百米长尺轨收集小车和升降梁不同步问题的分析及改进

THE SPEED DIFFERENCE ANALYSIS AND IMPROVEMENT OF THE 100 METERS LONG RAIL COLLECTION BED TRANSPORTATION CAR AND THE LIFTING BEAM

针对目前我厂百米长尺轨收集台架拉钢小车和升降梁不同步问题的原因进行分析,阐述了液压马达的结构特点和工作原理,且将系统中所用的几种液压阀工作原理进行详细分析,比较其工作特性,提出改进措施。

The paper analyze the speed difference of the 100 meters long rail collection bed transpor- tation car and the lifting beam, and illustrates structure of the Hydraulic motor, introduce the work princi- ple of the hydraulic motor. Explain way of working the valves in the control system, Draw a comparison work character of the valves. Put forward modification measures about the Hydraulic control system.
