Description

本考案は、老朽建築物、断熱・耐火材及び焼却炉の解体工事又は微生物濾過フィルター(HEPAフィルター)の交換・解体・撤去工事等に伴い必然的に発生する粉塵(特に、アスベスト粉末、ダイオキシンを含む灰、ウィルス等微生物を含む塵埃等)の固定又は飛散防止を目的とする散水装置を付設又は取外し自在にした解体用重機械(クラッシャ)のノズルアタッチメントに関する。  The present invention provides dust (especially asbestos powder and dioxin) that is inevitably generated during the dismantling of old buildings, heat insulating and refractory materials and incinerators, or the replacement, dismantling and removal of microbial filtration filters (HEPA filters). The present invention relates to a nozzle attachment of a heavy machine for dismantling (crusher) in which a watering device for the purpose of fixing or preventing scattering of dust containing ash, viruses and other microorganisms) is attached or detached.

解体・撤去を必要する老朽建築物は、一般的に住居が密集する都市部に立地していることが多い。そこで、その解体・撤去工事中に発生する粉塵が風に載って広く空間に飛散し、広範囲の周囲住民の健康に悪影響を及ぼす事が無いように、施工前に予め、例えば、被撤去建築物の周りに幕を張って外部空間と遮断し、解体空間を負圧にして、工事中に発生する粉塵が周りに拡散しないようにするとか、工事前に、被解体材を充分に湿らせて粉塵の発生を抑制又は固定するなどの準(予)備工事を施しているのが現状である。  Old buildings that need to be dismantled and removed are often located in urban areas where houses are generally dense. Therefore, in order to prevent dust generated during the dismantling / removal work from spreading on the wind and spreading widely into the space, it will not adversely affect the health of a wide range of surrounding residents, for example, in advance, the building to be removed Put a curtain around the outside space to cut off the dismantling space to prevent the dust generated during construction from diffusing around, or to sufficiently moisten the material to be disassembled before construction. At present, quasi (preliminary) preparatory work such as suppressing or fixing the generation of dust is being carried out.

何れにしても、解体・撤去工事の施工前に、別途に準備措置を施す事を要し、本来の解体作業に加えて、工数が増加せざるを得ない。
又、工事対象物を幕で蔽って外界と遮断するとしても、解体・撤去工事中に発生する粉塵が少なくなる訳では無いから、これに加えて界面活性剤を含む水を散布して被解体材を充分に湿潤させ、工事中に発生する粉塵の抑制又は固定をしなければならない。液の散布・噴霧の準備作業の進捗状況、時期又は時間に応じて解体・撤去の日程が制約される。
In any case, it is necessary to take separate preparatory measures before the dismantling / removal work. In addition to the original dismantling work, the number of man-hours must be increased.
Also, even if the work object is covered with a curtain and shut off from the outside world, the dust generated during the dismantling / removal work will not be reduced. The dismantling material must be sufficiently moistened to prevent or fix dust generated during construction. The schedule of dismantling / removal is restricted according to the progress, timing or time of preparation work for spraying / spraying liquid.

にも拘らず、従来の解体用重機には、その種目的の工事を施す装備が準備されていなかった。
この改善策としては、解体用機械(重機)に液の噴霧装置を(公知の機構を利用して)付設し、又は、取り外すようにし、公知の解体用機械を利用し作業に先だって又は解体作業中に工事現場又は被解体材を湿潤させて、発生する粉塵の抑制及び固定を行うようにするものである。本考案によれば、既知の解体用機械を簡単な手当により噴霧作業に仕向け、又、噴霧装置の作業領域が常にクラッシヤの作業部を包括しているので、撤去作業前又は直前に目的の被解体材を充分湿潤させて、作業時の粉塵の発生を抑制又は固定することが可能である。解体・撤去作業中に発生する粉塵そのものを湿潤させてその拡散を抑制する事も可能である。
Nonetheless, conventional heavy equipment for dismantling has not been equipped with equipment for that kind of construction.
As an improvement measure, attach or remove a liquid spraying device (using a known mechanism) to a dismantling machine (heavy equipment), or use a known dismantling machine or perform dismantling work. The construction site or the material to be disassembled is moistened to suppress and fix the generated dust. According to the present invention, a known dismantling machine is directed to a spraying operation with a simple allowance, and the work area of the spraying device always includes the working part of the crasher. It is possible to sufficiently moisten the dismantling material to suppress or fix the generation of dust during operation. It is also possible to suppress the diffusion by moistening the dust itself generated during dismantling and removal.

被解体物の構造によっては、施工以前の水を散布・噴霧が充分に届かない個所があって、作業中発生する粉塵を抑制する事が出来ない場合も生じるが、本考案によれば、クラッシャ部に対して水の散布・噴霧が不完全であることは生じない。更に、作業中に、粉塵の発生状態を観察しながら、必要に応じて適切な液の散布・噴霧を行うことが可能である。

Depending on the structure of the object to be disassembled, there may be places where the pre-construction water is not sufficiently sprayed and sprayed, and it may not be possible to suppress dust generated during the work. Incomplete spraying / spraying of water on the part does not occur. Furthermore, it is possible to spray and spray an appropriate liquid as necessary while observing the state of dust generation during the operation.

解決しようとする問題点は、解体作業の施工に先だって、既知の解体用重機を噴霧作業向けに仕向けること、解体・撤去作業とは別個に作業領域の被解体物に液の散布・噴霧を施す為の予備工事を省略すること、常に解体・撤去部の直上位置から適確に液の散布・噴霧を施す事を可能にすること、粉塵の発生を目視・確認しながら、時間を置かずに液の散布・噴霧量、時期・時間を調節できること、にある。  The problem to be solved is that prior to the dismantling work, a known heavy machine for dismantling is directed to the spraying work, and the dismantling / spraying work is sprayed / sprayed on the work to be dismantled separately from the dismantling / removal work. Without any preparatory work, always allowing the liquid to be properly sprayed and sprayed from the position directly above the dismantling / removal part, and checking the occurrence of dust without taking time. It is to be able to adjust the spraying / spraying amount, timing and time of liquid.

本考案は、(1)解体用重機のアームの端部に取り付けたクラッシャの上部空間に伸出する一対のアームの上端部を結んで、下周面に噴霧ノズルを取り付けた回転軸の両軸端を軸受すると共に、前記回転軸に中心線を通して重錘を垂下・固定して、その重錘に基づいて前記回転軸の中心軸の周りの回転角度を制御し、前記アームの取り付け角度を変え、同時に伸出アームの角度が変動した時も、前記回転軸の軸線周りの位置が常に一定になるようにし、以って前記噴霧ノズルの噴射方向を一定に保持し、噴霧ノズルにポンプを介して水又は薬液を送給するようにして、前記アームの取付け角度の変化に関係無く、前記噴霧ノズルの噴霧散布範囲が、前記クラッシャの作業範囲を常時、カバーできるものとする解体用重機のノズルアタッチメント。  The present invention is (1) both shafts of a rotating shaft having a spray nozzle attached to the lower peripheral surface, connecting the upper ends of a pair of arms extending to the upper space of a crusher attached to the end of a heavy machine for dismantling. Bearing the end and hanging and fixing a weight through the center line to the rotating shaft, and controlling the rotation angle around the center axis of the rotating shaft based on the weight, and changing the mounting angle of the arm At the same time, even when the angle of the extension arm fluctuates, the position around the axis of the rotating shaft is always kept constant, so that the spraying direction of the spray nozzle is kept constant, and the spray nozzle is connected via a pump. Nozzle of heavy machinery for dismantling, which can supply water or chemical solution, so that the spraying range of the spray nozzle can always cover the working range of the crusher regardless of the change in the mounting angle of the arm. Attachment men .

(2)一対の伸出アームの基端部とアームの先端部との間を回転軸を介して着脱可能に連結すると共に、前記伸出アームの基端ボス部外周に中心線を通して重錘を垂下・固定し、その重錘を利用して前記ボス部の回転軸の軸線周りの位置を制御し、以って前記アームの取り付け角度を変えた時も、前記伸出アームの角度位置が変化しないようにし、前記アームの取付け角度の変動に関係無く、当該噴霧ノズルの液の散布範囲が、常に前記クラッシャ作業部範囲をカバーする上記第(1)項記載の解体用重機のノズルアタッチメントを特徴とする。(2) A base end portion of the pair of extending arms and a tip end portion of the arm are detachably connected via a rotating shaft, and a weight is passed through a center line to the outer periphery of the base end boss portion of the extending arm. The position of the extension arm changes even when the arm is mounted and the position of the arm is changed by controlling the position around the axis of the rotation axis of the boss using the weight. The disassembling heavy equipment nozzle attachment according to (1) above, wherein the spraying liquid range of the spray nozzle always covers the crusher working part range regardless of fluctuations in the mounting angle of the arm. And

本考案のノズルアタッチメントは、既知の解体用重機に対し簡単な手続きにより付属させて、噴霧工事に仕向ける事ができ、又、不必要な場合は取り外すことが可能である。
伸出アームの先端部に取り付けた噴霧ノズルの噴霧領域が常にクラッシャ部をカバーしているので、作業前に湿潤手当が可能でなかった被解体物の如何なる場所でも、充分に湿潤することができ、更に、解体時に新たに見付かった未噴霧の個所についても、解体作業の進行に伴って適切に湿潤することが出来、粉塵の発生量が抑制される。
The nozzle attachment of the present invention can be attached to a known demolition heavy machine by a simple procedure, can be used for spraying work, and can be removed if unnecessary.
Since the spray area of the spray nozzle attached to the tip of the extension arm always covers the crusher section, it can be sufficiently moistened at any place of the object to be disassembled where wet allowance was not possible before work. Furthermore, unsprayed parts newly found at the time of dismantling can also be appropriately wetted as the dismantling operation proceeds, and the amount of dust generated is suppressed.

解体施工に当たって、予め、湿潤の準備工程を組む必要が無いし、解体工事の日程を。準備工程実施のために、制約されることが少ない。  There is no need to set up a pre-wetting process in advance for dismantling work, and schedule the dismantling work. There are few restrictions due to the preparation process.

如何なる既知の解体用重機にも着脱可能であって、噴霧作業に仕向けることが可能であること。
アームが如何なる角度を採っても、伸出アーム先端に取り付けた噴霧ノズルの噴射領域の中心線は、常にクラッシャ作業部に向いて揺動して、前記粉塵発生個所をカバーしていること。
It can be attached to and detached from any known demolition heavy equipment and can be used for spraying work.
Regardless of the angle of the arm, the center line of the spray area of the spray nozzle attached to the tip of the extension arm always swings toward the crusher working part to cover the dust generation part.

図1は、本考案装置の一実施例の全体側面図を示し、例えば、解体用重機の前面に取り付けたクラッシャアーム1の先端部に一対のクラッシャ爪2を軸止し、前記クラッシャ爪に油圧装置を連動させ、爪の口部3を開閉して被撤去物を摘み、かつ、移動させて解体するように構成したものにおいて、被解体物の構造に応じ、クラッシャアーム1の取付け角度を変動させ、前記クラッシャ爪2の口部3を上下させて被撤去物件に近接するように移動させ、前記爪の口部3を開閉して被解体物を摘み移動させて、解体作業を実施する解体用重機の一例である。  FIG. 1 shows an overall side view of an embodiment of the device according to the present invention. For example, a pair of crusher claws 2 are fixed to the tip of a crusher arm 1 attached to the front surface of a heavy machine for dismantling, and hydraulic pressure is applied to the crusher claws. Interlocking the device, opening and closing the claw mouth 3 to pick up the object to be removed, and moving it to disassemble it. The mounting angle of the crusher arm 1 varies depending on the structure of the object to be disassembled. The clawer claw 2 has its mouth 3 moved up and down to move closer to the object to be removed, and the claw mouth 3 is opened and closed to pick up and move the object to be dismantled. It is an example of heavy machinery.

前記解体用重機のクラッシャアーム1の先端部には、前記クラッシャ爪2とは別に噴霧ユニットが取り付けてある。此の噴霧ユニットの伸出アーム9基部は、例えば、クラッシャアーム1の先端部を縦貫する軸12の両端部に嵌着したボス13に固着されており、相互回転しないよう両アーム間にはストッパーを設けて、クラッシャアーム1の先端部に取り付け、又は取り外す事が可能である。A spray unit 4 is attached to the tip of the crusher arm 1 of the demolition heavy machine separately from the crusher claw 2. The extension arm 9 base portion of the spray unit 4 is fixed to, for example, bosses 13 fitted to both end portions of the shaft 12 passing through the tip end portion of the crusher arm 1, so that the two arms do not rotate with each other. A stopper can be provided and attached to or removed from the tip of the crusher arm 1.

又、伸出アーム9の先端部には、両端を回転自在に軸受けされ、クラッシャ2側の周面の軸方向に連設した噴霧ノズル8を備えた回転シャフト(ノズル取付け軸)10が設けてあり、その中心軸線を通してし重錘11を垂下・固着し、この重錘11の重さを利用して、ノズル取付け軸10の中心軸線周りの揺動を制御し、一対の伸出(ノズル)アーム9の取付け角度θが変動した時にも、ノズル取付け軸10に設けた噴霧ノズル8の噴霧方向軸が変動しない機構を形成する。  Further, a rotary shaft (nozzle mounting shaft) 10 provided with a spray nozzle 8 that is rotatably supported at both ends and continuously provided in the axial direction of the peripheral surface on the crusher 2 side is provided at the distal end portion of the extending arm 9. Yes, the weight 11 is suspended and fixed through the center axis, and the swing of the nozzle mounting shaft 10 around the center axis is controlled by using the weight of the weight 11, and a pair of extensions (nozzles) Even when the mounting angle θ of the arm 9 varies, a mechanism is formed in which the spray direction axis of the spray nozzle 8 provided on the nozzle mounting shaft 10 does not vary.

噴霧ノズル8は、解体用重機に付設した水又は薬液タンク5に取り付けたポンプ6に連結するホース7に連通し、予めクラッシャ爪2の口部3、即ち、直接に被解体物件付近及び撤去作業の現場を湿潤して、解体作業中、被解体物から必然的に発生する粉塵、塵埃の飛散を抑制又は防止する。
従って、水又は薬液の噴霧時期、時間、噴霧量は、重機の操縦者が解体作業の実情に応じて制御する事ができるものとされている。
The spray nozzle 8 communicates with a hose 7 connected to a pump 6 attached to a water or chemical tank 5 attached to a demolition heavy machine. In order to suppress or prevent the scattering of dust and dust inevitably generated from the object to be disassembled during the dismantling operation.
Therefore, the spray timing, time, and spray amount of water or chemicals can be controlled by the heavy equipment operator in accordance with the actual situation of the dismantling work.

上記のように、噴霧ユニットはノズル(伸出)アーム9の先端部に両端を回転自在に軸受け(要すれば、防塵ボール軸受、ローラ軸受を施す)され、クラッシャ爪2に向いた周面に、軸方向に複数個設けた噴霧ノズル8を備えた回転シャフト(ノズル取付け軸)10と、その中心軸線を通してし重錘11を垂下・固着し、その重錘11の重さを利用して、ノズル取付け軸10の中心軸線周りの揺動を制御し、一対のノズルアーム9の取付け角度θが変動した時にも、ノズル取付け軸10に設けた噴霧ノズル8の噴霧方向軸が変動しない機構とより形成される。
そして何れの噴霧ノズル8は、連結するホース7から水又は薬液を供給されて噴霧・制御され、クラッシャ爪2の口部3付近を湿潤する。
As described above, the spray unit 4 is rotatably supported at the tip of the nozzle (extension) arm 9 at both ends (if necessary, a dustproof ball bearing and a roller bearing are provided), and the peripheral surface facing the crusher claw 2 Further, a rotating shaft (nozzle mounting shaft) 10 provided with a plurality of spray nozzles 8 provided in the axial direction and a weight 11 are suspended and fixed through the central axis, and the weight of the weight 11 is used. And a mechanism that controls the swing of the nozzle mounting shaft 10 around the central axis so that the spray direction axis of the spray nozzle 8 provided on the nozzle mounting shaft 10 does not vary even when the mounting angle θ of the pair of nozzle arms 9 varies. Is formed.
Each of the spray nozzles 8 is supplied with water or a chemical solution from the hose 7 to be connected and sprayed and controlled to wet the vicinity of the mouth 3 of the crusher claw 2.

図2及び図3は、前記噴霧ユニットの一部詳細側面図及び正面図を示し、前述のような機構を採用する事によって、工事中、クラッシャアーム1の取付け角度を変え(その時は自動的に一対のノズルアーム9の取付け角度θが変動する)、クラッシャ爪2の位置を上下して、作業口3部を被解体物件に近付くよう又は撤去するように操作した結果、一対のノズルアーム9の取付け角度θが変動した時にも、重錘が噴霧ノズル取付け軸10の軸周りの揺動を制御し、その結果、噴霧ノズル8の噴霧方向が変動せず、常にクラッシャ作業部を指向し、その噴霧領域が作業部をカバーしている為、効果的に粉塵の発生を抑制する事ができる。2 and 3 show a partial side view and a front view of a part of the spray unit 4. By adopting the mechanism as described above, the mounting angle of the crusher arm 1 is changed during construction (at that time, automatic The mounting angle θ of the pair of nozzle arms 9 varies), and the position of the claw claw 2 is moved up and down so that the working port 3 is moved closer to or removed from the object to be disassembled. The weight controls the swinging around the spray nozzle mounting shaft 10 even when the mounting angle θ of the spray nozzle fluctuates. As a result, the spraying direction of the spray nozzle 8 does not fluctuate and always points to the crusher working part, Since the spray area covers the working part, generation of dust can be effectively suppressed.

同じく、図2及び図3は、前記噴霧ユニットの実施例2の詳細側面図及び正面図を示すもので、図中、実施例1において解説した機構(符号、作用を含めて)は、実施例2でも、その侭、採用している。
図中、クラッシャアーム1の先端部と一対のノズルアーム9の基端ボス部13とは、回転自在なシャフト12を介して連結され、かつ、ノズルアーム9の基端ボス部の外周に中心軸線を通し、重錘14を垂下・固着して、その重錘14の重さを利用する事により、ボス13、即ち一対のノズルアーム9のシャフト12周りの揺動を制御し、以ってクラッシャアーム1の取付け角度(図2において)が変動した時でも、一対のノズルアーム9の取付け角度θ、即ち、噴霧ノズル取付け軸10の回動位置が変動しないように構成する。
Similarly, FIGS. 2 and 3 show a detailed side view and a front view of the spraying unit 4 according to the second embodiment. In the figure, the mechanism described in the first embodiment (including symbols and actions) is implemented. In Example 2, that trap is adopted.
In the drawing, the tip end portion of the crusher arm 1 and the base end boss portion 13 of the pair of nozzle arms 9 are connected via a rotatable shaft 12, and a central axis line is provided on the outer periphery of the base end boss portion of the nozzle arm 9. The weight 14 is suspended and fixed, and the weight of the weight 14 is used to control the swing of the boss 13, that is, the pair of nozzle arms 9 around the shaft 12. Even when the mounting angle of the arm 1 (in FIG. 2) fluctuates, the mounting angle θ of the pair of nozzle arms 9, that is, the rotational position of the spray nozzle mounting shaft 10 does not vary.

工事中、クラッシャアーム1の先端部を上下に移動させ、噴霧ノズル取付け軸10が、被解体材に当たったときには、ノズルアーム9は回転シャフト12を軸として回動して退避するし、又、元に復したときは、重錘14の復元装置を利用して、旧角度を保つ。
何れの場合にも、噴霧ノズルの噴射方向は変動することが無い。
During construction, when the tip of the crusher arm 1 is moved up and down and the spray nozzle mounting shaft 10 hits the material to be disassembled, the nozzle arm 9 rotates around the rotary shaft 12 and retracts. When restored, the old angle is maintained using the restoring device of the weight 14.
In any case, the spray direction of the spray nozzle does not change.

上記実施例では、本考案の噴霧ユニットは、クラッシャ用重機に付設した場合について、説明したが、その主要構造を変えること無く、バイブロ破砕機にも施すことが可能で、その際の作用、効果も、先の説明から、大きく逸脱するするものではない。
尚、取付け、取外し構造は、既知の機構を採用する。先のクラッシャアーム1の先端部を縦貫する軸12及びボス部もその一例を示す。
In the above embodiment, the spray unit 4 of the present invention has been described for the case where it is attached to a crusher heavy machine, but it can be applied to a Vibro crusher without changing its main structure. The effect does not deviate significantly from the above description.
In addition, a known mechanism is adopted for the attachment / detachment structure. An example is also shown of the shaft 12 and the boss that run through the tip of the previous crusher arm 1.

本考案装置を解体用重機に付設又は取り外すことによって、従来、噴霧装置を準備してない解体用重機も簡単に噴霧作業に振り向けることが可能であり、従来、噴霧工事を予備又は付帯作業として、本体工事から分離されていたものを合わせて実施可能とした点において、解体手順を円滑に進めることができ、又、解体・撤去工事中でも、充分でなかった湿潤手当を補償して、場所、時間を問わず実施が出来ることにおいて、経済的メリットが在るものと信じられる。  By attaching or detaching the device of the present invention to or from a heavy machine for dismantling, it is possible to easily turn a heavy machine for dismantling that has not been provided with a spraying device into a spraying work. In terms of making it possible to implement things that were separated from the main work, the dismantling procedure can proceed smoothly, and even during the dismantling and removal work, the wet allowance that was not sufficient was compensated for, It is believed that there is an economic merit in being able to implement any time.
