Description

[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel guide device at a railroad crossing end.

[Prior art]

At railroad crossings, lay plates and blocks such as blocks at the same height as the rail surface so that people and automobiles can pass safely and smoothly, and also install wheel flanges on the inner side of the rails so as not to interfere with train travel. A flangeway is provided to allow passage. In addition, when the train passes the railroad crossing, it prevents the wheels from climbing onto the floor boards or blocks and derailing, or when the train derails before the railroad crossing, the wheels are returned to the main rail, It is obligatory to form a wheel guide part for guiding the wheel flange part to the flange way. Therefore, conventionally, as shown in FIG. 5, the guard rail 2 is laid on the inner rail side of the main rail 1 so that both ends project from the railroad crossing end, and the flange way 3 is secured,
The protruding end is bent to the inner rail side to form the wheel guide portion 4. In the figure, reference numeral 5 is an inner plate laid between the guard rails 2 and 2, and 6 is an outer plate laid outside the main rail 1.

[Problems to be solved by the device]

However, in order to lay a guardrail as in the conventional case, the sleeper must be provided with a fastening device for fastening the guardrail in addition to the main rail fastening device, and a concrete sleeper is difficult to design and expensive. There is a problem. In addition, during track maintenance work such as compacting the roadbed, it takes time and time to remove and restore the guardrail, which not only significantly lowers work efficiency, but also may damage the fastening device by the work. is there. Therefore, the present invention has been made in view of the above-mentioned conventional problems, and the railroad crossing itself has a structure in which a flange way can be secured without using a guardrail, so that mounting and dismounting are easy, and further, An object of the present invention is to provide a wheel guide device that can be reliably and easily installed at a predetermined position and does not slide after installation, and solve the above-mentioned conventional problems.

[Means for solving problems]

Therefore, according to the present invention, the wheel guide device includes a pair of left and right short guide members whose tip ends are bent in the direction of the center of the track, leaving the base, and a fastening member that is fixed to the lower surface of the guide member and attaches the guide member to the main rail. And a connecting member for connecting the left and right guide members via a mounting plate fixed to the inner rail side of the guide member, and at the predetermined position corresponding to the main rail of the fastening plate, By having a structure in which a positioning fitting projection to be fitted to the hem is provided in a projecting manner, the intended purpose is achieved.

[Action]

First, a method of attaching the wheel guide device to the track of the railroad crossing end will be described. In advance, the fastening plates are fixed to the lower surface of the guide member near the front and rear ends by welding, and the mounting plates are fixed to the inner side of the guide member near the front and rear ends by welding. Then, the base side of the guide member is arranged so as to abut against the end surface of the inner plate of the railroad crossing end, and the fitting protrusion protruding from the guide member is fitted to the hem of the main rail for positioning. After that, fasten with fastening bolts. Next, a connecting member is interposed between the left and right guide members and fixed to the mounting plate with bolts and nuts to connect the left and right guide members. After that, on the roadbed on the front side of the front connecting member, the anti-slip pile is driven upright so as to be in contact with the front surface of the connecting member. As a result, when the flange of the wheel of the train enters the railroad crossing, even if the rail derails before the railroad crossing, the guide member guides the flange of the wheel to the flange way, and the wheel rides on the main rail and crosses the railroad crossing. Can pass normally.

【Example】

Hereinafter, the present invention will be described according to illustrated embodiments. Reference numeral A is a wheel guide device, and a pair of left and right guide members 1
1, a fastening plate 12, a mounting plate 13, a connecting member 14 and the like. The guide member 11 is made of short channel steel bent in a substantially L-shaped cross section, and is formed by bending the tip 11b side toward the center of the track, leaving the base 11a. Further, a notch 11c is formed on the side wall of the base 11a of the guide member 11 for fitting the fitting projection 16 and the end of the clip 32 which will be described later. Reference numeral 27 is a reinforcing plate provided in the base portion 11a of the guide member 11. Further, the fastening plate 12 is formed by cutting a grooved steel into a predetermined length so as to be fixed near the lower front and rear ends of the guide member 11, and one side in the longitudinal direction with the horizontal surface as the upper surface is the main line. The other side of the horizontal surface is fixed to the lower part of the rail B near the front and rear ends of the lower surface of the guide member 11. A predetermined position of the fastening plate 12 corresponding to the main rail B, that is, a flange way 26 described later between the base 11a of the guide member 11 and the main rail B when the fastening plate 12 is fastened to the main rail B. Fitting projections 16, 16, ... Which are fitted to the skirts 31a, 31b of the main rail B are projected at positions where the gap 15 is formed. Reference numeral 17 is a locking projection that locks a clip 32 that serves as a rail retainer, and 33 is a fastening bolt. The connecting member 14 is formed of wood or the like having an insulating property, and a bolt 18 and a nut 19 are attached to a mounting plate 13 fixed by welding on the inner rail side of the guide member 11 near the fastening plate 12 fixed thereto.
It is fixed by and the left and right guide members 11 are connected. Reference numeral 20 denotes a slide stop pile that prevents the wheel guide device A from sliding, and is erected on the road bed 21 on the front end side of the connecting member 14 on the front side of the wheel guide device A. Reference numeral 22 denotes a non-slip plate for preventing sliding of the outer plate 23 of the railroad crossing, which is attached to the upper surface of the outer end of the fastening plate 12 by a mounting bolt 24. The anti-slip plate 22 also has a clip locking projection. Also serves as. Reference numeral 25 denotes an inner plate laid between the main rails B, and flange ways 26 are formed at both ends of the inner plate 25. The guide member 11 prevents the inner plate 21 from sliding.

[Effect of device]

As described above, according to the present invention, a pair of left and right short guide members whose distal end is bent toward the center of the track, leaving the base portion, and a fastening member that is fixed to the lower surface of the guide member and that attaches the guide member to the main rail. Since the plate and the connecting member that connects the left and right guide members via the mounting plate fixed to the inner rail side of the guide member are used, mounting and removal can be performed very easily. Therefore, it is possible to improve the work efficiency of the track maintenance work such as compacting the roadbed near the railroad crossing end. Further, according to the present invention, since the positioning fitting projections to be fitted to the hem of the main rail are projected at predetermined positions corresponding to the main rail of the fastening plate, the positioning of the guide member can be performed very easily. In addition to being exposed, it does not slide due to running vibration of the train, etc., so that the gap between the guide member base and the main rail can always be kept normal. Therefore, since there is no rubbing between the gap and the flange way, the running of the train is not hindered. Further, according to the present invention, since it is not necessary to make a work for fastening the wheel guide device to the sleeper, it is possible to use a concrete sleeper having a good train running property also at the railroad crossing end. Further, according to the present invention, since the short channel steel bent in the substantially L-shaped cross section is used for the guide member, it is possible to easily form the rail compared with the short rail. Is to have.
