Description

Technical Field

[0001] The present invention relates to the field of rock mass engineering investigation, and particularly to a drilling device and method for geotechnical construction investigation. Background Art

[0002] Geotechnical engineering aims to solve problems related to rock and soil engineering, including problems such as foundations and substructures, slopes, and underground engineering. During geotechnical engineering investigation, drilling is often required to obtain geological information.

[0003] Rock exploration is the process of detailed investigation and analysis of underground rocks to obtain information about the properties, composition, structure, and characteristics of rocks. Key technologies include drilling technology, geophysical exploration, etc. The main characteristics of these technologies and methods include: Drilling technology: By conducting drilling operations underground, rock samples are obtained for laboratory analysis to understand the physical properties, chemical composition, and pore characteristics of rocks; Geophysical exploration: By measuring physical field parameters underground, such as seismic wave propagation velocity, electromagnetic field changes, gravity, and magnetic field characteristics, the properties and structure of rocks are inferred. In summary, the comprehensive application of rock exploration technologies and methods can provide comprehensive rock information and provide an important basis for fields such as geological research, mineral resource exploration, engineering construction, and environmental assessment.

[0004] A drilling device and drilling process for geotechnical engineering investigation disclosed in Chinese Patent CN112324355A, wherein the drilling device includes a frame, drill pipes, and a number of legs. The drill pipes and legs are connected to the frame for lifting and lowering, and a first driving member for driving the rotation of the drill pipes is connected to the frame. A linkage mechanism for driving the linkage lifting of each leg is also connected to the frame.

[0005] However, compared with the existing technology and the comparison scheme, the following problems still exist in the actual use of this drilling device:

[0006] When the rock and soil ground where the device is placed has many potholes, the device will shake and tilt. When the part that needs to be drilled and explored is located at a non-horizontal position such as a slope, it is not convenient to level the drilling device, which may easily cause the drill pipe to be skewed. The skewed drill pipe is likely to result in poor drilling quality of the exploration hole, and ultimately easily affect the accuracy of the investigation results. Summary of the Invention

[0011] Preferably: A rotating frame is arranged on the support frame, a hydraulic cylinder, a first limiting slide bar and a fixing bolt are arranged on the rotating frame, and a limiting block is arranged at the end of the first limiting slide bar away from the rotating frame.

[0012] Preferably: The connecting frame is arranged at the output end of the hydraulic cylinder, a first driving member is arranged on the connecting frame, a first screw rod is arranged at the output end of the first driving member, the first screw rod is rotatably connected to the connecting frame, a chute is arranged on the connecting frame, the position of the chute corresponds to the position of the first screw rod, a second limiting slide bar is arranged at the bottom of the connecting frame, a first connecting hole is arranged on the connecting frame, and the connecting frame is slidably connected to the first limiting slide bar through the first connecting hole.

[0013] Preferably: The first moving frame is provided with a connecting screw hole and a second connecting hole, the first moving frame is threadedly connected to the first screw rod through the connecting screw hole, the first moving frame is slidably connected to the second limiting slide bar through the second connecting hole, a second driving member is arranged on one side of the first moving frame, a second screw rod is arranged at the output end of the second driving member, the second screw rod is rotatably connected to the first moving frame, the axis of the second screw rod is perpendicular to the axis of the first screw rod, and a second moving frame is threadedly connected to the second screw rod, and the second moving frame is slidably connected to the first moving frame.

[0014] Preferably: The drilling assembly includes a third driving member, the third driving member is fixedly installed on the second moving frame, a coupling is arranged at the output end of the third driving member, a drill rod is connected to the output end of the third driving member through the coupling, and a drill bit is arranged at the end of the drill rod away from the coupling.

[0015] Preferably: The third screw rod is threadedly connected to the support frame.

[0016] Preferably: The cross section of the first sliding member is an inverted triangle, and the two connecting balls are respectively in contact with the two bottom surfaces of the first sliding member.

[0017] Preferably, the elastic member is disposed between the limiting plate and the second sliding member.

[0018] Preferably, the number of the connecting ball, the second sliding member, the connecting column, the limiting plate, the elastic member and the anchor nail is two each.

[0019] A usage method of a drilling device for geotechnical construction exploration includes the following steps:

[0020] S1: When the position to be drilled and explored is on a slope, rotate the third screw rod through the adjusting head. The third screw rod drives the connecting shell to move. The connecting shell drives the connecting column through the second sliding member. The connecting column drives the anchor nail to move through the limiting plate. The anchor nail is inserted into the ground to fix the device.

[0021] S2: Adjust different fixing components according to the inclination angle of the slope to ensure the horizontality of the support frame, thereby avoiding the situation of the drill pipe being skewed when the drilling component conducts drilling exploration, ensuring the quality of the exploration borehole, and thus ensuring the accuracy of the drilling exploration result.

[0022] S3: Before conducting drilling exploration, start the first driving member and the second driving member. The first driving member drives the first moving frame to move through the first screw rod. The second driving member drives the second moving frame to move through the second screw rod. The second moving frame drives the drilling component to move to adjust the position of the drilling component.

[0023] S4: When the drilling component moves to the position where drilling exploration is required, turn off the first driving member and the second driving member, and start the third driving member. The third driving member drives the drill pipe through the coupling, and the drill pipe drives the drill bit to rotate.

[0024] S5: At the same time, start the hydraulic cylinder. The hydraulic cylinder drives the first moving frame through the connecting frame. The first moving frame drives the drilling component to move downward, and the rotating drill bit conducts drilling exploration.

[0025] S6: When there are many pits and bumps at the position to be drilled and explored, two different anchor nails on the same fixing component are respectively inserted into different positions on the ground. Due to the uneven distribution of the ground pits and bumps, the horizontal heights of the ground at the positions where different anchor nails are located are not the same.

[0026] S7: After the limiting plate on the anchor nail at the position with a relatively higher horizontal height contacts the ground, the limiting plate pushes the connecting ball to move upward through the connecting column. The connecting ball pushes the connecting ball corresponding to the position with a relatively lower horizontal height to move downward through the first sliding member.

[0027] S8: The connecting ball corresponding to the position with a relatively low horizontal height pushes against the connecting column corresponding to the position with a relatively low horizontal height. The connecting column corresponding to the position with a relatively low horizontal height drives the anchor nail corresponding to the position with a relatively low horizontal height to move downward through the limiting plate and insert into the ground at the position with a relatively low horizontal height, ensuring that the anchor nails at different positions can be inserted into the ground to fix the device. Thus, when the device is used in a place with many potholes, the situation of shaking or tilting can be avoided, ensuring the stability of the device during drilling exploration and thus ensuring the effect of drilling exploration.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] When the position where drilling exploration is required is on a slope, different fixing components can be adjusted according to the inclination angle of the slope, so as to ensure the horizontality of the support frame, further avoiding skew during drilling exploration, ensuring the quality of the exploration borehole, and ensuring the accuracy of the exploration results. When there are many potholes at the position where drilling exploration is required, it can ensure that the anchor nails at different positions can be inserted into various parts of the ground with uneven horizontal heights to fix the device. Thus, when the device is used in a place with many potholes, the situation of shaking or tilting can be avoided, ensuring the stability of the device during drilling exploration and thus ensuring the effect of drilling exploration.

[0055] A method for using a drilling device for geotechnical construction investigation includes the following steps:

[0056] S1: When the position where drilling investigation is required is on a slope, rotate the third screw 501 through the adjusting head 502. The third screw 501 drives the connecting shell 503 to move. The connecting shell 503 drives the connecting column 507 through the second sliding member 506. The connecting column 507 drives the anchor nail 510 through the limiting plate 508. The anchor nail 510 is inserted into the ground to fix the device.

[0057] S2: Adjust different fixing components 5 according to the inclination angle of the slope to ensure the horizontality of the support frame 1, thereby avoiding the situation of the drill pipe 403 being skewed when the drilling component 4 conducts drilling investigation, ensuring the quality of the exploration borehole, and thus ensuring the accuracy of the drilling investigation result.

[0058] S3: Before conducting drilling investigation, start the first driving member 201 and the second driving member 303. The first driving member 201 drives the first moving frame 3 through the first screw 202. The second driving member 303 drives the second moving frame 305 through the second screw 304. The second moving frame 305 drives the drilling component 4 to move to adjust the position of the drilling component 4.

[0059] S4: When the drilling assembly 4 moves to the position where drilling exploration is required, turn off the first driving member 201 and the second driving member 303, start the third driving member 401, and the third driving member 401 drives the drill pipe 403 through the coupling 402, and the drill pipe 403 drives the drill bit 404 to rotate;

[0060] S5: At the same time, start the hydraulic cylinder 102. The hydraulic cylinder 102 drives the first moving frame 3 through the connecting frame 2, and the first moving frame 3 drives the drilling assembly 4 to move downward, and the rotating drill bit 404 conducts drilling exploration;

[0061] S6: When there are many potholes at the position where drilling exploration is required, two different anchor nails 510 on the same fixing assembly 5 are respectively inserted into different positions on the ground. Due to the uneven distribution of the ground potholes, the horizontal heights of the ground at the positions where the different anchor nails 510 are located are not the same;

[0062] S7: After the limiting plate 508 on the anchor nail 510 at the position with a relatively higher horizontal height contacts the ground, the limiting plate 508 pushes the connecting ball 505 to move upward through the connecting column 507, and the connecting ball 505 pushes the connecting ball 505 corresponding to the position with a relatively lower horizontal height to move downward through the first sliding member 504;

[0063] S8: The connecting ball 505 corresponding to the position with a relatively lower horizontal height pushes the connecting column 507 corresponding to the position with a relatively lower horizontal height, and the connecting column 507 corresponding to the position with a relatively lower horizontal height drives the anchor nail 510 corresponding to the position with a relatively lower horizontal height to move downward through the limiting plate 508 and inserts it into the ground at the position with a relatively lower horizontal height, ensuring that the anchor nails 510 at different positions can be inserted into the ground to fix the device, thereby avoiding the situation of shaking or tilting when the device is used in places with many potholes, ensuring the stability of the device during drilling exploration, and thus ensuring the effect of drilling exploration.
