Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure for molten iron tilting trough such that the tilting trough can be taken out without depending on the technique of a crane-worker and without breaking this trough. <P>SOLUTION: Even in the case that two molten iron tapping troughs 2 are oppositely arranged above the tilting trough 1, when adjusting the pouring-down position of the molten iron from the molten iron tapping troughs 2, the position of the tilting trough 1 is shifted to the longitudinal direction of the molten iron tapping troughs 2 together with an upper part cart 8 by shifting the wheels 9 for upper part cart along short-length rails 11 of a lower part cart 12. Further, when taking out the tilting trough 1, the position of the tilting trough 1 together with the lower part car can be shifted in the direction orthogonal to the longitudinal direction of the molten iron tapping trough by shifting the wheels of the lower part cart along rails on floor. Thus, the tilting trough 1 can be lifted up above without interfering with the molten iron tapping troughs 2. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、高炉から出銑した溶銑を輸送車両に注入する溶銑傾注樋構造に関し、特に傾注樋の交換作業を容易にするのに好適なものである。   The present invention relates to a hot metal tilting iron structure for injecting hot metal discharged from a blast furnace into a transport vehicle, and is particularly suitable for facilitating exchanging work of the tilting iron.

高炉から出銑した溶銑は、出銑樋から溶銑樋先金枠を通って傾注樋に注ぎ落とされ、この傾注樋を傾動してトピードカーと呼ばれる輸送車両に注入される。傾注樋の交換や修理などで傾注樋を取り外す際、傾注樋をそのまま持ち上げると溶銑樋先金枠と干渉してしまう。そこで、従来は溶銑樋先金枠を取り外して傾注樋をクレーンで持ち上げていたが、溶銑樋先金枠の脱着工程が複雑なため、本来、溶銑樋先金枠からの注ぎ落とし位置を調整するための傾注樋台車のレールを出銑樋の長手方向に延長し、傾注樋を台車ごと出銑樋の長手方向先方に移動し、溶銑樋先金枠をかわせる位置で傾注樋をクレーンで持ち上げるようにした。   The hot metal discharged from the blast furnace is poured into the tilting iron through the hot metal frame from the hot metal, and this tilting iron is tilted and injected into a transport vehicle called a topped car. When removing the tilting rod for exchanging or repairing the tilting rod, if the tilting rod is lifted as it is, it will interfere with the hot metal frame. So, conventionally, the hot metal tip frame was removed and the tilted iron was lifted with a crane. However, since the process of detaching the hot metal tip frame is complicated, the pouring position from the hot metal tip frame should be adjusted. For this purpose, the rail of the tilting trolley is extended in the longitudinal direction of the output, and the tilting rod is moved to the longitudinal direction of the output together with the trolley, and the tilting rod is lifted with a crane at a position where the hot metal frame is displaced. I made it.

しかしながら、近年、前記輸送車両への注入ピット（受銑ピットともいう）を増やさないために１つの傾注樋に２つの出銑樋から溶銑を注ぎ込むようにレイアウトすることが多い。このような場合、２つの出銑樋は互いに対向する位置に配設されているので、何れか一方の出銑樋の長手方向先方に台車ごと傾注樋を移動しても、他方の出銑樋の下方になってしまうので、そのまま傾注樋を上方に持ち上げることができない。そのため、下記特許文献１では、傾注樋をクレーンで少し持ち上げ、そのまま出銑樋などと干渉しない位置まで水平に移動し、その場所で上方に持ち上げるようにしている。   However, in recent years, in order not to increase the number of injection pits (also referred to as receiving pits) to the transport vehicle, the layout is often such that hot metal is poured into two tilted irons in one inclined pouring rod. In such a case, since the two outputs are arranged at positions facing each other, even if the tilting rod is moved together with the carriage toward the longitudinal direction of one of the outputs, the other output is Therefore, the tilting rod cannot be lifted up as it is. Therefore, in the following Patent Document 1, the tilting rod is slightly lifted with a crane, is moved horizontally to a position where it does not interfere with the tread and the like, and is lifted upward at that location.

しかしながら、傾注樋を少し持ち上げ、そのまま出銑樋などと干渉しない位置まで水平に移動するのはクレーン作業者の技術に依存し、また構造物と接触して破損する恐れもある。
本発明は、上記のような問題点に着目してなされたものであり、クレーン作業者の技術に依存することなく、傾注樋を破損することなく取り外すことが可能な溶銑傾注樋構造を提供することを目的とするものである。 However, it is dependent on the skill of the crane operator to lift the tilting rod slightly and move it horizontally to a position where it does not interfere with the output, etc., and there is a risk of damage due to contact with the structure.
The present invention has been made paying attention to the above-described problems, and provides a hot metal tilting rod structure that can be removed without damaging the tilting rod without depending on the technique of the crane operator. It is for the purpose.

上記課題を解決するために、本発明の溶銑傾注樋構造は、高炉から出銑した溶銑を輸送車両に注入する傾注樋と、前記傾注樋の上方で互いに対向配置された２本の出銑樋及び溶銑樋先金枠と、前記傾注樋を傾動可能に支持し且つ前記出銑樋の長手方向に移動可能な車輪を備えた上部台車と、前記上部台車の車輪が出銑樋の長手方向に移動するための短寸のレールを備え且つ前記出銑樋の長手方向と直交方向に移動可能な車輪を備えた下部台車と、前記下部台車の車輪が出銑樋の長手方向と直交方向に移動するために前記輸送車両上方の床面に設けられた長寸の床上レールとを備えたことを特徴とするものである。   In order to solve the above-mentioned problem, the hot metal tilting iron structure of the present invention includes a tilting iron for injecting hot metal discharged from a blast furnace into a transport vehicle, and two hot irons arranged opposite to each other above the tilting iron. And an upper carriage provided with a hot metal tip frame, a wheel that supports the tilting rod in a tiltable manner and is movable in the longitudinal direction of the tapping bar, and a wheel of the upper carriage in the longitudinal direction of the tapping bar A lower carriage provided with a short rail for moving and a wheel movable in a direction orthogonal to the longitudinal direction of the output, and a wheel of the lower carriage moved in a direction orthogonal to the longitudinal direction of the output In order to do so, a long rail on the floor provided on the floor above the transport vehicle is provided.

また、前記上部台車の車輪を駆動するための上部台車移動用モータを当該上部台車上に搭載し、前記下部台車の車輪を駆動するための下部台車移動用モータを当該下部台車上に搭載したことを特徴とするものである。
また、前記上部台車を移動するための上部台車移動用油圧シリンダを前記下部台車上に設置し、前記下部台車を移動するための下部台車移動用油圧シリンダを前記輸送車両上方の床面上に設置したことを特徴とするものである。 In addition, an upper cart moving motor for driving the wheels of the upper cart is mounted on the upper cart, and a lower cart moving motor for driving the wheels of the lower cart is mounted on the lower cart. It is characterized by.
Also, an upper carriage moving hydraulic cylinder for moving the upper carriage is installed on the lower carriage, and a lower carriage moving hydraulic cylinder for moving the lower carriage is installed on the floor above the transport vehicle. It is characterized by that.

而して、本発明の溶銑傾注樋構造によれば、出銑樋からの溶銑の注ぎ落とし位置を調整する場合には下部台車の短寸のレールに沿って上部台車の車輪を移動させることで当該上部台車ごと傾注樋の位置を出銑樋の長手方向に移動し、傾注樋を取り外す場合には床上レールに沿って下部台車の車輪を移動させることで当該下部台車ごと傾注樋の位置を出銑樋の長手方向と直交方向に移動することができ、これにより出銑樋に干渉することなく傾注樋を上方に持ち上げることができるので、クレーン作業者の技術に依存することなく、傾注樋を破損することなく取り外すことができる。   Thus, according to the hot metal tilting and pouring structure of the present invention, when adjusting the pouring position of the hot metal from the tap iron, the wheel of the upper carriage is moved along the short rail of the lower carriage. Move the position of the tilting anchor for each upper carriage in the longitudinal direction of the output, and when removing the tilting anchor, move the wheel of the lower carriage along the rail on the floor to move the position of the tilting anchor for each lower carriage. Since it can move in the direction perpendicular to the longitudinal direction of the rod, this makes it possible to lift the tilting rod upward without interfering with the output, so that the tilting rod is not dependent on the skill of the crane operator. Can be removed without damage.

また、上部台車の車輪を駆動するための上部台車移動用モータを当該上部台車上に搭載し、下部台車の車輪を駆動するための下部台車移動用モータを当該下部台車上に搭載したことにより、上部台車及び下部台車の単独での移動が可能となり、傾注樋の位置調整や取り外しがより一層容易になる。
また、上部台車を移動するための上部台車移動用油圧シリンダを下部台車上に設置し、下部台車を移動するための下部台車移動用油圧シリンダを輸送車両上方の床面上に設置したことにより、上部台車及び下部台車の移動システムが簡潔になる。 In addition, by mounting an upper carriage moving motor for driving the wheels of the upper carriage on the upper carriage, and mounting a lower carriage movement motor for driving the wheels of the lower carriage on the lower carriage, The upper carriage and the lower carriage can be moved independently, and the position adjustment and removal of the tilting rod are further facilitated.
In addition, by installing an upper carriage moving hydraulic cylinder for moving the upper carriage on the lower carriage, and installing a lower carriage moving hydraulic cylinder for moving the lower carriage on the floor above the transport vehicle, The movement system of the upper and lower carts is simplified.

次に、本発明の溶銑傾注樋構造の一実施形態について図面を参照しながら説明する。
図１〜図３は、本実施形態の溶銑傾注樋構造の全体図であり、図１は正面図、図２は側面図、図３は平面図である。図中の符号１は傾注樋、符号２は出銑樋である。出銑樋２の下端部には溶銑樋先金枠３が取付けられている。図示内高炉から出銑した溶銑は、出銑樋２から溶銑樋先金枠３を通って傾注樋１に注ぎ落とされる。傾注樋１は支持枠４に支持され、この支持枠４をモータ５で回転することにより、例えば図２の時計回り方向、反時計回り方向の何れにも傾動することができる。従って、図２のように傾注樋１を時計回り方向又は反時計回り方向に傾動することで、２台のトピードカー６の何れにも溶銑を注入することができる。なお、本実施形態では、２本の出銑樋２が、傾注樋１の上方で対向配設され、例えば夫々の出銑樋２から交互に溶銑を傾注樋１に注ぎ落とすように構成されている。その結果、傾注樋１を取り外す場合に、そのまま上方に持ち上げたのでは、出銑樋２の溶銑樋先金枠３と干渉してしまう。また、トピードカー６の上方で、且つ傾注樋１が配設されている上部床２０には、溶銑が通過する開口部２１が開設されている。 Next, an embodiment of the hot metal tilting structure of the present invention will be described with reference to the drawings.
1 to 3 are general views of the hot metal tilting and pouring structure of the present embodiment, FIG. 1 is a front view, FIG. 2 is a side view, and FIG. 3 is a plan view. In the figure, reference numeral 1 is a tilting anchor and reference numeral 2 is an output. A hot metal tip frame 3 is attached to the lower end of the tapping iron 2. The hot metal discharged from the illustrated blast furnace is poured from the hot metal 2 through the hot metal tip frame 3 to the tilting iron 1. The tilting rod 1 is supported by a support frame 4 and can be tilted in, for example, a clockwise direction or a counterclockwise direction in FIG. 2 by rotating the support frame 4 with a motor 5. Therefore, the hot metal can be poured into either of the two topped cars 6 by tilting the tilting rod 1 in the clockwise direction or the counterclockwise direction as shown in FIG. In the present embodiment, the two tapping rods 2 are arranged to face each other above the tilting rod 1 and, for example, the molten iron is alternately poured onto the tilting rod 1 from each tapping rod 2. Yes. As a result, when the tilting rod 1 is removed, if it is lifted upward as it is, it will interfere with the hot metal tip frame 3 of the spout 2. In addition, an opening 21 through which the hot metal passes is formed in the upper floor 20 where the inclined pouring rod 1 is disposed above the topped car 6.

前記支持枠４の回転軸を支持する軸受７やモータ５は上部台車８に搭載されている。上部台車８は、傾注樋１を傾動したときに溶銑がかからないよう、傾注樋１の傾動方向、即ち出銑樋２の長手方向と直交方向には短く、出銑樋２の長手方向に長い車体に形成されている。なお、上部台車８の車体長手方向中央部は、傾注樋１の傾動を阻害しないように、少し窪んでいる。また、上部台車８の車体の四隅には上部台車用車輪９が回転自在に取付けられている。これらの上部台車用車輪９は、後述する下部台車１２上に敷設された短尺レール１１に搭載され、出銑樋２の長手方向に移動可能としてある。また、４つの上部台車用車輪９のうちの１つはアクチュエータである上部台車移動用モータ１０によって回転駆動される。   A bearing 7 and a motor 5 that support the rotating shaft of the support frame 4 are mounted on an upper carriage 8. The upper carriage 8 is a vehicle body that is short in the tilting direction of the tilting rod 1, that is, in the direction perpendicular to the longitudinal direction of the output 2 and long in the longitudinal direction of the output 2 so that the molten iron is not applied when the tilting rod 1 is tilted. Is formed. Note that the central portion of the upper carriage 8 in the longitudinal direction of the vehicle body is slightly recessed so as not to inhibit the tilting rod 1 from tilting. Further, upper truck wheels 9 are rotatably attached to the four corners of the body of the upper truck 8. These upper cart wheels 9 are mounted on a short rail 11 laid on a lower cart 12 described later, and are movable in the longitudinal direction of the output 2. One of the four upper cart wheels 9 is rotationally driven by an upper cart moving motor 10 as an actuator.

前述したように、上部台車８は下部台車１２上の短尺レール１１に搭載され、当該短尺レール１１の敷設方向、即ち出銑樋２の長手方向に移動可能である。ちなみに、この短尺レール１１に沿った上部台車８の移動は、出銑樋２及び溶銑樋先金枠３から傾注樋１に注ぎ落とされる溶銑の位置を調整するためのものであるから、短尺レール１１は短尺でよい。一方、下部台車１２も、傾注樋１を傾動したときに溶銑がかからないよう、傾注樋１の傾動方向、即ち出銑樋２の長手方向と直交方向には短く、出銑樋２の長手方向に長い車体に形成されている。また、下部台車１２の車体の一部は、上部床２０の開口部２１に合わせて切欠きが設けられている。   As described above, the upper carriage 8 is mounted on the short rail 11 on the lower carriage 12 and is movable in the laying direction of the short rail 11, that is, in the longitudinal direction of the output 2. Incidentally, since the movement of the upper carriage 8 along the short rail 11 is for adjusting the position of the hot metal poured from the hot metal 2 and the hot metal tip frame 3 to the tilting iron 1, the short rail is used. 11 may be short. On the other hand, the lower carriage 12 is also short in the tilting direction of the tilting rod 1, that is, in the direction perpendicular to the longitudinal direction of the barb 2, so that the molten iron is not applied when the tilting bar 1 is tilted. It is formed on a long car body. In addition, a part of the vehicle body of the lower carriage 12 is provided with a notch in accordance with the opening 21 of the upper floor 20.

そして、下部台車１２の車体の四隅には下部台車用車輪１３が回転自在に取付けられている。これらの下部台車用車輪１３は、上部床２０上に敷設された床上レール１５に搭載され、出銑樋２の長手方向と直交方向に移動可能としてある。また、４つの下部台車用車輪１３のうちの１つはアクチュエータである下部台車移動用モータ１４によって回転駆動される。従って、下部台車１２は、上部台車８や傾注樋１ごと、床上レール１５に沿って出銑樋２の長手方向と直交方向に移動することができるので、傾注樋１を取り外す場合には、例えば図２の二点鎖線の位置まで下部台車１２を移動させると、傾注樋１の上方に障害物がなくなるので、傾注樋１をクレーンなどでまっすぐ上方に持ち上げることができる。   And the lower cart wheel 13 is rotatably attached to the four corners of the vehicle body of the lower cart 12. These lower cart wheels 13 are mounted on a floor rail 15 laid on the upper floor 20 and are movable in a direction perpendicular to the longitudinal direction of the output 2. One of the four lower cart wheels 13 is rotationally driven by a lower cart moving motor 14 as an actuator. Therefore, the lower carriage 12 can move in the direction perpendicular to the longitudinal direction of the output 2 along the floor rail 15 together with the upper carriage 8 and the tilting rod 1, so when removing the tilting rod 1, for example, When the lower carriage 12 is moved to the position of the two-dot chain line in FIG. 2, no obstacles are left above the tilting rod 1, so that the tilting rod 1 can be lifted straight up with a crane or the like.

このように、本実施形態の溶銑傾注樋構造では、出銑樋２からの溶銑の注ぎ落とし位置を調整する場合には下部台車１２の短寸レール１１に沿って上部台車用車輪９を移動させることで上部台車８ごと傾注樋１の位置を出銑樋２の長手方向に移動し、傾注樋１を取り外す場合には床上レールに沿って下部台車の車輪を移動させることで当該下部台車ごと傾注樋１の位置を出銑樋２の長手方向と直交方向に移動することができ、これにより出銑樋２に干渉することなく傾注樋１を上方に持ち上げることができるので、クレーン作業者の技術に依存することなく、傾注樋１を破損することなく取り外すことができる。   As described above, in the hot metal tilt pouring structure of the present embodiment, the upper cart wheel 9 is moved along the short rail 11 of the lower cart 12 when adjusting the pouring position of the hot metal from the output 2. In this way, the position of the tilting rod 1 is moved in the longitudinal direction of the output 2 together with the upper cart 8, and when the tilting rod 1 is removed, the wheel of the lower cart is moved along the floor rail. The position of the rod 1 can be moved in a direction perpendicular to the longitudinal direction of the barb 2, and the tilted rod 1 can be lifted upward without interfering with the barb 2, so that the technique of the crane operator The decanting rod 1 can be removed without damaging it.

また、上部台車８の上部台車用車輪９を駆動するための上部台車移動用モータ１０を当該上部台車８上に搭載し、下部台車１２の下部台車用車輪１３を駆動するための下部台車移動用モータ１４を当該下部台車１２上に搭載したことにより、上部台車８及び下部台車１３の単独での移動が可能となり、傾注樋１の位置調整や取り外しがより一層容易になる。   Further, an upper carriage moving motor 10 for driving the upper carriage wheel 9 of the upper carriage 8 is mounted on the upper carriage 8 and the lower carriage movement for driving the lower carriage wheel 13 of the lower carriage 12 is performed. By mounting the motor 14 on the lower carriage 12, the upper carriage 8 and the lower carriage 13 can be moved independently, and the position adjustment and removal of the tilting rod 1 are further facilitated.

図４には、本発明の溶銑傾注樋構造の他の実施形態を示す。図４に示す溶銑傾注樋構造は、前記第１実施形態の溶銑傾注樋構造に類似しており、同等の構成には同等の符号を附して詳細な説明を省略する。この実施形態では、前記上部台車８を移動するための上部台車移動用モータや下部台車１２を移動するための下部台車移動用モータが除去され、代わりに上部台車移動用油圧シリンダ２２及び下部台車移動用油圧シリンダ２３が設けられている。このうち上部台車移動用油圧シリンダ２２は、シリンダチューブが下部台車１２に取付けられ、ピストンロッドが上部台車８に連結されている。また、下部台車移動用油圧シリンダ２３は、シリンダチューブが上部床に取付けられ、ピストンロッドが下部台車１２に連結されている。   FIG. 4 shows another embodiment of the hot metal tilting pouring structure of the present invention. The hot metal decanting structure shown in FIG. 4 is similar to the hot metal decanting structure of the first embodiment, and the same components are denoted by the same reference numerals and detailed description thereof is omitted. In this embodiment, the upper carriage moving motor for moving the upper carriage 8 and the lower carriage moving motor for moving the lower carriage 12 are removed, and instead the upper carriage moving hydraulic cylinder 22 and the lower carriage movement are removed. A hydraulic cylinder 23 is provided. Among them, the upper carriage moving hydraulic cylinder 22 has a cylinder tube attached to the lower carriage 12 and a piston rod connected to the upper carriage 8. The lower bogie moving hydraulic cylinder 23 has a cylinder tube attached to the upper floor and a piston rod connected to the lower bogie 12.

このため、上部台車移動用油圧シリンダ２２を伸縮すれば、短尺レール１１に沿って上部台車８が移動し、下部台車移動用油圧シリンダ２３を伸縮すれば、床上レール１５に沿って下部台車１２が移動する。油圧シリンダによる移動システムは、モータ駆動による移動システムに比べて構成が簡潔である。そのため、本実施形態では、上部台車８及び下部台車１２の移動システムを簡潔にすることができる。   Therefore, if the upper carriage moving hydraulic cylinder 22 is expanded and contracted, the upper carriage 8 moves along the short rail 11, and if the lower carriage moving hydraulic cylinder 23 is expanded and contracted, the lower carriage 12 is moved along the floor rail 15. Moving. The movement system using a hydraulic cylinder has a simpler configuration than the movement system using a motor. Therefore, in this embodiment, the movement system of the upper trolley 8 and the lower trolley 12 can be simplified.
