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... 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6150 kN·m提升至9225 kN·m。经现场验证:在TBM脱困使用低速挡掘进时,设备可在7000 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。 展开更多

Low-carbon Economy is a kind of economic developing mode which takes low energy consumption,low pollution and low discharge as its foundation. It is another important revolution of the human society after the agriculture civilization and industry civilization. It deals with various fields including low-carbon energy,low-carbon agriculture,low-carbon industry,low-carbon transportation and low-carbon life,etc. Among those,low-carbon transportation is one of the important contents. Since high speed railway uses electricity as driving force,it runs without discharging waste gas,and it is a kind of clean and green transportation with little dust and smoke black. Therefore,the study of the relationship between the high speed railway and low-carbon economy is becoming one of the important frontier problems that confronting the theoretic circle. With demonstration analysis and comparative analysis,this paper discusses the comparative advantages of high speed railway in terms of energy saving and environment protection,treatment of sound pollution,land saving and reduction of external cost(mainly pollution treatment cost) ,etc. compared with the other transportation modes and ordinary railway. Taking Beijing-Tianjin Intercity Railway as an example,the paper further demonstrates the distinctive advantages in respect of energy conservation and emission reduction. Besides,the paper also predicates the low-carbon effects after several high speed railways is put into operation in a few years. It is concluded that the development of high speed railways will meet the need of low-carbon economy and is significant for sustainable and steady development of economy and society. 展开更多
