The invention provides a scissor-type lifting platform and a method, relates to the field of lifting platforms, and aims to solve the problem of instability caused by accumulation of rotation position gaps of a current multi-stage scissor-type structure, two oppositely mounted tapered roller bearings are adjusted by using an adjusting nut and an end, inner rings of the two tapered roller bearings are pushed to move together, and the stability of the scissor-type lifting platform is improved. Meanwhile, the gap between the inner rings and the outer rings of the two tapered roller bearings matched with the outer shear fork is changed, the gap is gradually reduced until no shaking gap exists, the accumulated gap after the multi-stage shear fork structure is stacked is reduced, and the stability of the shear fork type lifting platform is improved.
本发明提供一种剪叉式升降平台及方法,涉及升降平台领域,针对目前多级剪叉结构因转动位置间隙累积导致不稳定性的问题,利用调节螺母和端头对相反安装的两个圆锥滚子轴承进行调节,推动两个圆锥滚子轴承的内圈共同移动,同时改变外剪叉配合的两个圆锥滚子轴承的内圈和外圈的间隙,逐渐缩小其间隙直至无晃动间隙,减小多级剪叉结构叠加后的累积间隙,提高剪叉式升降平台的稳定性。
