Description

High speed railway track measuring instrument ruler suspended structure
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 orbit for a long time due to train and the change of track bed, and the height making track occur rises and falls and left and right offsets, and affects the normal traveling of train.Along with improving constantly of train running speed, for realizing safety and the comfortableness of train operation, the particularly 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, railway irregularity state parameter is required more and more higher by railroad, and therefore the detection to rail smooth degree particularly seems important with safeguarding.
At present, the mode using track geometry status measuring instrument is detected more for railroad track smooth degree carry out, i.e. rail measuring apparatus, this instrument is typically 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 ride comfort is carried out comprehensive detection.The transverse and longitudinal beam of rail measuring apparatus generally consolidates relation, when running into rear and front end on longeron, the situation having rail level recessed between two road wheels is set, the wheel road wheel still with longeron of measuring of this side of crossbeam is in same plane, and recessed geometric parameter just cannot be taken turns by the measurement on crossbeam and be gathered.
Summary of the invention
It is an object of the invention to provide a kind of high speed railway track measuring instrument ruler suspended structure so that measuring on crossbeam is taken turns and the geometric parameter that rail level is recessed can be detected.
The technical solution adopted in the present invention is:
High speed railway track measuring instrument ruler suspended structure, it is characterised in that:
Including measurement portion and running part;
Measurement portion includes that crossbeam, crossbeam two ends are provided with road wheel, is provided with measurement wheel inside road wheel;
Running part includes the crossbeam upper cover plate that cross rail top is arranged, and being connected by locking device between beam before and after crossbeam upper cover plate side has longeron upper cover plate, longeron upper cover plate tip inside to be provided with road wheel, be provided with directive wheel inside road wheel;
The road wheel of running part nearly longeron end is with the road wheel of measurement portion longeron end on the same line;
The crossbeam in measurement portion 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;
It is provided with rolling bearing between the axis hole of suspended axle and crossbeam and crossbeam upper cover plate.
It is provided with displacement transducer inside the measurement wheel of measurement portion longeron end.
Measurement portion longeron has piston rod to connecting inside the measurement wheel of side end.
Crossbeam is provided with the air spring for making crossbeam self adaptation gauge.
The invention have the advantages that
Rail measuring apparatus is divided into measurement portion and running part by the present invention, the upper cover plate of crossbeam is consolidated with longeron, and crossbeam is hung in upper cover plate by suspended axle, crossbeam can be produced around suspended axle in upper cover plate rotate, when the situation of recessed or upper drum occurs between former and later two road wheels of longeron, above-mentioned geological information can be collected against track, complete the comprehensive detection of orbital forcing by the measurement wheel of beam-end.
