Description

[Detailed Description of the Invention] The present invention relates to a snow melting device for a railway vehicle, and more particularly to a snow melting device for a railway vehicle that melts and removes snow adhering to the bogie of a vehicle at a railway depot or the like by sprinkling water.

Generally, snow adheres to the bogies of railroad cars that travel in areas with heavy snowfall, and when inspection and maintenance are performed at a depot or the like, the snow adhering to the bogies is first removed.

Conventionally, when removing snow from a trolley, workers sprayed water with a hose and scraped off the snow with a shovel or stick, but this method requires a large number of hands and takes a long time. There is. Therefore, recently, a group of nozzles that spray hot water have been fixedly installed below the rails of the depot, and water is sprayed from this group of nozzles toward the underside of the bogies of vehicles to melt and remove the snow that has adhered to the bogies. things are being done. However, in the case of this conventional snow melting equipment, the nozzle group is fixedly installed, so it is necessary to construct fixed piping, which increases the equipment cost. The disadvantage is that it is not possible to pass under the bridge, which hinders inspection and maintenance.

The purpose of this invention is to provide a snow melting device for railway vehicles that overcomes the drawbacks of the prior art, allows for easy snow melting work, does not cause any hindrance to inspection and maintenance after the snow has melted, and can reduce equipment costs.

This invention melts snow by installing a group of water spray nozzles in parallel on a movable platform, moving the platform and inserting it under the bogie of the vehicle, and spraying water from the nozzle group on both sides of the wheels of the bogie. After the snow melts, the movable platform can be moved from under the truck, allowing inspection and maintenance work to be carried out without any hindrance.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3 showing an embodiment of the present invention, a handcart 1 serving as a moving platform has a suitable number of wheels 2.
and a handle 3, so that it can be moved freely on the floor of a railway depot or the like. A main pipe 4 through which hot water can flow is fixed to the upper surface of the handcart 1, and the main pipe 4 is connected to a hot water supply source (not shown) via a flow control valve 5 and a hose 6. A pair of standpipes 7A, 7B are branched from the front and rear of the main pipe 4 and stand up almost at right angles to the top surface of the handcart 1, and at the upper ends of the pair of standpipes 7A, 7B are headers 8A, 7B.
8B are connected to the handle 3 of the handcart 1 substantially parallel to each other. The headers 8A, 8B are respectively provided with a plurality of nozzle groups 9A, 9B arranged at approximately equal intervals in the longitudinal direction of the header. One nozzle group 9B is set so that its water spraying direction is approximately within a vertical plane, and the other nozzle group 9A is set such that its watering direction is approximately within a vertical plane and tilted forward with respect to the vertical plane. The nozzle group 9
Both A and 9B are designed to spray hot water upward. Further, a pair of stoppers 10, 10 are installed at approximately the center of both ends of the handcart 1, standing up at approximately right angles.

In addition, in FIG. 2 and FIG. 3, 11 is the foundation in the railway depot, 12 is the beam constructed on the foundation 11, 13 is the rail laid on the beam 12, 14 is the bogie of the vehicle, 15 is a cart wheel, 1
6 is the body of the vehicle, and 17 is a drainage pit dug between the rails 13, 13.

The method of use and operation of the snow melting device for railway vehicles according to the above configuration will be explained.

First, the handcart 1 is moved using the handle 3, and as shown in FIG. 2 and FIG.
1, directly below the beam 12. At this time, the stopper 10 of the handcart 1 is set to the beam 1.
2, the handcart 1 can be easily positioned, and the wheels 2 of the handcart 1 are prevented from falling into the pit 17. This positioning of the handcart 1 causes the pair of nozzle groups 9A and 9B to spray water toward both sides of one wheel and toward the inner surface of the other wheel, as shown in FIG. Next, when the flow rate control valve 5 is opened, hot water flows from the hot water supply source to the hose 6, the control valve 5, the main pipe 4,
The water is injected from the nozzle groups 9A, 9B through the standpipes 7A, 7B and the headers 8A, 8B, and is sprayed on both sides of one wheel 15 and toward the inside of the other wheel 15. With this watering, one wheel 1
The snow adhering to both sides of the wheel 5 and the inside of the other wheel 15 melts and is naturally removed. next,
The wheelbarrow 1 is connected to the beam 12 on which the other wheel 15 is located.
Insert it directly below the wheel and sprinkle water in the same way as above to melt snow from both wheels. By the way, experiments have shown that it is possible to completely remove snow by sprinkling water for about 10 minutes.

According to this embodiment, since the movable platform is constituted by a handcart, the structure is simple, and equipment costs and maintenance costs can be kept extremely low.

In the above embodiment, the mobile platform is configured as a handcart and the worker pushes the wheelbarrow to move it, but the mobile platform is configured to move automatically by mechanical force. It is easy to fully automate the process to save labor or make it unmanned. Further, in the embodiment, the control valves are attached to the main pipe side, but they may be provided to each header so that the pair of nozzle groups can spray water independently from each other.

As explained above, according to the present invention, a nozzle group is provided on the movable platform, and snow adhering to the underside of the vehicle is melted and removed by water sprinkling from the nozzle group, making snow melting work easier and By moving the movable platform, it is possible to avoid interfering with inspection and maintenance work after the snow melts.
