Detection ruler of torsion obliquity of rail top of steel rail and method for detecting torsion obliquity of rail top of steel rail on line

Abstract

The invention relates to a detection ruler of torsion obliquity of the rail top of a steel rail and a method for detecting the torsion obliquity of the rail top of the steel rail on a line. The upper end of a guide rod of the detection ruler is fixedly provided with a digital display, and the middle part is provided with a bar-shaped hole; the upper end of an altitude scale is inserted and arranged on the digital display, and the lower end is provided with a round hole; the tail end of a detection templet of a rail head is provided with a shaft hole, and the front end is provided with a circular arc-shaped gap which is matched with the rail head at the half side of the steel rail; and a pin shaft penetrates through the round hole, the bar-shaped hole and the shaft hole sequentially and hinges the lower end of the altitude scale, the tail end of the detection templet of the rail head and the guide rod together. The invention measures the torsion obliquity of the steel rail indirectly by calculating the relative rotating obliquity H / L of the detection templet of the rail head, enhances the detection accuracy of the torsion obliquity of the rail top surface of the steel rail, solves the problem that the torsion obliquity of the rail top surface of the steel rail on a known line is difficult to detect, ensures the smoothness of transition at the joint parts of the steel rail and enhances the safety and the smoothness of a train and the comfort of passengers during the high-speed pass of the train.

Description

technical field [0001] The invention relates to a rail top torsion inclination detection ruler and a method for detecting the torsion inclination of a rail top of a rail. Background technique [0002] In the laying of railway lines, a rail bottom slope with a certain slope relative to the track plane is generally provided. The turnout is the transitional connection of the crossing part of the railway line. The main components are the tip rail and the core rail. The rear end is connected with other lines by twisting, so that the wheels can transition smoothly. In the existing turnout production, the heel end of the AT rail is pressed and twisted to a certain inclination to maintain the same inclination as the line rail, and then connected by welding or joint splints. At present, the inclination of the profiled section rail bottom is detected by the front end AT rail bottom as the datum plane to determine the torsional inclination of the entire heel end, which may easily caus...

AI Technical Summary

Problems solved by technology

At present, the inclination of the rail bottom of the profiling section is detected by using the AT rail bottom at the front end as the reference plane to determine the torsional slope of the entire heel end, which may easily cause the actual inclination of the rail top to be inconsistent with the inclination of the rail bottom, which will seriously affect the driving quality. negative influence

For the line being laid or already in operation, it is difficult to measure the actual torsional slope of the rail head due to the difficulty in selecting the datum plane
