[0062] The present invention will be further described below in conjunction with the accompanying drawings.

[0063] During the bogie maintenance process, it is necessary to disassemble it from the car-mounting platform in the maintenance warehouse, separate it from the car body, and then transport it to a special bogie maintenance line. In the bogie maintenance line, the bogie undergoes a series of disassembly, inspection, measurement, maintenance, assembly and other maintenance processes. After the maintenance is completed, the bogie needs to be transported to the car-mounting platform in the maintenance warehouse and assembled with the car body. Existing bogies are usually transported by manual pushing and overhead crane lifting. During transportation, the bogie will be several meters above the ground, and the weight of the bogie is as high as several tons. The handling of the bogie depends on the reliability of the lifting tooling and the proficiency of the operator. It is not only labor-intensive and consumes manpower and material resources, but also has a high risk factor and poses a great safety risk.

[0064] Embodiment 1

[0065] like Figure 1-Figure 4As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a bogie handling structure, including a main beam 10, a running device 20, a lifting and supporting device 30 and a horizontal telescopic device 40; the running devices 20 are respectively arranged at both ends of the main beam 10, and the running device 20 is used to transport the bogie 50 so that the bogie 50 can move between various workstations; the lifting and supporting device 30 is arranged on the running device 20, and the lifting and supporting device 30 is used to drive the bogie 50 to move in the height direction; the horizontal telescopic device 40 is movably arranged on the lifting and supporting device 30, and the horizontal telescopic device 40 can move along the length direction to approach and support the bearing position 510 of the bogie 50.

[0066] As can be seen from the above, the bogie transport structure is driven to move by the running device 20, so that the bogie transport structure can move between various workstations to prepare for transporting the bogie 50; the horizontal telescopic device 40 is moved in the length direction to ensure that the horizontal telescopic device 40 is close to the bogie 50 in the length direction, and the horizontal telescopic device 40 lifts the bearing position 510; the horizontal telescopic device 40 is driven to move in the height direction by the lifting and lifting device 30, and the bogie 50 moves with the horizontal telescopic device 40. When the lifting and lifting device 30 drives the bogie 50 to move upward, the bogie 50 leaves the upper surface of the track, and the lifted bogie 50 is transported with the running device 20. Therefore, the bogie 50 can be transported back and forth between multiple workstations in the maintenance workshop through the bogie transport structure. The entire transportation process does not require manual pushing and overhead crane lifting, which saves time and effort, and solves the problem that the existing bogie 50 transportation has high labor intensity, consumes manpower and material resources, and has a high risk factor.

[0067] When transporting the bogie 50, the running device 20 moves to the bogie 50, and the two running devices 20 are respectively located on both sides of the bogie 50, and the main crossbeam 10 is located above the bogie 50. The lifting and supporting device 30 drives the horizontal telescopic device 40 to move downward, so that the horizontal telescopic device 40 moves to the bottom of the bogie 50, and the horizontal telescopic device 40 moves along the length direction until the horizontal telescopic device 40 is aligned with the bearing position 510 of the bogie 50, and then the lifting and supporting device 30 is used to drive the horizontal telescopic device 40 to move upward. The horizontal telescopic device 40 supports the bearing position 510 of the bogie 50 and drives the bogie 50 to leave the upper surface of the track, and then the running device 20 transports the bogie 50 to the next workstation.

[0068] Since the bottom space of the bogie 50 is narrow, it is difficult for the existing AGV to complete the transportation operation of the bogie 50. The present invention supports the bogie 50 on both sides by lifting the bearing position 510 of the bogie 50, without moving to the bottom space of the bogie 50 for operation.

[0069] It should be noted that the bogie 50 includes a wheelset, a side frame and a bolster. The wheelset is the part where the train contacts the rails. The wheelset includes wheels, axles and axle necks. The part of the axle protruding outside the wheel is called the axle neck, and the bearing position 510 is located on the axle neck.

[0070] It should also be noted that if Figure 1 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction.

When the lifting and lifting device 30 drives the bogie 50 to move upward, the bogie 50 leaves the upper surface of the track, and the lifted bogie 50 is transported with the running device 20. Therefore, the bogie 50 can be transported back and forth between multiple workstations in the maintenance workshop through the bogie transport structure. The entire transportation process does not require manual pushing and overhead crane lifting, which saves time and effort, and solves the problem that the existing bogie 50 transportation has high labor intensity, consumes manpower and material resources, and has a high risk factor.

[0074] When transporting the bogie 50, the running device 20 moves to the bogie 50, and the two running devices 20 are respectively located on both sides of the bogie 50, and the main crossbeam 10 is located above the bogie 50. The lifting and supporting device 30 drives the horizontal telescopic device 40 to move downward, so that the horizontal telescopic device 40 moves to the bottom of the bogie 50, and the horizontal telescopic device 40 moves along the length direction until the horizontal telescopic device 40 is aligned with the bearing position 510 of the bogie 50, and then the lifting and supporting device 30 is used to drive the horizontal telescopic device 40 to move upward. The horizontal telescopic device 40 supports the bearing position 510 of the bogie 50 and drives the bogie 50 to leave the upper surface of the track, and then the running device 20 transports the bogie 50 to the next workstation.

[0075] Since the bottom space of the bogie 50 is narrow, it is difficult for the existing AGV to complete the transportation operation of the bogie 50. The present invention supports the bogie 50 on both sides by lifting the bearing position 510 of the bogie 50, without moving to the bottom space of the bogie 50 for operation.

[0076] It should be noted that the bogie 50 includes a wheelset, a side frame and a bolster. The wheelset is the part where the train contacts the rails. The wheelset includes wheels, axles and axle necks. The part of the axle protruding outside the wheel is called the axle neck, and the bearing position 510 is located on the axle neck.

[0077] It should also be noted that if Figure 1 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction.

In addition, when the steering wheel 2203 crosses the track and rolls onto the track groove, the shock absorbing assembly 2201 plays a role of shock absorption.

[0082] like Figure 5 As shown, it should be noted that the steering assembly 2204 includes a first steering gear 2213, a second steering gear 2214 and a steering motor 2215; the first steering gear 2213 is mounted on the bottom of the second guide cylinder 2207, and the travel seat 2202 is rotatably mounted on the inner wall of the first steering gear 2213 through a rolling bearing; the steering motor 2215 is mounted on the travel seat 2202, and the second steering gear 2214 is mounted on the rotating shaft of the steering motor 2215, and the second steering gear 2214 is meshed with the first steering gear 2213.
