[0022]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a vehicle for removing snow and melting snow according to the present invention will be described with reference to the drawings.

In this embodiment, as shown in FIGS. 1 and 2, there is shown a railway vehicle traveling on a traveling surface R composed of rails.

In this embodiment, a vehicle body 2 is mounted and supported on a carriage 1 traveling on a traveling surface R, and the carriage 1 is driven by a diesel engine or the like.

A driver's seat 3 and a power unit 4 such as a diesel engine are arranged at the front of the vehicle body 2. A snow plow 5 is provided at the front of the front part of the vehicle body 2 so that the snow S accumulated on the running surface R can be shunted and removed on both sides.

At the rear of the vehicle body 2, a heated air injection mechanism 6,
The turning mechanism 7 and the injection nozzle 8 are mounted.

The heated air injection mechanism 6 is, for example, an air inlet 6a opened at the upper part of the vehicle body 2 for taking in air A, and a gas turbine for heating the air A taken in from the air inlet 6a and jetting it as a jet stream. 6b and a gas turbine 6b
And a secondary air intake passage 6d for controlling the speed of the jet flow jetted from the nozzle.
Since various types of gas turbines 6b are provided which have a high degree of completeness of mounting on a vehicle or the like having a compact fuel system, cooling system, lubrication system, etc., it is possible to mount a gas turbine 6b having a considerably high capacity. . Note that the control operation of the heated air injection mechanism 6 is performed from the driver's seat 3.
Although not specifically shown, the air inlet 6a can be opened on any surface except the bottom of the vehicle body 2, specifically, on the side, front, and the like. The phone is not specified.

The turning mechanism 7 is connected between the heated air injection mechanism 6 and the injection nozzle 8, and has a function of turning the injection nozzle 8 vertically and horizontally by hydraulic control, electric control or the like. I have. The control operation of the turning mechanism 7 is performed from the driver's seat 3 or an arbitrary place in the vehicle body 2.

The injection nozzle 8 is connected to the turning mechanism 7 and protrudes rearward from the rear part of the vehicle body 2. The injection nozzle 8 can direct the heated air G injected at high speed from the heated air injection mechanism 6 to the running surface R. I can do it.

Further, in this embodiment, a camera 9 such as a CCD camera or an ITV for imaging the periphery of the heated air G injected from the injection nozzle 8 at a high speed, and a camera 9 such as an ITV, Lighting lamp 10 is provided. Note that the camera 9 is connected to a monitor 11 installed in the driver's seat 3.

Further, in this embodiment, a clamp 12 which can be locked to the running surface R is provided at a rear portion of the vehicle body 2.

As shown in FIG. 4, the heating air injection mechanism 6 is driven while performing the snow removal operation shown in FIG. 3, and high-speed injection of the heating air G from the injection nozzle 8 to the running surface R is performed. The snow removal that blows or melts the snow cover S on the uneven portion of the running surface R can be performed. In this snow removal operation, since the heated air G is a jet flow generated by the gas turbine 6b of the heated air injection mechanism 6, the snow cover S can be blown off or melted quite strongly. Then, the snow removal work from the driver's seat 3 is monitored by the camera 9 and the monitor 11 to control the heating air injection mechanism 6 (the damper 6c, the secondary air intake path 6d) and the turning mechanism 7, thereby
By finely adjusting the injection direction of the heated air G, it is possible to reliably blow off and melt the snow S without remaining in the concave portion of the running surface R.

In the snow removing operation shown in FIG. 4, since the air intake 6a of the heated air injection mechanism 6 is opened at the upper part of the vehicle body 2, it is removed on both sides of the running surface R when the air A is taken in. The snow S that has collected is not sucked, and the performance of the heated air injection mechanism 6 does not deteriorate due to the snow S. However, it is also possible to provide the air intakes 6a on the side and front surfaces of the vehicle body 2 within a range not affected by snow. Also, the heated air G
Is a powerful jet flow, which can assist the running power of the vehicle.

When the heated air injection mechanism 6 is driven to inject the heated air G from the injection nozzle 8 to the running surface R, the vehicle body 2 does not start to move due to the reaction force of the heated air injection, and a portion of the running surface R having a concave portion is concentrated. You can also remove snow.

As described above, in addition to the illustrated embodiment, although not particularly shown, the present invention is applied to a vehicle with tires running on a general road. More specifically, a tire hole is provided in place of a bogie, so that it can be used on a general road. Snow removal is also possible.

The following effects can be obtained.

The snow removing snow melting vehicle according to the present invention is capable of injecting heated air to the uneven surface of the running surface to blow up the snow cover to melt the snow and to carry out the snow melting operation widely and inexpensively by accompanying the running. Since the present invention can be implemented, there is an effect that snow can be completely removed from the concave portion of the running surface over a wide range at low snow removal cost.

Further, since the snow is not sucked in when the air is taken in, the performance of the heating air injection mechanism is not reduced by the snow.

Further, in the third aspect, since the heated air to be jetted becomes a jet stream, the force for blowing off or melting the snow is increased, and there is an effect that the snow removing and melting performance is enhanced.

Further, since the injection direction of the high-speed heating air is variable, there is an effect that the snow in the concave portion of the running surface can be reliably removed and melted.

Furthermore, since the snow-melting operation can be monitored from the driver's seat, there is an effect that the snow accumulation in the concave portion of the running surface can be surely removed.

Further, as in the sixth embodiment, there is an effect that it is possible to carry out the snow removal in which the snow accumulated on the running surface is separated and removed on both sides as in the conventional example.

Further, since the movement of the vehicle body can be prevented by the clamp to remove snow and melt the snow,
There is an effect that it is possible to intensively remove snow from a portion having a concave portion of the running surface.
