Description
Technical Field
The utility model relates to a technical field that the railway was measured, concretely relates to portable rail corrugation detection device.
Background
The wave-shaped abrasion of the steel rail, called wave grinding for short, is a main form of rail damage, and refers to the phenomenon of uneven abrasion which appears on the longitudinal surface of a steel rail running belt and is regularly convex and concave like waves. About 40% of rail structures in the world can cause the damage of corrugation, and the high maintenance cost and the great potential safety hazard enable the rail corrugation problem to become a problem to be solved in the world rail traffic industry. Due to the numerous influencing factors, the research of rail corrugation, which lasts for nearly one hundred years, is still a challenging problem to date.
With the rapid development of rail transit in China, the requirement on the transport capacity of trains is continuously improved, the speed of the trains is increased once and again, the axle load of the trains is continuously increased, the traffic density of the trains is increased, and the rail corrugation phenomenon is increasingly intensified. The corrugation causes vibration of rail vehicles and noise, increases fatigue of rolling of wheel rails, shortens service lives of steel rails and wheels, leads to continuous improvement of train transportation cost, even threatens the transportation safety of trains, and is an important problem which troubles rail traffic of railways and the like.
At present, the steel rail section profile detection applied in China mainly adopts a static detection mode, and specific detection methods of the detection mode can be divided into two types, namely contact type and non-contact type. The contact type steel rail section profile detection equipment is in contact with the detected surface of the steel rail, and the characteristic position information or the complete steel rail profile of the steel rail profile is directly obtained. The detection method of the profile of the section of the steel rail used by related departments of railways in China is mostly in a contact type, such as a contact clamp and the like. The non-contact steel rail section profile detection equipment realizes the acquisition of steel rail profile data under the condition of not contacting the surface of the measured steel rail. The portable steel rail detector RML3000 produced by the Swiss ELAG company is taken as a representative, and the detection of the steel rail profile is realized by adopting a laser ranging sensor. Related departments of railways in China slightly apply non-contact electronic instruments for detection, for example, an GKY10-X type steel track profile grinding analyzer which is jointly developed by an overhaul section of Wuhan large-scale road maintenance machinery of Wuhan railway administration and Wuhan university integrates optical, measurement, image analysis and data processing technologies, and the detection efficiency is greatly improved. The contact type steel rail section profile detection method depends on manual work, and is low in measurement efficiency and poor in accuracy. Although the accuracy of non-contact steel rail section profile detection is improved, the price of an electronic instrument is high, and the applicability of the non-contact steel rail section profile detection to domestic steel rail profile detection is poor.
