The invention discloses a double-hydraulic-cylinder lifting device and a control system thereof.The double-hydraulic-cylinder lifting device comprises a driving lifting cylinder mechanism and a driven lifting cylinder mechanism which are of the same structure, the driving lifting cylinder mechanism and the driven lifting cylinder mechanism each comprise a supporting frame and a mounting platform, and each supporting frame is provided with an upper mounting base and a lower mounting base; the upper mounting base and the lower mounting base are connected through a plurality of stand columns to form a frame structure. A hydraulic cylinder is mounted on the mounting platform; a piston rod of the hydraulic cylinder is in transmission connection with the grabbing mechanism; a plurality of telescopic guide rods are further arranged between the upper mounting seat and the lower mounting seat, a follow-up frame is arranged below the guide rods, and the guide rods can synchronously drive the follow-up frame to move up and down under the action of a hydraulic cylinder; the supporting frame is further provided with a displacement sensor used for monitoring the displacement amount of the piston rod of the hydraulic cylinder. The hydraulic cylinder can be controlled to stretch out and draw back, the driving hydraulic cylinder and the driven hydraulic cylinder can always keep synchronous movement, and stable lifting and descending actions of a load are completed.

    本发明公开了一种双液压缸举升装置及其控制系统,该装置包括两个结构相同的主动举升缸机构和从动举升缸机构,主动举升缸机构和从动举升缸机构均包括支撑框架和安装平台,支撑框架具有上安装座和下安装座,上安装座与下安装座之间通过若干根立柱连接形成框架结构;安装平台上安装有液压缸,液压缸的活塞杆与抓取机构传动连接;上安装座与下安装座之间还设置有若干根可伸缩的导向杆,导向杆的下方设置有随动架,导向杆可在液压缸的作用下同步带动随动架上下移动;支撑框架上还设置有用于监测液压缸活塞杆位移量的位移传感器。本发明可以实现对液压缸进行伸缩控制,能使主动液压缸和从动液压缸始终保持同步运动,完成负载的稳定举升和下降动作。
