The invention relates to the field of electro-hydraulic servo lifting systems, in particular to an electric control hydraulic lifting bearing system with a double-valve self-locking protection function. The device comprises a rack, a bearing seat bracket, a chain, a tray, a lifting lug, a hydraulic cylinder, a rack base, a photoelectric sensor, a chain wheel, a deep groove ball bearing, a bearing seat and a hydraulic cylinder link frame, the rack and the rack base play a supporting role; the hydraulic cylinder is controlled by an electro-hydraulic servo valve to provide power for the mechanism; the bearing seat rack is used for fixing the bearing seat and is connected with the bearing seat through bolts and nuts; the chain is meshed with the chain wheel to drive the tray fixed with the chain through the lifting lug to lift; the photoelectric sensor is used for detecting people and articles and protecting the safety of people, articles and properties; the two two-position two-way electromagnetic directional valves are adopted, the self-locking protection function of a hydraulic oil way is achieved, compared with other lifting systems, the lifting system can be emergently stopped at any position, and the device is simple in structure, convenient to operate and high in safety.

    本发明涉及电液伺服举升系统领域,具体为一种具有双阀自锁保护功能的电控液压举升承载系统。其中包括机架、轴承座支架、链条、托盘、吊耳、液压缸、机架底座、光电传感器、链轮、深沟球轴承、轴承座、液压缸链接架;所述机架与机架底座起到支撑作用;所述液压缸由电液伺服阀控制为机构提供动力;所述轴承座机架用来固定轴承座并采用螺栓和螺母进行连接;所述链条与链轮相啮合带动通过吊耳与链条固定的托盘升降;所述光电传感器用来检测人与物品,保护人、物与财产的安全;本发明采用两个二位二通电磁换向阀,实现液压油路的自锁保护功能,相对于其他举升系统,可以解决将举升系统紧急停在任意位置,该设备结构简单,操作方便且安全性高。
