The invention belongs to the technical field of railway locomotive overhauling, and discloses a lifting device and a car lifting jack. The lifting device comprises a bracket, two supporting frames, a lifting driving assembly and limiting assemblies, the bracket comprises a frame body and two roller sets, the two roller sets are rotationally arranged on the two opposite sides of the frame body, each roller set comprises a plurality of rollers, and guide channels are defined by the rollers on the side surfaces of the frame body; the two supporting frames are arranged in the two guide channels in a penetrating mode in a one-to-one correspondence mode; the bracket is fixedly connected to the output end of the lifting driving assembly, and the lifting driving assembly can drive the bracket to move along the guide channels; and the limiting assemblies are fixedly connected to the supporting frames, stretch into the guide channels and abut against the rollers, and the abutting faces of the limiting assemblies and the rollers gradually get close to the supporting frames from the ends deviating from the frame body to the ends facing the frame body. According to the lifting device, the restraining capacity on movement of the bracket can be improved, the problems of yawing of lifting of the bracket and stress unbalance loading of the lifting driving assembly are solved, and the service life of the lifting device is prolonged.

    本发明属于铁道机车检修技术领域,公开了一种升降装置及架车机,包括托架、两个支撑架、升降驱动组件和限位组件,托架包括架体和两个滚轮组,两个滚轮组转动设置于架体相对的两侧,每个滚轮组包括多个滚轮,多个滚轮在架体的侧面围设形成一个导向通道;两个支撑架一一对应地穿设于两个导向通道中;托架固连于升降驱动组件的输出端,升降驱动组件能够驱动托架沿导向通道运动;限位组件固连于支撑架,伸入导向通道中,抵靠于滚轮,自背离架体的一端到朝向架体的一端,限位组件与滚轮的抵靠面逐渐靠近支撑架。该升降装置能够提高对托架运动的约束能力,消除托架升降的横摆和升降驱动组件的受力偏载等问题,延长升降装置的使用寿命。
