Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rail having a U-shaped cross section that supports a rotating wheel, its composite rail and support structure, and a rail laying device.

Conventionally, railcars have two types of rotating wheels: a regulating wheel to prevent floating and a wheel to support the load. They are sandwiched from above and below to prevent the wheels from coming off. This is because a single rail can easily form a curve.

However, it is impossible to support a high-speed, heavy-load vehicle body using a single rail, mainly for the following reasons.

(a) The air resistance of the upper and lower two stages of rotating wheels that are spaced apart is large. (b) The space above and below the rail must be large;
Since the vehicle height becomes high, it is difficult to increase the wheel diameter.

Therefore, economical effects such as speed are also reduced.

(c) The support structure becomes complicated to apply a large load to a single rail installed laterally.

However, by making the difference in height between the two-stage driving wheels small to reduce air resistance and increasing the diameter to increase speed efficiency, making the rails with a U-shaped cross section thicker and adding support and fixing pieces makes the rails curved. make things difficult.

The present invention provides a composite track that makes it possible to lay rail curves by tightening with practical technology, maintains strength over long distances even without supporting materials, and further provides a support structure that is easy to fix, such as columns and sleepers. The aim is to realize a stable track with low cost and a small number of parts. Furthermore, the purpose is to facilitate replacement when worn out, prevent wheels from coming off, and realize vehicles with wheels that do not engage with each other, with low noise and high speed.

To explain this in detail with drawings, Example 1 (see Figures 1 to 5) In this example, as the material for the rail, iron is mainly used for the practical large rail, and aluminum alloy is used for the horizontal type of the hole cover. Or, it is a track that can also use plastics.

Of these, one example of a large rail, ie one made of iron material, will be described in detail.The long rail 1 has a U-shaped cross section, has a rising wall extending vertically, and is provided with an upper edge 8 of the presser foot and a lower edge 9 of the presser foot. A pair of poles, with their U-shaped inner surfaces facing each other, are elevated on the pillars 2 and 4.

This support 2 is made of H-beam steel, and the upper part of the support 2 is covered with a flat iron plate 2-1 welded together.

The upper surface of this support 2 and the edge of the upper edge of the presser foot of the rail are on the same level, and one piece of the U-shaped presser 3 with both sides bent is engaged with the upper edge of the presser foot, and the other piece is on the outside of the support. , and a presser bolt 13 is fixed to the flat iron plate 2-1.

Further, at the bottom, the lower edge of the presser foot is pressed from inside against the column 2 by a pusher plate 5 inserted under the guide piece of the rail, and the pusher plate 5 is made of H-shaped steel with bolts 15. It is fixed to Yokosho 4.

Further, the horizontal beams 4 are welded to the columns 2, and the left and right columns provided at a predetermined interval are fixed together.

A shoring material 7 is installed between the above-mentioned support 2 and the support column, and like the support support 2 and the crossbar 4, a holding device 3 and a push plate 5 are used to maintain the spacing between the rails and prevent twisting. There is.

As mentioned above, H-shaped steel is used in this example, but it is obvious that other shapes, round or square pipes, etc. can also be used.

Thus, in this example, the rail can be easily removed by removing the bolts 13 and 15, and it is extremely easy to install it.Since the rail 1 has a simple shape, slight curves can be removed by the laying device 10 ( (described later), and since the outer surface of the rising wall is in close contact with the support 2 and the rail 1, it is stably supported.

According to the present invention, there is no need to drill holes in the rail, and the rail is pressed into contact with a holding metal fitting, a press plate, etc., so when the rail expands and contracts due to temperature differences, it allows a slight sliding action and prevents bending or distortion. , the effect of ensuring smooth operation of the wheels is produced.

Embodiment 2 (See Figure 6) This example is an example of a composite track, in which the concrete auxiliary rail 21 with an L-shaped cross section has a trapezoidal cross section that expands downward, and the embedded bolts 13- 1 and 15-1 are bent downward and embedded.

The presser edge of the rail 1 is engaged with the presser 3 and fixed to the upper surface of the auxiliary rail 21 with a tightening bolt 13-1 and a nut, and the lower edge of the presser is a rotating presser plate (described later). regulated. In this way, the rail 1 and the auxiliary rail 21 are integrated to form a composite track.

This compound track has a U-shaped cross section of the rail 1 facing inward on both sides of sleepers 4-1 with low supports, and the column force pushes the inner lower slope of the auxiliary rail 21. Board 5-
2, and is tightened with a nut using an embedded tightening bolt 15-1.

Further, the lower part of the outer wall of the auxiliary rail is closely supported by the inner wall of a low support provided at the end of the sleeper 4-1.

Since the composite track of this example can reduce the number of supporting materials or sleepers, it is desirable to build it elevated on supports and to use it for straight courses where there is not much lateral load.

In this example, the rail 1 is brought into close contact with the auxiliary rail 21, and the method of supporting the auxiliary rail and the rail using the presser 3 and rotating press plate 5-1 is the same as that of Example-1, so the temperature difference When the rail expands and contracts, it allows a slight sliding action and prevents bending or distortion, which has the effect of ensuring smooth running of the wheels, and is also extremely easy to replace.

Example 3 (See Figures 7, 8, and 9) This example is an example of a compound track like the previous example, and is preferably used mainly for curves.The auxiliary rail 21 with an L-shaped cross section is made of reinforced concrete. There are embedded bolts 13-1 and 15-1 embedded in predetermined positions with their screw heads slightly exposed. As in the previous two examples, the rail 1, the auxiliary rail 21, and the H-steel support 2 are integrally fastened to the upper part using the holding tool 3.

Further, under the guide piece at the lower stage of the rail 1, a rotating push plate 5-1 has an embedded embedded bolt 15-1 between it and the base of the auxiliary rail 21.
1, and rotate it in the direction of the arrow in Fig. 9 to the position shown in Fig. 8, pressing the upper edge of the presser foot of rail 1 against the rising wall of the auxiliary rail. I support it.

This composite rail is stably supported downwardly by being pressed in the direction of the support column 2 by a pressing plate 5-2.

The operation and effect of this example are the same as those of the previous two examples, and since the shape of the auxiliary rail is simple, it is easy to manufacture a curved shape, which is advantageous in terms of cost.

Example 4 (See Figures 10, 11 (a) and (b)) In this example, when the rail is placed on a crossbeam, sleeper, or shoring material, the rail used to bring it into close contact with the support is curved. This is a laying device for

In other words, when a rail is placed on the cross beams 4 of a pair of column columns whose positions are curved along the planned line, the rail 1 is slightly moved in the direction of arrow A or arrow B as shown in FIG. Since it is difficult to perform this curving work manually, the laying device of the present invention is used.

To give the simplest example of the laying device 10 and explain it in detail with reference to the drawings, the securing plate 10-1 is placed on the outside of the support column, and the four arm bones 10-4 provided on the corresponding plate 10-1 are used to connect the clamping plate 10-1. 2 is supported at a predetermined distance inside the rail, and the extrusion plate 10-8 is attached to the inner tip of the extrusion tool 10-5, which is passed through a screw hole of a through hole provided at a predetermined position of the clamping plate 10-2. Attach the extrusion plate 10-8 to the roller 1
A rotary rod 10-7 is provided on an extruder 10-6 provided at the outer tip of the extrusion tool 10-5.

Thus, the extruder 10-6 is rotated by the rotary rod 10-7,
By pressing in the direction of the arrow, curvature in the direction of arrow A or B can be achieved and it can be attached to a predetermined position using a presser or a presser plate as in the previous example.

The extrusion tool 10-5, extruder 10-6, etc. can be made more powerful by incorporating hydraulic control or the like.

Furthermore, when the pressing curved plate is bent inward, it is natural to use a reversely curved pressing plate.

The purpose of interposing the rollers between the pressing curved plate and the pushing plate is to ensure smooth sliding when the rail slides in one direction due to curving.

The present invention makes it possible to curve and lay rails with large cross sections on site.
