Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a geological exploration drilling device for geotechnical engineering. Background Technology

[0002] In the field of geotechnical engineering geological exploration, drilling equipment is a key device for obtaining the physical and mechanical properties of underground rock and soil. In existing technologies, geological exploration drilling equipment usually consists of a fixed base, a power system, a drilling actuator, and a support structure. The power system drives the drilling actuator to drill into the geological body, and the support structure ensures the stability of the equipment during operation. To adapt to different terrain conditions, some equipment adopts an adjustable outrigger structure, which allows for manual adjustment of the support height to meet basic horizontal operation requirements. It is widely used in engineering fields such as building foundation exploration and mineral resource exploration.

[0003] When using existing drilling equipment, the connection between the fixed base and the ground is not stable enough, and it is prone to slippage in soft or sloping terrain. The overall disassembly and height adjustment of the equipment is cumbersome, time-consuming and labor-intensive, reducing the efficiency of exploration operations. It is also inconvenient to move and has poor portability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution:

[0005] A geological exploration drilling device for geotechnical engineering includes a fixing base assembly for fixing the installation position of the geological exploration drilling device. The assembly includes two first horizontal plates and a second horizontal plate. Two perforated plates are provided on the two first horizontal plates, and two support assemblies are fitted onto the two perforated plates. A third horizontal plate is installed between the two support assemblies. Each support assembly includes a support plate and a threaded ring. A cover plate is installed on the top of the support plate, and threaded posts are provided on the sidewalls of the support plates.

[0006] One end of the through-hole plate is threaded into the threaded ring. An insertion hole is formed inside the support plate, and an extension rod is fitted inside the insertion hole and housed within the support plate. A threaded hole is formed on the top surface of the support plate. Two threaded cylinders are connected on the cover plate, and a pull plate is placed between the two cylinders. Bolts are threaded into the cylinders, and the ends of the bolts are threaded into the threaded holes. A limiting rod is used to fix the fixing base assembly to the geological surface.

[0007] Both the second and third horizontal plates have threaded sleeves installed inside, and the limiting rod is threadedly engaged with the threaded sleeve.

[0008] Preferably, it also includes a top plate and two support rods, the two support rods are installed on the side walls of two support components, a stop plate is installed between the two support rods, and a sliding hydraulic cylinder is installed at the top of the support rods by screws, the telescopic end of the sliding hydraulic cylinder is installed on the side wall of the top plate.

[0009] Preferably, a mounting bracket is installed on the top surface of the top plate using screws, and the power system is installed on the mounting bracket.

[0010] Preferably, the power system includes a diesel engine, a gearbox, a coupling, and a drive shaft, with the drive shaft extending through the bottom surface of the top plate and the drilling execution system mounted on the drive shaft.

[0011] Preferably, the drilling execution system includes a drill pipe, a drill bit, a rotary drive mechanism, and a propulsion mechanism, with an extension rod cooperating with the drill pipe.

[0012] Preferably, a control switch is installed on the top surface of the top plate, and the control switch is electrically connected to the power system and the drilling execution system.

[0013] Preferably, two baffles are provided on the second horizontal plate, and there is a gap between the two baffles, the gap being the same as the thickness of the top plate.

[0014] Preferably, two casters are installed at the bottom of the interior of each of the two first horizontal plates.

[0015] As an improvement to the above technical solution, the coordinated design of the fixed base assembly, support assembly and limiting rod significantly improves the fixing stability. The setting of the moving wheels facilitates the rapid movement of the device between different survey points, reducing transportation time and labor costs. The device structure design takes into account a variety of working conditions and has good adaptability and flexibility.

[0016] The beneficial effects of this invention are:

[0017] 1. The present invention comprises two first horizontal plates, a second horizontal plate, and a perforated plate forming a fixed base assembly. The threaded column and threaded ring of the support assembly are connected, allowing for flexible adjustment of the position and angle of the support assembly. The limiting rod, through a threaded sleeve, cooperates with the second and third horizontal plates to penetrate deep into the geological surface, providing stable support. In soft or complex terrain, it can effectively prevent the device from shifting or tilting, providing a reliable foundation for drilling operations and ensuring the accuracy and reliability of drilling data.

[0018] 2. The extension rod of the support component of the present invention can be stored in the support plate. When needed, it can be inserted into the hole to cooperate with the drill rod, which facilitates the adjustment of the drilling height. The cooperation between the sliding hydraulic cylinder and the top plate can flexibly adjust the height position of the power system and the drilling execution system, quickly adapt to different drilling depth requirements, and the control switch can uniformly control the power system and the drilling execution system, simplifying the operation process and effectively improving the overall operation efficiency.

[0019] 3. The support component of the present invention can be finely adjusted in horizontal position through threaded column and threaded ring. The combination of cover plate, threaded cylinder and bolt can realize vertical tightening adjustment, which facilitates the adjustment of the installation state of the support component and fixed seat component of the geological exploration drilling device, and is more convenient to move, thus improving the transport portability of the geological exploration drilling device.

A stop plate 401 is installed between the two support rods 4. A sliding hydraulic cylinder 402 is installed at the top of the support rods 4 by screws. The telescopic end of the sliding hydraulic cylinder 402 is installed on the side wall of the top plate 5.

[0035] In this embodiment, the top plate 5, support rods 4, abutment plate 401, and sliding hydraulic cylinder 402 cooperate with each other to form a stable and flexible support adjustment structure. The two support rods 4 are installed on the side wall of the support assembly 2 to provide basic support for the top plate 5. The abutment plate 401 enhances the connection stability between the support rods 4. One end of the sliding hydraulic cylinder 402 is fixed to the top of the support rod 4, and the telescopic end is connected to the side wall of the top plate 5, so as to flexibly adjust the height and position of the top plate 5, thereby accurately adjusting the power system 7 and the drilling execution system 9 to meet the needs of different drilling conditions and improve the flexibility and applicability of the device operation.

[0040] In this invention, two movable wheels 104 are installed at the bottom of the interior of each of the two first horizontal plates 101.

[0041] In this embodiment, the movable wheel 104 facilitates the movement and relocation of the geological exploration drilling device, improving the convenience and flexibility of the device.

[0042] The method of use and working principle of the geological exploration drilling device are as follows: When in use, first use the moving wheels 104 at the bottom of the first horizontal plate 101 to transport the device to the exploration point and stop it. Then rotate the upper limit rod 3 of the second horizontal plate 102 to ensure that the fixed seat assembly 1 is fixed on the exploration ground. According to the usage requirements, the hole plate 105 and the threaded column 202 are used to rotate and adjust the angle installation so that the support assembly 2 can be unfolded. The third horizontal plate 15 on the support assembly 2 is supported on the exploration ground. Rotate the limit rod 3 again so that the support rod 4 can be perpendicular to the ground. Rotate the bolt 13 to separate the cover plate 10 from the support plate 201. Then, take out the extension rod 14 as needed to assemble the drill rod. Use the sliding hydraulic cylinder 402 to adjust the height of the top plate 5 to position the drill bit. Finally, start the power system 7 and the drilling execution system 9 by operating the switch 8 to drill. After completion, reverse the operation to store the device.
