Description

本発明は、シャシ上の塵埃を回収可能な塵埃回収位置と塵埃を排出可能な塵埃排出位置の間でホッパを移動し、塵埃排出位置でホッパから塵埃を排出可能なブラシ式路面清掃車のホッパ移動装置に関する。   The present invention relates to a hopper for a brush type road cleaning vehicle that moves a hopper between a dust collecting position where dust can be collected on a chassis and a dust discharging position where dust can be discharged, and can discharge dust from the hopper at the dust discharging position. It relates to a mobile device.

ブラシ式路面清掃車のホッパ移動装置に関して、特許文献１に記載された構造のものが知られている。これは、シャシ上にコンベア装置よりも前方の塵埃回収位置に配置されたホッパが、第１、第２シリンダの伸長動作により、リフトアームを旋回させ、コンベア装置及び主ブラシの上方を通過して車体の後方へ移動する。その際、シャシに立設された支柱の支点軸と同軸に固着された第１スプロケットと、ホッパに突設した支持軸と同軸に連結された第１スプロケットよりも大径の第２スプロケットがあり、両スプロケット間に張設したチェーンにより、車体後方へ移動するホッパの姿勢を維持する。また、第１スプロケットの径を、第２スプロケットの径より小さくしたことにより、ホッパの塵埃排出位置では、ホッパが塵埃排出側へ傾き、塵埃の排出をより迅速且つ容易に行える。そして、第２スプロケットと一体に設けられたガイドバーとホッパとの間に設けた第３シリンダの伸長動作により、ガイドバーに対してホッパを傾動させることで塵埃を排出する構造となっている。   The thing of the structure described in patent document 1 is known regarding the hopper moving device of a brush-type road surface cleaning vehicle. This is because the hopper arranged at the dust collection position in front of the conveyor device on the chassis turns the lift arm by the extension operation of the first and second cylinders and passes above the conveyor device and the main brush. Move to the rear of the car. At that time, there is a first sprocket that is fixed coaxially with the fulcrum shaft of the column that is erected on the chassis, and a second sprocket that is larger in diameter than the first sprocket that is connected coaxially with the support shaft protruding from the hopper. The posture of the hopper moving to the rear of the vehicle body is maintained by a chain stretched between the two sprockets. Further, by making the diameter of the first sprocket smaller than the diameter of the second sprocket, the hopper tilts toward the dust discharge side at the dust discharge position of the hopper, and dust can be discharged more quickly and easily. And it is the structure which discharges | emits dust by tilting a hopper with respect to a guide bar by the expansion | extension operation | movement of the 3rd cylinder provided between the guide bar and the hopper provided integrally with the 2nd sprocket.

本願発明の実施の形態について、図１〜図９により説明する。ブラシ式路面清掃車１は、シャシ２の左右両サイドで前後輪３，４の間に、一対の側ブラシ５，５を、回転可能且つ上下動可能に設ける一方、シャシ２の後方に主ブラシ６を配置して、側ブラシ５，５によってシャシ２の下部中央に掃き寄せた路面Ｆ上の塵埃を、主ブラシ６によって前側上方に掃き上げるようにしている。７は、シャシ２の上方左右及び主ブラシ６の上方を覆うカバーである。主ブラシ６は、その前方に縦姿勢で設けられたコンベア装置８の下端後方に回転可能に組み付けられるもので、掃き上げた塵埃はコンベア装置８によって上方へ搬送される。このコンベア装置８は、図１にも示すように、シャシ２の後方上部へ一体に組み付けられた支持フレーム９内で、シリンダ１０を用いた昇降機構１１によって上下動可能に支持されたもので、この昇降機構１１により、主ブラシ６及びコンベア装置８は、夫々下端が路面Ｆに接地する清掃位置（図１の二点鎖線位置）と、下端が路面Ｆから離れる待機位置（図１の実線位置）との間を昇降可能となっている。   Embodiments of the present invention will be described with reference to FIGS. The brush type road surface cleaning vehicle 1 is provided with a pair of side brushes 5 and 5 that are rotatable and vertically movable between the front and rear wheels 3 and 4 on both the left and right sides of the chassis 2, while the main brush is disposed behind the chassis 2. 6 is arranged so that dust on the road surface F swept to the lower center of the chassis 2 by the side brushes 5 and 5 is swept up by the main brush 6 to the upper front side. A cover 7 covers the upper left and right sides of the chassis 2 and the upper side of the main brush 6. The main brush 6 is rotatably assembled behind the lower end of the conveyor device 8 provided in a vertical posture in front of the main brush 6, and the cleaned dust is conveyed upward by the conveyor device 8. As shown in FIG. 1, the conveyor device 8 is supported by an elevating mechanism 11 using a cylinder 10 in a support frame 9 integrally assembled to the rear upper part of the chassis 2 so as to be movable up and down. By this elevating mechanism 11, the main brush 6 and the conveyor device 8 each have a cleaning position where the lower end contacts the road surface F (two-dot chain line position in FIG. 1) and a standby position where the lower end separates from the road surface F (solid line position in FIG. 1). ) Can be moved up and down.

また、支持フレーム９は、図２にも示すように、四角形の枠体１２と、その枠体１２の後端左右に立設された一対の支柱１３，１３と、その支柱１３，１３の上端間を連結する左右方向の連結バー１４と、各支柱１３，１３の上端と枠体１２の前端とを連結する一対のリブ１５，１５とを有してなり、枠体１２の上部前方に、ホッパ１６が設けられている。ホッパ１６は、後輪４よりも前方に位置して、上方後部に開口させた塵埃の受入口１７を、清掃位置にあるコンベア装置８の上部に臨ませて、コンベア装置８の上部から前方へ排出される塵埃を受入口１７から回収可能としたものである。さらに、ホッパ１６は、本発明の特徴であるホッパ移動装置１８により、塵埃を回収する図１の塵埃回収位置Ａと、図９のようにコンベア装置８及び主ブラシ６の上方を通過して車体の後方に突出し、回収した塵埃を排出する塵埃排出位置Ｂとの間で旋回移動可能に支持されている。ホッパ移動装置１８は、塵埃排出位置Ｂでホッパ１６の姿勢を塵埃排出可能な姿勢に回転させるホッパ回動用シリンダ機構１９を備えている。   Further, as shown in FIG. 2, the support frame 9 includes a quadrangular frame 12, a pair of support columns 13 and 13 erected on the left and right of the rear end of the frame 12, and upper ends of the support columns 13 and 13. It has a pair of ribs 15 and 15 that connect the connecting bar 14 in the left and right direction that connects between the upper end of each support column 13 and 13 and the front end of the frame body 12. A hopper 16 is provided. The hopper 16 is located in front of the rear wheel 4, and the dust receiving port 17 opened in the upper rear part faces the upper part of the conveyor device 8 in the cleaning position, and forwards from the upper part of the conveyor device 8. The discharged dust can be collected from the receiving port 17. Further, the hopper 16 passes through the dust collection position A in FIG. 1 where dust is collected by the hopper moving device 18 which is a feature of the present invention, and above the conveyor device 8 and the main brush 6 as shown in FIG. Projecting rearwardly, and supported so as to be pivotable between a dust discharge position B for discharging the collected dust. The hopper moving device 18 includes a hopper rotating cylinder mechanism 19 that rotates the posture of the hopper 16 to a posture capable of discharging dust at the dust discharge position B.

ホッパ移動装置１８について説明する。支持フレーム９の左右に立設する支柱１３の上方には、図３に示すように上ブラケット２０を介して上回転軸２１が左右方向に支持され、前記上回転軸２１に、リフトアーム２２の基端が回転可能に軸着されて、リフトアーム２２の先端が、ホッパ１６の左右に突設した下回転軸２３に回転可能に連結されている。また、上回転軸２１には、リフトアーム２２の左右でリフトアーム２２よりも短い一対の板体を有し、その板体の先端同士をリフトアーム２２の下側で互いに連結してなる補助アーム２４が回転可能に軸着されて、補助アーム２４の中間部位と、リフトアーム２２の先端寄り部位との間に、第１アクチュエータとしての第１シリンダ２５が、同じく補助アーム２４の中間部位と、枠体１２の下方に連結した下ブラケット２６の下端との間に、第２アクチュエータとしての第２シリンダ２７が、夫々伸縮動作可能に架設されている。   The hopper moving device 18 will be described. As shown in FIG. 3, an upper rotating shaft 21 is supported in the left-right direction above the support column 13 erected on the left and right of the support frame 9, and the upper rotating shaft 21 has a lift arm 22 mounted on the upper rotating shaft 21. The base end is rotatably attached to the shaft, and the tip of the lift arm 22 is rotatably connected to a lower rotary shaft 23 projecting from the left and right of the hopper 16. Further, the upper rotary shaft 21 has a pair of plates that are shorter than the lift arms 22 on the left and right sides of the lift arms 22, and the auxiliary arms formed by connecting the tips of the plates to each other below the lift arms 22. 24 is rotatably mounted, and a first cylinder 25 serving as a first actuator is provided between the intermediate portion of the auxiliary arm 24 and the tip portion of the lift arm 22. Between the lower end of the lower bracket 26 connected to the lower side of the frame body 12, a second cylinder 27 as a second actuator is installed so as to be able to extend and contract.

各シリンダ２５，２７の収縮状態では、リフトアーム２２及び補助アーム２４は夫々前側下方への旋回位置にあって、補助アーム２４は、枠体１２の略中央で左右方向へ架設された支持バー２８に当接して下方への回転が規制されている。この状態では、ホッパ１６は図１に示す塵埃回収位置Ａに支持される。第１シリンダ２５が伸長すると、リフトアーム２２は後方へ旋回し、第２シリンダ２７が伸長すると、補助アーム２４が上方へ旋回し、リフトアーム２２はさらに後方へ旋回する。尚、各シリンダの駆動はエアや作動油等による周知の流体供給回路によって行われる。   In the contracted state of each cylinder 25, 27, the lift arm 22 and the auxiliary arm 24 are respectively in a pivoting position to the lower front side, and the auxiliary arm 24 is supported in the left-right direction substantially at the center of the frame body 12. Rotation in the downward direction is restricted in contact with. In this state, the hopper 16 is supported at the dust collection position A shown in FIG. When the first cylinder 25 extends, the lift arm 22 turns rearward. When the second cylinder 27 extends, the auxiliary arm 24 turns upward, and the lift arm 22 further turns backward. Each cylinder is driven by a known fluid supply circuit using air, hydraulic oil, or the like.

枠体１２の上ブラケット２０に固着された上回転軸２１に同軸に第１スプロケット２９が回転可能に設けられており、下回転軸２３側には、第１スプロケット２９よりも小径となる第２スプロケット３０が下回転軸２３と同軸に一体に固着されている。両スプロケット間には、チェーン３１が巻き掛けられている。   A first sprocket 29 is rotatably provided coaxially with an upper rotating shaft 21 fixed to the upper bracket 20 of the frame body 12, and a second diameter having a smaller diameter than the first sprocket 29 is provided on the lower rotating shaft 23 side. The sprocket 30 is fixed integrally with the lower rotating shaft 23 in a coaxial manner. A chain 31 is wound between the two sprockets.

第１スプロケット２９の内側には、ホッパ回動用シリンダ機構１９が設けられている。前記ホッパ回動用シリンダ機構１９は、第３シリンダ３２、第４シリンダ３３、上回動部材３４、下回動部材３５で構成されている。図４に示すように、第１スプロケット２９が回転可能に設けられている上回転軸２１に上回動部材３４の基端が回動可能に設けられると共に上回動部材３４の基端が第１スプロケット２９に一体に取り付けられ、上回動部材３４の先端は、第４シリンダ３３の先端と連結されている。前記第４シリンダ３３の基端は、支持フレーム９に基端が回動可能に設けられた下回動部材３５の先端と回動可能に連結されている。下回動部材３５の中間部位と支持フレーム９は第３シリンダ３２によって連結されており、第３シリンダ３２が伸長すると下回動部材３５と一体に第４シリンダ３３、上回動部材３４が回転するので、上回動部材３４が一体に連結された第１スプロケット２９が回転する。第４シリンダ３３が伸長すると上回動部材３４が回転するので第１スプロケット２９がさらに回転する。これにより塵埃排出位置Ｂに移動したホッパ１６を塵埃排出可能な姿勢に回転することができる。また、両シリンダ３２，３３を車体側に設けたので、従来のようにホッパを塵埃を排出可能な姿勢に回転するシリンダまで長い配管を行う必要がなく、両シリンダ３２，３３までの配管が短く簡略になる。さらに、ホッパ１６にシリンダを設けないことで、ホッパ１６自体が軽くなるので、少ない力でリフトアーム２２の旋回を行うことができる。   A hopper rotating cylinder mechanism 19 is provided inside the first sprocket 29. The hopper turning cylinder mechanism 19 includes a third cylinder 32, a fourth cylinder 33, an upper turning member 34, and a lower turning member 35. As shown in FIG. 4, the upper end of the upper rotating member 34 is rotatably provided on the upper rotary shaft 21 on which the first sprocket 29 is rotatably provided, and the base end of the upper rotating member 34 is first. The tip end of the upper rotating member 34 is connected to the tip end of the fourth cylinder 33. The base end of the fourth cylinder 33 is rotatably connected to the tip of a lower rotating member 35 whose base end is rotatably provided on the support frame 9. The intermediate portion of the lower rotating member 35 and the support frame 9 are connected by a third cylinder 32. When the third cylinder 32 extends, the fourth cylinder 33 and the upper rotating member 34 rotate together with the lower rotating member 35. Therefore, the first sprocket 29 to which the upper rotating member 34 is integrally connected rotates. When the fourth cylinder 33 extends, the upper rotating member 34 rotates, so that the first sprocket 29 further rotates. As a result, the hopper 16 that has moved to the dust discharge position B can be rotated to a posture in which dust can be discharged. Further, since both cylinders 32 and 33 are provided on the vehicle body side, it is not necessary to provide a long pipe to the cylinder that rotates the hopper in a posture capable of discharging dust as in the prior art, and the pipe to both cylinders 32 and 33 is short. Simplify. Furthermore, since the hopper 16 itself is lightened by not providing a cylinder in the hopper 16, the lift arm 22 can be turned with a small force.

上記のブラシ式路面清掃車１の動作について説明する。昇降機構１１によって主ブラシ６とコンベア装置８を清掃位置に移動させ、路面Ｆ上の塵埃をホッパ１６に回収する。回収終了後、図示しない排出スイッチを操作すると、ホッパ移動装置１８と前記ホッパ移動装置１８に備えられたホッパ回動用シリンダ機構１９によって塵埃の排出動作が行われる。図５に示すように、まず、第１シリンダ２５が先に伸長してリフトアーム２２を上方へ旋回させてホッパ１６を持ち上げ、第１シリンダ２５が最長となってリフトアーム２２が略起立姿勢となると、次に第２シリンダ２７が伸長して補助アーム２４を旋回させる。図６のように補助アーム２４及び第１シリンダ２５を介してリフトアーム２２がさらに後方へ旋回される。第２シリンダ２７が最長となると、ホッパ１６は塵埃排出位置Ｂに移動する。   Operation | movement of said brush type road surface cleaning vehicle 1 is demonstrated. The main brush 6 and the conveyor device 8 are moved to the cleaning position by the lifting mechanism 11 and the dust on the road surface F is collected in the hopper 16. When a discharge switch (not shown) is operated after the collection is completed, dust is discharged by the hopper moving device 18 and the hopper turning cylinder mechanism 19 provided in the hopper moving device 18. As shown in FIG. 5, first, the first cylinder 25 is first extended and the lift arm 22 is turned upward to lift the hopper 16, so that the first cylinder 25 is the longest and the lift arm 22 is in a substantially upright posture. Then, the second cylinder 27 extends to rotate the auxiliary arm 24. As shown in FIG. 6, the lift arm 22 is further pivoted backward via the auxiliary arm 24 and the first cylinder 25. When the second cylinder 27 is the longest, the hopper 16 moves to the dust discharge position B.

リフトアーム２２の旋回の間は、第３、第４シリンダ３２，３３は収縮状態を維持しているが、リフトアーム２２に対して回転可能となる第２スプロケット３０は、支持フレーム９に第３、第４シリンダ３２，３３によって固着されている第１スプロケット２９との間のチェーン３１によって左回転方向へ徐々に回転することになるため、ホッパ１６は、塵埃回収位置Ａから塵埃排出位置Ｂまで受入口１７が上側となる姿勢が略維持され、受入口１７から塵埃が溢れることはない。これは、第２スプロケット３０に対して第１スプロケット２９の径を大きく形成してあるので、リフトアーム２２が旋回することにより受入口１７が塵埃回収位置Ａでコンベア装置８に向いた状態よりシャシ２の前方側に回転して上を向くことになるためである。そして、図６に示すように塵埃排出位置Ｂでは、ホッパ１６は塵埃回収位置Ａでの姿勢よりも前方側へ傾き受入口１７が上を向いている。   While the lift arm 22 pivots, the third and fourth cylinders 32 and 33 maintain a contracted state, but the second sprocket 30 that can rotate with respect to the lift arm 22 is attached to the support frame 9 by the third. Since the chain 31 between the first sprocket 29 fixed by the fourth cylinders 32 and 33 is gradually rotated counterclockwise, the hopper 16 moves from the dust collection position A to the dust discharge position B. The posture in which the receiving port 17 is on the upper side is substantially maintained, and dust does not overflow from the receiving port 17. This is because the diameter of the first sprocket 29 is larger than that of the second sprocket 30, so that the chassis 17 is more than the state in which the receiving port 17 faces the conveyor device 8 at the dust collection position A when the lift arm 22 turns. This is because it rotates to the front side of 2 and faces upward. As shown in FIG. 6, at the dust discharge position B, the hopper 16 is tilted forward from the posture at the dust collection position A, and the receiving port 17 faces upward.

図６に示すようにホッパ１６が塵埃排出位置Ｂに達すると、図７に示すように第３シリンダ３２が伸長する。すると、下回動部材３５、第４シリンダ３３、上回動部材３４が回転すると共に第１スプロケット２９が回転するので、チェーン３１を介して第２スプロケット３０が回転してホッパ１６が右回転方向に回動して受入口１７が下側に向けられる。次に、第３シリンダ３２が最長となると第４シリンダ３３が伸長し、図８に示すように上回動部材３４と共に第１スプロケット２９が回転するので、チェーン３１を介して第２スプロケット３０が回転してホッパ１６はさらに右回転方向に回動し、受入口１７が下に向けられる。これにより図９に示すように回収された塵埃はブラシ式路面清掃車１の後方で待機していた回収用トラックＴや台車等に排出される。このようにホッパ１６の塵埃の排出は支持フレーム９即ちシャシ２側に設けたホッパ回動用シリンダ機構１９によりホッパ１６を回動するので、第３、第４シリンダ３２，３３への配管が短く簡略化され、従来のように配管の干渉を考える必要が減り配管の取り回しが簡単になる。   When the hopper 16 reaches the dust discharge position B as shown in FIG. 6, the third cylinder 32 extends as shown in FIG. Then, since the lower rotating member 35, the fourth cylinder 33, and the upper rotating member 34 rotate and the first sprocket 29 rotates, the second sprocket 30 rotates through the chain 31, and the hopper 16 rotates in the clockwise direction. And the receiving port 17 is directed downward. Next, when the third cylinder 32 is the longest, the fourth cylinder 33 is extended, and the first sprocket 29 is rotated together with the upper rotating member 34 as shown in FIG. By rotating, the hopper 16 further rotates in the clockwise direction, and the receiving port 17 is directed downward. As a result, as shown in FIG. 9, the collected dust is discharged to a collection truck T, a carriage, or the like that is waiting behind the brush type road surface cleaning vehicle 1. As described above, since the hopper 16 is rotated by the hopper rotating cylinder mechanism 19 provided on the support frame 9, that is, the chassis 2 side, the dust discharge from the hopper 16 is short, and the piping to the third and fourth cylinders 32 and 33 is short and simple. Therefore, it is not necessary to consider the interference of piping as in the conventional case, and the piping is simplified.
