Description

Technical Field

[0001] The present invention belongs to the technical field of geotechnical engineering, and more specifically, particularly relates to a drilling device for geotechnical engineering investigation. Background Technique

[0002] Drilling is one of the main means of geotechnical engineering investigation. A drill is used to drill downward from the ground surface to form a cylindrical borehole in the formation to identify and divide the formation. Core samples, ore samples, and soil samples can be obtained from different depths in the borehole for analysis and research to determine the physical and mechanical properties and indexes of rocks and soil layers, providing the needs for design. Currently, when conducting geotechnical engineering investigation, a drilling device is required.

[0003] For example, a drilling and sampling device for geotechnical engineering investigation disclosed in the publication number: CN220791132U includes a box body. A second sliding groove is provided on the inner wall of the box body. A first support plate is slidably connected to the inner side of the second sliding groove. A second motor is fixed to one side of the bottom of the first support plate. Two support blocks are fixed to one side of the bottom of the first support plate. The bottom of the support block is fixed with a second support plate slidably connected to the inner side of the second sliding groove. A speed reducer is fixed to one side of the bottom of the second support plate. When a drilling device with a large weight needs to be moved, only the output shafts of multiple first motors drive the lead screws to rotate, so that the two limit blocks approach each other. At the same time, the support rod is made to push the fixed block downward, and at the same time, the connecting frame, the rotating shaft, and the pulley move downward. When multiple pulleys abut against one side of the ground, the drilling device can be moved in parallel at this time. The operation is simple and convenient, improving the convenience of moving the drilling device and reducing the use cost of the drilling device.

[0004] Based on the above patent solution and the existing related technologies, the currently used drilling devices for geotechnical engineering investigation still have the following problems: 1. After drilling is completed, it is necessary for the staff to manually clean the drilling bit, and automatic cleaning of the drilling bit cannot be achieved; 2. Usually, positioning is achieved by relying on the braking function on the rollers, resulting in the device being prone to movement during drilling, affecting the drilling effect; 3. Generally, there is also a lack of a pushing structure, resulting in the soil and rock slag after drilling being easily introduced into the drilling hole when the drilling bit is pulled out, increasing the subsequent cleaning time. Therefore, we provide a drilling device for geotechnical engineering investigation to solve the above problems. Summary of the Invention

[0018] Compared with the prior art, the drilling equipment for geotechnical engineering investigation has the following beneficial effects:

[0019] First, when the staff starts the two linear electric cylinders A and the drive motor in the present invention, the drilling bit slowly moves downward, realizing the automatic drilling of the rock and soil; when the output shafts of the two linear electric cylinders A extend, the two drilling positioning rods automatically insert into the two positioning circular holes, playing a limiting role on the rectangular positioning frame, so that the rectangular positioning frame can only move downward along the two drilling positioning rods, avoiding the shaking of the drilling bit.

Also, since the four helical springs B404 are sleeved outside the four circular guide shafts 401 and the four helical springs B404 are located below the two pedal stabilizing frames 402, when the staff separates from the two pedal stabilizing frames 402, the two pedal stabilizing frames 402 automatically move upward under the action of the four helical springs B404, making the bottoms of the eight circular stabilizing rods 403 higher than the bottoms of the four moving rollers 104.

[0049] Please refer to Figure 10 As shown, the auxiliary mechanism 500 includes: a linear cylinder B501, a dovetail connection block 502, and a connection track 503. There are four linear cylinders B501 in total, and the four linear cylinders B501 are fixedly installed on the moving frame 101. There are four dovetail connection blocks 502 in total, and the four dovetail connection blocks 502 are fixedly installed on the output shafts of the four linear cylinders B501. There are four connection tracks 503 in total, and the four connection tracks 503 are slidably installed outside the four dovetail connection blocks 502. The auxiliary mechanism 500 also includes: an arc-shaped auxiliary plate 504 and a strong magnet 505. There are two arc-shaped auxiliary plates 504 in total, and the two arc-shaped auxiliary plates 504 are fixedly installed inside the four connection tracks 503, and the inner walls of the two arc-shaped auxiliary plates 504 are in contact with the drilling bit 304.

[0051] Working principle: First, the staff move the device to the drilling area through four moving rollers 104. Then, the staff step on two stepping stabilizers 402. Under the action of the staff's weight, the two stepping stabilizers 402 can automatically move downward, enabling eight circular stabilizer rods 403 to automatically insert into the rock and soil at the drilling area, playing a positioning role for the moving frame 101 and making the moving frame 101 more stable. Then, the staff start two linear cylinders A 202 and the drive motor 302. When the staff start the two linear cylinders A 202 and the drive motor 302, the drilling bit 304 slowly moves downward to achieve automatic drilling of the rock and soil. When the output shafts of the two linear cylinders A 202 extend, the two drilling positioning rods 103 automatically insert into the two positioning round holes 2051, playing a limiting role for the rectangular positioning frame 205, so that the rectangular positioning frame 205 can only move downward along the two drilling positioning rods 103 to prevent the drilling bit 304 from shaking. When the staff separate from the two stepping stabilizers 402, the two stepping stabilizers 402 automatically move upward under the action of four spiral springs B 404, making the bottoms of the eight circular stabilizer rods 403 higher than the bottoms of the four moving rollers 104. After drilling, when the staff start the drive motor 302, the linkage cleaning frame 303 can contact the two V-shaped cleaning frames 102. When the linkage cleaning frame 303 contacts the left V-shaped cleaning frame 102, the movable mounting plate 204 drives the drilling bit 304 to move to the right. When the linkage cleaning frame 303 separates from the left V-shaped cleaning frame 102, the movable mounting plate 204 resets to the left under the action of four spiral springs A 206. When the linkage cleaning frame 303 contacts the right V-shaped cleaning frame 102, the movable mounting plate 204 drives the drilling bit 304 to move to the left. When the linkage cleaning frame 303 separates from the right V-shaped cleaning frame 102, the movable mounting plate 204 resets to the right under the action of four spiral springs A 206. This makes the movable mounting plate 204 drive the drilling bit 304 to move left and right reciprocally, facilitating the automatic dropping of the rock and soil on the drilling bit 304 and achieving rapid cleaning of the drilling bit 304. Then, the staff retract the output shafts of the four linear cylinders B 501. At this time, the two arc-shaped auxiliary plates 504 move outward simultaneously, playing an automatic pushing role for the rock and soil residues after drilling, preventing the rock and soil residues from entering the drilling hole when the drilling bit 304 is pulled out. After the device is used, the staff can pull up the two arc-shaped auxiliary plates 504 to make a certain distance between the bottoms of the two arc-shaped auxiliary plates 504 and the ground, preventing the bottoms of the two arc-shaped auxiliary plates 504 from being knocked.
