目前,我国铁路线路养护所用的电动捣固棒存在着结构大、自身设备重、作业效率低、易漏电等缺点,已无法满足铁路行车密度高、列车速度快、运载重型化的发展需求。为了有效地利用列车运行间隔时间进行捣固作业,而又能最大程度地确保作业中的安全性,急需开发出一种由单人独立操作,不需要任何附属动力设备的新型便携式内燃捣固机。基于此种社会需求,本研究研制出了一种新型高效、安全可靠、轻便易操作的便携式内燃捣固机(简称BDG—Ⅰ型),其主要贡献为：1根据国内对新型捣固机的需求,自主设计并研制出一种轻便、易携带、单人操作的BDG—Ⅰ型新型内燃捣固机,经有关性能测试,各项性能指标均超出或达到了原机型的技术要求；2运用振动原理进行了捣固机的振动设计,并建立出BDG—Ⅰ型捣固机振动装置相应的数学模型,实验检验结果证实了其数学模型的合理性；3基于可靠性理论,本文分别建立出捣固机锥齿轮传动和振动装置的可靠度模型,并对新型捣固机系统的可靠性进行了分析,为确保BDG—Ⅰ型捣固机的性能提供了理论支撑。本研究是上海铁路局科委2002年5月科研立项项目——BDG—Ⅰ型便携式内燃捣固机研制的重要组成部分。该项目由上海分局和苏州铁路机械学校共同完成,并于2003年2月通过上海铁路分局新产品鉴定(上铁分局技验字20号)。该新产品已被郑州铁路分局等几个单位定购并直接应用于我国铁路线路养护,必将产生良好的经济和社会效益。
【英文摘要】There are some weaknesses in the electromotive tamping machine used in native railway, such as bigger and heavier, inefficient and leakage of electricity. It can’t fit well in with railway’s requirement of high running density, increased speed and heavy load. In order to vibrate effectively at the interval of running trains and ensure the safety of work, a new portable tamping machine that does not require attached power equipment and is operated by single man is needed. Based on this requirement, We have invented a new, efficient, safe and portable internal combustion blast tamping machine.The primary contributions of this paper are:1. Based on the native requirement of the tamping machine, We have designed and invented a new portable internal combustion blast tamping machine. It proved that many index of new machine is superior to that of the old.2. According to vibration theory, We had set up a mathematics model of vibrator. The result of experiment proves the correctness of mathematics model.3. Based on the theory of reliability, this paper have built the model of reliability of cone gear drive and shaker unit and analysed systemic reliability degree. This provided theoretical support for the BDG-I tamping machine.This paper is a important part of the project of the invention of the BDG-I tamping machine established by shanghai railway station’s scientific committee in May 2002 that was completed by Shanghai railway substation and Suzhou railway machinery school. In February 2003, Shanghai railway scientific committee appraised the new product. Now this product have been used by Zhengzhou railway substation etc and bring good economic and societal benefit.
