A mobile double-track flaw detection device and its use method

Abstract

The invention discloses a mobile double-track flaw detection device, which includes a mobile base, a roller is installed at the lower end of the mobile base, and the roller is fixed on the mobile base through a fixing seat, and a flaw detection device is arranged at the front end of the mobile base. The flaw detection device includes a flaw detection frame, the flaw detection frame is fixedly connected with the mobile base through a pushing device, flaw detection wheels are arranged on the lower side of both ends of the flaw detection frame, a flaw detector seat is installed above the flaw detection wheel, and the flaw detector The front end of the seat is provided with a track front guide device, which is installed at the front end of the flaw detection wheel. The track front guide device includes a track front guide frame, a first flaw detector is installed on the track traction frame, and a double track flaw detection positioning device It can carry out mobile and efficient flaw detection on the track, improve the flaw detection efficiency, greatly increase the flaw detection area of ​​the track, effectively reduce the occurrence of later accidents, improve the accuracy of flaw detection at the same time, greatly reduce the missed detection rate of flaw detection, and ensure the driving safety of the track.

Description

technical field [0001] The invention relates to the technical field of rail flaw detection, in particular to a mobile double-rail flaw detection device and a method for using the same. Background technique [0002] Rail flaw detection refers to the use of flaw detection equipment to detect fatigue defects and welding defects at the rail head and rail waist position. The detected content includes rail scratches, etc. When the flaw detection equipment slides on the rail, it can The damage signal, mileage signal and line characteristic signal of the rail are recorded. According to the information recorded by the flaw detection equipment, the inspector can quickly determine the position and size of the rail damage, and can also determine the extent of the rail damage. Line mileage, using the above-mentioned track detection method, can find the position of track damage in time and repair it in time to ensure that the train runs safely on the intact track, thereby avoiding unneces...

[0002] Rail flaw detection refers to the use of flaw detection equipment to detect fatigue defects and welding defects at the rail head and rail waist position. The detected content includes rail scratches, etc. When the flaw detection equipment slides on the rail, it can The damage signal, mileage signal and line characteristic signal of the rail are recorded. According to the information recorded by the flaw detection equipment, the inspector can quickly determine the position and size of the rail damage, and can also determine the extent of the rail damage. Line mileage, using the above-mentioned track detection method, can find the position of track damage in time and repair it in time to ensure that the train runs safely on the intact track, thereby avoiding unnecessary safety accidents, but in the existing flaw detection process Some are difficult to detect, and some are recorded during the flaw detection process, but during the search process, there are checkmark errors in the content, which is difficult to find, and a second detection is required in the later stage. The detection range is restricted, which is not conducive to the safety of the track
