Description
Technical field
The utility model relates to urban track traffic, particularly a kind of modern tram groove-shape rail spacing device.
Background technology
Modern tram system is the novel rapid transit system growing up on traditional tram basis, and compared with motor bus, its freight volume is large, speed fast, it is little, comfortable to pollute, safety, longer service life; Compared with subway, its construction investment is economized, and construction speed is fast, and running cost is low, easy to maintenance.Therefore, modern tram system is the important embodiment of " harmonious traffic " and " benefit traffic ", for improve urban traffic environment, alleviate urban traffic pressure, promote city image significant.In recent years, modern tram in Dalian, the city such as Shenyang, Tianjin, Suzhou adopts gradually, and is also rapidly developed and promotes in other city.
Modern streetcar track adopts buried grooved rail structure, according to the functional requirement of different sections, adopts the forms such as lawn, pitch and footpath ground tile to lay; The vehicle of tram adopts mechanism of independent wheel to structure simultaneously, and track lateral force is increased.Therefore, there is difference in the track demand of modern tram and existing railway or underground railway track, the requirement that original track component can not the modern tram of fine adaptation.
Street railway is walked in urban road, and route curve radius is very little conventionally, and minimum may reach 30m, and circuit maximum gradient may reach 60 ‰.Conventionally tram groove-shape rail adopts welding point to form gapless track, can reduce vehicular impact and running noises.But under small radius and heavy grade condition, CWR Track Stability is poor, need takes to increase the spacing devices such as tie rod and add stiff stability.Because of the tram groove-shape rail flange of rail and railway roadbed gap little, existing tie rod can not be installed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of modern tram groove-shape rail spacing device, so that the maintenance of the gauge of two groove-shape rails is constant, forms section of track framework, guarantees the stability of gapless track.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Modern tram groove-shape rail spacing device of the present utility model, it is characterized in that: it comprises left side pull bar, right side pull bar and intermediate sleeve, the inner of left side pull bar, right side pull bar forms coaxial being threaded with intermediate sleeve respectively by reverse screw thread, outer end, through the insulation sleeve being installed in groove-shape rail vertical section through hole, arranges respectively locking nut, adjusting nut on left side pull bar, right side pull bar outside insulation sleeve outer end and the inner.
The beneficial effects of the utility model are can make the gauge of two groove-shape rails keep constant, formation section of track framework, the stability of assurance gapless track; Simple in structure, installation, easy to adjust.
Accompanying drawing explanation
This manual comprises following three width accompanying drawings:
Fig. 1 is the structural representation of the modern tram groove-shape rail of the utility model spacing device;
Fig. 2 is the enlarged diagram of A part in Fig. 1;
Fig. 3 is the structural representation of the modern tram groove-shape rail of the utility model spacing device insulation tube.
Component shown in figure, toponym and corresponding mark: groove-shape rail 10, left side are concrete road bed 11, right side is concrete road bed 12, intermediate sleeve 20, left side pull bar 21a, right side pull bar 21b, locking nut 23, adjusting nut 23, insulation tube 30, flange 31.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See figures.1.and.2, modern tram groove-shape rail spacing device of the present utility model comprises left side pull bar 21a, right side pull bar 21b and intermediate sleeve 20, the inner of left side pull bar 21a, right side pull bar 21b forms coaxial being threaded with intermediate sleeve 20 respectively by reverse screw thread, outer end is through the insulation sleeve being installed in groove-shape rail 10 vertical section through holes, and left side pull bar 21a, right side pull bar 21b are upper arranges respectively locking nut 23, adjusting nut 23 outside insulation sleeve outer end and the inner.Groove-shape rail 10 is fixedly mounted on that left side is concrete road bed 11, the top on right side concrete road bed 12.By the adjusting nut 23 buffer rail distance easily on left side pull bar 21a, right side pull bar 21b, lock after the locking nut 23 of two, can make the gauge of two groove-shape rails keep constant, form section of track framework, guarantee the stability of gapless track.
With reference to Fig. 2 and Fig. 3, the effect of insulation sleeve is between the groove-shape rail of the left and right sides, to form insulation, can meet the demands such as track circuit or signal transmission.For ease of installing, insulation sleeve consists of two opposing insulation tubes 30, and one end of insulation tube 30 has the flange 31 that extends radially outwardly and form.
Some principles of the above the modern tram groove-shape rail of the utility model spacing device that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
Claims (2)
1. modern tram groove-shape rail spacing device, it is characterized in that: it comprises left side pull bar (21a), right side pull bar (21b) and intermediate sleeve (20), the inner of left side pull bar (21a), right side pull bar (21b) forms coaxial being threaded with intermediate sleeve (20) respectively by reverse screw thread, outer end is through the insulation sleeve being installed in groove-shape rail (10) vertical section through hole, and left side pull bar (21a), right side pull bar (21b) above arrange respectively locking nut (23), adjusting nut (23) outside insulation sleeve outer end and the inner.
