Multilayer shuttle bus layer change safety device

Abstract

The invention discloses a multilayer shuttle bus layer change safety device. The device comprises a shelf side limiting module, a lifter side limiting module and a swing arm device. The shelf side limiting module is mounted on the outer side of the end of a walking rail of each layer of shuttle buses; and the lifter side limiting module and the swing arm device are mounted on a layer change lifterlifting table for lifting with the lifting table. The two limiting modules have no opening and closing power, and are driven by the swing arm device. The two side limiting modules are provided with guide grooves; and when the shuttle buses are transited between two side rails, the swing arm device and the guide grooves of the limiting modules are coacted to form the two side rails as a temporaryrigid connecting structure. The device is compact in structure, realizes automatic opening and closing of the limiting modules through a low-cost mode, achieves a correcting effect on general stop andstaggering problems of the layer change lifter lifting table, and eliminates the sinking and rebound phenomenon caused by change, corresponding to the load change, of the flexibility of the ends of the rails in the transition process of the shuttle buses.

Description

technical field [0001] The invention belongs to the technical field of automated management of dense three-dimensional warehouses, and in particular relates to a safety device for changing layers of a multi-layer shuttle vehicle. Background technique [0002] With the vigorous development of the e-commerce industry and the continuous improvement of logistics technology, the multi-storey shuttle vehicle intensive storage system is more and more widely used in China. Since the number of shuttle vehicles can be optimally configured according to demand, the multi-layer operation mode is often more economical and applicable than the single-layer operation mode. However, the use of multi-layer operation mode will inevitably face the problem of smooth layer change of shuttle vehicles. The shuttle car layer change is generally realized by a hoist. In the existing technology, the shortcomings are mainly reflected in the following three aspects: ①The limit device at the end of the ru...
