AI Technical Summary

Technical Problem

Vibration of drilling equipment during geotechnical engineering investigation may loosen the surrounding soil and cause instability in the drilling position, affecting construction efficiency and building safety.

Method used

By employing a support mechanism and a monitoring mechanism in conjunction with a multi-stage power adjustment mechanism, the support force and power of the drilling equipment are adjusted in real time to achieve dynamic matching between the four corner supports and the drilling power, thereby reducing the impact load on the drill bit and the motor, reducing wear, and extending the equipment life.

Benefits of technology

It effectively prevents soil loosening and building damage caused by vibration, ensures the smooth and efficient progress of drilling work, and extends the service life of key components.

Abstract

This invention relates to the field of geotechnical engineering technology, specifically disclosing a drilling device for geotechnical engineering exploration, comprising: a drilling body; and a support mechanism, which is disposed on the drilling body and is used to support and adjust the position of the drilling body and to provide feedback on the support information at the four corners. This invention has at least the following beneficial effects: by setting up the support mechanism and the monitoring mechanism, after the drilling body is moved to the required drilling position, the four corners of the drilling body can be supported by the four support mechanisms. During support, the drilling body can be supported by the first hydraulic cylinder and the four support feet can touch the ground respectively. The gas in the airbag is pushed out or pulled out by the connecting rod piston air cylinder and the air guide pipe, thereby driving the fixed shaft on one side of the top slide of the airbag to adjust. In this way, the four fixed shafts can provide feedback on the ground position of the support feet at the four corners.
