Description

Technical Field

[0001] This utility model relates to the technical field of crack monitoring devices, and in particular to a microcrack monitoring device for the root end of a rail tip. Background Technology

[0002] In the field of railway track maintenance, the safety inspection of switch rails is crucial, and magnetic particle testing is a commonly used and effective method for detecting internal or surface cracks in switch rails. However, existing magnetic particle testing procedures have many drawbacks, which seriously affect inspection efficiency and maintenance effectiveness.

[0003] Current methods for monitoring magnetic particle testing heavily rely on manual operation by personnel. The testing process is not only time-consuming and labor-intensive, but also requires a high level of experience and operational skills from the operators. It involves manually extracting the magnetic suspension and spraying it onto the switch rail. After starting the magnetic detector, the test data must be manually observed, recorded, and analyzed. The entire process is cumbersome and extremely inefficient.

[0004] After the inspection is completed, the cleaning work also poses a challenge for maintenance personnel. The residual magnetic powder needs to be cleaned manually by the operators, usually with the help of simple tools such as brushes and rags, wiping the surface of the switch rail one by one. This not only consumes a lot of manpower, greatly reducing the efficiency of the inspection, but also makes it difficult to completely remove the magnetic powder. The residual magnetic powder may affect the normal use of the switch rail, leading to switch rail corrosion or other malfunctions, increasing the potential risks of railway maintenance.

The output end of the pump body is connected to the lifting pipe through a first flexible hose. A nozzle is provided at the bottom of the lifting pipe. A magnetic detector is provided at the bottom of the lifting rod.

[0008] As a preferred embodiment of this utility model, the bottom of the installation platform is provided with a slanted mounting plate, the slanted mounting plate is located behind the nozzle, a high-definition camera is provided on the slanted mounting plate, and a lighting lamp is provided on the side of the high-definition camera.

[0009] As a preferred embodiment of this utility model, a first movable groove is provided on one side of the top of the installation platform, and a second movable groove communicating with the first movable groove is provided on the side of the installation platform.

[0010] As a preferred embodiment of this utility model, the cleaning component includes a cleaning fluid storage tank disposed on the top of the installation platform. A second pump body is disposed on the side of the cleaning fluid storage tank. The input end of the second pump body is connected to the cleaning fluid storage tank, and the output end of the second pump body is connected to a delivery pipe through a second flexible hose. The delivery pipe is disposed in a moving trough. A diverter is disposed at the bottom of the delivery pipe, and a scraper is disposed at the front end of the diverter. Several magnetic blocks are disposed at the top of the scraper. A fixing screw is disposed on the outer wall of the delivery pipe. The fixing screw is located in the moving trough and is fixed in the moving trough by a nut.

[0011] As a preferred embodiment of this utility model, a push-pull handle is provided on one side of the top of the installation platform, and a main control screen is provided on the top of the push-pull handle. The main control screen is electrically connected to pump body one, pump body two, high-definition camera, lighting lamp, magnetic detector and telescopic cylinder.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model reduces the interference of human factors on the test results through automated operation. It avoids the fact that in traditional manual testing, the experience and fatigue of the testers will affect the accuracy of the test. The automated magnetic particle monitoring component of this device can accurately deploy the magnetic detector and nozzle above the root end of the switch rail, and stably complete the magnetic suspension spraying and testing work according to the preset program. The high-definition camera, combined with the automated shooting process, can also stably obtain clear images of the switch rail, providing a reliable basis for the test and ensuring the accuracy and consistency of the test results.

[0014] 2. This utility model, through the support legs and rollers at the four corners of the device's bottom, allows operators to easily push the entire device to the top of the switch rail. The movement is labor-saving and flexible, facilitating quick positioning of the detection location and greatly saving manpower and time costs. At the same time, the main control screen centrally controls components such as pump body one, pump body two, high-definition camera, lighting, magnetic detector, and telescopic cylinder. Operators only need to complete various complex operations on one operating interface, eliminating the need for dispersed operations in multiple locations, thus improving work efficiency and operational accuracy.

[0015] 3. In the magnetic particle monitoring component of this utility model, through the coordinated action of the telescopic cylinder, the double-headed fixing component, the lifting rod and the lifting pipe, the magnetic detector and the nozzle can be accurately deployed above the root end of the switch rail, ensuring the accuracy of the detection position. The high-definition camera, combined with the lighting, can clearly capture the surface condition of the switch rail after the magnetic suspension liquid is sprayed during the detection process, providing clear and accurate image evidence for judging whether there are cracks inside or on the surface of the switch rail, avoiding misjudgment or omission due to unclear detection, and improving the reliability of detection.

[0016] 4. In the cleaning component of this utility model, several magnetic blocks set on the top of the scraper can effectively adsorb the magnetic powder remaining on the switch rail after detection. In conjunction with the pump body two, the cleaning liquid is drawn from the cleaning liquid storage tank and sprayed out through the diversion channel. As the operator pushes the installation platform forward, the magnetic powder and other impurities on the switch rail can be thoroughly washed away, ensuring the cleanliness of the switch rail surface and providing good conditions for subsequent normal use and maintenance.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figures 1-6 As shown, the present invention proposes a microcrack monitoring device for the root end of a switch rail, which is mainly composed of an installation platform 1. The four corners of the bottom of the installation platform 1 are respectively provided with support legs 10, and the bottom of the support legs 10 is equipped with rollers 11 to facilitate the movement of the device. A magnetic particle monitoring component 2 is arranged on one side of the installation platform 1, and a cleaning component 3 is arranged on the other side.

[0026] On one side of the top of the installation platform 1, there is a pair of sliding sleeves 16, and an installation groove 18 is opened between the two sliding sleeves 16. The magnetic particle monitoring component 2 includes a lifting rod 21 and a lifting pipe 22 respectively placed in the two sliding sleeves 16. A telescopic cylinder 25 is installed in the installation groove 18. The top of the telescopic rod of the telescopic cylinder 25 is connected to a double-headed fixing member 26. The lifting rod 21 and the lifting pipe 22 are respectively fixed to both ends of the double-headed fixing member 26. A pump body 20 is provided on the top of the installation platform 1. A magnetic suspension liquid storage tank 28 is located on one side of the pump body 20. The input end of the pump body 20 is connected to the magnetic suspension liquid storage tank 28, and the output end is connected to the lifting pipe 22 through a first flexible hose 27. A nozzle 23 is installed at the bottom of the lifting pipe 22, and a magnetic detector 24 is installed at the bottom of the lifting rod 21.

[0027] At the bottom of the mounting platform 1, behind the nozzle 23, there is a slanted mounting plate 13. A high-definition camera 14 is installed on the slanted mounting plate 13, and a lighting lamp 15 is provided on the side to capture the switch rail detection area and assist in the detection.

[0028] The top side of the mounting platform 1 has a movable groove 4, and the side has a movable groove 5 that communicates with the movable groove 4. These two grooves are used to install the relevant parts of the cleaning component 3.

[0029] Regarding the cleaning component 3, the top of the installation platform 1 is equipped with a cleaning liquid storage tank 30, and the side is equipped with a second pump body 31. The input end of the second pump body 31 is connected to the cleaning liquid storage tank 30, and the output end is connected to the delivery pipe 32 through the second hose 34. The delivery pipe 32 is installed in the first moving trough 4, and the bottom is connected to the diverter 33. The front end of the diverter 33 is equipped with a scraper 35. Several magnetic blocks 36 are fixed on the top of the scraper 35. The outer wall of the delivery pipe 32 is equipped with a fixing screw 37. The screw is located in the second moving trough 5. The delivery pipe 32 is fixed in the second moving trough 5 by a nut 38. The height of the delivery pipe 32 and the scraper 35 can be adjusted by adjusting the nut 38.

[0030] In terms of ease of operation, a push-pull handle 12 is provided on one side of the top of the installation platform 1, which makes it easy for operators to push the device. The main control screen 17 is installed on the top of the push-pull handle 12. The main control screen 17 is electrically connected to the pump body 1 20, pump body 2 31, high-definition camera 14, lighting lamp 15, magnetic detector 24 and telescopic cylinder 25. Operators can complete various operations on the main control screen 17 to achieve automated detection and cleaning.

[0031] First, the operator must prepare by checking the device for any damage and ensuring all connections are secure. Once everything is in order, the device should be smoothly pushed onto the switch rail. After reaching the designated position, the operator should stand in a convenient position, focusing on the high-definition camera 14 connected to the device. Using the main control screen 17 connected to the camera 14, the operator should carefully observe the relative position of the device and the switch rail to ensure the entire device is in the ideal starting position. Then, the position of the nozzle 23 should be located on the main control screen 17. When the nozzle 23 is directly above the base of the switch rail, the corresponding control button on the main control screen 17 should be pressed to activate the telescopic cylinder 25. The telescopic cylinder 25 will then receive the command. Then, the operation begins. The internal telescopic rod slowly retracts. Since the telescopic rod is tightly connected to the double-headed fixing part 26, the double-headed fixing part 26 also moves downward as the telescopic rod descends. Next, the double-headed fixing part 26 is firmly connected to the lifting rod 21 and the lifting pipe 22. Therefore, during the descent of the double-headed fixing part 26, it will drive the lifting rod 21 and the lifting pipe 22 to move downward together. During the entire descent process, the operator must pay close attention to the operation of each component to ensure smooth operation without jamming or abnormality. Until the magnetic detector 24 gently contacts the switch rail, the operator shuts off the telescopic cylinder 25 to stop the movement of each component. At this point, the magnetic detector 24 has been successfully deployed.

[0032] Immediately, the main control screen 17 was operated again to start pump body 20. After pump body 20 started, it began to perform its suction function, drawing the black water magnetic suspension from the magnetic suspension tank 28 through the pipeline. The black water magnetic suspension flowed in the pipeline and was finally sprayed evenly from the nozzle 23 in a mist onto the root end of the switch rail. After the magnetic suspension was sprayed, the magnetic detector 24 was started, and the high-definition camera 14 also started working to take pictures of the root end of the switch rail that had been sprayed with magnetic suspension. After the pictures were taken, professional technicians carefully observed the pictures and, based on relevant testing standards and experience, judged whether there were any crack marks in the pictures, thereby inferring whether there were cracks inside or on the surface of the switch rail.

[0033] After monitoring is completed, in order to carry out subsequent cleaning work, the magnetic particle monitoring component 2 needs to be reset first. Then, operate the control button on the main control screen 17 for the telescopic cylinder 25 to start the telescopic cylinder 25, so that the telescopic cylinder 25 works in reverse, causing the telescopic rod to extend and drive the entire magnetic particle monitoring component 2 (including the magnetic detector 24, nozzle 23 and other related components) to rise and return to the initial high position. After that, the operator uses a suitable tool (such as a wrench) to loosen the nut 38 connecting the delivery pipe 32 to the fixed structure. After the nut 38 is loosened, the delivery pipe 32 begins to move downward in the moving groove 4 under the action of gravity or a slight external force until the scraper 35 just contacts the upper surface of the switch rail. At this time, the operator stops operating the delivery pipe 32. Next, the main control panel 17 starts pump body 31. Pump body 31 begins operation, drawing cleaning fluid from the cleaning fluid storage tank 30. The cleaning fluid is then transported through pipes to the distributor 33, and finally sprayed out from multiple nozzles on the distributor 33. Simultaneously, as the cleaning fluid is sprayed, the operator grips the handles of the installation platform 1 with both hands and pushes the platform forward with even force. During this movement, the scraper 35 passes over the switch rail. Because magnetic blocks 36 are installed near the scraper 35, they generate a magnetic field, which attracts the magnetic powder remaining on the switch rail. Then, the continuously sprayed cleaning fluid washes away the remaining impurities and attracted magnetic powder from the switch rail surface, thus completing the entire inspection and cleaning process.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
