The invention relates to a self-locking mechanism. The self-locking mechanism is suitable for a hydraulic lifting system. The self-locking mechanism comprises a slide way, a first sliding column, a second sliding column and an indexing air cylinder, wherein the first sliding column and the second sliding column are in sliding fit with the slide way, and the indexing air cylinder is used for driving the first sliding column and the second sliding column to slide on the slide way so as to enable the first sliding column and the second sliding column to be close to each other or far away from each other; the self-locking mechanism is arranged between a first guide rail and a second guide rail of the hydraulic lifting system, and the self-locking mechanism can be switched between a locking state and a releasing state; and in the locking state, the indexing air cylinder drives the first sliding column and the second sliding column to be far away from each other, and the far ends of the first sliding column and the second sliding column fall into moving paths of a first sliding block and a second sliding block respectively. According to the self-locking mechanism, it is guaranteed that the hydraulic lifting system is still in a stable state when breaking down, so that the overall safety performance of the hydraulic lifting system is improved.

    本发明涉及一种自锁机构,适用于液压升降系统。该自锁机构包括滑道、第一滑柱、第二滑柱和分度气缸,第一滑柱和第二滑柱与滑道滑动配合,分度气缸用于驱动第一滑柱和第二滑柱在滑道上滑动以使两者相互靠拢或远离;自锁机构设置在液压升降系统的第一导轨和第二导轨之间,自锁机构能够在锁定状态和释放状态下切换,在锁定状态下,分度气缸驱动第一滑柱和第二滑柱相互远离,并使第一滑柱和第二滑柱的远端分别落入第一滑块和第二滑块的移动路径上。本发明提出了一种自锁机构,保证液压升降系统在发生故障时仍处于稳定状态,提升液压升降系统的整体安全性能。
