. The operator pushes the second drill rod section, which is in an inclined state and placed on the pipe rack 15, onto the upper pipe fixture 16. Then, the horizontal axis rotary table 5 drives the drive assembly 6 and clamping head 7 to rotate, adjusting the inclination angle of the clamping head 7, and using the upper pipe fixture 16 to adjust the second section... The height and inclination angle of the drill rod's top end are adjusted so that the height of the second drill rod's top end is consistent with the height of the clamping head 7, and the inclination angle of the second drill rod is consistent with the inclination angle of the clamping head 7. Finally, the clamping head 7 is manipulated to clamp the top end of the second drill rod. Then, the Z-axis drive unit drives the horizontal axis rotary table 5 to move upward. The drive assembly 6 and the clamping head 7 follow the horizontal axis rotary table 5 to move upward. The clamping head 7 drives the second drill rod to break free from the restriction of the storage rack 15. Finally, the horizontal axis rotary table 5 is adjusted to a vertical state. Then, the Z-axis drive unit drives the horizontal axis rotary table 5 to move downward. The drive assembly 6 and the clamping head 7 follow the horizontal axis rotary table 5 to move downward. The bottom end of the second drill rod is aligned with the top end of the first drill rod and connected together. Then, the above operation is repeated to connect the third drill rod until the required number of drill rods are connected. Finally, the drilling work of the second stage hole is completed by the Z-axis drive unit pushing down the drill rod 8 and the drive assembly 6 driving the drill rod to rotate.
