Abstract

The invention relates to an installation for cleaning and defrosting railways by means of the salt and the gases as a result of burning fuel used by Diesel locomotives meant to clear the snow. According to the invention, the installation applies the process for removing the snow and the ice from the railways (9), by means of the hot flux of exhaust gases resulting after burning the fuel used for operating the Diesel engines endowing some locomotives (11), and comprises a closing cover (2), situated above a chimney (1) for exhausting gases as a result of burning the fuel, and, simultaneously it actuates a hinged valve (12) for releasing the high granulation salt, placed in a basin (5) meant for storing salt, the salt quantity needed for the intervention being introduced through the upper side of the basin (5) tightly closed with the closing cover (2), when actuating the hinged valve (12) for releasing the salt there being also actuated a helical worm (6), which displaces the salt from both lateral directions towards the middle of the basin (5) for storing salt, in said place there existing a hole for releasing the salt by means of a rectangular profile (8), thermally insulated, due to the flux of gases burnt under pressure, with a very high constant temperature, which is displaced through some thermally insulated pipes (3), a free space (10) situated between a support (4) of the basin (5) meant for storing the salt is heated, thus there being a dry environment, and the salt with high granulation is kept dry along the entire displacement of the locomotive (11), thus preventing the salt deposition onto the walls of the basin (5), as well as onto the rectangular profile (8) for releasing the salt onto the surface of the railways (9), thus preventing their re-frosting for a time period, on each intervention locomotive (9) there existing an installation on each side thereof, placed on the front side, along the displacement direction, behind a protection shield (13).

Installation for cleaning and defrosting railway rails with the help of salt and gas as a result of the combustion of fuel used by diesel locomotives intended for snow removal.

The present invention relates to an installation and process, used for cleaning and defrosting railway tracks, in areas with climatic problems and massive snowfalls.

U.S. Patent No. 4,313,045 is known, which refers to a similar installation.

The problem solved by the invention is the removal of the layer of frozen snow from the surface of the railway rails.

To understand the proposal, we suggest an application based on a recent incident in an area of Romania.

A train set (people or goods) remained snowy due to the strong blizzard and got stuck on a section of railway. It was immediately decided to send two diesel locomotives equipped with classic cleaning and snow removal devices. At one point the two locomotives snowed and could no longer reach the blocked train set. It was found that the classic snow removal plow system did not solve the problem of ice removal on the rail tracks.

The invention "Cleaning and defrosting the rail tracks with salt and gas as a result of burning fuel used by diesel locomotives for snow removal" solves the problem by eliminating the freezing process of the snow layer and the film of water left on railway rails 9.

For this purpose, the snow and ice removal procedure on the railway tracks 9 is applied with the help of the hot flow of exhaust gases resulting from the combustion of the fuel used for the operation of diesel engines, which are equipped with locomotives 11 for snow removal and interventions.

For this purpose, we equipped the two 11 diesel locomotives for snow removal and maintenance with two installations shown in figure 1.

Both locomotives will be positioned back to back, towing each other to the locking and snow section of the train set. At that moment, the driver of the locomotive in front, in the direction of travel, will manually engage the shut-off cap 2 above the gas outlet chimney 1 as a result of burning fuel and simultaneously operate the release valve 12 of the salt with large granulation, located in basin 5 for salt storage.

The amount of salt required for the intervention is introduced through the upper part of basin 5, which is hermetically sealed with a lid to close basin 5.

When the salt release flap is actuated, the helical auger 6 will also be actuated, moving the salt from both sides, sideways, towards the middle of the salt storage tank 5, where the salt release mouth is located by means of the thermally insulated rectangular profile 8.

Due to the flow of flue gases under pressure, with a constant very high temperature, which moves through the thermally insulated pipes 3, the free space 10 located between the support of basin 4 and basin 5 intended for salt storage, will be heated, thus creating an environment dry, and the high granular salt is kept dry throughout the journey

0 10-00254-1 9 -03- 2010 locomotive, preventing the deposition of salt on the walls of the basin 5 as well as on the rectangular profile 8 of release of salt on the surface of the railway rails 9, thus preventing their re-freezing for a period of time.

The hot gas acts as a pressurized stream, releasing portions of ice and snow on the surface of the rail tracks 9. Once the locomotives reach the locking place of the train set, it will be coupled to the intervention locomotives, while which the mechanic of the second intervention locomotive will in turn operate the defrosting and cleaning installation of the rail decal rails to remove any new deposits of snow and ice on the way back, until the exit from the snowy area.

On an intervention locomotive there will be an installation on each side of it, located in the front on the direction of travel, behind the protection shield 13 of the locomotive 11.

Compared to the classic system mounted on snow removal locomotives, the installation and process proposed as an invention provide the guarantee that any snow-covered train set will be able to be released and towed safely.

Also, the existing system has the disadvantage that it only superficially cleans the railway tracks, instead the proposed installation and process, as inventions, also defrosts, due to the proposed procedure as a novelty, by reusing the gases resulting from burning fuel used to run the locomotive's diesel engine. intervention.

Compared to other existing installations and classic devices on the market, the proposed installation can be done in a very short time and with low costs, being able to be applied on any type of diesel locomotive, with small adaptations and the training of qualified personnel is carried out. a short time.

It is not necessary to use special materials that would involve high costs, leading to its application on as many snow and locomotive equipment as possible, without requiring additional personnel to remove and release the effects of snow.

The following is an example of the embodiment of the invention in connection with Figure 1 which represents the complete snow removal and defrosting installation mounted on a diesel locomotive:

position 1 - gas exhaust basket;

position 2 - flue gas basket closing cap (manually operated from the cab by the mechanic);

position 3 - thermally insulated pipe (for the transport of gas flow);

position 4 - support for the salt storage basin;

position 5 - salt storage basin;

position 6 - snail stg.-dr. (for moving the salt from the side directions to the centrally positioned release port);

position 7 - salt storage tank closure cap;

position 8 - thermally insulated rectangular profile 9 for salt spreading on railway tracks);

position 9 - railway track;

(Ν- 2 Ο 1 Ο - Ο Ο 2 5 4 - 1 9 -03- 2010 position 10 - free space between the salt storage basin and its support;
