The invention relates to the technical field of lifting appliances, in particular to a lifting appliance and method for subway track laying, the lifting appliance comprises a portal frame, a clamp assembly comprises a horizontally placed X-shaped movable frame, and suspension shafts are arranged at the four ends of the X-shaped movable frame; handle frames are arranged on the sides, away from the steel rails, of the side clamping plates, telescopic pieces are arranged on the two sides of each handle frame, and rotating sleeves are fixed to one ends of the telescopic pieces; positioning balls are arranged on the surface, close to the handle frame, of the transverse plate; the device has the beneficial effects that the handle frame is pushed to be close to the side clamping plates until the handle frame crosses the middle point between the two suspension shafts, at the moment, the handle frame is blocked by the side clamping plates, the telescopic piece is in a compressed state, the telescopic piece provides pushing force to enable the two suspension shafts to be away from each other all the time, and therefore the two side clamping plates can be close to each other all the time; on the contrary, the handle frame is pulled to be away from the side clamping plate, the side clamping plate can be easily separated from the steel rail, and therefore the device can have the functions of stable clamping and easy unfolding.

    本发明涉及吊具技术领域,具体为一种用于地铁铺轨的起升吊具及方法,包括门架,夹具组件包括水平放置的X型活动架,X型活动架的四端均设置有悬吊轴;侧夹板远离钢轨的一侧设置有把手架,把手架的两侧均设置有伸缩件,伸缩件的一端固定有旋转套;横板靠近把手架的表面设置有定位球;有益效果为:通过推动把手架靠近侧夹板、直至把手架越过两个悬吊轴之间的中点,此时把手架受到侧夹板阻挡、伸缩件处于受压缩状态,伸缩件提供推力使得两个悬吊轴始终相互远离,因此两个侧夹板能够始终相互靠近,实现对钢轨的稳定夹紧,反之,拉动把手架远离侧夹板,能够轻松将侧夹板与钢轨脱离,因此本装置能够兼顾稳定夹持和易于展开的功能。
