摘要: 针对全断面硬岩掘进机(Tunnel boring machine, TBM)掘进中刀盘被困的现象,设计出一种新型的TBM刀盘驱动技术,主要特征是:正常掘进工况下采用变频电动机驱动,当刀盘被困时,脱困装置和变频电动机共同驱动.脱困装置由定速电动机和液体黏性离合器组成,液体黏性离合器一方面可以比例控制电动机的扭矩输出,另一方面可以允许定速电动机的输出轴和离合器的输出轴之间存在滑差,防止刀盘未转动时定速电动机发生堵转。通过计算分析可知:新型刀盘驱动的脱困性能相对于现有的驱动方式具有明显的提升。新型刀盘驱动的关键技术是液体黏性离合器的控制,需要分析离合器的温升特性,并基于此提出离合器的扭矩控制线路。为了实现扭矩按预定控制路线变化,对离合器的扭矩传递机理开展初步研究。新型刀盘驱动系统的仿真结果表明,该系统比现有驱动系统在脱困性能方面有大幅度提升。

Abstract: Aiming at developing an effective driving technology for tunnel boring machine(TBM) cutter-head ,which is often trapped during construction. The main features of new driving technology are: the driving system consists two kinds of driving devices, variable frequency motor driving device and breakout driving device.The breakout driving device consists of an AC asynchronism motor and a hydro-viscous driver(HVD). The calculating result shows: the new cutter-head driver has a significantly-improved breakout performance than the existing ones. The key technology of the new cutter-head driver is the control of the HVD. By analyzing the temperature characteristics of the HVD, based on which the route of the clutch torque control is set. To make sure that the drive torque change the route, torque transfer mechanism of HVD is then analyzed. The simulation results show that the new cutter-head driving system has a stronger breakout driving ability than the existing driving system.

Key words: breakout driving technology, HVD, tunnel boring machine(TBM)
