The invention provides a lifting platform truck loading device based on multi-cylinder jacking, which is applied to a transportation flat car and comprises a cargo loading platform, a lifting platform, a lifting platform and a lifting platform, the supporting structure is movably connected with the cargo carrying platform and used for supporting the cargo carrying platform and fixing the supporting leg oil cylinder; the supporting leg oil cylinders are symmetrically arranged on the two sides of the supporting structure and used for achieving lifting of the cargo carrying platform. The hydraulic station is connected with the cargo carrying platform and used for providing pressure for the supporting leg oil cylinders and controlling the oil cylinders to ascend and descend. The technical problems that in the prior art, under the condition that the rigidity of a lifting structure is poor, the influence of uneven ground cannot be overcome, all oil cylinders are independently controlled through a proportional valve and a displacement sensor, and synchronous jacking is achieved through closed-loop control are solved.
本发明提供一种基于多缸顶升的升降平台装车装置,应用于运输平板车上,所述装置包括:载货平台,用于装载货物;支撑结构,与载货平台活动性相连,用于支撑载货平台,固定支腿油缸;若干支腿油缸,对称设置于支撑结构两侧,用于实现载货平台升降;液压站,与载货平台相连,用于为支腿油缸提供压力,控制油缸升降。解决现有技术无法在升降结构刚性差的情况下,克服地面不平的影响,采用“比例阀+位移传感器”单独控制各条油缸,闭环控制,实现同步顶升的技术问题。
