Description

Technical Field

[0001] This utility model relates to the field of railway vehicle equipment technology, specifically an AGV vehicle that can both ride on rails and haul wheelsets. Background Technology

[0002] Currently, in the wheel and axle workshops of railway vehicle depots, some maintenance equipment is located on the inner and outer sides of two steel rails on the ground. Equipment on the inner side causes the AGV's ground wheels to lose support, while equipment on the outer side interferes with the AGV's position. Therefore, the current mainstream practice for wheelset transportation is to manually or using wheel pullers (which pose safety hazards) to propel the wheelsets along the rails. Its main drawbacks are high labor intensity and the inability to automate the 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 ride on rails and haul wheelsets, so as to solve the problems mentioned in the background art.

Through the track wheel 4A, the AGV vehicle can ride on the rail 3B. When the traction hook 4C hooks the axle 2B, the AGV vehicle 4 can pull the wheelset 2 to run on the rail 3B.

[0005] As a further embodiment of this utility model: the AGV vehicle 4 includes a lifting device 4D; the lifting device 4D can change the relative height between the ground wheel 4B and the track wheel 4A.

[0006] As a further embodiment of this utility model: the AGV vehicle 4, through the lifting device 4D, can make the ground wheel 4B detach from the ground and the track wheel 4A 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 the track wheel 4A run on the ground; it can also make the track wheel 4A higher than the rail 3B and the ground wheel 4B run on the ground.

[0007] As a further embodiment of this utility model: the ground wheel 4B includes an inner wheel 4B1 located inside the wheel flange groove 3C.

[0008] As a further embodiment of this utility model: the AGV vehicle 4 includes a vehicle body 4E, a track wheel 4A, a traction hook 4C and a lifting device 4D, all of which are mounted on the vehicle body 4E, and an inner wheel 4B1 is mounted on the lifting device 4D.

[0009] As a further embodiment of this utility model: the traction hook 4C includes a rotating rod device 7, which includes a rotating seat 7A, a rotating rod 7B, and a V-shaped fork 7C. The rotating seat 7A is mounted on the vehicle body 4E, and the V-shaped fork 7C is located at the front end of the rotating rod 7B. The rotating rod 7B rotates on the rotating seat 7A. When the AGV vehicle 4 does not traction the wheel pair 2, the rotating rod 7B is in a vertical state.

[0010] In summary, compared with the prior art, this utility model avoids positional interference between the AGV vehicle and ground maintenance equipment by having the track wheels ride on the rails; its main advantages are: the AGV vehicle has a simple structure and a high degree of production automation.
