The invention discloses an elevator provided with an anti-falling mechanism. The elevator comprises a lower supporting part and a workbench arranged above the lower supporting part; a first sliding groove is formed in the lower supporting part; two first sliding blocks are glidingly connected in the first sliding groove; the two first sliding blocks are fixedly installed on the lower supporting part through hydraulic oil cylinders correspondingly; the top ends of the two first sliding blocks are rotationally connected with second crossed transmission rods correspondingly; the top ends of the two second crossed transmission rods are rotationally connected with first crossed transmission rods through rotating shafts correspondingly; and a second rotating ring is fixedly connected with a first fixing column through a first connecting rod. According to the elevator, with adoption of a rack self-locking limiting mechanism, the two first crossed transmission rods are clamped and limited, sothat self-locking protection can be carried out after power is lost in case of an accident; and with adoption of a linkage type gravity center shifting structure, the effects that the lower supportingpart slides up and down in a linkage manner and the pit rollover prevention effect is increased when a pit is encountered are achieved.

    本发明公开了一种具有防坠落机构的升降机,包括下支撑部以及下支撑部上方设置的工作台,所述下支撑部内开设有第一滑槽,所述第一滑槽内滑动连接有两个第一滑块,两个所述第一滑块分别通过液压油缸与下支撑部固定安装,两个所述第一滑块顶端均转动连接有第二交叉传动杆,两个所述第二交叉传动杆顶端分别通过转轴转动连接有第一交叉传动杆,所述第二转环通过第一连杆固定连接有第一固定柱。本发明中,由于采用齿条自锁限位机构,实现了两个第一交叉传动杆之间卡死限位,以便于在发生意外失去动力后进行自锁保护,又由于采用联动式重心偏移结构,实现了下支撑部上下联动滑动,在遇到坑地时增加防坑地侧翻的效果。
