Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a snow plow device for a mole seal car using a snow plow V on the upper surface of a track girder of a mole rail force.

[Background of the invention]

In the conventional snow inspection device used for mole rail cars, a rotating brush is rolled on the head of the vehicle to cause the snow on the upper part of the track girder to fall one step below the track.
A plurality of arrow-shaped brushes were arranged and dropped on both sides of the track girder. Are these conventional roadways or pedestrian roads on the ground side of the elevated tracks? In addition to the x point at which the snow that has been scraped falls falls, in the case of a short curve track, the snow can be trapped throughout the track phase, and the snow that has been snagged can accumulate in the skirt around the bogie due to wind pressure while traveling. However, there was a problem in that the safety of the overhead wires laid on the side of the track girder was not maintained. On the other hand, in recent years, railcar tracks have often been installed on general roads for urban transportation, and public documents state that snow on the elevated tracks should fall on the roadway or pedestrian side instead of on the support pillars. This is considered a problem.

[Purpose of the invention]

In view of the above-mentioned problems, the present invention makes the snow removal always fall in a fixed direction on the support column side, and also changes the snow removal angle of the thunder hook flage depending on the snow thickness or snow quality. However, the purpose of this invention is to make lightning fall on the pillar side in a more targeted manner. [Embodiment of the Invention] An embodiment of the present invention will be described with reference to Figure t.

Figure 1 shows the snow shoveling device of the present invention installed on a mole railcar e.
1 is a car body, 2 is a skirt, 3 is a trolley, 4 is a snow bag layer, and 5 is a support. The figure shows an example of a double track track, where 6a is a track girder for the up line, and 6b is a track girder for the down line.

Figures 2 and 3 show the configuration of the snow plow device. 7 is a close coupling with a vertical pin 8 that can swing from side to side, and its end t is fixed by the snow plow device doctor. be combined. The above-mentioned close coupling 7 is of a general type, and the fixed coupling with the snow-making device ± is the same as the coupling between common couplings. The snow shoveling device is provided with a vertically movable cylinder 18 so that a plurality of snow shoveling planes 13 can move up and down relative to a fixed frame 91, and also has an oscillating cylinder that makes the snow removal angle σ of the brush 13 variable. One cylinder 17 is provided between the fixed frame 9 and the slide frame 19. The material of the brush 13 is, for example, flexible plastic, and a toothbrush-shaped toothbrush with a diameter of 3 to 6 mm is embedded in the brush 13, and its tip is bent to prevent snow from scattering in the direction of snow removal. ing. brush 1

is a cylinder support beam with an elongated rod connection hole;
22 is a guide.

Arms 10 are provided on both sides of the fixed frame 9 and project out toward the center of the track girder, and a guide wheel 11 and a snow removal plate 12 are attached to the lower surface of the arm 10. 15 is a side support that supports the close coupling 3; 20 is an air hose that supplies control air to the cylinders 17 and 18; and 23 is an air coupling.

The above configuration? The function of the snow shoveling device will be explained.

In the case of a mole rail car, when running with heavy snow on the top of the track girder, the side of the track girder has a high-voltage overhead line, and the vehicle structure wraps around the overhead line. This is not desirable in terms of safety, and in the case of urban transportation, the track has a large undulating gradient, which causes problems with adhesion in snowy conditions. Therefore, in order to ensure that there is no snow on the upper surface of the track girder, it is necessary to remove snow before the start of commercial operation or on some of the commercially operated vehicles. This is to attach the lightning hook device 4.

Brush] 3. The holding frame 14 and the sliding frame 9 move up and down as a unit, and when the snow plowing operation is not required, the pressurized air from the vertical movement cylinder 18 is discharged and the brush 3 is moved up and down to a predetermined position. I'll let you.

When shoveling snow, pressurized air is supplied from the vertical cylinder 18 to move the brush 13 to the track girder 6a as shown in the figure.
Drive in contact with the In that case, depending on the snow quality, it is necessary to change the snow removal angle σ of the brush 13, making the hinge 2] the fulcrum. The angle is then adjusted by operating the swing cylinder 17.

Next, the centering effect V on the short curved trajectory of the snow shovel i4 will be explained. FIG. 4 shows the relationship between the curved track 24 and the lightning gear [4], where 0 is the center of one bogie.

Based on the minimum curve radius of 50 m on the city mall track and the vehicle specification value, it will be about 550 m in δ.

This value is large compared to 850n during the orbital phase, and therefore a centering action is required.

For this reason, guide wheels 1 which are sandwiched between both sides of the track girder 6a are provided so that the snow plowing device 4 is always positioned substantially in the center of the track girder 6a. This centering effect is
This is possible by fixing the snow shovel body to the tight coupling 3 and rotating it around the vertical pin 8. Incidentally, the snow removal plate 12 prevents lightning from accumulating inside the skirt 2.

Although the above explanation has been made with reference to the use in combination with a tight coupler, the present invention is not limited to this method. It may be installed and combined with a lightning scratcher doctor.

〔Effect of the invention〕

Since the present invention is as described above, it has the following effects. In other words, the direction of snow removal is constant,
It is possible to always remove snow from the center (support side) of multiple tracks, reducing the risk of hitting vehicles or passersby on the ground side, and change the snow removal angle of the snow removal brush depending on the snow quality. I can do it. In addition, the snow removal effect on the upper surface of the minimum curve track is high, and it is possible to prevent falling snow from accumulating inside the skirt.
