Description

本発明は、散水装置及びこれを備えた解体重機に係り、より詳細には、重機アタッチメントの刃部を効率よく冷却することができる散水装置及びこれを備えた解体重機に関する。   The present invention relates to a sprinkler and a weight dispenser provided with the same, and more particularly, to a water sprinkler capable of efficiently cooling a blade portion of a heavy equipment attachment and a weight dispenser having the same.

特許文献１には、散水機能を有する解体重機が示される。これによれば、解体重機のアームの先端部に散水ノズルが設けられ、散水ノズルから破砕箇所周辺に散水を行なう。人手による散水に比較して、効果のある粉塵の防止が行なえるとしている。しかしながら、重機に取り付けられるアタッチメントには散水を行なっていない。超大型重機のブームに装着されるアタッチメントには、鉄骨カッターや大割ニブラなどがある。鉄骨カッターは、例えば板厚２０ｍｍのＨ鋼を切断でき、大割ニブラは高強度コンクリートを圧砕できる。そのためアタッチメントの刃部が高温になって、解体部材に発火する危険もある。   Patent Literature 1 discloses a weight release machine having a watering function. According to this, a watering nozzle is provided at the tip of the arm of the weight-separating machine, and watering is performed from the watering nozzle to the vicinity of the crushed portion. It is said that dust can be effectively prevented compared to manual watering. However, attachments attached to heavy equipment are not watered. Attachments attached to the boom of heavy-duty heavy equipment include steel cutters and large nibbles. The steel cutter can cut H steel having a thickness of 20 mm, for example, and the large nibble can crush high-strength concrete. Therefore, there is a danger that the blade portion of the attachment becomes hot and the disassembly member is ignited.

鉄骨カッターは、一例として重量が約１９０００ｋｇ（＝１９トン）、高さが５．４ｍ、幅が３ｍ、刃部の切断力は６０００ｋＮ／ｍ２である。大割ニブラは、一例として重量が約１８０００ｋｇ（１８トン）、高さが４．８ｍ、幅が４．２ｍ、刃部の圧砕力は６７００ｋＮ／ｍ２である。このため、Ｈ鋼の切断時や、コンクリートの圧砕時には、刃部が熱を持つ。火力発電所の解体においては、石炭屑、配管用のゴムシール材、オイルなど燃えやすい材料が多いので、より安全な解体が求められている。 As an example, the steel cutter has a weight of about 19000 kg (= 19 tons), a height of 5.4 m, a width of 3 m, and a cutting force of a blade portion of 6000 kN / m 2 . As an example, the large nibble has a weight of about 18000 kg (18 tons), a height of 4.8 m, a width of 4.2 m, and a crushing force of a blade portion of 6700 kN / m 2 . For this reason, when cutting H steel or crushing concrete, the blade portion has heat. In the dismantling of thermal power plants, there are many flammable materials such as coal debris, rubber seals for pipes, and oil, so safer dismantling is required.

特開平９−１２５７０９号公報JP-A-9-125709

本発明の目的は、重機アタッチメントの刃部を効率よく冷却できる散水装置及びこれを備えた解体重機を提供することにある。   An object of the present invention is to provide a sprinkler capable of efficiently cooling a blade portion of a heavy equipment attachment, and a weight release machine having the same.

本発明による散水装置は、重機アタッチメントの上部に取り付けられる環状パイプと、前記環状パイプに設けられ、圧力水が送り込まれる水供給口と、前記環状パイプに設けられ、内部が水滴で充たされた円錐体の形状に散水する複数の散水ノズルと、が備えられ、散水が、重機アタッチメントの刃部に向かって行われ、刃部先端面の平面視で、前記円錐体の底部の半径が、前記環状パイプの半径より大きいことを特徴とする。   The water sprinkling device according to the present invention has an annular pipe attached to the upper part of the heavy equipment attachment, a water supply port provided in the annular pipe, and pressure water supplied thereto, and provided in the annular pipe, and the inside is filled with water droplets. A plurality of watering nozzles for watering in the shape of a cone, and watering is performed toward the blade portion of the heavy equipment attachment, and in plan view of the blade tip surface, the radius of the bottom of the cone is It is characterized by being larger than the radius of the annular pipe.

前記散水ノズルは、１流体ノズルと、２流体ノズルと、が交換可能に装着され、前記２流体ノズルでは空気と圧力水が混合されて噴射されることを特徴とする。   The water spray nozzle is characterized in that a one-fluid nozzle and a two-fluid nozzle are interchangeably mounted, and the two-fluid nozzle is configured to mix and eject air and pressurized water.

前記圧力水に、界面活性剤が添加されることを特徴とする。   A surfactant is added to the pressurized water.

前記散水ノズルに換えて、封止キャップが設けられることを特徴とする。   A sealing cap is provided in place of the watering nozzle.

本発明による解体重機は、前記散水装置が搭載された解体重機であって、運転室の操作盤に、前記散水装置の散水の開始と停止の操作ボタンが設けられることを特徴とする。   According to another aspect of the present invention, there is provided a weighing machine equipped with the watering device, wherein operation buttons for starting and stopping watering of the watering device are provided on an operation panel of a cab.

本発明による散水装置によれば、
（１）重機アタッチメントの上部に環状パイプを設け、環状パイプに設けた複数の散水ノズルから、刃部に向かって散水したので、刃部を効率よく冷却できる。
（２）刃部先端面の平面視で、円錐体の底部の半径を環状パイプの半径より大きくしたので、刃部が回動しても、刃部は複数の円錐体によって形成される散水空間内にあるので、刃部の正面、背面及び側面を効率よく冷却できる。
（３）重機アタッチメントの下部の刃部に向かって散水するので、刃部の前方の解体物にも散水でき、粉塵の飛散防止ができる。
（４）煙が出ているような箇所に向けて散水すれば、消火と発火抑制ができる。 According to the watering device according to the present invention,
(1) An annular pipe is provided above the heavy equipment attachment, and water is sprayed toward the blade from a plurality of water spray nozzles provided on the annular pipe, so that the blade can be efficiently cooled.
(2) Since the radius of the bottom of the cone is larger than the radius of the annular pipe in a plan view of the tip end surface of the blade, the blade is formed by a plurality of cones even when the blade rotates. , The front, back and side surfaces of the blade can be efficiently cooled.
(3) Since water is sprayed toward the lower blade portion of the heavy equipment attachment, water can also be sprayed on the dismantled object in front of the blade portion, and scattering of dust can be prevented.
(4) If water is sprayed toward places where smoke is emitted, fire extinguishing and fire suppression can be achieved.

１流体ノズルと２流体ノズルが交換可能に装着できるので、例として、２流体ノズルを装着すれば、空気と水が混合されて噴射され霧が発生するので、水を大幅に節約できる。   Since the one-fluid nozzle and the two-fluid nozzle can be interchangeably mounted, for example, if a two-fluid nozzle is mounted, air and water are mixed and jetted to generate a mist, so that water can be largely saved.

圧力水に界面活性剤を添加し、水の表面張力を低下させたので、水が解体物の細部まで浸透する。水の浸透性が向上するので、例えばアスベスト粉塵の飛散防止に効果がある。   The addition of a surfactant to the pressurized water reduced the surface tension of the water, so that the water penetrated into the details of the demolition. Since the permeability of water is improved, it is effective in, for example, preventing scattering of asbestos dust.

散水ノズルに封止キャップを取付け可能としたので、使用する散水ノズルの数を制限できる。例えば８つの散水ノズルのうち、４つのみを使用する事ができる。解体する素材によって、散水の量を制限する場合に有効である。   Since the sealing cap can be attached to the watering nozzle, the number of watering nozzles to be used can be limited. For example, out of eight watering nozzles, only four can be used. This is effective when restricting the amount of watering depending on the material to be dismantled.

本発明による解体重機によれば、
（１）重機アタッチメントの上部に環状パイプを設け、環状パイプの散水ノズルから散水したので、重機アタッチメントの刃部を効率よく冷却できる。（２）刃部先端面の平面視で、円錐体の底部の半径を環状パイプの半径より大きくしたので、刃部が回動しても、刃部の正面、背面及び側面を冷却できる。（３）重機アタッチメントの下部の刃部に向かって散水するので、刃部の前方の解体物にも散水でき、解体物の粉塵の飛散が防止できる。（４）煙が出ているような箇所に向けて散水すれば、消火と発火抑制ができる。燃えやすい材料が多い場所に使用する解体重機として好適である。（５）運転室の操作盤に、散水装置の散水の開始と停止の操作ボタンを設けたので、散水の開始と停止が運転席から操作できる。 According to the weight release machine according to the present invention,
(1) Since the annular pipe is provided above the heavy equipment attachment and water is sprayed from the watering nozzle of the annular pipe, the blade part of the heavy equipment attachment can be efficiently cooled. (2) Since the radius of the bottom of the cone is larger than the radius of the annular pipe in plan view of the blade tip end surface, the front, back and side surfaces of the blade can be cooled even if the blade rotates. (3) Since water is sprayed toward the lower blade portion of the heavy equipment attachment, water can also be sprayed on a dismantled object in front of the blade portion, and scattering of dust of the dismantled object can be prevented. (4) If water is sprayed toward places where smoke is emitted, fire extinguishing and fire suppression can be achieved. It is suitable as a weighing machine used in places where there are many flammable materials. (5) Since the operation panel of the operator cab is provided with operation buttons for starting and stopping watering of the watering device, starting and stopping of watering can be operated from the driver's seat.

以下、添付の図面を参照して、本発明による散水装置及びこれを備えたを解体重機を詳細に説明する。   Hereinafter, a sprinkler according to the present invention and a weighing machine having the same will be described in detail with reference to the accompanying drawings.

図１は、本発明による散水装置１０の斜視図である。散水装置１０は、環状パイプ１と複数の散水ノズル３とからなる。環状パイプ１には、圧縮水が供給される水供給口５が設けられる。環状パイプ１は、重機アタッチメント５の上部に取り付けられるので、溶接で環状パイプ１に接合した複数の取付ブラケット７を有する。散水ノズル３は、図１に示すように、１流体ノズル３ａや２流体ノズル３ｂが交換可能に装着される。２流体ノズル３ｂは、水と空気を混合して霧を噴射できる。散水ノズルを使用しない場合には、散水ノズル３に換えて、封止キャップ４が装着される。散水ノズル３は、環状パイプ１の下側に突出するノズル取付部１ａにネジ着される。本実施例では、ノズル取付部１ａは円周上に等間隔で８つを実装した。２つのノズル取付部１ａのなす角度は４５度となる。環状パイプ１の半径は、ｒ１で示す。半径ｒ１は、これに限るものではないが、約７０ｃｍである。   FIG. 1 is a perspective view of a watering device 10 according to the present invention. The watering device 10 includes an annular pipe 1 and a plurality of watering nozzles 3. The annular pipe 1 is provided with a water supply port 5 to which compressed water is supplied. Since the annular pipe 1 is attached to the upper part of the heavy equipment attachment 5, it has a plurality of mounting brackets 7 joined to the annular pipe 1 by welding. As shown in FIG. 1, the watering nozzle 3 is provided with a one-fluid nozzle 3a or a two-fluid nozzle 3b so as to be exchangeable. The two-fluid nozzle 3b can mix water and air to spray mist. When the watering nozzle is not used, a sealing cap 4 is attached instead of the watering nozzle 3. The sprinkling nozzle 3 is screwed to a nozzle mounting portion 1a protruding below the annular pipe 1. In this embodiment, eight nozzle mounting portions 1a are mounted on the circumference at equal intervals. The angle between the two nozzle mounting portions 1a is 45 degrees. The radius of the annular pipe 1 is indicated by r1. The radius r1 is, but not limited to, about 70 cm.

図２は、装着状態にある散水装置１０の平面図である。本実施例では、重機アタッチメント５０は、具体的には鉄骨カッター６０である。散水装置１０は、重機アタッチメント５０の上部に取り付ける。取付ブラケット７は、重機アタッチメント５０の上部から外側に突出するように取り付ける。散水装置１０が重機アタッチメント５０に装着されている場合、単体の重機アタッチメント５０を横に寝かして置くと、環状パイプ１に荷重がかかる。その場合は重機アタッチメント５０を立て掛けるスタンドを使用する。これに限らず、散水装置１０を着脱可能に取り付けるとしてもよい。そうすれば、単体の重機アタッチメント５０の寝かし置きができる。   FIG. 2 is a plan view of the watering device 10 in a mounted state. In the present embodiment, the heavy equipment attachment 50 is specifically a steel frame cutter 60. The watering device 10 is attached to the upper part of the heavy equipment attachment 50. The mounting bracket 7 is mounted so as to protrude outward from the upper part of the heavy equipment attachment 50. When the sprinkler device 10 is mounted on the heavy equipment attachment 50 and the single heavy equipment attachment 50 is laid on its side, a load is applied to the annular pipe 1. In that case, a stand for leaning the heavy equipment attachment 50 is used. The invention is not limited to this, and the watering device 10 may be detachably attached. Then, the single heavy equipment attachment 50 can be set aside.

図３は、装着状態にある散水装置１０の正面図である。重機アタッチメント５０は、上部５０ａと下部５０ｂからなる。上部５０ａが重機のブームの先端に取り付けられる。下部５０ｂには刃部９が設けられ、下部５０ｂは、内部に備えた回動機構により、縦軸を中心に回動できる。図３は、刃部９が正面を向いており、幅が広い状態にある。散水は、左右の散水ノズル３からの散水を示す。散水は、円錐体の形状で、内部が水滴で充たされる。図３によれば、円錐体は、刃部の先端だけではなく、刃部９の全体を覆う大きさとする。本実施の重機アタッチメント５０は、鉄骨カッター６０であり、刃部９の長さは約１．２ｍである。   FIG. 3 is a front view of the watering device 10 in a mounted state. The heavy equipment attachment 50 includes an upper part 50a and a lower part 50b. The upper part 50a is attached to the tip of the boom of the heavy equipment. The lower portion 50b is provided with a blade portion 9, and the lower portion 50b can be turned around a vertical axis by a turning mechanism provided inside. FIG. 3 shows a state in which the blade portion 9 faces the front and is wide. Watering indicates watering from the left and right watering nozzles 3. The watering is in the form of a cone, the interior of which is filled with water droplets. According to FIG. 3, the cone is sized to cover not only the tip of the blade but also the entire blade 9. The heavy equipment attachment 50 of the present embodiment is a steel frame cutter 60, and the length of the blade portion 9 is about 1.2 m.

図４は、装着状態にある散水装置１０の右側面図である。刃部９は板状のもので、右側面図での幅は正面での幅より小さい。円錐体の形状に散水するので、刃部９の正面と背面に水滴がぶつかり、効率よく冷却を行える。刃部先端面での円錐体８の底面の半径をｒ２で示す。   FIG. 4 is a right side view of the watering device 10 in a mounted state. The blade 9 has a plate shape, and the width in the right side view is smaller than the width in the front. Since water is sprayed in the shape of a cone, water droplets collide with the front and back surfaces of the blade portion 9 and cooling can be performed efficiently. The radius of the bottom surface of the cone 8 at the tip end surface of the blade is indicated by r2.

図５は、刃部先端面での各散水ノズル３の散水範囲を示す平面図である。散水ノズル３の位置は、丸囲み数字１〜８で示す。点線で示す円Ｃ１〜Ｃ８は、刃部先端面での散水の円錐体８の底面を示す。円Ｃ１〜Ｃ８は、半径がｒ２とする。半径ｒ２は、環状パイプ１の半径ｒ１より大きい。そのため環状パイプ１の中心では、円Ｃ１〜Ｃ８の８つの円が重なる領域となる。この部分では散水が重畳される。円Ｃ１〜Ｃ８が重畳しない領域や、２〜７つの円が重畳される領域などができる。円Ｃ１〜Ｃ８の半径が小さく散水の形状が略円柱体の場合、刃部９には水滴がぶつからない。   FIG. 5 is a plan view showing a watering range of each watering nozzle 3 on the blade tip surface. The position of the watering nozzle 3 is indicated by circled numbers 1 to 8. Circles C1 to C8 indicated by dotted lines indicate the bottom surface of the watering cone 8 at the tip end surface of the blade portion. The circles C1 to C8 have a radius of r2. The radius r2 is larger than the radius r1 of the annular pipe 1. Therefore, at the center of the annular pipe 1, an area where eight circles C1 to C8 overlap is formed. Sprinkling is superimposed on this part. An area where the circles C1 to C8 do not overlap, an area where two to seven circles overlap, and the like are created. When the radius of the circles C1 to C8 is small and the shape of the water spray is a substantially cylindrical body, water drops do not hit the blade portion 9.

図６は、散水装置１０を装着した解体重機１００の正面図である。重機アタッチメント５０は、図６では左下方向を向いているが、水平にしたり、左斜め上方向にしたりできる。どの方向に向けても、散水は刃部９に向かって行なうことができる。解体重機１００の運転室１１の操作盤には、操作ボタン（図示せず）が設けられ、散水の開始と停止を散水装置１０に指示できる。同様に２流体ノズル３ｂへの圧縮空気の送り込み開始と停止も指示できる。   FIG. 6 is a front view of the weight release machine 100 to which the watering device 10 is attached. Although the heavy equipment attachment 50 faces the lower left direction in FIG. 6, the attachment 50 can be horizontal or diagonally upper left. Watering can be performed toward the blade portion 9 in any direction. An operation button (not shown) is provided on an operation panel of the cab 11 of the weight release machine 100, and can instruct the watering device 10 to start and stop watering. Similarly, an instruction to start and stop sending compressed air to the two-fluid nozzle 3b can be given.

図７は、環状パイプが８角形の散水装置１０の例である。環状パイプ１は、図１の円形に限らず、８角形にすることができる。   FIG. 7 is an example of the watering device 10 in which the annular pipe has an octagonal shape. The annular pipe 1 is not limited to the circular shape shown in FIG.

図８は、散水装置１０を大割ニブラ７０に適用した例である。散水装置１０は、鉄骨カッター６０と同様に、大割ニブラ７０の上部に取り付けることができる。取付ブラケット７は、上部から外側に突出するように取り付ける。大割ニブラ７０は、圧砕用の刃部があり、内部に備えた回動機構により回動できる。   FIG. 8 shows an example in which the sprinkler device 10 is applied to a large nibble 70. The watering device 10 can be attached to the upper part of the large nibble 70 similarly to the steel frame cutter 60. The mounting bracket 7 is mounted so as to protrude outward from the upper part. The large nibble 70 has a crushing blade, and can be rotated by a rotating mechanism provided therein.

散水装置１０は、金属板からなる保護カバー（図示せず）を設け、解体破片などがぶつかっても破損しないようにできる。樹脂発泡体からなる部材で環状パイプを覆うことでもよい。樹脂発泡体が割れることで衝撃を吸収する。圧送水には、水道水の他、タンクやプールに溜め置いた水や川の水も使用可能である。圧送水に０．１〜１％程度の界面活性剤を添加すると、水の表面張力を低下させることができる。表面張力が低下すれば、解体物の細部まで水が浸透する。そのため、アスベスト等の粉塵の飛散防止に効果がある。なお、水だけの散水に比べて散水量も少なくて済む。   The sprinkling device 10 is provided with a protective cover (not shown) made of a metal plate, so that it can be prevented from being broken even if a demolition debris hits. The annular pipe may be covered with a member made of a resin foam. The impact is absorbed by cracking of the resin foam. In addition to tap water, water stored in a tank or a pool or river water can be used for pumping water. When about 0.1 to 1% of a surfactant is added to the pumping water, the surface tension of the water can be reduced. If the surface tension is reduced, water penetrates into the details of the demolition. Therefore, it is effective in preventing scattering of dust such as asbestos. In addition, the amount of watering is smaller than watering only with water.

本発明は、重機アタッチメントの刃部を効率よく冷却できる散水装置として、また、燃えやすい材料が多い火力発電所などの解体重機として好適である。   INDUSTRIAL APPLICABILITY The present invention is suitable as a sprinkler capable of efficiently cooling the blade portion of a heavy equipment attachment, and as a weight release machine such as a thermal power plant having a large amount of easily combustible materials.
