Description

本発明はバケットコンベアのバケット取付用座金に関するものである。   The present invention relates to a bucket mounting washer for a bucket conveyor.

フェロニッケル製錬などの金属製錬においては、製錬炉から排出される高温のスラグに高圧の水砕水を加えて粉砕するいわゆる水砕処理が行われている。かかる水砕処理で水砕されたスラグは水砕水と共にピットに一旦溜められた後、バケットコンベアで連続的にすくい取ってピットから取り出される。バケットコンベアには、例えば特許文献１に示すような無端ベルトに複数のバケットを取り付けた構造のものや、リンクチェーンに複数のバケットを取り付けた構造のものが用いられている。   In metal smelting such as ferronickel smelting, so-called granulation processing is performed in which high-pressure granulated water is added to high-temperature slag discharged from a smelting furnace and pulverized. The slag that has been crushed by the water granulation treatment is once stored in the pit together with the water crushed water, and then is continuously picked up by a bucket conveyor and taken out from the pit. For example, a bucket conveyor having a structure in which a plurality of buckets are attached to an endless belt as shown in Patent Document 1 or a structure in which a plurality of buckets are attached to a link chain is used.

バケットコンベアのバケットは一般にボルトによって無端ベルトやリンクチェーンに取り付けられている。例えばリンクチェーンにバケットを取り付ける場合は、リンクチェーンに穿孔されたバケット取付用のボルト挿通孔及びバケットの取付部においてこれに対応する位置に穿孔されたボルト挿通孔にリンクチェーン側からボルトを挿通し、バケットの内側に突出する該ボルトの先端部に平ワッシャ及びスプリングワッシャをこの順に嵌装した後、ナットを螺合させることでバケットの取り付けが行われる。   A bucket of a bucket conveyor is generally attached to an endless belt or a link chain by bolts. For example, when attaching a bucket to the link chain, insert the bolt from the link chain side into the bolt insertion hole for attaching the bucket drilled in the link chain and the bolt insertion hole drilled at the corresponding position in the bucket mounting part. Then, a flat washer and a spring washer are fitted in this order on the tip of the bolt protruding inside the bucket, and then the bucket is attached by screwing a nut.

実開平４−２９５１７号公報Japanese Utility Model Publication No. 4-29517

上記したようなバケットコンベアのバケットでピット内に堆積したスラグをすくい取るときは、バケットに大きな荷重がかかる上、ピット内のスラグは水砕処理されてはいるものの依然として高温状態にあるため、バケットはかかる高温のスラグによって熱せられる。このように水砕処理されたスラグを搬出するバケットコンベアのバケットには荷重及び熱による負荷が繰り返しかかることになる。そのため、バケットをリンクチェーンに締結する上記ボルトが徐々に伸びるのを避けることはできない。   When scooping slag accumulated in the pit with the bucket of the bucket conveyor as described above, a heavy load is applied to the bucket, and the slag in the pit is still in a high temperature state although it is still water-granulated. Is heated by such hot slag. In this way, the load of the bucket conveyor which carries out the slag subjected to the water granulation treatment is repeatedly subjected to load and heat. Therefore, it cannot be avoided that the bolt for fastening the bucket to the link chain is gradually extended.

このボルトの伸びがスプリングワッシャの伸縮範囲を超えると、リンクチェーンとバケットの取付部との間の締結力が失われる。その結果、以下の２つの問題が発生して最終的にバケットがリンクチェーンから脱落してしまう。すなわち１つめの問題は、バケットの取付部と平ワッシャとの間に隙間が生じ、ここにスラグが浸入してバケットの取付部が摩耗する問題である。この摩耗によりバケットの取付部の肉厚がスラグを搭載したバケット自身を支持可能な限度を超えて減肉すると、当該減肉した箇所を起点としてバケットが破れ、最終的にバケットが脱落してしまう。   When the extension of the bolt exceeds the expansion / contraction range of the spring washer, the fastening force between the link chain and the attachment portion of the bucket is lost. As a result, the following two problems occur, and the bucket eventually falls off the link chain. That is, the first problem is a problem in which a gap is generated between the attachment portion of the bucket and the flat washer, and the slag enters here and the attachment portion of the bucket is worn. If the wall thickness of the attachment portion of the bucket is reduced beyond this limit that can support the bucket on which the slag is mounted due to this wear, the bucket will be broken starting from the thinned portion, and the bucket will eventually fall off. .

２つめの問題は、リンクチェーンとバケットの取付部との間の締結力が失われた状態でバケットコンベアの運転を続けると、バケットがリンクチェーンに取り付けられていた当初位置からずれやすくなる問題である。このようにバケットがずれやすくなると、バケットの取付部に設けたボルト挿通孔の内周部分とボルトの外周部分との衝突や摺動が繰り返されることで摩耗し、当該ボルト挿通孔が徐々に拡大する。そして、この拡大したボルト挿通孔の内径が平ワッシャの外径より大きくなると、バケットが脱落してしまう。   The second problem is that if the operation of the bucket conveyor is continued in a state where the fastening force between the link chain and the attachment portion of the bucket is lost, the bucket is likely to be displaced from the original position where it was attached to the link chain. is there. When the bucket is easily displaced in this way, it is worn out by repeated collisions and sliding between the inner peripheral portion of the bolt insertion hole provided in the bucket mounting portion and the outer peripheral portion of the bolt, and the bolt insertion hole gradually expands. To do. When the enlarged inner diameter of the bolt insertion hole is larger than the outer diameter of the flat washer, the bucket falls off.

本発明は上記した従来の問題に鑑みてなされたものであり、バケットコンベアのリンクチェーンからバケットが脱落する要因となる上記した２つの問題の発生を抑えることが可能なバケットコンベアのバケット取付用座金を提供することを目的としている。   The present invention has been made in view of the above-mentioned conventional problems, and is a bucket washer for attaching a bucket of a bucket conveyor that can suppress the occurrence of the above-mentioned two problems that cause the bucket to drop off from the link chain of the bucket conveyor. The purpose is to provide.

上記目的を達成するため、本発明に係るバケット取付用座金は、リンクチェーンとこれにボルトで取り付けられた複数のバケットとからなるバケットコンベアにおける各バケットの取付部に用いるバケット取付用座金であって、１枚の湾曲したバネ板とこれを両面から挟み込む２枚の金属板とからなり、該バネ板はその湾曲方向の中央部と両端部との少なくとも３箇所にそれぞれボルトが挿通するボルト挿通孔を有しており、該両端部のボルト挿通孔は該湾曲方向に延びる長孔であることを特徴としている。   In order to achieve the above object, a bucket mounting washer according to the present invention is a bucket mounting washer used for a mounting portion of each bucket in a bucket conveyor composed of a link chain and a plurality of buckets attached thereto with bolts. A bolt insertion hole that includes one curved spring plate and two metal plates sandwiching the spring plate from both sides, and the spring plate is inserted into at least three locations of the center portion and both end portions in the bending direction. The bolt insertion holes at both ends are elongated holes extending in the bending direction.

本発明によれば、バケットコンベアのリンクチェーンからバケットが脱落する問題を防ぐことができる。   ADVANTAGE OF THE INVENTION According to this invention, the problem that a bucket falls from the link chain of a bucket conveyor can be prevented.

本発明の一具体例のバケット取付用座金を用いて締結されたバケットを有するバケットコンベアの模式的な正面図である。It is a typical front view of the bucket conveyor which has the bucket fastened using the washer for bucket attachment of one specific example of this invention. 本発明の一具体例のバケット取付用座金の分解斜視図である。It is a disassembled perspective view of the washer for bucket attachment of one example of the present invention.

以下、本発明のバケット取付用座金の一具体例について図面を参照しながら説明する。図１にはリンクチェーン１とこれにボルト２で取り付けられた複数のバケット３とからなるバケットコンベア４が示されており、このバケットコンベア４によりピットＰ内に水砕水と共に貯められている水砕処理後の高温スラグＳがピットＰから連続的に取り出される。本発明の一具体例のバケット取付用座金１０は、各バケット３のリンクチェーン１への取付部に用いられている。   Hereinafter, a specific example of the bucket mounting washer of the present invention will be described with reference to the drawings. FIG. 1 shows a bucket conveyor 4 composed of a link chain 1 and a plurality of buckets 3 attached thereto with bolts 2. Water stored in the pit P together with crushed water by the bucket conveyor 4. The high-temperature slag S after the crushing process is continuously taken out from the pits P. A bucket mounting washer 10 according to a specific example of the present invention is used in a mounting portion of each bucket 3 to the link chain 1.

バケット取付用座金１０は、図２に示すように、矩形の金属板を湾曲させたバネ板１１とこれを両面から挟み込む互いに略同サイズの２枚の矩形の金属板１２、１３とからなる。バネ板１１はその湾曲方向の中央部と両端部との計３箇所にボルト２がそれぞれ挿通するボルト挿通孔１１ａ、１１ｂが設けられている。また、バネ板１１の凹側湾曲面に対向する金属板１２（以降、下側金属版とも称する）においてバネ板１１のボルト挿通孔１１ａ、１１ｂにそれぞれ対応する位置にボルト挿通孔１２ａ、１２ｂが設けられており、同様にバネ板１１の凸側湾曲面に対向する金属板１３（以降、上側金属版とも称する）においてバネ板１１のボルト挿通孔１１ａ、１１ｂにそれぞれ対応する位置にボルト挿通孔１３ａ、１３ｂが設けられている。なお、本明細書において湾曲方向とは図２の矢印Ａで示すようにバネ板１１の面上に沿った曲げの方向を意味しており、図２に示すように長方形のバネ板１１をその長手方向に沿って曲げる場合は湾曲方向は長手方向となる。   As shown in FIG. 2, the bucket mounting washer 10 includes a spring plate 11 obtained by curving a rectangular metal plate and two rectangular metal plates 12 and 13 having substantially the same size and sandwiching the spring plate 11 from both sides. The spring plate 11 is provided with bolt insertion holes 11a and 11b through which the bolts 2 are respectively inserted at a total of three locations of the central portion and both end portions in the bending direction. Further, in the metal plate 12 (hereinafter also referred to as a lower metal plate) facing the concave curved surface of the spring plate 11, bolt insertion holes 12a and 12b are provided at positions corresponding to the bolt insertion holes 11a and 11b of the spring plate 11, respectively. A bolt insertion hole is provided at a position corresponding to each of the bolt insertion holes 11a and 11b of the spring plate 11 in a metal plate 13 (hereinafter also referred to as an upper metal plate) that is provided and similarly opposed to the convex curved surface of the spring plate 11. 13a and 13b are provided. In this specification, the bending direction means the direction of bending along the surface of the spring plate 11 as shown by the arrow A in FIG. 2, and the rectangular spring plate 11 is shown in FIG. When bending along the longitudinal direction, the bending direction is the longitudinal direction.

バネ板１１において中央部のボルト挿通孔１１ａを除いた両端部のボルト挿通孔１１ｂはバネ板１１の湾曲方向に延びる長孔になっている。なお、図２にはバネ板１１及び金属板１２、１３の各々の両端部に１個ずつボルト挿通用の長孔を設けた例が示されているが、これに限定されるものではなく、両端部に２個以上ずつボルト挿通用の長孔を設けてもよい。   In the spring plate 11, the bolt insertion holes 11 b at both ends excluding the central bolt insertion hole 11 a are elongated holes extending in the bending direction of the spring plate 11. In addition, although the example which provided the elongate hole for bolt insertion one each in the both ends of each of the spring board 11 and the metal plates 12 and 13 is shown in FIG. 2, it is not limited to this, Two or more elongated holes for inserting bolts may be provided at both ends.

上記した図２の構成により、バケット３に高温のスラグＳの熱及び荷重が繰り返しかかってボルト２に伸びが生じても、このボルト２の伸び量よりも厚み方向に大きく変形可能なバネ板１１を使用することでリンクチェーン１とバケット３との締結力が低下したり、締結力が失われるのを防ぐことができる。これにより、座金の役割を担う下側金属板１２とバケット３の取付部との間に隙間が生じにくくなり、当該隙間にスラグＳが浸入してバケット３の取付部が摩耗したりバケット３がずれてボルト挿通孔が大きくなったりする問題を防ぐことができる。   With the configuration of FIG. 2 described above, even when the heat and load of the high-temperature slag S are repeatedly applied to the bucket 3 and the bolt 2 is stretched, the spring plate 11 can be deformed to be larger in the thickness direction than the bolt 2 is stretched. It is possible to prevent the fastening force between the link chain 1 and the bucket 3 from being reduced or the fastening force from being lost. Thereby, it becomes difficult to produce a clearance gap between the lower metal plate 12 which plays the role of a washer, and the attachment part of the bucket 3, and the attachment part of the bucket 3 is worn out due to the slag S entering the gap or the bucket 3 being worn. It is possible to prevent a problem that the bolt insertion hole is displaced and becomes large.

本発明の一具体例のバケット取付用座金１０においては、ボルトで締め付ける前の応力がかからない状態のバネ板１１とこれを挟んだ２枚の金属板１２、１３との計３枚を重ね合わせたときの合計の高さが３０ｍｍ以下であることが好ましい。すなわち、バネ板１１及び２枚の金属板１２、１３の厚さを各々好適な厚さである３.２ｍｍにした時、バネ板１１が湾曲状態から平板状態に変形する時の厚み方向の変形量が２０ｍｍ以下であるのが好ましい。なお、上記変形量はバネ板１１をその凹側湾曲面を下にして応力をかけずに床面に置いた時、バネ板１１の湾曲方向中央部と床面との間の距離と考えることができる。   In the bucket mounting washer 10 of one specific example of the present invention, a total of three spring plates 11 in a state where no stress is applied before tightening with bolts and two metal plates 12 and 13 sandwiching the spring plate 11 are overlapped. The total height is preferably 30 mm or less. That is, when the thickness of the spring plate 11 and the two metal plates 12 and 13 is set to a suitable thickness of 3.2 mm, the deformation in the thickness direction when the spring plate 11 is deformed from the curved state to the flat plate state. The amount is preferably 20 mm or less. The amount of deformation is considered to be the distance between the center of the spring plate 11 in the bending direction and the floor surface when the spring plate 11 is placed on the floor surface without applying stress to the concave curved surface. Can do.

上記した合計高さが３０ｍｍを超えると、例えば既存のバケットコンベアに使用している従来のスプリングワッシャと平ワッシャとからなるバケット取付用座金を本発明の一具体例のバケット取付用座金１０に入れ替えた時に、これら従来のスプリングワッシャ及び平ワッシャの合計厚みよりバケット取付用座金１０の厚みの方が厚くなってボルトの長さが足りなくなるおそれがある。この場合、従来のボルトより長いボルトを用いて対応すると、ボルトが熱せられた時にその長さ方向の伸びが従来より大きくなってしまうので本発明の一具体例のバケット取付用座金を用いることにより得られる効果が減少するおそれがある。   When the above total height exceeds 30 mm, for example, a conventional washer for mounting a bucket consisting of a spring washer and a flat washer used for an existing bucket conveyor is replaced with a bucket mounting washer 10 according to a specific example of the present invention. When this occurs, the thickness of the bucket mounting washer 10 may be thicker than the total thickness of these conventional spring washers and flat washers, and the bolt length may be insufficient. In this case, if a bolt longer than the conventional bolt is used, when the bolt is heated, the elongation in the length direction becomes larger than the conventional bolt. Therefore, by using the bucket mounting washer of one specific example of the present invention, The obtained effect may be reduced.

本発明の一具体例のバケット取付用座金１０は、バネ板１１の湾曲方向中央部に設けられるボルト挿通孔１１ａの内径が、バネ板１１の幅の１／２.５以下であることが好ましい。ボルト挿通孔１１ａの内径がバネ板１１の幅の１／２.５を超えるとバネ板１１が湾曲方向中央部で折れ曲がる可能性があるからである。また、バネ板１１の両端部に設けられる長孔のボルト挿通孔１１ｂは、その長手方向の開口長さが、バネ板１１が湾曲状態から平板状態に変形する際の湾曲方向の全体的な変形量の１／２をボルトの外径に加えた長さ以上であるのが好ましい。   In the bucket mounting washer 10 of one specific example of the present invention, it is preferable that the inner diameter of the bolt insertion hole 11 a provided in the central portion in the bending direction of the spring plate 11 is 1 / 2.5 or less of the width of the spring plate 11. . This is because if the inner diameter of the bolt insertion hole 11a exceeds 1 / 2.5 of the width of the spring plate 11, the spring plate 11 may be bent at the center in the bending direction. In addition, the elongated bolt insertion holes 11b provided at both ends of the spring plate 11 have an opening length in the longitudinal direction that is an overall deformation in the bending direction when the spring plate 11 is deformed from the bent state to the flat plate state. It is preferable that the length is equal to or more than a length obtained by adding 1/2 of the amount to the outer diameter of the bolt.

本発明の一具体例のバケット取付用座金１０のバネ板１１は、その湾曲方向の両縁部において、凹側湾曲面側の角部が面取りされているのが好ましい。これにより、バネ板１１がボルト２の伸縮などの応力を受けて変形する際、バネ板１１の両縁部の凹側湾曲面側の角部と下側金属板１２のバネ板１１との対向面側の端部とが集中的に接触するのを抑制することができる。その結果、下側金属板１２の当該接触箇所が摩耗により窪んでそこにバネ板１１の角部が食い込んでバネ板１１が自在に伸縮しにくくなるのを防ぐことができる。   The spring plate 11 of the bucket mounting washer 10 of one specific example of the present invention preferably has chamfered corners on the concave curved surface side at both edges in the bending direction. As a result, when the spring plate 11 is deformed by receiving stress such as expansion and contraction of the bolt 2, the corners on the concave curved surface side of both edges of the spring plate 11 and the spring plate 11 of the lower metal plate 12 are opposed to each other. It is possible to suppress intensive contact with the end portion on the surface side. As a result, it is possible to prevent the contact portion of the lower metal plate 12 from being dented due to wear, and the corners of the spring plate 11 from biting into the contact portion, thereby making it difficult for the spring plate 11 to freely expand and contract.

バネ板１１の角部の面取りは、例えばバネ板１１の縁部の断面形状が孤状になるようにするのが好ましい。このように断面形状を孤状にする事により、バネ板１１の両縁部が下側金属板１２にかかる力を簡易に分散させることができ、よって上記した下側金属板１２のバネ板１１との対向面への集中的な接触による摩耗が生じにくくなる。具体的にはバネ板１１の両縁部の各断面形状をＲ１.６ｍｍ以上の弧状となるように面取りすることが好ましい。   The corners of the spring plate 11 are preferably chamfered so that, for example, the cross-sectional shape of the edge of the spring plate 11 becomes an arc shape. Thus, by making the cross-sectional shape solitary, both edges of the spring plate 11 can easily disperse the force applied to the lower metal plate 12, and thus the spring plate 11 of the lower metal plate 12 described above. Wear due to intensive contact with the opposite surface is less likely to occur. Specifically, it is preferable to chamfer each cross-sectional shape of both edge portions of the spring plate 11 so as to have an arc shape of R1.6 mm or more.

本発明の一具体例のバケット取付用座金１０では、バネ板１１の凹側湾曲面に対向する下側金属板１２において、少なくともバネ板１１の両縁部が接し得る部分が硬化処理されているのが好ましい。この部分を硬化処理することより、バネ板１１がボルト２の伸縮などの応力で変形する際、バネ板１１の上記した角部と下側金属板１２のバネ板１１との対向面側の端部が集中的に接触しても、該接触箇所において摩耗が生じにくくなる。よって、上記した窪みによるバネ板１１の自在な伸縮の阻害の問題の発生をより一層抑制することができる。   In the bucket mounting washer 10 according to one specific example of the present invention, at least a portion of the lower metal plate 12 facing the concave curved surface of the spring plate 11 that can contact both edges of the spring plate 11 is cured. Is preferred. By curing this portion, when the spring plate 11 is deformed by a stress such as expansion and contraction of the bolt 2, the end on the opposite surface side between the above-described corner portion of the spring plate 11 and the spring plate 11 of the lower metal plate 12. Even if the parts come into contact intensively, wear is less likely to occur at the contact points. Therefore, the generation | occurrence | production of the problem of inhibition of the flexible expansion-contraction of the spring board 11 by an above described depression can be suppressed further.

また、本発明の一具体例のバケット取付用座金１０では、バネ板１１の凸側湾曲面に対向する上側金属板１３において、少なくともバネ板１１と対向する面の中央部が硬化処理されているのが好ましい。この部分を硬化処理することにより、バネ板１１がボルト２の伸縮などによる応力で変形する際、該バネ板１１の中央部と上側金属板１３の中央部とが集中的に接触しても該接触箇所において摩耗が生じにくくなる。よって、上側金属板１３がその中央部で破断するトラブルを防ぐことができる。   Further, in the bucket mounting washer 10 of one specific example of the present invention, at least the central portion of the surface facing the spring plate 11 is hardened in the upper metal plate 13 facing the convex curved surface of the spring plate 11. Is preferred. By curing this portion, when the spring plate 11 is deformed by the stress due to expansion and contraction of the bolt 2, even if the central portion of the spring plate 11 and the central portion of the upper metal plate 13 are intensively contacted, Wear is less likely to occur at the contact point. Therefore, the trouble which the upper side metal plate 13 fractures | ruptures in the center part can be prevented.

上記したように、下側金属板１２の少なくとも端部と上側金属板１３の少なくとも中央部とを硬化処理する事により、下側金属板１２のバネ板１１との対向面側の端部に接触するバネ板１１の凹部湾曲面側の角部、及び上側金属板１３のバネ板１１との対向面側の中央部に接触するバネ板１１の凸部湾曲面側の中央部の摩耗が進行しやすくなる。しかし、上記したように、バネ板１１の両縁部を面取りすることである程度摩耗の進行を抑えることができる。また、摩耗が進んだ場合であってもバネ板１１のみを取り換えれば良いので経済的である。なお、硬化処理の例としては焼き入れ処理を挙げることができる。   As described above, at least the end portion of the lower metal plate 12 and at least the center portion of the upper metal plate 13 are hardened so as to contact the end portion of the lower metal plate 12 facing the spring plate 11. Wear of the central portion on the convex curved surface side of the spring plate 11 that contacts the corner portion on the concave curved surface side of the spring plate 11 and the central portion of the upper metal plate 13 on the surface facing the spring plate 11 proceeds. It becomes easy. However, as described above, the progress of wear can be suppressed to some extent by chamfering both edges of the spring plate 11. Further, even if the wear progresses, it is economical because only the spring plate 11 needs to be replaced. An example of the curing process is a quenching process.

本発明の一具体例のバケット取付用座金１０では、下側金属板１２と上側金属板１３とで挟まれた内側空間をバケット３内の空間から隔離するように、例えば金属製の四角筒状体等の隔離手段で該内側空間を囲んでもよい。このように隔離手段でバケット取付用座金１０の内側空間を囲むことで該内側空間にスラグが侵入するのを防ぐことができるので、上記した下側金属板１２、上側金属板１３及びバネ板１１やこれらを締結するボルトの摩耗をより確実に抑えることができる。   In the bucket mounting washer 10 of one specific example of the present invention, for example, a metal rectangular tube shape is used so that the inner space sandwiched between the lower metal plate 12 and the upper metal plate 13 is isolated from the space in the bucket 3. The inner space may be surrounded by a separating means such as a body. Thus, by surrounding the inner space of the bucket mounting washer 10 with the separating means, it is possible to prevent the slag from entering the inner space, so the lower metal plate 12, the upper metal plate 13 and the spring plate 11 described above. Further, it is possible to more reliably suppress wear of the bolts for fastening them.
