Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of track flaw detection devices, specifically a track multi-directional positioning and clamping flaw detection device. Background Technology
[0002] Track flaw detection refers to the use of flaw detection equipment to detect fatigue and welding defects at the rail head and web of rails. The detected defects include rail abrasions, etc. When the flaw detection equipment slides on the track, it records damage signals, mileage signals, and track characteristic signals. Based on the information recorded by the flaw detection equipment, inspectors can quickly determine the location and size of track damage, and also determine the track mileage affected by the damage. Using this track detection method, track damage can be detected and repaired promptly, ensuring the safe operation of trains on intact tracks and preventing unnecessary safety accidents.
[0003] For example, a mobile dual-track flaw detection and positioning device disclosed in patent announcement number CN111845844A includes a mobile base, with rollers mounted on the lower end of the mobile base. The rollers are fixed to the mobile base by a fixed seat. A flaw detection device is provided at the front end of the mobile base. The flaw detection device includes a flaw detection frame, which is fixedly connected to the mobile base by a pushing device. Flaw detection wheels are provided on the lower sides of both ends of the flaw detection frame. A flaw detector seat is mounted above the flaw detection wheels. A track guiding device is provided at the front end of the flaw detector seat. A track leading device is installed at the front end of the flaw detection wheel. The track leading device includes a track leading frame. A first flaw detector is installed on the track traction frame. Track side leading devices are installed on both sides of the flaw detector seat. The track side leading device includes a track side leading frame. A second flaw detector is installed on the track side leading frame. A rust removal device is provided at the front end of the track side leading device and is installed on the flaw detector seat. A flaw detection positioning device is installed at the rear end of the track side leading device and is installed on one side of the track side leading frame.
[0004] This mobile dual-track flaw detection and positioning device can perform efficient flaw detection on the track, improving detection efficiency, greatly increasing the track flaw detection area, effectively reducing the occurrence of subsequent accidents, improving the flaw detection accuracy, greatly reducing the flaw detection omission rate, and ensuring the safety of track operation.
[0005] As can be seen from the solutions disclosed in the existing patent documents, in dim, nighttime and tunnel environments, the flaw detector head cannot clearly and effectively photograph the condition of the track surface, resulting in a significant reduction in the flaw detection effect. In addition, when stones and debris are placed on the track surface, the flaw detector head is easily damaged and obstructed by the stones and debris when the flaw detector vehicle is moving. Therefore, it is necessary to improve the existing technology. Utility Model Content
[0006] The purpose of this invention is to provide a multi-directional positioning clamping flaw detection device for tracks, in order to solve the problems existing in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional positioning and clamping flaw detection device for rails, including a vehicle body, wherein a drive wheel is symmetrically mounted on the lower end face of the vehicle body, and a rail is rotatably connected to the lower end face of the drive wheel;

The lighting mechanisms include a support frame connected to the end of the support beam. The support frame has symmetrically arranged grooves inside. A lighting lamp is slidably inserted into the groove. A nut is threaded to the outside of the lighting lamp. A retaining ring is provided on the outside of the lighting lamp. A flaw detector head is installed inside the support frame.
[0010] The lower end face of the vehicle body is equipped with a cleaning mechanism for removing debris from the outer surface of the track.

The lighting lamp is designed to enhance the brightness of the outer side of the track, improving the clarity of the flaw detection head's monitoring. Activating the hydraulic cylinder causes the support beam and support frame to move longitudinally, allowing for easy adjustment of the flaw detection head's longitudinal position. This enables the flaw detection head to be adjusted longitudinally for clearer monitoring when it detects problems at the upper or lower ends of the track.
[0017] The design of shovel plate one and shovel plate two can remove debris from the track surface, preventing debris from colliding with or obstructing the flaw detector head and affecting normal flaw detection. Attached Figure Description

[0028] The working principle of a rail flaw detection vehicle is mainly based on ultrasonic flaw detection technology. The vehicle uses an ultrasonic probe to emit ultrasonic waves towards the rail. When these waves propagate through the rail, they encounter defects (such as cracks or core flaws), generating reflected waves. The receiver on the vehicle captures these reflected waves and determines the location and size of the defects by calculating the propagation time of the ultrasonic waves and the characteristics of the reflected waves.
[0029] Data processing
[0030] The flaw detection vehicle is equipped with an advanced data processing system that can record and analyze data received by the ultrasonic probes in real time. This data is transmitted to a control platform, where technicians can observe waveform changes on the screen to determine the internal condition of the rails. Furthermore, the vehicle also features automatic data acquisition and remote monitoring capabilities, providing technical support for railway line maintenance and management.
[0031] Work process
[0032] Preparation: The flaw detection vehicle will drive into the station to prepare for flaw detection operations. Technicians will activate and test the flaw detection vehicle to ensure that the data connection is normal.
[0033] Flaw detection operation: During the operation of the flaw detection vehicle, the flaw detection head emits ultrasonic waves and automatically collects data and performs remote monitoring.
[0034] Data Analysis: After the flaw detection is completed, technicians will organize the collected rail data, analyze and determine the damage, and form a report to submit to the maintenance unit so that the problem can be solved in a timely manner.
[0035] Report generation: The flaw detection vehicle will generate a detailed flaw detection report, including information such as the type, location, and size of the damage, providing a scientific basis for the maintenance of railway lines.
[0036] Please see Figure 1-4 The side clamping nut 23 of the support frame 2, the side clamping retaining ring 24 of the support frame 2, and one end of the flaw detector 25 is aligned with the rail 12;
[0037] With this setup, after moving the lighting lamp 22 longitudinally to the appropriate position, rotating the tightening nut 23 causes the retaining ring 24 to press against the side of the support frame 2, making it easy to adjust the lighting height of the lighting lamp 22. The design of the lighting lamp 22 can enhance the brightness of the outer side of the track 12 in order to improve the monitoring clarity of the flaw detector head 25.
[0038] Please see Figure 1-4 The support frame 2 is internally fitted with a track 12, and a lighting lamp 22 is internally fitted with the support frame 2, with one end of the lighting lamp 22 aligned with the track 12;
[0039] With this setup, the multiple flaw detectors 25 can perform flaw detection on the outer side of the track 12 over a wide area, ensuring that the train can travel safely on the intact track 12.
[0040] Please see Figure 1-4 The two sides of the track 12 are slidably connected to the first shovel plate 31, and the upper end of the track 12 is slidably connected to the second shovel plate 32.
[0041] With this setup, the hydraulic cylinder 13 is activated to drive the support beam 14 and support frame 2 to move longitudinally, which facilitates the adjustment of the longitudinal position of the flaw detector 25. When the flaw detector 25 detects problems at the upper and lower ends of the track 12, the height of the flaw detector 25 can be adjusted longitudinally for clearer monitoring.
[0042] Please see Figure 1-4 The lower end face of the vehicle body 1 is connected to the guide sleeve 16, one side of the support frame 2 is slidably connected to the fixed seat 3, the inner side of the fixed seat 3 is fixedly connected to the second shovel plate 32, and one side of the support frame 2 is slidably connected to the first shovel plate 31.
[0043] With this setup, the design of the telescopic rod 15 and the guide sleeve 16 can guide the longitudinal movement of the support beam 14 and the support frame 2, preventing the support frame 2 from deflecting and affecting the flaw detection head 25's flaw detection of the outer surface of the track 12. The design of the first shovel plate 31 and the second shovel plate 32 can remove debris from the surface of the track 12, preventing debris from colliding with and obstructing the flaw detection head 25, thus affecting normal flaw detection.
[0044] The working principle of this embodiment is as follows:
[0045] The multi-directional positioning clamping flaw detection device for the track can move the lighting lamp 22 longitudinally to a suitable position, and then rotate the tightening nut 23 to drive the retaining ring 24 to press the side of the support frame 2. This allows for easy adjustment of the lighting height of the lighting lamp 22. The design of the lighting lamp 22 can brighten the outer side of the track 12 to improve the monitoring clarity of the flaw detection head 25. The design of the flaw detection head 25 in multiple positions can perform flaw detection inspection on the outer side of the track 12 over a wide area to ensure that the train can run safely on the intact track 12.
[0046] By activating the hydraulic cylinder 13, the support beam 14 and support frame 2 are moved longitudinally, which facilitates the adjustment of the longitudinal position of the flaw detector 25. When the flaw detector 25 detects a problem at the upper or lower end of the track 12, the height of the flaw detector 25 can be adjusted longitudinally for clearer monitoring.
[0047] The design of the telescopic rod 15 and the guide sleeve 16 can guide the longitudinal movement of the support beam 14 and the support frame 2, and prevent the support frame 2 from deflecting to affect the flaw detection head 25 to detect flaws on the outer surface of the track 12. The design of the shovel plate 1 31 and the shovel plate 2 32 can remove debris from the surface of the track 12, and prevent debris from colliding with and obstructing the flaw detection head 25, thus affecting normal flaw detection.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
