A high-safety large-tonnage electric hydraulic lifting platform comprises a balance lifting mechanism, a linkage extension reinforced supporting mechanism and a double-self-locking mechanism. The balance lifting mechanism comprises a cross supporting rod, a base and a bracket, the upper end of the cross supporting rod is slidably connected with the bracket, and the lower end is slidably connected with the base. The linkage extension reinforced support mechanism comprises a transmission device, an extension plate and a side bracket; the two extension plates are mounted in the base in a sliding manner, and are driven by a transmission device to synchronously move in the same direction or opposite directions; the bottoms of the side brackets are rotationally connected to two ends of the extension plate; the two double self-locking mechanisms are symmetrically mounted on the side bracket in a sliding manner; in the working process, the stress point is located in the center, the stability of equipment is improved, meanwhile, a double-self-locking mechanism is further arranged, the equipment can be locked in time under the condition that power cannot be normally provided for the equipment when the hydraulic cylinder explodes or breaks down, and therefore dangers are avoided, and the safety of the equipment is improved.
一种高安全性的大吨位电动液压升降平台,包括平衡升降机构、联动延伸加强支护机构和双重自锁机构;平衡升降机构包括交叉支撑杆、底座和托架,交叉支撑架上端与托架滑动连接,下端与底座滑动连接;联动延伸加强支护机构包括传动装置、延伸板和侧支架;延伸板有两个,滑动安装在所述底座内部,并通过传动装置驱动进行同步相向或相反运动;侧支架底部转动连接在延伸板的两端;双重自锁机构有两个,对称滑动安装在侧支架上;本发明在工作工程中受力点在中心处,提高了设备的稳固性,同时还设有双重自锁机构,在液压缸发生爆缸或者故障无法正常为设备提供动力的情况下,能够及时对设备锁死,从而避免危险的发生,提高设备的安全性。
