An automatic detection device and method for cylindrical rock samples

Abstract

The invention discloses an automatic detection device for a cylindrical rock sample. The automatic detection device comprises a base, a vertical side plate unit A, a vertical side plate unit B, a sample base, a sliding test platform unit and a control processor, wherein the vertical side plate unit A, the vertical side plate unit B and the sample base are all mounted on the base; the vertical sideplate unit A and the vertical side plate unit B are oppositely arranged on two sides of the sample base; the sliding test platform unit is horizontally arranged above the sample base, and the vertical side plate unit A and the vertical side plate unit B are connected through a sliding test platform; the control processor is connected with the vertical side plate unit A, the vertical side plate unit B, the sliding test platform and the sample base. The invention further provides an automatic detection method for the cylindrical rock sample. The automatic detection device and method for the cylindrical rock sample have beneficial effects as follows: with combination of a laser displacement test technology, an electric telescopic device system and a computer technology, multiple parameters such as flatness, verticality, parallelism, sample size, density and the like of the rock sample are measured simultaneously, and the degree of automation is high.

Description

Technical field [0001] The invention relates to geotechnical engineering indoor test technology, in particular to an automatic detection device and method for cylindrical rock samples. Background technique [0002] The preparation and selection of rock samples are important steps of indoor rock testing. The flatness, perpendicularity, parallelism, and size of the rock sample end face have a significant impact on the test results. Such problems as eccentric compression and stress concentration due to non-compliance with the standard will cause the entire test to fail. For cylindrical rock specimens, most of them are processed by coring the original rock and grinding the end face. [0003] According to the contents of "2001 Water Conservancy and Hydropower Engineering Rock Test Regulations", the height of the rock specimen used in the indoor test is 48-54mm, and the ratio of the specimen height to the diameter should be 2.0-2.5; the allowable deviation of height, diameter or side le...

Problems solved by technology

[0004] At present, rulers, knife-edge squares, vernier calipers and other tools are usually combined for detection, and the detection process is cumbersome; at the same time, the detection accuracy of the verticality detection (light gap method) involved is poor. Therefore, it is necessary to Improvement on existing technology
