Abstract
The invention relates to a straight ruler suspension structure for a high speed railway track measurement instrument. A cross beam and a longitudinal beam of the track measurement instrument have a fixed connection relationship ordinarily, measurement wheels and traveling wheels are positioned on the same plane, and recessing or bulging data cannot be acquired. The straight ruler suspension structure comprises a measurement part and a traveling part, wherein the measurement part comprises the cross beam; the traveling wheels are arranged at two ends of the cross beam; each measurement wheel is arranged on the inner side of the corresponding traveling wheel; the traveling part comprises an upper cross beam cover plate arranged at the top of the cross beam; the front and rear ends of one side of the upper cross beam cover plate are connected with an upper longitudinal beam cover plate through an inter-beam locking device; a traveling wheel is arranged on the inner side of the end part of the upper longitudinal beam cover plate, and a guide wheel is arranged on the inner side of the traveling wheel; the cross beam of the measurement part is suspended on the traveling part and the upper cross beam cover plate through a middle suspension shaft. According to the straight ruler suspension structure for the high speed railway track measurement instrument, the cross beam can rotate around the suspension shaft in the upper cover plate; when a recess or a bulge is formed between the front traveling wheel and the rear traveling wheel of the longitudinal beam, the measurement wheels at the end parts of the cross beam can abut against the track to acquire geometrical information, so that the comprehensive smoothness detection of the track is completed.
Description
Technical field
the invention belongs to railroad survey technical field, be specifically related to a kind of high speed railway track measuring instrument ruler suspended structure.
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, i.e. rail measuring apparatus, this instrument is generally made up of crossbeam and total amount, on longeron, rear and front end arranges two road wheels, two ends, crossbeam left and right arrange two road wheels, and crossbeam can measure rail to vector distance and gauge displacement, thus carries out comprehensive detection to ride comfort.The transverse and longitudinal beam of rail measuring apparatus is generally consolidation relation, when running into rear and front end on longeron, the situation having rail level recessed between two road wheels is set, the meter wheel of this side of crossbeam is still in same plane with the road wheel of longeron, and recessed geometric parameter just cannot be gathered by the meter wheel on crossbeam.
Summary of the invention
The object of this invention is to provide a kind of high speed railway track measuring instrument ruler suspended structure, make the meter wheel on crossbeam the geometric parameter that rail level is recessed can be detected.
The technical solution adopted in the present invention is:

The road wheel of running part and the road wheel of measurement section longeron end are on the same line;
The crossbeam of measurement section hangs on running part and crossbeam upper cover plate by the suspended axle at middle part.
Suspended axle is along rail to through crossbeam and crossbeam upper cover plate, or suspended axle divides two sections to be arranged at crossbeam upper cover plate rail to both sides;
Rolling bearing is provided with between the axis hole of suspended axle and crossbeam and crossbeam upper cover plate.
Displacement transducer is provided with inside the meter wheel of measurement section longeron end.
Measurement section longeron is connected with piston rod to inside the meter wheel of side end.
The air spring for making crossbeam self adaptation gauge is provided with in crossbeam.
The present invention has the following advantages:
Rail measuring apparatus is divided into measurement section and running part by the present invention, by the upper cover plate of crossbeam and longeron consolidation, and crossbeam is hung in upper cover plate by suspended axle, crossbeam can be produced around suspended axle in upper cover plate rotate, when there is the situation of recessed or upper drum between former and later two road wheels of longeron, above-mentioned geological information near track, can collect by the meter wheel of beam-end, completes the comprehensive detection of orbital forcing.
