Description

Technical Field

[0001] This invention relates to the technical field of out-of-roundness detection, and more particularly to a wheelset assembly wear detection system and a train inspection station. Background Technology

[0002] Wheelset inspection of railcars is a crucial measure to ensure the safe, reliable, economical, and compliant operation of trains. To guarantee inspection efficiency and accuracy, inspection devices are typically used to inspect the wheelsets. However, because the train wheels are located at the bottom of the train and are in close contact with the track, they obstruct the inspection process, making it impossible to guarantee inspection accuracy.

[0003] Patent CN219523906U discloses a wheelset flange and tread wear detection device. In use, the mounting part is first installed on the outside of the bearing and in the tread. Then, the first sliding part and sensor are connected to the mounting part. The sensor is adjusted and positioned by the extension or rotation of the first connecting plate and the second connecting plate. The first sensor faces the tread of the wheelset, and the second sensor faces the flange of the wheelset. By sliding the second sliding part in the annular groove, the first sensor detects the rotation of the tread of the wheelset around one circumference, and the second sensor detects the rotation of the flange of the wheelset around one circumference. Once installed, the rotation of the tread and flange of the wheelset can be detected around one circumference.

[0004] It is evident that this technical solution is a detection method that establishes direct contact with the wheelset. The detection process includes the installation and disassembly of the detection device, both of which consume a significant amount of time, resulting in low detection efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a wheelset component wear detection system and a train inspection station, which solves the technical problem of low detection efficiency of the detection devices in the prior art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0009] In a first aspect, the present invention provides a wheelset assembly wear detection system. The wheelset assembly includes a connecting shaft extending in a front-rear direction and wheelsets fixedly connected to both ends of the connecting shaft. The system includes a coupling device, a measuring module, and a base. Both the coupling device and the measuring module are supported on the base, and a vertically extending abutment portion is formed on the coupling device. The coupling device and the base can slide and switch between an initial position and an end position in a left-right direction. When the wheelset assembly rolls in a left-right direction, the connecting shaft can push the abutment portion, thereby causing the coupling device to slide and switch from the initial position to the end position, so that the measuring module can detect the out-of-roundness of the wheelset when the wheelset rotates.

[0010] Secondly, the present invention provides a train inspection station, including the wheelset component wear detection system in the above technical solution, and also includes two second tracks extending in the left and right directions, with the wheelset correspondingly and rollingly connected to the second tracks, the second tracks being the train's running track, and the wheelset component wear detection system being located between the two sets of second tracks.

[0011] (III) Beneficial Effects

[0012] The beneficial effects of the present invention are as follows: The wheelset assembly wear detection system of the present invention can realize the out-of-roundness detection of the wheelset by pushing the abutment part to drive the base and the measuring module supported on the base to run synchronously. The whole process does not include the connection process between the device and the wheelset assembly, thus greatly simplifying the out-of-roundness detection process of the wheelset and improving the detection efficiency of the wheelset.

[0039] To better explain and facilitate understanding of this invention, the following description is provided in conjunction with the appendix. Figures 1-10The present invention will be described in detail through specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0040] Example 1:

[0041] Reference Figures 1-10 An embodiment of the present invention provides a wheelset assembly wear detection system. The wheelset assembly 100 includes a connecting shaft 101 extending in the front-rear direction and wheelsets 102 fixedly connected to both ends of the connecting shaft 101. The system includes a coupling device 1, a measuring module 2, and a base 3. Both the coupling device 1 and the measuring module 2 are supported on the base 3, and a vertically extending abutment portion A is formed on the coupling device 1. The coupling device 1 and the base 3 can slide and switch between an initial position and an end position in the left-right direction. When the wheelset assembly 100 rolls in the left-right direction, the connecting shaft 101 can push the abutment portion A, thereby causing the coupling device 1 to slide and switch from the initial position to the end position, so that the measuring module 2 can detect the out-of-roundness of the wheelset 102 when the wheelset 102 rotates.

[0042] In this embodiment, the wheelset 102 is fixedly connected to both ends of the connecting shaft 101 and is the part that actually contacts the track and bears wear. The base 3 serves as the support structure for the entire system, ensuring the stability and accuracy of each component. The engaging device 1 is supported on the base 3 and has a vertically extending abutment portion A.

[0043] The specific testing process is as follows: With the coupling device 1 in its initial position and the measuring module 2 ready, when the wheelset assembly 100 rolls in the left-right direction, the connecting shaft 101 contacts the abutment portion A of the coupling device 1. The pushing force of the connecting shaft 101 causes the coupling device 1 to slide from its initial position. Driven by the connecting shaft 101, the coupling device 1 gradually slides to its final position, allowing the measuring module 2 to move synchronously with the wheelset assembly 100 in the left-right direction. Thus, the measuring module 2 can detect the out-of-roundness of the wheelset 102 in real time. By limiting the displacement of the wheelset assembly 100 from its initial to its final position to be greater than the circumference of the wheelset 102, the measuring module 2 can complete the out-of-roundness detection of the wheelset 102.

[0044] Since the connecting shaft 101 can drive the base 3 and the measuring module 2 supported on the base 3 to run synchronously by pushing the abutment part A, thereby realizing the out-of-roundness detection of the wheelset 102, the whole process does not include the connection process between the device and the wheelset assembly 100, thus greatly simplifying the out-of-roundness detection process of the wheelset 102 and improving the detection efficiency of the wheelset 102.

[0045] Specifically, the measurement module 2 is set as a laser sensor, which emits light signals to the wheelset 102 to detect the wear of the wheelset 102.

[0046] Example 2:

[0047] Reference Figures 1-10 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0048] The abutment A is hinged to the base 3 in the front-to-back direction, so that the abutment A can swing between the use angle and the clearance angle. The detection system also includes an angle control device 4, which can switch between a locked state that restricts the swing of the abutment A relative to the base 3 and a released state that allows the abutment A to swing relative to the base 3. When the angle control device 4 is switched to the locked state, the abutment A maintains the use angle, and the connecting shaft 101 can push the abutment A and thus drive the engagement device 1 to slide from the initial position to the end position, so that the measuring module 2 can detect the out-of-roundness of the wheelset 102 when the wheelset 102 rotates. When the abutment A, under the push of the connecting shaft 101, causes the engagement device 1 to slide to the end position, the angle control device 4 can switch to the released state, so that the abutment A can switch to the clearance angle under the push of the connecting shaft 101, so that the wheelset assembly 100 can continue to roll and pass over the abutment A.

[0049] In this embodiment, the abutment A is hinged to the base 3 in the front-to-back direction. This design allows the abutment A to swing freely between the use angle and the clearance angle. The use angle is the fixed angle when the abutment A is in normal contact with the wheelset 102 for measurement. At this time, the abutment A can drive the base 3 and the measurement module 2 on the base 3 to run synchronously under the push of the connecting shaft 101, completing the out-of-roundness detection of the wheelset 102. The clearance angle is the angle at which the abutment A is opened, allowing the wheelset assembly 100 to continue rolling without obstruction. This corresponds to the state after the detection work is completed. By switching the abutment A to the clearance angle, the wheelset assembly 100 can continue to roll continuously, so as not to affect the normal operation of the wheelset assembly 100, thereby further improving the detection efficiency.

[0050] The angle control device 4 has two operating modes: a locked state and a released state. In the locked state, the abutment part A is fixed at the operating angle and cannot swing freely, ensuring the stability and accuracy of the measurement process. In the released state, the abutment part A can swing freely to the clearance angle, allowing the wheelset 102 to roll smoothly. When the angle control device 4 switches to the locked state, the abutment part A maintains the operating angle. At this time, the connecting shaft 101 pushes the abutment part A, thereby driving the engagement device 1 to slide from the initial position to the end position, so that the measurement module 2 can detect the out-of-roundness of the wheelset 102 while the wheelset 102 is rotating.

[0051] When the engagement device 1 slides to the end position under the push of the connecting shaft 101, that is, after the measurement is completed, the angle control device 4 automatically or manually switches to the release state. In the release state, the abutment part A swings to the clearance angle under the push of the connecting shaft 101, allowing the wheelset 102 to continue rolling and pass over the abutment part A.

[0052] In this embodiment, the hinged design of the contact part A, combined with the angle control device 4, ensures that the monitoring system does not affect the continued rolling of the wheelset assembly 100 after the detection is completed, thus improving the flexibility of use.

[0053] Example 3:

[0054] Reference Figures 1-10 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0055] The engagement device 1 includes a mounting frame 11 and a roller assembly 12. The roller assembly 12 is rotatably connected to the mounting frame 11 in the front-back direction. The mounting frame 11 is hinged to the base 3 in the front-back direction. The roller assembly 12 forms an abutment portion A. The roller assembly 12 includes at least one roller. When the abutment portion A is in the use angle and the connecting shaft 101 pushes the abutment portion A and moves the engagement device 1 left and right, the roller remains tangent to the connecting shaft 101. The engagement device 1 also includes a reset member. The reset member stores force when the engagement device 1 switches from the use angle to the yield angle, so as to provide the engagement device 1 with a reset force for switching from the yield angle to the use angle.

[0056] In this embodiment, the engagement device 1 includes a mounting frame 11 and a roller assembly 12. The roller assembly 12 is rotatably connected to the mounting frame 11 in the front-to-back direction, forming an abutment portion A. The mounting frame 11 is hinged to the base 3 in the front-to-back direction, allowing the engagement device 1 to swing between a working angle and a clearance angle.

[0057] The roller assembly 12 includes at least one roller that can rotate freely. When the contact part A is at the operating angle and the connecting shaft 101 pushes the contact part A to move the engagement device 1 left and right, the roller remains tangent to the connecting shaft 101, ensuring the stability and accuracy of the transmitted thrust. It also allows the connecting shaft 101 to maintain rolling contact with the contact part A, reducing the frictional loss of the connecting shaft 101 and improving the smoothness of the detection process.

[0058] The engagement device 1 also includes a reset element, such as a torsion spring. When the engagement device 1 needs to switch from the yield angle back to the use angle, the reset element releases the stored force to provide a reset force, so that the engagement device 1 can quickly and accurately return to the use angle for the next test, which helps to improve the testing efficiency.

[0059] Specifically, the engagement device 1 also includes a rotatably connected to the mounting frame 11. When the connecting shaft 101 engages with the roller, the idler roller contacts the connecting shaft 101 from below, which helps to improve the stability of the engagement device 1 when switching positions.

[0060] Example 4:

[0061] Reference Figures 1-10 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0062] The detection system also includes a limiting device 5, which can limit the joint device 1 from sliding away from the initial position to the end position when the joint device 1 slides from the initial position to the end position.

[0063] In this embodiment, the limiting device 5 is used to limit the range of movement of the engaging device 1 during the sliding process.

[0064] When the engagement device 1 slides from the initial position to the end position, the limiting device 5 can function to prevent the engagement device 1 from continuing to slide away from the initial position. In this way, the wheelset assembly 100 continues to roll. After the angle control device 4 switches to the released state, the abutment part A can switch to the yield angle under the push of the connecting shaft 101, allowing the wheelset assembly 100 to continue rolling and pass over the abutment part A, thus avoiding affecting the continuous operation of the wheelset assembly 100.

[0065] Specifically, the limiting device 5 can be a mechanical stop, and the limiting device 5 includes a spring, a baffle and a buffer pad. One end of the spring is fixedly supported on a predetermined frame, and the other end of the spring is connected to the baffle. The buffer pad is connected to the side wall of the baffle facing the base 3 to absorb the impact from the base 3.

[0066] In this embodiment, the limiting device 5, together with the abutment part A and the angle control device 4, can push the abutment part A with the connecting shaft 101 after the engaging device 1 has slid to the end position and the angle control device 4 has switched to the released state, so that the abutment part A can be switched to the yielding angle, ensuring that the wheelset assembly 100 can operate continuously without interference.

[0067] Example 5:

[0068] Reference Figures 1-10 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0069] The angle control device 4 includes a locking assembly 41 and a control assembly 42. The locking assembly 41 includes a support 411, a locking block 412, and a locking seat 413. The support 411 is fixedly connected to the base 3. The locking block 412 is slidably mounted on the support 411 in the front-to-back direction. The locking seat 413 is fixedly connected to the mounting bracket 11, and a locking groove F is provided on the locking seat 413. The locking block 412 can switch between a limited state that engages with the locking groove F and a released state that disengages from the locking groove F. The locking assembly 41 also includes a first elastic element 414, which stores force when the locking block 412 switches from the limited state to the released state, so as to provide a restoring force for the locking block 412 to switch from the released state to the limited state. The control assembly 42 includes a control bracket. 421, the control frame 421 is slidable relative to the support 411 in the left-right direction. A first pushing part B is formed on the control frame 421, which can compress the locking block 412. A second pushing part C is formed on the locking block 412. The control frame 421 can drive the first pushing part B to switch between a compressing state that pushes the second pushing part C and a separating state that moves away from the second pushing part C. When the first pushing part B continuously pushes the second pushing part C, the locking block 412 can switch from a limiting state to a releasing state. The second pushing part C is set as an inclined surface. The control assembly 42 also includes a second elastic member 422. The second elastic member 422 stores force when the control frame 421 switches from a separating state to a compressing state, so as to provide the control frame 421 with a restoring force for switching from a compressing state to a separating state.

[0070] In this embodiment, the angle control device 4 includes a snap-fit ​​component 41 and a control component 42, which are used to control the locking and unlocking states of the engagement device 1.

[0071] The locking block 412 can switch between a limited state, engaging with the slot F, and a released state, disengaging from the slot F. In the limited state, the locking block 412 engages with the slot F, fixing the engagement device 1 at the operating angle. In the released state, the locking block 412 disengages from the slot F, and the engagement device 1 can freely swing to the clearance angle. The first elastic member 414 stores force when the locking block 412 switches from the limited state to the released state, providing a restoring force for the locking block 412 to switch from the released state to the limited state.

[0072] The control frame 421 can drive the first pushing part B to switch between a pressing state that compresses the second pushing part C and a separating state that moves away from the second pushing part C. When the first pushing part B continuously pushes the second pushing part C, the locking block 412 can switch from a limiting state to a releasing state. The second elastic member 422 stores force when the control frame 421 switches from the separating state to the pressing state, providing the control frame 421 with a restoring force for switching from the pressing state to the separating state.

[0073] When the engagement device 1 is in the operating angle, the control frame 421 is in the separated state, the first elastic element 414 pushes the locking block 412 into the locking slot F to achieve the limiting state, and the engagement device 1 is fixed at the operating angle, ready for measurement.

[0074] When the engagement device 1 needs to be switched to the clearance angle, the external force pushes the control frame 421 to the compression state. At this time, the first pushing part B squeezes the second pushing part C, causing the locking block 412 to disengage from the locking groove F and achieve the release state. The abutting part A of the engagement device 1 swings to the clearance angle under the push of the connecting shaft 101.

[0075] After the wheelset assembly 100 passes the abutment portion A, the abutment portion A will be reset to the operating angle under the action of the reset member. Furthermore, when the reset force of the reset member can overcome the external force applied to the control frame 421, the locking assembly 41 can switch to the limit state, thereby limiting the abutment portion A to the operating angle.

[0076] Specifically, the second pushing part C is an inclined surface facing the first pushing part B. Not only can the first abutting part A push the inclined surface to compress the second elastic member 422, but during the process of switching from the yielding angle to the use angle while abutting part A is in contact with the inclined surface, the card seat, which is fixed in a position relative to the abutting part A, can also push the inclined surface to compress the second elastic member 422, thereby enabling the card block 412 to re-establish a cooperative relationship with the card slot F.

[0077] More specifically, the side wall of the card slot F is provided on the card holder 413 so that when the abutment part A is switched to the use angle, the side wall of the card holder 413 faces the card block 412 so that the card slot F can cooperate with the card block 412. The edge of the card holder 413 forms a third pushing part D that can push the second pushing part C.

[0078] Example 6:

[0079] Reference Figures 1-10 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0080] The detection system also includes a pressing device 6 and a hinge seat 13. The pressing device 6 includes a push plate 61 and a third elastic element 62. The mounting frame 11 is hinged to the base 3 via the hinge seat 13, and the mounting frame 11 and the hinge seat 13 are slidably connected in the left-right direction so that the mounting frame 11 can switch between abutting and pushing state and abutting and fixing state. The push plate 61 is fixedly connected to the mounting frame 11. When the mounting frame 11 switches from the abutting and fixing state to the abutting and pushing state under the drive of the abutting part A, the push plate 61 can press the control frame 421 so that the control frame... 421 switches from the separation state to the compression state; the third elastic member 62 can store force when the mounting frame 11 switches from the abutting fixed state to the abutting pushing state, so as to provide the mounting frame 11 with the reset force for switching from the abutting pushing state to the abutting fixed state; when the mounting frame 11 is in the abutting fixed state, the connecting shaft 101 can push the abutting part A to make the engaging device 1 slide; when the limiting device 5 restricts the movement of the engaging device 1, and the connecting shaft 101 continues to push the abutting part A, the mounting frame 11 switches from the abutting fixed state to the abutting pushing state.

[0081] In this embodiment, under normal circumstances, that is, when the engaging device 1 is not restricted from moving, the connecting shaft 101 pushes the abutment part A, and the abutment part A and the mounting bracket 11 are fixed. When the force cannot overcome the elastic force of the third elastic member 62, the mounting bracket 11 remains in the abutment fixed state. At the same time, the mounting bracket 11 will drive the engaging device 1 to slide. During this process, the measuring module 2 can detect the out-of-roundness of the wheelset 102.

[0082] When the engagement device 1 is restricted from moving, the connecting shaft 101 continues to push the abutment part A. The abutment part A will drive the mounting frame 11 to overcome the elastic force of the third elastic member 62 and switch to the abutment pushing state. During this process, the abutment part A drives the mounting frame 11 and the support plate to slide relative to the hinge seat 13, so that the push plate 61 approaches the control frame 421 and finally squeezes the control frame 421, so that the control frame 421 switches to the squeezing state, thereby limiting the angle of the snap-fit ​​assembly 41 contacting the abutment part A, so that the abutment part A can switch to the clearance angle under the push of the connecting shaft 101.

[0083] After the connecting shaft 101 passes the abutting part A, the abutting part A will not be subjected to the external force of the orientation limiting device 5. Under the action of the third elastic member 62, the mounting bracket 11 returns to the abutting fixed state, and under the action of the reset member, the abutting part A also returns to the use angle. Then the locking block 412 and the locking groove F will re-coordinate to limit the angle of the abutting part A in the use position.

[0084] Through the pressing device 6 and hinge seat 13 in this embodiment, in conjunction with the angle control device 4, limiting device 5 and engaging device 1 in the above embodiments, after the detection system completes the out-of-roundness detection, the abutment A, driven by the connecting shaft 101, drives the mounting bracket 11 to switch to the abutment pushing state, the angle control device 4, driven by the pressing of the push plate 61, switches to the releasing state, and the abutment A, driven by the connecting shaft 101, switches to the yielding angle. When the connecting shaft 101 passes the abutment A, the reset member resets the abutment A to the use angle, the third elastic member 62 switches the mounting bracket 11 to the abutment fixed state, and then the angle control device 4 switches back to the locked state. After the engaging device 1 resets to the initial state, it can prepare for the next out-of-roundness detection, realizing the continuous operation of the detection work.

[0085] For details, please refer to Figure 1 and Figure 2 The push plate 61, which is connected to the mounting bracket 11, is located on the right side of the engagement device 1. The push plate 61 can be fixedly connected to the mounting bracket 11 via a first connecting rod that is slidably connected to the hinge seat 13. The control frame 421 is also located on the right side of the engagement device 1 and is slidably connected to the hinge seat 13 via a second connecting rod.

[0086] The snap-fit ​​assembly 41 can be configured as two sets, front and back, to improve snap-fit ​​reliability and stability.

[0087] Example 7:

[0088] Reference Figures 1-10 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0089] The detection system also includes a linear drive device 7, a first track 8, and a base 9. The linear drive device 7 includes a drive unit 71 and a sliding component 72. The base 3 is supported on the base 9, and the base 9 is slidably connected to the first track 8 in the left-right direction. The drive unit 71 can drive the sliding component 72 to slide in the left-right direction. The sliding component 72 can switch between a connected state fixedly connected to the base 9 and a separated state disconnected from the base 9. When the sliding component 72 is switched to the connected state, the linear drive device 7 can drive the base 9 to slide in the left-right direction so that the engaging device 1 can switch from the end position to the initial position. When the sliding component 72 is switched to the separated state, the engaging device 1 can switch from the initial position to the end position.

[0090] In this embodiment, the linear drive device 7 can drive the base 3 to slide from the end state to the initial state, which, together with the above embodiment, realizes the full automation of the non-roundness detection work and greatly improves the detection efficiency.

[0091] When the sliding assembly 72 is in the connected state, the linear drive device 7 drives the base 9 to slide in the left and right direction, thereby causing the engagement device 1 to switch from the end position to the initial position. When the sliding assembly 72 is in the separated state, the base 9 is no longer driven by the linear drive device 7, and the engagement device 1 can be pushed and slid by the connecting shaft 101 to switch from the initial position to the end position.

[0092] By switching between the connected and disconnected states of the sliding component 72, the system can flexibly control the position of the engagement device 1 to meet the needs of the detection system.

[0093] The sliding assembly 72 includes a fixed block 721, a first telescopic drive member 722, and a pressure plate 723.
