Description

本発明は、車両が通行する道路上に存在する落下物を、自走する車両を利用して回収するための、路上落下物回収装置に関するものである。   The present invention relates to an on-road falling object collection device for collecting falling objects existing on a road on which a vehicle passes by using a self-propelled vehicle.

車両が通行する道路、特に高速道路において、走行する貨物トラックなどの車両から落下し路上に残った資材やゴミなどの落下物は、後続の車両の走行の妨げとなり、事故につながるおそれがある。そこで、これら落下物をできるだけ早急に回収することが望まれるが、交通量の多い道路で、落下物が発生する度に道路を通行止めとして落下物を回収することは、事実上不可能である。このため、従来は車両が断続的に走行している中で、人が道路を横断し、手作業により落下物を回収する方法が採られてきた。ただし、これには安全性において大きな問題がある。そこで、これまでに、道路を通行止めとすることなく、路上の落下物を安全に回収するために、自走する車両を利用して落下物を回収する試みがなされている。   On roads where vehicles pass, especially highways, falling objects such as materials and garbage that have fallen from vehicles such as freight trucks that have traveled on the roads may interfere with the driving of subsequent vehicles and may lead to accidents. Therefore, it is desired to collect these fallen objects as soon as possible. However, it is virtually impossible to collect the fallen objects by blocking the roads every time the fallen objects are generated on a road with a lot of traffic. For this reason, conventionally, a method has been adopted in which a person crosses a road and a fallen object is manually collected while the vehicle is traveling intermittently. However, this has a major safety problem. So far, attempts have been made to collect fallen objects using a self-propelled vehicle in order to safely collect fallen objects on the road without blocking the road.

例えば、特開2007−2633号公報には、小型の回収機構を備え、走行しながらの障害物回収を行なうことができる路面障害物回収装置が開示されている。この路面障害物回収装置は、走行車両の前面に装着することで所定の作業車両が構成され、その車両で道路パトロールを実施して路面に落下物が存在していることを発見した場合には、回収機構部を回収機構部に設けられた車輪が接地する状態となるまで下降させ、スクレーパーを前方に倒し、障害物位置を通過させることで、スクレーパーで障害物を掬い上げ、収納部に収納して、路面上から障害物を回収することができる。   For example, Japanese Unexamined Patent Application Publication No. 2007-2633 discloses a road surface obstacle recovery device that includes a small recovery mechanism and can perform obstacle recovery while traveling. When this road surface obstacle collecting device is mounted on the front surface of a traveling vehicle, a predetermined work vehicle is configured, and when road patrol is performed with the vehicle, it is found that there is a fallen object on the road surface. The collection mechanism is lowered until the wheels provided in the collection mechanism come into contact with the ground, the scraper is moved forward, and the obstacle position is passed, and the obstacle is picked up by the scraper and stored in the storage section. Thus, the obstacle can be collected from the road surface.

特開2007−2633号公報JP 2007-2633 A

しかしながら、上記路面障害物回収装置を含めた従来の回収方法では、様々な形状の落下物を、高い走行速度、例えば時速60kmを維持しながら回収することはできなかった。例えば、本発明者による試験によると、スペアタイヤなど比較的体積の大きい落下物では、回収装置との衝突によって弾き飛ばされて、回収装置内に回収することができないという事象が確認された。また、毛布やブルーシートなどシート状の落下物では、スクレーパー下部をすり抜けて、回収装置内に回収することができないという事象が確認された。そのため、これらの落下物を回収するためには一時停止させなければならない場合があり、回収作業効率を著しく低下させるという問題があった。   However, with the conventional collection method including the road surface obstacle collection device, it has been impossible to collect falling objects of various shapes while maintaining a high traveling speed, for example, 60 km / h. For example, according to a test by the present inventor, it was confirmed that a fallen object having a relatively large volume, such as a spare tire, was blown off by a collision with the collection device and could not be collected in the collection device. In addition, it was confirmed that a sheet-like fallen object such as a blanket or a blue sheet could not be recovered in the recovery device by passing through the lower part of the scraper. Therefore, in order to collect these fallen objects, there is a case where it must be temporarily stopped, and there is a problem that the collection work efficiency is remarkably lowered.

そこで、本発明は、様々な形状の路上落下物を、一時停止することなく、好ましくは高い走行速度、例えば時速60kmを維持しながら回収できる路上落下物回収装置を提供することを目的とする。   Accordingly, an object of the present invention is to provide an on-road falling object recovery apparatus that can recover various shapes of road falling objects while maintaining a high traveling speed, for example, 60 km / h, without temporarily stopping.

本発明に係る路上落下物回収装置は、路上の回収対象物を収容する回収物収容部が、その奥行き方向が走行方向と平行し、前記回収対象物の受入口が進路に向かって開口する配置とされる。そして、前記受入口の下部に前記受入口の幅全体に亘って前記回収対象物と接触する接触部を備え、前記接触部は、延伸方向が前記走行方向に対し傾斜しているエッジと、前記エッジよりも広幅で前記エッジに平行して延伸し路面側に配置される縁辺が路面に接する補助エッジを有する。前記補助エッジは弾性樹脂材で形成され前記路面に密着する柔軟性を有している。
In the on-road falling object recovery apparatus according to the present invention, the recovered object storage unit for storing the recovery object on the road has an arrangement in which a depth direction thereof is parallel to a traveling direction, and a receiving port of the recovery object opens toward a course. It is said. And it is provided with a contact part which contacts the above-mentioned recovery subject over the whole width of the above-mentioned entrance at the lower part of the above-mentioned entrance, and the above-mentioned contact part has an edge whose extension direction is inclined with respect to the above-mentioned running direction, An edge that is wider than the edge and extends parallel to the edge and is disposed on the road surface side has an auxiliary edge that contacts the road surface. The auxiliary edge is formed of an elastic resin material and has a flexibility to be in close contact with the road surface .

前記エッジと前記補助エッジは、前記受入口の幅の中央位置で前記進路と逆方向に向って凹み、前記中央位置から前記受入口の両幅の各々に、前記走行方向に対し傾斜して延伸していてもよい。   The edge and the auxiliary edge are recessed toward the direction opposite to the path at the center position of the width of the receiving port, and extend from the center position to both widths of the receiving port at an angle with respect to the traveling direction. You may do it.

前記受入口の進路側に、複数の短冊を前記走行方向と直交する方向に並べて構成した跳ね返り防止部を備えていてもよい。   A rebound prevention unit configured by arranging a plurality of strips in a direction orthogonal to the traveling direction may be provided on the path side of the receiving port.

前記跳ね返り防止部は、前記回収物収容部の壁材に、前記走行方向に沿った位置調節が可能な状態で固定された側方包囲板を介して連結されていてもよい。   The rebound prevention part may be connected to the wall material of the collected matter storage part via a side surrounding plate fixed in a state in which the position adjustment along the traveling direction is possible.

前記弾性樹脂材は、路面に密接する柔軟性と、重量の大きい落下物に衝突した時にも変形又は破損しない強度を有するものであれば制限はないが、ポリカーボネート(厚さ2mm、及び3mm)、塩化ビニール(厚さ2mm、3mm、及び4mm)、ポリウレタン(厚さ3mm)について評価試験を行なった場合、ポリカーボネート(厚さ3mm)が柔軟性及び強度において総合的に優れていることが確認された。   The elastic resin material is not limited as long as it has flexibility to be in close contact with the road surface and strength not to be deformed or damaged even when it collides with a heavy falling object, polycarbonate (thickness 2 mm and 3 mm), When an evaluation test was performed on vinyl chloride (thickness 2 mm, 3 mm, and 4 mm) and polyurethane (thickness 3 mm), it was confirmed that polycarbonate (thickness 3 mm) was comprehensively excellent in flexibility and strength. .

本発明に係る路上落下物回収装置では、エッジが走行方向に対し傾斜して延伸しているため、回収対象物がエッジに衝突した際に回収対象物に作用する反力を走行方向及び走行方向に直行する方向に分散させることができる。そのため、高速で走行しても、回収対象物を走行方向に大きく弾き飛ばすことなく回収物収容部内に回収することが可能となる。また、エッジとは別に、路面に接する補助エッジを設けたことにより、毛布やブルーシート等の薄い形状のものがエッジの下をすり抜けることを防止することができ、回収物収容部内に回収することができる。従って、様々な形状の路上落下物を、一時停止することなく走行状態を維持しながら回収することが可能となる。   In the on-road falling object collecting apparatus according to the present invention, the edge is inclined and extended with respect to the traveling direction, and therefore, the reaction force acting on the collected object when the collected object collides with the edge is determined as the traveling direction and the traveling direction. Can be distributed in a direction perpendicular to For this reason, even if the vehicle travels at a high speed, it is possible to collect the collected object in the collected material container without greatly flying away the collected object in the traveling direction. Moreover, by providing an auxiliary edge that is in contact with the road surface separately from the edge, it is possible to prevent a thin shape such as a blanket or a blue sheet from slipping under the edge, and collect it in the collected matter storage unit. Can do. Therefore, it is possible to collect falling objects on the road having various shapes while maintaining the running state without temporarily stopping.

エッジと補助エッジは、受入口の幅の中央位置で前記進路と逆方向に向って凹み、中央位置から受入口の両幅の各々に、走行方向に対し傾斜して延伸するもの、すなわち平面視V形とすれば、路上落下物を中央からずれた位置で受けたときでも、中央部に向けて弾き飛ばすことができるので、走行車線外の方向への飛び出しを防ぎ、回収作業をより確実に行なうことができる。   The edge and the auxiliary edge are recessed at the center position of the width of the receiving port in the direction opposite to the course, and extend from the central position to both widths of the receiving port at an inclination with respect to the traveling direction, that is, in plan view With the V shape, even when a fallen object on the road is received at a position deviated from the center, it can be flipped off toward the center, preventing jumping out of the driving lane and collecting work more reliably. Can be done.

更に、回収物収容部受入口の進路側に、複数の短冊を前記走行方向と直交する方向に並べて構成した跳ね返り防止部を設けることにより、収容した回収物が再び路上に飛び出して放置されることを防止し、高速走行における回収作業をより確実に行なうことが可能となる。特に、時速60km程度の高い走行速度を維持しながら回収する場合に有効に作用する。なお、回収物収容部の内部にも、同様に、複数の短冊を走行方向と直交する方向に並べて、回収物の跳ね返り防止効果を更に高めることとしてもよい。   In addition, by providing a bounce prevention part configured by arranging a plurality of strips in a direction perpendicular to the traveling direction on the path side of the collection object receiving part reception port, the collected collection object can jump out and be left on the road again. This makes it possible to more reliably carry out the recovery operation at high speeds. In particular, it works effectively when collecting while maintaining a high traveling speed of about 60 km / h. Similarly, a plurality of strips may be arranged in the direction perpendicular to the traveling direction inside the collected material storage unit to further enhance the effect of preventing the collected material from rebounding.

更にまた、跳ね返り防止部を、回収物収容部の壁材に、走行方向に沿った位置調節が可能な状態で固定された側方包囲板を介して連結することで、エッジと跳ね返り防止部との間隔を回収物の形状に合わせて調整し、収容した回収物の路上への再飛び出しをより確実に防止することができる。   Furthermore, the rebound prevention part is connected to the wall material of the collection object storage part via a side surrounding plate fixed in a state in which the position adjustment along the traveling direction is possible, and the edge and the rebound prevention part. This interval can be adjusted in accordance with the shape of the collected material, and the collected collected material can be more reliably prevented from jumping out onto the road.

With reference to FIGS. 1-4, the Example of the falling object collection | recovery apparatus on the road which concerns on this invention is described.
As shown in FIG. 4, the on-road falling object collecting apparatus 1 is used by being attached to an on-road work vehicle 2 that includes an attaching / detaching portion such as a snow removal head (snow plow). On the back of the fallen object collection device 1 on the road, there is an attachment structure 3 for attachment to the road work vehicle 2. Since this attachment structure 3 is a publicly known one, its description and FIGS. The illustration in FIG.

この路上落下物回収装置1では、路上の回収対象物を収容する回収物収容部11として直方体の金属製箱体が採用されている。金属製箱体の長手方向に対峙する側面の一方を、回収対象物の受入口12として開口し、回収物収容部の背面をなす受入口12の対面13の裏側には、路上作業車2への取付構造3が設けられている。そして、図4に示すように、回収物収容部11の奥行き方向となる、金属製箱体の長手方向が、走行方向と平行するように、路上作業車2に取り付けられ、受入口12が進路に向って開口する配置とされる。   In this on-road falling object recovery apparatus 1, a rectangular parallelepiped metal box is adopted as the recovered object storage unit 11 for storing the recovery object on the road. One of the side surfaces facing the longitudinal direction of the metal box is opened as the collection object receiving port 12, and the back side of the facing surface 13 of the receiving port 12 that forms the back surface of the collected object storage unit is connected to the road work vehicle 2. The mounting structure 3 is provided. And as shown in FIG. 4, it attaches to the road work vehicle 2 so that the longitudinal direction of the metal box used as the depth direction of the collection | recovery accommodating part 11 may be parallel to a running direction, and the receiving port 12 is a course. It is the arrangement | positioning which opens toward.

回収物収容部11の内面には、回収物の衝撃を吸収するためのゴム製緩衝材が貼られるとともに、天井面における受入口12の上部縁辺近傍は網14で形成され、受入口12の近傍での回収物の跳ね飛びによる衝撃を緩和するものとなっている。また、対面13には図示しない通気口が貫設されており、走行時にける回収物収容部11の空気抵抗が低減されるものとなっている。更に、対面13の外側下部には、路上落下物回収装置1全体が支える車輪4が取り付けられ、取付構造3に対する負担が軽減されている。なお、図1、及び図3においては、説明の便宜上、車輪4の図示は省略されている。   A rubber cushioning material for absorbing the impact of the collected material is affixed to the inner surface of the collected material container 11, and the vicinity of the upper edge of the receiving port 12 on the ceiling surface is formed by a mesh 14, and the vicinity of the receiving port 12. It is intended to alleviate the impact caused by the jumping of collected items. In addition, a ventilation hole (not shown) is provided in the facing surface 13 so that the air resistance of the collected matter storage portion 11 during traveling is reduced. Furthermore, the wheel 4 which the road fall object collection apparatus 1 whole supports is attached to the outer side lower part of the facing 13, and the burden with respect to the attachment structure 3 is eased. In FIGS. 1 and 3, the wheels 4 are not shown for convenience of explanation.

回収物収容部11の受入口12の下部には、受入口12の幅全体に亘って回収対象物と接触する接触部15が設けられている。接触部15は、延伸方向が走行方向に対し傾斜しているエッジ16と、このエッジ16よりも広幅でエッジ16に平行して延伸し路面側に配置される縁辺が路面に接する補助エッジ17で構成されている。   A contact portion 15 that is in contact with the collection target is provided across the entire width of the receiving port 12 at the lower portion of the receiving port 12 of the collected material storage unit 11. The contact portion 15 includes an edge 16 whose extending direction is inclined with respect to the traveling direction, and an auxiliary edge 17 whose width is wider than the edge 16 and extends in parallel to the edge 16 and arranged on the road surface side and in contact with the road surface. It is configured.

エッジ16と補助エッジ17は、受入口12の幅の中央位置18で進路と逆方向に向って凹み、中央位置18から受入口の両幅の各々に、走行方向に対し傾斜して延伸している。すなわち、平面視V形となっている。図2(b)に示す、エッジ16及び補助エッジ17の延伸方向が走行方向に対し傾斜する角度R2、R3は、回収対象物への反力を分散させる方向を考慮して決めればよいが、45度の場合、走行方向及び走行方向と直交する方向へ反力を均等に分散させることができる。なお、図2(b)では、説明の明確化のため接触部15のみを示すものとする。また、白抜き矢線は走行方向を示す。   The edge 16 and the auxiliary edge 17 are recessed in the direction opposite to the course at the central position 18 of the width of the receiving port 12 and extend from the central position 18 to both widths of the receiving port in an inclined manner with respect to the traveling direction. Yes. That is, it has a V shape in plan view. The angles R2 and R3 at which the extending direction of the edge 16 and the auxiliary edge 17 shown in FIG. 2B is inclined with respect to the traveling direction may be determined in consideration of the direction in which the reaction force to the collection target is dispersed. In the case of 45 degrees, the reaction force can be evenly distributed in the traveling direction and the direction orthogonal to the traveling direction. In FIG. 2B, only the contact portion 15 is shown for clarity of explanation. A white arrow indicates a traveling direction.

図2(a)に示す、エッジ16の路面に対する角度R1は30度とされている。この角度は、使用状況に応じて適宜調整することができるが、回収対象物からの衝撃を抑えるためにはできるだけ小さくすることが好ましい。なお、少なくとも30度であれば、時速60kmで大型トラックのタイヤを回収できることが確認されている。   The angle R1 of the edge 16 with respect to the road surface shown in FIG. 2A is 30 degrees. This angle can be appropriately adjusted according to the use situation, but it is preferable to make it as small as possible in order to suppress the impact from the collection object. It has been confirmed that tires of large trucks can be collected at a speed of 60 km / h at least 30 degrees.

エッジ16の素材にはウレタンゴム、補助エッジ17の素材にはポリカーボネートが使用されている。エッジ16は、通常除雪車用スノープラウの先端に装着するウレタンゴムを使用している。ウレタンゴムは、弾性体であるので路面に接触しても路面を傷つけず、しかも耐摩耗性に優れるという特徴があり、除雪車用スノープラウでの使用実績が豊富である。また、補助エッジ17の素材は、路面に密接する柔軟性と、重量の大きい落下物に衝突した時にも変形又は破損しない強度を有することが必要であることから、ポリカーボネートが好ましい。ただし、エッジ16、補助エッジ17の材質の制限はなく、使用状況に適したその他の材料を適宜採用できる。   The edge 16 is made of urethane rubber, and the auxiliary edge 17 is made of polycarbonate. The edge 16 is made of urethane rubber that is usually attached to the tip of a snow plow for a snowplow. Since urethane rubber is an elastic body, it does not damage the road surface even when it comes into contact with the road surface, and has excellent wear resistance, and has abundant experience in use in snow plows for snowplows. Further, the material of the auxiliary edge 17 is preferably polycarbonate because it is required to have flexibility to be in close contact with the road surface and strength to prevent deformation or breakage even when it collides with a heavy falling object. However, the material of the edge 16 and the auxiliary edge 17 is not limited, and other materials suitable for the use situation can be appropriately adopted.

高速走行における回収作業をより確実に行なうにあたり、収容した回収物が再び路上に飛び出すことを防止する必要がある場合には、図3に示すように、受入口12の進路側に跳ね返り防止部21を設けることが好ましい。図3に示す跳ね返り防止部21は、複数の短冊を走行方向と直交する方向に並べて構成したものである。この跳ね返り防止部21を構成する短冊は金属薄板で形成されているが、回収物の跳ね返る力を十分に吸収できるものであれば、その他の材質としてもよい。   When it is necessary to prevent the collected collected material from jumping out again on the road in order to more reliably perform the collection work in the high-speed traveling, as shown in FIG. Is preferably provided. The bounce prevention unit 21 shown in FIG. 3 is configured by arranging a plurality of strips in a direction orthogonal to the traveling direction. The strips constituting the rebound preventing portion 21 are formed of a thin metal plate, but other materials may be used as long as they can sufficiently absorb the rebounding force of the recovered material.

跳ね返り防止部21は、回収物収容部11の壁材に、走行方向に沿った位置調整が可能な状態で固定された側方包囲板22を介して連結されている。側方包囲板22は、回収物収容部11の壁材に設けられたボルト孔にボルト締めで固定されているが、このボルト孔は走行方向に沿って複数設けられており、固定するボルト孔を変更することで、走行方向に沿った位置調整が可能となっている。ただし、このように位置調整が可能な状態で固定する方法に制限はなく、例えば、走行方向に伸びるスリットに、固定軸を挿入する方法を採用してもよい。なお、このような固定構造は公知であるため図示を省略する。   The bounce prevention unit 21 is connected to the wall material of the collected matter storage unit 11 via a side surrounding plate 22 fixed in a state where position adjustment along the traveling direction is possible. The side surrounding plate 22 is fixed by bolting to a bolt hole provided in the wall material of the collected material storage unit 11, and a plurality of the bolt holes are provided along the traveling direction. It is possible to adjust the position along the traveling direction. However, there is no limit to the method of fixing in a state where position adjustment is possible in this way. For example, a method of inserting a fixed shaft into a slit extending in the traveling direction may be employed. In addition, since such a fixing structure is well-known, illustration is abbreviate | omitted.

跳ね返り防止部21と受入口12の隙間の天井部は網23で形成され、前記網14と同様に、受入口12の近傍での回収物の跳ね飛びによる衝撃を緩和するものとなっている。   The ceiling portion of the gap between the bounce prevention portion 21 and the receiving port 12 is formed by a net 23, and, like the net 14, the impact caused by the splashing of the collected material in the vicinity of the receiving port 12 is reduced.

試験用走行路上に、実際の落下物を想定した以下の供試体を置き、上記跳ね返り部21を取り付けない状態の路上落下物回収装置を装着した車両を走行速度時速30kmで走行させた場合(実施例1)と、跳ね返り部21を取り付けた状態の路上落下物回収装置を装着した車両を走行速度時速60kmで走行させた場合(実施例2)での回収試験を行なった。また、比較例として、接触部15が走行方向に対し傾斜せず補助エッジ17を備えないもの(図5)を使用して、車両の走行速度は時速30kmとして回収試験を行なった。試験結果を表1に示す。なお、回収物収容部11として、幅245cm、奥行き141cm、高さ100cmの金属製箱体を採用し、実施例2の跳ね返り部21の受入口12からの距離は70cmとした。   When the following specimen assuming an actual fallen object is placed on the test runway, and the vehicle equipped with the on-road fallen object collection device without the rebound portion 21 is run at a running speed of 30 km / h (implementation) Example 1) and a recovery test in a case where the vehicle equipped with the falling object recovery device with the bounce portion 21 attached was run at a traveling speed of 60 km / h (Example 2). Further, as a comparative example, a recovery test was performed using a vehicle in which the contact portion 15 is not inclined with respect to the traveling direction and does not include the auxiliary edge 17 (FIG. 5), and the vehicle traveling speed is 30 km / h. The test results are shown in Table 1. Note that a metal box having a width of 245 cm, a depth of 141 cm, and a height of 100 cm was adopted as the collected material storage unit 11, and the distance from the receiving port 12 of the rebound portion 21 of Example 2 was set to 70 cm.

表1に示すように、エッジ16が走行方向に傾斜せず補助エッジ17を備えていない比較例では、高さの低い供試体2、供試体3を回収できないのに対し、実施例1、実施例2では、これら供試体を回収することができた。また、実施例1の走行速度は、時速30kmという低速であるが、実施例2に示すように、跳ね返り防止部21を取り付けることで、時速60kmという高速での落下物回収が可能となることが確認できた。すなわち、実施例1で回収成功した供試体1、供試体2および供試体4は、実施例2では走行速度が高速になったことにより、落下物を押し出したものの、跳ね返り防止部21が存在することによって、回収に成功している。また、実施例1では強く弾き飛ばしてしまって回収できなかった供試体6を、実施例2では跳ね返り防止部21が存在することによって回収に成功した。   As shown in Table 1, in the comparative example in which the edge 16 is not inclined in the running direction and the auxiliary edge 17 is not provided, the specimen 2 and specimen 3 having a low height cannot be collected, whereas the embodiment 1 In Example 2, these specimens could be collected. Moreover, although the traveling speed of Example 1 is a low speed of 30 km / h, as shown in Example 2, it is possible to collect the fallen object at a high speed of 60 km / h by attaching the bounce prevention unit 21. It could be confirmed. That is, the specimen 1, specimen 2 and specimen 4 that were successfully collected in the example 1 pushed the fallen object due to the increased traveling speed in the example 2, but the bounce prevention part 21 exists. It has succeeded in collecting. In addition, the specimen 6 that could not be recovered because it was strongly bounced off in Example 1 was successfully recovered due to the presence of the rebound prevention part 21 in Example 2.
