Description
本発明は、原料搬送用コンベヤのヘッドプーリの表面に付着した原料を除去するベルトクリーナに関するものである。 The present invention relates to a belt cleaner that removes material adhering to the surface of a head pulley of a material conveying conveyor.
製鉄工場においては、石炭や鉄鉱石などの原料を搬送するために多くのベルトコンベヤが用いられている。搬送されてきた原料の大部分はベルト端部のヘッドプーリの部分で下方のシュートに排出されるが、その一部がベルトの表面に付着したままコンベヤのリターン側に移動し、ベルトコンベヤの下方にバラバラと落下することがある。 In a steel factory, many belt conveyors are used to convey raw materials such as coal and iron ore. Most of the material that has been transported is discharged to the lower chute at the head pulley at the end of the belt, but part of it moves to the return side of the conveyor while adhering to the belt surface. May fall apart.
そこで従来から、ベルト表面から付着物を除去するための様々なベルトクリーナが提案されてきた。その一例は特許文献１に示すように、ヘッドプーリの部分でベルトの表面に軸線と平行なクリーナチップを押し付け、ベルト表面の付着物を掻き落とす構造のものである。なおこの特許文献１では錘の重量を利用してベルトの表面にクリーナチップを押し付け、ヘッドプーリに無理な力が作用することがないように工夫されている。 Thus, various belt cleaners for removing deposits from the belt surface have been proposed. One example is a structure in which a cleaner tip parallel to the axis is pressed against the surface of the belt at the head pulley portion to scrape off deposits on the belt surface, as shown in Patent Document 1. In Patent Document 1, the weight of the weight is used to press the cleaner chip against the surface of the belt so that an excessive force does not act on the head pulley.
しかしこのような板状のクリーナチップは、ベルト表面やヘッドプーリの表面が偏摩耗した場合にはヘッドプーリの軸線方向における接触状態が不均一になり、完全な掻き落とし効果が得られなくなるという問題があった。また、ベルト表面の付着物に引っ掛かり、クリーナチップが破損することもあった。 However, such a plate-like cleaner chip has a problem that when the belt surface or the head pulley surface is worn unevenly, the contact state in the axial direction of the head pulley becomes non-uniform, and a complete scraping effect cannot be obtained. was there. In addition, the cleaner chip may be damaged by being caught on the belt surface.
なおこの問題を解決するために、ヘッドプーリの軸線方向にクリーナチップを分割したベルトクリーナも提案されている。しかしそのような分割式のベルトリーナも、シュート室の内部に立ち入らないと点検及び位置の調整ができないため、安全上の観点からコンベヤの休止期間中にしかメンテナンスを行うことができないという問題があった。 In order to solve this problem, a belt cleaner in which a cleaner chip is divided in the axial direction of the head pulley has also been proposed. However, such a split-type belt liner cannot be inspected and adjusted unless it enters the chute chamber, so that there is a problem that maintenance can be performed only during the conveyor pause period from the viewpoint of safety. It was.
従って本発明の目的は上記した従来の問題点を解決し、ベルトやヘッドプーリの偏摩耗が発生した場合にも十分な掻き落とし効果を達成することができ、しかもコンベヤの運転中にも外部から安全に位置の調節を行うことができるベルトクリーナを提供することである。 Therefore, the object of the present invention is to solve the above-mentioned conventional problems, and to achieve a sufficient scraping effect even when uneven wear of the belt or the head pulley occurs, and also from the outside during the operation of the conveyor. To provide a belt cleaner capable of safely adjusting the position.
上記の課題を解決するためになされた本発明は、原料搬送用コンベヤのヘッドプーリの表面に付着した原料を紐状クリーナによって除去するベルトクリーナであって、ヘッドプーリが収納されたシュート室の左右外側に、ヘッドプーリの回転軸を中心とする円弧状取付部材を配置し、当該円弧状取付部材は、ヘッドプーリの回転軸を中心とする内外２本の円弧状部材からなる無底の扇型形状であって、前記円弧状取付部材の外側面に半径方向部材が取り付けられ、当該半径方向部材は前記円弧状取付部材の外側面に密着する第１の平板と、この第１の平板に対して垂直な第２の平板を備え、当該第１の平板の半径方向の両端部がクランプによって前記円弧状取付部材に固定された構造であり、前記クランプはコの字状の断面とクランプボルトとを備え、前記半径方向部材を、前記円弧状取付部材に周方向の位置調節可能に固定され、前記半径方向部材の前記第２の平板には、長溝が形成され、当該長溝を貫通するボルトによって、前記紐状クリーナの端部支持部材が取り付けられ、当該端部支持部材は前記第２の平板に密着する第３の平板と、当該第３の平板に対して垂直な第４の平板とを備え、前記長溝を貫通するボルトを緩めることにより、前記端部支持部材の位置を半径方向に変更することができ、前記端部支持部材の前記第４の平板には、前記紐状クリーナの端部が支持され、張設されていることを特徴とするものである。 The present invention made to solve the above-mentioned problems is a belt cleaner that removes the material adhering to the surface of the head pulley of the material conveying conveyor with a string cleaner, and the right and left of the chute chamber in which the head pulley is accommodated. An arcuate mounting member centered on the rotational axis of the head pulley is disposed outside, and the arcuate mounting member is a bottomless fan-shaped member composed of two arcuate members inside and outside the rotational axis of the head pulley. A radial member is attached to the outer surface of the arcuate mounting member, the radial member being in close contact with the outer surface of the arcuate mounting member, and the first flat plate The first flat plate has a structure in which both ends of the first flat plate in the radial direction are fixed to the arcuate mounting member by a clamp, and the clamp has a U-shaped cross section and a clamp bolt. The radial member is fixed to the arcuate mounting member so that the circumferential position of the radial member can be adjusted, and a long groove is formed in the second flat plate of the radial member, and a bolt penetrating the long groove is used. The end support member of the string cleaner is attached, and the end support member includes a third flat plate that is in close contact with the second flat plate, and a fourth flat plate that is perpendicular to the third flat plate. The position of the end support member can be changed in the radial direction by loosening a bolt that penetrates the long groove, and the end of the string-like cleaner is provided on the fourth flat plate of the end support member. The portion is supported and stretched .
なお請求項２のように、前記円弧状取付部材をヘッドプーリの軸受よりも内側に配置した構造とすることが好ましい。また請求項３のように、前記端部支持部材は、前記紐状クリーナに張力を付与するスプリングを備えたものであることが好ましい。さらに請求項４のように、前記紐状クリーナは、ワイヤの外周に多数のセラミックチップを取付けたものであることが好ましい。 It is preferable that the arcuate mounting member is arranged on the inner side than the bearing of the head pulley. Moreover, it is preferable that the end support member includes a spring that applies tension to the string cleaner. Further, according to a fourth aspect of the present invention, it is preferable that the string cleaner has a large number of ceramic chips attached to the outer periphery of the wire.
本発明のベルトクリーナは、シュート室の左右外側に、ヘッドプーリの回転軸を中心とする円弧状取付部材を配置し、これらの円弧状取付部材に半径方向部材を周方向の位置調節可能に取り付けるとともに、各半径方向部材に紐状クリーナの端部支持部材を半径方向の位置調節可能に取り付けた構造である。このため紐状クリーナの両端を支持する端部支持部材を、ヘッドプーリの周方向にも半径方向にも自由に移動させることができる。このためヘッドプーリの表面に対する紐状クリーナの接触状態を自由に調節することができ、偏摩耗が発生した場合にも十分な掻き落とし効果を達成することができる。 In the belt cleaner of the present invention, arcuate mounting members centered on the rotation axis of the head pulley are arranged on the left and right outer sides of the chute chamber, and radial members are attached to these arcuate mounting members so that the position in the circumferential direction can be adjusted. And it is the structure which attached the edge part support member of the string-shaped cleaner to each radial direction member so that position adjustment of a radial direction is possible. Therefore, the end support members that support both ends of the string cleaner can be freely moved both in the circumferential direction and in the radial direction of the head pulley. For this reason, the contact state of the string cleaner with respect to the surface of the head pulley can be freely adjusted, and a sufficient scraping effect can be achieved even when uneven wear occurs.
しかも円弧状取付部材はヘッドプーリが収納されたシュート室の左右外側に配置されているので、シュート室の内部に入らなくても紐状クリーナの両端を支持する端部支持部材の調節が可能であり、コンベヤの運転中にも安全に位置の調節を行うことができる。 In addition, since the arcuate mounting members are arranged on the left and right outer sides of the chute chamber in which the head pulley is housed, it is possible to adjust the end support members that support both ends of the string cleaner without entering the chute chamber. Yes, the position can be adjusted safely while the conveyor is in operation.
以下に本発明の好ましい実施形態を示す。
図１は本発明の実施形態を示す正面図、図２はその一部省略側面図である。これらの図において、１は原料搬送用のベルトコンベヤ、２はその先端に配置されたヘッドプーリである。ヘッドプーリ２の回転軸３は門型フレーム４に設けられた左右一対の軸受５、５によって支持され、ベース６上に設置されたモータ７によって連続的に駆動されている。本実施形態のベルトコンベヤ１は鉄鉱石やコークスなどを高炉に搬送するためのものであるが、石炭やその他の原料搬送用のコンベヤであってもよいことはいうまでもない。
Preferred embodiments of the present invention are shown below.
FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a partially omitted side view thereof. In these drawings, 1 is a belt conveyor for conveying raw materials, and 2 is a head pulley arranged at the tip thereof. The rotating shaft 3 of the head pulley 2 is supported by a pair of left and right bearings 5 and 5 provided on the portal frame 4 and is continuously driven by a motor 7 installed on the base 6. Although the belt conveyor 1 of this embodiment is for conveying iron ore, coke, etc. to a blast furnace, it cannot be overemphasized that it may be a conveyor for coal and other raw material conveyance.
８はヘッドプーリ２が収納されているシュート室である。ベルトコンベヤ１によって搬送されてきた原料はヘッドプーリ２の先端からこのシュート室８の内部に排出され、下方に落下することは従来と同様である。 Reference numeral 8 denotes a chute chamber in which the head pulley 2 is accommodated. The raw material conveyed by the belt conveyor 1 is discharged from the tip of the head pulley 2 into the chute chamber 8 and falls downward as in the conventional case.
このシュート室８の左右の外側壁には、図３、図４に示すような円弧状取付部材９が設けられている。この円弧状取付部材９は、ヘッドプーリ２の回転軸３を中心とする内外２本の円弧状部材からなるもので、全体としては無底の扇型形状をしており、その外側面に半径方向部材１０が取り付けられている。この半径方向部材１０は円弧状取付部材９の外側面に密着する第１の平板１１と、この第１の平板１１に対して垂直な第２の平板１２を備えたものであり、第１の平板１１の半径方向の両端部をクランプ１３，１４によって円弧状取付部材９に固定する構造となっている。これらのクランプ１３，１４はコの字状の断面とクランプボルト１５とを備え、半径方向部材１０を円弧状取付部材９に、周方向の位置調節可能に固定することができる。このため、半径方向部材１０の周方向位置はシュート室８の外側から自由に調節することができる。 Arc mounting members 9 as shown in FIGS. 3 and 4 are provided on the left and right outer walls of the chute chamber 8. The arcuate mounting member 9 is composed of two inner and outer arcuate members centered on the rotation shaft 3 of the head pulley 2, and has a bottomless fan-like shape as a whole. A direction member 10 is attached. The radial member 10 includes a first flat plate 11 that is in close contact with the outer surface of the arcuate mounting member 9, and a second flat plate 12 that is perpendicular to the first flat plate 11. Both ends in the radial direction of the flat plate 11 are fixed to the arcuate mounting member 9 by clamps 13 and 14. These clamps 13 and 14 are provided with a U-shaped cross section and a clamp bolt 15, and the radial member 10 can be fixed to the arcuate mounting member 9 so that the position in the circumferential direction can be adjusted. Therefore, the circumferential position of the radial member 10 can be freely adjusted from the outside of the chute chamber 8.
図４に示すように、半径方向部材１０の第２の平板１２には、長溝１６が形成されている。そしてこの長溝１６を貫通する２本のボルト１７によって、紐状クリーナ１８の端部支持部材１９が取り付けられている。この端部支持部材１９は第２の平板１２に密着する第３の平板２０と、この第３の平板２０に対して垂直な第４の平板２１とを備えたもので、ボルト１７を緩めることにより、端部支持部材１９の位置を半径方向に変更することができる。 As shown in FIG. 4, a long groove 16 is formed in the second flat plate 12 of the radial member 10. The end support member 19 of the string-like cleaner 18 is attached by two bolts 17 penetrating the long groove 16. The end support member 19 includes a third flat plate 20 that is in close contact with the second flat plate 12 and a fourth flat plate 21 that is perpendicular to the third flat plate 20, and loosens the bolt 17. Thus, the position of the end support member 19 can be changed in the radial direction.
図５に示すように、端部支持部材１９の第４の平板２１には、紐状クリーナ１８の端部が支持されている。この実施形態の紐状クリーナ１８は、平行な２本のワイヤ２２の外周に多数のセラミックチップ２３を取付けたものであり、全体として自由に折れ曲がることができる。このため図２に示したようにヘッドプーリ２の表面に密着させることができる。セラミックチップ２３としては、例えばアルミナなどの硬質のセラミックスブロックが適している。 As shown in FIG. 5, the end of the string-like cleaner 18 is supported on the fourth flat plate 21 of the end support member 19. The string-like cleaner 18 of this embodiment has a large number of ceramic chips 23 attached to the outer periphery of two parallel wires 22 and can be bent freely as a whole. Therefore, it can be brought into close contact with the surface of the head pulley 2 as shown in FIG. As the ceramic chip 23, for example, a hard ceramic block such as alumina is suitable.
ワイヤ２２の端部は端部支持部材１９を貫通し、その外側のワイヤ折り返しガイド２４に巻かれている。ワイヤ折り返しガイド２４が設けられたブロック２５には張力調整用ボルト２６によってスプリング押さえ板２７が取り付けられている。またこのスプリング押さえ板２７と端部支持部材１９との間には、圧縮コイルスプリング２８が設けられ、ブロック２５を端部支持部材１９から離間させる方向の段発力を与えている。このためワイヤ２２はこのスプリングによって張力を付与され、紐状クリーナ１８をヘッドプーリ２の表面に密着させることができる。 The end of the wire 22 passes through the end support member 19 and is wound around the wire folding guide 24 on the outside thereof. A spring pressing plate 27 is attached to a block 25 provided with a wire folding guide 24 by a tension adjusting bolt 26. A compression coil spring 28 is provided between the spring pressing plate 27 and the end support member 19 to give a stepping force in a direction in which the block 25 is separated from the end support member 19. Therefore, the wire 22 is tensioned by the spring, and the string-like cleaner 18 can be brought into close contact with the surface of the head pulley 2.
図２に示すように、紐状クリーナ１８はヘッドプーリ２の表面を斜めに横切るように配置しておくことが好ましい。このため前記した円弧状取付部材９等は、ヘッドプーリ２の片側ではその回転軸３よりも高い位置に配置され、反対側では回転軸３よりも低い位置に配置されている。 As shown in FIG. 2, the string cleaner 18 is preferably arranged so as to cross the surface of the head pulley 2 obliquely. For this reason, the above-described arcuate mounting member 9 and the like are disposed at a position higher than the rotation shaft 3 on one side of the head pulley 2 and are disposed at a position lower than the rotation shaft 3 on the opposite side.
このように、自由に折れ曲がることができる紐状クリーナ１８を所定の張力でヘッドプーリ２の表面を横切るように配置しておけば、付着した原料を確実に掻き落とすことができる。しかも紐状クリーナ１８の両端を支持している端部支持部材１９の位置を周方向及び半径方向に自由に調節することができるので、ヘッドプーリ２やベルトが偏摩耗した場合にも、紐状クリーナ１８の支持位置を変えて最適な接触状態とすることができる。なお、円弧状取付部材９を、ヘッドプーリ２の軸受５，５よりも内側に配置してあるため、軸受５，５が邪魔になることもない。 Thus, if the string-like cleaner 18 that can be bent freely is arranged so as to cross the surface of the head pulley 2 with a predetermined tension, the attached raw material can be surely scraped off. In addition, since the position of the end support member 19 that supports both ends of the string cleaner 18 can be freely adjusted in the circumferential direction and the radial direction, even when the head pulley 2 or the belt is worn unevenly, the string shape The support position of the cleaner 18 can be changed to achieve an optimum contact state. Since the arcuate mounting member 9 is disposed inside the bearings 5 and 5 of the head pulley 2, the bearings 5 and 5 do not get in the way.
さらに本発明では端部支持部材１９をシュート室８の左右外側に配置したので、シュート室８の外側から端部支持部材１９の位置を調節することができる。このため危険なシュート室８の内部に入る必要がなく、ベルトコンベヤ１の運転中にも紐状クリーナ１８の支持位置を自由に調節することができる。 Further, in the present invention, since the end support member 19 is disposed on the left and right outer sides of the chute chamber 8, the position of the end support member 19 can be adjusted from the outer side of the chute chamber 8. For this reason, it is not necessary to enter the inside of the dangerous chute chamber 8, and the support position of the string cleaner 18 can be freely adjusted even during the operation of the belt conveyor 1.
以上に説明したように、本発明のベルトクリーナは、ヘッドプーリ２等に偏摩耗が発生した場合にも十分な掻き落とし効果を達成することができ、しかもコンベヤの運転中にも外部から安全に位置の調節を行うことができる利点がある。この結果、コークス搬送用コンベヤのリターン側への原料付着量をゼロとすることが可能となった。 As described above, the belt cleaner of the present invention can achieve a sufficient scraping effect even when uneven wear occurs in the head pulley 2 and the like, and can be safely externally during the operation of the conveyor. There is an advantage that the position can be adjusted. As a result, the amount of raw material attached to the return side of the coke conveyor can be reduced to zero.
