Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, specifically a railway track wear monitoring device. Background Technology

[0002] As a crucial component of railway transportation, steel rails bear the weight of trains and the impact forces they experience during operation. Over time, the rail surface gradually wears down due to friction. Worn rails can cause trains to experience bumps and jolts, affecting their smooth operation and potentially leading to safety accidents. Therefore, wear monitoring devices are needed to monitor rail wear. Once wear exceeds safety standards, timely repairs or replacements can be carried out, ensuring the safe operation of railways.

[0003] In related technologies, track wear is detected using ultrasonic flaw detectors. The probe is placed on the workpiece to be tested; it emits ultrasonic waves and receives the reflected signals. The internal processing system of the instrument displays the internal defects of the workpiece. However, when inspecting tracks, the device is fixedly installed beside the track, and the probe cannot be automatically moved or adjusted. Inspectors must manually adjust the probe's position and angle, which is time-consuming and reduces inspection efficiency. Furthermore, the operator's skill level and experience can affect the probe's accurate position during manual adjustment, introducing human error. Therefore, those skilled in the art have provided a railway track wear monitoring device to address the problems mentioned in the background technology. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A railway track wear monitoring device, comprising:

[0026] Mounting plate 1, mounting plate 1 has several mounting threaded holes 2, mounting plate 1 has a placement box 3, the placement box 3 has a protective glass 4, the placement box 3 has an ultrasonic flaw detector 5, the ultrasonic flaw detector 5 has a connecting line 6 connected to one side, and the connecting line 6 passes through the placement box 3 and has a probe 7 connected to one end.

[0027] Furthermore, a clamping spring 14 is installed on one side of the inner cavity of the placement box 3, and a clamping plate 15 is connected to the other end of the clamping spring 14. A box door 16 is installed on the end of the placement box 3 away from the clamping plate 15. A first rubber layer 17 is provided on one side of both the box door 16 and the clamping plate 15. The first rubber layer 17 is in contact with the ultrasonic flaw detector 5.

[0028] During installation of mounting plate 1, bolts are used to connect to the mounting threaded holes 2 to fix mounting plate 1 to one side of the track. Then, the door of the placement box 3 is opened, and the ultrasonic flaw detector 5 is placed into the inner cavity of the placement box 3. The probe 7 and the connecting wire 6 pass through the placement box 3. Then, the box door 16 is closed. After the box door 16 is closed, the clamping spring 14 releases its elastic potential energy and pushes the clamping plate 15. The first rubber layer 17 on one side of the clamping plate 15 contacts the ultrasonic flaw detector 5, which can clamp the ultrasonic flaw detector 5 and reduce the movement and collision of the ultrasonic flaw detector 5 in the placement box 3. The placement box 3 can protect the ultrasonic flaw detector 5 and reduce the ultrasonic flaw detector 5 from direct exposure to the outdoors. The protective glass 4 can protect the ultrasonic flaw detector 5 without affecting the observation of the ultrasonic flaw detector 5's detection data.

[0029] A support plate 8 is mounted on the mounting plate 1. A first connecting plate 9 is connected to the support plate 8 via a moving component. The moving component includes a servo motor 18, a threaded rod 19, and a moving block 20. The support plate 8 has a moving groove 21 for the threaded rod 19 to rotate and connect. The moving block 20 is threadedly connected to the threaded rod 19. The servo motor 18 is mounted on one end of the support plate 8, and the output end of the servo motor 18 is connected to the extension end of the threaded rod 19 that passes through the moving groove 21. The first connecting plate 9 is connected to the moving block 20.

[0030] When adjusting the distance between the probe 7 and the track, the servo motor 18 drives the moving block 20 to move in the moving groove 21 through the threaded rod 19, thereby moving the probe 7. No manual adjustment is required, which can improve the efficiency of the detection work. When the probe 7 detects track wear, it can promptly remind the operator to inspect and repair the wear.

[0031] An electric push rod 10 is installed on the first connecting plate 9. The electric push rod 10 can drive the probe 7 to adjust its height according to the track height. The output end of the electric push rod 10 is connected to the first clamping block 11 through a rotating assembly. The rotating assembly includes a drive motor 22, a first connecting block 23 and a second connecting block 24. The first connecting block 23 and the second connecting block 24 are connected by a rotating rod 25. The drive motor 22 is installed on one side of the first connecting block 23, and the output end of the drive motor 22 is connected to the extension end of the rotating rod 25 through the first connecting block 23. The first connecting block 23 and the second connecting block 24 are respectively connected to the output end of the electric push rod 10 and the first clamping block 11.

[0032] When adjusting the detection angle of probe 7, drive motor 22 drives second connecting block 24 to rotate within first connecting block 23 via rotating rod 25, which can drive probe 7 to rotate, thereby adjusting different angles for detection.

[0033] One end of the first clamping block 11 is rotatably connected to the second clamping block 12, and the other end of the second clamping block 12 is connected to the first clamping block 11 via a locking assembly. The locking assembly includes a second connecting plate 26 and a third connecting plate 27.

The second connecting plate 26 is provided with a through hole 30 for the triangular locking block 29 to pass through. A distance measuring sensor 13 is installed on one side of the first clamping block 11.

[0034] Furthermore, both the first clamping block 11 and the second clamping block 12 are provided with a second rubber layer 31, which is in contact with the probe 7.

[0035] When the probe 7 is fixed, it will contact and connect with the second rubber layer 31 on the first clamping block 11. Then, the second clamping block 12 is rotated, and the inclined surface of the triangular engaging block 29 contacts the through hole 30. The second clamping block 12 is squeezed, the engaging plate 28 is deformed, the triangular engaging block 29 passes through the through hole 30, and the triangular engaging block 29 contacts and connects with the second connecting plate 26. The engaging block is engaged in the through hole 30, so that the second connecting plate 26 and the third connecting plate 27 can be engaged and connected, thereby engaging and connecting the other end of the second clamping block 12 and the first clamping block 11. The second rubber layer 31 on the first clamping block 11 and the second clamping block 12 contacts and connects with the probe 7, so that the probe 7 can be clamped and fixed.

[0036] When disassembling the probe 7, push the triangular locking block 29 and pull the second clamping block 12 at the same time to remove the triangular locking block 29 from the through hole 30.

[0037] The ranging sensor 13 can detect the distance between the probe 7 and the track. The moving component drives the probe 7 to move and adjust, which has high adjustment accuracy, thereby improving the detection accuracy.

[0038] It should be noted that the specific models and specifications of the ranging sensor 13 and the ultrasonic flaw detector 5 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
