摘　　要：由于受船舶运动的影响,船用大型液压升降机对升降平台的强度有特殊的要求,因此升降平台的重量很大。为了克服巨大的升降平台自重,驱动的液压缸尺寸较大,需要的压力油流量也很大。本文介绍的一种自重平衡液压系统,可抵消升降平台的重量,减小油缸的尺寸,达到在不增加系统压力油流量的情况下增加升降机的运行速度,同时还能回收升降平台和货物的重力势能。Due to the influence of the ship movement,the large hydraulic elevator installed on the ship has special requirements for the strength of the lifting platform,so the weight of the lifting platform is very large.In order to overcome the weight of the lifting platform,the size of the hydraulic cylinder is large,and the pressure oil flow is also large.The self-weight balancing system designed in this paper can offset the weight of the lifting platform,reduce the size of the cylinder,increase the elevator speed without increasing the pressure oil flow,and recover the gravitational potential of the lifting platform and cargo.
