Description

Technical Field

[0001] This utility model relates to the field of railway freight car equipment technology, specifically an AGV vehicle that can cross track devices 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. 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 cross track devices for the maintenance or manufacture of railway freight cars, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The workshop 1 of a railway freight car depot or rolling stock factory includes freight car wheelsets 2, track devices 3, and AGV vehicles 4 that can run on the ground. The freight car wheelsets 2 include wheel flanges 2A and axles 2B. The freight car wheelsets 2 run on the track devices 3. The track devices 3 include track grooves 3A that are lower than the ground. The AGV vehicles 4 include a T-shaped body 4A, a front wheel device 4B, a rear wheel device 4C, and a lifting device 4D.

The lifting device 4D is installed on the short front part 4A1. When the lifting device 4D is lifted, it can lift the axle 2B, making the wheel flange 2A higher than the ground and the track device 3; when the lifting device 4D is retracted, its top surface is lower than the lowest position of the axle 2B, and the short front part 4A1 of the AGV vehicle 4 can penetrate into the bottom of the truck wheelset 2 on the ground. The front wheel assembly 4B is mounted on the short front part 4A1, and the rear wheel assembly 4C, mounted on the long rear part 4A2, includes an inner wheel 4C1 and an outer wheel 4C2, which are located on the inner and outer sides of the track groove 3A, respectively. Through the inner wheel 4C1 and the outer wheel 4C2, the AGV vehicle 4 can carry the freight car wheelset 2 across the track device 3 to realize the transportation of the freight car wheelset 2 within the factory building 1.

[0005] As a further aspect of this utility model: the lifting device 4D includes a movable fork 4D1. When the lifting device 4D retracts, the highest position of the movable fork 4D1 is lower than the lowest position of the axle 2B. When the lifting device 4D extends and the movable fork 4D1 moves, the movable fork 4D1 always holds the axle 2B in place to prevent the axle 2B from rolling out of the lifting device 4D.

[0006] As a further aspect of this utility model: when the AGV vehicle 4 crosses the track device 3, the length direction of the freight car wheelset 2 it carries is perpendicular to the track device 3, and the tilt of the freight car wheelset 2 is within the vertical plane of the center line of the axle 2B, which will not cause the freight car wheelset 2 to roll off.

[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. When the front wheel device 4B crosses the top protrusion 3B1, the tilt of the truck wheelset 2 is within the vertical plane of the center line of the axle 2B.

[0009] As a further embodiment of this utility model: the ground inside the factory building 1 includes a V-shaped block 1A, and the AGV vehicle 4 can place the truck wheelset 2 it carries on the V-shaped block 1A, or remove the truck wheelset 2 from the V-shaped block 1A.

[0011] As a further embodiment of this utility model: the traveling wheel 4E includes a steering wheel 4E1.

[0012] As a further embodiment of this utility model: the front wheel device 4B includes a three-wheel device 4B3.

[0013] As a further embodiment of this utility model: the lifting device 4D includes a sliding seat lifting device 5, which includes a sliding seat 5A, a sliding seat lifting device 5B, and a V-shaped fork 5C. The sliding seat lifting device 5B is located between the axle 2B and the high and long rear part 4A2, and the V-shaped fork 5C is located at the bottom of the sliding seat 5A. When the sliding seat lifting device 5B is lifted, the V-shaped fork 5C can lift the axle 2B, so that the wheel flange 2A is higher than the top surface boss 3B1.

[0014] 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 groove, respectively. Its main advantages are: improved operational efficiency and fully automated, unmanned operation. Attached Figure Description
