Embodiment 2

[0041] The other implementations of this embodiment are the same as in Embodiment 1, the geological condition is 60% soft soil, the excavation process of the hydraulic propulsion cylinder 11 is divided into five groups, and only the hydraulic oil in the hydraulic mechanism 4 needs to be fully unloaded, by changing the hydraulic propulsion cylinder 11 and For the quick oil joint connection between the hydraulic mechanisms 4, the grouping was changed into five groups, and then the steps of Example 1 were repeated for testing.

Embodiment 3

[0043] The other implementations of this embodiment are the same as in Embodiment 1. The geological conditions are changed from 60% soft soil to 40% soft soil during the excavation process. Taking the hydraulic propulsion cylinder 11 as an example in four groups, in the process of steady propulsion, it can be adjusted The proportional overflow valve of the hydraulic mechanism 4 is used to change the pressure of the hydraulic loading cylinder 23, thereby increasing the bending moment, and realizing the sudden change of the address condition in the process of simulating the excavation.

[0044] This test device can simulate the excavation process of different groups of hydraulic propulsion cylinders with constant geological conditions, the excavation process of the same group of propulsion cylinders with constant geological conditions, the excavation process of different groups with sudden changes in the same geological conditions, and the same sudden change in different geologica...

Description

technical field [0001] The invention relates to a device in the technical field of tunnel engineering, in particular to a test device for force transmission characteristics of a tunneling machine. Background technique [0002] In real working conditions, when the shield tunneling machine is excavating, the geological layer will change abruptly. Sudden geological changes will cause the shield tunneling machine to stall, the main shaft will break, etc. In order to avoid the above working conditions in the tunneling process of the shield tunneling machine under different geological conditions, it is necessary to study its force transmission characteristics, and From this point of view, a compliance plan is proposed. [0003] In order to study the force transfer characteristics of the tunneling machine, the tunneling process must be simulated and restored. To study the force transmission characteristics of the roadheader during the tunneling process, it is necessary to monitor...
