It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0029] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0030] The present utility model provides a rail transit wheel pair rotating wheel 220 device, including: a support mechanism 100, a transmission module 200 and a jacking module 300; the support mechanism 100 is used to support the wheel pair; the transmission module 200 is installed on one side of the support mechanism 100 and is used to rotate the wheel pair; the jacking module 300 is installed below the support mechanism 100 and is used to limit the position of the wheel pair and push the wheel pair.

[0031] Support the wheel set through the support mechanism 100, and the drive module 200 rotates the wheel set, enabling cleaning or other operations on the wheel set. Limit the position of the wheel set and push the wheel set through the lifting module 300, limit it during the rotation of the wheel set, and after completion, the wheel set can be pushed out of the working area. Ensure the efficiency and quality of the cleaning of the rail vehicle wheel set, liberate the labor force, reduce the project cost, and improve the adaptability to different wheel sets.

[0032] In one embodiment, a process track 110 is provided above the support mechanism 100, and the wheel set can move along the process track 110.

[0033] Exemplarily, the process track 110 can be connected to the wheel track, enabling the wheel set to reach the corresponding position along the track.

[0034] In one embodiment, the drive module 200 includes: a motor 210, a runner 220, a gearbox 230, and a transmission shaft 240; the gearbox 230 is installed on one side of the support mechanism 100, the runner 220 is installed on the other side of the support mechanism 100, and the gearbox 230 is connected to the runner 220 through the transmission shaft 240; the motor 210 is installed on one side of the gearbox 230 and is used to drive the transmission mechanism inside the gearbox 230 to rotate.

[0035] Multiple runners 220 can be provided. The runners 220 are arranged side by side along the radial direction of the track and are connected to the gearbox 230 through the transmission shaft 240. The motor 210 can drive the gears in the gearbox 230 to rotate. Through gear meshing, the rotational speed of the output shaft of the motor 210 is reduced and finally output by the transmission shaft 240. The transmission shaft 240 drives the runner 220 to rotate, and the runner 220 drives the wheel set to rotate.

[0036] In one embodiment, the drive module 200 can be lifted and lowered along the vertical direction of the support mechanism 100.

[0037] Before the wheel set enters the runner 220 device, the drive module 200 lowers its elevation under the action of an external lifting mechanism, so that the upper contact surface of the runner 220 is below the rail surface, preventing the wheel set from impacting the runner 220 when entering and causing damage.

[0038] In one embodiment, the lifting module 300 includes two positioning cylinders 310, and the bottom ends of the positioning cylinders 310 are fixed to the ground. The upper surface of the positioning cylinder 310 is connected to the bottom of the process track 110. Through holes are provided on both sides of the process track 110 where the positioning cylinders 310 are installed, and the through holes are aligned with the pistons of the positioning cylinders 310.

[0039] When the wheel set enters the runner 220 station, the positioning cylinder 310 near the wheel output side of the lifting module 300 extends the ejector rod to block the wheel from continuing to roll, restricting the wheel set on the process track 110.

[0040] In one embodiment, the jacking module 300 further includes a plurality of push wheel cylinders 320, which are fixedly installed at the bottom of the process track 110. The process track 110 is provided with a channel that is aligned with the piston of the push wheel cylinder 320.

[0041] After the work is completed, the ejector rod of the push wheel cylinder 320 extends to push the wheel set to move away from the process track 110.

[0042] The specific usage method is as follows: Before the wheel set enters the rotating wheel 220 device, the transmission module 200 lowers its elevation under the action of an external lifting mechanism, so that the upper contact surface of the rotating wheel 220 is below the rail surface to prevent the wheel set from impacting the rotating wheel 220 when entering and causing damage. When the wheel set enters the rotating wheel 220 station, at the same time, the positioning cylinder 310 near the wheel outlet side of the jacking module 300 extends its ejector rod to block the wheel from continuing to roll and restricts the wheel set on the process track 110. Before the wheel set cleaning work, the external lifting mechanism drives the transmission module 200 to gradually rise until the elevation of the rotating wheel 220 exceeds the elevation of the process track 110 of the jacking module 300, so that the wheel flange of the wheel set falls on the rotating wheel 220, and then the rising stops. When the rotating wheel 220 starts, the motor 210 starts to work. Since the motor 210 has a high speed, its output shaft meshes with the transmission mechanism in the gearbox 230. After the speed is reduced, it is output to the rotating wheel 220 by the transmission shaft 240, and the rotating wheel 220 drives the wheel set to rotate, thus achieving the effect of the rotating wheel 220. After the work is completed, the transmission module 200 lowers its elevation under the action of the external lifting mechanism, and the ejector rod of the push wheel cylinder 320 extends to push the wheel set to move away from the process track 110.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
