Description

Technical Field

[0001] This utility model relates to the field of welding inspection technology, and in particular to a precise testing device for the welding performance of high-speed railway tracks. Background Technology

[0002] High-speed rail tracks are an important component of high-speed railways. Their design and construction are designed to meet the needs of high-speed trains for smooth, fast and safe operation. During use, high-speed rail tracks may break, requiring welding repairs.

[0003] After welding high-speed rail tracks, it is necessary to inspect the weld joints to ensure the accuracy of the welded tracks. In the existing technology, the inspection of high-speed rail tracks usually uses ultrasonic flaw detectors to detect whether there are cracks at the weld joints. However, during the inspection process, the ultrasonic flaw detectors are usually manually held by hand to detect the weld joints, which is inconvenient and affects the accuracy of the inspection. Therefore, a high-speed rail track welding performance precision inspection device is designed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a high-speed rail track welding performance precision testing device.

[0005] The technical problem to be solved by this utility model is to provide a precise testing device for the welding performance of high-speed rail tracks, which solves the problem that the accuracy of testing is affected by the use of a handheld flaw detector probe to inspect the weld joints when testing the weld joints of high-speed rail tracks.

[0006] This utility model provides a high-speed rail track welding performance precision testing device, including a testing device, a connecting rod and a sliding device. The right end of the testing device is fixedly provided with a sliding device that can slide along the track through the connecting rod.

[0007] The detection device includes a first n-shaped frame, a display screen, an ultrasonic flaw detector, and a magnetic particle flaw detector. The display screen is embedded in the center of the upper surface of the first n-shaped frame. Ultrasonic flaw detectors are installed on the left, right, and upper sides of the first n-shaped frame. A magnetic particle flaw detector is installed on the lower inner side of the first n-shaped frame.

[0008] Preferably, the ultrasonic flaw detector, the magnetic particle flaw detector, and the display screen are electrically connected.

[0009] Preferably, the sliding device includes a second n-shaped frame, a positioning rod, a fixing plate, a spring, a handle, and rollers. Positioning rods are provided through the lower surface of both sides of the second n-shaped frame. A fixing plate is fixedly provided at the end of the positioning rod. A spring is fixedly provided between the fixing plate and the side of the second n-shaped frame. A handle is fixedly provided on the outer surface of the fixing plate. Rollers are installed on the bottom surface of the second n-shaped frame.

[0010] Preferably, the distance between the bottom surface of the roller and the positioning rod is equal to the thickness of the high-speed rail track head, and the width of the second n-shaped frame is equal to the width of the high-speed rail track head.

[0011] Preferably, the positioning rod extends through the interior portion of the second n-shaped frame in an inclined shape with a reduced thickness at the bottom.

[0012] Preferably, when the spring is in its naturally extended state, the lower part of the positioning rod completely penetrates the second n-shaped frame, and the upper part of the positioning rod extends out of the second n-shaped frame.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] 1. This utility model, by setting up a sliding device and a detection device, allows for the inspection of high-speed rail tracks. By installing the sliding device on the high-speed rail track and then sliding the sliding device along the track, the detection device moves to the weld joint of the high-speed rail track. The detection device performs flaw detection on the weld joint of the high-speed rail track, ensuring the stability and accuracy of the detection.

[0015] 2. This utility model, by incorporating a detection device, simultaneously inspects the weld joints of high-speed rail tracks using ultrasonic flaw detectors located on the left, right, and top sides of the first n-shaped frame, and displays the results on a screen, ensuring accuracy during inspection. Furthermore, by dispersing magnetic powder on the high-speed rail track and applying magnetism to the weld joint using a magnetic powder flaw detector, the individual particles on the magnetized weld joint are observed, revealing cracks and defects, further guaranteeing the precision of the inspection.

[0016] 3. This utility model incorporates a sliding device. When the sliding device is installed on the high-speed rail track, the second n-shaped frame is aligned with the rail head of the high-speed rail track and pressed downwards, causing the second n-shaped frame to fit onto the rail head. The rail head of the high-speed rail track presses against the positioning rod, causing the positioning rod to move outwards from the second n-shaped frame. The spring 303 is compressed until the upper surface of the positioning rod is level with the bottom of the rail head. The spring force then ejects the positioning rod, at which point the bottom of the roller contacts the upper surface of the rail head, achieving the installation effect of the sliding device. The sliding device moves left and right, and the roller rolls on the high-speed rail track, facilitating the movement of the detection device and ensuring the accuracy of the detection device in inspecting the welded joints of the high-speed rail track.

[0026] Example:

[0027] like Figures 1-6As shown, an embodiment of this utility model provides a high-speed rail track welding performance precision testing device, including a testing device, a connecting rod 2 and a sliding device. The right end of the testing device is fixedly provided with a sliding device that can slide along the track through the connecting rod 2.

[0028] The testing device includes a first n-shaped frame 1, a display screen 101, an ultrasonic flaw detector 102, and a magnetic particle flaw detector 103. The display screen 101 is embedded in the center of the upper surface of the first n-shaped frame 1. The ultrasonic flaw detectors 102 are installed on the left, right, and upper sides of the inside of the first n-shaped frame 1. The magnetic particle flaw detector 103 is installed on the lower inner side of the first n-shaped frame 1.

[0029] By incorporating a sliding device and a detection device, when inspecting high-speed rail tracks, the sliding device is installed on the high-speed rail track and then slid along the track to move the detection device to the weld joint of the high-speed rail track. The detection device performs flaw detection on the weld joint of the high-speed rail track, ensuring the stability and accuracy of the detection.

[0030] By incorporating a detection device, when inspecting the welded joints of the high-speed rail track, ultrasonic flaw detectors 102 located on the left, right, and top sides of the welded joint are used to simultaneously detect the welded joint and display the results on a screen 101, ensuring the accuracy of the inspection. Furthermore, by dispersing magnetic powder on the high-speed rail track and applying magnetism to the welded joint using a magnetic particle flaw detector 103, the individual particles on the magnetized welded joint are observed, revealing cracks and defects in the welded joint and further ensuring the precision of the inspection.

[0031] In this embodiment, the ultrasonic flaw detector 102, the magnetic particle flaw detector 103, and the display screen 101 are electrically connected.

[0032] In this embodiment, the sliding device includes a second n-shaped frame 3, a positioning rod 301, a fixing plate 302, a spring 303, a handle 304, and a roller 305. The positioning rod 301 is provided through the lower surface of both the left and right sides of the second n-shaped frame 3. The fixing plate 302 is fixedly provided at the end of the positioning rod 301. The spring 303 is fixedly provided between the fixing plate 302 and the side of the second n-shaped frame 3. The handle 304 is fixedly provided on the outer surface of the fixing plate 302. The roller 305 is installed on the bottom surface of the second n-shaped frame 3.

[0033] In this embodiment, the distance between the bottom surface of the roller 305 and the positioning rod 301 is equal to the thickness of the high-speed rail track head, and the width of the second n-shaped frame 3 is equal to the width of the high-speed rail track head, so that the second n-shaped frame 3 can be fitted onto the high-speed rail track head, allowing the roller 305 to roll on the upper surface of the high-speed rail track head.

[0034] In this embodiment, the positioning rod 301 passes through the interior portion of the second n-shaped frame 3 and is inclined with the thickness of the lower component decreasing.

[0035] In this embodiment, when the spring 303 is in its naturally extended state, the lower part of the positioning rod 301 completely penetrates the second n-shaped frame 3, and the upper part of the positioning rod 301 extends out of the second n-shaped frame 3, which facilitates the positioning rod 301 to move to the outside of the second n-shaped frame 3.

[0036] By incorporating a sliding device, when installing the sliding device on the high-speed rail track, the second n-shaped frame 3 is aligned with the rail head of the high-speed rail track and pressed downwards, causing the second n-shaped frame 3 to fit onto the rail head of the high-speed rail track. The rail head of the high-speed rail track presses against the positioning rod 301, causing the positioning rod 301 to move outwards from the second n-shaped frame 3. The spring 303 is in a compressed state until the upper surface of the positioning rod 301 is at the same horizontal height as the bottom of the rail head of the high-speed rail track. The elastic force of the spring 303 then ejects the positioning rod 301. At this point, the bottom of the roller 305 contacts the upper surface of the rail head of the high-speed rail track, achieving the installation effect of the sliding device. The sliding device moves left and right, and the roller 305 rolls on the high-speed rail track, facilitating the movement of the detection device and ensuring the accuracy of the detection device in inspecting the welded joints of the high-speed rail track.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
