Description

Technical Field

[0001] The utility model belongs to the technical field of land drilling, and particularly relates to a geotechnical engineering drilling device. Background Art

[0002] A geotechnical engineering drilling device is a piece of equipment used in geotechnical engineering surveys and foundation construction. It is mainly used to obtain the physical and mechanical properties of underground soil and rock, providing necessary geological data for engineering design and construction. It can more effectively obtain detailed information about underground soil and rock, providing a scientific basis for the design and construction of geotechnical engineering, thereby ensuring the project quality.

[0003] For the existing geotechnical engineering drilling device, the device is moved to a suitable position, then the fixing frame of the drilling device is fixed at a designated position, and then the drilling module is controlled to operate. While the drilling module controls the drill bit to rotate and move downward to control the drill bit to penetrate into the soil layer, the surrounding soil quality is involved into the sampling groove opened on the drill bit, so as to achieve the purpose of sampling. When in use, to ensure the fixed position of the drill bit during drilling and prevent the deviation of the drilling device position, it is necessary for personnel to use tools to firmly insert the limit pins on the fixing frame into the soil, so as to ensure the firm fixation of the whole drilling device. However, when using tools to hammer multiple limit pins on the fixing frame into the soil, personnel need to spend a lot of time and energy, increasing the workload of the staff and being not conducive to personnel use.

[0023] As Figure 2 、 3As shown in the figure, the positioning module includes sliding frames 201 symmetrically and slidably arranged on both sides of the chassis 101.

An electric control unit two for driving the positioning seats 202 to move is also arranged on the chassis 101. The electric control unit one includes an adjusting screw rod 206 rotatably arranged at the top end inside the positioning seat 202. The adjusting screw rod 206 is respectively threadedly connected to the adjacent slide columns 204. Electric motors two 207 are arranged on the upper surfaces of the positioning seats 202. The output shafts of the electric motors two 207 are respectively fixed to the adjacent adjusting screw rods 206 through couplings. The electric control unit two includes hydraulic rods two 208 symmetrically arranged inside the front and rear sides of the chassis 101. The telescopic ends of the hydraulic rods two 208 are respectively connected and fixed to the adjacent sliding frames 201.

[0025] When drilling is required during geotechnical work, after moving the chassis 101 to a suitable position through external equipment, the electric motor two 207 is controlled to operate through the control board 301, so that the output shaft of the electric motor two 207 drives the connected adjusting screw rod 206 to rotate. Then, through the threaded relationship between the adjusting screw rod 206 and the slide column 204, the slide column 204 slides between the guide rail 203, so that the slide column 204 drives the limit pin 205 to insert into the soil to fix the position of the chassis 101.

The operation of the first hydraulic rod 109 is regulated through the control panel 301, so that the telescopic end of the first hydraulic rod 109 drives the sliding seat 106 to slide between the slide rails 105, so that the sliding seat 106 drives the rotating drill bit 107 to drill downward into the soil, so that the surrounding soil quality is involved into the sampling groove formed on the drill bit 107 to sample the soil. When the drill bit 107 penetrates into the soil to a certain depth, the first motor 108 is regulated by the control panel 301 to be turned off, and the telescopic end of the first hydraulic rod 109 is retracted to realize the drilling of the drill bit.
