Abstract

The invention belongs to the field of tunnel engineering equipment, and particularly relates to a TBM rock breaking test bed with linear / rotary dual modes. The problems that in the prior art, a TBM rock breaking test device is single in function, complex in structure and unreasonable in stress, and the actual working condition of a TBM cannot be truly simulated are solved. The technical scheme ofthe invention is as follows: the test bed comprises a base and a mounting frame; a loading device is mounted on the mounting frame, wherein the base comprises an upper test bed and a lower test bed; afirst horizontal hydraulic cylinder and a first rail are arranged on one side of the upper test bed, a linear soil box device is arranged on the first rail, a second horizontal hydraulic cylinder anda second rail are arranged on the lower test bed, a rotary soil box device is arranged on the second rail, and the first rail and the second rail are located below the loading device. The test bed ismore reasonable in structure, can truly simulate the actual working condition of the shield tunneling machine, and is suitable for rock breaking tests of the shield tunneling machine in a linear modeand a rotating mode.

Description

technical field [0001] The invention belongs to the field of tunnel engineering equipment, and in particular relates to a TBM rock-breaking test bench with linear / rotary dual modes. Background technique [0002] The shield machine is a large-scale high-tech construction equipment specially used for underground tunnel excavation. During the shield construction process, the research on tool wear is of great significance for the smooth excavation of the shield machine and the reduction of costs. Shield hobs and cutters are the main tools for cutterhead rock breaking. Hob cutter rings are vulnerable and consumable parts. When breaking rocks, they directly act on the excavation surface, which has the characteristics of harsh working environment, unstable working load, and Due to the characteristics of large impact, its wear and life directly affect the quality, efficiency and cost of excavation. Simultaneously, the cutter also has considerable wear and tear during the excavation...
