Description
本発明は、道路、鉄道などの橋梁における不要なごみである堆積物を掃除するための掃除機に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner for cleaning deposits that are unnecessary dust on bridges such as roads and railways.
橋梁の疲労亀裂などを対象とした定期的な保守点検は、たとえば２年または５年毎に行なわれる。この点検のために、橋梁における堆積物を、予め掃除して除去する必要がある。堆積物は、たとえば風、自動車の車輪などによって運ばれてきた小石、土のほかに、コンクリート破片、鋼材表面の塗料層から剥離した小片、鋼材の錆、植物、枯葉、鳥の巣などがあり、さらに側溝内の水を含んだ土砂など、多くの種類がある。堆積物を掃除すべき場所は、多くの場合、狭い作業空間であり、危険な高所もあり、しかも除去した堆積物を、飛散、落下などすることなく、収集して回収しなければならない。 Periodic maintenance inspections for bridge fatigue cracks are performed, for example, every two or five years. For this inspection, the deposits on the bridge need to be cleaned and removed beforehand. The deposits include, for example, wind, pebbles carried by the wheels of automobiles, soil, as well as concrete debris, debris separated from the paint layer on the surface of steel, rust on steel, plants, dead leaves, bird nests, etc. , And there are many types, such as sediment containing water in the gutter. In many cases, the place where the deposit should be cleaned is a narrow work space and there are dangerous high places, and the removed deposit must be collected and collected without being scattered or dropped.
従来、このような用途に適した作業具は存在しない。作業者は、スコップ、移植こて、刷毛、ブラシ、へらなどを、使用している。このような従来の作業具では、作業性が悪く、高所での取扱いは危険なこともあり、除去した堆積物の回収は困難である。 Conventionally, there is no work implement suitable for such an application. Workers use scoops, implant trowels, brushes, brushes, spatulas, and the like. Such a conventional work tool has poor workability and may be dangerous to handle at a high place, and it is difficult to collect the removed deposit.
本発明の目的は、狭い作業空間であっても、良好な作業性で、掃除をして、橋梁の堆積物を収集して回収することができる掃除機を提供することである。 An object of the present invention is to provide a vacuum cleaner capable of performing cleaning with good workability even in a narrow work space, and collecting and collecting deposits on a bridge .

本件明細書中、たとえば前方、後方、上方、下方などの方向は、吸込み装置の構成を説明する便宜のためにのみ使用され、特定の構成、動作および操作を限定することを、意図していない。本発明は、吸込み装置が使用操作される各種の態様に拘らず、請求項において便宜のためにのみ使用された前後方向、上下方向などの方向によって定義された構成自体である。一例を述べると、前方とは、吸込み装置の操作部材を手で掴んだ作業者が、たとえば橋梁の床組、軌道や路面などの上面の堆積物を、掻き取って、基板へすくい取り、基板上に載せる典型的な使用態様において、吸込み装置を移動操作する下流であり、たとえば後述の右側面図である図６、図１９、図２６の左方であり、後方とは、吸込み装置を移動操作する上流である。上方とは、この使用態様において、基板から見て、堆積物が乗載している方向であり、たとえば右側面図である図６、図１９、図２６の上方であり、下方とは、図６、図１９、図２６の下方である。 Directions herein such as forward, backward, upward, downward, etc. are used only for convenience in describing the construction of the suction device and are not intended to limit the particular construction, operation and operation. .. The present invention is the configuration itself defined by the directions such as the front-back direction and the vertical direction, which are used for convenience only in the claims regardless of various modes in which the suction device is used and operated. To describe one example, the front means that an operator who grasps the operating member of the suction device by hand scrapes off the deposits on the upper surface of the floor assembly of the bridge, track, road surface, etc. In a typical usage mode to be placed on the upper side, it is a downstream side of the moving operation of the suction device, for example, the left side of FIGS. 6, 19, and 26 which are right side views to be described later, and “rear” moves the suction device. It is upstream to operate. In this usage mode, the upper side is the direction in which the deposits are mounted when viewed from the substrate, and is, for example, the upper side in FIGS. 6, 19, and 26 which are right side views, and the lower side is the figure. 6, below FIG. 19 and FIG. 26.
本発明によれば、図１３、図２０に示されるように、典型的な使用態様では、作業者は、吸込み装置の操作部材を片方の手で掴んで、たとえば橋梁の床組、軌道や路面などの上面の堆積物を、掻き取って、基板へすくい取り、基板上に載せる作業を良好な作業性で容易に行なうことができる。基板上に載せられた堆積物は、負圧源の吸引力によって、また、作業者が操作部材を手で操作して吸込み装置の後部が下方となるように傾斜することによって、基板の両端部の側板に沿って案内され、吸込み孔から操作部材を経て可撓管から負圧源によって吸引され、収集されて回収される。
操作部材は、後方になるにつれて上方に傾斜した軸線を有し、たとえば橋梁の床組、軌道などの上面から離間する方向に延びるので、作業者は、吸込み装置の操作部材を片方の手で掴みやすい。したがって、たとえば前記上面の堆積物を、掻き取って、基板へすくい取ったり、凸部の延びる軸線方向に吸引する作業を、良好な作業性で容易に行なうことができる。
According to the present invention, as shown in FIGS. 13 and 20, in a typical usage mode, an operator grips the operating member of the suction device with one hand and, for example, a floor assembly of a bridge, a track or a road surface. It is possible to easily scrape off the deposits on the upper surface of the substrate, scoop it on the substrate, and place it on the substrate with good workability. The deposits placed on the substrate are attracted by the suction force of the negative pressure source, and the operator manually operates the operating member to incline so that the rear portion of the suction device is at the lower end. Is guided along the side plate of the, and is sucked from the flexible tube through the operation member through the suction hole by the negative pressure source, and is collected and collected.
Since the operating member has an axis inclined upward toward the rear and extends in a direction away from the upper surface of, for example, the floor assembly of the bridge or track, the operator grips the operating member of the suction device with one hand. Cheap. Therefore, for example, the work of scraping off the deposit on the upper surface and scooping it onto the substrate or sucking it in the axial direction of the projection can be easily performed with good workability.

本発明によれば、図２７に示されるように、側板の上端部が後部でカバー部によって覆われるので、吸込み孔付近で、基板と側板とカバー部とで規定される空間における負圧の絶対値を可及的に大きくすることができる。これによって、基板上の堆積物は、吸込み孔に負圧吸引されて吸込まれやすくなり、比較的大量の堆積物を、および比較的比重の大きい小石などの堆積物を、回収することができる。 According to the present invention, as shown in FIG. 27, the upper end of the side plate is covered by the cover at the rear, so that the absolute negative pressure in the space defined by the substrate, the side plate and the cover is close to the suction hole. The value can be as large as possible. As a result, the deposit on the substrate is easily sucked by being negatively suctioned by the suction hole, and a relatively large amount of deposit and a deposit such as pebbles having a relatively large specific gravity can be collected.

本発明によれば、図３４に示されるように、たとえば橋梁の床組、軌道などの上面から突出した植込みボルト、その他のボルト頭、ナットなどの凸部付近を掃除するにあたり、包囲部材の下部を前記上面に当接した状態で、包囲部材の切欠きが凸部を通過するように、幅方向両側に、すなわち左右両側方（図２９の左右方向、図３３、図３４の紙面に垂直方向）に、往復移動する。これによって、凸部付近が包囲部材の負圧である取入れ空間内にあり、凸部付近の堆積物を、取入れ口から取入れ空間を経て吸込み孔に、容易に吸引されて、除去することができる。前述の従来では、凸部付近の堆積物を除去しにくく、特に凸部に巻き付いている堆積物は、除去しにくかったが、本発明によれば、凸部の延びる軸線方向（図２９、図３３、図３４の上方）に、堆積物を吸引できるので、その掃除の作業性は良好である。 According to the present invention, as shown in FIG. 34, for example, when cleaning the vicinity of a convex portion of a stud such as a floor assembly of a bridge or a track, a stud bolt protruding from the upper surface, other bolt heads, nuts, etc. With the upper surface in contact with the upper surface, so that the notch of the enclosing member passes through the convex portion, that is, on both sides in the width direction, that is, on both the left and right sides (the left and right directions in FIG. 29, the vertical direction to the paper surface in FIGS . 33 and 34 ) . ), move back and forth. As a result, the vicinity of the protrusion is in the intake space where the negative pressure of the surrounding member is present, and the deposit near the protrusion can be easily sucked and removed from the intake through the intake space to the suction hole. .. According to the above-mentioned conventional technique, it is difficult to remove the deposits in the vicinity of the protrusions, and it is particularly difficult to remove the deposits wound around the protrusions. However, according to the present invention, the protrusions extend in the axial direction (FIG. 29, FIG. 33 , the deposit can be sucked up (in the upper part of FIG. 34 ), so that the cleaning workability is good.

The left side view of the suction device 20 appears symmetrical to the right side view.
掃除機１の吸込み装置２０は、前方（図６の左方）に開口し、後部（図６の右方）が可撓管２を介して負圧源３に接続される。吸込み装置２０は、図２〜図５の左右対称に構成される。吸込み装置２０は、前後方向（図６の左右方向）に延びる平板状の基板２１を有する。基板２１の両側部２２、２３には、上方になるにつれて基板２１の幅方向外方（図２の左右方向）に傾斜して立ち上がる側板２４、２５が取付けられる。側板２４、２５には、立上り側板３６、３７が上方に延びて固定される。端板２９は、基板２１の後端部２７に配置され、基板２１から垂直に立上り、基板２１、側板２４、２５および立上り側板３６、３７に固定され、前方に臨んで開口する吸込み孔２８を有する。端板２９には、筒状、たとえば直円筒状の操作部材３１の一端部３４が固定されて吸込み孔２８に連通する。操作部材３１の他端部３５は、可撓管２に着脱可能に気密に接続される。吸込み装置２０は、たとえば、その全体が、鋼、アルミニウムなどの高強度の金属製である。 The suction device 20 of the cleaner 1 is opened forward (left in FIG. 6), and the rear (right in FIG. 6) is connected to the negative pressure source 3 via the flexible tube 2. The suction device 20 is configured symmetrically with respect to FIGS. The suction device 20 has a plate-shaped substrate 21 extending in the front-rear direction (the left-right direction in FIG. 6). Side plates 24 and 25 are attached to both side portions 22 and 23 of the substrate 21 so as to be inclined and rise outward in the width direction of the substrate 21 (left and right direction in FIG. 2) as it goes upward. Standing side plates 36 and 37 extend and are fixed to the side plates 24 and 25, respectively. The end plate 29 is arranged at the rear end portion 27 of the substrate 21, rises vertically from the substrate 21, is fixed to the substrate 21, the side plates 24, 25, and the rising side plates 36, 37, and has a suction hole 28 facing the front and opening. Have. One end 34 of a tubular, for example right cylindrical, operation member 31 is fixed to the end plate 29 and communicates with the suction hole 28. The other end portion 35 of the operation member 31 is detachably and airtightly connected to the flexible tube 2. The suction device 20 is entirely made of high-strength metal such as steel or aluminum.
立上り側板３６、３７は、基板２１の仮想延長面に垂直に、側板２４、２５から上方に連設される。立上り側板３６、３７は、基板２１の前後方向（図６の左右方向）の途中位置から、側方から見て、後方（図６の右方向）になるにつれて高くなる３角形の板状である。 The rising side plates 36 and 37 are vertically provided continuously from the side plates 24 and 25 perpendicular to the virtual extension surface of the substrate 21. The rising side plates 36 and 37 are triangular plate-like shapes that increase from the middle position in the front-rear direction (left-right direction in FIG. 6) of the substrate 21 to the rear (right direction in FIG. 6) when viewed from the side. ..
吸込み装置２０の寸法形状の一例を述べる。図６のように、基板２１の前後方向の長さＬ２１＝１００ｍｍ、基板２１の前端部３９から立上り側板３６までの距離Ｌ３６ａ＝５４ｍｍ（したがって、たとえば、Ｌ３６ａ≒Ｌ２１／２）、操作部材３１の長さＬ３１＝２００ｍｍ、操作部材３１の呼び径φ３８ｍｍ、端板２９の高さＨ２９＝６１ｍｍ、側板２４の基板２１に垂直な高さＨ２４＝１５ｍｍ、図２のように、端板２９の幅Ｗ２９＝８７ｍｍ、基板２１の幅Ｗ２１＝６０ｍｍである。 An example of the size and shape of the suction device 20 will be described. As shown in FIG. 6, the length L21 of the board 21 in the front-rear direction is 100 mm, the distance L36a from the front end portion 39 of the board 21 to the rising side plate 36 is 54 mm (hence, for example, L36a≈L21/2), and the operating member 31 is Length L31=200 mm, nominal diameter φ38 mm of operating member 31, height H29 of end plate 29=61 mm, height H24 of side plate 24 perpendicular to substrate 21=H24=15 mm, width W29 of end plate 29 as shown in FIG. =87 mm and the width W21 of the substrate 21=60 mm.
操作部材３１は、後方（図６の右方）になるにつれて上方に角度θだけ傾斜した軸線３２を有する。角度θは、たとえば１０°〜３０°であり、好ましくは１５°であってもよい。この角度θによって、作業者の堆積物を吸込む作業性が向上される。 The operating member 31 has an axis 32 that is inclined upward by an angle θ as it goes rearward (rightward in FIG. 6). The angle θ may be, for example, 10° to 30°, preferably 15°. This angle θ improves the workability of the worker for sucking the deposit.
作業者は、吸込み装置２０の操作部材３１を片方の手で掴んで、たとえば橋梁の床組、軌道などの上面の堆積物を、掻き取って、基板２１へすくい取り、基板２１上に載せる作業を良好な作業性で容易に行なうことができる。基板２１上に載せられた堆積物は、負圧源３の吸引力によって、また、作業者が操作部材３１を手で操作して吸込み装置２０の後部（図６の右方）が下方となるように傾斜することによって、基板２１の両端部の側板２４、２５および立上り側板３６、３７に沿って案内され、吸込み孔２８から操作部材３１を経て可撓管２から負圧源３によって吸引され、収集されて回収される。 The operator grips the operating member 31 of the suction device 20 with one hand and scrapes off the deposits on the upper surface of the floor assembly of the bridge, tracks, etc., scoops it onto the substrate 21, and places it on the substrate 21. Can be easily performed with good workability. The deposit placed on the substrate 21 is lowered by the suction force of the negative pressure source 3 or by the operator manually operating the operation member 31 so that the rear portion (right side in FIG. 6) of the suction device 20 is downward. By inclining as described above, the base plate 21 is guided along the side plates 24 and 25 and the rising side plates 36 and 37 at both ends thereof, and is sucked by the negative pressure source 3 from the flexible tube 2 through the operation member 31 through the suction hole 28. , Collected and collected.
端板２９は、前述のように、基板２１に垂直であるので、吸込み孔２８の内径よりも大きく、したがって吸込み孔２８へ入り込むことができない外形を有する堆積物、たとえば小石などは、吸込み孔２８に臨んで吸引されて、吸込み孔２８の外方で、基板２１上で端板２９に当接したままで静止する。したがって、そのような外形が大きい堆積物は、操作部材３１の目詰りを生じさせることはない。作業者は、端板２９に吸引当接したままで静止している堆積物を、手で掴み出して取り除き、掃除を続行することができる。したがって、掃除の途中で、目詰りに起因して負圧源３を休止せず、連続運転が可能であり、能率がよい。 Since the end plate 29 is perpendicular to the substrate 21 as described above, the deposit having an outer shape that is larger than the inner diameter of the suction hole 28 and therefore cannot enter the suction hole 28, such as a pebbles, is sucked into the suction hole 28. Is sucked in front of the suction hole 28, and is stationary outside the suction hole 28 while being in contact with the end plate 29 on the substrate 21. Therefore, such a deposit having a large outer shape does not cause clogging of the operating member 31. The operator can continue to carry out the cleaning by grasping and removing the stationary deposits that are still in contact with the end plate 29 by suction. Therefore, during cleaning, the negative pressure source 3 is not stopped due to clogging, and continuous operation is possible, which is efficient.

図８に示されるとおり、堆積物収納袋８は、容器６内に取外し可能に、容器６の底面と内周壁とに沿って、上部が外向きに容器６の上部にかぶさって配置される。堆積物吸引手段の取付けフランジ１３は、容器６の上部に堆積物収納袋８の上部を介在して配置される。有底筒状フイルタ１１は、通気性を有し、上部が取付けフランジ１３に支持され、堆積物収納袋８の内面との間に堆積物回収空間１６を形成する外面を有し、堆積物回収空間１６内で容器６の底面よりも上方に間隙をあけて配置される下部を有する。

The length and nominal diameter of the operating member 71 are the same as those of the operating member 31 described above, the height H69 of the end plate 69=42 mm, the height H64 of the side plate 64 perpendicular to the substrate 61 H15=15 mm, and the front inclined portion 83. The height H83 is 9 mm, the width W69 of the end plate 69 is 90 mm, and the width W61 of the substrate 61 is 60 mm as shown in FIG.
端板６９は、基板６１の後端部に配置され、基板６１から垂直に立上り、基板６１、側板６４、６５、立上り側板７６、７７およびカバー部８１に固定され、前方に臨んで開口する吸込み孔６８を有する。端板６９には、筒状、たとえば直円筒状の操作部材７１の一端部７４が固定されて吸込み孔６８に連通する。操作部材７１の他端部７５は、可撓管２に着脱可能に気密に接続される。操作部材７１は、後方（図１９の右方）になるにつれて上方に角度θだけ傾斜した軸線７２を有する。 The end plate 69 is arranged at the rear end portion of the substrate 61, rises vertically from the substrate 61, is fixed to the substrate 61, the side plates 64 and 65, the rising side plates 76 and 77, and the cover portion 81, and is a suction opening that faces the front and opens. It has holes 68. One end portion 74 of a cylindrical, for example, right cylindrical operation member 71 is fixed to the end plate 69 and communicates with the suction hole 68. The other end portion 75 of the operation member 71 is detachably and airtightly connected to the flexible tube 2.

The cover portion 81 is connected to an intake port 86 that faces the front and is open. The space 82 maximizes the absolute value of the negative pressure near the suction hole 68. As a result, at the front end portion 79 of the substrate 61, for example, the deposit adhered to the roadbed of the railway track can be peeled off and scooped onto the substrate 61. The deposit on the substrate 61 is easily sucked by being negatively sucked into the suction hole 68 from the intake port 86 through the space 82, so that a relatively large amount of deposit and a deposit such as pebbles having a relatively large specific gravity are collected. , Can be collected.

The rising side plates 106 and 107 are plate-shaped in the shape of a right-angled triangle that becomes higher toward the rear (rightward in FIG. 26) when viewed from the side.
立上り側板１０６、１０７の上端部には、カバー部１１１が取付けられる。カバー部１１１は、基板９１を覆う。 A cover portion 111 is attached to the upper ends of the rising side plates 106 and 107. The cover portion 111 covers the substrate 91.
端板９９は、基板９１の後端部に配置され、基板９１から垂直に立上り、基板９１、側板９４、９５、立上り側板１０６、１０７およびカバー部１１１に固定され、前方に臨んで開口する吸込み孔９８を有する。端板９９には、筒状、たとえば直円筒状の操作部材１０１の一端部１０４が固定されて吸込み孔９８に連通する。操作部材１０１の他端部１０５は、可撓管２に着脱可能に気密に接続される。操作部材１０１は、後方（図２６の右方）になるにつれて上方に角度θだけ傾斜した軸線１０２を有する。 The end plate 99 is arranged at the rear end of the substrate 91, rises vertically from the substrate 91, is fixed to the substrate 91, the side plates 94 and 95, the rising side plates 106 and 107, and the cover portion 111, and is a suction opening that faces the front and opens. It has holes 98. One end portion 104 of a tubular, for example, right cylindrical, operation member 101 is fixed to the end plate 99 and communicates with the suction hole 98. The other end 105 of the operation member 101 is detachably and airtightly connected to the flexible tube 2. The operation member 101 has an axis line 102 that is inclined upward by an angle θ as it goes rearward (rightward in FIG. 26).
吸込み装置９０の寸法形状の一例を述べる。図２６のように、側板９４の前後方向の長さＬ９４＝１００ｍｍ、基板９１の端板９９から前端部１０９までの距離Ｌ９１＝３５ｍｍ（したがって、たとえば、Ｌ９１≒Ｌ９４／３）、操作部材１０１の長さと呼び径とは前述の操作部材３１と同一値であり、端板９９の高さＨ９９＝６１ｍｍ、側板９４の基板９１に垂直な高さＨ９４＝１５ｍｍ、図２２のように、端板９９の幅Ｗ９９＝９０ｍｍ、基板９１の幅Ｗ９１＝６０ｍｍである。 An example of the size and shape of the suction device 90 will be described. As shown in FIG. 26, the length L94 of the side plate 94 in the front-rear direction is 100 mm, the distance L91 from the end plate 99 of the substrate 91 to the front end 109 is L91=35 mm (hence, L91≈L94/3), and the operating member 101 is The length and the nominal diameter are the same values as those of the operation member 31 described above, and the height H99 of the end plate 99=61 mm, the height H94 of the side plate 94 perpendicular to the substrate 91 H15=15 mm, and as shown in FIG.

カバー部１１１は、基板９１、側板９４、９５および立上り側板１０６、１０７とともに、空間１１２を規定する。カバー部１１１は、前方および下方に臨んで開放する取入れ口１１６に連なる。空間１１２は、除去すべき堆積物の全体を収納するので、吸込み孔９８付近における負圧の絶対値を可及的に大きくする。これによって、基板９１上の堆積物は、取入れ口１１６から空間１１２を経て吸込み孔９８に負圧吸引されて吸込まれやすくなり、比較的大量の堆積物を、および比較的比重の大きい小石などの堆積物を、回収することができる。吸込み装置９０のその他の構成と動作、操作などは、前述の実施の形態に類似する。 The cover portion 111 defines a space 112 together with the substrate 91, the side plates 94 and 95, and the rising side plates 106 and 107. The cover portion 111 is connected to an intake port 116 that is open facing the front and the bottom. Since the space 112 stores the entire deposit to be removed, the absolute value of the negative pressure in the vicinity of the suction hole 98 is made as large as possible. As a result, the deposits on the substrate 91 are easily sucked by negative pressure from the intake port 116 through the space 112 and into the suction holes 98, so that a relatively large amount of deposits and pebbles having a relatively large specific gravity are absorbed. The deposit can be collected. Other configurations, operations, operations, etc. of the suction device 90 are similar to those of the above-described embodiment.
図２７は、本発明の実施の他の形態の吸込み装置１１８の斜視図である。この吸込み装置１１８は、前述の吸込み装置９０に類似し、対応する部分には、同一の参照符を付す。注目すべきは、端板９９に取付けられる操作部材１０１ａの一端部１０４ａ付近は、他端部１０５側になるにつれて軸直角断面の断面積が小さくなる筒状に形成される。この一端部１０４ａ付近は、操作部材１０１ａの軸線１０２の上方に膨出した形状を有する。この実施の形態によれば、吸込み孔９８からの堆積物は、円滑に操作部材１０１ａ内へ導かれて回収される。図２１〜２６における側板９４、９５は、この実施の形態では、省略される。吸込み装置１１８のその他の構成と動作、操作などは、前述の実施の形態に類似する。 FIG. 27 is a perspective view of a suction device 118 according to another embodiment of the present invention. The suction device 118 is similar to the suction device 90 described above, and corresponding parts bear the same reference numerals. It should be noted that the vicinity of one end 104a of the operation member 101a attached to the end plate 99 is formed in a tubular shape in which the cross-sectional area of the cross section perpendicular to the axis becomes smaller toward the other end 105 side. The vicinity of the one end 104a has a shape that bulges above the axis 102 of the operation member 101a.

The side plates 94 and 95 in FIGS. 21 to 26 are omitted in this embodiment. Other configurations, operations, operations and the like of the suction device 118 are similar to those of the above-described embodiment.
図２８は本発明の実施の他の形態の掃除機１の吸込み装置１２０の斜視図であり、図２９は吸込み装置１２０の正面図であり、図３０は吸込み装置１２０の背面図であり、図３１は吸込み装置１２０の平面図であり、図３２は吸込み装置１２０の底面図であり、図３３は吸込み装置１２０の右側面図である。吸込み装置１２０の左側面図は、右側面図と対称にあらわれる。この吸込み装置１２０は、前述の吸込み装置に類似し、対応する部分の説明を簡略に、または省略する。 28 is a perspective view of the suction device 120 of the vacuum cleaner 1 according to another embodiment of the present invention, FIG. 29 is a front view of the suction device 120, and FIG. 30 is a rear view of the suction device 120. 31 is a plan view of the suction device 120, FIG. 32 is a bottom view of the suction device 120, and FIG. 33 is a right side view of the suction device 120. The left side view of the suction device 120 appears symmetrical to the right side view. The suction device 120 is similar to the suction device described above, and the description of the corresponding parts will be simplified or omitted.
掃除機１の吸込み装置１２０は基本的に、包囲部材１２１と包囲部材１２１の上部に連なる筒状、たとえば直円筒状の操作部材１３１とを含み、操作部材１３１が可撓管２を介して負圧源３に接続される。吸込み装置１２０は、図２９〜図３２の左右対称に構成され、包囲部材１２１は、図３３の左右対称に構成される。 The suction device 120 of the vacuum cleaner 1 basically includes an enclosing member 121 and a tubular, for example, right-cylindrical operating member 131 connected to an upper portion of the enclosing member 121, and the operating member 131 is connected via the flexible tube 2 via the flexible tube 2. It is connected to the pressure source 3. The suction device 120 is configured symmetrically with respect to FIGS. 29 to 32, and the surrounding member 121 is configured symmetrically with respect to FIG. 33.
包囲部材１２１は、周壁１２４と、周壁１２４の上部を塞ぐ端壁１２５とを有する。周壁１２４は、下方に臨む取入れ口１２６を形成し、この取入れ口１２６に連なって端壁１２５とともに取入れ空間１２７を形成する。端壁１２５には、取入れ空間１２７に開口する吸込み孔１２８が形成される。操作部材１３１の一端部１３３は、端壁１２５に固着され、吸込み孔１２８に連通する。操作部材１３１の他端部１３４は、可撓管２に着脱可能に気密に接続される。操作部材１３１は、後方（図３３の右方）になるにつれて上方に角度θ１だけ傾斜した軸線１３２を有する。角度θ１は、たとえば３０°〜６０°であってもよく、好ましくは４５°に選ばれる。 The surrounding member 121 has a peripheral wall 124 and an end wall 125 that closes an upper portion of the peripheral wall 124. The peripheral wall 124 forms an intake port 126 that faces downward, and is connected to the intake port 126 to form an intake space 127 together with the end wall 125. A suction hole 128 that opens into the intake space 127 is formed in the end wall 125. One end 133 of the operating member 131 is fixed to the end wall 125 and communicates with the suction hole 128. The other end portion 134 of the operation member 131 is detachably and airtightly connected to the flexible tube 2. The operation member 131 has an axis line 132 that is inclined upward by an angle θ1 toward the rear (right side in FIG. 33). The angle θ1 may be, for example, 30° to 60°, and is preferably selected to be 45°.
周壁１２４では、前板１３５ａと後板１３５ｂとにそれぞれ関連して、参照符に添え字ａ、ｂを付し、総括的に数字のみで示す。側板１３６は、斜め側板１３７、１３８を介して、前板１３５ａと後板１３５ｂとに連なって固定される。周壁１２４の側板１３６は、図３３に明らかに示されるように、下方から上方になるにつれて前後方向（図３３の左右方向）の幅が大きくなるように構成され、したがって、その内部の取入れ空間１２７は下方から上方になるにつれて拡がって形成される。 In the peripheral wall 124, reference numerals are suffixed with a and b in association with the front plate 135a and the rear plate 135b, respectively, and are generally shown only by numbers. The side plate 136 is fixed to the front plate 135a and the rear plate 135b in a continuous manner via diagonal side plates 137 and 138. As shown clearly in FIG. 33, the side plate 136 of the peripheral wall 124 is configured such that the width in the front-rear direction (the left-right direction in FIG. 33) increases from the lower side to the upper side, so that the intake space 127 inside thereof is formed. Is formed to spread from the bottom to the top.
包囲部材１２１の周壁１２４における側板１３６および斜め側板１３７、１３８から成る両側部には、下方に開放した逆Ｕ字状の切欠き１４１が形成される。 An inverted U-shaped notch 141 that opens downward is formed on both sides of the peripheral wall 124 of the enclosing member 121, the side plate 136 and the diagonal side plates 137 and 138.
吸込み装置１２０を使用して作業者が堆積物回収作業を、図２８を参照して説明する。作業者は、片方の手で操作部材１３１を掴んだ状態で、たとえば橋梁の床組、軌道などの上面１４２から突出した植込みボルト、その他のボルト頭、ナットなどの凸部１４３付近を掃除するにあたり、包囲部材１２１の下部を上面１４２に当接した状態で、包囲部材１２１の切欠き１４１が凸部１４３を通過するように、幅方向１４５の両側に、すなわち左右両側方（図２９の左右方向、図３３の紙面に垂直方向）に、往復移動する。これによって、凸部１４３およびその付近を、包囲部材１２１の負圧である取入れ空間１２７内に存在させる。したがって、凸部１４３付近の堆積物を、容易に取入れ口１２６から取入れ空間１２７を経て吸込み孔１２８に吸引させて、除去することができる。前述の従来では、凸部１４３付近の堆積物を除去しにくく、特に凸部１４３に巻き付いている堆積物は、除去しにくかったが、本発明によれば、凸部１４３の延びる軸線方向（図２８、図２９、図３３の上方）に、堆積物を吸引できるので、その掃除の作業性は良好である。 A worker using the suction device 120 to collect deposits will be described with reference to FIG. 28. When the operator holds the operation member 131 with one hand, for example, when cleaning the vicinity of the convex portion 143 such as a stud such as a floor set of a bridge or a track or the like, an stud bolt protruding from the upper surface 142, other bolt heads, nuts or the like. While the lower part of the surrounding member 121 is in contact with the upper surface 142, the notches 141 of the surrounding member 121 pass through the convex portions 143, that is, on both sides in the width direction 145, that is, on both left and right sides (left and right directions in FIG. 29). , In the direction perpendicular to the paper surface of FIG. 33). As a result, the convex portion 143 and its vicinity are made to exist in the intake space 127 that is the negative pressure of the surrounding member 121. Therefore, the deposit in the vicinity of the convex portion 143 can be easily removed from the intake port 126 through the intake space 127 and the suction hole 128. In the above-mentioned conventional technique, it is difficult to remove the deposits in the vicinity of the protrusions 143, and it is particularly difficult to remove the deposits wound around the protrusions 143. However, according to the present invention, the axial direction in which the protrusions 143 extend (see FIG. 28, the upper part of FIG. 29, and FIG. 33), the deposit can be sucked, so that the cleaning workability is good.
取入れ空間１２７は、その下部の取入れ口１２６および切欠き１４１から上方になるにつれて拡がって形成されるので、凸部１４３付近などの堆積物を、比較的狭い取入れ口１２６および切欠き１４１から取入れ空間１２７内へ、大きな吸引力で、取入れて収納することができる。取入れ空間１２７は、その上部で拡がって形成されるので、取入れ空間１２７内に、一旦、取入れられた堆積物は、吸込み孔１２８へ連続して順次的に円滑に吸込まれて導かれ、したがって、堆積物によって吸込み孔１２８が目詰まりを生じることはない。 The intake space 127 is formed so as to spread upward from the intake port 126 and the notch 141 at the lower part thereof, so that deposits such as the vicinity of the convex portion 143 are taken in from the relatively narrow intake port 126 and the notch 141. It can be taken in and stored in 127 with a large suction force. Since the intake space 127 is formed so as to expand at the upper portion thereof, the deposits once taken into the intake space 127 are continuously and smoothly sucked and guided to the suction holes 128, and thus, The suction hole 128 is not clogged by the deposit.
吸込み装置９０の寸法形状の一例を述べる。図３３のように、端壁１２５の前後方向の長さＬ１２５＝６２ｍｍ、切欠き１４１の下端部の前後方向の長さＬ１４１＝２８ｍｍ、前板１３５ａ、１３５ｂの高さＨ１３５＝９０ｍｍ、切欠き１４１の高さＨ１４１＝３０ｍｍ、操作部材１３１の長さと呼び径とは前述の操作部材３１と同一値であり、図２９のように、前板１３５の幅Ｗ１３５＝ｍｍ、端壁１２５の幅Ｗ１２５＝６２ｍｍである。 An example of the size and shape of the suction device 90 will be described. As shown in FIG. 33, the length L125 in the front-rear direction of the end wall 125=62 mm, the length L141=28 mm in the front-rear direction of the lower end of the notch 141, the height H135 of the front plates 135a and 135b=90 mm, the notch 141 H141=30 mm, the length and nominal diameter of the operating member 131 are the same values as those of the operating member 31 described above, and as shown in FIG. 29, the width W135=mm of the front plate 135 and the width W125=of the end wall 125= It is 62 mm.

This suction device 148 is similar to the suction device 120 previously described, and corresponding parts bear the same reference numerals. It should be noted that the vicinity of the one end 133a of the operation member 131a attached to the end wall 125 of the surrounding member 121a swells as shown in FIG. It is formed in a cylindrical shape having a small area, for example, a hollow truncated cone shape having a small diameter on the other end portion 134 side. According to this embodiment, the deposits from the suction holes 128 are smoothly guided into the operation member 131a and collected. Other configurations, operations, operations, etc. of the suction device 148 are similar to those of the above-described embodiment.

さらに、本発明は、従来の電車の床下の気吹き作業では、粉塵が周囲に散乱して充分な集塵効果が得られていないという問題を解決するために、従来の気吹き方法でなく、本発明に従う吸込み装置を備える多機能掃除機を活用して、粉塵を吸い取るために、実施することができる。 Furthermore, the present invention, in the conventional under-floor air blowing work of the train, in order to solve the problem that the dust is scattered to the surroundings and a sufficient dust collection effect is not obtained, not the conventional air blowing method, A multifunctional vacuum cleaner with a suction device according to the invention can be utilized to suck dust.
