Abstract
The utility model relates to measuring instruments and aims at providing an abrasion gauge for railway track combination frogs. The gauge comprises a ruler provided with length measuring graduations. One end of the ruler is provided with a fixed supporting seat, and the other side of the ruler is provided with a moving supporting seat capable of sliding. A vernier is arranged on the ruler and between the fixed supporting seat and the moving supporting seat. An indication rod capable of moving vertically is arranged on the vernier. The bottom of the indication rod is provided with a tip. The gauge is reasonable in design, simple in structure, convenient to process, and applied to measuring of abrasion of various combination frog rail wings and point rails, and can better ensure traffic safety.
Description
Technical field
The utility model relates to measuring apparatus, in particular, relates to a kind of railroad track assembled frog and uses abrasion measuring instrument.
Background technology
The assembled frog that present railway track frog generally uses owing to rolled repeatedly by wheel, causes wing rail, the common stressed triangle abrasion of heart rail district serious wear, directly influences the ride comfort of traffic safety and track.For guaranteeing traffic safety, after wearing and tearing to a certain degree, railway standard regulation wing rail or heart rail must change.But because the restriction of the shape of wing rail and heart rail, space, relative position, existing measurer is difficult to accurately measure its wear intensity.
For solving the measurement of wear problem of assembled frog wing rail and heart rail, design a kind of railroad track assembled frog at present and solve existing problems with abrasion measuring instrument.
The utility model content
The technical problem that the utility model will solve is, overcomes deficiency of the prior art, and a kind of instrument that can quick and precisely measure assembled frog wing rail and heart rail abrasion loss is provided, and guarantees traffic safety.
In order to overcome the above problems, the utility model is realized through following technical scheme.
Provide a kind of railroad track assembled frog to use abrasion measuring instrument, comprise the ruler of strip length metering scale; End at ruler is provided with fixed bearing, and the ruler opposite side is provided with the bearing that moves about that can slide; On the ruler between two bearings, be provided with a walk scale; On walk scale, be provided with the indicating arm that can vertically move, its bottom has a tip.
The bearing that moves about can move at the ruler length direction, to adapt to the change width between railway frog different parts two wing rails.Altitude scale is vertical and moving up and down with the ruler length direction, is convenient to measure the abrasion loss of wing rail or heart rail.
As a kind of improvement, the said indicating arm that can vertically move is the altitude scale with length metering scale, and on walk scale, is provided with corresponding gauge position sign.
As a kind of improvement, said fixed bearing is fixedly installed on the ruler by the mode of bolt assembly or welding.
As a kind of improvement, said fixed bearing all has the shape of mating with the rail head of rail profile phase with two the relative inboards of bearing of moving about.Said two bearings also can be designed to different section configurations, to adapt to the railway frog of different rail kinds.
Compared with prior art, the beneficial effect of the utility model is:
The measurement of wear that the novel railway track assembled frog that the utility model provides is reasonable in design, simple in structure, easy to process with abrasion measuring instrument, can adapt to various assembled frog wing rails and heart rail guarantees traffic safety better.
Description of drawings
Fig. 1 is that the utility model railroad track assembled frog is used the abrasion measuring instrument overall schematic.
Fig. 2, Fig. 3 are that the utility model railroad track assembled frog is with abrasion measuring instrument metering system sketch map.
Reference numeral is: 1 ruler, 2 fixed bearings, 3 move about bearing, 4 walk scales, 5 altitude scales, 6 wing rails, 7 heart rails.
The specific embodiment
In conjunction with accompanying drawing, be elaborated in the face of the utility model down.
Novel railway track assembled frog among the embodiment is used abrasion measuring instrument, comprises ruler 1, fixed bearing 2, the bearing 3 that moves about, walk scale 4 and altitude scale 5.Fixed bearing 2 is fixed in ruler 1 one ends, and realizes fixed installation by modes such as bolt assembly or welding, and the initial position standard of walk scale 4 is provided.The bearing 3 that moves about can move at ruler 1 length direction, to adapt to the different in width between railway frog different parts two wing rails 6.Walk scale 4 between two bearings, on the moving up and down altitude scale 5 vertical with ruler 1 length direction arranged, be convenient to measure the abrasion loss of wing rail 6 or heart rail 7.
When measuring, the fixed bearing 2 and the bearing 3 that moves about are supported on the railway frog both sides wing rail 6, and the inner edge of fixed bearing just is positioned at the rail head of rail mid point.Because the structural limitations of railway frog, the abrasion of wing rail 6 and heart rail 7 all between two bearings, so only need move walk scale 4, then can be measured the abrasion value of wing rail 6 and heart rail 7 different parts.When walk scale 4 was close to fixed bearing 2, walk scale was a zero graduation, and when simultaneous altitude scale and wing rail 6 rail heads joined, scale was zero.Moving the point that walk scale 4 to needs are measured, altitude scale 5 tips are joined with the railway frog survey mark, draw height value, deduct the original height value again, then is the abrasion value of wing rail 6 or heart rail 7.
Bearing can be designed to different section configurations, to adapt to the section configuration of different rail kind railway frogs.
At last, it should be noted that above what enumerate is the specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought the protection domain of the utility model.
