Description

Technical Field

[0001] This application relates to the field of vehicle wheelset maintenance technology, and in particular to a dust removal and rust removal machine for bearing cover marking plates and bolts in wheel and axle production lines. Background Technology

[0002] With the continuous improvement of economic levels, the transportation industry is developing rapidly. As a major transportation channel, railways bear important transportation tasks; therefore, the quality of railway freight car wheelset maintenance is particularly important. Due to the long-term, repeated operation of wheelsets, the axle end marking plates and bolts are exposed for extended periods, causing dust, rust, and other foreign matter to accumulate on their surfaces. During maintenance, it is necessary to clean these marking plates and bolts.

[0003] Currently, dust and rust removal on signboards and bolts are typically done manually by workers using brushes or other cleaning tools. However, manual dust and rust removal on signboards and bolts is not only physically demanding for workers, but also poses significant safety hazards due to the large size and weight of wheelsets. Furthermore, manual methods are outdated and cannot be applied to automated wheel and axle production lines, failing to improve automation efficiency with the times. Summary of the Invention

[0004] Based on this, it is necessary to provide a dust removal and rust removal machine for bearing cover marking plates and bolts in wheel and axle production lines to address the aforementioned technical problems.

[0010] In one embodiment, the first driving device drives the first cleaning assembly to rotate about a first rotation axis;

[0017] The number of the second target cleaning areas is configured to be several, and the several second target cleaning areas are distributed around the first target cleaning area. The reciprocating linear motion of the first cleaning component along the first motion trajectory is limited to reciprocating linear motion only within the first target cleaning area.

[0018] In one embodiment, an isolation gap is provided between adjacent second target cleaning areas, the gap width of which is greater than or equal to the diameter of the brush assembly cylinder, and the isolation gap allows the brush assembly cylinder to pass through.

[0019] In one embodiment, the first cleaning device includes:

[0020] A resistance sensor is disposed on the base of the first device and connected to the first cleaning component. The resistance sensor is used to acquire motion resistance information of the first cleaning component when it reciprocates in a straight line along the first motion trajectory.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0058] See Figures 1 to 4 As shown, this application provides a dust removal and rust removal machine for bearing cover marking plates and bolts in a wheel and axle production line, which will be referred to herein as a dust removal and rust removal machine. The dust removal and rust removal machine includes a main base 1000, a positioning device 2000, a first cleaning device 3000, and a second cleaning device 4000. The positioning device 2000 is disposed on the main base 1000 and is used to position the target wheelset 100 to be cleaned on the main base 1000. Therefore, before cleaning the target wheelset 100, the positioning device 2000 can be used to position the target wheelset 100 on the main base 1000, so that the target wheelset 100 is in a suitable position and angle for cleaning operations by the first cleaning device 3000 and the second cleaning device 4000. Those skilled in the art can set the position and angle of the target wheelset 100 on the main base 1000 to a suitable position and angle according to actual needs, which is not limited here.

[0059] See Figure 5 and Figure 6 As shown, the target wheelset 100 comprises two wheels, which are symmetrically mounted at both ends of a central shaft. The two wheels are then combined via a central shaft to form the target wheelset 100. Each wheel has a marker plate and bolts on its outer side wall; these marker plates and bolts represent the target objects that the dust removal and rust removal machine provided needs to clean.

[0060] In one embodiment, the area to which the first cleaning device 3000 is configured for cleaning is defined as a first target cleaning area 110. The first target cleaning area 110 is defined as at least a portion of the surface area of ​​the signboard of the target wheelset 100. That is, the first cleaning device 3000 can be used to clean a portion of the central area of ​​the signboard, or the first target cleaning area 110 can be adjusted to other areas or areas of the signboard as needed, which is not limited here.

[0061] Meanwhile, the second cleaning device 4000 is configured to clean the area of ​​the second target cleaning area 120, which is at least a portion of the surface area of ​​the bolt of the target wheelset 100, with the bolt protruding from the surface of the sign plate. For example, the second cleaning device 4000 can be used to clean the surface area of ​​the bolt head, etc., or the second target cleaning area 120 can be adjusted to other areas or areas of the bolt as needed, which is not limited here.

[0062] like Figure 5 and Figure 6 As shown, the number of second target cleaning areas 120 is configured to be several, that is, the number of bolts installed on the wheel body of the target wheelset 100 is several. Several second target cleaning areas 120 are distributed around the first target cleaning area 110. For example, several bolts are installed on the sign plate so that when the sign plate is fixed to the target wheelset 100 by several bolts, the several bolts are distributed around the circumference of the sign plate. In this case, the first target cleaning area 110 is defined as the central area of ​​the sign plate, which is also the area surrounded by the several bolts on the sign plate. Therefore, the several second target cleaning areas 120 are the surfaces of the bolt heads of the several bolts.

[0063] Continue reading Figure 1 and Figure 3 As shown, the first cleaning device 3000 is movably mounted on the main body base 1000. The movable assembly of the first cleaning device 3000 relative to the main body base 1000 includes, but is not limited to, the ability of the first cleaning device 3000 to move within a three-dimensional space relative to the main body base 1000 in the height, left-right, and front-back directions, allowing it to move to any position within a specific three-dimensional spatial range. The movable assembly of the first cleaning device 3000 relative to the main body base 1000 can be achieved using guiding mechanisms such as height-direction tracks, left-right tracks, and front-back tracks. Alternatively, it is not limited to using other driving mechanical mechanisms such as multi-joint drive arms, hinge mechanisms, and lead screw mechanisms; these are not limited here.

[0064] The first cleaning device 3000 includes a first device base 3100, a first driving device 3200, and a first cleaning assembly 3300. The first driving device 3200 and the first cleaning assembly 3300 are assembled in the first device base 3100. The first cleaning assembly 3300 includes a first cleaning brush body 3310 and a brush body assembly cylinder 3320. The first cleaning brush body 3310 is assembled in the inner cavity of the brush body assembly cylinder 3320, and a portion of the brush body structure of the first cleaning brush body 3310 is exposed at one end of the cylinder of the brush body assembly cylinder 3320. The exposed length can be adjusted as needed, as long as the exposed length is sufficient to clean the first target cleaning area 110.

[0065] The inner diameter of the brush assembly cylinder 3320 can be set to approximately 35 mm, the outer diameter to approximately 37 mm, and the length of the first cleaning brush 3310 to approximately 25 mm. Alternatively, in one embodiment, the brush assembly cylinder 3320 may have an elastic telescopic function. For example, the brush assembly cylinder 3320 can be formed by combining two or more unit cylinders that are elastically connected to each other, or the brush assembly cylinder 3320 can also achieve the elastic telescopic function using a material such as elastic rubber. Therefore, the length of the first cleaning brush 3310 assembled in the brush assembly cylinder 3320 can also be set to be the same. During operation, the first cleaning brush 3310 assembled in the brush assembly cylinder 3320 is in contact with the first target cleaning area 110. Based on the elastic telescopic function of the brush assembly cylinder 3320, part of the brush structure of the first cleaning brush 3310 can be exposed at one end of the cylinder of the brush assembly cylinder 3320.

[0066] The first driving device 3200 is driven to connect with the first cleaning component 3300. The first driving device 3200 can be, for example, a motor of various models or types. The first driving device 3200 is used to drive the first cleaning component 3300 to rotate relative to the first device base 3100. The rotation of the first cleaning component 3300 includes various rotations, including fixed-axis rotation, as long as it meets the cleaning requirements of the first target cleaning area 110. Therefore, the first cleaning component 3300 can be used to clean the first target cleaning area 110 of the target wheelset 100 by its own rotation.

[0067] Continue reading Figure 2 and Figure 4 As shown, the second cleaning device 4000 is movably mounted on the main body base 1000. The movable assembly of the second cleaning device 4000 relative to the main body base 1000 includes, but is not limited to, the ability of the second cleaning device 4000 to move within a three-dimensional space relative to the main body base 1000 in the height, left-right, and front-back directions, allowing it to move to any position within a specific three-dimensional spatial range. The movable assembly of the second cleaning device 4000 relative to the main body base 1000 can be achieved using guiding mechanisms such as height-direction tracks, left-right tracks, and front-back tracks. Alternatively, it is not limited to using other driving mechanical mechanisms such as multi-joint drive arms, hinge mechanisms, and lead screw mechanisms; these are not limited here.

[0068] The second cleaning device 4000 includes a second device base 4100, a second driving device 4200, and a second cleaning assembly 4300, which are mounted on the second device base 4100. The second cleaning assembly 4300 includes a second cleaning brush body 4310 and a brush body mounting base 4320, with the brush body 4310 mounted on the brush body mounting base 4320. The second driving device 4200 is driven to the second cleaning assembly 4300. The second driving device 4200 can be, for example, a motor of various models or types. The second driving device 4200 drives the second cleaning assembly 4300 to rotate relative to the second device base 4100. The rotation of the second cleaning assembly 4300 includes various rotations, including fixed-axis rotation, as long as it meets the cleaning requirements of the second target cleaning area 120. Therefore, the second cleaning assembly 4300 can be used to clean the second target cleaning area 120 of the target wheelset 100 through its own rotation.

[0069] The second cleaning brush body 4310 can be configured as a circular brush body. For example, the outer diameter of the second cleaning brush body 4310 can be set to about 135 mm, the inner diameter of the second cleaning brush body 4310 can be set to about 50 mm, and the length of the second cleaning brush body 4310 can be set to about 35 mm.

[0070] Continue reading Figures 1 to 4 As shown, the main base 1000 serves as the assembly foundation for devices such as the positioning device 2000, the first cleaning device 3000, and the second cleaning device 4000. The main base 1000 can be adapted to the number and structure of devices such as the positioning device 2000, the first cleaning device 3000, and the second cleaning device 4000. For example... Figure 1 and Figure 2 As shown, when the number of the first cleaning device 3000 and the second cleaning device 4000 are both set to two, the main body base 1000 may include a base located in the middle and two columns located at the left and right ends of the base, with the two columns symmetrically arranged on the base.

[0071] Based on the structure of the main base 1000 provided in the above embodiments, the positioning device 2000 can be set on the base in the middle of the main base 1000. Therefore, the target wheelset 100 can be positioned on the base by the positioning device 2000, and the two ends of the target wheelset 100 can correspond to the two columns at the left and right ends of the base respectively. Correspondingly, the two first cleaning devices 3000 and the second cleaning device 4000 can be set on the two columns at the left and right ends of the base respectively. That is, a first cleaning device 3000 and a second cleaning device 4000 are movably mounted on each column, so that the two ends of the target wheelset 100 can perform the cleaning operation of the first target cleaning area 110 and the second target cleaning area 120 through the first cleaning device 3000 and the second cleaning device 4000 on their respective columns.

[0072] like Figure 7 and Figure 8 As shown, after the target wheelset 100 is positioned on the main body base 1000, the first cleaning device 3000 can move relative to the main body base 1000 based on its movable assembly on the main body base 1000, and then move to the position corresponding to the first target cleaning area 110 of the target wheelset 100. At this time, the first driving device 3200 of the first cleaning device 3000 can drive the first cleaning assembly 3300 to rotate, and clean the first target cleaning area 110 through the first cleaning brush body 3310 of the first cleaning assembly 3300.

[0073] In one embodiment, the first driving device 3200 drives the first cleaning assembly 3300 to rotate along a first rotation axis, that is, the first cleaning brush body 3310 of the first cleaning assembly 3300 cleans the first target cleaning area 110 by rotating along the fixed axis. Alternatively, the first cleaning device 3000 may also include a composite driving assembly, which is mounted on the first device base 3100. In this case, the first driving device 3200 is indirectly mounted on the first device base 3100 through the composite driving assembly, and the composite driving assembly can be used for driving connection with the first driving device 3200.

[0074] Since the first driving device 3200 is driven to the first cleaning component 3300, the composite driving component can be used to drive the first driving device 3200 and the first cleaning component 3300 to rotate synchronously along the first rotation axis. The speed at which the composite driving component drives the first driving device 3200 and the first cleaning component 3300 to rotate synchronously along the axis is defined as the first speed, and the speed at which the first driving device 3200 drives the first cleaning component 3300 to rotate along the axis is defined as the second speed. At this time, it is necessary to limit the first speed to be less than the second speed.

[0075] The purpose of the composite drive assembly driving the first drive device 3200 and the first cleaning component 3300 to rotate synchronously on a fixed axis is for circumferential rotation. The purpose of the first drive device 3200 driving the first cleaning component 3300 to rotate on a fixed axis is to press the first cleaning brush body 3310 against the target wheelset 100 through high-speed rotation, thereby achieving the cleaning operation of the first target cleaning area 110. Therefore, the first rotational speed can be several or tens of times less than the second rotational speed, depending on the requirements, and is not limited here.

[0076] Simultaneously, the composite drive assembly drives the first drive device 3200 and the first cleaning component 3300 to reciprocate along a first motion trajectory, and the first motion trajectory is not parallel to the first rotation axis. For example, the first motion trajectory forms a suitable angle with the first rotation axis in space. Therefore, by synchronously driving the first drive device 3200 and the first cleaning component 3300 through the composite drive assembly, two different motion states can be superimposed on the first drive device 3200 and the first cleaning component 3300 at the same time, so that the first drive device 3200 and the first cleaning component 3300 can rotate circumferentially and reciprocate radially at the same time. During this process, the first cleaning component 3300 will also be controlled by the first drive device 3200 to rotate in a fixed-axis rotation state. This fixed-axis rotation state does not interfere with the superimposed motion of circumferential rotation and radial reciprocating motion mentioned above, so that the entire actual motion presents a composite motion of two fixed-axis rotations and reciprocating motions with different speeds.

[0077] In one embodiment, the first motion trajectory lies in a plane, and the first rotation axis is perpendicular to the plane containing the first motion trajectory. In this case, the first motion trajectory can be a curved motion within the plane. Alternatively, the first motion trajectory is a straight line trajectory, and the first rotation axis is perpendicular to the first motion trajectory. The composite drive component drives the first cleaning component 3300 to reciprocate linearly along the first motion trajectory. In this case, the actual motion of the first cleaning component 3300 is a composite motion of fixed-axis rotation and reciprocating linear motion.

[0078] Furthermore, in one embodiment, the composite drive assembly may include a third drive device and a fourth drive device. For example, the third drive device may be used to drive the first drive device 3200 and the first cleaning component 3300 to rotate synchronously along a first rotation axis. The rotational speed at which the third drive device drives the first drive device 3200 and the first cleaning component 3300 to rotate synchronously along the axis is defined as a first rotational speed, and the rotational speed at which the first drive device 3200 drives the first cleaning component 3300 to rotate along the axis is defined as a second rotational speed. In this case, the first rotational speed needs to be limited to being less than the second rotational speed. Simultaneously, the fourth drive device is used to drive the first drive device 3200 and the first cleaning component 3300 to reciprocate along a first motion trajectory.

[0079] In this embodiment, both the third and fourth driving components can be mounted on the first device base 3100. The third driving component is drivenly connected to the first driving component 3200, and the fourth driving component is drivenly connected to the third driving component. The third driving component is indirectly mounted on the first device base 3100 via the fourth driving component, and the first driving component 3200 is indirectly mounted on the first device base 3100 via both the third and fourth driving components. The third driving component drives the first driving component 3200 and the first cleaning component 3300 to rotate synchronously on a fixed axis, while the fourth driving component drives the three components—the third driving component, the first driving component 3200, and the first cleaning component 3300—to reciprocate synchronously.

[0080] See Figure 7 and Figure 8 As shown, when the first cleaning component 3300 performs a cleaning operation on the first target cleaning area 110 by rotating on a fixed axis, the third driving device drives the first driving device 3200 and the first cleaning component 3300 to rotate synchronously on a fixed axis, so that the first driving device 3200 and the first cleaning component 3300 rotate circumferentially at a slower first speed. At the same time, the fourth driving device drives the third driving device, the first driving device 3200 and the first cleaning component 3300 to reciprocate synchronously, so that the third driving device, the first driving device 3200 and the first cleaning component 3300 reciprocate synchronously along the radial direction.

[0081] This control method allows the first cleaning component 3300 to have three superimposed motion states. The first motion state is that the first cleaning component 3300 rotates at a relatively fast first speed on a fixed axis to perform cleaning operations on the first target cleaning area 110. The second motion state is that the first cleaning component 3300 rotates circumferentially at a relatively slow first speed. The third motion state is that the first cleaning component 3300 reciprocates along the radial direction. Therefore, under the superimposed effect of the second and third motion states, the first cleaning component 3300 can continuously change the contact position within the first target area, fully clean the first target cleaning area 110, and increase the cleaning area of ​​the first target cleaning area 110.

[0082] Because the first cleaning component 3300 can continuously change its contact position within the first target area under the superposition of the second and third motion states, the reciprocating linear motion of the first cleaning component 3300 along the first motion trajectory in the above control method needs to be limited to reciprocating linear motion only within the first target cleaning area 110. This limitation can be defined by a program or by physical contact. For example, in one embodiment, there is an isolation gap 130 between adjacent second target cleaning areas 120. The gap width of the isolation gap 130 is smaller than the diameter of the brush assembly cylinder 3320. Therefore, when the brush assembly cylinder 3320 contacts the bolt of the second target cleaning area 120, the bolt will restrict the brush assembly cylinder 3320, and the smaller gap width of the isolation gap 130 can be used to prevent the brush assembly cylinder 3320 from passing through. Therefore, the brush assembly cylinder 3320 can only be limited to the first target cleaning area 110, thereby limiting the movement of the first cleaning component 3300 only within the first target cleaning area 110.

[0083] In addition, when there is an isolation gap 130 between adjacent second target cleaning areas 120, the width of the isolation gap 130 can be limited to be greater than or equal to the diameter of the brush assembly cylinder 3320. This allows the brush assembly cylinder 3320 to pass through, and thus the brush assembly cylinder 3320 can also be allowed to enter the isolation gap 130 between adjacent second target cleaning areas 120 to clean that area and expand the cleaning range. The width of the isolation gap 130 can be limited to 45mm.

[0084] Those skilled in the art can choose an appropriate method to set the relationship between the gap width of the isolation gap 130 and the diameter of the brush body assembly cylinder 3320 according to actual needs, thereby achieving different cleaning effects, which are not limited here.

[0085] During this process, since the first cleaning brush body 3310 is located in the brush body assembly cylinder 3320, the first cleaning brush body 3310 will not get caught on the bolts of the second target cleaning area 120 when cleaning the first target cleaning area 110.

[0086] In addition, in one embodiment, the first cleaning device 3000 may further include a resistance sensor and a first controller. The resistance sensor is disposed on the first device base 3100 and connected to the first cleaning component 3300. The resistance sensor is used to acquire motion resistance information encountered by the first cleaning component 3300 when it reciprocates linearly along a first motion trajectory. The first controller is connected to the resistance sensor and the composite drive component. The first controller is used to generate motion control information based on the motion resistance information, and to control the composite drive component's drive of the first drive device 3200 and the first cleaning component 3300 based on the motion control information. Thus, through the data and control coordination of the resistance sensor and the first controller, the first cleaning component 3300 can be actively controlled to move only within the first target cleaning area 110.

[0087] In one embodiment, the motion resistance information includes real-time resistance values, and the reciprocating linear motion of the first cleaning component 3300 along the first motion trajectory includes forward linear motion and reverse linear motion with opposite directions of motion. Specifically, the movement of the first cleaning component 3300 from the first target cleaning area 110 towards the second target cleaning area 120 is forward linear motion, i.e. Figure 6 The bolts shown move radially from the center of the signboard toward the outer periphery, while the first cleaning assembly 3300 moves in a reverse linear motion from the second target cleaning area 120 toward the first target cleaning area 110.

[0088] The real-time resistance value represents the real-time resistance experienced by the first cleaning component 3300. When the first cleaning component 3300 is not in contact with the bolt, the resistance experienced by the first cleaning component 3300 is small, mainly due to the frictional force experienced by the first cleaning component 3300 when cleaning the first target cleaning area 110. However, when the real-time resistance value is greater than or equal to the preset resistance peak value, it indicates that the resistance experienced by the first cleaning component 3300 has increased. This is not only due to the frictional force experienced by the first cleaning component 3300 when cleaning the first target cleaning area 110, but also mainly because the first cleaning component 3300 has come into contact with the bolt, and the bolt prevents the first cleaning component 3300 from continuing radial movement. At this time, the first controller is used to control the composite drive component to drive the first drive device 3200 and the first cleaning component 3300 according to the motion control information, so that the composite drive component drives the first drive device 3200, which is performing forward linear motion, and the first cleaning component 3300 to simultaneously perform reverse linear motion.

[0089] In one embodiment, the dust removal and rust removal machine includes a motion base 5000, which is movably mounted on a main body base 1000. The main body base 1000 defines a first reference plane and a second reference plane, which are perpendicular to each other. The first reference plane can be used to represent a reference plane parallel to a horizontal plane, and the second reference plane can be used to represent a reference plane perpendicular to a horizontal plane (or parallel to a vertical plane).

[0090] The positioning device 2000 is used to position the target wheelset 100 so that the central axis of the target wheelset 100 is simultaneously parallel to the first reference plane and the second reference plane, that is, the central axis of the target wheelset 100 is simultaneously parallel to the horizontal plane and the vertical plane. The motion base 5000 is used to move in a plane parallel to the second reference plane, that is, the motion base 5000 moves in a plane perpendicular to the horizontal plane (or parallel to the vertical plane) and moves in height.

[0091] The dust removal and rust removal machine also includes a first linear track 5100 and a second linear track 5200, as well as a third linear track (not shown) and a fourth linear track (not shown) that cooperate with it. The first cleaning device 3000 is mounted on the motion base 5000 via the first linear track 5100 and the third linear track. The first linear track 5100 is parallel to the first reference plane and perpendicular to the second reference plane. The third linear track is perpendicular to the first linear track. The first cleaning device 3000 reciprocates linearly along the first linear track 5100, and the third linear track reciprocates linearly along the first linear track 5100. At this time, the first cleaning device 3000 can move forward and backward and left and right in three-dimensional space based on the first linear track 5100 and the third linear track, thereby moving closer to or away from the target wheelset 100.

[0092] The second cleaning device 4000 is mounted on the motion base 5000 via a second linear track 5200 and a fourth linear track. The second linear track 5200 is parallel to the first reference plane and perpendicular to the second reference plane. The fourth linear track is perpendicular to the second linear track 5200. The second cleaning device 4000 reciprocates linearly along the second linear track 5200, and the fourth linear track reciprocates linearly along the second linear track 5200. At this time, the second cleaning device 4000 can move forward and backward and left and right in three-dimensional space based on the second linear track 5200 and the fourth linear track, thereby moving closer to or away from the target wheelset 100.

[0093] In one embodiment, the dust removal and rust removal machine includes a positioning device 5300 and a second controller. The positioning device 5300 is disposed on the motion base 5000 and is used to make positioning contact with the target wheelset 100 to be cleaned. The positioning device 5300 generates positioning contact information when it makes positioning contact with the target wheelset 100. For example, the positioning device 5300 may also be a contact sensor; when the positioning device 5300 makes positioning contact with the target wheelset 100, it indicates that the motion base 5000 has moved into position. The second controller is connected to the positioning device 5300 and the motion base 5000. The second controller is used to control the motion base 5000 to move in a plane parallel to the second reference plane according to the positioning contact information. For example, when the positioning contact information indicates that the motion base 5000 has moved to the correct position, the second controller stops the movement of the motion base 5000. Otherwise, it continues to move in the preset direction, so that the motion base 5000 moves to the preset target position, aligns the first cleaning device 3000 and the second cleaning device 4000 with the target wheelset 100, and prepares to carry out the cleaning operation.

[0094] In one embodiment, the positioning device 2000 includes a moving component 2100 and a fixing component 2200. The moving component 2100 is mounted on the main body base 1000 and reciprocates on the main body base 1000 along a wheelset translation trajectory. The wheelset translation trajectory is a straight line trajectory, wherein the wheelset translation trajectory is parallel to a first reference plane and perpendicular to a second reference plane, and the wheelset translation trajectory is parallel to the central axis of the target wheelset 100. The fixing component 2200 is disposed on the moving component 2100 and is used to fix the target wheelset 100 to be cleaned.

[0095] As described above, the dust removal and rust removal machine includes a first cleaning device 3000 and a second cleaning device 4000. The first cleaning device 3000 performs rust removal on the marking plate area, while the second cleaning device 4000 performs rust removal on the bolts. Furthermore, both the first cleaning device 3000 and the second cleaning device 4000 have a mobile operation function, enabling them to self-position according to the wheelset height. They can adapt to different wheelset heights and positioning dimensions. By switching cleaning device positions, the machine ensures that both the first cleaning device 3000 and the second cleaning device 4000 are aligned with the wheelset's central axis, allowing for automatic rust removal on different wheelsets and bolt positions, maximizing the rust removal area, and thus automatically completing the dust removal and rust removal operations on the marking plates and bolts.

[0096] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
