The invention relates a lifting machine. The single lifting machine comprises a bottom plate, a top plate, a hinge frame, a supporting oil cylinder and a power assisting arm. The hinge frame is arranged between the bottom plate and the top plate, a safety lock is arranged beside the supporting oil cylinder and comprises a lock rod, a buckle and a clamping ring. The lock rod is sleeved with the clamping ring, the clamping ring is connected with a piston rod of the supporting oil cylinder, and the buckle is arranged at the front portion of the clamping ring. The buckle is hinged to the clamping ring through a rotating shaft, a one-way return air cylinder is arranged at the rear portion of the clamping ring, a piston rod of the one-way return air cylinder corresponds to the buckle, and the buckle is clamped into a clamping groove of the lock rod under the gravity of the buckle. After a piston rod of the supporting oil cylinder extends and the height of the hinge frame is determined, the safety lock plays a role in reinforcing the hinge frame, and the situation that when the oil pressure of the supporting oil cylinder is unstable, a support of the hinge frame rapidly falls off, and an automobile falls off is avoided.

    本发明涉及举升机,单台举升机包括底板、顶板、铰接架、支撑油缸、助力臂,底板、顶板之间设有铰接架,支撑油缸旁设有安全锁,所述安全锁包括锁杆、卡扣、卡环,卡环套在锁杆上,卡环与支撑油缸的活塞杆连接,卡环前部设有卡扣,卡扣与卡环通过转轴铰接,卡环后部设有单程回位气缸,单程回位气缸的活塞杆对应卡扣,卡扣在自身重力下,卡扣卡入锁杆的卡槽中。本发明当支撑油缸的活塞杆伸长,铰接架确定高度后,安全锁对铰接架起到加固作用,避免支撑油缸的油压不稳定时,铰接架的支撑迅速掉落,造成汽车脱落。
