Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a cantera for snow melting and freezing prevention for railway tracks.

0002

[Technical background]

Railway rails, especially the moving parts of the rails in switch machines, are used in cold regions, snowy regions, or At the point when freezing or snow accumulation is predicted during snowfall, a method known as "snow melting cantera" is used. A heating device is used.

0003

[Conventional technology]

As its name suggests, the snow-melting cantera described above is mainly a flame generator that uses white kerosene as fuel. The basic form of the heating means is as follows.

0004

[Problem that the idea aims to solve]

As mentioned above, most of the snow melting canteras are in the form of flames that use white kerosene as fuel. Types with this basic form have been used since relatively ancient times.

[0005] In addition, a small number of devices using electric heaters as the heat source have been used on a trial basis. However, this kind of heater is installed directly or indirectly on the track. Although it is convenient to use, it is completely incomparable with the above-mentioned flame-starting type in terms of cost. The efficiency was so low that it could not be compared.

[0006] The former type, which uses white kerosene as fuel (hereinafter referred to as the flame type), is of course suitable for outdoor use. Therefore, the flow of flames due to wind direction, the frequency of passing vehicles, and the Heat generation and loss of heat due to the wind generated during passage, soot generation due to incomplete combustion, etc. In addition to the formation of heat insulating parts by the raw soot, it is also used for seasonal use and for other safety purposes. Since it is impossible to install permanent installation and oil supply piping according to the standard, these snow melting canteras At the time when the equipment is expected to be used, installation work, removal work at the end of use, and During operation, refueling, maintenance, inspection, etc. all rely on manual labor, all of which are carried out in the bitter cold. There is also a lot of late-night work under adverse conditions, and regular inspections and replenishment work is essential. This is a very difficult task.

[0007] On the other hand, as mentioned above, using electricity as a heat source other than white kerosene Although this has been raised as a development issue for some time, as mentioned above, electric heaters Using rails directly or indirectly due to the heat generated by The number of cases in which the applicant was rejected due to these factors was the highest.

[0008] This idea basically uses an electric heater as a heat source. However, air is used as a transmission medium to heat the rails, and the air is used to heat the rails and rails as so-called hot air. This makes it possible to prevent freezing and melt snow by heating the atmosphere. The purpose is to

[0009]

[Means to solve the problem]

This idea has a built-in electric heater as a means to achieve the above purpose. A blower is installed at the base end of the heated hot air tunnel, and a vent branched into two directions, left and right, is installed at the tip. It is connected to and communicates with the middle part of one side wall of the wind tunnel, and discharge ports are opened at both ends of the ventilation tunnel. It is possible to blow out hot air along the longitudinal direction of the basic rail and the movable rail. It is characterized by being configured so that it can be

[Effect]

This idea is designed to prevent snow accumulation and freezing of switchgear in winter and extremely cold seasons. In particular, in switching machines, movable rails with sharp ends are It is used to maintain the movable state of the target, and is heated in a hot wind tunnel. The forced-flow air generated by the blower is heated and the heated electric heater is heated. A movable rail whose purpose is to heat hot air from the outlet of a ventilation tunnel connected to a hot wind tunnel. and along the basic rail, and along the movable rail and the basic rail. It heats the atmosphere within the movable range.

[0011] In particular, the movable rail with a sharp tip in a switch machine is It can be installed at However, this movable rail and sliding plate freeze, and the movable rail and basic track This prevents the vehicle from becoming immovable due to freezing with the rows, and also prevents the base from becoming immobile during snowfall. Snow accumulates in the small gap between the book rail and the movable rail, inhibiting the movement of the movable rail. This is an attempt to prevent elephants.

0012 On the sliding surface of the sliding plate on which the movable rail is placed and made slidable, Sufficient lubrication oil is applied at all times, and usually the joint between the movable rail and sliding plate is Even if some moisture is supplied to the part, the water will be volatilized by the lubricating oil and the moisture will be removed. There is no need to place too much emphasis on freezing due to snowfall. If the purpose is to prevent freezing in cold regions, increase the ambient temperature even slightly. As a result, the movable rail receives this heat and is exposed to dew condensation due to attached moisture. It can protect against freezing phenomena during winter, and it can also protect against freezing phenomena during snowfall. In the movable range of the moving rail, the snow melts due to the heating of the atmosphere and snow accumulates before snow falls. It also prevents the movable rails from accumulating water melted in the atmosphere. It can be flushed out by heating.

[0013] The device of this invention divides the tip of the hot air tunnel, which sends out heated air, into two parts in the left and right direction. A ventilation tunnel that can branch out and blow out hot air from a discharge port at the tip is connected to the hot wind tunnel. It is formed into a T-shape in plan view, and mainly consists of the inner surface of the base, where the ventilation tunnel is the basic part, and the sharp tip. It is installed in the gap formed by the movable rail, which is similar to the hot air tunnel described above. The air blower can be placed outside the rail by passing under the rail.

[0014] The hot air blown out from the outlet of these ventilation tunnels is formed by the movable rail and the basic rail. The wind blows through following the air path formed with the width of the small gap.

[0015] When you want the wheels of the vehicle to move from the basic rail to the movable rail, and If you want to transfer from the side to the basic rail, the movable rail should be tightly attached to the side of the basic rail. Since they are turned so that they are in contact with each other, the tip of one hot air outlet is closed. The hot air that is blown out will heat up the side surfaces of each rail and the sliding plate below. In addition to preventing freezing, it also prevents snow from accreting on the above areas during snowfall. At the same time, the snow is melted to prevent snow from forming.

[0016] In addition, hot air is blown out in the direction where the movable rail and the basic rail are expanded. It works to heat the side surfaces of these rails and raise the ambient temperature.

Next, an example of this invention will be explained with drawings. The electric heater 1 in which a sheathed wire is installed is connected to the A hot air tunnel 2 is formed by covering and molding, and at one end of the hot air tunnel 2, for example, a sirocco fiber is installed. The outlet of the blower 3 which is equipped with a hot air tunnel is connected to the outlet of the blower 3, and the other end is connected to the outlet of the blower 3 which has a In the direction perpendicular to the extension line of the These ventilation tunnels 4 and the hot air tunnel 2 are connected to form a T-shape in plan view. It is something that can be achieved.

[0018] Also, on the side wall of one side of the ventilation tunnel 4, there is a Directing portions 4b are provided to distribute hot air to the left and right discharge ports 4a.

[0019] The present invention configured in this way has a structure that is connected to and separated from the inside of the basic rail 10 as shown in the figure. The rail 10 and the movable rail are placed in the gap 14 between the movable rail 11 having a sharp tip and the rail 10. The rail 11 and the ventilation tunnel 4 are arranged in parallel, and the hot air tunnel 2 is located below the rail 10. The hot air discharged from the outlet 4a of the ventilation tunnel 4 is directed in the direction of arrow c. The movable rail 11 has a sliding plate 1 fixed to the upper surface of the sleeper 12. 3 on the basis of a turning action, these, the rail 10, the movable rail 11 and sliding plate 13 to prevent them from sticking due to freezing. By raising the ambient temperature, snow can be prevented by melting at the same time as snowfall. It has been made possible.

[0020]

[Effect of the idea]

As mentioned above, this device is used to prevent freezing of rails and to prevent snow accumulation during snowfall. The heat source expected to produce the heating effect is the heat generated by an electric heater, and this heat is transferred through air as a medium. As a result, the main parts of the rail, movable rail, and sliding plate are heated using heated gas. In addition, since it increases the temperature of the atmosphere in the above-mentioned important parts, the heating effect is highly effective. It is an effective material that can be used for high efficiency, and when the heat source is the combustion of white kerosene, There is a great synergistic effect by eliminating all human labor.
