The invention relates to the technical field of multi-stage lifting tables, in particular to a synchronous lifting device. According to the technical scheme, the device comprises a fixing frame, the fixing frame is provided with a first-stage frame, the first-stage frame is connected with a second-stage frame in a sliding mode, the first-stage frame and the second-stage frame are connected through a chain system, a guide wheel set C and a guide wheel set D are installed on one side of the first-stage frame, and a guide wheel set A and a guide wheel set B are installed on one side of the second-stage frame; first wire frames are hinged to the two sides of the first-stage frame, the other ends of the first wire frames are hinged to the second-stage frame, second wire frames are hinged to the two sides of the second-stage frame and used for installing the multi-stage frame, one side of the fixing frame is connected with a servo motor through bolts, and an output shaft of the servo motor is fixedly connected with a transmission chain wheel. And the transmission chain wheel is in transmission connection with a chain system mounted on the first-stage frame and the second-stage frame through a driving chain. The lifting device is small in occupied space after being descended, high in lifting stroke, capable of lifting in an unbalanced loading mode and wide in application in the stage deduction industry.

    本发明涉及多级升降台技术领域,尤其涉及一种同步升降装置。其技术方案包括:固定架,所述固定架安装有一级架,所述一级架滑动连接有二级架,且一级架和二级架通过链条系统连接,所述一级架的一侧安装有导轮组C和导轮组D,所述二级架的一侧安装有导轮组A和导轮组B,所述一级架的两侧均铰接有线架一,所述线架一的另一端与二级架铰接,所述二级架的两侧均铰接有线架二用于安装多级架,所述固定架的一侧通过螺栓连接有伺服电机,所述伺服电机的输出轴固定连接有传动链轮,所述传动链轮通过驱动链条与安装在一级架和二级架上的链条系统传动连接。本发明在降下后占地空间小,升降行程高,可偏载载重升降,在舞台演绎行业应用广泛。
