摘要

高黎贡山隧道出口段采用2台敞开式TBM分别在主洞和平导洞施工，由于地质条件复杂，TBM经常遇到刀盘脱困转矩不足导致设备卡机的情况。为提高刀盘驱动系统脱困转矩，满足TBM在破碎围岩条件下掘进的需要，对彩云1号TBM主驱动系统安装双速减速机的技术改造进行研究。双速减速机安装在TBM主电机和减速机之间，高、低速模式下减速比分别为1.00和1.47，可通过手柄直接进行模式切换，具有切换方便的特点; 在低速模式下，可将设备脱困转矩由6 150 kN·m提升至9 225 kN·m。经现场验证：在TBM脱困使用低速挡掘进时，设备可在7 000 kN·m转矩下持续掘进，说明在TBM上安装双速减速机可大大提高敞开式TBM在软弱破碎围岩地质条件下的脱困能力。

Abstract

The exit sections of the main and pilot tunnels of the Gaoligongshan tunnel are constructed using two different open tunnel boring machines (TBMs), and owing to the complex geologies and insufficient cutterhead torque, the TBMs are often jammed. Consequently, to improve the cutterhead torque for TBM jam release, a dualspeed reducer is arranged in the main drive system of TBM Caiyun #1. The speed reducers are installed between the main motor and the speed reducer. The speed reduction ratios in high and lowspeed modes are 1 and 1.47, respectively, and can be switched directly and easily. In the lowspeed mode, the jam release torque for the device can be increased from 6 150 to 9 225 kN·m. The field test shows that when the TBM is driven at low speed, the equipment can continue to drive under a torque of 7 000 kN·m, which significantly improves the jam release capacity of the equipment. The practical results indicate that by installing the dualspeed reducer on a TBM, the TBM jam release capacity can be significantly improved, providing a reference for TBM design in similar geologies.

Key words： Gaoligongshan tunnel; TBM jam release; dualspeed reducer; high and low speed; cutterhead torque; cutterhead rotation speed
