A three-way precise positioning similar simulation roadway micro-drilling rig

Abstract

The invention provides a three-direction accurate locating analog simulation roadway miniature drilling machine which comprises a motor, a locating mechanism, a lifting table mechanism, a motor sliding track, a side standing base and a base guiding track. The base guiding track is fixed on the locating mechanism. A protruding block is arranged in the middle of the base guiding track. The cross section of the protruding block is in a big-end-up trapezoid shape. The lifting table mechanism comprises a front stand column, a back stand column and a lifting table base. The lifting table base and the protruding block of the base guiding track form a guiding track sliding block mechanism. The bottom of a lifting table comprises a pair of side standing base inserting holes. The drilling machine is small in size and can be placed into an analog simulation roadway for hole drilling, by arranging of the side stand base in a matched mode, the miniature drilling machine can work horizontally and vertically, by front-back moving of the lifting table or the side standing base on the base guiding track, the distance between drilled holes in roadway axis direction and at a roadway front section boundary can be located accurately, and operation is easy.

Description

technical field [0001] The invention relates to the field of drilling devices, in particular to a three-way precise positioning similar simulated roadway micro-drilling machine. Background technique [0002] In order to study the stress-strain conditions of underground coal mine roadways, it is often necessary to lay a similar model in the laboratory, that is, a similar simulation experiment, which is an effective experimental method for analyzing and speculating the actual situation on site. It is of great significance to study the control laws of roadway surrounding rocks by conducting similar simulation experiments to explore the essential laws and speculate on-site conditions. [0003] In order to install bolts in the simulated roadway, it is necessary to drill holes in the simulated roadway according to the design requirements of the experiment. Since the simulated roadway excavated in similar simulation experiments has a small space, how to realize accurate drilling in...

AI Technical Summary

Problems solved by technology

However, although this method can drill holes in a small space, it has obvious defects. It can neither guarantee the distance between the drilled holes of the anchor rods nor the direction of the drilled holes, and cannot accurately drill holes in the simulated roadway. The authenticity of the experimental simulation is greatly reduced, thereby affecting the accuracy of the obtained data
