Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway freight car equipment technology, specifically an AGV vehicle with a lifting device for railway freight car maintenance or manufacturing. Background Technology
[0002] Currently, AGVs used for the maintenance or manufacturing of railway freight cars have difficulty crossing ground tracks within the production workshop. They require manual intervention by temporarily laying materials on the ground tracks to allow them to cross. After the AGVs have passed, these temporary materials must be manually removed before the freight 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 in use across the railway all lift the wheelsets from the bottom of the truck wheelsets. Because the space under the truck wheelsets is very small, the lifting device of the AGV is complex and expensive. Utility Model Content
