摘要
针对现有小型钢轨打磨机具在运输、搬运和作业过程中存在设计不合理、自动化程度低和质量重等诸多问题,文章采用砂轮周面打磨钢轨的方式研制锂电式轻便型钢轨打磨机具,研究内容包括打磨机具总体方案设计、机械结构设计、电气结构设计和钢轨打磨试验等,试验结果表明:为了保证钢轨表面获得较好的粗糙度值,建议小型打磨机具的砂轮采用较高的转速(最大线速度50 m/s)和较低的走行速度(≤2 km/h)。该机具的研制对提高小型打磨机具的自动化程度,降低人为因素对打磨质量的影响,减轻作业人员劳动强度具有重要意义。
In response to the various problems encountered during transportation,han-dling,and operation of existing small rail grinding machines,such as unreasonable de-sign,low automation level,and heavy mass,this article proposes the development of a lithium electric lightweight rail grinding machine that uses the peripheral surface of grind-ing wheel to grind the rail.It mainly includes the overall plan design of the grinding ma-chine,the mechanical structure design,the electrical structure design,and rail grinding experiments.The main conclusion shows that:in order to ensure a good surface roughness of the rail,it is recommended that the grinding wheels of the small grinding machine adopt high rotational speed(maximum linear speed of 50 m/s)and low traveling speed(<2 km/h).The new machine is significant to improve the automation level of small grinding machines,reduce the impact of human factors on grinding quality as well as the labor in-tensity of operators.
