Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a snow shoveling device for a monorail car used for shoveling snow from the upper surface of a track girder of a mo/rail car.

[Background of the invention]

Conventional snow shoveling devices used for monorail cars either move snow from the top of the track girder to the bottom of the track by transferring rotating brushes to the front of the vehicle, or arrange multiple arrow-shaped brushes. It was caused to fall on both sides of the track girder.

These conventional methods have the disadvantage that the snow scraped from the elevated track falls onto the roadway or pedestrian path on the ground side, and in the case of a short curved track, it is not possible to shovel snow from the entire track girder.
In addition, there was a problem in that the snow that was shoveled accumulated in the skirt around the bogie due to the wind pressure while traveling, making it difficult to maintain the safety of the overhead wires laid on the sides of the track girder. On the other hand, in recent years, monorail car tracks have often been installed on general roads for urban transportation, and in this case, it is considered a problem from a pollution perspective to allow snow on the elevated tracks to fall onto the roadway or pedestrian side rather than onto the support pillars. It will be done. [Objective of the Invention] In view of the above-mentioned problem, the present invention makes snow removal always fall in a fixed direction on the support side, and also makes the snow removal angle of the snow shovel variable depending on the amount of snow or snow quality, thereby achieving more accurate snow removal. The purpose is to cause snow to fall onto the pillar side.

[Embodiments of the invention]

An embodiment of the present invention will be described based on the drawings.

Figure 1 shows the snow shoveling device of the present invention installed on a seat-type monorail car, where 1 is the car body, 2 is the skirt,
3 is a truck, 4 is a snow shovel, 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 snow shoveling device 4.
7 is a tight coupling with a vertical pin 8 that can swing left and right, and a snow shovel 4 is attached to the end of the connector.
are fixedly connected. The close coupling 7 is of a general type, and its fixed connection with the snow shoveling device 4 is the same as that of common couplings. The snow shoveling device 4 is provided with a vertical movement cylinder 18 so that a plurality of snow shoveling brushes 13 can move up and down with respect to the fixed frame 9, and also includes an oscillating cylinder that makes the snow removal angle Q of the brushes 13 variable. 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 has a toothbrush-like shape with a diameter of 3 to 6 ribs, and its tip is bent to prevent snow from scattering in the anti-snow removal direction. There is.
The brush 13 is screwed to a holding frame 14 fixed to a slide frame 19, and the slide frame 19 and fixed frame 9 are connected by each of the cylinders 17, 18 and a hinge 21.
16 is a cylinder support beam having an elongated rod coupling hole, and 22 is a guide.

Arms 0 are provided on both sides of the fixed frame 9 and extend toward the center of the track girder, and a guide wheel 11 and a snow removal plate 12 are provided on the lower surface of the arm 10.
is installed.

15 is a body support that supports the close coupling 3; 20 is an air hose that supplies control air to the cylinders 17 and 18; 23;
is a fair coupling.

The operation of the snow shoveling device having the above configuration will be explained.

In the case of a pedestal type monorail car, if it runs with a large amount of snow on the top of the track girder, it may cause damage because it has high-voltage overhead contact lines on the side of the track girder and the vehicle structure wraps around the contact line. This is unfavorable from a safety standpoint, and in the case of urban transportation, there is also the problem of adhesion in snowy conditions due to the large ups and downs of the track. Therefore, in order to keep the upper surface of the track girders clear of snow, it is necessary to remove snow before the start of commercial operation or by some of the commercial operators. 4 is attached. The brush 13, the holding frame 14, and the slide frame 19 move up and down as a unit, and when shoveling work is not required, the pressurized air from the vertical movement cylinder 18 is discharged and the brush 13 is raised to a predetermined position. put.

When shoveling snow, pressurized air is supplied to the vertical movement cylinder 18 and the brush 13 is brought into contact with the track girder 6a as shown in the figure.

In that case, it is necessary to change the snow removal angle Q of the brush 13 depending on the snow quality, and the angle is adjusted by operating the swing cylinder 17 using the hinge 21 as a fulcrum. Next, the centering action of the snow shoveling device 4 on the short curved trajectory will be explained.

FIG. 4 shows the relationship between the curved track 24 and the snow shoveling device 4, where 0 is the center of the bogie. The bias amount 6 is 6=1
1 (Since it is Moni, the minimum curve radius on the B City monorail car track is 5 sails and the vehicle specification value is about 61,155 mists.

This value is large compared to the 85 m in the orbit, and therefore a centering action is required. For this reason, guide wheels 11 are provided that sandwich both sides of the track girder 6a, so that the snow shoveling device 4 is always located approximately at the center of the track girder 6a. This centering action is possible because the snow shoveling device 4 is fixedly connected to the tight coupling 3 and rotated about the vertical pin 8. Note that the snow removal plate 12 prevents snow from accumulating inside the skirt 2. Although the above explanation has been made with reference to the use in combination with a close coupling, the present invention is not limited to this method, and mounting arms similar to those of a coupling with vertical pins may be provided on the underside of the vehicle underframe. It may also be aligned with the snow shoveling device 4.

〔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, snow can always fall in the center of multiple tracks (support side), there is less risk to vehicles on the ground or passersby, and the snow removal brush can be adjusted depending on the snow quality. Snow removal angle can be changed. 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.
