Track positioning and docking mechanism and track positioning and docking method during layer changing of shuttle vehicle

Abstract

The invention discloses a track positioning and docking mechanism and a track positioning and docking method during layer change of a shuttle vehicle. The problems of how to realize smooth and accurate docking of two track flat layers at low cost and how to prevent tracks at the docking position from deforming are solved. According to the track positioning and docking mechanism, positioning seats are arranged on a steel structure frame of a four-stand-column layer-changing elevator, swing arm assemblies are arranged on the two sides of a lifting platform of the four-stand-column layer-changing elevator, a driving motor synchronously drives four swing arms on the two sides of the lifting platform of the layer-changing elevator through a transmission device, the four swing arms and the four positioning seats on the steel structure frame are positioned in a lap joint mode, accurate positioning of the whole lifting platform during layer changing on the steel structure frame is achieved, so that accurate butt joint of a shuttle mother vehicle track on the lifting platform and a shuttle mother vehicle walking track on the outer side of a goods shelf is indirectly guaranteed, the swing arms synchronously drive a safety limiting swing arm to swing, and limiting and receding of walking of a shuttle mother vehicle are achieved; and the defect that a butt joint rail is prone to deformation due to butt joint adjusting stress is thoroughly overcome, and the stress of the two ends of the platform is even.

Description

technical field [0001] The invention relates to a multi-layer intensive storage system using a shuttle car to store and retrieve goods, in particular to a shuttle mother car track arranged on the lifting platform of a four-column layer-changing hoist in the dense storage system, and a shuttle bus on one side of the shelf. The mother car changes layers and walks the track in the three-dimensional passage, and realizes a track positioning docking mechanism and a positioning docking method for stable and accurate docking. Background technique [0002] The shelves of the dense storage system generally have more than a dozen or even dozens of floors, and the entire shelf is arranged continuously in a matrix on the plane. This kind of shelf usually uses automatic material handling equipment (that is, the sub-shuttle mother car) to carry out goods in and out of the warehouse; The outer side of the shelves is arranged continuously in a matrix. There are three-dimensional passages fo...
