a) Title of the invention

Method and device for freezing ice of track connections.

b) Field of application of the invention

The invention relates to the safety of rail transport and transport by ice-free track connections, especially the switches and crossings.

c) Characteristic of the known technical solutions The components of the railways for rail transport include the substructure and the superstructure. The substructure is the earth body with dams, cut-outs and cut-outs, as well as traffic-necessary engineering structures,

z. As bridges, tunnels, etc .. For substructure one counts the rails, the iron, the sleepers and the bedding, so the actual track systems. Particularly sensitive parts of the track systems are the track connections, d. H. the switches and crossings.

Turnouts consist of tongue device (normally with two tongues each and jaw rails, tip lock as a hook lock or clamp tip lock), spacers and center piece with wing rail and track handle. The tongues as an essential part of the switches are either rotatable or resiliently mounted on sliding chairs. They are connected in pairs by tongue tie rods. The associated

Tip closure should guarantee the correct position of the tongues · The changeover movement takes place in three sections and requires that the or the switch bodies are not blocked by Scanee or Bis ·

Similarly, crossings at severe! Prost represent danger points.

The maintenance and care of the points are made by the Bahnmeisterei or the operating service.

Maintenance is often entrusted to the interlocking personnel, who do this work during breaks. If many points are present, additional staff is required, even for keeping clear the course of ash and slag, but especially for the passage in snow and ice. In severe frost, this can go so far that units of the army must be consulted to the goods transport and travel of the Reichsbahn, and z. To secure the transport of raw coal from open-pit operations to the power plants.

Already with entering frosty weather, the moving parts of the turnouts and their drives can freeze, as rain and sewage often can not be detected.

If possible, you can help with coal-heated, transportable switch boxes or with propane gas or electric heaters.

For steam diverter heating, steam is routed through a piping system that is routed to the stock rails and under the top closures. In the rod channel steam outlet openings are attached to this drilling system. During the critical winter period, this system must be constantly under steam. For very remote points this method is difficult to achieve. For long pipe routes, the steam cools or increases the insulation effort.

Recently, particularly in lignite opencast mines, it has become customary to temporarily move jet engines, which have been separated from aircraft aviation operations, to the frozen points for thawing. This is therefore also a rather complicated repair process, not a permanent preventive measure * The previous technical solutions thus require a high material, energy and human resources, if rail traffic should be maintained in frost and to avoid accidents ·

d) Object of the invention

The invention has a preventive long-term solution for Gängighaltung turnouts and crossings in any frosty weather without personnel expenses for the operation (except remote control) to the target ·

e) Presentation of the essence of the invention

The technical problem to be solved by the invention is to overcome the risk of icing on switches and crossings of rails and the Gängigaltung in all weather · At the same time can be kept as proposed also ash and slag and similar impurities largely without staff.

The cause of the previous shortcomings is that water, snow, ice, ash, slag, etc., only ever settle at the sensitive points and endanger the reliability · Features of the invention are the blowing away of all polluting and / or icy materials from the points area permanent or temporary or inter-

from the bottom, that is to say, without any obstacles in the way, in particular without obstructing rail traffic «

In the same way or at the same time, switch boxes, for example point machines, track lock drives and the like, can be kept free of snow and ice.

For this purpose, according to the invention a Schienenunterbaukörper \ anter.die switches, as well as point machines and / or intersections pushed, which contains upwardly directed nozzle openings and as required radiates compressed air with sufficient pressure, so that water, snow, bis and dirt are blown away.

The compressed air can be generated per substructure body by individual units or for several substructure body of a central compressed air system. The compressed air can also be heated ', z. · Electrical heating wires · Such substructure bodies can be prefabricated and mass-produced »They can first be connected to the rails and then exchanged in connection with overhauls of the track system. · They can also be pushed under routed points without the points to be exchanged ·

When switching to this process and such devices that can be produced in in-house rationalization workshops and can be made largely of concrete or concrete-like materials or with the concomitant use of plastics, the track maintenance would be possible even with cheers and thus road safety without the previous high manual effort. The solution according to the invention allows pernission and full automation.

f) embodiment

A schematic may illustrate the method and apparatus as an embodiment

 In the diagram:

- 1 track substructure body (as

Usable threshold.)

- 2 cavity for compressed air

- 3 outlet for compressed air -4 compressed air generator

- 5 rail.

- 6 points, consisting of tongues and joint

and guide rail

- 7 Bending device for the tongues; locking bars

- 8 nozzles ·

The track substructure or bodies 1 may be set in place of the sleepers or below the sleepers per diverter. They can be designed as a compact combination of multiple sleepers. The from the electric or fuel-driven compressed air generator 4, passing through the openings 3 compressed air ι fills the spaces 2 of the body 1 and exits through nozzles 8 upwards. The nozzles can be arranged and straightened so that the air meets the vulnerable points of the switch and thereby cleans and protects against freezing. These nozzles 8 can also be in joints? z. Ball joints, arranged and controlled so as to pivot or rotate automatically, in the belief that the entire area under consideration is optimally and safely cleaned. Thereby, the track with the rails 5, the switch 6 with tongues and accessories, as well as locking device 7 and other frost-threatened parts of the points system not only from dirt, snow or

Water is covered, so it remains ice-free and functional.

It is possible, in the area of the compressed air generator or in the lower rail body 1 at an appropriate point heating wires or infrared radiator additionally introduce and thus enhance the effect, such that even the strongest snowfall is compensated for the strongest frost · The rail body can be made of concrete or metal or combinations made of concrete and metal, even using inexpensive Eohstoffsubstituten, such as ash concrete, or even using suitable plastics ·

The design for the rail substructure body 1 can take place analogously to a single sleeper or a threshold dressing or so that the actual sleepers rest. The operation of the compressed air generator 4 · can be triggered on this directly or via transmission lines or via radio link. It can be used for temporary continuous operation or in automatic intervals.
