Referring to fig. 1 to 3, the present invention provides an automatic recognition apparatus 100. The automatic identification device 100 is applied to a railway wagon wheel pair deruster and is used for identifying whether the bearing 230 exists at the shaft end 211 of the wheel pair 200 or not so as to ensure that the railway wagon wheel pair deruster can derust the wheel pair 200 in a proper derusting mode, avoid the problem of equipment accidents caused by mistakenly identifying the cleaning of the bearing 230 on the wheel pair 200 by the railway wagon wheel pair deruster and ensure the service performance of the equipment.

It can be understood that when the wheel set of the railway wagon is subjected to flaw detection and maintenance, the wheel set needs to be subjected to rust removal and cleaning so as to ensure the accuracy of later-stage flaw detection and maintenance of the wheel set. Some of the wheel sets have bearings, and some of the wheel sets have no bearings. The rust removal mode with the bearings and without the bearings on the wheel pair is different, and if the uniform cleaning mode is adopted, the equipment can be damaged. At present, the device is mainly easy to neglect by identifying through an artificial naked eye mode, and is not beneficial to automation of the device. Therefore, the invention provides a novel automatic identification device 100, and after the automatic identification device 100 is applied to a railway wagon wheel pair deruster, a derusting method can be automatically selected by the railway wagon wheel pair deruster. The specific structure of the automatic recognition apparatus 100 is described in detail below.

In one embodiment, the automatic identification device 100 includes a support assembly 110 and a detection assembly 120. The support assembly 110 is disposed in a preparation station of a railroad truck wheel set rust remover. Sensing assembly 120 is disposed on support assembly 110 for identifying the presence of bearing 230 at axial end 211 of wheel set 200 in the preparation station.

It will be appreciated that the automatic identification device 100 is electrically connected to the controller of the railroad wagon wheel set rust remover. Automatic identification device 100 may detect the presence of bearing 230 at shaft end 211 of wheel set 200 and feed back to the controller. After the controller receives the detection result of the automatic identification device 100, the controller controls the railway wagon wheel pair deruster to select a proper method to derust the wheel pair 200 according to the detection result. When the wheel set 200 is provided with the bearing 230, the controller controls the railway wagon wheel set deruster to derust the axle body 210 of the wheel set 200; when the bearings 230 on wheelset 200 have been removed, i.e., no bearings 230 on wheelset 200, the controller controls the railroad truck wheelset rust remover to remove rust from the axle body 210 and dust cup of wheelset 200.

Detection assembly 120 is an identification component of automatic identification device 100 for determining the presence of bearing 230 at shaft end 211 of wheel set 200. The detection assembly 120 is electrically connected with a controller of the railway wagon wheel pair rust remover, and the detection assembly 120 can feed back a detection result to the controller, so that the controller controls the railway wagon wheel pair rust remover to remove rust of the wheel pair 200 according to an identification result of the detection assembly 120.

The support assembly 110 is a support member of the automatic recognition apparatus 100, and supports the inspection assembly 120 such that the inspection assembly 120 is located at a preparation station. Moreover, the supporting component 110 can support the detecting component 120 off the ground, so that the detecting component 120 is suspended. Thus, after wheel set 200 has been moved to the set-up station, sensing assembly 120 may be positioned over axle end 211 of wheel set 200, opposite axle end 211 of wheel set 200, so that sensing assembly 120 may accurately sense the presence of bearing 230 at axle end 211 of wheel set 200.

Alternatively, the support assembly 110 may be mounted directly on the datum surface of the preparation station. The reference surface may be the ground, the surface of the mounting table, the surface of another component, or the like.

The automatic identification device 100 of the above embodiment detects whether the bearing 230 exists at the shaft end 211 of the wheel pair 200 through the detection component 120, so that the problem of easy negligence existing in the existing identification through the manual naked eye mode is effectively solved, the reliability of the detection of the bearing 230 on the wheel pair 200 can be ensured, and the equipment is prevented from causing accidents. Moreover, after the automatic identification device 100 detects whether the bearing 230 exists on the wheel set 200, the bearing can be fed back to the controller of the railway wagon wheel set deruster, so that the railway wagon wheel set deruster can automatically select a derusting method of the wheel set 200, automatic control is favorably realized, meanwhile, the cost of manpower identification is reduced, and the derusting efficiency is improved.

In an embodiment, the number of the supporting assemblies 110 is two, the number of the detecting assemblies 120 is two, the two supporting assemblies 110 are symmetrically disposed at two sides of the preparation station, and the detecting assemblies 120 are disposed at the corresponding supporting assemblies 110. It will be appreciated that wheel set 200 has an axle body 210 and two wheel portions 220 disposed on axle body 210, and that bearings 230 may be mounted to axle ends 211 of axle body 210. Thus, it is necessary to test both shaft ends 211 of wheel set 200 to determine whether both shaft ends 211 of wheel set 200 have bearings 230.

After the two support assemblies 110 are disposed at the preparation station, the two support assemblies 110 are disposed adjacent to the two shaft ends 211 of the wheel pair 200, and the two detection assemblies 120 are disposed on the corresponding support assemblies 110, respectively. Thus, both axle ends 211 of wheel set 200 may be inspected by correspondingly positioned inspection assembly 120 to determine the presence of bearings 230 at both axle ends 211 of wheel set 200.

Detection assembly 120 detects the presence of bearing 230 at wheelset 200 in three ways, one in which bearing 230 is absent at either axial end 211 of wheelset 200, another in which bearing 230 is present at both axial ends 211 of wheelset 200, and yet another in which bearing 230 is present at one axial end 211 of wheelset 200 and bearing 230 is absent at one axial end 211 of wheelset 200. When no bearing 230 exists at both shaft ends 211 of wheel set 200, the controller removes rust on shaft body 210 and two dust-proof plate seats of wheel set 200 according to the detection result of detection assembly 120. When bearings 230 are present at both shaft ends 211 of wheel-set 200, the controller removes rust from the shaft body 210 of wheel-set 200 based on the detection results. When one shaft end 211 of the wheel pair 200 has the bearing 230 and one shaft end 211 does not have the bearing 230, the controller derusts the shaft body 210 of the wheel pair 200 according to the detection result, and simultaneously derusts the dust-proof plate seat on the side without the bearing 230 and does not derustate the dust-proof plate seat on the side with the bearing 230.

In one embodiment, the detecting assembly 120 includes a size detecting member 122 and a protective housing 121, the protective housing 121 is disposed on the supporting assembly 110, and the size detecting member 122 is disposed in the protective housing 121. Size detector 122 is configured to detect the size of axle end 211 of wheel set 200 to determine the presence of bearing 230 at axle end 211 of wheel set 200.

The shield case 121 has a cavity, and the size detector 122 is disposed in the cavity of the shield case 121. The size detection member 122 is protected by the shield case 121, and the size detection member 122 is prevented from being damaged. The size detection member 122 may be electrically connected to a controller of the railroad truck wheel set rust remover. Size detection member 122 is disposed on shield housing 121, and after shield housing 121 is mounted on the end of support assembly 110, size detection member 122 may correspond to shaft end 211 of wheelset 200 to detect whether bearing 230 is present at shaft end 211 of wheelset 200, and feed back to the controller.

Optionally, the protective housing 121 also has an opening. The opening is provided corresponding to the size detection member 122. In this manner, size detection member 122 may be exposed through the opening to enable detection of axle end 211 of wheel pair 200.

Alternatively, size detector 122 may be a contact-based detector for shaft end 211 of wheel set 200 or a non-contact-based detector for shaft end 211 of wheel set 200.

In one embodiment, size detection component 122 is a laser sensing component that identifies the presence of bearing 230 at shaft end 211 of wheel set 200, or alternatively, a distance from shaft end 211 of wheel set 200, or a diameter size of shaft end 211 of wheel set 200. That is, size detector 122 detects axle end 211 of wheel set 200 in a non-contact manner to determine whether bearings 230 are present at both axle ends 211 of wheel set 200.

Alternatively, the laser sensor may identify whether the bearing 230 is removed or not by using a diameter difference between the axle end 211 of the wheelset 200 with or without the bearing 230 through a generatrix on the side of the bearing 230 in a vertical irradiation manner. The dimensions of the laser sensing element to axle end 211 of wheel-set 200 are fixed for the same model of wheel-set 200. When axle end 211 of wheel set 200 has bearing 230, the laser sensing element is adjusted to the dimensions of axle end 211 of wheel set 200 based on the detection of bearing 230 on wheel set 200. If the laser sensing element does not detect a signal, it indicates that axle end 211 of wheel set 200 does not have bearing 230. If the laser sensor detects a signal, it indicates that axle end 211 of wheelset 200 has bearing 230, as shown in FIGS. 1-3.

As shown in fig. 1 to 3, the dotted line in the drawing is a detection light emitted from the size detection member 122 of the laser sensing member. When the detection light emitted by size detecting member 122 does not strike shaft end 211, it indicates that shaft end 211 of wheel set 200 does not have bearing 230. If the sensing light from size sensing element 122 strikes shaft end 211, it indicates that shaft end 211 of wheelset 200 has bearing 230.

Alternatively, the laser sensing element may detect its distance from shaft end 211. The distance of the optical axis of the wheel pair 200 detected by the laser sensing member is taken as a reference distance by taking the shaft end 211 of the wheel pair 200 as the optical axis as a reference. When identifying whether the bearing 230 exists on the wheelset 200 at a later stage, the judgment is made by the distance from the laser sensing element to the axle end 211 of the wheelset 200. If the laser sensing element detects a dimension of shaft end 211 that is less than the reference distance, it indicates that shaft end 211 of wheelset 200 has bearing 230. If the laser sensing element detects a dimension of shaft end 211 equal to the reference distance, it indicates that shaft end 211 of wheelset 200 does not have bearing 230. Of course, the distance between the shaft end 211 of the wheel pair 200 and the bearing 230 may be used as a reference distance, and the recognition principle is substantially the same as the recognition principle of the optical axis, which is not described herein again.

In other embodiments of the present invention, the laser sensing element may also sense the diameter dimension of shaft end 211. If the diametrical dimension of shaft end 211 is greater than the diametrical dimension of the optical axis, it is an indication that shaft end 211 of wheelset 200 has bearing 230. If the laser sensing element detects a diametric dimension of shaft end 211 equal to the diametric dimension of the optical axis, it indicates that shaft end 211 of wheel set 200 is free of bearing 230.

Optionally, the laser sensing component is a laser distance measuring sensor, a laser distance sensor or other sensing components capable of laser identification, and the like.

Of course, in one embodiment, the detecting assembly 120 further includes a driving power source and a clamping member, the size detecting member 122 is disposed on the clamping member, and the driving power source drives the clamping member to clamp the shaft end 211 of the wheelset 200, so that the size detecting member 122 detects the size of the shaft end 211 of the wheelset 200. That is, the size detecting member 122 detects the diameter size of the shaft end 211 of the wheel pair 200 by contact.

The driving power source drives the clamping member to be disposed in the protective housing 121, and the two clamping arms of the clamping member are respectively provided with a size detection member 122. During detection, the driving power source drives the clamping piece to extend out of the protective shell 121 and move to the shaft end 211 of the wheel pair 200, so that the two clamping arms of the clamping piece are located on two sides of the shaft end 211 of the wheel pair 200, and the size detection piece 122 is abutted to the shaft end 211 of the wheel pair 200. The diameter of axle end 211 of wheelset 200 is sensed by two size sensing members 122.

The presence of bearing 230 at shaft end 211 of wheel set 200 is determined by the diametric dimension of shaft end 211. If bearing 230 is present at shaft end 211 of wheelset 200, then the diametric dimension of shaft end 211 of wheelset 200 is greater than the optical axis dimension of shaft end 211 of wheelset 200. If axle end 211 of wheelset 200 does not have bearing 230, then the diametric dimension of axle end 211 of wheelset 200 is equal to the optical axis dimension of axle end 211 of wheelset 200.

Referring to fig. 1 to 3, in an embodiment, the supporting assembly 110 includes a supporting base 111 and a supporting frame 112 disposed on the supporting base 111, the supporting frame 112 is disposed on the supporting base 111, and the supporting frame 112 carries the detecting assembly 120. The support base 111 may be mounted on a reference surface of the preparation station. The support base 111 is load-bearing for supporting other components of the automatic identification device 100. The bottom of the supporting frame 112 is installed on the supporting base 111, and the top of the supporting frame 112 is connected with the protective shell 121 of the detecting component 120, so as to support the detecting component 120.

The form of the support base 111 is not limited in principle as long as it can be mounted on a reference surface to ensure reliable support. Illustratively, the support base 111 is a support platform or the like.

In one embodiment, the support frame 112 includes a vertical column and a horizontal strut disposed on the vertical column, and the horizontal strut is provided with the detecting assembly 120, such that the detecting assembly 120 is suspended above the shaft end 211 of the wheel pair 200. The vertical upright column is arranged on the supporting base 111 in a vertical mode, one end of the horizontal supporting rod is connected with the vertical upright column, and the other end of the horizontal supporting rod is suspended. The end of the horizontal strut overhang may mount the sensing assembly 120. Alternatively, the supporting frame 112 is made of an aluminum alloy bracket, and of course, the supporting frame 112 may also be made of a steel frame or the like by welding.

Of course, in other embodiments of the present invention, the support frame 112 may be in other forms capable of supporting the detection assembly 120.

In an embodiment, the automatic recognition apparatus 100 further includes an adjustment assembly disposed at the preparation station, and the two support assemblies 110 are movably disposed at the adjustment assembly, and the adjustment assembly is used for adjusting a distance between the two support assemblies 110.

It will be appreciated that different models of wheelsets 200 differ in the size of the two wheel portions 220 and, correspondingly, the distance between the axle ends 211 of the wheelsets 200. After the automatic identification device 100 provided by the invention is additionally provided with the adjusting assemblies, the distance between the two supporting assemblies 110 can be adjusted through the adjusting assemblies, so that the detection assemblies 120 on the supporting assemblies 110 can be aligned to the shaft ends 211 of any wheel pair 200, the identification of any type of wheel pair 200 is facilitated, and the application range is wide.

The bottom portions of the two support members 110 are oppositely disposed on the adjustment member and are movable thereon. The two support assemblies 110 may be moved relative to or away from each other to adjust the distance across the two support assemblies 110. When the two support assemblies 110 move relatively, the two support assemblies 110 approach each other, and the wheelset 200 with a small end distance can be measured; when two support assemblies 110 are moved away from each other, wheel-set 200 can be measured with a large distance between the ends of the two support assemblies 110.

In an embodiment, the adjusting assembly includes an adjusting slide rail and an adjusting slider engaged with the adjusting slide rail, the adjusting slider is disposed at the bottom of the supporting assembly 110, and the supporting assembly can slide along the adjusting slide rail through the adjusting slider. An adjusting slide block is slidably mounted on the adjusting slide rail, the bottom of the adjusting slide block is connected with the bottom of the supporting base 111, and the supporting component 110 slides along the adjusting slide rail through the adjusting slide block, so that the position of the detecting component 120 is adjusted.

Alternatively, the adjustment assembly may manually adjust the position of the detection assembly 120. When wheel pair 200 is overhauled, wheel pair 200 of the same model is overhauled at the same time usually, and at this moment, the position of detection component 120 can be manually adjusted through the adjusting component, so that detection component 120 aligns with shaft end 211 of wheel pair 200, and the accuracy of the detection result is ensured.

Optionally, the adjustment assembly may also automatically adjust the position of the detection assembly 120. Illustratively, the adjusting assembly further comprises a scanning component, an adjusting power source and a screw rod, wherein the output end of the adjusting power source is connected with the screw rod, and the screw rod is connected with two adjusting sliders at the bottoms of the two supporting assemblies 110. Therefore, the adjusting power source drives the two adjusting sliding blocks to be close to or far away from each other through the rotation of the driving screw rod. Optionally, the screw has two sets of opposite threads, so that the two adjusting blocks are close to or far away from each other.

Furthermore, the scanning component and the driving power source are electrically connected with the controller. The scanning component can scan the bar code on the wheel pair 200, identify the model of the wheel pair 200 and feed back to the controller, and the controller controls the driving power source to move according to the scanning result of the scanning component, so that the position of the detection assembly 120 can be automatically adjusted.

After the automatic identification device 100 feeds back the induction result to the controller, the controller sends a next step instruction according to the identification result and a set program, and then a corresponding rust removal mode is selected. Moreover, after the automatic identification device 100 is applied to the railway wagon wheel pair deruster, the situation that the bearing 230 is withdrawn by manual identification can be avoided, the manual selection of a derusting program is avoided, equipment accidents caused by negligence of staff are avoided, and the safety of the equipment is protected to the maximum extent; meanwhile, the controller protects the bearing 230 on the wheel pair 200 according to the recognition feedback of the automatic recognition device 100, and avoids the bearing 230 from being damaged. In addition, the automatic identification device 100 can automatically control the railway wagon wheel pair deruster, improve the production efficiency and reduce the labor intensity of workers.

The invention also provides a railway wagon wheel pair deruster which comprises a controller, a preparation station, a derusting device and the automatic identification device 100 in the embodiment. The controller is electrically connected with a preparation station, a rust removing device and the automatic identification device 100, the automatic identification device 100 is arranged in the preparation station, the preparation station is located on the front side of the rust removing device and used for storing the wheel pair 200 to be cleaned, the automatic identification device 100 identifies whether the bearing 230 exists on the wheel pair 200 and feeds back the bearing to the controller, the controller controls the wheel pair 200 in the preparation station to enter the rust removing device, and the controller controls the rust removing device to remove rust on the wheel pair 200 according to feedback information of the automatic identification device 100.

The preparation station is located at the front end of the rust removal device and is used for storing the wheel pair 200 to be subjected to rust removal. When rust removal is performed, the preparation station pushes the wheel pair 200 into the rust removal device to remove rust, and at the same time, preparation work prepares the next wheel pair 200 to be subjected to rust removal. After the rust removing device finishes removing rust, the rust removing device enables the wheel pair 200 which is well removed with rust to exit from the rust removing device, and then the preparation station pushes the wheel pair 200 to be removed with rust into the rust removing device. The automatic rust removing operation of the wheel set 200 is realized in such a reciprocating way.

After the automatic identification device 100 is added in the preparation station, whether the bearing 230 exists at the shaft end 211 of the wheel set 200 can be prepared by the automatic identification device 100 and fed back to the controller, and the controller controls the rust removal device to remove rust on the wheel set 200 according to the identification result fed back by the automatic identification device 100. When shaft end 211 of wheel set 200 is free of bearing 230, the controller controls the rust removing device to remove rust from shaft body 210 and dust guard seat of wheel set 200. When axle end 211 of wheel set 200 has bearing 230, the controller controls the rust removing device to remove rust from axle body 210 of wheel set 200.

Automatic identification device 100 is arranged behind the preparation station, support assembly 110 is arranged on the datum plane of the preparation station, detection assembly 120 is arranged behind support assembly 110, and detection assembly 120 is positioned above shaft end 211 of wheel pair 200, so that shaft end 211 of wheel pair 200 can be detected.

In an embodiment, the rust removing device comprises a mounting frame, and an axle body rust removing mechanism and two dust plate seat rust removing mechanisms which are arranged on the mounting frame, wherein the axle body rust removing mechanism is used for removing rust on an axle body 210 of the wheel pair 200, and the dust plate seat rust removing mechanism is used for removing rust on a dust plate seat of the wheel pair 200. When the automatic recognition device 100 recognizes that the wheel set 200 has the bearing 230, the controller controls the axle body rust removing mechanism to remove rust from the wheel set 200. When the automatic recognition device 100 recognizes that the wheel set 200 has removed the bearing 230, the controller controls the shaft body rust removing mechanism and the dust plate seat rust removing mechanism to remove rust from the wheel set 200.

The mounting frame is a main body frame of the rust removing device, the shaft body rust removing mechanism is arranged on the mounting frame in a reciprocating motion mode, and the two dust guard seat rust removing mechanisms are symmetrically arranged on the mounting frame and located on two sides of the shaft body rust removing mechanism. The shaft body 210 of the wheel set 200 is derusted by the reciprocating movement of the shaft body derusting mechanism, and two dust plate seats of the wheel set 200 are derusted by the two dust plate seat derusting mechanisms.

The detection component 120 feeds back the condition whether the bearing 230 exists at the shaft end 211 of the wheel pair 200 to the controller, and the controller controls the shaft body rust removing mechanism and the dust plate seat rust removing mechanism to move according to the feedback result. Specifically, when shaft end 211 of wheel pair 200 has bearing 230, the controller controls the shaft body rust removing mechanism to move downward and abut against shaft body 210 of wheel pair 200, and during rust removal, the controller controls the shaft body rust removing mechanism to work and move back and forth along the mounting frame, so as to remove rust on shaft body 210 of wheel pair 200.

When no bearing 230 exists at the end part of the wheel pair 200, the controller controls the shaft body rust removing mechanism to move downwards and abut against the shaft body 210 of the wheel pair 200, and when rust is removed, the controller controls the shaft body rust removing mechanism to work and move back and forth along the mounting rack, so that rust removal on the shaft body 210 of the wheel pair 200 is realized; the controller also controls the dust-proof plate seat rust removal mechanism to move downwards and abut against the dust-proof plate seat of the wheel pair 200, and during rust removal, the controller controls the dust-proof plate seat rust removal mechanism to work so as to remove rust on the end part of the dust-proof plate seat.

Moreover, when no bearing 230 exists at both shaft ends 211 of wheel set 200, the controller controls the two dust plate seat rust removing mechanisms to remove rust on both dust plate seats of wheel set 200. When bearings 230 are arranged at two shaft ends 211 of the wheel pair 200, the controller does not control the two dust guard seat rust removing mechanisms to remove rust. When one shaft end 211 of the wheel pair 200 is provided with the bearing 230 and the other shaft end 211 is not provided with the bearing 230, the controller controls the dust-proof plate seat rust removing mechanism on the side with the bearing 230 not to work and controls the dust-proof plate seat rust removing mechanism on the side without the bearing 230 to remove rust.

In addition, a buffering wheel pushing device 300 is arranged in the preparation station, after the wheel pair 200 to be derusted enters the preparation station, the buffering wheel pushing device 300 is used for buffering the wheel pair 200, so that the wheel pair 200 stops at the preparation station and waits for entering the derusting device. At this time, the automatic recognition device 100 recognizes whether or not the bearing 230 is present at the shaft end 211 of the wheelset 200. When the wheel pair 200 can enter the rust removing device, the buffering wheel pushing device 300 pushes the wheel pair 200 to enter the rust removing device. It should be noted that the buffering push wheel device, the shaft body rust removing mechanism and the dust guard seat rust removing mechanism are all existing structures, and are not described in detail herein.

The invention also provides an identification method of the railway wagon wheel pair deruster, which is applied to the railway wagon wheel pair deruster in the embodiment and comprises the following steps:

if the automatic recognition device 100 detects that the bearing 230 on the wheel set 200 is removed, the controller controls the rust removing device to remove rust from the axle body 210 and the dust-proof plate seat of the wheel set 200.

After the wheel pair 200 enters the preparation station, whether the bearing 230 exists at the shaft end 211 of the wheel pair 200 can be prepared and identified through the detection assembly 120 of the automatic identification device 100 and fed back to the controller, and the controller controls the rust removal device to remove rust on the wheel pair 200 according to the identification result fed back by the automatic identification device 100. When shaft end 211 of wheel set 200 is free of bearing 230, the controller controls the rust removing device to remove rust from shaft body 210 and dust guard seat of wheel set 200. When axle end 211 of wheel set 200 has bearing 230, the controller controls the rust removing device to remove rust from axle body 210 of wheel set 200.

Specifically, the detecting assembly 120 feeds back the condition whether the bearing 230 exists at the shaft end 211 of the wheel pair 200 to the controller, and the controller controls the shaft body rust removing mechanism and the dust plate seat rust removing mechanism to move according to the feedback result.
