It is crucial for construction projects. With the development of the economy, the pace of urbanization has accelerated, and more and more buildings are being built. The demand for geotechnical engineering investigation has gradually increased. Drilling equipment is needed for drilling work during the investigation. Drilling equipment is an auxiliary device commonly used in geotechnical investigation.

[0003] At present, in the related technology, after searching, the utility model with patent publication number CN217055046U discloses a drilling device, including: a bearing platform, on which a connecting hole is opened; a first support column and a second support column, which are fixedly connected to the bearing platform on opposite sides of the connecting hole; a movable plate, whose opposite ends are movably connected to the first support column and the second support column respectively; a first driving assembly, which is drivingly connected to the movable plate; a first driving member, which is fixedly connected to the movable plate; and a connecting member, whose first end is fixedly connected to the output shaft of the first driving member.

[0004] Regarding the above-mentioned related technologies, when in use, although the drilling operation is carried out through the provided drill rod and drill bit, the labor intensity of manual labor is reduced, which is beneficial to improving work efficiency, and the drill rod and the connecting parts are detachably connected, which is convenient for replacing the drill rod, but the applicant has found that since a lot of mud is attached to the drill rod of the drilling device after use, personnel are required to clean the drill rod and other components separately to avoid affecting the next use of the drilling device, which is insufficient in practicality.

[0005] Therefore, we propose a drilling device. Utility Model Content

[0033] A drill rod 6, which is detachably connected to the output shaft of the driving motor 5;

[0034] Two connecting seats 7, both connecting seats 7 are correspondingly arranged in the U-shaped base 1, and the two connecting seats 7 have arc-shaped plates 8 fixedly connected to opposite ends thereof, and the other ends of the arc-shaped plates 8 are detachably connected to cleaning steel brushes 9;

[0035] Auxiliary components, the auxiliary components are arranged on the U-shaped base 1, and are used to assist the mounting plate 4 to perform vertical displacement;

[0036] The moving component is arranged at the bottom of the U-shaped base 1 and is used to drive the U-shaped base 1 to perform moving operations.

[0037] When the drilling device is in use, a moving component can be set, and under the action of the moving component, the U-shaped base 1 can be moved accordingly. When conducting exploration operations on geotechnical engineering, the driving motor 5 can be started, and the driving motor 5 will drive its drill rod 6 to rotate. At the same time, by starting the electro-hydraulic push rod 2, under the mutual cooperation of the electro-hydraulic push rod 2, the connecting plate 3, and the mounting plate 4, the driving motor 5 drives the drill rod 6 to move vertically, and then the purpose of drilling the geotechnical engineering is achieved through the rotating drill rod 6. After the drilling operation is completed, the two cleaning steel brushes 9 can be closely fitted with the outer surface of the drill rod 6 through the mutual cooperation of the set connecting seat 7 and the arc plate 8, so as to achieve the purpose of cleaning the drill rod 6.

[0038] exist Figure 1-3 Middle: The auxiliary component includes two vertical plates 10, both of which are fixedly welded on the U-shaped base 1, wherein a T-shaped slot is provided in the vertical plate 10, and a T-shaped block 11 is vertically slidably connected in the T-shaped slot, and the mounting plate 4 is fixedly welded between the two T-shaped blocks 11.

[0039] The drilling device, through the arrangement of this structure, ensures that the mounting plate 4 can stably perform vertical displacement through the cooperation of the vertical plate 10, the T-slot and the T-block 11, thereby preventing the drill rod 6 from deviating during operation.

[0040] exist Figure 1-4 Middle: The moving assembly includes four pillars 12, and the four pillars 12 are correspondingly arranged at the bottom of the U-shaped base 1, and the other end of the pillar 12 is detachably connected with a self-locking universal wheel 13.

[0041] The drilling device, with the cooperation of the support column 12 and the self-locking universal wheel 13, enables the U-shaped base 1 to move accordingly, thereby improving the convenience of use.

[0042] exist Figure 1-4 Middle: The drill rod 6 is detachably connected to the output shaft of the driving motor 5 through a mounting collar 14, one end of the U-shaped base 1 is fixedly connected to a strip seat 15, and the connecting seat 7 is fixedly connected to a strip handle 16 for facilitating pushing the U-shaped base 1.

After the U-shaped base 1 is moved to a suitable position, the self-locking universal wheel 13 can be locked to prevent it from slipping during use. When conducting exploration operations on geotechnical engineering, the driving motor 5 is started, and the driving motor 5 drives the drill rod 6 to rotate. At the same time, the electro-hydraulic push rod 2 is started, and the driving motor 5 drives the drill rod 6 to move vertically under the mutual cooperation of the electro-hydraulic push rod 2, the connecting plate 3, and the mounting plate 4, so that the driving motor 5 drives the drill rod 6 to move vertically, and then the geotechnical engineering is drilled through the rotating drill rod 6. When the drilling operation is completed, the cleaning steel brush 9 can be closely fitted with the drill rod 6 through the mutual cooperation of the connecting seat 7 and the arc plate 8, so that the surface of the drill rod 6 can be cleaned.
