Abstract

PROBLEM TO BE SOLVED: To save snow-removing work labor by mounting a snow removing plate to a snow collecting side wing of a snowplow through a supporting arm, and making the snow removing plate groundable on a station platform. SOLUTION: A supporting arm 18 of a station platform snow removing device 13 is mounted in a horizontally oscillating state to the tips of lateral closable front side wings 9, provided at a rotary snow removing device of a snowplow, through a first lever 14 and a second lever 15. A snow removing plate is fitted in a vertically elevating state to the arm 18 through parallel link mechanism 25. At the time of removing snow, an oscillating cylinder 21 is contracted to protrude the arm 18 to the edge part of a station platform A, and an elevating cylinder 30 is elongated to lower the snow removing plate 26 and to ground the lower end on the platform A. The snowplow is made to travel to scrape off snow on the platform A on a track by the snow removing plate 26, and the snow is collected by an auger of the rotary snow removing device and thrown into a position out of the way from the track by a blower. Snow can therefore be removed rapidly without manual force, and the conventional snowplow can be utilized at a low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a station platform snow removing device suitable for removing snow that has blown into a railway station yard and falls on a platform.

[0002]

2. Description of the Related Art As is well known, in a snowy country in winter,
The snow that blew into the railway station yard fell on the platform,
When this is crushed and frozen by people getting on and off the train, there is a greater danger of slipping and falling, so that the snow accumulated on the platform is removed, that is, so-called snow removal is performed.

[0003] Conventionally, snow removal work on station platforms is mainly performed manually, and is carried out between train departures and arrivals.

[0004]

However, manual snow removal requires a great deal of labor and time, resulting in extremely poor workability, and the work must be performed efficiently within a short time between train departures and arrivals. In addition, there was a problem that the snowplow was forced to work hard.

[0005] Incidentally, the railway station platform is provided with a roof, from which snow blows into the platform,
Mainly snow falls on the edge of the station platform facing the railway track. Therefore, in order to prevent a slip or a fall due to snow on the platform of the station, it is only necessary to remove snow from the edge of the station platform facing the track.

The present invention has been made based on such a background, and it is an object of the present invention to provide a station platform snow removing device capable of satisfactorily removing snow from a station platform without using human power. Is to do.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a vehicle comprising a left and right openable left and right wings and an auger for snow collection, and a blower for throwing snow collected by the side wings and the auger. Mounted on a tip of the left and right side wings so as to be swingable in a horizontal direction, and a snow removal plate is mounted on the support arm so as to be able to move up and down in a vertical direction. The side wings are provided with swing means for swinging the support arm so as to protrude to the edge of the station platform, and the support arm is provided with elevating means for lifting and lowering the snow removing plate so as to contact the station platform. Provide station platform snow removal equipment.

According to the station platform snow removing device of the present invention, the snow removing plate scrapes the snow accumulated on the station platform along the running of the snow plow onto the railroad track. It can be performed well.

Is mounted on a bracket (31) attached to the support arm (18) so that the tip of the cylinder body (30a) is swingable via a pivot pin (32), and the tip of the piston rod (30b) is attached to the bracket (31). A bracket (33) attached to the snow removal board (26) is swingably mounted via a pivot pin (34). When the elevating cylinder (30) is extended and retracted, the snow removing plate (26) is vertically moved up and down via the parallel link mechanism (25). A cushion (35) made of hard rubber or the like is attached to the lower end of the snow removing plate (26).

Next, the snow removal at the station platform according to the present embodiment having the above configuration will be described.

At the start of snow removal, the snowplow (1) has the front wings (9) of the rotary snow removal device (3) closed so as not to hinder the running, and has an auger (5) and a blower (6). Is driven. In addition, the station platform snow removing device (13) sets the lifting cylinder (30) in a contracted state to raise the snow removing plate (26), and sets the swinging cylinder (21) in an extended state to set the support arm (1).
8) is stored.

In the above state, the station platform snow removing device (1) attached to the front wing (9) on the station platform side where snow is removed is provided.
3) With the swinging cylinder (21) in the contracted state, the support arm (18) is extended to the edge of the station platform (A) (see FIG. 6), and the lifting cylinder (30) is in the extended state to remove snow. By lowering the board (26) (see the imaginary line in FIG. 5), the snow removing board (26) is brought close to the station platform (A) and the cushion (3) attached to the lower end thereof
5) Ground the station platform (A). In this manner, the snow removal board (26) is brought close to the station platform (A), and the cushion (35) attached to the lower end thereof is grounded to the station platform (A). When the vehicle 2 travels, the snow that has accumulated on the station platform (A) is scraped off to the track by the snow removing plate 26 as the vehicle 2 travels. Then, the snow scraped off the track is collected at the center by the auger (5), and is thrown away from the track by a blower (6) provided behind the auger (5). Will be.

As described above, according to this embodiment,
Since the snow removing plate (26) of the station platform snow removing device (13) attached to the snow removing vehicle (1) removes snow from the station platform (A) as the snow removing vehicle (1) travels, without depending on human power. The station platform (A) can be satisfactorily cleared of snow. Therefore, it is possible to speed up the snow removal at the station platform (A), and to significantly reduce the number of snow removal personnel, thereby improving workability. Moreover, since the station platform snow removing device (13) is added to the conventional snow removing vehicle, if the station platform snow removing device (13) is prepared as an attachment, the conventional snow removing device can achieve the above-described effects at low cost. The snow plow (1) can be improved. When the snow removal of the station platform (A) is not performed, the snow removing plate (26) of the station platform snow removing device (13) is raised and the support arm (1) is removed.
8), it is safe even if the snowplow (1) passes through the station platform (A).

[0021]

As described above, according to the present invention,
Since the station platform snow removal device attached to the snowplow removes snow from the station platform using the running operation of the snowplow, the station platform can be snow-removed satisfactorily without human power. In addition, the speed of snow removal can be increased, and the number of snow removal personnel can be significantly reduced, thereby improving workability.
