摘要
为满足高速铁路建设需要,设计了客运专线可变跨轨道板龙门起重机。介绍了高速无碴轨道板系统以及轨道板铺设设备—龙门起重机的结构,分析了龙门起重机开式变量泵—变量马达调速原理,为开式液压行走系统在中等功率移动式起重设备上的应用提供了参考和借鉴。
To meet the needs of high-speed railway construction,we designed gantry crane with passenger dedicated line changeable span orbit plates.The article introduces high-speed track ballast-free plate system and the frame of board track laying equipment-gantry crane;also analyses opening variable pump-variable speed motors principle and provides a reference for the application of opening hydraulic walking system on medium-power mobile lifting equipment.
