The invention relates to the technical field of lifting equipment, in particular to a lifter with a movable bearing platform. The lifter comprises a bottom plate, wherein four supporting cylinders areconnected to the outer wall of the top of the bottom plate through bolts, lifting cylinders are movably inserted into the four supporting cylinders respectively, middle cylinders are movably insertedinto the four lifting cylinders respectively, inner cylinders are movably inserted into the four middle cylinders respectively, a top plate is connected to the tops of the four inner cylinders through bolts, the bearing platform is arranged at the top of the top plate, a lower bottom plate is welded to the outer wall of the bottom of each lifting cylinder, and a hydraulic cylinder is connected tothe outer wall of the top of each lower bottom plate through bolts. According to the lifter, the hydraulic cylinders are used for driving the lifting cylinders to move in the supporting cylinders, sothat first connecting ropes and second connecting ropes drive the middle cylinders and the inner cylinders to ascend synchronously along with the lifting cylinders, the height of the bearing platformcan be quickly increased during starting, and consequently the transport efficiency of the lifter is improved; and moreover, the structure is simple, and the manufacturing cost of the lifter is saved.

    本发明涉及升降设备技术领域,具体是一种承载平台可移动的升降机,包括底板,底板的顶部外壁通过螺栓连接有四个支筒,四个支筒的内部均活动插接有升降筒,四个升降筒的内部均活动插接有中间筒,四个中间筒的内部均活动插接有内筒,四个内筒的顶部通过螺栓连接有顶板,顶板的顶部设置有承载台,升降筒的底部外壁焊接有下底板,下底板的顶部外壁通过螺栓连接有液压缸。本发明利用液压缸带动升降筒在支筒内部进行运动,使得第一连接绳和第二连接绳分别带动中间筒和内筒进行与升降筒同步上升,使得承载台的高度在启动时能够实现快速升高,因此提高了升降机的运输效率的效果,并且结构简单,节约了升降机的制造成本。
