Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway passenger vehicle equipment technology, specifically an AGV vehicle with a lifting device for railway passenger vehicle maintenance or manufacturing. Background Technology
[0002] Currently, AGVs used for the maintenance or manufacturing of railway passenger cars have difficulty crossing ground tracks within the production workshop. They require manual intervention by temporarily laying materials on the ground tracks for a transition before they can cross. After the AGVs have passed, these temporary materials must be manually removed before the passenger car wheelsets can pass. The main drawbacks are low operational efficiency and the inability to achieve automated or unmanned operation.
[0003] Moreover, the AGVs currently used across the railway system lift the passenger wheelsets from the bottom. Due to the presence of brake discs, the width of the lifting device must be less than the axial distance between the two brake discs, causing the passenger wheelsets to be extremely unstable during transportation and posing a safety risk.
