Problems solved by technology

Hand-held ordinary drills are often used for test pieces of general size, but the verticality in the vertical direction and the position control in the vertical direction cannot be guaranteed during operation, and the depth of the drill hole cannot be measured. Only by testing and measuring can the depth of the drilled hole be determined, which is cumbersome; at the same time, it is necessary to drill holes from different angles during the test operation, and ordinary hand-held drills cannot be kept consistent with the preset angle during operation. It is impossible to measure the depth of drilling in the inclined direction

Abstract

The invention discloses a hole-drilling-sampling accurate-positioning portable drilling machine device for a concrete sample and a method. The device comprises a drilling machine for carrying out hole drilling sampling on the sample, a stretchable sleeve is fixed to the top of the drilling machine, an outer sleeve body of the stretchable sleeve and a rack are fixed, and a scale mark is marked on the outer surface of an inner sleeve body of the stretchable sleeve to indicate the drilling depth of the drilling machine during working of the drilling machine. According to the hole-drilling-sampling accurate-positioning portable drilling machine device for the concrete sample and the method, as the stretchable sleeve is arranged at the top end of the drilling machine, and the scale mark is arranged on the sleeve, during drilling of the drilling machine, the depth of the drilling machine in the vertical direction or other directions is effectively determined, and visible and convenient effects are achieved; due to the arrangement of the inner spherical surface of an X-axis guide rail and the fitting with the top of the stretchable sleeve, the drilling machine can carry out slant drilling relative to the center axis of the test sample, and fixed-angle slant drilling of the drilling machine can be achieved in cooperation with the arrangement of an angle disc; due to the arrangement of an X axis, a Y axis and a lifting mechanism, the drilling machine can move in two-dimensional or three-dimensional space, and can be accurately positioned by setting the scale mark.

Description

technical field [0001] The invention relates to a drilling rig device, in particular to a portable drilling rig device and a method for precise positioning of drilling samples for concrete specimens. Background technique [0002] In a large number of infrastructure constructions in my country, the key investment and rapid development of high-speed railways, tunnels, roads and bridges, and water conservancy projects have further increased the requirements for the stability and safety of engineering projects. In order to realize the stability and safety of engineering projects, a large number of tests need to be carried out in the early stage, among which numerical analysis and model tests are the two most important methods today. Therefore, model tests have been widely used in geotechnical engineering such as slope engineering, tunnel engineering, and concrete engineering. [0003] In the model test, it is often necessary to analyze the stress and strain inside the concrete ...
