Fragile transverse plane grinding machine used for rock test

Abstract

The invention discloses a fragile transverse plane grinding machine used for a rock test. The fragile transverse plane grinding machine comprises a pedestal, a workbench mechanism, an actuating mechanism and a clamping mechanism, a workbench is connected with the pedestal through an elastic component and is limited to a press height by a stop block, sand paper is arranged on the workbench, the actuating mechanism uses a crank slide block principle to realize linear repetitive motion from motor rotation to a guide rod, the clamping mechanism is connected with the guide rod for clamping a rock sample, the rock sample is driven by the motion mechanism, the bottom performs reciprocating motion on the sand paper, and thereby polishing is realized. The grinding machine realizes the stable contact of the rock sample and the sand paper as well as automatic grinding, requirement of rock mechanics test on the extremely fragile rock sample can be satisfied, rate of section edge damage of the rock sample is reduced, and a traditional form of preparation of the fragile rock by artificial operation can be avoided. The structure is simple, the application of the grinding machine is convenient, and the grinding machine is convenient for popularization to the field of the preparation of the rock sample used for indoor rock mechanics test.

Description

technical field [0001] The invention relates to the technical field of rock mechanics tests, in particular to an end face grinding machine suitable for extremely brittle rock (such as coal rock, etc.) samples. Background technique [0002] The earth's surface is covered by a layer of rock about 60-120 kilometers thick. As the most widely distributed natural material in the crust, rock is closely related to engineering fields such as civil engineering, mining, and water conservancy. Some authoritative scholars in the world today propose that the 21st century is the century of underground space development and utilization. With the continuous expansion of the city scale, the scarce resources such as land and water are becoming more and more tense, and it has become an important issue to promote the sustainable development of the city, build a high level of disaster prevention and mitigation, and build a resource-saving and environment-friendly society and city. move. The con...

AI Technical Summary

Problems solved by technology

[0012] The present invention aims at the lack of functions of the previous rock grinder that cannot meet the requirements of precise grinding tests on extremely brittle rocks (such as coal rocks), and its main purpose is to provide a core end face grinder for extremely brittle rock tests, which can meet the requirements of rock mechanics tests. Accurate grinding of standard rock samples of different specifications can improve the success rate of extremely brittle rock sample preparation and promote the research of rock mechanics tests
