Description

TECHNICAL FIELD

[0001] The utility model relates to track detection technical field, especially a kind of high-speed rail track welding performance rapid detection equipment. BACKGROUND

[0002] In recent years, the high-speed rail mileage of our country grows continuously, and the high-speed rail speed is also continuously promoted. Behind this, the high-speed rail track detection work silently guards the driving safety of high-speed train, and the quality detection of rail welding joint is an important link to ensure the safe operation of railway, and the defects of high-speed rail welding connection part will affect the stable operation of train on track, cause serious consequences, while sighing the development of high-speed rail technology, also need to pay close attention to and explore the innovation of high-speed rail track detection technology.

[0003] Although the current domestic track detection technology is constantly progressing, it still has its limitations: high-speed rail track detection can only be carried out at night when the train is out of operation, the requirements for detection equipment and technology are more stringent, the detection efficiency needs to be improved, the measurement accuracy needs to be more accurate, and the excessive dependence on environment, etc.

[0004] And at present, the most common detection method for nondestructive testing of rail weld is ultrasonic testing. The ultrasonic nondestructive testing can detect cracks, white spots, delamination, pores, incomplete penetration and other defects in the rail, but the ultrasonic testing technology also has its own limitations. The structure of rail weld itself is "H" shape. The probe commonly used for ultrasonic testing is used to detect one side of the rail, which is difficult to effectively reflect all internal defects, and is easy to cause missed detection.

[0005] Therefore, the high-speed rail track welding performance rapid detection equipment is provided to meet the needs. UTILITY MODEL CONTENT

[0009] Preferably, the rack is rectangular, and the rack is vertically installed at the front end of the inspection car.

[0010] Preferably, the screw rod is vertically installed in the inside of the rack, the screw rod vertically extends through the frame to the inside lower end of the rack, and the frame is movably connected with the rack through the screw rod.

[0011] Preferably, the guide seat and the pivot are vertically arranged, and the guide seat is movably connected with the fixed seat through the pivot.

[0012] Preferably, the support is in the shape of "L", and the support extends laterally to the outer end of the inspection car through the connecting rod.

[0013] Preferably, the support vertically extends through the connecting seat of the upper end of the briquetting to the inside of the connecting seat, and the extension spring is vertically installed between the support and the briquetting.

[0014] Preferably, the support is provided with the crossbeam on the left and right sides, and the support rod and the ultrasonic probe extend outward to the side lower end of the briquetting through the crossbeam.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, the frame can move vertically along the rack through the screw rod, so as to adjust the height of the inspection structure to adapt to various track inspection environments. The detection structure at the outer end of the connecting rod can act on the track. When the inspection car travels along the track, the briquetting can move against the surface of the rail to check the surface flatness. When a weld joint is encountered, the briquetting is lifted to compress the extension spring, the other end of the extension spring presses the pressure sensor, the pressure sensor can detect the fluctuation of the pressure, thereby detecting the weld joint flatness of the rail, reducing the burden of the detection personnel, improving the efficiency of the detection work, and providing strong support for track maintenance work.

[0017] In the above scheme, when the pressure block is pressed against the upper surface of the rail, the support rod and the ultrasonic probe are located on the left and right sides of the outer end of the rail. The ultrasonic probe emits ultrasonic waves along the left and right sides of the outer end of the rail. When it encounters damage in the rail, it will generate signals such as reflection and scattering. By analyzing the signal transmission, the damaged location and degree can be found efficiently and accurately. Effective reflection is achieved outside the rail weld with the "I" shape structure, reducing the chance of missed detection and effectively improving the accuracy of detection.
