The invention discloses a vehicle and a lifting oil cylinder thereof. The lifting oil cylinder comprises a cylinder barrel assembly and a piston rod assembly; the cylinder barrel assembly is fixedly provided with a first limiting mechanism; the piston rod assembly is fixedly provided with a second limiting mechanism which is used for moving along with the piston rod assembly and is matched with the first limiting mechanism; when the second limiting mechanism ascends along with the piston rod assembly, the first limiting mechanism supports and clamps the second limiting mechanism so as to prevent the second limiting mechanism from falling back; and by adopting the the lifting oil cylinder, the piston rod assembly can be prevented from falling due to faults, and the personal safety of maintenance personnel is guaranteed.
本发明公开了一种车辆及其举升油缸,举升油缸包括缸筒总成和活塞杆总成,所述缸筒总成固设有第一限位机构,所述活塞杆总成固设有用以跟随所述活塞杆总成运动、与所述第一限位机构配合的第二限位机构;当所述第二限位机构跟随所述活塞杆总成上升时,所述第一限位机构支撑并卡止所述第二限位机构以防止所述第二限位机构回落。上述举升油缸能够避免因故障导致活塞杆总成下落,保证了检修人员的人身安全。
