Description
Technical field
the utility model belongs to railroad survey technical field, is specifically related to a kind of simple detection rail frame of high speed railway track measuring instrument.
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, detection for railroad track smooth degree adopts the mode of track geometry status measuring instrument to carry out more, but, this measuring instrument is needing to carry out applicability adjustment for during the wireline inspection such as Ballast track, non-fragment orbit, subway, light rail, Long-Time Service also can affect its certainty of measurement, therefore, need the calibrating installation of a standard to carry out the regular calibrating of timing to measuring instrument, to guarantee its reliability in field operation measuring process and accuracy.But the caliberating device for calibration measurements instrument is generally indoor standardization device, real-time calibration cannot be carried out at operation field.
Summary of the invention
The purpose of this utility model is to provide a kind of simple detection rail frame of high speed railway track measuring instrument, can carry out real-time calibration measurements at operation field to rail measuring apparatus.
The technical scheme that the utility model adopts is:
A simple detection rail frame for high speed railway track measuring instrument, is characterized in that:
Include the perpendicular crossbeam of longeron and longeron side central authorities, between crossbeam end side and longeron two ends, be provided with twice cant beam;
The two ends end face of longeron is provided with road wheel cushion cap, and in the middle part of longeron, top and crossbeam end side end face are provided with meter wheel cushion cap.
Meter wheel cushion cap bottom surface is provided with leveling ruler cushion cap;
The longitudinal two ends of leveling ruler cushion cap are provided with the boss for placing leveling ruler;
Leveling ruler cushion cap is laterally provided with for adding the boss of rail to backing plate near the end of crossbeam.
Be provided with height gauge cushion cap between crossbeam and cant beam, what be positioned at stringer sides is height gauge avris cushion cap, and what be positioned at middle part is cushion cap in the middle part of height gauge.
The bottom at longeron two ends and the bottom of crossbeam end side are provided with firm banking, are fixed on bottom surface by lower margin.
The utility model has the following advantages:
The utility model compact conformation is reasonable, and volume is little, lightweight, is convenient to field operation and carries, and can carry out on-the-spot real-time calibration to rail measuring apparatus.Owing to meter wheel cushion cap and road wheel cushion cap being strictly arranged in same level, in conjunction with the leveling ruler on leveling ruler cushion cap and height gauge cushion cap and height gauge, the calibrating of gauge, height and superelevation can be carried out to rail measuring apparatus.Add vertical backing plate at the medial surface of meter wheel cushion cap, energy tracking is to carrying out simulating and detecting.Effectively improve operating efficiency, achieve the on-the-spot field operation calibrating to rail measuring apparatus and maintenance, extend the application life of rail measuring apparatus, improve the Measurement reliability of rail measuring apparatus.
