Description

本発明は、前部に設けたロータリ除雪装置と、進行方向に斜めに向いて前記ロータリ除雪装置に雪を案内する左右の掻き寄せ翼とを備え、軌道上を走行するロータリ除雪車に関する。 The present invention relates to a rotary snowplow that travels on a track, including a rotary snowplow provided at the front, and left and right scraper blades that are inclined obliquely in the traveling direction and guide snow to the rotary snowplow.

従来、この種のロータリ除雪車として、ロータリ除雪装置が前端部に設けられ、回転駆動されて積もった雪を切削し中央に掻き寄せるオーガと、このオーガの背面の周面を囲う除雪枠と、この除雪枠の後方に設けられ、上記オーガによって取り込まれた雪を側方に投雪する投雪用ブロアによって構成され、前記ロータリ除雪装置の前側には左右のウイングが、その後端部のヒンジ部を除雪枠に支持されて該ヒンジ部を中心に回転自在に設けられ、また、それら左右のウイングは、油圧シリンダ（図示略）により操作されて、上方あるいは下方のいずれかの位置に配されるようになっており、除雪車が進行すると、左右のウイングにより雪が除雪装置に案内される（例えば特許文献１）。 Conventionally, as this type of rotary snowplow, a rotary snowplow is provided at the front end, an auger that cuts and accumulates the snow that is rotated and driven, and a snow removal frame that surrounds the peripheral surface of the back of the auger, The snow removing blower is provided behind the snow removing frame and projects the snow taken in by the auger to the side. Left and right wings are provided on the front side of the rotary snow removing device, and a hinge portion at the rear end thereof. The left and right wings are operated by a hydraulic cylinder (not shown) and arranged at either the upper or lower position. As the snowplow advances, snow is guided to the snow removal device by the left and right wings (for example, Patent Document 1).

ところで、上記のような従来のロータリ除雪車は、ウイングを昇降する機構を備えるものの、軌道の上面より低い位置の除雪は行われていなかった。 By the way, although the conventional rotary snowplows as described above have a mechanism for raising and lowering the wing, snow removal at a position lower than the upper surface of the track has not been performed.

そこで、公知ではないが除雪のためにウイングを軌道の高さ位置より下げた場合、以下のような問題が生じる。 Therefore, although not known, when the wing is lowered from the height position of the track for snow removal, the following problems occur.

図１７〜図１８は上記ウイングに相当する掻き寄せ翼を備えたロータリ除雪車の一例を示し、このロータリ除雪車は鉄道の軌道上を走行し、前部左右に掻き寄せ翼101，101を備え、この掻き寄せ翼101は、ヒンジ部102を中心に回動自在に設けられ、縦方向の翼本体103と、この翼本体103の下縁を前側の折り曲げるように傾斜して設けた雪掻き面部104とを備え、前記掻き寄せ翼104を上下させて軌道の高さ位置より低い位置で除雪をすることによって、従来よりロータリ除雪装置の除雪面積を大きく取ることができる。 FIGS. 17 to 18 show an example of a rotary snowplow having a scraping blade corresponding to the wing. The rotary snowplow runs on a railroad track and has scraping blades 101 and 101 on the front left and right. The scraping blade 101 is provided so as to be rotatable about the hinge portion 102, and the snow blade surface portion 104 is provided so as to bend so that the longitudinal edge of the blade body 103 and the lower edge of the blade body 103 are bent forward. And removing the snow at a position lower than the height of the track by moving the scraping blade 104 up and down, it is possible to increase the snow removal area of the rotary snow removal device.

特開平６−１５８６２１号公報JP-A-6-158621

上記図１７〜図１８のロータリ除雪車が除雪の際、進行すると、前方の雪が左右の掻き寄せ翼101，101により前部の除雪装置に掻き寄せられる。そして、効率よく除雪するために、掻き揚げ面部104にすくい角θ（掻き揚げ面部104が垂直に対して前方に傾斜した角度）を設けているため、掻き寄せ翼101が通過した後の残雪105の断面形状が、段差を有する除雪工法の場合、鋭角な段差部106となる。この段差部106の角度は掻き寄せ翼101の前記ヒンジ部101を中心した開き角度によって変化するが、掻き寄せ翼101が９０度に開いた場合を除いて、残雪105には側面が削り取られたような段差部106が形成される。 When the rotary snowplow in FIGS. 17 to 18 progresses during snow removal, the forward snow is scraped to the front snow removal device by the left and right scraping blades 101, 101. In order to remove snow efficiently, the scraping surface portion 104 is provided with a rake angle θ (an angle at which the scraping surface portion 104 is tilted forward with respect to the vertical direction), so that the remaining snow 105 after the scraping blade 101 has passed through. In the case of the snow removal method in which the cross-sectional shape is a step, the stepped portion 106 is an acute angle. The angle of the stepped portion 106 changes depending on the opening angle of the scraping blade 101 around the hinge portion 101, but the side surface of the remaining snow 105 was scraped except when the scraping blade 101 was opened at 90 degrees. Such a step 106 is formed.

そして、前記鋭角な段差部106を有する残雪105は、除雪車が通過する際の衝撃や巻き込み風などによって崩れ易く、このため除雪後の残雪105の段差部106が多くの場所で崩落し、掻き寄せ翼101が除雪した跡に、雪の塊を落とすことになり、綺麗な仕上がりが得られないという問題が生じることが予想される。 Further, the remaining snow 105 having the sharp stepped portion 106 is liable to collapse due to an impact or a wind when the snowplow passes, and therefore, the stepped portion 106 of the remaining snow 105 after snow removal collapses in many places and scrapes. A lump of snow will be dropped on the trace of the wing 101 that removed snow, and it is expected that there will be a problem that a beautiful finish cannot be obtained.

そこで、本発明は上述した問題点に鑑み、残雪における鋭角な段差部の発生を防止し、綺麗な仕上がりが得られるロータリ除雪車を提供することを目的とする。 Therefore, in view of the above-described problems, an object of the present invention is to provide a rotary snowplow that can prevent a sharp stepped portion from remaining snow and obtain a beautiful finish.

図３及び図４に示すように、前記翼本体11の内側には上下に連結腕部31，31を設け、これら連結腕部31，31を前記ヒンジ軸８に回動可能で且つ昇降可能に連結している。また、上側の連結腕部31に略コ字片の昇降体32を一体に設け、この昇降体32の上部32Ａと下部32Ｂに前記ヒンジ軸８を挿通して該ヒンジ軸８に昇降体32を昇降自在に設け、この昇降体32の上部と前記除雪装置２とに駆動手段たる油圧シリンダ33の上下を連結し、この油圧シリンダ33の伸縮により前記翼本体11がヒンジ軸８に沿って昇降し、これにより前記翼本体11が昇降し、前記昇降体32及び油圧シリンダ33により昇降駆動手段34を構成している。 As shown in FIG. 3 and FIG. 4, connecting arm portions 31, 31 are provided on the inside of the wing body 11, and the connecting arm portions 31, 31 can be rotated about the hinge shaft 8 and can be moved up and down. It is connected. Further, a substantially U-shaped lifting body 32 is integrally provided on the upper connecting arm portion 31, and the hinge shaft 8 is inserted into the upper portion 32 A and the lower portion 32 B of the lifting body 32 so that the lifting body 32 is attached to the hinge shaft 8. The upper and lower parts of the lifting / lowering body 32 and the snow removal device 2 are connected to the upper and lower sides of a hydraulic cylinder 33 which is a driving means, and the wing body 11 is lifted and lowered along the hinge shaft 8 by the extension / contraction of the hydraulic cylinder 33. As a result, the wing body 11 moves up and down, and the elevating body 32 and the hydraulic cylinder 33 constitute the elevating drive means 34.

一方、前記固定翼10は前記翼本体11の半分程度の高さを有し、その固定翼10は、ヒンジ軸８に高さ固定連結腕部35により高さ位置が固定可能で、且つ前記翼本体11と同体的に回動可能に設けられている。尚、高さ固定連結腕部35は、ヒンジ軸８の所定位置に高さ位置固定可能に設けられ、その高さ位置を調整することができ、後述するように固定翼10の下縁10Ｆにより、除雪後の残雪の上面が形成される。 On the other hand, the fixed wing 10 has a height about half that of the wing body 11, and the fixed wing 10 can be fixed at a height position to the hinge shaft 8 by a height fixing connecting arm 35, and the wing The main body 11 and the main body 11 are provided so as to be rotatable. The fixed height connecting arm portion 35 is provided at a predetermined position of the hinge shaft 8 so that the fixed height position can be fixed, and the height position can be adjusted. As will be described later, the fixed wing 10 has a lower edge 10F. The upper surface of the remaining snow after snow removal is formed.

次に、前記構成につきその作用を説明する。左右の翼寄せ翼７，７を進行方向に対して角度θｙが約４５度になるように開いて固定し、昇降駆動手段34により、雪掻き板部12の下縁が軌道３の上面より低くなる位置に高さ固定し、ロータリ除雪装置２を駆動して走行すると、雪が左右の翼寄せ翼７，７により集められ、ロータリ除雪装置２のブロア６により軌道３の外側に吹き飛ばされる。そして、図１０に示すように、左右の翼寄せ翼７，７により掻き寄せられた後の残雪18の段差部19は、その上面19Ａが固定翼10の下縁10Ｆにより水平に形成されると共に、その側面19Ｂが雪掻き縁部14によりほぼ垂直に形成される。このように段差部19に鋭角な角部が形成されないため、除雪の後が綺麗なものになる。 Next, the effect | action is demonstrated about the said structure. The right and left blades 7 and 7 are opened and fixed so that the angle θy is about 45 degrees with respect to the traveling direction, and the lower edge of the snow scraping plate portion 12 becomes lower than the upper surface of the track 3 by the lift drive means 34. When the height is fixed at the position and the rotary snow removal device 2 is driven to travel, the snow is collected by the left and right blade wings 7, 7 and blown off to the outside of the track 3 by the blower 6 of the rotary snow removal device 2. Then, as shown in FIG. 10, the stepped portion 19 of the remaining snow 18 after being raked by the left and right blade wings 7, 7 has its upper surface 19 A formed horizontally by the lower edge 10 F of the fixed wing 10. The side surface 19B is formed substantially vertically by the snow scraping edge portion 14. As described above, since the sharp corner portion is not formed in the stepped portion 19, it becomes beautiful after snow removal.
