Description

Auxiliary overhaul equipment for rapidly overhauling RGV trolley

Technical Field

The utility model relates to the field of logistics, in particular to auxiliary overhaul equipment for rapidly overhauling an RGV trolley.

Background

Under normal conditions, the RGV trolley normally operates on the circular track, and when the RGV needs to be overhauled and maintained, the RGV is usually achieved in an on-site overhauling mode on the running track, so that the complex operation of hoisting is reduced. However, if the maintenance is performed on the original rail, other normal RGV trolleys on the whole line are inevitably caused to stop running, so that the running efficiency of the other normal RGV trolleys is seriously affected. In addition, because the RGV trolley is relatively complex in structure, the maintenance work of the RGV trolley is difficult to complete in a short time, and therefore the efficiency of a traditional maintenance mode is lower.

Currently, some improved schemes are also proposed for overhauling an RGV trolley, for example, chinese patent grant publication No. CN218318991U discloses an overhauling device for annular RGV overhauling, which realizes the final overhauling process by arranging structures such as an overhauling transfer trolley, a transfer guide rail, an overhauling guide rail and the like on one side of an annular guide rail and sequentially transferring the RGV trolley on the guide rail. However, this transfer structure requires the provision of guide rails of different directions, resulting in a complicated structure and lack of flexibility in use. In addition, due to the fact that guide rails in different directions are required to be arranged, the height of the transfer structure in the vertical direction is high, the guide rails are difficult to match with the lower guide rails of the RGV trolley, special guide rails are required, and the use flexibility of the transfer structure is severely limited.
