Description

Technical Field

[0001] The utility model relates to the technical field of rail weld detection, in particular to a rail waist profiling fitting device suitable for rail weld detection. Background Art

[0002] In recent years, my country's railway industry has flourished. By the end of 2023, the national railway operating mileage will reach 159,000 kilometers, of which the high-speed railway operating mileage will reach 45,000 kilometers. A large number of rail welds connect the rails one by one, and the seamless lines formed allow high-speed trains to run safely and smoothly on the railway. The quality and safety of rail welds are particularly important in the operation of high-speed railways. The railway management department has special inspection personnel to regularly perform ultrasonic inspections on rails and rail welds on the railway. As an irregular workpiece, the rail welds require a relatively complicated process for comprehensive ultrasonic inspection. At the same time, considering the large number of rail welds on the railway, the working time for inspection is limited. Therefore, it is of great significance to improve the efficiency of ultrasonic inspection of rail welds.

[0003] The traditional ultrasonic detection of rail bottom angle of rail weld divides the rail bottom angle into 6 detection areas. A K2.5 ultrasonic probe is used to perform longitudinal moving probe scanning at different deflection angles and positions. The upper half of the weld is detected by secondary waves, and the lower half of the weld is detected by primary and tertiary waves. From the scanning requirements, it can be seen that 6 scans are required for 1 rail bottom angle, and 24 scans are required for the four rail bottom angles on both sides of the weld to complete the comprehensive detection of the weld bottom angle.

[0004] Traditional scanning of the bottom angle of welded rails requires the use of an ultrasonic probe to perform longitudinal back-and-forth scanning at multiple positions and angles. The detection effect, accuracy of the probe position, accuracy of the angle, and stability of the probe movement scanning are relatively dependent on the operating level of the flaw detector itself.

[0005] The bottom corner of the welded rail has multiple slopes, and it is difficult to scan the entire area. In particular, how to make the automated device fit the rail waist better to complete the scanning is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0006] The utility model aims to solve the deficiencies of the prior art and provide a profiling device that can fit the waist of a rail at multiple angles, thereby making the scanning of a scanning device more stable.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a rail waist profiling fitting device suitable for rail weld detection, comprising:

[0008] The main body is a T-shaped structure, including a first fitting portion and a mounting portion, the first fitting portion and the mounting portion are perpendicular to each other, a plurality of first rollers are provided on one side of the surface of the first fitting portion, the first rollers are fitted with the upper part of the waist of the rail, an encoder is installed on one side of the mounting portion, the top of the encoder is connected to a rubber wheel, the rubber wheel is fitted with the middle part of the waist of the rail, the bottom end of the mounting portion is bent and extended toward one side of the bottom end of the encoder to form a second fitting portion, a plurality of second rollers are provided on the bottom surface of the second fitting portion, and the second rollers are fitted with the bottom of the waist of the rail.

[0009] Preferably, a first magnet is disposed between adjacent first rollers, and the first magnet is embedded in a side surface of the first fitting portion.

[0010] Preferably, a second magnet is disposed between adjacent second rollers, and the second magnet is embedded in a side surface of the second fitting portion.
