この発明は多段圧延機の控ロール及び中間ロールの組替
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rearranging device for backing rolls and intermediate rolls of a multi-high rolling mill.
従来、作業ロールの外側に中間ロール、控ロール（支持
ロール）を備えた多段圧延機において、中間ロール及び
控ロールの組替は、ポーターバ一方式またはＣフツク方
式等により、中間ロール及び控ロールをクレーンで吊上
げた状態で移動して取替でおり、組替時におけるロール
の安定性が悪く、ロールの当庇や、作業上の危険性があ
った。Conventionally, in multi-high rolling mills equipped with intermediate rolls and backing rolls (support rolls) outside work rolls, the intermediate rolls and backing rolls are rearranged using porter bar type or C-hook type. The rolls were replaced while being lifted up by a crane, and the stability of the rolls during reassembly was poor, causing the rolls to overhang and pose a danger to the work.
また、組替時間が長くかかるとともに、組替作業者は２
名以上必要とし、作業も熟練を要し、よつて、組替作業
を簡単かつ短時間で行うことができず、圧延機の休止時
間が永くなり、生産性が低下する等の欠点があった。In addition, it takes a long time to reassemble, and the number of reassignment workers is 2.
The work required more than 1,000 people, and the work required skill.Therefore, there were drawbacks such as making it impossible to perform recombination work easily and in a short time, prolonging the down time of the rolling mill, and reducing productivity. .
従って、この発明は、控ロール及び中間ロールを、走行
台車上に取り外し自在に搭載する受台部材上に支承して
組替作業を行うようにしたもので、組替時のロールを安
定した状態で移動させること等により、安全、簡単、迅

行えるようにしたものである。Therefore, in this invention, the reassembly work is carried out by supporting the backing roll and the intermediate roll on a pedestal member that is removably mounted on a traveling truck, and the rolls are kept in a stable state during reassembly. The rearrangement work can be carried out safely, easily, quickly, and by a single person who does not require any skill by moving the parts by hand.

Old rolls 8a, 9a, 12a taken out to a, 15a
, 13a may be lifted up by a crane and carried out, or may be lifted up and carried out by a crane at the same time as the pedestal member.
また、下控ロールを組替える際は、下中間ロール及び下
作業ロールを下控ロール上に載せたまま一度に組替えて
もよい。Further, when rearranging the lower backing roll, the lower middle roll and the lower work roll may be rearranged at once while being placed on the lower backing roll.
この発明は上記実症例に限定されず、上下中間ロールを
多段に備えた場合にも、各段の中間ロール受台部材を台
車６上に取替可能に設けることにより、全く上記中間ロ
ールの組替と同様に組替えることができる。This invention is not limited to the above-mentioned actual case, and even when upper and lower intermediate rolls are provided in multiple stages, the intermediate roll pedestal member of each stage is replaceably provided on the trolley 6, so that the intermediate rolls can be completely assembled. It can be rearranged in the same way as replacement.
以上の説明より明らかなように、この発明に係るロール
組替装置によれば、控ロール及び中間ロールを軌条面上

に重量の大きいロールの場合、作業の危険性は少く、か
つ、ロールに損傷が生じることもない。As is clear from the above description, according to the roll changing device according to the present invention, the replacement work is carried out by supporting the backing roll and the intermediate roll on a pedestal member mounted on a truck that runs on a rail surface. During extrusion and retraction from the rolling mill, each roll slides and moves on a pedestal member, so it is stable, and especially in the case of heavy rolls, there is little risk of work and there is no risk of damage to the rolls. It never happens.
また、控ロールにおいては同時に各ロールを押出及び引
込みが自動的にでき、特に、ロール本数の多い場合には
作業時間の短縮化が図られ、効果を発揮する。Further, each of the backing rolls can be automatically pushed out and pulled in at the same time, which is particularly effective in shortening the working time when there are a large number of rolls.
かつ、上記の如く、控ロールは自動的に移送できると共
に、中間ロールも手動で受台部材上を摺動させて容易に
移送できるため、ロール組替作業は熟練を要せず、しか
も、一人で行うことができ、省力化が図れる。In addition, as mentioned above, the backing roll can be transferred automatically, and the intermediate roll can also be easily transferred by manually sliding it on the pedestal member, so the roll rearranging work does not require skill and can be carried out by just one person. This can be done by hand, saving labor.
さらに、上下控ロール受台部材及び上下中間ロール受台
部材を一つの台車上に取替えて搭載するようにしている
ため、構造が簡単であると共に、スペースをとらない。Furthermore, since the upper and lower retaining roll holder members and the upper and lower intermediate roll holder members are replaced and mounted on one truck, the structure is simple and does not take up much space.
また、各ロール中心との芯合せは、下ロール位置は不変
であり、上ロール位置は圧下装置を利用することにより
調整することができるので、ロール受台部材側には特別
な昇降手段を備える必要はなく、構造が極めて簡単であ
る。In addition, to align the center of each roll, the lower roll position remains unchanged and the upper roll position can be adjusted by using a rolling device, so a special elevating means is provided on the roll pedestal member side. It is not necessary and the structure is extremely simple.
しかも、台車は圧延作業時には作業フロアとなり、何ら
障害物とならない。Furthermore, the cart serves as a work floor during the rolling operation and does not pose any obstruction.
このように、本ロール組替装置は従来の欠点を解消する
と共に、新規な種々の効果を有し、実用的価値の大なる
ものである。As described above, the present roll changing device eliminates the drawbacks of the conventional device and has various new effects, and is of great practical value.
