Technical Field

[0001] This utility model belongs to the field of track inspection technology, and in particular relates to a non-destructive testing device for tracks. Background Technology

[0002] With the rapid development of the rail transit industry, the safety and reliability of the track, as the basic carrier for train operation, are of paramount importance. The track is subjected to train loads, environmental erosion and alternating stress for a long time, which can easily lead to defects such as cracks, wear and internal damage. These hidden dangers may cause serious accidents such as derailment and signal abnormalities. Therefore, efficient and accurate non-destructive testing technology has become the key to ensuring the safe operation of the track.

[0003] However, the existing non-destructive testing devices for tracks have inconveniently adjustable detector positions on both sides during use, which affects the test results and leads to discrepancies between the test results and the degree of damage, thus posing a safety hazard to the track during subsequent use. Utility Model Content

[0004] The purpose of this utility model is to provide a non-destructive testing device for tracks. By setting up a traction unit, it solves the problem that in the existing non-destructive testing devices for tracks, the positions of the detectors on both sides are not easy to adjust during use, which affects the test results and causes a discrepancy between the test results and the degree of damage, thus affecting the safety of the track in subsequent use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a non-destructive testing device for rails, comprising a fixed plate, and further comprising: a movable part mounted on the fixed plate for moving the testing device; a traction part disposed on the fixed plate; and a guide part mounted on the traction part for guiding the testing device during rail inspection; wherein, activating the traction part drives the guide part to move toward and contact the rail, and subsequently pushes the movable part to move the testing device, during which the guide part guides the testing device.

[0007] Furthermore, the movable part includes a rain shelter fixedly connected to the top of the fixed plate, a support frame fixedly connected to the top of the fixed plate, and a number of casters rotatably connected to the bottom of the fixed plate; wherein, the rain shelter protects the detection device, and the support frame is used to push the fixed plate to move the casters.

[0008] Furthermore, the traction unit includes a power component mounted on a fixed plate; and a support component mounted on the bottom of the fixed plate; wherein the power component provides power output to the traction unit, and when the power component is activated, it drives the support component to move.

[0009] Furthermore, the guide portion includes a plurality of telescopic rods disposed at the bottom of the fixed plate, and brackets are fixedly connected to the sides of the plurality of telescopic rods that are close to each other, and elastic elements are installed on the plurality of brackets; wherein, the plurality of brackets provide support for the elastic elements, and the plurality of telescopic rods are fixed to the plurality of brackets by welding.

[0010] Furthermore, the power assembly includes a hydraulic cylinder fixedly connected to the top of the fixed plate. A limiting groove is formed on the top of the fixed plate, and a slider is slidably connected to the inner wall of the limiting groove. A hinge is provided on the slider. The slider is fixedly connected to the output shaft of the hydraulic cylinder, and the limiting groove passes through the fixed plate.

[0011] Furthermore, the support assembly includes several rectangular brackets fixedly connected to the bottom of the fixed plate. Each of the rectangular brackets has two sliding rods running through it. Two traction plates are fixedly connected to the sides of the sliding rods that are close to each other. An X-ray source is fixedly connected to the sides of the two traction plates that are close to each other. A hinge block is fixedly connected to the sides of the two traction plates that are close to each other. The rectangular brackets are slidably connected to the sliding rods, and the sides of the two traction plates that are close to each other are fixedly connected to several telescopic rods. The two X-ray sources are used to detect damage inside the track.

[0012] Furthermore, the elastic element includes springs respectively sleeved on the outer walls of several telescopic rods, fixed rods passing through several brackets, and guide wheels fixedly connected to the outer walls of several fixed rods; wherein, the sides of several springs that are far apart from each other are fixedly connected to two traction plates, the sides of several springs that are close to each other are fixedly connected to several brackets, several fixed rods are rotatably connected to several brackets, and several fixed rods support several guide wheels.

[0013] Furthermore, the hinge includes a bidirectional hinge block fixedly connected to the bottom of the slider, and two hinge rods are hinged on the bidirectional hinge block; wherein, the two hinge rods are hinged to the two hinge blocks respectively on their opposite sides, and the hydraulic cylinder provides power to the bidirectional hinge block through the slider.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a traction unit, during use, the detection device is placed on the track, and then the hydraulic cylinder is activated. The hydraulic cylinder pushes the slider to slide to the right within the limit groove. At this time, the slider drives two hinge rods to move through the bidirectional hinge block. Under the action of the two hinge rods hinged to the two hinge blocks respectively, the two hinge rods rotate at the hinge point with the bidirectional hinge block. At this time, the angle between the two hinge rods decreases. The hinge rods drive the two traction plates to move closer to each other through the two hinge blocks. At this time, the two traction plates drive several corresponding slide rods to slide and move closer to each other on the corresponding rectangular brackets. With the parallel design of several slide rods, the two traction plates move smoothly. At this time, the two traction plates drive the corresponding X-ray sources to move and move closer to the track, thereby adjusting the position of the two X-ray sources. This improves the convenience and efficiency of adjustment, makes it easier to adjust to the appropriate position, improves the versatility of the detection device, avoids errors in detection results due to X-ray source position deviation, and improves the stability of detection.

[0016] 2. By setting up a guide section, during use, two traction plates drive corresponding telescopic rods to approach each other. At this time, the telescopic rods, through fixed rods on brackets, drive corresponding fixed rods to approach each other and contact the track. Subsequently, the support frame is pushed to move several universal wheels on both sides of the track through the fixed plates. When the track is in an arc state, the convex side of the track will press against the corresponding guide wheels. At this time, the guide wheels, through fixed rods, drive brackets to move. The brackets then press against the telescopic rods and springs, causing them to deform. The springs generate elastic force, and the degree of deformation varies on the convex side of the track, resulting in different pressure on the guide wheels. This causes the guide wheels to adhere to the track surface. When the track returns to a straight state, the elastic force of the springs causes the guide wheels to return to their original position, maintaining the state of contact between the guide wheels and the track surface. This ensures the stability of the relative position of the device and the track during the testing process, improves the applicability in complex track environments, guarantees the stability of test data, and improves the reliability of non-destructive testing results.

[0027] Please see Figure 1-5As shown, this utility model is a non-destructive testing device for rails, including a fixed plate 111 and a moving part 1. The moving part 1 is mounted on the fixed plate 111 and is used to push the testing device to move. The traction part 2 is activated to drive the guide part 3 to move towards and contact the rail, and then pushes the moving part 1 to move the testing device. During this process, the guide part 3 guides the testing device. The moving part 1 includes a rain shelter 112 fixedly connected to the top of the fixed plate 111. A support frame 113 is fixedly connected to the top of the fixed plate 111, and several casters 114 are rotatably connected to the bottom of the fixed plate 111. The rain shelter 112 protects the testing device, and the support frame 113 is used to push the fixed plate 111 to move the casters 114.

[0028] The traction unit 2 is mounted on the fixed plate 111 and includes a power assembly 21 mounted on the fixed plate 111 and a support assembly 22 mounted on the bottom of the fixed plate 111. The power assembly 21 provides power output to the traction unit 2. When the power assembly 21 is activated, it drives the support assembly 22 to move. The power assembly 21 includes a hydraulic cylinder 211 fixedly connected to the top of the fixed plate 111. A limit groove 212 is formed on the top of the fixed plate 111, and a slider 213 is slidably connected to the inner wall of the limit groove 212. A hinge is provided on the slider 213. The slider 213 is fixedly connected to the output shaft of the hydraulic cylinder 211. The limit groove 212 penetrates the fixed plate 111. The support assembly 22 includes several rectangular supports 221 fixedly connected to the bottom of the fixed plate 111. Each of the rectangular supports 221 has two sliding rods 222 passing through it. Two traction plates 2 are fixedly connected to the sides of the sliding rods 222 that are close to each other. 23. An X-ray source 224 is fixedly connected to one side of each of the two traction plates 223 that are close to each other, and a hinge block 225 is fixedly connected to one side of each of the two traction plates 223 that are close to each other. Several rectangular supports 221 are slidably connected to several sliding rods 222, and several telescopic rods 311 are fixedly connected to one side of each of the two traction plates 223 that are close to each other. The two X-ray sources 224 are used to detect damage inside the track. The hinge includes a bidirectional hinge block 214 fixedly connected to the bottom of the slider 213. Two hinge rods 215 are hinged on the bidirectional hinge block 214. The two hinge rods 215 are hinged to the two hinge blocks 225 on the side that are far apart from each other. The hydraulic cylinder 211 provides power to the bidirectional hinge block 214 through the slider 213.

[0029] Guide section 3, mounted on traction section 2, is used for guiding the track during inspection. Guide section 3 includes several telescopic rods 311 located at the bottom of fixed plate 111. Each telescopic rod 311 has a bracket 312 fixedly connected to one side of each rod. Elastic elements are mounted on the brackets 312. The brackets 312 provide support for the elastic elements. The telescopic rods 311 are fixed to the brackets 312 by welding. The elastic elements include springs 313 respectively sleeved on the outer walls of the telescopic rods 311. Fixed rods 314 penetrate each bracket 312. Guide wheels 315 are fixedly connected to the outer wall of the fixed rod 314; among them, the side of several springs 313 that are far apart from each other is fixedly connected to two traction plates 223, the side of several springs 313 that are close to each other is fixedly connected to several brackets 312 respectively, several fixed rods 314 are rotatably connected to several brackets 312 respectively, and several fixed rods 314 support several guide wheels 315 respectively. By setting the guide part 3, the relative position of the device and the track is kept stable during the detection process, improving the applicability in complex track environments, ensuring the stability of the detection data, and improving the reliability of non-destructive testing results.

[0030] A specific application of this embodiment is as follows: In use, the detection device is placed on the track, and then the hydraulic cylinder 211 is activated. The hydraulic cylinder 211 pushes the slider 213 to slide to the right within the limiting groove 212. At this time, the slider 213 drives the two hinge rods 215 to move through the bidirectional hinge block 214. Under the action of the two hinge rods 215 being hinged to the two hinge blocks 225 respectively, the two hinge rods 215 rotate at their hinge points with the bidirectional hinge block 214. At this time, the angle between the two hinge rods 215 decreases, and the hinge rods 215 drive the two traction plates 223 to move closer to each other through the two hinge blocks 225. At this time, the two traction plates 223 drive the corresponding number of slide rods 222 to move at the corresponding moments. The X-ray sources slide and move closer to each other on the support bracket 221. With several parallel sliding rods 222, the two traction plates 223 move smoothly. At this time, the two traction plates 223 respectively drive the corresponding X-ray sources 224 to move and move closer to the track, thereby adjusting the position of the two X-ray sources 224. The X-ray source 224 in this device is a Hamamatsu microfocus X-ray source. Its working principle is as follows: When used for non-destructive testing of the track, the Hamamatsu microfocus X-ray source emits electrons through an electron gun, which are accelerated in a high-voltage electric field to bombard the target material and generate X-rays. Its microfocus technology allows the focal point to reach the micrometer level, significantly improving imaging resolution. The X-rays penetrate the track components, and due to the absorption differences caused by material density and defects, they are converted into X-rays at the detector. Grayscale images, analyzed manually or using AI algorithms to determine grayscale distribution and shape, can identify the location, size, and nature of defects, enabling non-contact detection. Adaptable to various environments, combined with a scanning device, they can achieve rapid imaging. Digital images facilitate data archiving and trend analysis. At this point, two traction plates 223 respectively drive corresponding telescopic rods 311 closer together. These telescopic rods 311, via fixed rods 314 on brackets 312, drive corresponding fixed rods 314 closer together and into contact with the track. Subsequently, the support frame 113 is pushed, driving several casters 114 to move along both sides of the track via the fixed plates 111. When the track is in an arc shape, the convex side of the track will contact the corresponding casters 114. The guide wheels 315 are compressed. At this time, several guide wheels 315 drive several brackets 312 to move through several fixed rods 314. At this time, several brackets 312 compress several telescopic rods 311 and several springs 313, causing the telescopic rods 311 and several springs 313 to deform. At this time, several springs 313 generate elastic force. The degree of elasticity on the raised surface of the track is different, thus the compression force on several guide wheels 315 is different, causing several guide wheels 315 to fit against the surface of the track. When the track returns to a straight state, under the action of the elastic force of several springs 313, several guide wheels 315 are reset, maintaining the state of several guide wheels 315 in contact with the track surface.
