The invention provides an automatic vertical descending telescopic device which comprises a main frame and two rotating shafts symmetrically arranged on the front side and the rear side of the main frame, the two ends of each rotating shaft are each fixedly provided with a steel belt wheel, a steel belt is wound around each steel belt wheel, one end of each steel belt is fixed to the corresponding steel belt wheel, and the other end of each steel belt is fixed to the corresponding steel belt wheel. The other ends of the two connecting rods are connected with one corner of the grabbing device, and the grabbing device is used for grabbing the carrying box; the two rotating shafts synchronously and reversely rotate through a driving mechanism arranged on the main frame to drive the four steel belts to synchronously stretch out and draw back in the vertical direction. And the four steel belts are all conductive steel belts, so that electricity and signals can be transmitted to the grabbing device. Lifting of the carrying box is achieved through vertical descending and stretching of the four steel belts, the carrying box can carry stably in the lifting process, falling of objects can be avoided, safety is improved, and the objects are convenient to load and unload.

    本发明提供一种自动垂降伸缩装置,包括主框架、对称设置在主框架前后侧的两个转轴,每个所述转轴的两端均固定有一个钢带轮,每个所述钢带轮上卷绕有钢带,四个所述钢带一端分别固定在一个钢带轮上,另一端分别与抓取装置的一个角部连接,所述抓取装置用于抓取运载箱;两个所述转轴通过设于主框架上的驱动机构同步反向旋转,带动四个所述钢带沿竖直方向同步伸缩;且四个钢带均为导电钢带,能将电和信号传输到抓取装置。本发明通过四个钢带垂降伸缩实现运载箱的吊装,可让运载箱在吊装过程中运载平稳,能避免物品掉落,提高安全性,且便于装卸物品。
