Description

Technical Field

[0001] The present invention relates to the technical field of out-of-roundness detection, and particularly to a wear degree detection system for a wheel set assembly and a train inspection station. Background Art

[0002] The inspection of the wheel sets of rail trains is an important measure to ensure the safe, reliable, economic and compliant operation of trains. To ensure the inspection efficiency and accuracy, inspection devices are usually used to inspect the wheel sets. However, since the train wheels are located at the bottom of the train and the train wheels are in contact with the rails, it causes obstacles to the inspection and cannot guarantee the inspection accuracy.

[0003] Patent CN219523906U discloses a wheel set wheel flange and tread wear detection device. When in use, first install the mounting piece outside the bearing and in the middle of the tread, then connect the first sliding piece and the sensor to the mounting piece, and adjust the sensor in place through the expansion or rotation of the first connecting plate and the second connecting plate. The first sensor faces the tread of the wheel set, and the second sensor faces the wheel flange of the wheel set. Through the sliding of the second sliding piece in the circular chute, the first sensor rotates to detect the tread of the wheel set for one week, and the second sensor rotates to detect the wheel flange of the wheel set for one week. Once installed, the tread and wheel flange of the wheel set can be rotated and detected for one week.

[0004] It can be seen that this technical solution is a detection method that directly establishes a connection with the wheel set. The detection process includes the installation and disassembly processes of the detection device, and these two processes will consume a lot of time, resulting in low detection efficiency. Summary of the Invention

[0039] For better explaining the present invention and facilitating understanding, the following combines the attached Figures 1 - 10, through specific embodiments, the present invention will be described in detail. Among them, the orientation nouns such as "upper" and "lower" mentioned herein are referenced with the orientation of Figure 1 as a reference.

[0040] Embodiment 1:

[0041] Referring to Figures 1 - 10 , an embodiment of the present invention provides a wheel pair component wear degree detection system. The wheel pair component 100 includes a connecting shaft 101 extending in the front-rear direction, and wheel pairs 102 fixedly connected to both ends of the connecting shaft 101. The system includes an engaging device 1, a measuring module 2, and a base 3; both the engaging device 1 and the measuring module 2 are supported on the base 3, and a vertically extending abutting portion A is formed on the engaging device 1; the engaging device 1 and the base 3 can slide and switch between an initial position and a final position in the left-right direction; when the wheel pair component 100 rolls in the left-right direction, the connecting shaft 101 can push the abutting portion A, thereby driving the engaging device 1 to slide and switch from the initial position to the final position, so that the measuring module 2 can detect the out-of-roundness of the wheel pair 102 when the wheel pair 102 rotates.

[0042] In this embodiment, the wheel pairs 102 are fixedly connected to both ends of the connecting shaft 101, which are the parts actually in contact with the track and bearing wear. The base 3 serves as the support structure of 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 abutting portion A.

[0043] The specific detection process is as follows: The engaging device 1 is in the initial position, and the measuring module 2 is ready. When the wheel pair component 100 rolls in the left-right direction, the connecting shaft 101 will contact the abutting portion A of the engaging device 1, and the driving force of the connecting shaft 101 causes the engaging device 1 to start sliding from the initial position. The engaging device 1 gradually slides to the final position under the push of the connecting shaft 101, so that the measuring module 2 can run synchronously with the wheel pair component 100 in the left-right direction. In this way, the measuring module 2 can detect the out-of-roundness of the wheel pair 102 in real time. By limiting the displacement amount of the wheel pair component 100 from the initial position to the final position to be greater than the circumference of the wheel pair 102, the measuring module 2 can complete the out-of-roundness detection work of the wheel pair 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 abutting portion A, thereby realizing the out-of-roundness detection of the wheel pair 102, the entire process does not include the connection process between the device and the wheel pair component 100. Therefore, the out-of-roundness detection process of the wheel pair 102 is greatly simplified, and the detection efficiency of the wheel pair 102 is improved.

[0045] Specifically, the measuring module 2 is set as a laser sensor, which emits a light signal to the wheel pair 102 to detect the wear degree of the wheel pair 102.

[0046] Embodiment 2:

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

[0048] The abutment portion A is hinged on the base 3 along the front-to-back direction so that the abutment portion A can swing and switch between the use angle and the yield angle; the detection system also includes an angle control device 4, which can switch between a locked state that limits the swing of the abutment portion A relative to the base 3 and a loosened state that allows the abutment portion A to swing relative to the base 3; when the angle control device 4 switches to the locked state, the abutment portion A maintains the use angle, and the connecting shaft 101 can push the abutment portion A and thereby drive the engagement device 1 to slide and switch from the initial position to the end position, so that the measuring module 2 detects the out-of-roundness of the wheelset 102 when the wheelset 102 rotates; when the abutment portion A is pushed by the connecting shaft 101 to make the engagement device 1 slide and switch to the end position, the angle control device 4 can switch to a loosened state, so that the abutment portion A can switch to the yield angle under the push of the connecting shaft 101, thereby allowing the wheelset assembly 100 to continue rolling and pass over the abutment portion A.

[0049] In this embodiment, the abutment portion A is hinged on the base 3 along the front-to-back direction. This design allows the abutment portion A to swing freely between the use angle and the yield angle. The use angle is the fixed angle when the abutment portion A is in normal contact with the wheelset 102 and is measuring. At this time, the abutment portion A can drive the base 3 and the measuring module 2 on the base 3 to run synchronously under the push of the connecting shaft 101 to complete the out-of-roundness detection of the wheelset 102; the yield angle is the angle at which the abutment portion A is swung open to allow the wheelset assembly 100 to continue rolling without hindrance. At this time, the corresponding detection work is completed. By switching the abutment portion A to the yield angle, the wheelset assembly 100 can continue to roll continuously to avoid affecting the normal operation of the wheelset assembly 100, thereby further improving the detection efficiency.

[0050] The angle control device 4 has two working modes: a locked state and a released state. In the locked state, the abutment portion A is fixed at the use angle and cannot swing freely, ensuring the stability and accuracy of the measurement process. In the released state, the abutment portion A can swing freely to the yield angle, allowing the wheelset 102 to roll smoothly. When the angle control device 4 is switched to the locked state, the abutment portion A maintains the use angle. At this time, the connecting shaft 101 pushes the abutment portion A, thereby driving the coupling 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 when the wheelset 102 rotates.

[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 loose state. In the loose state, the abutment portion A swings to the yield angle under the push of the connecting shaft 101, allowing the wheelset 102 to continue rolling and pass over the abutment portion A.

[0052] The hinged setting of the abutment portion A in this embodiment, in conjunction with the angle control device 4, enables the monitoring system to continue rolling without affecting the wheelset assembly 100 after the detection is completed, thereby improving the flexibility of use.

[0053] Embodiment 3:

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

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

[0056] In this embodiment, the engaging device 1 comprises a mounting frame 11 and a roller set 12. The roller set 12 is rotatably connected to the mounting frame 11 in the front-to-back direction to form an abutment portion A. The mounting frame 11 is hinged to the base 3 in the front-to-back direction, so that the engaging device 1 can swing between a use angle and a yield angle.

[0057] The roller group 12 includes at least one roller, and the roller can rotate freely. When the abutment portion A is at the use angle and the connecting shaft 101 pushes the abutment portion 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 thrust transmission, and also enabling the connecting shaft 101 to maintain rolling contact with the abutment portion A, reducing the friction loss of the connecting shaft 101 and improving the smoothness of the detection process.

[0058] The coupling device 1 also includes a reset member, such as a torsion spring. When the coupling device 1 needs to switch from the yielding angle back to the use angle, the reset member releases the stored force and provides a reset force, so that the coupling device 1 can quickly and accurately return to the use angle for the next detection, which is beneficial to improving the detection efficiency.

[0059] Specifically, the coupling device 1 also includes a support roller rotatably connected to the mounting frame 11. When the connecting shaft 101 cooperates with the roller, the support roller contacts the connecting shaft 101 at the bottom, which is beneficial to improve the stability of the coupling device 1 when switching positions.

[0060] Embodiment 4:

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

[0062] The detection system further comprises a limiting device 5. When the engaging device 1 slides from the initial position to the final position, the limiting device 5 can limit the engaging device 1 from sliding further in the direction away from the initial position.

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

[0064] When the engaging device 1 slides and switches from the initial position to the final position, the limiting device 5 can function to prevent the engaging device 1 from continuing to slide in the direction away from the initial position, so that the wheelset assembly 100 can continue to roll. After the angle control device 4 is switched to the released state, the abutment portion A can be switched to the yielding angle under the push of the connecting shaft 101, allowing the wheelset assembly 100 to continue to roll and pass over the abutment portion A, thereby avoiding affecting the continuous operation of the wheelset assembly 100.

[0065] Specifically, the limiting device 5 can be a mechanical stopper, 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, the other end of the spring is connected to the baffle, and the buffer pad is connected to the side wall of the baffle facing the base 3 to withstand the impact from the base 3.

[0066] The limiting device 5 in this embodiment cooperates with the abutment part A and the angle control device 4. After the coupling device 1 slides to the end position and the angle control device 4 is switched to the released state, the connecting shaft 101 pushes the abutment part A to switch the abutment part A to the yielding angle, thereby ensuring that the wheelset assembly 100 can continue to operate without interference.

[0067] Embodiment 5:

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

[0069] The angle control device 4 includes a clamping assembly 41 and a control assembly 42. The clamping assembly 41 includes a support 411, a clamping block 412 and a clamping seat 413. The support 411 is fixedly connected to the base 3. The clamping block 412 is slidably installed on the support 411 along the front-back direction. The clamping seat 413 is fixedly connected to the mounting frame 11, and a clamping slot F is provided on the clamping seat 413. The clamping block 412 can switch between a limiting state matched with the clamping slot F and a release state disengaged from the clamping slot F. The clamping assembly 41 also includes a first elastic member 414. The first elastic member 414 accumulates force when the clamping block 412 switches from the limiting state to the release state, so as to provide the clamping block 412 with a reset force to switch from the release state to the limiting state. The control assembly 42 includes a control frame 421, the control frame 421 can slide along the left and right directions relative to the support 411, and a first pushing portion B that can squeeze the block 412 is formed on the control frame 421; a second pushing portion C is formed on the block 412, and the control frame 421 can drive the first pushing portion B to switch between an extrusion state of pushing the second pushing portion C and a separation state away from the second pushing portion C; when the first pushing portion B continues to push the second pushing portion C, the block 412 can switch from a limited state to a released state; the second pushing portion C is set as an inclined surface; the control component 42 also includes a second elastic member 422, and the second elastic member 422 accumulates force when the control frame 421 switches from a separation state to an extrusion state, so as to provide the control frame 421 with a reset force to switch from an extrusion state to a separation state.

[0070] In this embodiment, the angle control device 4 includes a clamping assembly 41 and a control assembly 42 for controlling the locking and releasing states of the engagement device 1 .

[0071] The block 412 can switch between a limited state in cooperation with the slot F and a released state in which it is disengaged from the slot F. In the limited state, the block 412 is inserted into the slot F to fix the engagement device 1 at the use angle. In the released state, the block 412 is disengaged from the slot F, and the engagement device 1 can swing freely to the yield angle. The first elastic member 414 accumulates force when the block 412 switches from the limited state to the released state, providing the block 412 with a reset force to switch from the released state to the limited state.

[0072] The control frame 421 can drive the first push part B to switch between a squeeze state of squeezing the second push part C and a separation state away from the second push part C. When the first push part B continues to push the second push part C, the block 412 can switch from the limit state to the release state. The second elastic member 422 accumulates force when the control frame 421 switches from the separation state to the squeeze state, providing the control frame 421 with a reset force to switch from the squeeze state to the separation state.

[0073] When the joint device 1 needs to be at the working angle, the control frame 421 is in the separated state, and the first elastic member 414 pushes the latch 412 into the slot F to achieve the limiting state, fixing the joint device 1 at the working angle for measurement preparation.

[0074] When the joint device 1 needs to be switched to the yielding angle, an external force pushes the control frame 421 to the squeezing state. At this time, the first pushing portion B squeezes the second pushing portion C, causing the latch 412 to disengage from the slot F to achieve the release state. The abutting portion A of the joint device 1 swings to the yielding angle under the push of the connecting shaft 101.

[0075] After the wheel set assembly 100 passes over the abutting portion A, under the action of the reset member, the abutting portion A will reset to the working angle. And when the reset force of the reset member can overcome the external force applied to the control frame 421, the latching assembly 41 can be switched to the limiting state, thereby being able to limit the abutting portion A at the working angle.

[0076] Specifically, the second pushing portion C is an inclined surface facing the first pushing portion B. Not only can the first abutting portion A push the inclined surface to compress the second elastic member 422 by the latch 412, but also when the abutting portion A swings and switches from the yielding angle to the working angle, the card seat fixed in the relative position with the abutting portion A can also push the inclined surface to compress the second elastic member 422 by the latch 412, thereby enabling the latch 412 to re - establish the cooperation relationship with the slot F.

[0077] More specifically, the side wall of the card seat 413 where the slot F is opened is the side wall of the card seat 413 facing the latch 412 when the abutting device is switched to the working angle, facilitating the cooperation between the slot F and the latch 412. The edge of the card seat 413 forms a third pushing portion D that can push the second pushing portion C.

[0078] Embodiment 6:

[0079] Refer to Figures 1 - 10 In addition to having all the technical solutions of the above - mentioned embodiments, the embodiments of the present invention further have the following technical solutions:

[0080] The detection system also includes a squeezing device 6 and an articulated seat 13, wherein the squeezing device 6 includes a push plate 61 and a third elastic member 62; the mounting frame 11 is hinged to the base 3 through the articulated seat 13, and the mounting frame 11 is slidably connected to the articulated seat 13 in the left-right direction so that the mounting frame 11 can switch between the abutting pushing state and the abutting fixed state; the push plate 61 is fixedly connected to the mounting frame 11, and when the mounting frame 11 is driven by the abutting portion A to switch from the abutting fixed state to the abutting pushing state, the push plate 61 can squeeze the control frame 421 so that the control frame 421 switches from the separated state to the squeezed state; the third elastic member 62 can store force when the mounting frame 11 switches from the abutment fixed state to the abutment push state, so as to provide the mounting frame 11 with a reset force to switch from the abutment push state to the abutment fixed state; when the mounting frame 11 is in the abutment fixed state, the connecting shaft 101 can push the abutment part A to make the coupling device 1 slide; when the limiting device 5 limits the movement of the coupling device 1 and the connecting shaft 101 continues to push the abutment part A, the mounting frame 11 switches from the abutment fixed state to the abutment push state.

[0081] In this embodiment, under normal circumstances, that is, when the coupling device 1 is not restricted from moving, the connecting shaft 101 pushes the abutment portion A, and the abutment portion A and the mounting frame 11 are fixed. When the force cannot overcome the elastic force of the third elastic member 62, the mounting frame 11 maintains an abutment fixed state, and at the same time, the mounting frame 11 drives the coupling device 1 to slide. During this process, the measuring module 2 can detect the out-of-roundness of the wheelset 102.

[0082] When the coupling device 1 is restricted from moving, the connecting shaft 101 continues to push the abutment part A, and 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, and then the clamping assembly 41 contacts the angle limit of the abutment part A, so that the abutment part A can switch to the yielding angle under the push of the connecting shaft 101.

[0083] After the connecting shaft 101 passes over the abutment portion A, the abutment portion A will not be subjected to external force toward the limiting device 5. Under the action of the third elastic member 62, the mounting frame 11 is reset to the abutment fixed state, and under the action of the reset member, the abutment portion A is also reset to the use angle, and then the block 412 and the slot F will re-match to limit the angle of the abutment portion A in the use position.

[0084] Through the squeezing device 6 and the hinge seat 13 in this embodiment, in conjunction with the angle control device 4, the limiting device 5 and the coupling device 1 in the above embodiment, after the detection of the out-of-roundness is completed, the abutting portion A drives the mounting frame 11 to switch to the abutting pushing state under the push of the connecting shaft 101, the angle control device 4 switches to the loose state under the squeeze of the push plate 61, and the abutting portion A switches to the yielding angle under the push of the connecting shaft 101. After the connecting shaft 101 passes over the abutting portion A, the reset member resets the abutting portion A to the use angle, and the third elastic member 62 switches the mounting frame 11 to the abutting fixed state, thereby causing the angle control device 4 to switch back to the locked state, and then after the coupling device 1 is reset to the initial state, it can meet the next out-of-roundness detection work, thereby realizing the continuous progress of the detection work.

[0085] Specifically, refer to Figure 1 and Figure 2 The push plate 61 connected to the mounting frame 11 is located on the right side of the coupling device 1. The push plate 61 can be fixedly connected to the mounting frame 11 through 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 coupling device 1 and is slidably connected to the hinge seat 13 through a second connecting rod.

[0086] The clamping assembly 41 can be arranged into two groups, front and rear, to improve the clamping reliability and stability.

[0087] Embodiment 7:

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

[0089] The detection system also includes a linear drive device 7, a first rail 8 and a base 9. The linear drive device 7 includes a drive part 71 and a sliding assembly 72. The base 3 is supported on the base 9, and the base 9 is connected to the first rail 8 in a sliding manner along the left and right directions. The drive part 71 can drive the sliding assembly 72 to slide in the left and right directions. The sliding assembly 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 assembly 72 switches to the connected state, the linear drive device 7 can drive the base 9 to slide in the left and right directions, so that the coupling device 1 can switch from the end position to the initial position. When the sliding assembly 72 switches to the separated state, the coupling device 1 can switch from the initial position to the end position.

[0090] In this embodiment, under the action of the linear drive device 7, the base 3 can be driven to slide from the final state to the initial state, and the above embodiment is combined to achieve full automation of the out-of-roundness detection work, greatly improving the detection efficiency.

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