[0002] With the rapid development of my country's economy, geotechnical engineering, as an important support for the construction of infrastructure such as buildings, transportation, and water conservancy, has become increasingly important. Geotechnical engineering exploration and drilling technology, as a key means of obtaining underground geological information, rock samples, and groundwater samples, plays a vital role in the safety and effectiveness of engineering design and construction. However, due to my country's vast territory and complex and changeable geological conditions, traditional drilling technology faces many challenges.

[0003] In the complex process of geotechnical drilling, depending on the exploration objectives, formation characteristics and sample requirements, you may encounter situations where multiple drilling methods such as impact drilling, rotary drilling or sampling drilling are required. The current solution for conventional drilling equipment is to replace different drill bits to achieve processing in different situations. However, when the drilling method needs to be changed, it usually takes extra time to dismantle the old equipment, install the new equipment and debug it.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments. Example 1

[0041] See also Figure 1 to Figure 4 , an efficient drilling device for geotechnical engineering, comprising a first support ring 1 and a second support ring 2, the first support ring 1 and the second support ring 2 are fixedly connected by a linear support 3, a drilling tube 16 for drilling is movably connected in the second support ring 2, a drill bit 20 is arranged at one end of the drilling tube 16, and a drilling spiral sheet 19 is arranged on the drilling tube 16, and also includes:

[0042] The lifting and drilling mechanism is installed at the connection of the drilling tube 16, and is used to control the drilling tube 16 to perform lifting and drilling processing. The lifting and drilling mechanism includes a lifting plate 8 for lifting connection and a top fixed plate 9 for connecting support. The top fixed plate 9 is fixedly connected to the first support ring 1 through a fixed connecting rod 12. The lifting plate 8 is installed on one side of the top fixed plate 9 for lifting and movement.

[0043] Furthermore, the lifting and drilling mechanism also includes a driving connecting rod 7 and a first screw rod 5 for lifting and lowering drive. One end of the driving connecting rod 7 is hingedly mounted on the lifting plate 8, and the other end of the driving connecting rod 7 is hingedly mounted on the moving slider 4. The moving slider 4 is limitedly slidably connected to the inside of the linear support 3. The moving slider 4 is threadedly connected to the first screw rod 5. The first screw rod 5 is rotatably connected to the inside of the linear support 3, and the first screw rod 5 is fixedly connected to the output shaft of the first motor 6. The first motor 6 is fixedly mounted on the linear support 3.

[0044] Furthermore, a plurality of first guide slide bars 11 are fixedly connected to the lifting plate 8 , and the first guide slide bars 11 are limitedly slidably connected to the inside of the guide sleeve 10 , and the guide sleeve 10 is fixedly connected to the top fixed plate 9 .

[0045] Furthermore, a plurality of fixing anchor rods 13 and L-shaped limiting rods 14 are provided on the first support ring 1 for fixing. The fixing anchor rods 13 are movably mounted on the first support ring 1 , and one end of the L-shaped limiting rod 14 is hingedly mounted on a hinge seat 15 , and the hinge seat 15 is fixedly connected to the first support ring 1 .

[0046] Preferably, when drilling, the drilling device can be fixed by fixing the anchor rod 13 and the L-shaped limit rod 14. The drilling device mainly performs corresponding drilling by the drilling spiral blade 19 on the drilling tube 16 and the drill bit 20 at the end.

[0047] When conducting in-depth drilling of rock and soil, the output shaft of the first motor 6 drives the first screw rod 5 to rotate, thereby driving the lifting plate 8 to drive the drilling tube 16 to descend for drilling processing under the threaded connection between the movable slider 4 and the first screw rod 5 and the hinged relationship of the driving connecting rod 7, and the guide sleeve 10 and the first guide slide rod 11 arranged above the lifting plate 8 are telescopically guided, thereby improving the stability of the drilling tube 16 for descending drilling, which is convenient for drilling use. Through this lifting and driving method, stable control of the lifting process of the drilling tube 16 can be achieved, reducing shaking caused by mechanical vibration or imbalance, ensuring that the drilling tube 16 maintains a high degree of stability during the lifting process, and effectively preventing drilling deviations or equipment damage caused by instability.

[0048] It should be particularly noted that the output shaft of the first motor 6 can be driven in forward and reverse directions. Example 2

[0049] like Figures 1 to 12 As shown, based on Example 1, this embodiment further includes a rotary impact drilling mechanism, which is installed inside the drilling barrel 16 and is used to drive the drilling barrel 16 to rotate and perform impact drilling. The rotary impact drilling mechanism includes a sampling barrel 47 and an impact cone 55 for reciprocating impact drilling and a fourth connecting shaft 40 for impact driving. The impact cone 55 is movably installed in the sampling barrel 47, and the sampling barrel 47 is reciprocatingly connected to the inside of the drilling barrel 16. One end of the fourth connecting shaft 40 is movably installed on one side of the pushing block 44 through the ball head 41. The pushing block 44 is installed and connected with the sampling barrel 47 through the push rod 46. The sampling barrel 47 is rotatably connected to one end of the push rod 46.

[0050] Furthermore, the rotary impact drilling mechanism also includes a rotating shaft 34 and a second connecting plate 35 connected to the drilling barrel 16 for driving the pushing block 44 to reciprocate. One end of the fourth connecting shaft 40 is movably connected to the inside of the rotating block 42 through a ball head 41. A ball head groove 45 adapted to the limit connection ball head 41 is provided in the rotating block 42. The rotating block 42 is movably installed on one side of the pushing block 44 through a fifth connecting shaft 43. The other end of the fourth connecting shaft 40 is fixedly connected to the second rotating frame 38. The second rotating frame 38 is rotatably installed on the first rotating frame 37 through a cross connecting shaft 39. The first rotating frame 37 is rotatably connected to the second connecting plate 35 through the third connecting shaft 36. The second connecting plate 35 is fixedly connected to the rotating shaft 34. The rotating shaft 34 is rotatably connected to the first rotating plate 32 and the second rotating plate 33.

[0051] Furthermore, the rotary impact drilling mechanism also includes a sixth connecting shaft 52 and a first connecting shaft 28 for driving the rotating shaft 34 to rotate, the second rotating plate 33 is fixedly connected to the sixth connecting shaft 52, the first rotating plate 32 is fixedly connected to the first connecting shaft 28, the sixth connecting shaft 52 is rotatably connected to the third connecting plate 53, the first connecting shaft 28 is rotatably connected to the first connecting plate 26, and the pushing block 44 is limitedly slidably connected to the second guide slide rod 54, and the second guide slide rod 54 is fixedly connected to the connection between the first connecting plate 26 and the third connecting plate 53.

[0052] Furthermore, the rotary impact drilling mechanism also includes a rotating ring 49 and a linear slider 51 for driving the sampling tube 47 to rotate and move as a guide. The rotating ring 49 is fixedly connected to the sampling tube 47 through a third fixed column 48, and the linear slider 51 is fixedly connected to the inside of the drilling tube 16. A linear slide groove 50 is provided on the rotating ring 49 to be adapted for sliding connection with the linear slider 51.

[0053] Furthermore, the rotary impact drilling mechanism also includes a second motor 17 for driving the rotating shaft 34 to rotate and driving the drilling barrel 16 to rotate for drilling. The first connecting shaft 28 is rotatably connected to the main drive shaft 24 through the first synchronous belt 27. The main drive shaft 24 is fixedly connected to the output shaft of the second motor 17. The second motor 17 is fixedly installed on the lifting plate 8 through the protective cover 18. The main drive shaft 24 is also rotatably connected to the second connecting shaft 29 through the second synchronous belt 59. The second connecting shaft 29 is rotatably installed on the first connecting plate 26. A rotating gear 30 is provided at one end of the first connecting shaft 28 and the second connecting shaft 29. The inner wall of the drilling barrel 16 is provided with a plurality of annular teeth 31 meshing with the rotating gear 30. The first connecting plate 26 is fixedly connected to the lifting plate 8 through the second fixed column 25.

[0054] Furthermore, the rotary impact drilling mechanism also includes a guide slip ring 22 for rotationally guiding the drilling tube 16. The guide slip ring 22 is fixedly connected to the drilling tube 16 through a first fixed column 21. The lifting plate 8 is provided with a guide groove 23 adapted to limit the sliding connection of the guide slip ring 22.

[0055] Preferably, in this embodiment, when performing rotary drilling processing, the main drive shaft 24 is driven to rotate by the output shaft of the second motor 17, thereby driving the rotating gear 30 on the first connecting shaft 28 and the second connecting shaft 29 to rotate under the synchronous driving action of the first synchronous belt 27 and the second synchronous belt 59, thereby driving the drilling barrel 16 to drive the drilling spiral blade 19 and the drill bit 20 to rotate under the meshing connection relationship between the rotating gear 30 and the annular teeth 31 of the inner ring of the drilling barrel 16, thereby realizing rotary drilling processing of rock and soil.

[0056] When the first connecting shaft 28 rotates, the sixth connecting shaft 52 is correspondingly driven to rotate. At this time, the second rotating plate 33 rotates around the sixth connecting shaft 52, and the first rotating plate 32 rotates around the first connecting shaft 28. Since the rotating shaft 34 is rotatably connected to the first rotating plate 32 and the second rotating plate 33, the rotating shaft 34 is in the process of rotating. Since one end of the second connecting plate 35 is movably connected to the second rotating frame 38 through the first rotating frame 37 and the cross connecting shaft 39, the cross connecting shaft 39 is rotatably connected, and one end of the fourth connecting shaft 40 is movably connected to the rotating block 42 through the ball head 41. Under the connection relationship inside, the second connecting plate 35 can be driven to pull the pushing block 44 connected to one end of the fourth connecting shaft 40 to swing back and forth and be connected to the second guide slide bar 54, so that the push rod 46 can drive the sampling tube 47 to move back and forth inside the drilling tube 16. Therefore, under the rotational connection between the sampling tube 47 and the push rod 46 and the limiting guiding action of the linear slider 51, the rotary drilling at the drilling tube 16 and the reciprocating impact processing of the sampling tube 47 at the end of the drilling tube 16 can be realized accordingly. The working mode of impacting and rotating drilling can be realized accordingly without changing the drill bit, which significantly improves the work efficiency.

[0057] The combined effect of impact and rotation can more effectively break rocks. The impact action causes cracks or breaks in the rocks through instantaneous impact force, while the rotation action continuously grinds and scrapes the rock surface through the cutting edge of the drill bit. The combination of the two can accelerate the rock breaking process, significantly shorten the drilling time and improve the drilling efficiency.

[0058] It should be particularly noted that both the main drive shaft 24 and the first connecting shaft 28 are provided with pulleys synchronously connected to the first synchronous belt 27 , and both the main drive shaft 24 and the second connecting shaft 29 are provided with pulleys synchronously connected to the second synchronous belt 59 . Example 3

[0059] like Figures 1 to 13 As shown, based on the above embodiments, this embodiment further includes a sampling control mechanism, which is installed at the internal connection between the impact cone 55 and the sampling tube 47 and is used to control the sampling tube 47 to perform impact or sampling control processing.

[0060] Furthermore, the sampling control mechanism includes a third motor 58 for driving the impact cone 55 for movement control. The impact cone 55 is connected to the interior of the sampling tube 47 by a limiting sliding rod 56, and the impact cone 55 is threadedly connected to the second screw rod 57. The second screw rod 57 is fixedly connected to the output shaft of the third motor 58, and the third motor 58 is fixedly installed inside the sampling tube 47.

[0061] Preferably, in this embodiment, the reciprocatingly telescopic sampling tube 47 and the impact cone 55 can well realize the impact drilling processing of the rock. When it is necessary to sample the internal rock, the third motor 58 controls the second screw rod 57 to rotate accordingly, so that the impact cone 55 can be driven to move in the direction of the third motor 58 under the threaded connection between the impact cone 55 and the second screw rod 57 and the limiting guiding action of the limiting slide rod 56. At this time, the impact cone 55 moves to the inside of the sampling tube 47, so that the end of the sampling tube 47 presents a sampling notch groove, so that the sampling tube 47 can realize the sampling processing of the rock during the reciprocating movement.

[0062] When it is necessary to take out the sample in the sampling tube 47, it is only necessary to drive the second screw 57 to rotate in the opposite direction through the third motor 58, so that the impact cone 55 can push the sample out, which is convenient for later detection and use. The sampling process can be realized accordingly without replacing the sampling head, which means that the sampling process can be realized accordingly without interrupting the drilling process during the drilling process. It not only reduces the time spent on replacing the sampling head, but also avoids the alignment, debugging and other steps that may occur during the replacement process, thereby greatly improving the overall efficiency of drilling sampling, reducing labor costs, and improving the safety and reliability of operations.

[0063] It should be particularly noted that the output shaft of the third motor 58 can be driven in forward and reverse directions.

[0064] It should be particularly noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
