Description

Technical Field

[0001] This utility model relates to the field of railway vehicle equipment technology, specifically a railway track interface that allows AGV vehicles to pass laterally and wheelsets to pass longitudinally. Background Technology

[0002] Currently, in railway vehicle depot production workshops, existing AGVs require rubber pads to be placed in the wheel flange grooves beforehand when they pass laterally through the ground rails. These pads must be removed when the wheelset passes longitudinally through the intersection with the ground rails. Due to the presence of protrusions on the top surface of the ground rails, the outer rubber coating of the AGV's wheels is easily bumped and damaged. Its main disadvantages are: the AGV cannot automatically cross rails, and the wheels have a relatively short lifespan. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a railway track interface that allows AGV vehicles to pass laterally and wheelsets to pass longitudinally, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A production workshop in a railway vehicle depot or vehicle factory includes wheelsets 2, rails 3, and AGV vehicles 4. The length direction of the rails 3 is longitudinal. The wheelsets 2 run on rails 3A. The wheelsets 2 include wheel flanges 2A. The rails 3 include rails 3A and wheel flange grooves 3B that are lower than the ground. Rails 3A include top surface bosses 3A3 that are higher than the ground. AGV vehicles 4 include traveling wheels 4A. The traveling wheels 4A include inner wheels 4A1 and outer wheels 4A2. The inner wheels 4A1 are located inside the wheel flange grooves 3B, and the outer wheels 4A2 are located outside the rails 3A. Rails 3A include notches 3A1 and wheel flange support rails 3A2. The notches 3A1, whose upper plane is at the same height as the ground, are located at the intersection of the traveling wheels 4A and the rails 3A. The effective length of the wheel flange support rails 3A2 is greater than or equal to the length of the notches 3A1. The top surface of the wheel flange support rails 3A2 is at the same height as the bottom of the wheel flanges 2A.

[0005] At the gap 3A1, the AGV 4 can pass through the inner wheel 4A1 and the outer wheel 4A2, and smoothly cross the flange groove 3B. The wheelset 2 can pass through the gap 3A1 smoothly in the longitudinal direction by running on the flange rail 3A2 via the flange 2A.

[0006] As a further embodiment of this utility model: the flange support rail 3A2 is located inside the flange groove 3B.

[0007] As a further embodiment of this utility model: the wheel flange rail 3A2 includes rail slopes 3A2A at both ends.

[0008] As a further embodiment of this utility model: the notch 3A1 includes chamfered notches 3A1A located on both sides of the longitudinal direction.

[0009] In summary, compared with the prior art, the features of this utility model are: 1) It uses inner and outer wheels, so there is no need to place rubber pads in the wheel flange groove, allowing the AGV to cross over the groove; 2) A notch with the top surface at the same height as the ground is designed at the intersection of the ground rails, so the outer rubber coating of the traveling wheels will not be bumped or damaged; 3) A wheel flange support rail is added at the notch, so it will not affect the wheelset's smooth passage through the notch of the ground rails. In summary, the main advantages of this utility model are: the AGV can automatically cross the rails, achieving unmanned operation; the traveling wheels have a longer service life; and the rail interface structure is simple.
