Embodiment 1

[0027] The rock testing machine bearing chassis of this embodiment, its structure is as attached Figure 5-1 , 5-2As shown, the overall structure is an axisymmetric rotary structure, and the table-top bearing chassis body is surrounded by the bearing chassis body for receiving the leaked seepage medium water during the rock test block penetration test and the debris generated by the test block rupture during the compression test. The receiving plate groove 2 and the connecting flange set on the lower end of the bearing chassis body are used to fix the bearing chassis on the loading base 14 in the triaxial pressure chamber of the rock testing machine. The cross-section of the receiving plate groove is rectangular, and the notch surface of the receiving plate groove is flush with the upper end surface of the carrying chassis body. The center of the lower end surface of the load-bearing chassis body is designed with a lower positioning installation hole 7 for installing the load...

Embodiment 2

[0030] The rock testing machine bearing chassis of this embodiment, its structure is as attached Picture 1-1 , 1-2 , 1-3, the overall structure is an axisymmetric rotary structure, and the table-top bearing chassis body is surrounded by the bearing chassis body for receiving the leakage medium water leaked during the rock test block penetration test and the test block rupture during the compression test The receiving tray groove 2 for the generated debris constitutes. The cross-section of the receiving plate groove is rectangular, and the notch surface of the receiving plate groove is flush with the upper end surface of the carrying chassis body. The center of the lower end face of the load-bearing chassis body is designed with a lower positioning installation hole 1 for installing the load-bearing chassis on the loading base in the triaxial pressure chamber of the rock testing machine.

Abstract

The invention discloses a rock test bearing chassis which mainly comprises a table type bearing chassis body and a bearing disc groove which is formed around the bearing chassis body, wherein the lower end face of the bearing chassis body is provided with a positioning mounting hole used for mounting the bearing chassis on a rock test rig loading base; and the bearing disc groove is used for bearing the leaked osmotic medium water in the rock test block penetration test process and the scraps generated by the rock test block breakage in the compression test process. The adverse effect caused to the testing equipment due to the water leakage and rock test block breakage in the rock test block penetration test process and the compression test process on the rock test rig in the prior art is avoided, the measurement and control sensor mounted on the rock test rig loading base is protected, and the cleaning convenience and rapidness of a three-axis pressure chamber of the rock test rig is improved.

Description

technical field [0001] The invention relates to rock penetration test and compression test technology, more specifically, relates to an auxiliary device for rock test block penetration test and compression test used with a rock testing machine. Background technique [0002] The rock test block is subjected to the penetration test and the compression test on the rock test machine. In the prior art, the rock test block is placed between the upper and lower indenters of the test machine, and the lower indenter is directly placed in the triaxial pressure chamber of the rock test machine. Loaded on the base. The sensors used to measure the deformation and load of the rock test block in the penetration test and compression test, as well as the oil inlet / return ports are all distributed on the loading base located in the triaxial pressure chamber. [0003] When performing a penetration test on a rock test block on a rock testing machine, the stone test block is placed between the ...
