Description
Technical field
the utility model belongs to railroad survey technical field, is specifically related to a kind of orbit measurement tradition to vector distance measuring and testing device.
Background technology
The smooth degree of railroad track refers to that the height that track is occurred rises and falls and left and right offsets, and affects the normal traveling of train because train orbits and the change of track bed for a long time.Along with improving constantly of train running speed, for realizing safety and the comfortableness of train operation, particularly the ride comfort of high speed railway track directly affects the safety of bullet train with steady, the design and construction of circuit must accomplish high ride, railroad requires more and more higher to railway irregularity state parameter, therefore particularly seems important to the detection of rail smooth degree with maintenance.
At present, the detection for railroad track smooth degree adopts the mode of track geometry status measuring instrument to carry out more, i.e. rail measuring apparatus, and this instrument need be measured to vector distance accurately to the Rail in walking process, to realize the comprehensive detection to orbital forcing.
Summary of the invention
The purpose of this utility model is to provide a kind of orbit measurement tradition to vector distance measuring and testing device, and the meter wheel tracking of matching track measuring instrument carries out Measurement accuracy to vector distance.
The technical scheme that the utility model adopts is:
A kind of orbit measurement tradition, to vector distance measuring and testing device, is characterized in that:
