A light rail flaw detection trolley

Abstract

The invention relates to flaw detection equipment for a railway rail, in particular to an automatic flaw detection trolley for the railway rail. The automatic flaw detection trolley comprises a drive trolley part and a flaw detection trolley part. The drive trolley part is composed of drive wheels, a trolley body, seat chairs, pedal plates, an electrical system, a workbench and the like. The flaw detection trolley part is composed of wheels, a flaw detection trolley frame, a flaw detection wheel assembly, elastic telescopic supports, a material platform and the like. The automatic flaw detection trolley for the railway rail is characterized in that the flaw detection trolley for the light rail is foldable and light in weight and can get on and off the rail conveniently; flaw detection devices can be increased or decreased at any time according to needs of railway busy sections, and the levels and angles of the flaw detection wheels can be adjusted; and meanwhile, the positions, relative to the rail, of the flaw detection wheels are not prone to varying due to the height difference of a curve rail, and the flaw detection precision is high.

[0002] Railway rail defects directly affect the safety of train operation. During the operation of the train, the rails will be rubbed and squeezed, causing slight deformation of the rails. In addition, there will be some trace defects inside the rails when they leave the factory. Defects such as cracks, slag falling, and fractures are prone to occur, and the internal defects of the rail will gradually increase. Under the action of fatigue stress, it is easy to break and seriously affect driving safety.

[0003] Now rail flaw detection is an important task in the railway engineering system. The ultrasonic flaw detection currently used includes: hand push ultrasonic flaw detector, which is convenient to go up and down the track, and the flaw detection speed is 2Km / h, which is relatively slow and low in efficiency; Although the efficiency reaches over 20Km / h, only one set of flaw detection wheels can be placed on the left and right sides, and the flaw detection equipment cannot be increased or decreased according to the stress of different road sections and rails. The angle of the flaw detection wheels cannot be adjusted, and the flaw detection effect is not very ideal. The cost of equipment and manpower is increased, and the weight of the trolley is more than 100Kg, which is inconvenient for getting on and off the road; there is also a large ultrasonic flaw detection vehicle with multiple sets of flaw detection wheels, which runs at a high speed, but some defects cannot be clearly found, and manual inspection is required. The price of this equipment is very expensive, and there are few road bureau configurations. Although the detection efficiency is high, it still needs manual verification, which affects the efficiency of use. The operation procedures are strict and cannot meet the needs.
