The invention provides a full-hydraulic-drive wide and thick plate flattening machine feeding lifting platform, which belongs to the technical field of large-scale wide and thick plate finishing, and comprises a bed board, a carrier roller device, a wide and thick plate and a lifting device, wherein the carrier roller device comprises a carrier roller and a carrier roller frame, the lifting device comprises a lifting mechanism and a hydraulic system, and the lifting mechanism and the hydraulic system are driven to achieve the lifting function; according to the device, the horizontal movement of the piston rod of the three-containing-cavity hydraulic cylinder is converted into the up-down movement of the lifting device in a scissor fork structure mode, and in addition, stable, reliable and accurate operation of the lifting platform in the working process is achieved through cooperative control of a position closed loop and a pressure closed loop; the combination of the two effectively solves the problems of poor synchronism of mechanical hard connection and difficulty in four-cylinder synchronous control.

    本发明提供的一种全液压驱动的宽厚板压平机上料升降平台,属于大型宽厚板精整技术领域,其包括有铺板、托辊装置、宽厚板、升降装置;其中托辊装置包括有托辊、托辊架,升降装置包括有升降机构及液压系统,升降机构与液压系统驱动来实现升降功能;本装置通过剪刀叉结构形式将三容腔液压缸活塞杆的水平运动转化为升降装置的上下运动,另外位置闭环与压力闭环的协同控制实现了升降平台工作过程的稳定可靠精确运行,两者结合有效解决了机械硬连接同步性较差和四缸同步控制难的问题。
