摘要

钢轨打磨车通过牵引机构将动力传递至车体底部的打磨装置，使其沿钢轨进行走行作业和打磨作业。现有牵引机构多采用带角度的斜拉式安装，针对这种牵引机构使用过程中存在的问题，提出了一种竖直式牵引机构。以某型钢轨打磨车为例，对使用竖直式牵引机构的打磨车进行牵引力计算和静力学分析，同时对打磨装置进行动力学特性计算。通过分析计算得出，竖直式牵引机构的力学特性能够满足打磨装置的使用需求，使用竖直式牵引机构的打磨装置具有良好的平稳性和曲线通过性能，避免了传统斜拉式牵引机构所存在的问题，具有较好的应用前景。

Abstract

The rail grinding vehicle transmits the power to the grinding device at the bottom of the vehicle body through the traction mechanism, so that it can run and grind along the rail. For rail grinding device, the traditional installation method of traction mechanism was cable-stayed traction with angle. In view of the problems of this type of traction, the structural form of vertical traction mechanism was creatively proposed in this paper. Taking a rail grinding vehicle as an example, the traction force, the static analysis of the traction mechanism and the dynamic characteristics of the grinding device were analyzed. Through the analysis and calculation,the mechanical properties of the vertical traction mechanism can meet the requirements of the grinding device, and the grinding device with this type of traction had good stability and curving performance. The vertical traction mechanism of grinding device can avoid the problems of traditional cable-stayed traction mechanism and had a good application prospect.
