This nose movable crossing extends several meters to the crossing position from the front to arrange the wing rail, movable nose rail and crossing structure from the front of the existing wing rail and nose rail. In some cases, it is impossible to carry out depending on the terrain, and the structure itself is complicated, which is difficult to manufacture, expensive, and low in durability.

On the other hand, a so-called wing movable crossing in which a wing rail is movable as shown in FIG. 15 is known, and this can solve the inconvenience of extending the rear end of the branching device as described above. This lays a movable wing rail 20 and a fixed wing rail 21 forward from the vicinity of the nose end 19 of the nose rail 1, and a rear end portion 24 of the fixed wing rail 21 is bolted to the nose rail 1 via a spacing member 70. The front part 25 of the movable wing rail 20 is fastened to the frame member 71 by bolts and nuts, and the front part 23 of the movable wing rail 20 is bent to the space member 71 through a joint plate 72 to form a smooth joint, that is, At the time of conversion, the front portion 23 of the movable wing rail 20 or the curved joint plate 72 and the spacing member 71 are connected so as to slide and rotate, and further, the rear end portion 28 of the movable wing rail 20 is connected to the long nose rail 10.
The spring device 4 and the supporting devices 40, 40 are attached to the outer surface of the movable wing rail 20.

When the vehicle travels on the high speed side H, the solid line wheels 9 advance as shown by the solid line arrows, while on the other hand, the vehicle running on the low speed side L has the chain line wheels 90 facing backward from the rear. The vehicle travels and pushes open the movable wing rail 20 in the direction indicated by the alternate long and short dash line by the flange 91 itself of the wheel 90 to pass therethrough. The movable wing rail 20 returns to its original position by the spring device 4 after the vehicle has passed.

[0005]

According to the above-mentioned wing movable crossing, the vehicle traveling on the low speed side L can only travel one way from the rear to the front and cannot travel from the front to the rear to reach a specific location. It is limited to the use of. Further, when the movable wing rail 20 is opened and closed, the front portion 23 slides and rotates, and the joint 26 at the front end moves, so that it is necessary to form a clearance d between the movable wing rail 20 and the front rail 7. The seam 26 cannot avoid the impact of the traveling vehicle.

[0006]

The present invention eliminates these disadvantages and has other effects, that is, a pair of wing rails are laid from the vicinity of the nose end of the nose rail toward the front. In the crossing in which guard rails are juxtaposed close to the main rail, at least one of the pair of wing rails is a movable wing rail, and the movable wing rail has an elastic portion formed in the middle and a front portion of the movable wing rail. The movable wing rail is fixed, and the movable wing rail is provided so as to be convertible by a rolling rod, and the movable wing rail and the guard rail are both placed on a through floor plate.
