Description

上ノズル引抜装置Upper nozzle drawing device
　本発明は、取鍋やタンディッシュ等の溶融金属容器の底部に設置され、溶融金属を排出するためのノズルとして使用される上ノズルを溶融金属容器から引き抜いて取り外すための上ノズル引抜装置に関する。 The present invention relates to an upper nozzle pulling device that is installed at the bottom of a molten metal container such as a ladle or a tundish and that is used as a nozzle for discharging the molten metal to pull out and remove the upper nozzle from the molten metal container.
　上ノズルは、取鍋やタンディッシュ等の溶融金属容器から溶融金属を排出するために、溶融金属容器の底部に設置されて使用される。 The upper nozzle is installed and used at the bottom of the molten metal container in order to discharge the molten metal from a molten metal container such as a ladle or tundish.
　この上ノズルは、寿命になると新しい上ノズルに交換するために溶融金属容器から取り外さなければならない。例えば、取鍋から上ノズルを取り外すためには、取鍋の内部から押し出す方法と取鍋の外側から引き抜く方法がある。 This upper nozzle must be removed from the molten metal container at the end of its life in order to replace it with a new upper nozzle. For example, in order to remove the upper nozzle from the ladle, there are a method of pushing out from the inside of the ladle and a method of pulling out from the outside of the ladle.
　このうち、上ノズルを取鍋の外側から引き抜く方法として、特許文献１に開示された方法が知られている。この特許文献１の方法は、図８に示すように引抜棒６の先端部に変位部材１１を設け、この変位部材１１が上ノズル４の溶湯通路を通過してからこれを変位させて上ノズル４と係合させ、次いで引抜棒６を引抜装置の駆動力で引き抜くというものである。引抜装置としては、台板１０にシリンダー作動装置７を固設し、この台板１０の中心部にシリンダー作動装置７によって移動する筒軸８を設けている。 Among these, the method disclosed in Patent Document 1 is known as a method of pulling out the upper nozzle from the outside of the pan. In the method of Patent Document 1, a displacement member 11 is provided at the distal end portion of the pull-out rod 6 as shown in FIG. 4 and then the extraction rod 6 is extracted by the driving force of the extraction device. As a drawing device, a cylinder operating device 7 is fixed to a base plate 10, and a cylindrical shaft 8 that is moved by the cylinder operating device 7 is provided at the center of the base plate 10.
　しかし、特許文献１では、上ノズルを引き抜くために専用のシリンダーを具備し、使用する必要がある。このように上ノズルの引抜作業用の専用のシリンダーを使用する場合、引抜作業時にシリンダーを作動させるために油圧ホースが必要となる。油圧ホースは固くて重いため、ホースの取り出し、移動、着脱、収納等の各作業に手間を要する問題がある。さらに、油圧ホースを床を這わせた場合には作業者がつまずく原因となる可能性もあり、安全の面での問題もある。 However, in Patent Document 1, it is necessary to use a dedicated cylinder for pulling out the upper nozzle. In this way, when a dedicated cylinder for the upper nozzle pulling operation is used, a hydraulic hose is required to operate the cylinder during the pulling operation. Since the hydraulic hose is hard and heavy, there is a problem that each operation such as taking out, moving, attaching / detaching, and storing the hose requires time. Furthermore, if the hydraulic hose is turned on the floor, it may cause the operator to stumble, and there is a problem in terms of safety.

　本発明が解決しようとする課題は、油圧ホースの着脱や移動が不要であり、簡便で安全な作業が実施可能な上ノズル引抜装置を提供することにある。 The problem to be solved by the present invention is to provide an upper nozzle pulling device that does not require attachment or detachment or movement of a hydraulic hose and can perform a simple and safe operation.
　上記課題を解決するために本発明者らは、溶融金属容器の底部には上ノズルとともにスライディングノズル装置が設置されることが多いことに注目し、このスライディングノズル装置の駆動装置による駆動力を、上ノズルを引き抜くための駆動力として利用しようという着想を得、本発明に想到した。 In order to solve the above problems, the present inventors have noted that a sliding nozzle device is often installed together with the upper nozzle at the bottom of the molten metal container, and the driving force by the driving device of this sliding nozzle device is The idea of using it as a driving force for pulling out the upper nozzle was obtained and the present invention was conceived.
　すなわち本発明の一観点によれば、次の上ノズル引抜装置が提供される。
「溶融金属容器の底部にスライディングノズル装置とともに設置された上ノズルを引き抜くための上ノズル引抜装置であって、
　上ノズルに係合可能な係合部を有する引抜ロッドと、駆動方向変換機とを備え、
　駆動方向変換機が、スライディングノズル装置のプレートを摺動させる駆動装置による駆動力の方向をプレートの摺動方向に対して垂直な方向に変換して引抜ロッドに伝達する、上ノズル引抜装置。」 That is, according to one aspect of the present invention, the following upper nozzle drawing device is provided.
“It is an upper nozzle pulling device for pulling out the upper nozzle installed together with the sliding nozzle device at the bottom of the molten metal container,
A drawing rod having an engaging portion engageable with the upper nozzle, and a driving direction changer;
An upper nozzle pulling device in which a driving direction changer converts the direction of the driving force by the driving device that slides the plate of the sliding nozzle device into a direction perpendicular to the sliding direction of the plate and transmits it to the pulling rod. "
　本発明によれば、上ノズルを引き抜くための駆動力としてスライディングノズル装置に元々ある駆動装置の駆動力を利用することから、従来のように、上ノズルを引き抜くために専用のシリンダーを具備し使用する必要がなくなり、油圧ホースの着脱や移動が不要となる。したがって、上ノズルの引抜作業の作業負荷が軽減し、作業能率が向上し、しかもより安全な作業が実施可能となる。 According to the present invention, the driving force of the driving device originally provided in the sliding nozzle device is used as the driving force for pulling out the upper nozzle, so that a conventional cylinder is used for pulling out the upper nozzle as in the prior art. This eliminates the need for attaching / detaching and moving the hydraulic hose. Therefore, the work load of the upper nozzle pull-out operation is reduced, the work efficiency is improved, and safer work can be performed.

A sliding nozzle device 400 is installed at the bottom of the ladle 200 together with the upper nozzle 300. Specifically, the upper plate of the sliding nozzle device 400 is connected to the lower end of the upper nozzle 300.
　スライディングノズル装置４００は、取鍋２００の底部に固定された固定金枠４１０と、固定金枠４１０に対して摺動可能（スライド可能）かつ開閉可能に設けたスライド金枠４２０と、固定金枠４１０に対して開閉可能に設けた２つのバネボックス４３０とを備える。バネボックス４３０には面圧を負荷するためのバネが設けられている。また、固定金枠４１０には上プレートが、スライド金枠４２０には下プレート４４０が保持固定されている。さらに、固定金枠４１０にはスライド金枠４２０（下プレート４４０）を固定金枠４１０（上プレート）に対して直線的に摺動させるための駆動装置としての油圧シリンダー４５０が取り付けられている。すなわち、プレートの摺動方向とは図２に示す矢印Ａの方向である。 The sliding nozzle device 400 includes a fixed metal frame 410 fixed to the bottom of the ladle 200, a slide metal frame 420 that is slidable (slidable) and can be opened and closed with respect to the fixed metal frame 410, and a fixed metal frame.

One vertical guide 125 is provided with a holding portion 126 for lifting the upper nozzle pulling device, and the other vertical guide 125 is provided with a holding portion 127 for holding by hand.
　ロッドホルダー１３０は、上述した２つの垂直ガイド１２５（垂直面１２５ａ及びガイドレール１２５ｂ）のガイド作用によって、プレートの摺動方向への移動が規制され、かつプレートの摺動方向に対して垂直方向に移動することが可能となっている。このロッドホルダー１３０は、引抜ロッド１７０が貫通するための円筒体１３１から続く第２の貫通孔１３２を有し、ロッドホルダー１３０の固定金枠側にプレートの摺動方向と垂直な方向に向けて傾斜する第２の摺動部として傾斜面１３３を有している。さらに、ロッドホルダー１３０のプレートの摺動方向とは垂直な２つの側面１３４は、それぞれ垂直ガイド１２５の垂直面１２５ａと摺動接触可能な摺動面（摺動部）となっており、しかも垂直ガイド１２５のガイドレール１２５ｂにガイド（案内）されるための溝１３５を有している。 The rod holder 130 is restricted from moving in the sliding direction of the plate by the guide action of the two vertical guides 125 (the vertical surface 125a and the guide rail 125b) and is perpendicular to the sliding direction of the plate. It is possible to move. This rod holder 130 has a second through-hole 132 continuing from the cylindrical body 131 through which the extraction rod 170 passes, and is directed toward the fixed metal frame side of the rod holder 130 in a direction perpendicular to the sliding direction of the plate. An inclined surface 133 is provided as the inclined second sliding portion. Further, the two side surfaces 134 perpendicular to the sliding direction of the plate of the rod holder 130 are sliding surfaces (sliding portions) that can be brought into sliding contact with the vertical surface 125a of the vertical guide 125, respectively. A groove 135 for guiding (guiding) the guide rail 125b of the guide 125 is provided.
　コッター１４０は、プレートの摺動方向とは垂直な基板１４１からスライディングノズル装置の駆動装置である油圧シリンダー４５０方向に延びる連結部１４２を有しており、この連結部１４２の先端の凹部１４３によって油圧シリンダー４５０に着脱可能である。また、基板１４１から連結部１４２とは反対方向に２つの平行板１４４が延びている。この２つの平行板１４４は、引き抜いた上ノズル３００が入るための間隔、さらに本実施例では架台１２０の側壁１２２が入る間隔をもって平行に配置されている。この平行板１４４の固定金枠４１０側の面は、第１の摺動部１２４（摺動面）と摺動接触する第３の摺動部としての摺動面１４５となっており、固定金枠４１０と反対側の面はロッドホルダー１３０の第２の摺動部としての傾斜面１３３と摺動接触する第４の摺動部としての傾斜面１４６となっている。 The cotter 140 has a connecting portion 142 extending from a substrate 141 perpendicular to the sliding direction of the plate in a direction of a hydraulic cylinder 450 that is a driving device of the sliding nozzle device. The cylinder 450 is detachable. Two parallel plates 144 extend from the substrate 141 in the direction opposite to the connecting portion 142. The two parallel plates 144 are arranged in parallel with an interval for the extracted upper nozzle 300 to enter, and in this embodiment, an interval for the side wall 122 of the gantry 120 to enter. The surface of the parallel plate 144 on the fixed metal frame 410 side is a sliding surface 145 as a third sliding portion that is in sliding contact with the first sliding portion 124 (sliding surface). The surface opposite to the frame 410 is an inclined surface 146 as a fourth sliding portion that is in sliding contact with the inclined surface 133 as the second sliding portion of the rod holder 130.
　引抜ロッド１５０は、図３及び図４に表れているように、そのロッド本体１５１の先端部に上ノズル３００と係合可能な係合部としてノズル係り部１５２を有し、中間部にストッパーとしてのハンドル１５３を有する。このハンドル１５３はロッド本体１５１に螺合しており、ハンドル１５３を回転することでハンドル１５３のロッド本体１５１長手方向の位置を変えることができる。 As shown in FIGS. 3 and 4, the drawing rod 150 has a nozzle engaging portion 152 as an engaging portion engageable with the upper nozzle 300 at the distal end portion of the rod main body 151, and as a stopper at the intermediate portion. The handle 153 is provided. The handle 153 is screwed into the rod main body 151, and the position of the handle 153 in the longitudinal direction of the rod main body 151 can be changed by rotating the handle 153.
　なお、ノズル係り部１５１は、図８で説明した特許文献１の変位部材１１と同様の構成であり、その他、公知のものを使用することができる。 In addition, the nozzle engaging part 151 has the same configuration as the displacement member 11 of Patent Document 1 described in FIG. 8, and other known ones can be used.
　次に、上ノズル３００を引き抜く手順について説明する。 Next, the procedure for pulling out the upper nozzle 300 will be described.

At the same time, the connecting portion 142 of the cotter 140 is connected to the hydraulic cylinder 450. Then, the extraction rod 150 is inserted into the nozzle hole 310 of the upper nozzle 300 from the second through hole 132 of the rod holder 130 through the opening of the fixed metal frame 410, and the nozzle engaging portion 152 is connected to the base end portion of the upper nozzle 300. Engage. Further, the handle 153 of the extraction rod 150 is rotated, and the handle 153 is moved to the upper nozzle 300 side until the handle 153 cannot be rotated, and is brought into contact with the cylindrical body 131 of the rod holder 130. In this state, the cotter 140 is moved to the hydraulic cylinder 450 side by the hydraulic cylinder 450 of the sliding nozzle device. Then, the rod holder 130 slides in the direction opposite to the upper nozzle 9 (plate) by the sliding of the inclined surface 133 as the second sliding portion of the rod holder 130 and the inclined surface 146 as the fourth sliding portion of the cotter 140. In a direction perpendicular to the sliding direction). As a result, the extraction rod 150 is pulled through the handle 153, and the upper nozzle 300 is extracted.
　なお、本実施例では、ロッドホルダー１３０の第２の摺動部及びコッター１４０の第４の摺動部の組をプレートの摺動方向に対して垂直な方向に向けて傾斜する傾斜面としたが、架台１２０の第１の摺動部１２４及びコッター１４０の第３の摺動部（摺動面１４５）の組をプレートの摺動方向に対して垂直な方向に向けて傾斜する傾斜面としてもよいし、両方の組を傾斜面としてもよい。 In this embodiment, the set of the second sliding portion of the rod holder 130 and the fourth sliding portion of the cotter 140 is an inclined surface that is inclined in a direction perpendicular to the sliding direction of the plate. However, the set of the first sliding portion 124 of the gantry 120 and the third sliding portion (sliding surface 145) of the cotter 140 is an inclined surface that is inclined in a direction perpendicular to the sliding direction of the plate. Alternatively, both sets may be inclined surfaces.

FIG. 6 is a perspective view showing an upper nozzle pulling-out device according to a second embodiment of the present invention, and FIG. 7 is an enlarged front view of the main part of FIG.
　本実施例は、第１実施例において、ロッドホルダー１３０の第２の摺動部を傾斜配置されたローラー１３６とし、コッター１４０の第３の摺動部をローラー１４７とした例である。さらに本実施例では、ロッドホルダー１３０の側面１３４に垂直板１２５の垂直面１２５ａに摺動接触する摺動部としてローラー１３７を設けている。本実施例においても第１実施例と同様の作用効果を奏する。 This embodiment is an example in which, in the first embodiment, the second sliding portion of the rod holder 130 is an inclined roller 136, and the third sliding portion of the cotter 140 is a roller 147. Furthermore, in this embodiment, a roller 137 is provided on the side surface 134 of the rod holder 130 as a sliding portion that comes into sliding contact with the vertical surface 125 a of the vertical plate 125. In this embodiment, the same effect as that of the first embodiment is obtained.
　なお、ロッドホルダー１３０の第２の摺動部と、コッター１４０の第３の摺動部のいずれか一方のみをローラーとしてもよい。 Note that only one of the second sliding portion of the rod holder 130 and the third sliding portion of the cotter 140 may be a roller.
