The invention relates to the technical field of hydraulic lifting operation platforms, in particular to an anti-falling device for a hydraulic lifting operation platform, and aims to solve the problem that a bearing platform suddenly falls back due to failure of a hydraulic telescopic rod, an auxiliary limiting part synchronously started with a lifting driving part elastically limits a connecting round rod I; the safety problem caused by sudden falling of the bearing platform is avoided; in the unfolding process of the folding piece, as the angle between the first connecting supporting rod and the movable machine body is gradually increased, the auxiliary supporting part located below the first connecting supporting rod can be jacked up under the action of the elastic restoring force of the auxiliary supporting part, and the first connecting supporting rod is limited and supported within a certain range; the bearing platform is prevented from falling back due to sudden unloading of the hydraulic telescopic rod; through double buffering and limiting of the auxiliary limiting part and the auxiliary supporting part, impact force generated by sudden falling of the bearing platform is reduced, and safety of workers and articles is ensured.
本发明涉及液压升降作业平台技术领域,特别涉及一种液压升降作业平台防回落装置,若液压伸缩杆出现故障导致承载平台突然回落,则跟升降驱动件同步启动的辅助限位部就会对连接圆杆一进行弹性限位,以避免承载平台突然回落导致的安全问题;折叠件展开的过程中,随着连接支撑杆一与移动机体之间的角度逐渐增大,位于连接支撑杆一下方的辅助支撑部会在自身的弹性回复力作用下顶升起,对连接支撑杆一进行一定范围的限位支撑,以防止因液压伸缩杆的突然卸力导致的承载平台回落;通过辅助限位部与辅助支撑部的双重缓冲限位,减小承载平台突然回落产生的冲击力,确保工作人员与物品的安全。
