Description

Description: TECHNICAL FIELD The present invention relates to a railway crossing at an intersection between a railway and a road.

(Prior Art) Railroad crossings are important facilities in traffic where railways and roads intersect, and it is desired that the railroad crossings be structurally robust, have no breakdown, and be easily maintained. Under such circumstances, a railway crossing (hereinafter referred to as "A invention") described in JP-A-1-198906 has been developed.

The railroad crossing according to the invention A, as shown in FIG. 22, is provided with a plurality of sets of support plate fastenings 5a to 5h at set intervals in the longitudinal direction of the iron sleeper 2, and furthermore, The edges of the open-sided side plates of the groove-shaped prone bearing plates 6a to 6e are elastically fitted into the locking grooves of the bearing plate fixing fittings 5a to 5h.

7a to 7e in the figure are grooved prone support plates 6a to 6e and rails 4a, 4
In this example, a deformed steel is used as a reinforcing material that narrows the gap with the b and the like to eliminate obstruction of traffic and protects the groove-shaped prone support plates 6a to 6e. The reinforcing members 7a to 7e are mounted on the side surfaces of the grooved prone bearing plates 6a to 6e facing the rail at substantially the same height as the grooved prone bearing plates 6a to 6e.
Further, 8a and 8b are asphalt fillers, and the cross-sectional grooved prone bearings 6a to 6e have substantially the same height as the grooved prone bearings 6a to 6e.
Filled in between.

Since the railroad crossing of the invention A has the above-described configuration, the upper surfaces of the grooved cross-section supporting bearings 6a to 6e fixed to the iron sleepers 2 are polished and worn by tires of vehicles passing through the railroad crossing, and It becomes easy to slip. In addition, asphalt fillers 8a and 8b
Since the cross section is V-shaped as shown in FIG. 2, it is easily peeled off by a tire of a vehicle passing through a railroad crossing.

Therefore, when the asphalt fillers 8a and 8b are peeled off, the vehicle passing through the level crossing of the invention A travels on an uneven and slippery road surface, and the tires may slip and the steering wheel may be removed. Had serious safety issues. In addition, since the asphalt fillers 8a and 8b are filled and repaired every time a concave is formed, there is a problem that maintenance cost is high.

Further, since the grooved cross-section supporting bearings 6a to 6e are made of a corrosion-resistant material in order to prevent their wear from being increased by corrosion, the railway crossing according to the invention A becomes expensive. there were.

(Problems to be solved by the invention) In view of the above circumstances, the present invention improves the above-mentioned A invention,
An object of the present invention is to provide a railroad crossing that has high safety and low maintenance and construction costs by making the upper surface of the railroad crossing difficult to slide and by preventing the treads from loosening.

(Means for Solving the Problems) The present invention provides a rail fastener for fastening a pair of rails, and a bearing plate for fastening a grooved prone stopper to the inside and both outsides of the pair of rails. A pair of rails are removably fastened to a plurality of iron sleepers having a fastening fitting fixed to the upper surface via these rail fastening fittings, and the groove cross-section is detachably attached to each of the inner side and both outer sides. The proboscis stop was fastened and the central tread was superimposed on the grooved prosthesis in the inside, and it was superimposed on the crosses prone in the outer sides. A bent front end portion of a plurality of pressing and holding band fittings which are provided at predetermined intervals at or near the track-side end or the end of the center tread and the end tread with a grooved prone tread having an end tread. Railroad crossing characterized by being elastically pressed and clamped to a rail fastening by a clip through a rail I will provide a.

Further, in the railroad crossing described above, the cross-sectional groove-shaped bucking support plate located on the outermost side of the iron sleeper has a lower paragraph groove, and is provided at an end or near an end of the end tread plate opposite to the rail side. A railroad crossing characterized in that a plurality of bent edges of the outer edges vertically provided at intervals of (f) fit into and engage with the lower paragraph groove.

(Operation) As shown in FIGS. 2, 3, and 4, the railroad crossing according to the present invention fixes the rail fastener and the support plate fastener fixed to the upper surface of the iron sleeper. A rail is removably fastened to the iron sleeper via a track fastening fitting, and a groove-shaped cross-section bearing supporter is removably fastened to the iron sleeper between the supporter fastening fittings, and On the upper surface of the grooved prone stop board, a grooved prone tread plate made of striped steel plate or the like is superimposed and placed, and pressing and holding band metal fittings are vertically suspended at predetermined intervals near the rail side end of the grooved prone tread plate. The bent front end provided near the lower end of the pressing and holding band fitting is elastically pressed with a clip on the upper surface of the rail fastening fitting and held. In addition, the clip presses not only the pressing and holding band fitting but also the rail at the same time to hold the clip.

The cross-sectional groove-shaped protruding plate has a plurality of pressing and holding band members hanging at predetermined intervals in the vicinity of an end thereof, and a lower bent portion near a lower end of the pressing and holding band metal fitting has a rail fastening member of a clip. Is firmly fixed because it is pressed by the clip fastening the rail to the iron sleeper.

By the way, as is well known, a heavy-weight train runs at a high speed, so that when a train passes a railroad crossing, the railroad crossing vibrates in a state where the iron sleeper presses down on the ballast ballast and sinks. For this reason, since the cross-sectional grooved prone stop board is fixed to the iron sleeper, the vibration of the iron sleeper is applied to the cross-section grooved prone board which is superimposed via the cross-sectional grooved prone stop board. Also propagates.

However, in the railroad crossing of the present invention, since the pressing and holding band metal fittings of the above-mentioned grooved prone tread are fastened with the same force as the rail, the cross-sectional grooved prone tread is also affected by the vibration of the train. I do not loosen. Therefore, the railway crossing of the present invention is safe.

Further, since the cross-sectional grooved prone tread is fixed via a clip, the detachment of the clip makes it possible to remove the cross-sectional grooved prone tread. is there.

However, when fastening the above-mentioned grooved prone step board,
In the prior art, bolt fastening is adopted, but the bolt is easily loosened by vibration, and if the bolt is loosened, the cross-sectional grooved prone footboard is displaced, and the train wheel is displaced. Railroad crossings were rarely used on railroad tracks using iron sleepers because they could cause derailment accidents when they got on the treads.

Further, there is a problem that the bolt is liable to be removed due to adhesion of dirt or rust to the bolt or a screw portion is crushed, and thus there is also a problem that maintenance is difficult at a railway crossing. Due to these circumstances, railroad crossings were not widely used.

The railroad crossing of the present invention uses a clip that fastens the rails, and embodied a method of fastening the grooved prone tread to an iron sleeper. It was not loose, it was safe and easy to maintain.

In a conventional railroad crossing, the use of clips that fasten rails has never been considered before.

The railroad crossing of the present invention, because the reaction force of the clip that fastens the rail to the iron sleeper is directly diverted, the groove cross-section prone treads will not be slackened by the vibration of the train or vehicle at the crossing, It is extremely safe and easy to maintain.

In addition, since one side edge or both side edges of the grooved prone step board is configured to bend downward, there is no risk of tripping when a vehicle runs or a pedestrian passes.

Next, in the case of using a grooved prone step board composed of a center tread and an end tread on a grooved prone stop board,
The groove-shaped prone center tread has a plurality of pressing and holding band fittings and a rail having a holding bent front end portion on both side edges or near the inner side of the lower bending, and the rail is elastically pressed and held via a rail fastening fitting. Therefore, the holding can be performed reliably and robustly as described above.

Further, the cross-sectional grooved prone stepboard has a bent portion at the outer edge tip portion which can be fitted and locked to the support plate fixing fitting, so that the bending groove is formed in the fitting groove of the support plate fixing fitting. Can be easily fitted and fastened simply by inserting the next, and a plurality of folding pressure holding band fittings having a holding bent front end portion are provided at predetermined intervals in the vicinity of the lower inside edge or inside the inner edge of the groove-shaped prone end tread plate. It is configured in the same manner as the central tread plate so as to be vertically installed, and the pressing and holding band metal fitting and the rail can be elastically pressed and held together via the rail fastening metal fitting. By pressing and holding the inner edge of the lower bend, the holding thereof can be carried out reliably and robustly, similarly to the central tread.

Next, the cross-sectional grooved prone retaining plate is composed of a prone groove shaped steel in which the edges of both side plates that open outward in the retaining groove of the retaining plate fixing fitting are elastically fittable. It is possible to easily resiliently insert or remove it from the fastening plate fastener by a simple operation of sandwiching the both sides with. For this reason, there is an advantage that the groove-shaped prone retaining plate can be repaired and replaced in a very short time.

If it is welded and fixed between the pressing and holding band metal fitting and the tread plate and the inner side edge of the lower bend and between the pressing and holding band metal fitting and the back surface of the tread plate, if it is welded and fixed, through the lower bending preventing reinforcing plate Since it is possible to transmit the pressing force from the upper portion to, for example, the bearing plate fastener, it is possible to reduce the damage such as breakage and bending, and the damage due to vibration and repeated load is extremely reduced. .
