The invention relates to the related technical field of lifting platforms, in particular to a double-screw type automatic lifting trolley which comprises a base, two sets of lifting mechanisms are symmetrically arranged on the base, and the ends, away from the base, of the lifting mechanisms are connected with supporting plates; the supporting plate is driven by a large spiral structure fixedly installed on the base to ascend and descend. A bearing plate is fixedly installed on the supporting plate, a first overturning piece and a second overturning piece are symmetrically arranged along the side end of the bearing plate, and the first overturning piece and the second overturning piece are connected with the large spiral structure through a transmission piece arranged on the bearing plate; the supporting plate is lifted through a large spiral structure, large-stroke lifting of the supporting plate can be achieved even if a foundation pit is shallow, and when the supporting plate is lifted to the highest point of the stroke, the bearing plate can provide a larger contact area, so that the supporting plate is not prone to falling off, and the supporting plate is not prone to falling off when the supporting plate is lifted to the highest point of the stroke. Therefore, the stability of the lifting trolley is improved.

    本发明涉及升降平台相关技术领域,具体是一种双螺旋式自动升降台车,包括底座,所述底座上对称设置有两组升降机构,所述升降机构远离所述底座的一端连接有托板;所述托板由固定安装在所述底座上的大螺旋结构驱动升降;所述托板上固定安装有承载板,沿所述承载板的侧端分别对称设置有第一翻转件及第二翻转件,所述第一翻转件及所述第二翻转件通过设置在所述承载板上的传动件与所述大螺旋结构连接;所述第一翻转件包括第一翻转板及设置在所述第一翻转板底部的扩展件,本发明通过采用大螺旋结构实现托板的升降,使得基坑较浅也能实现托板大行程升降,且托板升高至行程最高点时,承载板可以提供更大的接触面积,从而增加升降台车的稳定性。
