Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a snow removal device for preventing snow accumulation on a beam constructed so as to cross over a railway line in order to support a train line.
[0002]
[Prior art]
If snow piled up on the railroad track beam falls on a train passing underneath, it may interfere with driving. Conventionally, as a measure for removing snow accumulated on the beam, it has been practiced to apply a paint that does not easily adhere to the snow, or to attach a roof-like inclined plate on which the snow easily slides down.
[0003]
[Problems to be solved by the invention]
The conventional snow removal countermeasures by painting are easily affected by the shape of the beam, snow quality, temperature, etc., and a sufficient effect cannot be expected. The inclined plate may cause snow on the slope to fall at a time and still affect the running of the train. Accordingly, an object of the present invention is to provide a snow removal device that operates when there is a predetermined amount of snowfall and efficiently removes snow on a beam.
[0004]
[Means for Solving the Problems]
In the present invention, in order to solve the above-described problem, the electric fan 1 disposed on the beam B with the air blowing direction directed to the extending direction of the beam B, and the snowfall amount sensor 2 for detecting the amount of snowfall per unit time. A temperature sensor 3 that detects the outside air temperature, and a control device that receives the detection signals from the snowfall amount sensor 2 and the temperature sensor 3 and operates the fan 1 when a snowfall amount that is greater than a set value and an outside air temperature that is less than the set value are detected. 4 and configured to remove the snow accumulated on the beam B with the wind force of the fan 1 to remove the beam for the railway track.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. 1 is a front view of the snow removal device, FIG. 2 is a side view of the snow removal device, and FIG. 3 is an explanatory view of the snow removal device.
[0006]
In FIG. 1 and FIG. 2, a beam B that horizontally traverses over the railroad track is supported by a column P. On the beam B, an electric fan 1 having a capacity for generating sufficient wind power to blow off snow on the beam is attached. A single fan or a plurality of fans 1 are arranged depending on the length of the beam B so that the blowing direction is directed to the extending direction of the beam B. When attaching a plurality of fans, it is convenient not to make adjacent fans face each other. If necessary, the fan 1 can be swung.
[0007]
A snowfall amount sensor 2, a temperature sensor 3, and a control device 4 are attached to the column P. As shown in FIG. 3, the snowfall amount sensor 2 optically detects the amount of snowfall (number of raindrops) per unit time and sends a detection signal to the control device 4. The temperature sensor 3 detects the temperature of the outside air and sends a detection signal to the control device 4. The control device 4 receives the detection signals from the snowfall amount sensor 2 and the temperature sensor 3, and the amount of snowfall above the set value and the outside air temperature below the set value, for example, the snowfall count is 60/2 min. Is detected, the fan 1 is operated. 5 is a temperature controller. The fan 1 starts and stops repeatedly according to snowfall.
[0008]
Therefore, the snow removal device starts and stops the fan 1 in a timely manner, blows off the snow falling on the beam B, and prevents snow accumulation.
[0009]
【The invention's effect】
As described above, in the present invention, the electric fan 1 disposed on the beam B with the blowing direction in the extending direction of the beam B, the snowfall amount sensor 2 for detecting the snowfall amount per unit time, A temperature sensor 3 that detects the outside air temperature, a control device 4 that receives the detection signals from the snowfall amount sensor 2 and the temperature sensor 3 and operates the fan 1 when a snowfall amount that is greater than a set value and an outside air temperature that is less than the set value are detected; Since the snow removal device for the railroad track beam is configured to blow off the snow accumulated on the beam B by the wind force of the fan 1, the snow accumulation on the beam B is efficiently and reliably prevented, and the train It has the effect that the safety of operation can be ensured.
