[0051] like Figures 1-8 As shown, an embodiment of the present invention provides a wheelset displacement device, which includes a carrier frame 1, an in-situ drive assembly 2, a stop assembly 3 and a pushing assembly 4. The carrier frame 1 is rotatably provided with two limiting wheels 11. The in-situ drive assembly 2 includes an in-situ driver 21 and two driving wheels 22. The in-situ driver 21 can drive the two driving wheels 22 to rotate. The two driving wheels 22 are opposite to the two limiting wheels 11 one by one to form an in-situ supporting wheel group. The locomotive wheel set 100 can be placed on the in-situ supporting wheel group. The stop assembly 3 includes a stop driver 31 and a stop frame 32. The stop driver 31 can drive the stop frame 32 to stop the locomotive wheel set 100 from the output side of the in-situ supporting wheel group. The pushing assembly 4 includes a pushing driver 41 and a pushing frame 42. The pushing driver 41 can drive the pushing frame 42 to push the locomotive wheel set 100 on the in-situ supporting wheel group, and push the locomotive wheel set 100 out from the output side of the in-situ supporting wheel group.

[0052] In the present invention, the carrier frame 1 serves as the supporting body of the device. The carrier frame 1 is rotatably provided with two limiting wheels 11 for cooperating with the in-situ driving assembly 2 to assist the rotation of the locomotive wheel set 100. The in-situ driving assembly 2 includes an in-situ driver 21 and two driving wheels 22. The in-situ driver 21 can drive the two driving wheels 22 to rotate, and the two driving wheels 22 are opposite to the two limiting wheels 11 one by one to form an in-situ supporting wheel set. The locomotive wheel set 100 can be placed on the in-situ supporting wheel set and rotated by the driving wheel 22, thereby driving the locomotive wheel set 100 to rotate around its own axis. The limiting wheel 11 rotates together with the locomotive wheel set 100, so that the cleaning system can perform all-round cleaning operations on the locomotive wheel set 100. The stop assembly 3 includes a stop driver 31 and a stop frame 32. The stop driver 31 can drive the stop frame 32 stops the locomotive wheel set 100 from the output side of the in-situ supporting wheel set, so that the locomotive wheel set 100 can be stopped and limited in time after entering the cleaning station, preventing the locomotive wheel set 100 from leaving the cleaning station. The pushing component 4 includes a pushing driver 41 and a pushing rack 42. The pushing driver 41 can drive the pushing rack 42 to push the locomotive wheel set 100 on the in-situ supporting wheel set, and push the locomotive wheel set 100 out of the output side of the in-situ supporting wheel set, so that the cleaned locomotive wheel set 100 can leave the cleaning station without manual pushing. Through the above-mentioned settings, the present application can realize automatic stopping, rotation and pushing of the locomotive wheel set 100, which is convenient for cleaning operations and more efficient. In addition, the present device can be integrated into the automatic cleaning system of the locomotive wheel set 100, and can realize all-round automatic cleaning operations of the locomotive wheel set 100.

[0053] Specifically, the in-situ driver 21 includes a drive assembly, which is connected to a coupling, and a waterproof cover is installed on the outside of the drive assembly to protect the servo motor inside it. The drive assembly drives the drive wheel 22 to rotate around the axis through the coupling, which facilitates the cleaning operation of the locomotive wheel set 100.

[0054] More specifically, since the locomotive wheel set 100 rolls along the locomotive track 200 and moves toward the stop assembly 3, the locomotive wheel set 100 can pass through the pushing assembly 4, the in-situ drive assembly 2 and the stop assembly 3 in sequence, so that the side of the limiting wheel 11 away from the driving wheel 22 is the input side of the in-situ supporting wheel group, and the side of the driving wheel 22 away from the limiting wheel 11 is the output side of the in-situ supporting wheel group. The locomotive wheel set 100 rolls from the input side of the in-situ supporting wheel group to the cleaning station, and after the cleaning operation, it leaves the cleaning station through the output side of the in-situ supporting wheel group.

[0055] The specific structure of the wheelset shifting device is described below:

[0056] Specifically, the in-situ drive assembly 2 also includes an output shaft 23, which is connected to the output end of the in-situ driver 21. Under the drive of the in-situ driver 21, the output shaft 23 rotates around its own axis. Two driving wheels 22 are arranged on the output shaft 23 at intervals. The position of the driving wheel 22 is close to the position of the carrier 1. Through the above arrangement, the driving wheel 22 rotates together with the output shaft 23. The in-situ driver 21 provides power for the locomotive wheel set 100 to rotate around its own axis, which facilitates the automatic cleaning system to clean the locomotive wheel set 100.

[0057] Specifically, the carrier 1 also includes two support plates 12, which provide support for the locomotive wheels 100 to facilitate assembly of the device. The output shaft 23 is rotatably mounted on the two support plates 12, which is beneficial to the stability of the overall structure of the device.

[0058] More specifically, in this embodiment, the support plate 12 is welded to the steel structure of the cleaning chamber and is connected to the in-situ drive assembly 2, the stop assembly 3 and the push assembly 4 by bolts for positioning and assembly. In other embodiments, the above-mentioned components can be connected by other specific structures such as screws, and the support plate 12 can also be connected to the cleaning chamber by other fixed connection methods such as threaded connection. As long as it is convenient to install the device in the cleaning system, no further restrictions will be made here.

[0059] Specifically, the in-situ drive assembly 2 also includes two limit plates 24, which are located between the two drive wheels 22 and rest against the two drive wheels 22 one by one. When the locomotive wheel set 100 is on the in-situ supporting wheel set, the tread of the locomotive wheel set 100 is exactly located between the limit plates 24 and the support plate 12. Through the coordinated action of the limit plates 24 and the support plate 12, the locomotive wheel set 100 will not deviate from the locomotive track 200, further ensuring the limiting effect of this device on the locomotive wheel set 100.

[0060] The cam 322 is provided with a plurality of stop wheels 323, and the cam 323 is provided with a plurality of stop wheels 323. The cam 322 is provided with a plurality of stop wheels 323, and the cam 323 is provided with a plurality of stop wheels 323. The cam 322 is provided with a plurality of stop wheels 323, and the cam 323 is provided with a plurality of stop wheels 323.

[0061] More specifically, the stop frame 32 further includes a first drive arm 324, which is mounted on the stop shaft 321. The stop driver 31 is rotatably mounted on the carrier 1, with its output end rotatably connected to the first drive arm 324. When the stop driver 31 is in operation, the cylinder push rod of the stop driver 31 is rotatably connected to the first drive arm 324. The extension and retraction of the cylinder push rod drives the first drive arm 324 to rotate about the axis of the stop shaft 321, thereby completing the stopping operation of the locomotive wheelset 100. In this embodiment, the stop driver 31 is a pneumatic cylinder. In other embodiments, the stop driver 31 can also be a motor to directly drive the stop shaft 321 to rotate about its own axis.

[0062] Specifically, the pushing frame 42 includes a pushing shaft 421, a pushing arm 422 and a pushing wheel 423, wherein two pushing arms 422 and two pushing wheels 423 are respectively provided, the pushing shaft 421 is rotatably installed on the carrier 1, and the pushing driver 41 is configured to drive the pushing shaft 421 to rotate, and the two pushing arms 422 are arranged on the pushing shaft 421 in parallel and at intervals, and each pushing arm 422 is rotatably provided with a pushing wheel 423, and the two pushing wheels 423 are configured to push the locomotive wheel set 100. After the locomotive wheel set 100 is cleaned, the pushing shaft 421 rotates around the axis under the action of the pushing driver 41, thereby driving the pushing arms 422 and the pushing wheels 423 on the pushing shaft 421 to rotate together, and the pushing wheels 423 gradually approach the locomotive wheel set 100, and the locomotive wheel set 100 is pushed out of the cleaning station through the pushing action of the pushing wheels 423.

[0063] More specifically, the pushing frame 42 further includes a second driving arm 424, which is mounted on the pushing shaft 421. The pushing driver 41 is rotatably mounted on the carrier 1, with its output end rotatably connected to the second driving arm 424. When the pushing driver 41 is operating, the cylinder push rod of the pushing driver 41 is rotatably connected to the second driving arm 424. The extension and retraction of the cylinder push rod drives the second driving arm 424 to rotate about the axis of the pushing shaft 421, thereby completing the pushing operation of the locomotive wheelset 100. In this embodiment, the pushing driver 41 is a cylinder. In other embodiments, the pushing driver 41 can also be a motor that directly drives the pushing shaft 421 to rotate about its own axis.

[0064] More specifically, the stop driver 31 and the push driver 41 both use double-stroke cylinders, which drive the stop shaft 321 and the push shaft 421 to rotate respectively through the extension and retraction of their respective cylinder push rods, thereby completing the stopping and pushing operations of the locomotive wheelset 100, which is convenient for operators to operate, has greater thrust, and saves energy.

[0065] Specifically, the pushing shaft 421 is located between the driving wheel 22 and the limiting wheel 11, and the pushing driver 41 is located on the side of the limiting wheel 11 away from the driving wheel 22, so that the pushing driver 41 can be on the input side of the in-situ supporting wheel group, and push the cleaned locomotive wheel set 100 through the pushing frame 42, so that the locomotive wheel set 100 can leave the device from the output side of the in-situ supporting wheel group. The above arrangement not only conforms to the cleaning process of the locomotive wheel set 100, but also facilitates the automatic cleaning system to perform cleaning operations on the locomotive wheel set 100.

[0066] The embodiment of the present invention also provides a wheel cleaning method, which is convenient for operators to operate and more efficient.

[0067] The following describes the specific steps of this method:

[0068] A wheelset cleaning method, using a cleaning assembly and the wheelset shifting device, comprises:

[0069] Step 1: The stop driver 31 drives the stop frame 32 to the stop state, and the cylinder push rod of the stop driver 31 extends, thereby driving the first driving arm 324 rotatably connected to the cylinder push rod to rotate, so that the stop shaft 321 rotates together, and then drives the stop arm 322 and the stop wheel 323 to rotate toward the driving wheel 22 until the stop wheel 323 reaches the stop position, so that the locomotive wheel set 100 can abut against the stop wheel 323 after entering the cleaning station, thereby playing a stopping and limiting role for the locomotive wheel set 100;

[0070] Step 2: The locomotive wheel set 100 moves along the locomotive track 200 from the input side of the in-situ supporting wheel set to the in-situ supporting wheel set until it abuts against the stop frame 32. The locomotive track 200 is used to limit and guide the rolling direction of the locomotive wheel set 100. When the locomotive wheel set 100 is located between the two driving wheels 22 and the two limiting wheels 11, the tread of the locomotive wheel set contacts the driving wheels 22 and the limiting wheels 11, waiting for the next cleaning operation.

[0071] Step 3: The stop driver 31 drives the stop frame 32 to the unblocked state, and the cylinder push rod of the stop driver 31 is shortened to drive the stop arm 322 and the stop wheel 323 to rotate in the direction away from the driving wheel 22, so that the stop wheel 323 no longer stops the locomotive wheel set 100, and the automatic cleaning system cleans the locomotive wheel set 100. During the cleaning process, the in-situ driver 21 drives the locomotive wheel set 100 to rotate on the in-situ supporting wheel set through the two driving wheels 22. The rotation of the driving wheel 22 drives the locomotive wheel set 100 on the in-situ supporting wheel set to rotate around its own axis. The rotation of the locomotive wheel set 100 drives the limiting wheel 11 to rotate together, thereby facilitating the cleaning system to perform an all-round cleaning operation on the locomotive wheel set 100.

[0072] Step 4: After the locomotive wheel set 100 is cleaned, the pushing driver 41 pushes the locomotive wheel set 100 out from the output side of the original supporting wheel group through the pushing frame 42, and the cylinder push rod of the pushing driver 41 extends, thereby driving the second driving arm 424 rotatably connected to the cylinder push rod to rotate around the axis of the pushing shaft 421, so that the pushing shaft 421, the pushing arm 422 and the pushing wheel 423 rotate toward the locomotive wheel set 100 together, and the locomotive wheel set 100 is pushed by the pushing wheel 423, and the cleaned locomotive wheel set 100 is pushed out of the cleaning station.

[0073] The above-mentioned cleaning component is a conventional mechanism in this field. Its specific structure and working principle refer to the existing technology and will not be described in detail here.

[0074] The present application drives the locomotive wheelset 100 to rotate and shift by direct connection with a motor, and adopts pneumatic elements as actuators for stopping and pushing the locomotive wheelset 100, thereby realizing the integration of stopping, rotating, shifting and pushing of the locomotive wheelset 100, and can adapt to different automatic cleaning operation scenarios of the locomotive wheelset 100.

[0075] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
