Rail cant measurement scale and measurement method for rail traffic

Abstract

The invention relates to the scientific field of engineering technologies of rail traffic such as a railway and in particularly relates to a rail cant measurement scale and a measurement method for the rail traffic. The rail cant measurement scale is characterized in that a handle is arranged at the center of a main beam, two groups of depth measurement scales which are parallelly arranged at equal intervals are arranged at left and right equidistant positions on the side surface of the main beam, two groups of auxiliary rail base scales are arranged at positions corresponding to the positive directions of scale sharps of the two groups of the depth measurement scales, two limiting blocks are arranged in the middle of each group of two depth measurement scales on the main beam, and an abrasion resistant block is arranged at a position where the main beam is contacted with a rail surface. By means of a geometric principle that a height difference is measured through a spot-line distance, traditional manual verification is replaced, the measurement accuracy is high and can be corrected to millimeters, values can be simply and visually read, a rail cant can be rapidly calculated, the visual measurement of the rail cant can be achieved, errors can be real-timely found, states of a rail can be timely adjusted, and compared with speeds of manual adjusting in existing methods, the speed of the method is increased by 3-4 times.

Description

[technical field] [0001] The invention relates to the scientific field of rail traffic engineering technology such as railways, in particular to a rail bottom slope measuring ruler and a measuring method related to rail traffic. [Background technique] [0002] Urban rail transit is an important part of urban public transportation. With the development of the national economy and the acceleration of urbanization, the development of rail transit is also accelerating. The structure of rail transit also adopts short sleeper track bed structure. [0003] At present, domestic long sleeper tracks generally use prefabricated sleepers or iron backing plates to set the rail bottom slope, and short sleepers use rail adjustment brackets to set the rail bottom slope. [0004] For the integral ballast bed with short sleepers, before concrete pouring, the positions of the rails and sleepers on both sides are relatively free. The gauge rods cannot measure the value of the rail bottom slop...
