动车组车体底部距轨面较低,走行部底架和转向架间的结构空间狭小,一旦发生动车组在整体道床上脱轨事故,国内现有任何一种复轨器都不能直接安装、拉复作业。为此研制适用动车组在整体道床脱轨拉复的复轨器,在减少对行车设备损伤的前提下进行快速拉复,以缩短救援起复作业时间,确保铁路运输安全畅通。
At the bottom of the carbody, the bottom of the car body is lower than the rail surface, and the structural space between the undercarriage and the bogie of the traveling department is small. In the event of a derailment of the motor train unit on the integral track bed, any existing railroad tracker can not be directly installed and pulled Complex homework. For this reason, the research and application of the compound rail tracker for railroad track derailment and recovery in the whole railroad bed will be carried out in a short time under the premise of reducing the damage to the traveling equipment so as to shorten the time for rescue and recovery operations and ensure the safe and smooth transportation of the railway.
