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 ride on tracks. 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, jacking machines are located outside the rails at the repair bays, potentially causing the lifting columns of these machines to interfere with the outer wheels of the AGVs. Therefore, the current mainstream practice in depots is to manually push the bogies off the ground from the rails into the repair bays from beneath the vehicles. The main drawbacks of this method are high labor intensity, low efficiency, and inability to achieve automated 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 both cross tracks and ride on tracks, 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 vehicle depot or vehicle factory includes a vehicle 1B, a track 3 and an AGV vehicle 4. The track 3 is longitudinal in length. The vehicle 1B includes a bogie 1B1, the bogie 1B1 includes a wheelset 2, the wheelset 2 includes a wheel flange 2A and an axle 2B, the track 3 includes a rail 3B and a wheel flange groove 3C, and the wheelset 2 runs on the rail 3B. The AGV 4 includes track wheels 4A, ground wheels 4B, and a hook device 4C. By running on the ground with track wheels 4A and ground wheels 4B, the AGV 4 can cross the wheel flange groove 3C and the rail 3B laterally. By riding on the rail 3B with track wheels 4A, the AGV 4 can longitudinally drive the hook device 4C into the bottom of the bogie 1B1. After the hook device 4C hooks the bogie 1B1, the AGV 4 can pull the bogie 1B1 to run on the rail 3B.

[0005] As a further aspect of this invention: the AGV vehicle 4 includes a lifting device 4D, which can change the relative height between the ground wheels 4B and the track wheels 4A. As a further embodiment of this utility model: the lifting device 4D can lift the ground wheel 4B off the ground and allow the track wheel 4A to ride on the rail 3B; it can also make the ground wheel 4B and the track wheel 4A at the same height, and both of them run on the ground; it can also make the ground wheel 4B higher than the rail 3B and allow the track wheel 4A to run on the ground; and it can also make the track wheel 4A higher than the rail 3B and allow the ground wheel 4B to run on the ground.

[0006] As a further embodiment of this utility model: the ground wheel 4B includes an inner wheel 4B1 located inside the wheel flange groove 3C.

[0007] As a further embodiment of this utility model: the AGV vehicle 4 includes a vehicle body 4E, a track wheel 4A, a hook device 4C and a lifting device 4D are all mounted on the vehicle body 4E, and the inner wheel 4B1 is mounted on the lifting device 4D.

[0008] As a further embodiment of this utility model: the hook device 4C includes a rotating rod device 5, which includes a rotating rod 5A, a hook wheel 5B, and a rotation drive 5C. The hook wheel 5B installed at the front end of the rotating rod 5A does not interfere with the bogie 1B1 in its original state. After the hook wheel 5B hooks the wheel flange 2A through the rotation drive 5C, the AGV vehicle 4 pulls the bogie 1B1 forward.

[0009] As a further embodiment of this utility model: the hook device 4C includes a rotating fork device 6, which includes a V-shaped fork 6A and a rotating shaft 6B. The V-shaped fork 6A, which is installed at the front end of the rotating shaft 6B, includes a roller 6A1. When the V-shaped fork 6A is in a horizontal position, it does not interfere with the bogie 1B1. When the V-shaped fork 6A is in a vertical position, the V-shaped fork 6A can hold the axle 2B, so that the roller 6A1 pushes or hooks the axle 2B forward.

[0010] As a further embodiment of this utility model: the car body 4E includes a pusher 4E1, which pushes the bogie 1B1 to run on the rail 3B. At this time, the hook wheel 5B or the roller 6A1 can prevent the bogie 1B1 from rushing forward.

[0011] As a further embodiment of this utility model: the track wheel 4A includes a steering wheel 4A1, and the inner wheel 4B1 includes a Mecanum wheel 4B1A.

[0012] In summary, compared with existing technologies, this invention enables the AGV to traverse rails laterally by using track wheels and ground wheels to move on the ground; then, by riding on the rails, the AGV's hook device engages with the bottom of the bogie. Once the AGV's hook device engages with the bogie, it can automatically pull the bogie to run on the rails. Its main advantages are: improved work efficiency and the realization of fully automated, unmanned operation. Attached Figure Description
