Description

Technical Field

[0001] This utility model relates to the field of railway vehicle equipment technology, specifically an AGV vehicle with a traction center pin used for railway vehicle maintenance or manufacturing. Background Technology

[0002] Currently, in railway vehicle depots, some repair bays have maintenance trenches, causing the inner wheels of AGVs (Automated Guided Vehicles), which rely on the ground between the two rails for support, to lose support. Simultaneously, the lifting columns of the bogie-lifting machine are located outside the rails at the repair bays, causing interference between the lifting columns and the outer wheels of the AGVs. Therefore, the current mainstream practice in depots is to manually push the bogies off the ground rails from under the vehicle into the repair bay. The main disadvantages of this method are: high labor intensity, low efficiency, and inability to achieve automated operation.

[0003] Over the years, various depots across the railway have experimented with a variety of AGV vehicles with different traction interface forms, but all of them have been limited by the mindset of pushing and grabbing wheels or axles at the bottom of the bogie. Due to the large number of components around the wheels or axles of the wheelset, the space at the bottom of the bogie is greatly restricted. In addition, there are great differences in the structure between railway freight cars, passenger cars and EMUs, and each has different models and specifications, resulting in a variety of existing AGV vehicles with diverse structures and no universality.
