Description

Technical Field

[0001] The utility model relates to the technical field of RGV power vehicle equipment, in particular to a mother-and-child RGV power vehicle. Background Art

[0002] RGV power vehicles are generally used to run on rails to transport other equipment or workpieces. Depending on the actual situation, the rails will be arranged vertically. The RGV power vehicle is equipped with two sets of mutually perpendicular rail wheels. The rail wheels can be lifted and lowered to offset the other set of rails to achieve vertical translation of the RGV power vehicle. During the movement, the RGV power vehicle needs to be separated from the original track as a whole, and then moved along the vertical track. This increases the energy loss during the movement of the RGV power vehicle. If part of the structure of the RGV power vehicle is run along the vertical track and the items are carried to the vertical track, and then the main body is kept in the original track position unchanged, it will greatly reduce the power consumption of the RGV power vehicle and achieve energy saving. People have conducted a lot of research on this. Utility Model Content
