In order to solve the technical problem that the lifting height of an existing screw lifting device is limited, the invention provides a hollow screw tube and internal rotation screw combined device capable of being in segmented butt joint, which comprises a hollow screw tube, an internal rotation screw, a lifting bracket, a transmission mechanism and a driving device, the hollow solenoid is provided with a notch through which the lifting bracket and the transmission mechanism can pass; the internal rotation screw rod is arranged in the hollow screw tube and is in threaded connection with the hollow screw tube; the driving device drives the internal rotation screw rod to enable the internal rotation screw rod to rotate and ascend and descend along the hollow solenoid, and then the lifting support is driven to synchronously ascend and descend along a notch of the hollow solenoid and an external lifting carrier connected with the lifting support. The ports of the hollow screw tubes are provided with mutual butt joint mechanisms, and the mutual butt joint mechanisms can enable the thread screwing directions and the notches of the two hollow screw tubes to be communicated with each other, so that the internal screwing screw rod drives the lifting bracket to freely move from one hollow screw tube to the other hollow screw tube; by means of butt joint, the hollow solenoid can be extended without limitation, and free lifting without height limitation of an external lifting carrier is achieved.
本发明针对现有螺杆升降装置存在的升降高度受限之技术问题,提出了一种可分段对接的中空螺管与内旋螺杆组合装置,包括:中空螺管、内旋螺杆、升降支架、传动机构和驱动装置;中空螺管上开有可使升降支架和传动机构穿越的槽口;内旋螺杆装设在中空螺管内且两者螺纹旋合;驱动装置对内旋螺杆驱动可使其沿中空螺管旋转升降,进而带动升降支架沿中空螺管槽口以及与升降支架连接的外部升降载体同步升降。中空螺管端口设有相互对接机构,其可使两个中空螺管的螺纹旋向及槽口相互连通,使内旋螺杆带动升降支架可从一个中空螺管自由位移至另一中空螺管;以此对接可使中空螺管无限制地延长,使外部升降载体实现无高度限制的自由升降。
