Problems solved by technology

[0003] The existing methods of measuring the eccentricity of rails and bridges generally use manual measurement with a tape measure or a tape measure, and then calculate the results based on the measurement results and implement corresponding maintenance measures based on the results. However, this measurement method is inefficient and requires many People cooperate with the work, and the measurement results are not accurate enough

Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0034] In the present invention, it should be understood that the orientations or positional relationships indicated by the terms "central", "facing", "vertical", "horizontal", "deviating from", "outside", "inside" etc. are based on the drawings The orientation or positional relationship shown also corresponds to the orientation or positional relationship actually used; the orientation words used such as "up, down, left, and right" usually refer to the up, down, left, and right shown in the accompanying drawings. ; It is only for the convenience of describing the present invention and simplifying the description, and does not indicate that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of ...

Abstract

The invention relates to the field of rail measurement, in particular to an eccentric distance measuring system of a rail center and a bridge center. The measuring system is used for acquiring a distance delta between the center of the rail along a width direction and the center of the bridge along a width direction. When being in use, the measuring system can be installed on a to-be-measured bridge or rail at a proper orientation; a first length measuring device, a second length measuring device, a third length measuring device, a fourth length measuring device, a first laser range finder, asecond laser range finder, a third laser range finder, and a fourth laser range finder are used for measuring lengths corresponding to all segments conveniently; and then the distance delta is calculated based on the measured lengths corresponding to all segments. Therefore, one-by-one manual measurement of needed dimensions by measuring tools like a tape measure or a flexible ruler is avoided, sothat the measurement efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the field of rail measurement, in particular to a measurement system for the eccentricity between the center of the rail and the center of a bridge. Background technique [0002] The center deviation between the rails laid on the railway bridge and the bridge girder is very important to the safety of the bridge operation. Therefore, after a period of time, the railway needs to be inspected and maintained. The center deviation distance between the rails and the bridge girder needs to be detected. , especially for the maintenance of old bridges and curved bridge tracks, it is necessary to carry out various restoration work such as derailment and diversion every year, and it is necessary to detect the center deviation distance between the rail and the bridge girder before and after the track maintenance. [0003] The existing methods of measuring the eccentricity of rails and bridges generally use manual measurement with a tape me...
