The invention discloses a four-column type automobile lifting machine, which relates to the technical field of lifting machines, and comprises a lifting column body, the lifting column body comprises a supporting groove body, a lifting stand column and a lifting arm. The supporting groove body half covers the outer side of the lifting stand column. A power assembly is arranged at the bottom of the lifting stand column. The lifting arm is connected to the lifting stand column, and a first groove body is formed in the supporting groove body. A plurality of safety holes are formed in the first groove body; a safety assembly is arranged on the lifting stand column. The safety assembly comprises a movable bumper, a rolling assembly and a middle assembly; the rolling assembly is connected to the lifting stand column and can roll on the inner wall of the supporting groove body. When the descending speed of the lifting stand column is too high, the rolling assembly drives the middle assembly to act so as to drive the movable safety rod to penetrate into one safety hole, and therefore rapid descending of the lifting stand column is avoided, and safety is improved; the middle assembly and the rolling assembly are simple and ingenious in structure, and all actions depend on a mechanical structure, so that safety can be guaranteed in the abnormal descending process.

    本发明公开了一种四柱式汽车举升机,涉及举升机的技术领域,其包括举升柱本体;举升柱本体包括支撑槽体、举升立柱、举升臂;支撑槽体半罩设在举升立柱的外侧;举升立柱的底部设有动力组件;举升臂连接在举升立柱上支撑槽体内设有第一槽体;在第一槽体上设有多个保险孔;举升立柱上设有安全组件;安全组件包括移动保险杆、滚动组件和中间组件;滚动组件连接在举升立柱上且能够在支撑槽体内壁上滚动;举升立柱下降速度过快时,滚动组件驱使中间组件动作,以便带动移动保险杆穿设进其中一保险孔内,从而避免举升立柱的快速降落提高安全性;中间组件、滚动组件结构简单巧妙且动作全部依赖机械结构,从而能够在非正常下降过程中,保证安全。
