Embodiment Construction

[0017] In order to make the purpose, technical solutions and points of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention;

[0018] Such as figure 1 As shown, before the construction starts, when the left top cylinder 14 and the right top cylinder 3 stretch the top shield 1, the left magneto-rheological damper 15 added on the side of the left top cylinder 14 and the right top cylinder Adding the right magnetorheological damper 2 to one side of the oil cylinder 3 also supports the top shield 1 at the same time. During the construction process, by controlling the magnitude of the coil current of the left magnetorheological damper 15 and the right magnetorheological damper 2, Change the viscosity of the magnetorheological fluid 26, and use the generated damping force to absorb the longitudinal vibration ...

Abstract

The invention provides a method of adding TBM (tunnel boring machine) support cylinder magnetorheological dampers, is intended mainly to solve the problem that the existing full-face hard rock tunneling machine vibrates during tunneling, and is intended to relieve or decrease the damage due to severe vibrations of a main unit during operating. According to the technical scheme, magnetorheologicaldampers are added respectively between a top shield and a main drive, between a left upper shield and the main drive, between a right upper shield and the main drive, between a left shield and the main drive, and between a right shield and the main drive, so that longitudinal and transverse vibrations generated by the main unit during construction can be relieved, tunneling stability of the main unit can be improved, and better structural reliability and longer life can be imparted to the main unit.

Description

technical field [0001] The invention belongs to the technical field of vibration control of mechanical structures, and in particular relates to a method for adding a magnetorheological damper of a supporting oil cylinder. Background technique [0002] Full-face hard rock excavation equipment TBM is a large and complex tunnel excavation equipment integrating machine, electricity, hydraulics and control. It works in long distances, large buried depths, and complex geological environments. There are many problems such as cracking and wear of the reducer, and the vibration problem of the TBM main engine is particularly serious. The current full-face hard rock excavation equipment TBM is located between the shield and the main drive and only has support equipment without a vibration reduction system. [0003] Magneto-rheological damper, as a new type of vibration reduction equipment, has the advantages of low energy consumption, large output, fast response speed, simple structur...
