Steel rail grinding wagon unit structure
The invention provides a steel rail grinding wagon unit structure which comprises a grinding wagon body, an abrasive belt grinding unit and three movement branch chains, all the movement branch chains are used for adjusting the position and grinding posture of the abrasive belt grinding unit, the abrasive belt grinding unit is used for grinding a steel rail, and the grinding wagon body is used for arranging and bearing all devices of the steel rail grinding wagon unit structure. Wherein the moving branch chain comprises a moving pair, a first rotating pair and a second rotating pair, the moving pair is provided with a fixed end and a telescopic end relatively moving along the fixed end, the fixed end is rotationally connected with the grinding wagon body through the first rotating pair, and the telescopic end is rotationally connected with the abrasive belt grinding unit through the second rotating pair. The three moving branch chains are arranged between the grinding wagon body and the abrasive belt grinding unit, so that the abrasive belt grinding unit is always kept in a stable state in the steel rail grinding process, the shaking condition existing in the working process is eliminated, the stability performance is improved, the grinding force of the abrasive belt grinding unit on the steel rail is uniform, and the grinding efficiency is improved. And the grinding efficiency and the grinding quality are improved.
本申请提供了一种钢轨打磨车单元结构，包括打磨车车体、砂带打磨单元和三个运动支链，各运动支链用于调节砂带打磨单元的位置和打磨姿态，砂带打磨单元用于打磨钢轨，打磨车车体用于设置及承载钢轨打磨车单元结构的各个装置；其中，运动支链包括移动副、第一转动副和第二转动副，移动副具有固定端和沿固定端相对移动的伸缩端，固定端通过第一转动副与打磨车车体转动连接，伸缩端通过第二转动副与砂带打磨单元转动连接。通过在打磨车车体与砂带打磨单元之间设置三个运动支链使砂带打磨单元在钢轨打磨过程中始终保持平稳状态，消除了工作过程中存在的抖动状况，增加了稳定性能，也使得砂带打磨单元对钢轨的打磨力均匀，提高了打磨效率和打磨质量。
