Description

High-temperature air jet heating system {A HIGH TEMPERATURE AIR JET HEATING SYSTEM}

The present invention relates to a system applied to a railway rail to prevent ice formation on the surface of the rail, and more particularly, to a system for snow accumulation or ice formation on the railway rail by spraying high-temperature air to the surface of the railway rail. It relates to a high-temperature air injection heating system for preventing

The present invention relates to a heating system for preventing railroad tracks from freezing, and more particularly, by generating high-temperature air using an induction heating element and discharging it toward the railroad tracks to prevent freezing of railroad tracks or accumulation of snow on the railroad tracks. It is about a 'rail icing prevention system' for

As is well known, for the safe operation of trains, the tracks must always be maintained in optimal conditions.

That is, when foreign substances (eg, ice, nails, trees, etc.) do not exist on the track, derailment of the train can be prevented, and normal operation of various operating devices or safety devices installed on the track can be guaranteed. .

For example, in the case of a switch, if a foreign substance is stuck in the gap between the switched tracks, or if ice or snow accumulates, it will not operate properly, causing the train to derail, roll over, or not go in the desired direction. In case of accident, it causes collision and collision accidents, and train automatic control devices {e.g. ATS (AUTOMATIC TRAIN STOPPER: automatic train stop device), ATC (AUTOMATIC TRAIN CONTROL: automatic train control device), ATO (AUTOMATIC TRAIN OPERATION: automatic train operation device) )}, if both tracks are short-circuited due to snow, ice or moisture, etc., an error occurs in the signal system and the train cannot operate normally.

Therefore, in order to prevent the above problems from occurring, workers always check the lines to keep them in optimal condition.

However, among foreign substances, ice or snow covers a very wide area, cannot be easily distinguished with the naked eye, and it is not easy to remove them. It wasn't too difficult.

In other words, in the case of ice, it is not easy to see, and if the weather is cold, it occurs randomly in an unspecified area and can reappear immediately after removal. In the case of snow, it is not easy to remove it, and it is continuous In case of snowfall, it was quite difficult to achieve the intended purpose due to lack of manpower and time. //

In general, a railroad turnout is a facility installed on a track to move a railroad vehicle from one track to another.

Such a railway turnout is a basic rail composed of a pair of rails, a tung rail installed parallel to the basic rail, and a track that operates the tung rail so that the railroad vehicle selects and runs on any one pair of rails from the basic rail and the tung rail It consists of a point part including a switcher, a lead part in which a basic rail and a tongue rail coexist, and a crossing part composed of a part where the wheels of a railroad vehicle cross each other according to the selection of the traveling direction of the railroad vehicle.

The railroad junction configured as described above has a problem in that railroad accidents occur due to malfunctions such as the tongue rail not operating properly due to heavy snow and freezing in winter.

An example of a technique for solving this problem is disclosed in Patent Document 1 below.

However, in the case of Patent Document 1, although the installation of the heating element is easy, there is a problem in that the heating range is limited and the heat conduction efficiency is low, so snow or ice accumulated between the basic rail and the tongue rail cannot be properly removed.

In Patent Literature 2, air curtains (blocks) are formed by spraying compressed and/or heated air to the points and crossings of the branching parts and crossings during snowfall, so that the snow falling on the points and crossings is blown away so that the snow does not accumulate. In a line branch protection system for melting accumulated snow, an air inlet for inhaling external air, a sensor unit in which a sensor for detecting ambient temperature, snowfall, etc. is installed, and the inhaled external air When is detected as minus 1 degree Celsius or less by the sensor unit, a heating unit for heating the heater member, a compression and blower unit for compressing and sending the intake/heated air to the pipe unit, and supplying power An air conditioner including an AC or DC power supply unit and a control unit for controlling the operation of the unit; an indoor control unit connected to the control unit by wire or wireless to remotely operate the air conditioner; A plurality of upward discharge nozzles installed on both sides of the line along the branching part of the line at a position 60 cm higher than the height of the line, and respectively injecting compressed air through which the air compressed/heated from the air conditioner passes inward at an upward angle of 45 degrees. A rail side pipe part including at least one compressed air discharge part having a plurality of horizontal discharge nozzles respectively ejecting compressed air horizontally and a plurality of vertically downward discharge nozzles respectively ejecting compressed air downward; and a plurality of upward discharge nozzles branching from the rail side pipe part and traversing side by side with the sleepers supporting the rail, and injecting compressed air through which the air compressed/heated from the air conditioner passes toward the rail, wherein the sleeper and the sleeper A line branching protection system including at least one rail crossing pipe part arranged therebetween is disclosed.

However, in the case of Patent Document 2, an air curtain is formed by spraying compressed air to a predetermined area of a line switch installed on a line branch to prevent snow or foreign matter from fundamentally accumulating, and performance compared to the conventional heating system method. However, there is a problem in that the system is complex and requires a lot of installation cost, maintenance and repair cost of the system.
