The invention discloses a lifting platform for theater stage speech. The lifting platform comprises a base, wherein a lifting frame is welded to the outer wall of the top of the base, an air cylinderis installed on the lifting frame, a box body is welded to the outer wall of the top of the lifting frame, a driving motor is installed on the inner wall of the bottom of the box body through bolts, an output shaft of the driving motor is coaxially sleeved with a first gear, a transmission shaft is arranged in the box body, the transmission shaft is coaxially sleeved with a second gear, a disc iswelded to the outer wall of the top end of the transmission shaft, annularly-distributed reinforcing columns are welded to the outer wall of the top of the disc, and the same standing circular truncated cone is welded to the outer walls of the top ends of the multiple reinforcing columns. According to the lifting platform, due to the fact that the effective tooth number of the second gear is about3.6 times that of the first gear, the standing circular truncated cone can intermittently rotate, the speed reduction effect of the speed reducer is matched, audiences in multiple directions can conveniently watch the standing circular truncated cone, and a certain watching time can be reserved for the audiences in the rotating process.
本发明公开了一种剧场舞台演讲用升降台，包括底座，所述底座的顶部外壁焊接有升降架，且升降架上安装有气缸，所述升降架的顶部外壁焊接有箱体，且箱体的底部内壁通过螺栓安装有驱动电机，所述驱动电机的输出轴上同轴套接有第一齿轮，所述箱体内设有传动轴，且传动轴上同轴套接有第二齿轮，所述传动轴的顶端外壁焊接有圆盘，且圆盘的顶部外壁焊接有环形分布的加强柱，多个所述加强柱的顶端外壁焊接有同一个站立圆台。本发明由于第二齿轮的有效齿数约为第一齿轮的有效齿数的3.6倍，所以站立圆台会做间歇性转动，并配合减速器的减速效果，不仅能够方便多个方位的观众进行观看，而且还能够在旋转的过程中给观众预留一定的观看时间。
