Description

本発明は、路面上の堆積物（堆積粉）を清掃除去するための清掃装置に関するもので、特にコークス炉の炉頂部に堆積した石炭粉を清掃除去するのに好適な清掃装置に関するものである。 The present invention relates to a cleaning device for cleaning and removing deposits (deposited powder) on the road surface, and particularly to a cleaning device suitable for cleaning and removing coal powder deposited on the top of a coke oven. ..

コークス工場では、炉内に石炭を装入する装炭車からの石炭粉の漏れや、石炭貯蔵庫からの石炭粉の漏れなどにより、コークス炉の炉頂部に石炭粉（落粉）が堆積する。この堆積した石炭粉を放置すると、石炭粉中の硫黄成分等が上昇管などの金属構造物の腐食を促進させ、また、周囲に飛散して環境に悪影響を与えることから、炉体保護や粉塵飛散防止を目的として、炉頂部に堆積した石炭粉の清掃除去が行われる。しかし、炉頂部に堆積した石炭粉の清掃除去作業は、高温・粉塵環境下で行われる重筋作業であり、熱中症や粉塵吸引の恐れがある危険な作業でもある。
石炭粉のような堆積物の清掃作業を行う清掃方法ないし装置として、例えば、特許文献１には、清掃対象物（堆積物）をドーザー部（清掃部材）で押してかき集める自走式の清掃装置が開示されている。 At the coke mill, coal powder (falling powder) is deposited on the top of the coke oven due to leakage of coal powder from a coal loading vehicle that charges coal into the furnace and leakage of coal powder from a coal storage. If this accumulated coal powder is left unattended, the sulfur component in the coal powder accelerates the corrosion of metal structures such as rising pipes, and it scatters around and adversely affects the environment. Coal powder accumulated on the top of the furnace is cleaned and removed for the purpose of preventing scattering. However, the work of cleaning and removing the coal powder accumulated on the top of the furnace is a heavy-duty work performed in a high temperature and dust environment, and is also a dangerous work that may cause heat stroke or dust suction.
As a cleaning method or device for cleaning deposits such as coal powder, for example, Patent Document 1 includes a self-propelled cleaning device that pushes and collects objects (deposits) to be cleaned by a dozer portion (cleaning member). It has been disclosed.

したがって本発明の目的は、以上のような従来技術の課題を解決し、路面の凹凸に関わりなく、路面上の堆積物を確実かつ効率的にかき集めることができる清掃装置を提供することにある。また、本発明の他の目的は、そのような清掃装置を用いたコークス炉の炉頂部清掃方法を提供することにある。 However, since the cleaning device shown in Patent Document 1 cannot change the relative position of the dozer portion with respect to the main body portion of the cleaning device, for example, when the main body portion rides on the convex portion of the road surface during traveling. There is a problem that the lower end surface of the dozer portion floats from the road surface (running surface) and the deposits on the road surface cannot be sufficiently collected by the dozer portion.
Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a cleaning device capable of reliably and efficiently collecting deposits on the road surface regardless of the unevenness of the road surface.

図１～図３は、本発明の第一の形態の清掃装置の一構成例を示す概念図であり、図１は側面図、図２は正面図、図３は平面図である。
この清掃装置は、路面上を走行可能な装置本体１と、この装置本体１に保持機構３を介して上下動自在に保持される清掃部材２を備えている。
装置本体１は自走式の台車であり、車体１１、走行用の車輪１２a，１２bおよび駆動・操舵機構（図示せず）などを備えている。
本発明の清掃装置は、装置本体１が路面Ａを走行し、それに伴って清掃部材２が路面Ａ上の堆積物ｄ（堆積粉）をかき集めることにより路面Ａを清掃するものであり、したがって、装置本体１は堆積物（堆積粉）の吸引機構や吸引した堆積物の貯留機構などは備えていない。 1 to 3 are conceptual views showing a configuration example of a cleaning device according to the first aspect of the present invention, FIG. 1 is a side view, FIG. 2 is a front view, and FIG. 3 is a plan view.
This cleaning device includes a device main body 1 that can travel on a road surface, and a cleaning member 2 that is vertically movablely held by the device main body 1 via a holding mechanism 3.
The main body 1 of the device is a self-propelled bogie, and includes a vehicle body 11, wheels 12a and 12b for traveling, a drive / steering mechanism (not shown), and the like.
In the cleaning device of the present invention, the device main body 1 runs on the road surface A, and the cleaning member 2 cleans the road surface A by collecting the deposit d (deposited powder) on the road surface A. The main body 1 of the apparatus does not have a mechanism for sucking sediment (deposited powder) or a mechanism for storing the sucked sediment.

清掃部材２は、下端部が路面Ａに接地した状態で装置本体１が走行することにより路面上の堆積物ｄ（堆積粉）をかき集める部材であり、本構成例では、装置本体１の前面にその幅方向に沿って配置されるドーザー部材２０で構成されている。
このドーザー部材２０の本体部は、例えば金属製の板状の部材などで構成され、下端部は、路面上の堆積物をかき集めやすくするため、ゴム製のスクレーパや樹脂製または金属製のブラシなどで構成されることが好ましい。具体的には、石炭粉のように粒径およびかさ密度の小さい堆積物（通常、石炭粉は粒径１ｍｍ以下、嵩密度１．０ｇ／ｃｍ^３以下）をかき集める場合には、ドーザー部材２０の下端部はスクレーパで構成するのが好ましいが、堆積物の粒径や嵩密度によってはブラシなどで構成してもよい。
また、清掃部材２としては、本構成例のドーザー部材２０のような壁状の部材が好ましいが、装置本体１が走行することにより路面上の堆積物をかき集める部材であればよく、例えば、固定式や回転式のブラシなどでもよい。また、ブラシとドーザー部材を組み合わせたものでもよい。 The cleaning member 2 is a member that collects deposits d (deposited powder) on the road surface by traveling the apparatus main body 1 with the lower end portion in contact with the road surface A. In this configuration example, the cleaning member 2 is on the front surface of the apparatus main body 1. It is composed of a dozer member 20 arranged along the width direction.
The main body of the dozer member 20 is made of, for example, a metal plate-shaped member, and the lower end thereof is a rubber scraper, a resin or metal brush, or the like in order to easily collect deposits on the road surface. It is preferably composed of. Specifically, in the case of collecting deposits having a small particle size and bulk density such as coal powder (usually, coal powder has a particle size of 1 mm or less and a bulk density of 1.0 g / cm ³ or less), the dozer member 20 is used. The lower end is preferably made of a scraper, but may be made of a brush or the like depending on the particle size and bulk density of the deposit.
Further, as the cleaning member 2, a wall-shaped member such as the dozer member 20 of this configuration example is preferable, but any member may be used as long as it is a member that collects deposits on the road surface by traveling the apparatus main body 1, for example, fixing. It may be a formula or a rotary brush. Further, a combination of a brush and a dozer member may be used.

保持機構３も、清掃部材２を装置本体１に上下動自在（フリーに上下動可能）に保持できるものであれば、その種類を問わないが、通常は、後述する実施形態のようなスライド式のガイド機構などが用いられる。
清掃部材２は、装置本体１に上下動自在に保持されることにより、その自重により下端部が路面Ａに接地した状態（清掃部材２の下端面が路面Ａと隙間なく接した状態）に保たれつつ、清掃する路面Ａの凹凸に応じてフリーに上下動する。すなわち、路面の凹凸に倣って且つ装置本体１の凹凸通過時の走行姿勢の変化に応じてフリーに上下動する。なお、清掃部材２がブラシの場合であっても、同様である。 The holding mechanism 3 may be of any type as long as it can hold the cleaning member 2 in the device main body 1 so as to be vertically movable (freely movable up and down), but is usually a slide type as in the embodiment described later. The guide mechanism of is used.
The cleaning member 2 is held in a state where the lower end portion is in contact with the road surface A due to its own weight by being held vertically by the apparatus main body 1 (a state in which the lower end surface of the cleaning member 2 is in contact with the road surface A without a gap). While dripping, it moves up and down freely according to the unevenness of the road surface A to be cleaned. That is, it moves up and down freely according to the change in the traveling posture when the device main body 1 passes through the unevenness of the road surface. The same applies even when the cleaning member 2 is a brush.

図４は、図１～図３の清掃装置の路面清掃状況と、この路面清掃時における清掃部材２の動き（上下動）を例示したものであり、路面Ａを清掃している清掃装置の進行方向に凸部ａがある場合、平坦部を清掃している図４（ａ）の状態から、図４（ｂ）のように清掃部材２が凸部ａに倣って上下動する（上下方向にスライド移動する）ことで、図４（ｃ）のように凸部ａを乗り越え、次いで、図４（ｄ）のように装置本体１が凸部ａに乗り上げた時にも、図４（ｅ）のように清掃部材２が下方にスライド移動して、下端部が路面Ａに接地する。このように、清掃部材２は清掃する路面Ａの凹凸に応じて上下動し、その自重により下端部が路面Ａに接地した状態に保たれる。 FIG. 4 illustrates the road surface cleaning status of the cleaning devices of FIGS. 1 to 3 and the movement (vertical movement) of the cleaning member 2 during the road surface cleaning, and the progress of the cleaning device cleaning the road surface A. When there is a convex portion a in the direction, the cleaning member 2 moves up and down following the convex portion a as shown in FIG. 4 (b) from the state of FIG. 4 (a) in which the flat portion is being cleaned (in the vertical direction). By sliding), the device body 1 gets over the convex portion a as shown in FIG. 4 (c), and then when the apparatus main body 1 rides on the convex portion a as shown in FIG. 4 (d), the convex portion a is also shown in FIG. 4 (e). The cleaning member 2 slides downward so that the lower end portion touches the road surface A.

図１１および図１２は、本発明の第二の形態の清掃装置の一構成例を示す概念図であり、図１１は側面図、図１２は正面図である。
この清掃装置は、清掃部材２が保持機構３を介して装置本体１に上下動自在で且つ装置本体幅方向に対して傾動自在に保持されるものであり、その他の構成は図１～図３の清掃装置と同様である。清掃部材２は、図１２に示すように、装置本体幅方向の中央位置ｐを回動中心として傾動自在であることが好ましい。
保持機構３は、清掃部材２を装置本体１に上下動自在（フリーに上下動可能）で且つ装置本体幅方向に対して傾動自在（フリーに傾動可能）に保持できるものであれば、その種類を問わないが、通常は、後述する実施形態のようなスライド式のガイド機構や、スライド式のガイド機構と回転機構を組み合わせたものなどが用いられる。 11 and 12 are conceptual views showing a configuration example of a cleaning device according to a second aspect of the present invention, FIG. 11 is a side view, and FIG. 12 is a front view.
In this cleaning device, the cleaning member 2 is held by the device main body 1 via the holding mechanism 3 so as to be vertically movable and tiltable with respect to the width direction of the device main body, and other configurations are shown in FIGS. 1 to 3.

As shown in FIG. 12, the cleaning member 2 is preferably tiltable with the center position p in the width direction of the apparatus main body as the center of rotation.
The type of the holding mechanism 3 is such that the cleaning member 2 can be held in the device body 1 so as to be vertically movable (freely movable up and down) and tiltable in the width direction of the device body (freely tiltable). However, usually, a slide-type guide mechanism as in the embodiment described later, or a combination of a slide-type guide mechanism and a rotation mechanism is used.

清掃部材２は、装置本体１に上下動自在で且つ装置本体幅方向に対して傾動自在に保持されることにより、その自重により下端部が路面Ａに接地した状態（清掃部材２の下端面が路面Ａと隙間なく接した状態）に保たれつつ、清掃する路面Ａの凹凸に応じてフリーに上下動または／および装置本体幅方向に対して傾動する。すなわち、路面の凹凸に倣って且つ装置本体１の凹凸通過時の走行姿勢の変化に応じて、フリーに上下動または／および装置本体幅方向に対して傾動する。この場合、清掃部材２は、路面Ａの凹凸に応じて任意の傾斜角に傾動することができる。 The cleaning member 2 is held by the device main body 1 so as to be vertically movable and tiltable with respect to the width direction of the device main body, so that the lower end portion thereof is in contact with the road surface A due to its own weight (the lower end surface of the cleaning member 2 is in contact with the road surface A). While being maintained in contact with the road surface A without a gap), it freely moves up and down or / or tilts in the width direction of the device body according to the unevenness of the road surface A to be cleaned. That is, it freely moves up and down or / or tilts in the width direction of the device body according to the change in the traveling posture when the device body 1 passes through the unevenness of the road surface. In this case, the cleaning member 2 can be tilted to an arbitrary inclination angle according to the unevenness of the road surface A.

図１３は、図１１および図１２の清掃装置の路面清掃状況と、この路面清掃時における清掃部材２の動き（上下動および装置本体幅方向に対する傾動）を例示したものであり、路面Ａを清掃している清掃装置の進行方向に凸部ａがある場合、平坦部を清掃している図１３（ａ）の状態から、清掃部材２が凸部ａに倣って上下動（上下方向にスライド移動）し且つ装置本体幅方向に対して傾動することで凸部ａを乗り越え（上下動に関しては図４（ｂ）～（ｃ）を参照）、次いで、図１３（ｂ）のように装置本体１が凸部ａに乗り上げた時に、図１３（ｃ）のように清掃部材２が下方にスライド移動するとともに、装置本体幅方向に対して傾動し、下端部が路面Ａに接地する。このように、清掃部材２は清掃する路面Ａの凹凸に応じて上下動または／および装置本体幅方向に対して傾動して、その自重により下端部が路面Ａに接地した状態に保たれる。
本構成例においても、例えば、図５および図６と同様の形態で付勢手段４（バネ機構４０）を設けることができる。 FIG. 13 illustrates the road surface cleaning situation of the cleaning device of FIGS. 11 and 12 and the movement of the cleaning member 2 (vertical movement and tilting with respect to the width direction of the device main body) during the road surface cleaning, and cleans the road surface A. When there is a convex portion a in the traveling direction of the cleaning device, the cleaning member 2 moves up and down (slides in the vertical direction) following the convex portion a from the state of FIG. 13A in which the flat portion is being cleaned. ) And overcomes the convex portion a by tilting in the width direction of the device body (see FIGS. 4 (b) to (c) for vertical movement), and then the device body 1 as shown in FIG. 13 (b). When the cleaning member 2 rides on the convex portion a, the cleaning member 2 slides downward and tilts in the width direction of the main body of the apparatus as shown in FIG. 13 (c), and the lower end portion touches the road surface A. In this way, the cleaning member 2 moves up and down or / or tilts with respect to the width direction of the main body of the apparatus according to the unevenness of the road surface A to be cleaned, and the lower end portion thereof is kept in contact with the road surface A due to its own weight.

In this embodiment, the guide portion 30 of the holding mechanism 3 of the above (ii) is configured by the guide hole 30x, and the slide member 31 that engages with the guide portion 30 is configured by the slide pin 31x.
The basic configurations of the apparatus main body 1, the cleaning member 2, and the holding mechanism 3 are as described with reference to FIGS. 1 to 3 and FIGS. 11 and 12.
On the front surface of the apparatus main body 1, a constituent member 10 for providing the holding mechanism 3 is arranged along the width direction of the apparatus main body, and is supported by the apparatus main body 1 by the support member 14.

保持機構３は、装置本体幅方向に沿って配され、清掃部材２と装置本体１の構成部材１０との間に介在する中間部材３２と、清掃部材２の装置本体幅方向で間隔をおいた少なくとも２箇所に、上下方向に沿って設けられるガイド孔３０x（ガイド部３０）と、中間部材３２に装置本体幅方向で間隔をおいて設けられ、清掃部材２の各ガイド孔３０xに上下方向スライド移動可能に挿入されるスライドピン３１x（スライド部材３１）と、装置本体１の構成部材１０と中間部材３２間に設けられ、構成部材１０に中間部材３２を装置本体幅方向に対して傾動自在に保持させる保持手段３３などで構成されている。 The holding mechanism 3 is arranged along the width direction of the main body of the device, and is spaced between the intermediate member 32 interposed between the cleaning member 2 and the constituent member 10 of the main body 1 and the width direction of the main body of the cleaning member 2.

As a result, the cleaning member 2 held by the intermediate member 32 so as to be vertically movable can be freely tilted in the width direction of the main body of the apparatus. When the holding means 33 is composed of a rotating disk, for example, the base side of the rotating disk is fixed to the constituent member 10 and the rotating body side is fixed to the intermediate member 32, so that the intermediate member 32 is attached to the constituent member 10. It is held freely by tilting (rotating).

中間部材３２のスライドピン３１xが清掃部材２のガイド孔３０xに沿って上下方向にスライド移動できるとともに、中間部材３２が保持手段３３を介して装置本体１（構成部材１０）に対して傾動（回動）できることにより、清掃部材２は、装置本体１に上下動自在（フリーに上下動可能）に且つ装置本体幅方向に対して傾動自在（フリーに傾動可能）に保持される。
また、上記（ii）の保持機構３のガイド部３０は、ガイド孔３０xに代えてガイド溝で構成することもでき、この場合には、ガイド部３０とスライド部材３１はリニアスライダ形式の機構となるので、シールを施して耐粉塵性を持たせることが望ましい。 The slide pin 31x of the intermediate member 32 can slide and move in the vertical direction along the guide hole 30x of the cleaning member 2, and the intermediate member 32 tilts (turns) with respect to the apparatus main body 1 (constituent member 10) via the holding means 33. By being able to move), the cleaning member 2 is held by the device main body 1 so as to be vertically movable (freely movable up and down) and tiltable in the width direction of the device main body (freely tiltable).
Further, the guide portion 30 of the holding mechanism 3 of the above (ii) can be configured by a guide groove instead of the guide hole 30x. In this case, the guide portion 30 and the slide member 31 are a linear slider type mechanism. Therefore, it is desirable to provide a seal to provide dust resistance.

また、図１９～図２１の実施形態とは逆に、中間部材３２にガイド孔３０x（ガイド部３０）を設け、清掃部材２にスライドピン３１x（スライド部材３１）を設けてもよい。この場合も、清掃部材２は、スライドピン３１xがガイド孔３０xに沿って上下方向にスライド移動できるとともに、中間部材３２が保持手段３３を介して装置本体１（構成部材１０）に対して傾動（回動）できることにより、装置本体１に上下動自在（フリーに上下動可能）に且つ装置本体幅方向に対して傾動自在（フリーに傾動可能）に保持される。 Further, contrary to the embodiment of FIGS. 19 to 21, a guide hole 30x (guide portion 30) may be provided in the intermediate member 32, and a slide pin 31x (slide member 31) may be provided in the cleaning member 2. Also in this case, in the cleaning member 2, the slide pin 31x can slide and move in the vertical direction along the guide hole 30x, and the intermediate member 32 tilts with respect to the device main body 1 (constituent member 10) via the holding means 33 (in this case as well). By being able to rotate), it is held by the device main body 1 so as to be movable up and down (freely up and down) and tiltable in the width direction of the device body (freely tiltable).

I am trying to do it. In FIG. 22, for convenience of explanation, the urging means 4 including the overhanging portions 200 and 320 and the spring mechanism 40 (coil spring) is schematically shown, but the actual urging means 4 is the intermediate member 32. The slide pin 31x is provided in a form that does not prevent the slide pin 31x from engaging (inserting) with the cleaning member 30x.
Since other configurations are the same as those in FIGS. 19 to 21, the same reference numerals are given and detailed description thereof will be omitted.

図２３および図２４は、上記（iii）の保持機構３を有する清掃装置の一実施形態を模式的に示すもので、図２３は側面図、図２４は平面図である。
上記（iii）の保持機構３は、上記（ii）の保持機構３とは逆に、ガイド部３０およびスライド部材３１を構成部材１０と中間部材３２間に、保持手段３３を中間部材３２と清掃部材２間に、それぞれ設けたものである。
この実施形態は、上記（iii）の保持機構３のガイド部３０をガイド孔３０xで、ガイド部３０に係合するスライド部材３１をスライドピン３１xで、それぞれ構成したものである。
装置本体１、清掃部材２および保持機構３の基本構成は、図１～図３と図１１および図１２について説明した通りである。 23 and 24 schematically show an embodiment of the cleaning device having the holding mechanism 3 of (iii) above, FIG. 23 is a side view, and FIG. 24 is a plan view.
In the holding mechanism 3 of the above (iii), contrary to the holding mechanism 3 of the above (ii), the guide portion 30 and the slide member 31 are cleaned between the constituent member 10 and the intermediate member 32, and the holding means 33 is cleaned with the intermediate member 32. It is provided between the members 2 respectively.
In this embodiment, the guide portion 30 of the holding mechanism 3 of the above (iii) is configured by the guide hole 30x, and the slide member 31 that engages with the guide portion 30 is configured by the slide pin 31x.
The basic configurations of the apparatus main body 1, the cleaning member 2, and the holding mechanism 3 are as described with reference to FIGS. 1 to 3 and FIGS. 11 and 12.

装置本体１の前面には、保持機構３を設けるための構成部材１０が、装置本体幅方向に沿って配置され、支持部材１４で装置本体１に支持されている。
保持機構３は、装置本体幅方向に沿って配され、清掃部材２と装置本体１の構成部材１０との間に介在する中間部材３２と、この中間部材３２の装置本体幅方向で間隔をおいた少なくとも２箇所に、上下方向に沿って設けられるガイド孔３０x（ガイド部３０）と、構成部材１０に装置本体幅方向で間隔をおいて設けられ、中間部材３２の各ガイド孔３０xに上下方向スライド移動可能に挿入されるスライドピン３１x（スライド部材３１）と、中間部材３２と清掃部材２間に設けられ、中間部材３２に清掃部材２を装置本体幅方向に対して傾動自在に保持させる保持手段３３などで構成されている。 On the front surface of the apparatus main body 1, a constituent member 10 for providing the holding mechanism 3 is arranged along the width direction of the apparatus main body, and is supported by the apparatus main body 1 by the support member 14.
The holding mechanism 3 is arranged along the width direction of the main body of the device, and is spaced between the intermediate member 32 interposed between the cleaning member 2 and the constituent member 10 of the main body 1 and the intermediate member 32 in the width direction of the main body of the device. Guide holes 30x (guide portions 30) provided along the vertical direction at at least two locations, and guide holes 30x provided in the constituent members 10 at intervals in the width direction of the main body of the apparatus, and vertically in each guide hole 30x of the intermediate member 32. A slide pin 31x (slide member 31) that is slidably inserted, and a holding that is provided between the intermediate member 32 and the cleaning member 2 so that the intermediate member 32 holds the cleaning member 2 tiltably in the width direction of the main body of the device. It is composed of means 33 and the like.

保持手段３３の構成は、図１９～図２１の実施形態に関して説明した通りであり、本実施形態の保持手段３３も、装置本体幅方向中央部に設けられるベアリングで構成されている。すなわち、ベアリングの外輪３３０側が中間部材３２に、内輪３３１側が清掃部材２にそれぞれ固定されることで、中間部材１０に清掃部材２が回動（傾動）自在に保持されている。これにより、清掃部材２が装置本体幅方向に対してフリーに傾動できるようにしている。また、保持手段３３が回転盤で構成される場合には、例えば、回転盤のベース側が中間部材３２に、回転体側が清掃部材２にそれぞれ固定されることで、中間部材３２に清掃部材２が回動（傾動）自在に保持される。 The configuration of the holding means 33 is as described with respect to the embodiments of FIGS. 19 to 21, and the holding means 33 of the present embodiment is also composed of a bearing provided in the central portion in the width direction of the main body of the apparatus.

装置本体１側（構成部材１０）のスライドピン３１xが中間部材３２のガイド孔３０xに沿って上下方向にスライド移動できるとともに、清掃部材２が保持手段３３を介して中間部材３２に対して傾動（回動）できることにより、清掃部材２は、装置本体１に上下動自在（フリーに上下動可能）に且つ装置本体幅方向に対して傾動自在（フリーに傾動可能）に保持される。
また、上記（iii）の保持機構３のガイド部３０は、ガイド孔３０xに代えてガイド溝で構成することもでき、この場合には、ガイド部３０とスライド部材３１はリニアスライダ形式の機構となるので、シールを施して耐粉塵性を持たせることが望ましい。 The slide pin 31x on the device main body 1 side (constituent member 10) can slide up and down along the guide hole 30x of the intermediate member 32, and the cleaning member 2 tilts with respect to the intermediate member 32 via the holding means 33. By being able to rotate), the cleaning member 2 is held by the device main body 1 so as to be vertically movable (freely movable up and down) and tiltable in the width direction of the device main body (freely tiltable).
Further, the guide portion 30 of the holding mechanism 3 of the above (iii) can be configured by a guide groove instead of the guide hole 30x. In this case, the guide portion 30 and the slide member 31 are a linear slider type mechanism. Therefore, it is desirable to provide a seal to provide dust resistance.

本実施形態においても、図２２に示すような付勢手段４を設けることができ、例えば、構成部材１０と中間部材３２に、図２２の実施形態に示すような張り出し部をそれぞれ設け、これらの張り出し部間に付勢手段４を構成するバネ機構（コイルスプリング）を介在させ、このバネ機構により中間部材３２を介して清掃部材２を下方向に付勢するような構成とすることができる。
また、図２３および図２４の実施形態とは逆に、構成部材１０にガイド孔３０x（ガイド部３０）を設け、中間部材３２にスライドピン３１x（スライド部材３１）を設けてもよい。この場合も、中間部材３２側のスライドピン３１xが構成部材１０側のガイド孔３０xに沿って上下方向にスライド移動できるとともに、清掃部材２が保持手段３３を介して中間部材３２に対して傾動（回動）できることにより、清掃部材２は、装置本体１に上下動自在（フリーに上下動可能）に且つ装置本体幅方向に対して傾動自在（フリーに傾動可能）に保持される。 Also in this embodiment, the urging means 4 as shown in FIG. 22 can be provided.

By being able to rotate), the cleaning member 2 is held by the device main body 1 so as to be vertically movable (freely movable up and down) and tiltable in the width direction of the device main body (freely tiltable).

本発明の清掃装置は、遠隔操作により若しくは予め決められたプログラムに従い無人で運転され、路面Ａの清掃を行う。本発明の清掃装置は、堆積物が存在する様々な場所の清掃に用いることができ、また、様々な堆積物を清掃対象とすることができるが、凹凸がある路面を無人で自動清掃できることから、特にコークス炉の炉頂部に堆積した石炭粉を清掃除去するのに適している。すなわち、本発明の清掃装置によれば、路面に１０～２０ｍｍ程度の凹凸があるコークス炉の炉頂部において、路面Ａ（炉頂部）を自由に移動して堆積した石炭粉を確実かつ効率的にかき集め、コークス炉の炉頂部全面を清掃することができる。
本発明の清掃装置によりコークス炉の炉頂部を清掃する場合、コークス炉の炉頂部において装置本体１を走行させて、清掃部材２により所定領域の堆積粉（石炭粉）をかき集めた状態で、装置本体１をそのまま石炭装入孔の近傍まで移動させ、その場所にかき集めた堆積粉を集積させる。このように石炭装入孔の近傍に集められた堆積粉は、適時作業者により石炭装入孔に投入される。 The cleaning device of the present invention is operated unmanned by remote control or according to a predetermined program to clean the road surface A. The cleaning device of the present invention can be used for cleaning various places where deposits are present, and various deposits can be targeted for cleaning, but the uneven road surface can be automatically cleaned unattended. Especially suitable for cleaning and removing coal powder deposited on the top of a coke oven. That is, according to the cleaning device of the present invention, in the top of a coke oven having an unevenness of about 10 to 20 mm on the road surface, the coal powder deposited by freely moving on the road surface A (top) can be reliably and efficiently collected. It can be scraped up and the entire top of the coke oven can be cleaned.
When cleaning the top of a coke oven with the cleaning device of the present invention, the device main body 1 is run on the top of the coke oven, and the cleaning member 2 collects the deposited powder (coal powder) in a predetermined area. The main body 1 is moved as it is to the vicinity of the coal charging hole, and the accumulated dust collected at that place is accumulated. The deposited powder collected in the vicinity of the coal charging hole in this way is thrown into the coal charging hole by a worker in a timely manner.

本発明の清掃装置の清掃能力を評価するため、炉頂部に１０～２０ｍｍの段差があるコークス炉において、以下のような清掃試験を行った。
［試験例１］
本発明装置として、図７（図７～図１０）に示される清掃部材２（ドーザー部材２０）が上下動自在な清掃装置と、図１４（図１４～図１８）に示される清掃部材２（ドーザー部材２０）が上下動自在で且つ装置本体幅方向に傾動自在な清掃装置を用い、従来装置として、固定式の清掃部材（ドーザー部材）を備えた清掃装置を用いた。いずれの装置も、清掃部材（ドーザー部材）は幅が０．５ｍであり、下端部はゴム製のスクレーパで構成した。 In order to evaluate the cleaning ability of the cleaning device of the present invention, the following cleaning test was performed in a coke oven having a step of 10 to 20 mm at the top of the furnace.
[Test Example 1]
As the apparatus of the present invention, a cleaning device in which the cleaning member 2 (dozer member 20) shown in FIGS. 7 (7 to 10) can move up and down, and a cleaning member 2 (FIG. 14 to 18) shown in FIGS. 14 (14 to 18). A cleaning device in which the dozer member 20) can move up and down and tilt in the width direction of the main body of the device is used, and as a conventional device, a cleaning device provided with a fixed cleaning member (dozer member) is used. In each device, the cleaning member (dozer member) had a width of 0.5 m, and the lower end was composed of a rubber scraper.

コークス炉頂部の幅０．５×長さ２ｍの範囲に石炭粉２ｋｇ程度を散布し、その領域の石炭粉を各清掃装置でかき集めて回収し、回収された石炭粉量（回収量）と炉頂部に残留した石炭粉量（残留量）を測定して、（回収量）÷（回収量＋残留量）×１００から回収率を求めた。各清掃装置でそれぞれ３回ずつ清掃試験を行った結果を表１に示す。
表１によれば、従来装置では、清掃部材が路面の段差に倣うことができず、しかも、路面の段差により装置本体が傾き、清掃部材が路面から離れるときに石炭粉を取りこぼすため、回収率は１７～２５％と低い。これに対して、清掃部材２が上下動自在な本発明装置（図７）は、その清掃部材２が路面から離れにくいため、石炭粉の取りこぼしが減り、回収率が６１～６４％に向上している。さらに、清掃部材２が上下動自在で且つ装置本体幅方向に傾動自在な本発明装置（図１４）では、清掃部材２が路面からより離れにくいため、石炭粉の取りこぼしがさらに減り、回収率が７４～８３％に向上している。 About 2 kg of coal powder is sprayed in a range of width 0.5 x length 2 m at the top of the coke oven, and the coal powder in that area is collected by each cleaning device and collected, and the amount of recovered coal powder (recovered amount) and the furnace. The amount of coal powder remaining on the top (residual amount) was measured, and the recovery rate was calculated from (recovery amount) ÷ (recovery amount + residual amount) × 100. Table 1 shows the results of cleaning tests performed three times for each cleaning device.
According to Table 1, in the conventional device, the cleaning member cannot follow the step on the road surface, and the main body of the device is tilted due to the step on the road surface, and coal powder is dropped when the cleaning member separates from the road surface. The rate is as low as 17-25%. On the other hand, in the apparatus of the present invention (FIG. 7) in which the cleaning member 2 can move up and down, since the cleaning member 2 is difficult to separate from the road surface, the amount of coal powder spilled is reduced and the recovery rate is improved to 61 to 64%. ing. Further, in the apparatus of the present invention (FIG. 14) in which the cleaning member 2 can be moved up and down and tilted in the width direction of the main body of the apparatus, the cleaning member 2 is more difficult to separate from the road surface, so that the amount of coal powder dropped is further reduced and the recovery rate is reduced. It has improved to 74-83%.

［試験例２］
図１４（図１４～図１８）に示される清掃部材２（ドーザー部材２０）が上下動自在で且つ装置本体幅方向に傾動自在な本発明装置と、この装置に清掃部材２を下方に付勢する付勢手段４（バネ機構）を付加した本発明装置を用い、［試験例１］と同様の清掃試験を行った。いずれの清掃装置も、清掃部材２（ドーザー部材２０）は幅が０．５ｍであり、下端部はゴム製のスクレーパで構成した。 [Test Example 2]
The device of the present invention in which the cleaning member 2 (dozer member 20) shown in FIGS. 14 (14 to 18) can move up and down and tilt in the width direction of the main body of the device, and the cleaning member 2 is urged downward to this device. The same cleaning test as in [Test Example 1] was performed using the apparatus of the present invention to which the urging means 4 (spring mechanism) was added. In each of the cleaning devices, the cleaning member 2 (dozer member 20) has a width of 0.5 m, and the lower end thereof is composed of a rubber scraper.

付勢手段４（バネ機構）を備えた本発明装置については、付勢手段４による清掃部材２の押し付け力を１ｋｇｆと２ｋｇｆにそれぞれ設定した条件で清掃試験を行った。各清掃装置でそれぞれ３回ずつ清掃試験を行った結果を表２に示す。
表２によれば、付勢手段４（バネ機構）を備えていない本発明装置では回収率が７４～８３％であるのに対し、付勢手段４（バネ機構）を備えた本発明装置では、清掃部材２と路面との密着性が高まるため、押し付け力１ｋｇｆでは回収率が８７～９４％まで向上し、さらに、押し付け力２ｋｇｆでは回収率が９３～９５％まで向上している。 For the apparatus of the present invention provided with the urging means 4 (spring mechanism), a cleaning test was conducted under the condition that the pressing force of the cleaning member 2 by the urging means 4 was set to 1 kgf and 2 kgf, respectively. Table 2 shows the results of cleaning tests performed three times with each cleaning device.
According to Table 2, the recovery rate is 74 to 83% in the apparatus of the present invention not provided with the urging means 4 (spring mechanism), whereas the recovery rate is 74 to 83% in the apparatus of the present invention provided with the urging means 4 (spring mechanism). Since the adhesion between the cleaning member 2 and the road surface is improved, the recovery rate is improved to 87 to 94% when the pressing force is 1 kgf, and further, the recovery rate is improved to 93 to 95% when the pressing force is 2 kgf.
