The safety limiting assembly comprises a limiting rod located on one side of a supporting arm and a limiting block capable of being movably arranged on the limiting rod, the limiting rod is a lead screw capable of rotating around the axis of the limiting rod, the limiting block is matched with the lead screw, and the limiting rod can rotate around the axis of the limiting rod. The length of the lead screw is larger than the length of the sliding track of the supporting arm on the base. Two sets of safety limiting assemblies are arranged on the base side by side. On one hand, on the basis that the limiting block abuts against the end, sliding on the base, of the supporting arm, the length of the lead screw is larger than that of the sliding track of the supporting arm on the base, supporting arm unfolding limiting protection is formed, and the safety of the hydraulic elevator is improved; and on the other hand, rotation of the lead screw can be manually or automatically adjusted, especially abutting and attaching can be kept in an automatic adjusting mode, unfolding and folding of the supporting arm are assisted, full-automatic real-time protection is achieved, practicability is high, and the accident rate is reduced.

    本发明公开了液压升降机的安全限位组件及应急安全防护工艺,其组件包括位于支撑臂一侧的限位杆、能够活动的设置在限位杆上的限位块,其中限位杆为能够绕自身轴心方向转动的丝杆,限位块为与丝杆配合,且为在丝杆和限位槽上来回移动的螺母,丝杆的长度大于支撑臂在底座上滑动轨迹的长度;底座上并排设有两组安全限位组件。本发明一方面能够基于限位块抵触在支撑臂滑动在底座的端部、且丝杆的长度大于支撑臂在底座上滑动轨迹的长度以形成支撑臂展开限定保护,提高液压升降机的安全性;另一方面所丝杆的转动可以手动或自动调整,尤其是在自动调整模式下能够保持抵触贴合,不仅助力支撑臂展开和收拢,而且全自动实时保护,实用性强、降低事故率。
