Description

Technical Field

[0001] The utility model belongs to the field of drilling equipment, and particularly relates to a geotechnical drilling device for reservoir dam safety assessment. Background Technique

[0002] A reservoir dam is an engineering structure used to block water flow and store water resources, mainly used to control rivers and create reservoirs. The safety assessment of reservoir dams involves a comprehensive analysis of their structure, function, and environmental impact. Among them, the collection of geotechnical materials is an important task. By analyzing geotechnical samples, the physical and chemical properties of the soil can be determined, such as density, particle size, strength, and permeability. These characteristics directly affect the stability and bearing capacity of the dam;

[0003] According to the application number: 202323020331.5, a geotechnical drilling device is disclosed, which relates to the field of geotechnical engineering technology. It includes a main frame. Two telescopic arms are fixedly installed in the middle of the upper end inside the main frame. The telescopic end of the telescopic arm is fixedly installed with an installation frame. A transmission shaft is movably connected to the middle of the installation frame. Guide frames are fixedly connected to the middle of the left and right sides of the installation frame. Cross bars are fixedly connected to the left and right sides of the lower end of the main frame. A guide rod is fixedly connected to the middle of the upper end of the cross bar. The guide rod is movably connected to the guide frame. Support rods are fixedly connected to the middle of the front and rear sides of the transmission shaft through shaft sleeves. This comparative case uses the guide frame and the guide rod to maintain the stability of the installation frame during the drilling process, enabling the installation frame to move up and down smoothly, avoiding shaking or deviation of the installation frame during drilling due to vibration. At the same time, the shaft sleeve fixed with the support rod is movably connected to the guide rail to achieve stable support for the transmission shaft;

[0004] This comparative case well solves the problem that the fixation of the transmission shaft is not considered thoroughly. The vibration transmitted by the drill pipe during the drilling process may cause the transmission rotating shaft to deviate or be damaged, and the drilling frame is prone to shaking or deviation during the drilling process due to vibration. However, since the heights around the bottom of the main frame are the same, the device cannot be used on the ground with a large slope, thereby reducing the practicability of the device.
