Engineering geological exploration drilling machine

Abstract

The invention discloses an engineering geological exploration drilling machine, and relates to the technical field of geological exploration. The engineering geological exploration drilling machine comprises a drilling machine body, a fixed base and a supporting frame movably connected with the surface of the drilling machine body, wherein grips are fixedly connected to the two sides of the drilling machine body, the output shaft end of the drilling machine body is fixedly connected with a rock core pipe through a coupling, the drilling machine body is placed above the fixing frame, at the moment, the grips are clamped in the fixing frame, limiting bolts are rotated, the limiting bolts are inserted into threaded grooves, the fixing frame and the grips are fixed together, the drilling machine body is fixed, the grips are pushed downwards, the grips drive connecting blocks to move downwards in a supporting frame through the fixing frame, at the moment, limiting blocks slides in sliding grooves, balls are driven to roll on the surface of the supporting frame, the rock core pipe is driven to move downwards, and when hard rock is encountered, the drilling machine body can stably drill downwards, and the vertical downward angle is kept.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to an engineering geological survey drilling rig. Background technique [0002] Engineering geology is a discipline that applies the principles of geology to serve engineering applications. The main research contents involve geological hazards, rocks and Quaternary sediments, rock mass stability, earthquakes, etc. Engineering geology is widely used in various stages of engineering planning, survey, design, construction and maintenance. The purpose of engineering geology is to find out the geological conditions of various engineering sites, conduct a comprehensive evaluation of the site and its related geological problems, analyze and predict the possible changes and effects of geological conditions under the action of engineering buildings, Select the optimal site and propose engineering measures to solve unfavorable geological problems, so as to provide a reliable scient...
