Abstract

The invention relates to the technical field of preparing a rock sample for testing, and particularly relates to a rotatable type regular hexagonal rock sample cutting device, which solves the problems that rock samples with conventional shapes adopted in the existing tests cannot completely reflect the deformation and destruction of complicated rock layers. The rotatable type regular hexagonal rock sample cutting device comprises a testbed and a counter top, wherein a disk with scales is arranged in the middle of the counter top, a connecting bush which is concentric to the disk is fixedly arranged on the lower part of the counter top, the connecting bush is in internally threaded connection with an adjustment shaft, the upper end of the adjustment shaft is connected with a crank, the crank is fixedly provided with an indicator in the radial direction of the disc, a mounting block is fixedly arranged on the lower end of the adjustment shaft, a principal axis is connected with a cutterhead symmetrically on two ends of the mounting block, a hydraulic motor is fixedly arranged on the front end of the mounting block, and a cooling device is fixedly arranged on the rear end of the mounting block. The invention provides a hexagonal rock sample cutting device better reflecting the true deformation and destruction form of the rock sample, the truer test data compared with the traditional quadrangular rock sample or cylindrical rock sample can be finally obtained, and the rotatable type regular hexagonal rock sample cutting device has more profound significance on the study on thedeformation and destruction form of the rock layers of complex landform.

Description

technical field [0001] The invention relates to the technical field of rock sample preparation devices for testing, in particular to a rotatable regular hexagonal prism rock sample cutting device. Background technique [0002] Coal resources are one of the most important resources in our country. How to mine safely and efficiently is directly related to the national economy and people's livelihood. However, with the increase of mining efforts, coal mine accidents occur from time to time. According to statistics, the most important factor affecting coal mine safety and efficient mining is One of the factors is the control of the stability of the overlying strata above the coal seam and the coal floor strata. [0003] The deformation and failure of rock formations during mining is one of the main reasons for mine damage. The mechanism of failure and deformation of the overlying strata in the upper part of the coal seam and the coal seam floor is a scientific problem that needs...
