The invention discloses a movable lifting machine used for car repair. The movable lifting machine comprises two lifting bases, wherein U-shaped slots are formed inside the two lifting bases; inner walls of the U-shaped slots are in sliding connection to U-shaped dual-tooth racks; first gears are engaged with upper side tooth slots of the U-shaped dual-tooth racks; the outer walls of the two sidesof each first gear are connected to extrusion pieces through bolts; the lower sides of the U-shaped dual-tooth racks are engaged with second gears; and centers of the second gears are connected to rotary shafts through bolts. The movable lifting machine can achieve certain supporting effect for a dropping car, prevents the perpendicular dropping car from injuring repair staff below, improves an integral safety coefficient of the lifting machine, can avoid a condition that the car drops again due to insufficient elastic force of a return spring, can conveniently regulate the position, is beneficial for repairing different positions of the car, can be convenient for getting tools by the repair staff, and improves check and repair efficiency of the car.

    本发明公开了一种用于汽车维修的可移动举升机,包括两个举升座,两个所述举升座的内部均开设有U型槽,且U型槽的内壁滑动连接有U型双齿架,所述U型双齿架的上侧齿槽啮合有第一齿轮,且第一齿轮的两侧外壁通过螺栓连接有挤压片,所述U型双齿架的下侧齿槽啮合有第二齿轮,且第二齿轮的中心通过螺栓连接有转轴。本发明能够对下落的汽车起到一定的支撑作用,避免汽车垂直降落对下方的维修人员造成砸伤,提高举升机整体的安全系数,能够避免复位弹簧的弹力不足而出现汽车再次掉落的情况,能够便于对举升机位置的调节,利于对汽车不同位置的维修,能够便于维修人员对工具的拿取,提高对汽车的检查维修效率。
