Rail base material and welding seam scanning integrated trolley

Abstract

The invention discloses a rail base material and welding seam scanning integrated trolley which comprises a trolley body, and further comprises a base metal scanning mechanism, a welding seam scanning mechanism and an ultrasonic host arranged on the trolley body. The trolley is compact in structure, space is fully utilized, the overall structure is small, and a single person can conveniently conduct up-and-down operation. Welding seam scanning can be completed only through forward and reverse scanning of the welding seam scanner, operation is easy, and efficiency is high. According to the welding seam scanning device, scanning is started through automatic control, an operator only needs to start scanning, scanning can be automatically completed, and missing detection and false alarm caused by manual operation are eliminated. Base material scanning and welding seam scanning are integrated, two welding seam scanning modes of rail head serial scanning and rail bottom scanning are integrated, the number of probes is effectively reduced, the space is optimized, and operation is simplified.

Description

technical field [0001] The invention relates to a device capable of performing ultrasonic scanning flaw detection on rail parent materials and welding seams. Background technique [0002] my country's track flaw detection operations are divided into track base metal flaw detection and track weld flaw detection. The base metal flaw detection refers to the ultrasonic scanning flaw detection of the rail body, and the weld seam flaw detection refers to the scanning flaw detection of the rail weld seam. The two work independently, and some parts are repeatedly tested, which takes up a lot of manpower and material resources. [0003] Welds are divided into on-site welding and factory welding. Weld seam inspection is mainly to inspect on-site welding, and the inspection is performed twice a year. The inspection cycle is long and there are potential safety hazards. [0004] Secondly, the procedure of weld flaw detection is complicated, and the weld rail head, rail waist, and rail b...

AI Technical Summary

Problems solved by technology

[0003] Welds are divided into on-site welding and factory welding. Weld seam flaw detection is mainly to detect on-site welding. The inspection is performed twice a year. The inspection cycle is long and there are potential safety hazards.

[0004] Secondly, the procedure of weld flaw detection is complicated, and the weld rail head, rail waist, and rail bottom need to be inspected separately, which takes a lot of time, and the inspection process and method are relatively simple

However, the maintenance of newly added seamless lines and service tracks will produce a large number of new welds every year, while the reserve and replenishment of flaw detection personnel has not kept up with it, and the quality of weld flaw detection operations cannot be effectively guaranteed

[0005] In addition, in the existing flaw detection equipment, manual scanning is used for the detection of welds, but this detection method has a slow detection speed and is greatly influenced by human factors, resulting in a low detection rate and a high false alarm rate.
