A Portable Rail Profile Measuring Device

Abstract

The invention discloses a portable rail profile measuring device, which is composed of upper, middle and lower parts stacked and joined. A detachable side panel is inserted on the top surface of the upper part. The middle part of the main body is provided with equal intervals along the left and right directions, and there are central threaded mounting holes through the upper and lower surfaces of the middle part of the main body. The internal thread is installed with a cylindrical measuring head, and the vertical position of the measuring head is adjustable. When in use, after splitting the upper, middle, lower, and side panels, install the side panels vertically on the middle from the middle to realize the alignment between the middle and the side of the rail; then use the measuring head to measure the profile of the rail; and the Multiple middle horizontal combinations are suitable for measuring rails of different widths. The invention adopts a modular design, which is convenient for assembly, disassembly and maintenance, and is easy to carry. Wing rail combination profile measurement and grinding quality evaluation.

Description

technical field [0001] The invention belongs to the technical field of engineering, in particular to a portable rail profile measuring device. Background technique [0002] Since the reform and opening up, my country's railways have achieved leapfrog development, with qualitative changes in railway operating speed, traffic volume, and vehicle types. At the same time, the interaction force between the wheel and the rail is becoming more and more complex, and the problems of rail corrugation, fatigue damage, side wear, and vehicle stability are becoming more and more prominent. In order to effectively control the occurrence and development of rail defects and prolong the service life of rails, the engineering department gradually promotes the rail profile grinding technology. Through the implementation of rail profile grinding, the wheel-rail contact relationship can be changed, and the occurrence and development of rail defects can be controlled from the root. However, how ...

However, how to comprehensively measure the rail profile and how to control the quality of the rail profile grinding process in real time restricts the further improvement of the rail profile grinding quality

[0003] At present, the commonly used profile measuring equipment includes laser type, mechanical profile measuring instrument and profile template. The first two types of profile measuring instruments have relatively high measurement accuracy, but they are expensive, difficult to popularize, inconvenient to carry, and can only measure Line rail profile; the latter profile template has low precision and can only evaluate the line rail profile without measurement function, and it is not easy to carry

Therefore, there is a lack of a portable, reasonably priced device that can measure the profile of the line rail, turnout tip / core rail combined profile, and can evaluate the grinding quality of the profile
