Description

本発明は一般に、圧雪装置に関する。より詳細には、本発明は、道路に降り積もった雪を道路面に押しつけて減容化する（容積を減少させる）ことにより、車両や人の円滑な通行を確保する圧雪装置に関する。   The present invention generally relates to snow compaction devices. More specifically, the present invention relates to a snow pressure device that ensures smooth passage of a vehicle or a person by reducing the volume of the snow that has accumulated on the road against the road surface (reducing the volume).

降雪地帯では、冬期に降り積もった雪を如何にして処理するのかが重要な課題となっている。降雪地帯の地方自治体などは、毎年、莫大な予算を計上して、除雪作業を実施しているが、このような除雪作業は、疲弊した地方自治体の財政にとって、多大な負担となっている。   In snowfall areas, how to deal with snow that has fallen in winter has become an important issue. Local governments in snowfall areas, etc., make a huge budget every year and carry out snow removal work, but such snow removal work is a great burden on the finances of exhausted local governments.

本発明は、このような事情に鑑みて開発されたものであって、道路に降り積もった雪を取り除く（除雪する）のではなく、道路面に押しつけて減容化することにより、円滑な交通を実現する圧雪装置を提供することを目的としている。   The present invention has been developed in view of such circumstances, and does not remove (remove) the snow that has accumulated on the road, but presses it against the road surface to reduce the volume, thereby facilitating smooth traffic. The object is to provide a snow snow device to be realized.

本願請求項１に記載の圧雪装置は、ホイールローダ又はタイヤショベルの車体後部に連結アームを介して回転可能に装着された圧雪機を備え、前記圧雪機が、前記車体後部に連結された連結アームに回転可能に取り付けられたシャフトと、全体としてほぼテーパ状になるように前記シャフトに取り付けられた６個のチェーン付きタイヤとを有しており、前記６個のチェーン付きタイヤが、走行時に最も車道センターライン側に位置する最小径のタイヤの径Ｄ2 が、走行時に最も歩道側に位置する最大径のタイヤの径Ｄ1 の０．４倍〜０．６倍となるように選定され、歩道側から車道センターライン側に向かって徐々に小径になるように選定されていることを特徴とするものである。 A snow pressure device according to claim 1 of the present application includes a snow pressure machine rotatably mounted on a rear part of a vehicle body of a wheel loader or a tire excavator via a connection arm, and the snow pressure machine is connected to the rear part of the vehicle body. And six chain-equipped tires attached to the shaft so as to be substantially tapered as a whole. The diameter D 2 of the smallest diameter tire located on the roadway center line side is selected to be 0.4 to 0.6 times the diameter D 1 of the largest diameter tire located closest to the sidewalk when running, It is selected so that the diameter gradually decreases from the sidewalk side toward the roadway center line side.

本願請求項２に記載の圧雪装置は、ホイールローダ又はタイヤショベルの車体後部に連結アームを介して回転可能に装着された圧雪機を備え、前記圧雪機が、前記車体後部に連結された連結アームに回転可能に取り付けられたシャフトと、前記シャフトに取り付けられ、周面に多数の突起が設けられたローラとを有しており、前記ローラが、走行時に歩道側から車道センターライン側に向かって徐々に小径になるようにテーパ状に形成されていることを特徴とするものである。   According to a second aspect of the present invention, there is provided a snow pressure device comprising: a snow pressure machine rotatably attached to a rear part of a vehicle body of a wheel loader or a tire excavator via a connection arm, wherein the snow pressure machine is connected to the rear part of the vehicle body. A shaft that is rotatably attached to the shaft, and a roller that is attached to the shaft and has a large number of protrusions on the circumferential surface, and the roller moves from the sidewalk side toward the roadway centerline side during traveling. The taper is formed so that the diameter gradually becomes smaller.

本発明の圧雪装置によれば、除雪に比較して低コストで、降雪地帯における冬期間の円滑な交通を確保することができる。また、本発明の圧雪装置は、既存の建設機械（ホイールローダ、タイヤショベル）を利用するため、製造コストや維持管理コストを廉価に抑えることができる。   According to the snow pressure device of the present invention, it is possible to ensure smooth traffic during the winter period in a snowy area at a lower cost than snow removal. In addition, since the snow pressure device of the present invention uses existing construction machines (wheel loaders, tire shovels), manufacturing costs and maintenance costs can be kept low.

次に図面を参照して、本発明の好ましい実施の形態に係る圧雪装置について詳細に説明する。図１は、本発明の好ましい実施の形態に係る圧雪装置を示した側面図、図２は、図１の圧雪装置の平面図である。図１及び図２において全体として参照符号１０で示される本発明の好ましい実施の形態に係る圧雪装置は、ホイールローダ１２の車体後部に連結アーム１４ａを介して回転可能に装着されたテーパ状圧雪機１４を備えている。   Next, with reference to the drawings, a snow snow device according to a preferred embodiment of the present invention will be described in detail. FIG. 1 is a side view showing a snow pressure device according to a preferred embodiment of the present invention, and FIG. 2 is a plan view of the snow pressure device of FIG. 1 and 2, a snow pressure device according to a preferred embodiment of the present invention, indicated as a whole by the reference numeral 10, is a tapered snow pressure machine that is rotatably attached to the rear part of a vehicle body of a wheel loader 12 via a connecting arm 14 a. 14 is provided.

テーパ状圧雪機１４は、連結アーム１４ａに回転可能に取り付けられたシャフト１４ｂと、全体としてほぼテーパ状になるようにシャフト１４ｂに取り付けられた６個のチェーン付きタイヤ１４ｃ1 、１４ｃ2 、１４ｃ3 、１４ｃ4 、１４ｃ5 、１４ｃ6 とを有している（タイヤ１４ｃの個数を６個としたのは、既存のホイールローダの横幅に対応させるためである）。 Tapered compacted snow machine 14 includes a shaft 14b rotatably mounted on the connecting arm 14a, 6 pieces of the chain with the tire 14c 1 that is attached to the shaft 14b so as to be substantially in a tapered shape as a whole, 14c 2, 14c 3 , 14c 4 , 14c 5 , 14c 6 (the number of tires 14c is six in order to correspond to the width of the existing wheel loader).

６個のタイヤ１４ｃ1 〜１４ｃ6 は、圧雪装置１０の走行時に最も車道センターライン側に位置する最小径のタイヤ１４ｃ6 の径Ｄ2 が、圧雪装置１０の走行時に最も歩道側に位置する最大径のタイヤ１４ｃ1 の径Ｄ1 の０．４倍〜０．６倍となるように（すなわち、０．４Ｄ1 ≦Ｄ2 ≦０．６Ｄ1 となるように）選定し、かつ、タイヤ１４ｃ1 からタイヤ１４ｃ6 に向かって徐々に小径になるように選定されている。 Up to six tire 14c 1 ~14c 6 is the diameter D 2 of the minimum diameter of the tire 14c 6 located closest to the roadway centerline side during running of the snow groomer device 10 is located on the most sidewalk side during running of the snow groomer 10 The tire 14c 1 is selected so as to be 0.4 to 0.6 times the diameter D 1 of the tire 14c 1 (that is, 0.4D 1 ≦ D 2 ≦ 0.6D 1 ), and the tire 14c It is selected so as to gradually become smaller in diameter toward the 1 to the tire 14c 6.

タイヤの径をこのように歩道側から車道センターライン側に向かって徐々に小さくなるように選定することにより、圧雪作業時に歩道側の雪を徐々に車道センターライン側に移動させ、効率的な圧雪作業を行うことが可能になる。また、タイヤ径を異径とすることにより、道路の横断面がセンターライン個所が高く、歩道側個所が低くなるような、上方に凸のいわゆる“カマボコ”形状に形作られているため（図３（ｂ）参照）、路面の横断面形状に沿って均一に圧雪することも可能になる（タイヤを異径にしないと、センターライン側の雪は密に圧雪され、歩道側の雪は緩く圧雪されることとなり、圧雪面が不均一になるという不都合が生ずる）。なお、テーパ状圧雪機１４に油圧シリンダ（図示せず）を連結させ、圧雪作業時に油圧シリンダによりテーパ状圧雪機１４を雪面に押しつけることにより、より効率的な圧雪作業が可能になる。   By selecting the tire diameter so that it gradually decreases from the sidewalk side toward the roadway center line side, the snow on the sidewalk side is gradually moved toward the roadway centerline side during snow pressure work, so that efficient snow pressure can be achieved. It becomes possible to work. Also, by making the tire diameter different, the road cross-section is shaped into a so-called “kamaboko” shape that protrudes upward so that the centerline part is high and the sidewalk side part is low (FIG. 3). (Refer to (b)), it is also possible to uniformly compress snow along the cross-sectional shape of the road surface (if the tires are not made different diameters, the snow on the centerline side will be densely compressed and the snow on the sidewalk side will be loosely compressed) As a result, there is a disadvantage that the snow-snow surface becomes uneven). It should be noted that a hydraulic cylinder (not shown) is connected to the tapered snow pressure machine 14 and the tapered pressure snow machine 14 is pressed against the snow surface by the hydraulic cylinder at the time of snow pressure work, thereby enabling more efficient snow pressure work.

圧雪機１４がテーパ状になっているため、圧雪装置１０を安定的に直進走行させることができるか懸念される。この点を検証するため、本発明者は、圧雪装置１０を走行させる実験を行ったところ、支障なく直進走行させることができることを確認した。これは、上述のように道路の横断面が“カマボコ”形状に形作られているため、テーパ状の圧雪機１４であっても円滑な直進走行が可能になるものと推測される。   Since the snow pressure machine 14 is tapered, there is concern about whether or not the snow pressure device 10 can travel straight ahead stably. In order to verify this point, the present inventor conducted an experiment in which the snow snow device 10 traveled, and confirmed that it could travel straight without any trouble. This is presumed that since the road cross section is formed in a “kamaboko” shape as described above, smooth straight traveling is possible even with the tapered snow blower 14.

なお、テーパ状圧雪機１４は、ホイールローダ１２の車体後部に装備されている排土板に連結アーム１４ａを介して装着するのがよい。   The tapered snow blower 14 is preferably attached to a soil discharge plate provided at the rear of the vehicle body of the wheel loader 12 via a connecting arm 14a.

圧雪装置１０の使用に際して、ホイールローダ１２のバケットを適宜用いて除雪しつつ、圧雪機１４により圧雪作業を行ってもよい。とりわけ、バス停留所や仲小路の十字路においてバケットで雪を取り出して雪面に均一に散布しつつ圧雪機１４により圧雪すると、効率的な圧雪作業が可能になる。   When the snow pressure device 10 is used, the snow pressure work may be performed by the snow pressure machine 14 while removing snow using the bucket of the wheel loader 12 as appropriate. In particular, when snow is taken out by buckets at a bus stop or Nakakoji crossing and sprayed uniformly on the snow surface while the snow is being pressed by the snow pressure machine 14, efficient snow pressure work is possible.

圧雪装置１０について実施した実験の結果について以下に示す（なお、実験には、降雪が２０ｃｍ〜３５ｃｍの時を選び、日立建機製のバックホーを用いて行った）。１６輪トレーラーの後部６輪軸（軸長３０００）を取り出し、中心部より右側３輪はそのままにし、中心部より左側に１３ｃｍずつ高さの異なるタイヤホイールを組み込み、タイヤにチェーンを装着したものを圧雪機１４とした。右折・左折を繰り返しながら１００ｍ程度走行させたところ、反対側車線に雪がはみ出ることもなく、方向転換も支障なく行うことができ、圧雪面にチェーンによる凹凸も明瞭に形作られ、良好な結果が得られた。   The results of an experiment conducted on the snow pressure device 10 are shown below (note that the experiment was performed using a backhoe manufactured by Hitachi Construction Machinery, when the snowfall was 20 cm to 35 cm). Take out the rear 6-wheel axle (axial length 3000) of the 16-wheel trailer, leave the three wheels on the right side from the center, and install tire wheels with different heights of 13cm on the left side from the center. It was set as machine 14. When driving about 100m while repeating right and left turns, snow does not protrude into the opposite lane, the direction can be changed without any problem, and the unevenness caused by the chain is clearly formed on the snow surface and good results are obtained. It was.

図４は、圧雪装置１０の変形形態を示した側面図、図５は、図４の圧雪装置の平面図である。図４及び図５に示される圧雪装置２０は、圧雪機２４がホイールローダ１２ではなく、タイヤショベル２２に取り付けられている点を除いて、図１及び図２に示される圧雪装置１０と実質的に同一の構成を有している。なお、図４及び図５において参照符合２４ａ、２４ｂ、２４ｃ1 〜２４ｃ6 は、連結アーム、回転シャフト、チェーン付きタイヤをそれぞれ示している。 FIG. 4 is a side view showing a modified embodiment of the snow pressure device 10, and FIG. 5 is a plan view of the snow pressure device of FIG. The snow pressure device 20 shown in FIGS. 4 and 5 is substantially the same as the snow pressure device 10 shown in FIGS. 1 and 2 except that the snow pressure machine 24 is attached to the tire shovel 22 instead of the wheel loader 12. Have the same configuration. Incidentally, reference numerals 24a, 24b, 24c 1 ~24c 6 in FIGS. 4 and 5 show the coupling arm, the rotating shaft, a chain with a tire, respectively.

図１〜図５において圧雪機１４、２４が異径のタイヤで形成されているが、タイヤの代わりに、周面に突起を設けたテーパ状又は円筒状のローラ（図示せず）を用いてもよい。   1 to 5, the snow blowers 14 and 24 are formed of tires of different diameters, but instead of tires, tapered or cylindrical rollers (not shown) having protrusions on the peripheral surface are used. Also good.

圧雪を継続的に行うと、路面の圧雪層が堆積し、相当の厚さになることが懸念される。この点を検証するために、本発明者は、１シーズン継続して圧雪作業を行った場合に圧雪層の堆積厚さがどの程度になるのかを計測したところ、車両の通行量の少ない６ｍ、８ｍ幅の中小道路で最大堆積厚さが１５ｃｍ程度、大型車両（バス、トラック等）の通行量の多い幹線道路では堆積厚さが５ｃｍ〜８ｃｍ程度におさまることを確認した。１シーズン通しての堆積厚さがこの程度におさまるのは、圧雪装置による雪の圧縮、車両の排気熱や日射による雪の融解が原因であると推測される。圧雪層の堆積厚さがこの程度におさまること、転圧機により圧雪面に凹凸が付けられることを考慮すると、車両の通行には支障がないものと予測される。   There is a concern that if the snow is continuously applied, the snow layer on the road surface accumulates and the thickness becomes considerable. In order to verify this point, the present inventor measured the accumulated thickness of the compressed snow layer when the compressed snow work was continued for one season. It was confirmed that the maximum deposition thickness was about 15 cm on a small and medium-sized road of 8 m width, and that the deposition thickness was about 5 cm to 8 cm on a highway with large traffic (buses, trucks, etc.). The reason why the accumulated thickness throughout the season falls to this level is presumed to be due to the compression of snow by the snow pressure device, the melting of snow by the exhaust heat of the vehicle and solar radiation. Considering that the thickness of the snow-capped layer is reduced to this level and that the surface of the snow-capped surface is uneven by a rolling mill, it is predicted that there will be no hindrance to vehicle traffic.

本発明は、以上の発明の実施の形態に限定されることなく、特許請求の範囲に記載された発明の範囲内で、種々の変更が可能であり、それらも本発明の範囲内に包含されるものであることはいうまでもない。   The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, it is something.
