[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a track anti-freezing device, and more particularly to a track anti-freezing device used to prevent malfunction due to freezing of rail points.

[0002]

2. Description of the Related Art A situation in which a rail point of a railway freezes in the winter and causes an operation failure may lead to a train accident or hinder normal operation of the train. Therefore, conventionally, as a measure to prevent the freezing of the point, the point is heated by pouring hot water or setting up many candles at the point.

[0003]

However, there is a problem in that the above-described measures require human labor but cannot achieve the expected effects.

[0004] The present invention has been made in view of this problem, and is basically based on preventing freezing by spraying warm air on a place where freezing is prevented, for example, by blowing hot air onto the track. Considering various conditions such as being formed by two parallel rails and the need to prevent excessive consumption of electric power when using electric power to generate hot air, It is an object of the present invention to provide a track freezing prevention device that can satisfy the conditions.

[0005]

An orbital freezing prevention apparatus according to the present invention is provided inside a box-shaped case having an outside air suction port.

A pair of the warm air blowing units can be configured by a master unit and a slave unit electrically connected by the energization circuit. .

The orbital freeze prevention device of the present invention is installed near a track with its hot air outlet directed to a place where freezing is to be prevented. At that time, a pair of hot air blowout units (for example, a master unit and a child unit) are provided. ) Are installed separately on each of the two rails. When the orbit prevention device is installed in this way, when the power is supplied to the energizing circuit and the respective hot air blowers of the pair of hot air blowing units are operated, the hot air blown out from the hot air outlets of the hot air blowers is generated. The freezing is prevented by hitting a place where freezing is to be prevented, such as the two rails forming a point or the point switching mechanism. In addition, when the timer controls the energization state of the hot air blower unit to the hot air blower and the energization state of the other hot air blower unit to the hot air blower, wasteful power consumption is suppressed and the operating cost is reduced. .

[0007] The timer may have a function of alternately turning on and off the energized state of the hot air blower unit to the hot air blower and the energized state of the other hot air blower unit to the hot air blower. desirable.

[0008] With this configuration, it becomes possible to alternately operate the hot air blower of one hot air blow-off unit and the hot air blower of the other hot air blow-out unit, so that wasteful power consumption is further increased. At the same time, the orbit prevention device can be operated without difficulty within the range of the allowable power consumption.
