The invention relates to the technical field of automobile maintenance equipment, and discloses a double-guarantee type automobile gantry lifting machine and a working method thereof. The reliability and the safety of the lifting machine are improved, and the personal safety of maintenance personnel is protected. The automobile gantry type lifting machine comprises a lifting machine body, a safety assembly, a synchronous driving assembly, a lead screw lifting assembly and a lifting frame. After starting, the chain type hydraulic lifting mechanism provides power, and the synchronous driving assembly receives the power to enable the connecting sliding seat to vertically slide along the stand column. A fixed seat and a shaft rod which are connected to the sliding seat drive a rotating drum to rotate, and power is transmitted to a lead screw lifting assembly through a gear in a transmission box, so that a bidirectional lead screw rotates. Rotation of the two-way lead screw enables the horizontal sliding base to slide along the cross beam, and then the lifting plate frame is driven by the connecting rod to ascend or descend along the stand column. The lifting frame and the lifting sliding frame are locked through the locking assembly, and it is ensured that the lifting plate frame and the lifting sliding frame move synchronously.

    本发明涉及汽车维修设备技术领域,公开了一种双重保障型汽车龙门举升机及其工作方法。旨在提高举升机的可靠性和安全性,保护维修人员的人身安全。该汽车龙门式举升机包括举升机本体、安全组件、同步驱动组件、丝杆升降组件和提拉框。启动后,链条式液压举升机构提供动力,同步驱动组件接收动力使连接滑座沿立柱垂直滑动。连接滑座上的固定座和轴杆带动转筒旋转,通过传动盒内的齿轮将动力传递至丝杆升降组件,使双向丝杆转动。双向丝杆的转动使水平滑座沿横梁滑动,进而通过连接杆带动升降板架沿立柱上升或下降。锁固组件将提拉框与举升滑架锁紧,确保升降板架与举升滑架同步运动。
