一种升降装置及使用该升降装置的舞台结构
摘要：
本发明涉及一种升降装置及使用该升降装置的舞台结构，其中升降装置包括用于连接作业平台的固定架，还包括导向架和链轮组件；链轮组件包括链轮和缠绕在链轮上的链条，链条一端固定连接所述固定架，另一端固定连接在导向架上；链轮可相对滑动和相对转动的设置在导向架上；还包括用于驱动所述链轮沿所述导向架升降、以使所述链条带动所述固定架升降的驱动装置，以实现作业平台的升降。本发明的升降装置，通过采用链轮和链条将油缸的运动行程放大，减小了升降装置的安装尺寸，并通过导靴和导轨进行导向，实现了作业平台的平稳升降。
摘要（英）：

The invention relates to a lifting device and a stage structure using the same. The lifting device comprises a fixing support for being connected with an operating platform, a guide frame, a chain wheel assembly and a drive unit, wherein, the chain wheel assembly comprises a chain wheel and a chain wound on the chain wheel, one end of the chain is fixedly connected with the fixing support, the other end of the chain is fixedly connected on the guide frame, and the chain wheel is arranged on the guide frame in relative slip and relative rotation manners; and the drive unit drives the chain wheel to rise and fall along the guide frame so that the chain drives the fixing support to rise and fall so as to realize lifting operation of the operating platform. The lifting device has the advantages that motion stroke of an oil cylinder is increased by means of the chain wheel and the chain, thus reducing installation size of the lifting device; and the operating platform can stably rise and fall under guidance of guide shoes and guide rails.
