Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation equipment and relates to a metallurgical vehicle operation system with steering capability. Background Art

[0002] Traditional metallurgical vehicles can only run on straight tracks. If the running direction needs to be changed, a turntable with a section of track on the disc needs to be set at the turning point, and the metallurgical vehicle needs to be rotated on the turntable at a certain angle to dock with the track in the other direction, and then the metallurgical vehicle needs to drive to the track at another angle. This design is difficult for plant design and construction, and the precision requirements for the docking of the turntable in the later stage are high, and the efficiency of metallurgical vehicle operation is low. As users' requirements for the efficiency of metallurgical vehicles increase, process design hopes to design the track as a continuous track with a curved section. However, in order to ensure safe operation, the original metallurgical vehicle has rims on both sides of the wheel, which can limit the wheel from running on the top surface of the track, and the distance between the rim and both sides of the track is usually only more than ten millimeters. When the front track is a curved section, there is a certain angle between the center of the track and the center of the wheel, and the original wheel does not have the ability to swing, which will cause the wheel to get stuck on the track and unable to run. Utility Model Content

[0003] In view of this, the purpose of the utility model is to solve the steering problem of metallurgical vehicles on curved track sections and to provide a metallurgical vehicle operating system with steering capability.

[0004] In order to achieve the above object, the utility model provides the following technical solutions:

[0005] A metallurgical vehicle operation system with steering capability comprises a driving wheel and a driven wheel arranged on both sides of a vehicle body, the driving wheel and the driven wheel are respectively arranged on a track, the driven wheel comprises a driven wheel, a driven wheel shaft, and a spherical bearing; the driven wheel shaft is rotatably arranged under the vehicle body through a bearing, and the driven wheel is rotatably sleeved on the driven wheel shaft through a spherical bearing; when the track is bent, the driven wheel rotates relative to the driven wheel shaft through the spherical bearing, thereby achieving steering.

[0006] Furthermore, the driving wheel includes a driving device, a driving wheel shaft, and a driving wheel; the driving wheel shaft is rotatably arranged under the vehicle body through a bearing, and the driving wheel is mounted on the driving wheel shaft and circumferentially clamped by a flat key; the driving device is connected to the driving wheel shaft to drive the driving wheel to rotate.

[0007] Furthermore, the driven wheel is provided with rims on both sides, the track is located between the rims on both sides of the driven wheel and is limited by the rims; the driving wheel has no rims on both sides.

[0008] Furthermore, a shaft sleeve is mounted on the driven wheel shaft, and the spherical bearing is axially limited by the shaft sleeve.

[0009] The beneficial effects of the utility model are:

[0010] 1. The utility model designs the wheel on one side of the track to be able to swing with the track bending angle. The friction between the wheel rim and the side of the track causes the wheel to rotate a certain angle on the spherical surface of the joint bearing, thereby keeping the rolling direction of the wheel consistent with the bending direction of the track to achieve steering.

[0011] 2. In the utility model, the driven wheel adopts a flange type, combined with a spherical bearing, to play a guiding role, while the driving wheel adopts a flangeless type to directly provide driving force. The driving wheel does not interfere with the side of the track, thereby avoiding steering jamming.
