A high-precision drilling anti-deviation device for geotechnical engineering survey

Abstract

The invention discloses a high-precision drilling anti-deviation device for geotechnical engineering survey, which belongs to the technical field of drilling devices. The device mainly includes a support seat, a drilling component, an anti-deviation adjustment sleeve, a coarse adjustment element, a fine adjustment element, a cleaning element, a control element, and a power supply; the adjusted position of the drill pipe is abutted by setting the anti-deviation adjustment sleeve, The drill pipe is fixed throughout the drilling process, which improves the stability of the drill pipe, reduces the shaking degree of the drill pipe during rotation, and avoids the deviation of the drilling tool from affecting the drilling accuracy; the drill pipe needs to be adjusted by the coarse adjustment element. The approximate position adjustment of the drilling operation can reduce the fine-tuning time and increase the work efficiency. The specific position of the drill rod can be fine-tuned through the fine-tuning element to improve the accuracy of the drilling equipment to the drilling point. The adjustment process is easy to operate and saves time. Safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of drilling devices, in particular to a high-precision drilling deviation prevention device for geotechnical engineering survey. Background technique [0002] With the prosperity and development of our country's economy, various construction projects have sprung up like mushrooms after rain, with sparkling reservoirs and tall buildings row upon row. Among various civil engineering projects, geotechnical engineering occupies a very important position. [0003] Geotechnical engineering is a new technical system established in the practice of civil engineering in European and American countries in the 1960s. Geotechnical engineering investigation is to identify, analyze and evaluate the geology, environmental characteristics and geotechnical engineering conditions of the construction site. The activities of survey documents are the basis of design and construction. If the survey work is not in place, bad engine...

Problems solved by technology

[0004] In the geotechnical engineering investigation process, in order to make the drilling more accurate, it is necessary to design a drilling anti-deviation device for geotechnical engineering investigation, but the existing geotechnical drilling anti-deviation device has the following defects: 1) drilling The stability of the rod is poor, and the degree of shaking of the drill rod during the rotation process is large, which causes the deviation of the drilling tool and affects the drilling accuracy; 2) The specific drilling position of the drill rod cannot be fine-tuned, which reduces the accuracy of the drilling equipment to align the drilling point 3) the used drill pipe cannot be cleaned, and it is easy to cause rock fragments to enter the interior of the equipment, thereby causing damage to the equipment and increasing maintenance costs
