Abstract

The invention provides a synchronous detection test device for multi-item parameters of linear TBM hobs applied in the full-section hard-rock tunneling machine industry. The whole device consists of a self-counterforce frame, a regulate tool rest, an X-direction moving worktable, an X-direction linear guide rail, a Y-direction moving worktable, a Y-direction linear guide rail, an X-direction hydraulic cylinder, a rock sample, a hob, a four-rod guide mechanism, three-direction pressure sensors, a Z-direction hydraulic cylinder and the like, wherein the lateral movement direction of the rock sample is set as an X axis; the axial direction of the hob is set as a Y axis; the direction perpendicular to the surface of the rock sample is set as a Z axis; the rock sample is fixed on a trolley; the regulate tool rest is arranged on the four-rod guide mechanism; the X-direction moving worktable and the Y-direction moving worktable are arranged on a horizontal linear guide rail; the hob is arranged in a hob seat and is connected with the regulate tool rest through the three-direction pressure sensors; the rock sample is arranged and clamped on the X-direction moving worktable; and the three direction hydraulic cylinders are fixed with the fixed self-counterforce frame respectively. The device has the advantage of more precise function of simulating the process of breaking rocks through the hob, and is used for the synchronous detection of three-direction force, tool interval, penetration degree, wear degree, phase difference and other parameters of the hob in the states of linear paths and high-speed rotation of a plurality of hobs.

Description

Technical field: [0001] The invention relates to a multi-parameter synchronous detection test device of a linear TBM hob in the full-section hard rock roadheader industry. Background technique: [0002] The hob is the key part of the cutter head of the full-section hard rock roadheader. The arrangement and type selection of the hob on the cutter head directly determine the construction quality and efficiency of the full-face roadheader. Parameters such as cutter penetration, wear and cutting specific energy are the main parameters of the hob in the layout and selection of the cutter head of the roadheader. The multi-parameter synchronous detection test device of the TBM hob can complete the simultaneous measurement of the above parameters, thereby guiding the development and design of the full-face hard rock roadheader. At present, the existing hob test equipment cannot realize the synchronous detection under the condition of straight line trajectory and the synchronous det...

AI Technical Summary

Problems solved by technology

At present, the existing hob test equipment cannot realize the synchronous detection under the condition of straight line trajectory and the synchronous detection under the fast rotation state of the hob for parameters such as hob three-way force, knife spacing, penetration and phase difference, which makes the test data distorted , does not meet the actual rock crushing process of the full-face hard rock roadheader hob
