Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a technique for automatically igniting a snow melting device by remote control in a snow melting device that melts snow accumulated on a branching device of a railway track so that a point operates normally.
[0002]
[Prior art]
On the railroad tracks in heavy snow areas, when snow falls, the snow accumulates on the turnout and the points cannot be switched. Therefore, when snow begins to fall or when snow is expected, the snow that has fallen on the turnout is melted and removed using a snow melting device.
Conventional snow melting is carried out by installing a plurality of snow melting kantera on a branch rail and igniting each snow melting kantera one by one when a snowfall or snowfall is expected. Also, each snowmelt cantera contained only a predetermined amount of fuel, and when it was used up, the station staff replenished the fuel.
[0003]
[Problems to be solved by the invention]
However, in the snow melting Cantera system where the station staff performs ignition work, it is necessary for the station staff to enter the branching section of the station directly, which may cause a contact accident with the train. there were. For this reason, there is a drawback that it is necessary to watch the train and to require a lot of manpower. In addition, the ignition work has to be performed in a so-called train interval between the passage of a train and the passage of the next train, which has a drawback that the working time is greatly limited.
Further, after ignition, it is usually left as it is, and even if the combustion flame disappears due to wind, train wind pressure, etc., this could not be easily confirmed.
Furthermore, there are many branches in the station premises, and it may take several hours for one person to ignite the snow melting cantera at all these branches, which is not only heavy labor but also inefficient. there were.

DETAILED DESCRIPTION OF THE INVENTION
The configuration of the present invention will be described below based on the embodiment of the invention shown in the drawings. 1 to 4 relate to an embodiment of the present invention, and FIG. 1 is a schematic diagram showing the entire system of an automatic ignition type snow melting device. FIG. 2A is a side view of the combustion apparatus 1 as viewed from the mounting surface side to the rail 2, FIG. 2B is a plan view of the combustion chamber covering material (cover) 3, and FIG. FIG. 3A is a cross-sectional view taken along line XX of FIG. 2 during fire extinguishing, FIG. 3B is a cross-sectional view taken along line XX during combustion, and FIG. 4 is a control device 4 for controlling the combustion apparatus 1. FIG.
[0008]
As shown in the figure, in this embodiment, two combustion devices 1 are attached to the side surface of the rail 2 at the branch portion of the railroad track. In these combustion apparatuses 1, fuel is supplied from a fuel tank (kerosene) 5, and an igniter 6 is ON / OFF controlled by a control device 4 installed near a branching part on site. It is like that. The control device 4 includes a communication device 7 such as a PHS, and can transmit and receive with a communication device 9 of a remote command device 8 such as a station base station.
[0009]
As shown in FIGS. 2 and 3, the combustion apparatus 1 is provided with a combustion chamber case 11 having an open side on the upper side in a main body case 10. A core material (not shown) for burning kerosene as fuel is attached to the bottom of the combustion chamber case 11, and the inside forms a combustion chamber 12. A kerosene refueling device 13 is attached at a position opposite to the rail 2 side of the main body case 10. An igniter 6 is disposed between the combustion chamber case 11 and the main body case 10 on the end face side parallel to the rail 2. The igniter 6 includes a ceramic heater 14 that is heated to approximately 1200 ° C., and a tip portion of the igniter 6 is disposed close to the core material in the combustion chamber 12.
[0010]
A temperature sensor 15 is attached to the rail side surface of the combustion chamber case 11 via a bracket 16. The temperature signal detected by the temperature sensor 15 is output to the control device 4. A metal cover 17 is attached to the side surface and the upper surface side of the main body case 10 opposite to the rail 2. Furthermore, a covering material (cover) 3 such as celluloid that disappears due to combustion is fitted and attached to the upper surface side opening where the combustion flame of the combustion chamber case 11 exits.
A leaf spring 18 is attached in the vicinity of the ceramic heater 14 of the igniter 6. The leaf spring 18 is used to cause the wick of the main body combustion section to be installed with a ceramic heater at an appropriate position, and at the same time, can be easily attached and detached during cleaning and maintenance of the wick. In FIG. 2A, reference numeral 19 denotes a flexible electric wiring cable, and reference numeral 20 denotes a rainproof rubber outlet.
[0011]
In the automatic ignition type snow melting device configured as described above, when not in use, the cover 3 such as celluloid remains fitted and attached to the opening on the upper surface side of the combustion chamber case 11. As a result, it is possible to prevent rain and wind from entering and rain water soaking into the combustion core material (light core), and preventing the rail and wheel wear dust from traveling on the train from adhering to the combustion core material. . Therefore, it is not difficult to ignite the core material due to rain water, abrasion dust, or the like.
[0012]
Thus, when snow is expected or when it snows, the rail 2 at the point is heated so that the point rail at the bifurcation operates normally, and when snow is piled up or snow is melting, In addition, when the snow is frozen, it is important to melt the ice so that the point operation is not hindered. Therefore, in the present embodiment, a command signal for operating the snow melting device 1 is output from the remote commanding device 8 installed in the track maintenance base station or the like. This command signal is transmitted to the on-site wireless communication device 7 through the wireless communication device 9 such as PHS, and is input to the on-site control device 4. In response to the command signal, the control device 4 outputs a refueling start signal to the fuel tank 5 of the snow melting device 1 and energizes the ceramic heater 14 of the igniter 6 in response to the command signal as shown in the block circuit diagram of FIG. Turn on. The ceramic heater 14 is heated to approximately 1200 ° C.
[0013]
The kerosene supplied from the fuel tank 5 is once supplied to the kerosene refueling device 13 of the combustion apparatus 1, and a certain amount is stocked here. And it is supplied to the combustion chamber 12 from the kerosene fueling device 13, is sucked up by the core material of the combustion chamber 12, is ignited by the ceramic heater 14 disposed in the vicinity of the core material, and burns. The combustion flame first disappears by burning the cover 3 made of celluloid or the like covered by the opening on the upper surface side of the combustion chamber case 11. After the cover 3 disappears, the combustion flame reaches around the neck 2A of the rail 2 as shown in FIG. 3B, and the rail side surface is heated by radiant heat transfer.
[0014]
As a result, the temperature of the rail 2 gradually increases, and a region having a high temperature gradually expands due to heat conduction, so that the snow around the rail 2 is melted and the frozen rail portion is melted. That is, it is possible to ensure a normal point switching operation.
Combustion continues until the supplied kerosene is exhausted, so when there is no longer a need for melting snow, station employees go to the site and perform fire extinguishing work.
[0015]
When the combustion flame does not ignite, the ignition control is repeated at 5-minute intervals by a retry function for 30 minutes. Also, once ignited, the controller enters a monitoring mode, and if the fire is extinguished due to train wind pressure or some reason within 8 hours after ignition, the control unit is controlled by an output signal from the temperature sensor 15 attached to the side of the combustion chamber case 11. 4 detects this and outputs a signal to the combustion apparatus 1 so as to try the ignition operation again, or gives a warning and display of the occurrence of a failure, and notifies the remote commander 8 and the station staff of the station 21. The station staff will perform the restoration work. Then, after the restoration work is completed, the fact that the combustion apparatus 1 has been restored is transmitted to the remote commander 8, and the remote commander 8 is reset to re-command the above ignition operation.
Thus, once the snow melting operation is performed by the snow melting device, the cover 3 has disappeared from the opening on the upper surface side of the combustion chamber 12, so that a new cover 3 needs to be set again. This operation may be performed until the next snow melting apparatus is operated, and is extremely flexible.
[0016]
By the way, this invention is not limited to embodiment mentioned above, A suitable change is possible. For example, the communication method is exemplified by a wireless method using PHS, but may be a wired method. In addition, the fire extinguishing work has been described as being performed by a station employee, but it can also be performed automatically by shutting off the fuel supply path using a communication line as in the case of ignition.
[0017]
【The invention's effect】
As described above, in the automatic ignition type snow melting device of the present invention, the combustion device attached to the branch rail, the fuel tank for supplying fuel to the combustion device, and the control device for controlling the igniter of the combustion device And a remote commanding device that outputs a command signal to the control device via a communication line. When a snowfall or snowfall is expected, a remote commander that is far away from the site such as a station base station The command device can output a command signal through a communication line to the control device at the site, and can automatically ignite the igniter of the snow melting device attached to the side of the rail by performing an ON operation. Therefore, there is no need for the worker to get off the train track, danger is avoided, and the worker can be omitted, which is extremely efficient. Further, the ignition operation can be performed simultaneously on a plurality of combustion devices, and is extremely efficient.
[0018]
Further, in the present invention, since the upper surface side opening of the combustion chamber of the combustion apparatus is covered with the material that disappears by combustion, the rain water and the train wheel are passed through the opening where the combustion flame of the combustion chamber exits. In addition, there is no possibility that it becomes difficult to ignite by the wear dust of the rail entering.
