Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway vehicle equipment technology, specifically an AGV vehicle that can both cross tracks and traction wheelsets. Background Technology
[0002] Currently, AGVs used in railway vehicle maintenance or manufacturing have difficulty crossing ground tracks within production workshops. They require manual intervention by temporarily laying materials on the tracks for a transition before they can cross. After the AGVs have passed, these temporary materials must be manually removed; otherwise, the wheelsets cannot pass. The main drawback is that the difficulty in crossing tracks prevents automated and unmanned operations. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide an AGV vehicle that can both cross tracks and traction wheelsets, so as to solve the problems mentioned in the background art.

The wheelsets 2 running on the rails 3 include wheel axles 2B. The rails 3 include rails 3B and wheel flange grooves 3C. The AGV vehicles 4 include a T-shaped body 4A, a front wheel assembly 4B, a rear wheel assembly 4C, and a lifting device 4D. Both the front wheel assembly 4B and the rear wheel assembly 4C include running wheels 4E. The T-shaped body 4A includes a short front section 4A1 and a long rear section 4A2. The front wheel assembly 4B is mounted on the short front section 4A1. The rear wheel assembly 4C mounted on the long rear section 4A2 includes an inner wheel 4C1 and an outer wheel 4C2. The inner wheel 4C1 is located inside the wheel flange groove 3C, and the outer wheel 4C2 is located outside the rail 3B.
[0005] The AGV vehicle 4 can cross the track 3 via the inner wheel 4C1 and the outer wheel 4C2; the lifting device 4D is installed on the short front part 4A1, which is drilled into the bottom of the wheelset 2 on the ground. After the lifting device 4D is lifted, it locks the axle 2B. At this time, the AGV vehicle 4 can pull the wheelset 2 to run on the rail 3B.
[0006] As a further aspect of this utility model: the lifting device 4D includes a lifting fork 4D1. When the lifting device 4D retracts, the highest position of the original position of the lifting fork 4D1 is lower than the lowest position of the axle 2B; when the lifting device 4D extends, the lifting fork 4D1 can lock the axle 2B.
[0007] As a further embodiment of this utility model: when the AGV vehicle 4 crosses the track 3, the length direction of the wheelset 2 on the AGV vehicle 4 is perpendicular to the length direction of the track 3.
[0008] As a further embodiment of this utility model: the center distance between the two inner wheels 4C1 is equal to the center distance between the two traveling wheels 4E in the front wheel device 4B.
[0009] As a further embodiment of this utility model: the traveling wheel 4E includes a steering wheel 4E1.
[0010] In summary, compared with existing technologies, this invention achieves automatic AGV crossing of ground tracks by placing the inner and outer wheels on the inner and outer sides of the track, respectively. Its main advantage is that the AGV can automatically and smoothly cross the track. Attached Figure Description
