The novel rapid screw elevator comprises a supporting frame, a guide rail, a screw, a first-stage lifting mechanism and a second-stage lifting mechanism, the guide rail is vertically arranged on the supporting frame, the screw is parallel to the guide rail, and the two ends of the screw are connected with the top end and the bottom end of the supporting frame correspondingly; the first-stage lifting mechanism comprises a threaded sleeve movably arranged on the screw in a sleeving mode and a driving assembly connected with the threaded sleeve, and the second-stage lifting mechanism comprises a threaded nut movably arranged on the threaded sleeve and a lifting platform movably arranged on the guide rail and connected with the threaded nut. The driving assembly is used for driving the threaded sleeve to ascend and descend in the axial direction of the screw and enabling the lifting platform to ascend and descend in the axial direction of the threaded sleeve. When the threaded sleeve of the driving assembly ascends and descends in the axial direction of the screw, the lifting platform does linear motion in the threaded sleeve in the same direction of moving towards the threaded sleeve, speed superposition is achieved, the lifting speed is higher, and the speed can be increased by more than one time compared with that of an existing screw type elevator.

    本发明公开了一种新型的快速螺杆式升降机,包括支撑框架、导轨、螺杆、一级升降机构以及二级升降机构,所述导轨垂直设置在支撑框架上,螺杆平行于所述导轨,其两端分别与支撑框架顶端以及底端连接,一级升降机构包括移动套设在螺杆上的螺纹套筒以及与螺纹套筒连接的驱动组件,二级升降机构包括移动设置在螺纹套筒上的螺纹螺帽以及移动设置在导轨上并与螺纹螺帽连接的升降平台,驱动组件用于驱动螺纹套筒沿螺杆轴向升降的同时使升降平台沿螺纹套筒轴向升降。本发明通过驱动组件螺纹套筒沿螺杆轴向升降的同时,升降平台朝螺纹套筒移动的相同方向在螺纹套筒做线性运动,实现速度叠加,升降速度更快,可比现行螺杆式电梯的速度提升一倍以上。
