The invention provides an automatic control jack, and relates to the technical field of jacks. The automatic control jack comprises a jack base and a hydraulic oil supply device, wherein an oil supply pipeline is connected between the jack base and the hydraulic oil supply device, a flow regulating valve corresponding to the oil supply pipeline is installed in the center of the front end of the jack base, lifting hydraulic cylinders are fixedly connected to the corners of the center of the jack base, the top ends of piston rods of the multiple lifting hydraulic cylinders are fixedly connected with a fixing plate, a mounting base is fixedly connected to the top of the fixing plate, a plurality of fixing screws corresponding to the fixing plate are fixedly connected to the peripheral side of the mounting base, and a top supporting plate is arranged at the top of the mounting base. Through the design of the jack, the jacking hydraulic cylinder, the hydraulic oil supply device, an elastic reset mechanism and an automatic control mechanism, after a heavy object is placed on the supporting plate, the supporting plate can automatically trigger a switch after being stressed, and therefore the jack can automatically complete jacking and lifting of the heavy object.

    本发明提供一种自动控制起重器,涉及起重器技术领域。该种自动控制起重器,包括起重器底座和液压供油装置,所述起重器底座和液压供油装置之间连接有供油管路,所述起重器底座前端的中心安装有与供油管路相对应的流量调节阀,所述起重器底座中心的边角处均固定连接有升降液压缸,多个所述升降液压缸活塞杆的顶端固定连接有固定板;所述固定板的顶部固定连接有安装底座,所述安装底座的周侧固定连接有多个与固定板相对应的固定螺钉,所述安装底座的顶部设置有顶支撑板。通过设计起重器、顶升液压缸、液压供油装置、弹性复位机构以及自动控制机构,当重物放置在支撑板上后,支撑板受力后会自动触发开关,从而使起重器可以自动完成重物的顶升起重。
