The cross section of a steel track of the track detection device is in a U shape, the entire vertical view is in a H type, the inner sides of the U-shaped steel track are provided with protective wings for limiting wheel edges; the outer sides of the U-shaped steel track are provided with bearing wings for bearing wheels; and the protective wings at the two sides are connected to form an integral structure by the bottom. The utility model has reasonable structure, is easily installed and maintained, has good environmental adaptability, high safety and reliability and long service life.
Description
Technical field
The utility model relates to a kind of non-destructive detection device, refers to the on-line measuring device to railway wheel especially.
Background technology
Train wheel is one of vitals that ensures train operating safety.Along with train develops towards high speed, heavy duty, long routing,, more apparent urgent to the detection and the guarantee of wheel.At external technical scheme and case history, actual conditions in conjunction with China, patent 200520118146.2 discloses a kind of practical scheme, but in reality is tentative, find that following typical case is not enough: 1, common rail, inclined to one side outward by twist distortion, limited by structure and material, the pole of orbit is easy to wear, must switch tracks every year, and northern area even possibly can't adopt; 2, in the slit of track and guard rail, the transducer inconvenience is safeguarded in Installation and Debugging, is difficult for realizing standardization of technology, the conformability of can not ensuring the quality of products, and the industrialized implementation difficulty is big.
Summary of the invention
The purpose of this utility model is:
Design a kind of standardized online detection rail set
Main technical schemes of the present utility model is:
Make one section special rail of U-H type, the rail section is the U type, and whole plan view is the H type.The inboard of U shaped steel rail is a flap, the restriction wheel rim; The outside of U shaped steel rail is the load-bearing wing, the carrying wheel.The middle bottom of U shaped steel rail is processed with groove, and groove is mainly used in lays electric wiring, coupling liquid pipeline and water back.The middle bottom of U shaped steel rail, overall leveling is used for installation and measuring probe and linear transducer array.The two ends of the load-bearing wing are connected with straight transition is arranged between the common rail.Above-mentioned U-H shaped steel rail, specific aim design, integrated molding.A whole set of detecting device generally comprises: two on above-mentioned special U-H shaped steel rail, the linear transducer array of installing in the U shaped steel rail, detection control path, coupling liquid pipeline, water back, multi-channel detection instrument and background computer.The continuous linear transducer array that is used to test, its total length is greater than the wheel circumference of existing maximum specification.Before tested wheel enters tested zone, be mounted with pre-spray equipment; Wheel is tested the speed in real time, test enable signals is provided during for intensive test; When wheel enters test zone, put, to wheel automatic-spraying mark corresponding to the first location of test probe.Coupling liquid pipeline to outdoor has heat insulation and heating equipment.Coupling liquid after reclaiming, purifying, repeated usage.Man-computer interface emulationization can directly observe the right hurt type of measured wheel and the particular location of defective.
On year-on-year basis, the utility model has the advantages that:
1) special U-H shaped steel rail, the common rail of straight butt joint overcomes uncertain potential safety hazards such as deformational stress, and safety is secure;
2) special rail, at purposes and Environment Design, integrated construction is convenient to the installation and maintenance management, is convenient to normalisation, industrialization.
3) special rail is convenient to adopt the structure that meets mechanics and is adopted high-abrasive material such as manganese steel, improves reliability greatly, increases the life-span, reduces and safeguard use cost;
4) between the U shaped steel rail both wings, bigger space is arranged, be convenient to settle more linear transducer array, avoid omission.
Description of drawings
Fig. 1 is an agent structure scheme drawing of the present utility model.
Fig. 2 is the utility model generalized section.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
Fig. 1 is rail and probe segment agent structure schematic top plan view, 1,1 '-coupling liquid is sprayed in advance and is triggered probe, 2,3,2 ', 3 '-holes probe, 4,4 '-spraying mark triggers device, the common rail of 5-, the straight blank area of 6-rail, 7-U-H shaped steel rail flap, the heavy wing of 8-U-H shaped steel rail bearing, 9-U-H shaped steel rail pipe-line tank, the 11-measured wheel is right.All kinds of probes can symmetric arrangement, and the forward and reverse rolling of train wheel can both corresponding test, in case of necessity, by leapfrog test, is used for reinspection.
Fig. 2 is the A-A cutaway view, and the 10-rail is installed the bottom, and 12-pops one's head in (array), and 9-1 is the coupling liquid pipeline, and 9-2,9-3 are the heat tracing pipelines, and 9-4 is detection signal and control cable groove.All the other labels and last same.
Testing process is: wheel triggers sensor 1, and spray starts in advance, wheel is cleaned and infiltration coupling effect when improving test; Then, by the time of successively triggering sensor 2,3, computing machine calculates the speed of wheel walking automatically, for the test of linear transducer array provides sampling control or revises reference; Trigger sensor 4, spray mark automatically, beginning cooresponding test of linear transducer array and sampling.Sampled result transmits background computer and focuses on after instrument is collected conversion, and the test result of intuitive display.
Claims (4)
1, the online detection rail set of a kind of integrated railway wheel, it is characterized in that: the rail section is the U type, and whole plan view is the H type, the inboard of U shaped steel rail is a flap, the restriction wheel rim, and the outside of U shaped steel rail is the load-bearing wing, the carrying wheel, two side flaps are by bottom linking into an integrated entity structure.
