DE102007020204A1 - Storage for storing the points and the core parts of grooved rails - Google Patents

Abstract

The bearing has a mat (5) arranged below a shunting switch body (2K) and a frog body, where the mat is made of a foam material. The mat exhibits multiple recesses (6) in irregular distances, where spring bodies (7) are fitted in the respective recesses. A metal sheet (8) is arranged between the shunting switch body and the frog body and/or between the shunting switch body and the mat. A filling material (9) is arranged in a housing (4), where the filling material lies on the shunting switch body and frog body. The spring bodies are made of rubbery-elastic material.

Description

The The invention relates to a storage for storing the switches and the Centerpieces of grooved rails, with the switches at least a switch body and the core pieces at least have a heart piece body of a includes open-topped housing, and wherein the forming the track Grooved rails are mounted elastically.

give way and heart pieces of grooved rails are special track constructions, which are usually designed so that the rails in the area a switch are movable only in the transverse direction while the rails in the area of a heart no movements can execute. The known bearings for The track constructions of the aforementioned type are predominantly so designed that the rails carrying the track construction Support plate is rigidly connected to the substructure. With these bearings is a movement of the rails in the vertical direction and thus also no sound insulation in the area of the special track construction possible.

Outside the special track constructions provided elastic bearings Although the rails cause a very extensive on the track Soundproofing, but in the areas of special Track constructions, such as switches and frogs, not affects more.

Although it is already known a bearing for storing special track structures, in which the switch body and the heart body are elastically mounted ( EP 1 484 447 A2 ). Here, the switch body and the heart piece body are covered by an open-top frame and intermediate layers of rubber or rubber-elastic plastic are arranged between the switch body or the heart piece body and the side surfaces of the frame. Further, a free space is provided between the lower boundary surface of the switch body or the core body and the lower surface of the frame. This storage requires a special shape for the switch bodies and the body pieces, so that this storage can be applied only to new track structures. For existing switches and frogs known storage is not suitable.

Of the Invention is based on the object, a sound-absorbing Storage for storing turnouts and frogs Rill rails form such that they both new as can also be applied to existing track structures.

The Solution of the problem is in storage of the type mentioned in that under the switch body and the frog body in each case a mat Foam is arranged in irregular Intervals have recesses in which spring body are fitted, and that between the switch body and the Centerpiece body on the one hand and the mat made of foam on the other hand, a sheet is arranged. The sheet is with the Turnout body or with the frog body welded. Through the mat of foam are the spring body fixed in their position.

To Another feature of the invention is in the housing to the switch bodies and to the heart pieces fitting filling body is arranged and is the remaining one Spilled space of the housing with an elastic material. The fillings serve only to the required Amount of elastic material for casting to keep the housing low, and therefore can consist of any, cheapest possible material. The elastic material for casting the housing is suitably made of polyurethane.

at this embodiment of storage has the mat made of foam the more task to prevent when casting the housing of the elastic material in the air gap between the lower edge of the switch body or of the frog body and the housing can flow.

The inventive design of the new storage allows it by determining the size the spring body and their number or by the determination the distance of the spring body from each other, the deflection the switch and the heart piece very precisely.

The Fed body suitably exist made of rubber-elastic material, so for example made of rubber or made of rubber-elastic plastic.

In Embodiment of the invention have the recesses in the mats made of foam and the spring body a round cross-section on, in a further embodiment of the invention, the diameter all recesses in the mat of foam and all spring body have the same degree. Such mats made of foam and such spring bodies are very light and inexpensive manufacture. In addition, by this configuration the mats made of foam and the spring body whose storage much easier.

In the drawing, an embodiment of the storage according to the invention for storing the switches and the heart pieces of grooved rails is posed. Show it:

1 a plan view of a track section with a switch and with a heart;

2 a section along the line II-II in 1 , turned by 90 degrees;

3 a section along the line III-III in 1 , also rotated by 90 °;

4 a plan view of the in the in the

1 shown track section arranged switch arranged mats made of foam;

5 one in the mats foam to be fitted spring body in front view.

At the in 1 shown, from grooved rails 1 formed track section are a switch 2 and a centerpiece 3 intended.

As 2 and 3 show, the grooved rail 1 ( 2 ) and the switch body 2K in which the tongue 1Z the grooved rail 1 is guided ( 3 ) from an upwardly open housing 4 includes. Corresponding 3 is also the core body, not shown, of the upwardly open housing 4 includes. Between the lower surfaces of the rail 1 , the turnout body 2K and the frog body on the one hand and the bottom of the housing 4 On the other hand, each is a mat 5 made of foam, which at irregular intervals recesses 6 having. In the recesses 6 are spring bodies 7 fitted. Furthermore, between the switch body 2K and the centerpiece body on the one hand and the mat 5 made of foam on the other hand, a sheet 8th arranged. In the case 4 are to the switch body 2K and the center piece body fitting filler 9 arranged. The remaining space of the housing 4 is with an elastic material 10 shed.

4 shows that the recesses 6 in the mats 5 made of foam and the spring bodies 7 have a round cross-section and that the recesses 6 in the mats 5 made of foam at irregular intervals from each other.

Out 5 It can be seen that - to a compression of the spring body 7 to allow - the feather twill 7 around its entire circumference a recess 11 exhibit.
