Abstract

The invention provides a shield machine tool wear monitoring device and method based on the topography of the ballast piece. The mapping relationship between the hob structure parameters, engineering geological parameters, shield tunneling parameters, ballast piece topography parameters and temperature parameters and the hob wear amount in The relationship analysis results build a hob wear prediction system and set the hob wear alarm threshold. The present invention can predict the wear state of the hob in real time through the actual engineering geological parameters, the structural parameters of the hob, and the real-time driving parameters and ballast parameters, and provides an alarm function when the predicted wear state of the hob reaches the set threshold, and The accurate prediction of hob wear can be improved by closed-loop feedback adaptive adjustment according to different projects.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a shield hob wear monitoring device and method based on the shape of a ballast piece. Background technique [0002] With the wide application of tunnel boring machines at home and abroad, shield construction has gradually become a main construction method in tunnel construction. For shield construction, shield hob is the main rock breaking tool. It is suitable for various rock formations, pebble gravel formations and soft and hard composite formations, and is widely used in various roadheaders. [0003] Due to the uncertainty of the rock and the complexity of the stratum during the excavation process, the dynamics of the force change of the tool and the uncertainty of the tool wear form are caused. After a long time of rock cutting, the hob needs to be replaced due to abnormal wear or normal wear to a certain extent, which will inevitably affect the shield tunneling...
