Abstract
The present invention relates to a kind of fixed end frog wing rail, be made up of wing rail and guard rail, central body of frog both sides arrange, rail wing and guard rail apical side height from the guard rail starting point place of corresponding central body of frog to guard rail stage casing, lower than rail type calibrated altitude frog rail end face.The invention has the beneficial effects as follows, by reducing the wing rail and guard rail apical side height that form " wedge angle " region, avoid new this position of upper track railway frog contact with wheel end prematurely and too fast even flake-off block phenomenon occurs to wear away, improve the application life of railway frog, slowing down wheel that the false wheel rim of wheel when forward going out to pitch causes to raising phenomenon simultaneously, improving train operation stationarity.
Description
Technical field
The present invention relates to a kind of fixed end frog of rail track track switch, belong to the technical field of improvement of railway track.
Background technology
The connection that track switch being makes rolling stock realize entering or cross another circuit by a circuit with intersect equipment.Railway frog is the key equipment that rail track realizes train crossing operation, is to make wheel cross the equipment of another strand of rail by one rail.For ensureing the smooth-going stable operation of train wheel in existing track switch design, require that flange tread remains on sustained height.Namely in effective contact range of wheel, the flange tread of railway frog and heart rail, wing rail apical side height are all consistent.But train is by wheel track when rail, frog surface run, and the traveling situation that new and old wheel is formed is not quite similar, therefore from the complete matching that cannot realize wheel track and track switch interaction face actual behavior in service.New wheel operation a period of time or by certain load-carrying after, the abrasion of end are much smaller than wheel rim side, time like this near train operation to central body of frog 40 ~ 50mm section, the railway frog of new upper track just there will be wing rail working edge and contacts with wheel and form sharp bladed bright band phenomenon too early, be i.e. " wedge angle " condition regions.Under constantly impacting in train travelling process, wearing away,, because loaded area is narrow and small, easily there is flake-off block phenomenon too early in the corner region that this region wing rail work avris is formed, strengthen the maintenance workload of works department, even directly affect the application life of railway frog.
Summary of the invention
Serious until there is flake-off block phenomenon too early for slowing down wing rail abrasion near new upper track central body of frog 40 ~ 50 section, the invention provides a kind of fixed end frog wing rail of improvement, to slow down end face, flake-off block phenomenon occurs by the wing rail and guard rail height reducing above-mentioned zone and train wheel rear end contact portion too early.
The present invention's adopted technical scheme that solves the problem is: this fixed end frog wing rail, be made up of wing rail and guard rail, arrange in central body of frog both sides, rail wing and guard rail apical side height from the guard rail starting point place of corresponding central body of frog to guard rail stage casing, lower than rail type calibrated altitude frog rail end face.
Described fixed end frog wing rail apical side height Gradient Descent from the guard rail starting point place of corresponding heart rail, the middle reduction flat segments through one section of 3 ~ 5mm, then gradient rises to the standard gauge height of the reduction terminal in guard rail stage casing.
Described fixed end frog wing rail apical side height reduces the inverted trapezoidal that broken line is two ends inclination neutral straight.
The guard rail starting point of described fixed end frog wing rail is that corresponding heart rail width 40-50mm cross-section reduces starting point as wing rail and guard rail apical side height.
Described fixed end frog wing rail, described wing rail and guard rail end face, from reduction starting point, reduce by 3 ~ 5mm along guard rail direction 100 ~ 200mm scope, keep 300 ~ 500mm scope flat segments, then 200mm scope rise to the standard gauge high altitude reducing terminal.
The invention has the beneficial effects as follows, by reducing the wing rail and guard rail apical side height that form " wedge angle " region, avoiding new this position of upper track railway frog and contact with wheel end prematurely and too fast even flake-off block phenomenon occurs to wear away, improve the application life of railway frog.Slowing down wheel that the false wheel rim of wheel when forward going out to pitch causes to raising phenomenon simultaneously, improving train operation stationarity.
Accompanying drawing explanation
Fig. 1 is railway frog schematic top plan view,
Fig. 2 is the A direction view of Fig. 1.
In figure: 1, wing rail; 2, guard rail; 3, starting point is reduced; 4, there is " wedge angle " condition regions; 5, central body of frog (width 40-50mm cross section); 6, starting point is reduced to flat segments region; 7, flat segments is reduced; 8, flat segments is to reducing land; 9, railway frog standard gauge type height; 10, terminal is reduced; 11, existingly tread face is shielded with one's own body; 12, rear wing guard rail end face is improved;
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described, as shown in Figure 1, fixed end frog wing rail of the present invention, be made up of wing rail 1 and guard rail 2, arrange in central body of frog 5 both sides, in order to overcome the adverse effect that 4 pairs, generation " wedge angle " condition regions rail wing end face causes, present invention reduces the rail wing 1 in this region and the apical side height of guard rail 2.Concrete apical side height to reduce from the guard rail starting point place 3 of corresponding central body of frog 5 to guard rail stage casing reduces terminal 10.
The present invention's corresponding heart rail width 40mm cross-section reduces starting point 3 place as the guard rail starting point of railway frog and wing rail guard rail apical side height, reduces 3-5mm, as Fig. 2 reduces shown in starting point to flat segments region 6 along guard rail 2 direction 100 ~ 200mm scope inside gradient; Then keep 3-5mm guard rail end face to reduce along guard rail direction 500mm length range, form guard rail and reduce flat segments 7; Being increased to railway frog standard gauge type height 9 to reducing terminal 10 gradient within the scope of 200mm backward again, being formed and reducing flat segments to reducing land 8, as shown in Figure 2.
Wing rail guard rail top surface shape after the present invention improves effectively can reduce generation " wedge angle " condition regions 4 and the adverse effect that " wedge angle " cause railway frog end face occurs, avoid new upper track railway frog contact with wheel end prematurely at this position and flake-off block phenomenon occurs, thus improve the application life of railway frog; Slowing down wheel that the false wheel rim of wheel when forward going out to pitch causes to raising phenomenon simultaneously, improving train operation stationarity.
