Multi-blade multi-angle rock breaking device for rock ripper

Abstract

The invention discloses a multi-blade multi-angle rock breaking device for a rock ripper. The device comprises a self-reaction force frame body, an annular confining pressure loading workbench, a Z-direction servo actuator, an X-direction servo actuator, a Y-direction internal servo actuator, a horizontal dual-layer linear guide rail, a three-direction pressure sensor and the like, wherein the lateral moving direction of a rock test piece is set as an axis X; the propelling direction of the rock test piece is set as an axis Y; a direction which is vertical to the breaking surface of the rock test piece is set as an axis Z; the X-direction servo actuator is arranged between the horizontal dual-layer linear guide rail and the annular confining pressure loading workbench; the Y-direction internal servo actuator is arranged between the horizontal dual-layer linear guide rail and the self-reaction force frame body; and the Z-direction servo actuator is arranged between a guide rail guide mechanism and the self-reaction force frame body. In the device, the annular confining pressure loading function of rock is simulated, so that the rock test piece is closer to real geological conditions, parameter measuring values such as a blade distance and the like are more accurate, the design level of the rock ripper is raised, and tunnel construction accidents are controlled.

Description

technical field [0001] The invention relates to a multi-knife and multi-angle rock breaking test device for simulating a rock boring machine under rock confining pressure loading conditions in the field of rock boring machines. Background technique [0002] At present, the rock tunneling machine is the main equipment in the field of rock tunnel construction. The rock geological conditions are extremely complex and changeable. However, it is difficult to conduct accurate surveys before construction, which is the main reason for the slow construction progress and frequent accidents during the tunneling process. The ring-shaped confining pressure loading mechanism and the rock-breaking angle adjustment mechanism of the cutters are used to conduct tests on specific rock samples, which can truly simulate the rock-breaking process of the cutters in the construction of the rock roadheader, and detect the true rock performance of multiple cutters of the roadheader in the state of cru...

AI Technical Summary

Problems solved by technology

At present, the existing rock-breaking test equipment for rock boring machine tools cannot detect the real force state of the tools under annular confining pressure, and cannot adjust the tool angles of multiple tools synchronously for testing
