The invention belongs to the technical field of lifting platforms, and particularly relates to a heavy-load pneumatic synchronous lifting platform which comprises a bottom plate, two symmetrical driving air cylinders with the same size are mounted at the top of the bottom plate, and the output ends of the driving air cylinders are fixedly connected with first fixing flanges. The two driving air cylinders are used as power sources, larger lifting force can be provided for heavy-load objects on the surface of the jacking plate, meanwhile, the four sets of symmetrical limiting assemblies are arranged between the bottom plate and the jacking plate, and under the limiting supporting of the four guide rods on the bottom of the jacking plate, the lifting force can be greatly improved. The jacking plate can uniformly bear the weight of a heavy-load object, one side of the jacking plate can be prevented from inclining, meanwhile, when the guide rod and the jacking plate synchronously ascend and descend, a strip-shaped tooth groove in the surface of the guide rod can drive a circular gear to rotate, and therefore under mutual meshing between the circular gear and the strip-shaped tooth groove, the circular gear and the strip-shaped tooth groove can be driven to rotate. And high stability can be kept when the guide rods and the top plate synchronously ascend and descend.
本发明属于升降平台技术领域,尤其为重载型气动同步升降平台,包括底板,所述底板的顶部安装有两个大小相同且对称的驱动气缸,所述驱动气缸的输出端固定连接有第一固定法兰。本发明通过两个驱动气缸作为动力源,可为顶升板表面的重载物件提供更大的举升力,同时又在底板与顶升板之间设置了四组相互对称的限位组件,在四个导向杆对顶升板底部的限位支撑下,可以保证顶升板能够均匀承受重载物件的重量,可防止顶升板一侧发生倾斜,同时当导向杆与顶升板在做同步升降时,导向杆表面的条形齿槽会带动圆形齿轮转动,因此在圆形齿轮和条形齿槽之间的相互啮合下,可以保证导向杆和顶板在做同步升降时,保持较高的稳定。
