大型养路机械在委内瑞拉既有线施工作业中,因委内瑞拉早期铁路设计原因,曲线半径普遍偏小。而大养设备的主打设备捣固车和配碴车在小曲线半径线路作业中很容易掉道。对捣固车、配碴车作业时的受力情况进行了分析,找出掉道原因,并提出解决办法。 Large-scale maintenance machinery in Venezuela’s existing construction operations, due to Venezuela’s early railway design reasons, the curve radius is generally small. The large equipment main equipment tamper trucks and ballast trucks in the small radius of the curve line operation is easy off the road. For tamping cars, ballast car operations force situation was analyzed to find out the reasons for the loss, and propose solutions.
