Abstract

The invention discloses an automatic manufacturing and maintaining device for a rock test piece. The device is characterized by comprising a test piece box, a moistening box, a mold, a stirring barrel, a stirring blade, a stirring rod, a motor (stirring), a servo motor, a vertical column, a cross beam, a screw rod, a polishing rod, a nut, a hydraulic cylinder, an arc-shaped clamp, a hydraulic press head, a connecting rod (stirring), a hydraulic pump, a connecting rod (hydraulic pump), an oil pipe (1), an oil pipe (2), a motor (workbench), a rack, a workbench, a humidity controller, a mold base, a humidity sensor, a mold, a control panel, a spray nozzle and a mold bracket which are connected with each other. The automatic stirring and automatic unloading of the rock-similar test piece can be realized; the model material can be automatically compressed; the automatic manufacturing for the rock test piece can be realized; the model test piece is maintained under the same humidity, so that the uniform of the maintaining humidity can be guaranteed and the accuracy of the test piece manufacturing can be further guaranteed.

Description

technical field [0001] The invention relates to the technical field of automatic production of test pieces of similar materials, in particular to a device for automatic production of rock test pieces, automatic compression molding and maintenance under humidity control. Background technique [0002] The properties of rock mechanics have an important impact on mining engineering, civil engineering, and petroleum engineering. In the rock formation environment where underground engineering is located, there are various complex structural surfaces, which have different degrees of influence on the mechanical properties of rock mass. It brings great difficulty and uncertainty to the stability control of underground engineering. The mechanical properties of rocks need to be determined by rock mechanics experiments, and the sampling of original rocks is more complicated. Therefore, the ratio of similar materials is adopted to simulate various mechanical properties of original rocks,...
