The invention discloses a lift platform. The lift platform comprises a lift platform board, and a frame base mounted under the lift platform board. The lift platform is characterized in that the framebase is evenly provided with N screw lift components, a driving shaft component, and a transmission chain mechanism. The N screw lift components are arrange into arbitrary polygons, wherein N is a natural number greater or equal to three. Each of the screw lift components comprises a screw, a nut, and a screw support base. The driving shaft component comprises a driving motor, a driving shaft, adriving support base, and two bevel gears. When the lift platform is lifting, the distance between fulcrums is unchanged, thus the stability of the lift platform is unchanged. The lift platform has good stability, accurate lifting position of a lift platform surface, and large carrying capacity. The invention also discloses a driving method for the lift platform.

    本发明公开了一种升降平台,包括升降平台板以及位于该升降平台板下方的一个车架底座,其特征在于,所述车架底座上均布有N个螺杆升降组件、一个驱动轴组件和一个传动链机构,所述N个螺杆升降组件排列成任意多边形,其中N为大于等于三的自然数,每个螺杆升降组件均包括螺杆、螺母和螺杆支座;所述驱动轴组件包括驱动电机、驱动轴、驱动支座和两个伞齿轮。本发明的升降平台在升降过程中支点之间距离不发生变化,从而使升降平台升降过程中稳定度不会变化,稳定性好,平台面升降位置准确,且承载能力大。本发明还公开了一种升降平台的驱动方法。
