Description

[Detailed description of the invention] The present invention relates to a running wheel with a movable flange, and more specifically, a running wheel with a movable flange for a rail transporter that transports rails and track maintenance equipment using one line of a railway track, a handcart, etc. It is related to.

In general, double-flange type wheels are used for rail carriers and other vehicles that transport rails on one track of railway tracks to avoid the risk of derailment. If both flanges of the running wheel are fixed, the running wheel cannot pass, so one flange rides on the rail surface when passing a point. Conventionally, this type of running wheel is The movable flange is supported by a plurality of springs on the other side of the wheel body on which the flange is formed.

However, since the movable flange is supported by a plurality of springs, the movable flange cannot move smoothly when passing a point, and there is a risk of derailment.

There is also the problem that assembly is time consuming.

The present invention was made in view of the above circumstances, and its purpose is to provide a traveling wheel with a movable flange that allows the movable flange to be moved smoothly and that can be easily assembled. .

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 in FIGS. 1 to 3 indicates a main shaft, which is provided between wheel supports 2 and 3 of a loading platform (not shown).

A wheel body 5 is rotatably provided on the main shaft 1 via a ball bearing 4.

One flange portion 6 is integrally formed on one side of the wheel body 5.

In addition, a boss portion 7 protruding from the center of the other side of the wheel body 5
A movable flange member 9 in the form of an annular plate is attached to the intermediate portion of the outer periphery via a hollow hard rubber ring 8 .

A cylindrical portion 10 is provided at the center of the movable flange member 9, and the hollow hard rubber ring 8 is housed inside the cylindrical portion 10.

Moreover, the other flange part 11 facing the one flange part 6 is integrally formed on the outer edge of the movable flange member 9.

Furthermore, a ring-shaped recess 12 is formed on the outer surface of the movable flange member 9.

On the other hand, a threaded portion 13 is formed on the outer peripheral surface of the outer end of the boss portion 7, and a threaded hole 15 formed at the center of a presser plate 14 having an annular plate shape is screwed into this threaded portion 13. has been done.

A ring-shaped protrusion 16 that engages with the recess 12 of the movable flange member 9 is formed at the outer peripheral edge of the inner surface of the presser plate 14 .

The presser plate 14 is configured to press the bottom surface of the recess 12 with its convex portion 16 to bring the flange portion 11 into contact with the other side surface of the wheel body 5.

Further, the holding plate 14 holds the movable flange member 9 between its convex portion 16 and the other side surface of the wheel body 5, and guides the movable flange member 9 as it moves in a direction perpendicular to the axis of the boss portion 7. It is made to be.

Further, the inner end side of the boss portion 7, that is, the wheel body 5
A position regulating portion 18 that extends from the boss portion 7 to the arm portion 17 and swells with a concave curved surface is formed at the connection portion with the arm portion 17 .

This position regulating part 18 is formed by taking a larger radius than usual at the connection part between the boss part 7 and the arm part 17 when the wheel body 5 is cast, and the hollow hard rubber ring 8 is formed at the boss part. 7 and prevents the movable flange member 9 from shifting from the vicinity of its center of gravity.

In addition, in FIGS. 1 and 2, 20.21 is an insulating bushing inserted on both ends of the main shaft 1, 22.23 is a retaining pin provided on both ends of the main shaft 1, and 24 is one side of the main shaft 1. The distance pieces 25 and 26 installed between the insulating bushing 22 and the ball bearing 4 are rails.

Next, to explain the operation of the above-mentioned running wheel, when passing a point, as shown in FIG. At the same time, the hollow hard rubber ring 8 is compressed and deformed.

When the movable flange member 9 completely rides on the rail 26, the end of the concave portion 12 of the movable flange member 9 engages with the convex portion 16 of the presser plate 14 and acts as a stopper, causing the movable flange member 9 to move unnecessarily. Restricted from moving.

After passing the point, the movable flange member 9 is guided by the holding plate 14 and returned to its original position by the restoring elastic force of the hollow hard rubber ring 8.

During the above operation, even if a force is applied to the hollow hard rubber ring 8 from the movable flange member 9 to move the hollow hard rubber ring 8 toward the inner end of the boss portion 7, the position regulating portion 18 The hollow hard rubber ring 8 does not move and remains in that position.

According to the above embodiment, the hollow hard rubber ring 8 is always positioned near the center of gravity of the movable flange member 9 by the position regulating portion 18, so the movable flange member 9 is stably supported, and the green glaze 1 There is no oscillation.

In other words, while a part of the outer surface of the movable flange member 9 comes into pressure contact with the press plate 14, a part of the inner surface does not come into pressure contact with the other side surface of the wheel body 5.

Therefore, the movable flange member 9 is guided by the holding plate 14 when passing the point, and moves up and down smoothly.

As explained above, according to the present invention, the movable flange member moves smoothly and there is no risk of derailment when passing a point, etc., resulting in safety.

Moreover, it is easy to assemble and does not require much time and effort.
