Rock tension-compression shear seepage test device

Abstract

The invention discloses a rock tension-compression shear seepage test device. The test device comprises a test device body, a bottom of the test device body is fixedly connected with an operation table, a connecting table is fixedly connected to a middle of a bottom of an operation table, a connecting block is fixedly connected to a left side of a bottom of the connecting table, a first supportingrod is hinged to a bottom of the connecting block, a first sliding groove is fixedly connected to the bottom of the connecting table, and a first sliding block is slidably connected to an inner wallof the first sliding groove and hinged to a second supporting rod. The test device is provided with a driving device, a force is generated by the driving device, the force acts on a screw rod througha transmission wheel, a push force is applied to the screw rod, the screw rod pushes the sliding block to move, so that the supporting rods are lifted, the test device is lifted, the displacement of the device can be controlled through a switch rod, the test device can be descended, the horizontal height of the test device can be adjusted by utilizing a rotating force generated by the device, andthe operation of an operator during a test is facilitated.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a rock tension-compression shear seepage test device. Background technique [0002] The shear strength of rock is the ability of rock to resist shear damage, and it is one of the important characteristics required in rock mechanics research. In the field of geotechnical engineering, test methods are widely used to determine the shear strength index of rock. [0003] However, the horizontal height of the workbench of the existing test device cannot be changed, but most of the rocks tested are very heavy. During the test preparation stage, the test personnel often need to use additional lifting devices to lift the rocks to the test workbench. The complexity of the test is increased, and the existing test device cannot be easily transported, so there is an urgent need for a rock tension-compression shear seepage test device that can change the horizontal height of the te...

[0003] However, the horizontal height of the workbench of the existing test device cannot be changed, but most of the rocks tested are very heavy. During the test preparation stage, the test personnel often need to use additional lifting devices to lift the rocks to the test workbench. The complexity of the test is increased, and the existing test device cannot be easily transported, so there is an urgent need for a rock tension-compression shear seepage test device that can change the horizontal height of the test device workbench and facilitate transportation.
