Description
本発明は、コークス炉の装炭車の車止め構造に関する。 The present invention relates to a stop structure for a coal-cooked car of a coke oven.
コークス炉は、石炭を乾留する炭化室と、炭化室へ熱を供給するために燃料を燃焼する燃焼室と、燃焼室からの燃焼排ガスと燃料ガス、あるいは燃焼用空気との熱交換を行う蓄熱室との主として3つの部分から構成されている。そして、コークス炉は、燃焼室と炭化室が連接して設置されて一つの窯を構成し、この窯が炉団方向に複数(たとえば50窯)集まって炉団を形成している。 A coke oven is a carbon storage chamber for carbonizing coal, a combustion chamber for burning fuel to supply heat to the carbonization chamber, and a heat storage for exchanging heat between combustion exhaust gas and fuel gas from the combustion chamber or combustion air. The chamber is mainly composed of three parts. In the coke oven, a combustion chamber and a carbonization chamber are connected to each other to form one kiln, and a plurality of kilns (for example, 50 kilns) are gathered in the direction of the kiln to form a kiln.
この複数の炉団1は、たとえば、図1に示したように、装炭前の石炭(乾留前の石炭)を一時的に蓄える石炭塔2の両側に形成するなどして、複数の炉団1で一つの石炭塔2を共用している。 For example, as shown in FIG. 1, the plurality of furnace groups 1 are formed on both sides of a coal tower 2 for temporarily storing coal before coal loading (coal before carbonization). 1 shares one coal tower 2.
石炭塔2内の上方には、炭槽3が設けられ、炭槽3より、石炭塔2下に待機する装炭車4の装入ホッパーに乾留前の石炭を積載する。石炭を装入ホッパーに充填した装炭車4は、コークス炉の炉頂に敷設した軌条5を走行し、各炉団1の所定の炭化室14に停車し上方から炭化室14へ石炭を装入する。そして、装炭車4から炭化室14に装入された石炭は、燃焼室15の熱で加熱されることにより乾留されてコークス化する。 Above the inside of the coal tower 2, a coal tank 3 is provided, and the coal before dry distillation is loaded from the coal tank 3 onto the charging hopper of the coal-coating vehicle 4 waiting under the coal tower 2. The coal loading vehicle 4 filled with coal in the charging hopper travels on the rail 5 laid on the top of the coke oven, stops at a predetermined carbonization chamber 14 of each furnace group 1 and charges the coal into the carbonization chamber 14 from above. To do. And the coal charged into the carbonization chamber 14 from the coal loading vehicle 4 is dry-distilled by being heated by the heat of the combustion chamber 15 to be coke.
コークス炉の終端部には頑丈なデッキ6が設けられ、軌条5は、この終端部まで敷設されている。このデッキ6上の終端部では、軌条5からの脱線と、装炭車4の転落を防止する車体ストッパー7を設けた車止め構造となっている(たとえば、特許文献1等参照)。 A sturdy deck 6 is provided at the end of the coke oven, and the rail 5 is laid to this end. In the terminal part on this deck 6, it has a vehicle stop structure which provided the vehicle body stopper 7 which prevents derailment from the rail 5 and fall of the charcoal vehicle 4 (for example, refer patent document 1 etc.).
ところで、コークス炉を20年〜30年を越える期間で稼働して石炭乾留、コークス排出を繰り返すと、炭化室14や燃焼室15を形成している煉瓦が劣化し、崩壊してくる。このため、劣化した煉瓦壁などを撤去し、新たなコークス炉を立設する更新工事が行われる。この更新工事は、石炭塔2の両側すべての炉団1を同時に解体、更新する方法もあるが、一般的には生産減(コークス、ガス、化成品等)影響を最小限にするため、炉団単位で実施することが多い。 By the way, when the coke oven is operated for a period exceeding 20 to 30 years and the coal dry distillation and coke discharge are repeated, the bricks forming the carbonization chamber 14 and the combustion chamber 15 deteriorate and collapse. For this reason, renewal work is carried out to remove the deteriorated brick wall and set up a new coke oven. In this renewal work, there is a method of dismantling and renewing all the furnace groups 1 on both sides of the coal tower 2 at the same time. However, in general, in order to minimize the effects of reduced production (coke, gas, chemical products, etc.) Often conducted in groups.
たとえば、図2に示すように、二点鎖線で示した石炭塔2の解体側の炉団(第1番目の窯〜第50番目の窯まで。以降、解体側Aコークス炉という)を解体し、もう片側である稼働側の炉団(第51番目の窯〜第100番目の窯まで。以降、稼働側Bコークス炉という)は、稼働状態で残しておく。解体側Aコークス炉の更新工事が完了し、稼働が可能となったら、稼働側Bコークス炉の解体に取り掛かる。この際、石炭塔2は、更新せずに、そのまま利用する。このように石炭塔2の片側のコークス炉ごとに解体、更新することにより、コークス炉の更新工事中も高炉へのコークスの供給や所内へのCOG(コークス炉ガス)供給の低下を最低限に抑えた操業を継続できる。 For example, as shown in FIG. 2, the decommissioning side furnace group (from the first kiln to the 50th kiln, hereinafter referred to as the demolition side A coke oven) indicated by the two-dot chain line is demolished. The other side of the operating side furnace cluster (from the 51st kiln to the 100th kiln, hereinafter referred to as the operating side B coke oven) is left in the operating state. When the renewal work of the dismantling side A coke oven is completed and the operation becomes possible, the dismantling of the operating side B coke oven is started. At this time, the coal tower 2 is used as it is without being updated. In this way, by disassembling and renewing each coke oven on one side of the coal tower 2, during the renewal work of the coke oven, the supply of coke to the blast furnace and the decrease in COG (coke oven gas) supply to the site are minimized. We can continue the operation that we restrained.
このようなコークス炉の更新工事(パドアップ、再建設)では、石炭塔2から、解体側Aコークス炉へ、装炭車4が転落しないように安全対策として、たとえば、図2に示したような位置に、車体ストッパー7を設置することが必要となる。 In such a coke oven renewal construction (pad-up, reconstruction), as a safety measure, for example, the position shown in FIG. 2, so that the coal-mounted vehicle 4 does not fall from the coal tower 2 to the dismantling side A coke oven. In addition, it is necessary to install the vehicle body stopper 7.
この場合、車体ストッパー7は、石炭塔2内か、石炭塔2と解体側Aコークス炉の間の中間部80に設置することが必要となる。解体側Aコークス炉の工事に関わらず石炭塔2からの石炭供給は常に稼働状態にあるので、石炭塔2本体の工事は、最も工事時間の確保が難しい設備である。
また、車体ストッパー7を固定する場所が、石炭塔2に敷設した軌条5(石炭塔2の床面8)や中間部80は、車体ストッパー7を設置する構造になっていないので、重量200tを超える装炭車4の衝突エネルギーを全て受け止めるには強度(耐力)が不十分で、補強が必要になる。
In this case, it is necessary to install the vehicle body stopper 7 in the coal tower 2 or in an intermediate portion 80 between the coal tower 2 and the dismantling side A coke oven. Regardless of the construction of the demolition side A coke oven, the coal supply from the coal tower 2 is always in operation, so the construction of the coal tower 2 main body is the most difficult facility to secure the construction time.
Further, the rail 5 (floor surface 8 of the coal tower 2) and the intermediate portion 80 laid on the coal tower 2 are not structured to install the vehicle body stopper 7 at a place where the vehicle body stopper 7 is fixed. Strength (strength) is insufficient to receive all the collision energy of the coal-coating vehicle 4 exceeding, and reinforcement is required.
仮定として車体ストッパー7を、中間部80に取り付けた場合、この中間部80の真下は、炉体メンテナンス用の道工具機器類の格納空間に相当し、装炭車4の軌条5の基礎として他の場所と比較して脆弱な場所なので、補強無しの状態では、完全に装炭車4を止めることができない。 Assuming that the vehicle body stopper 7 is attached to the intermediate portion 80, the portion directly below the intermediate portion 80 corresponds to a storage space for road tool equipment for furnace body maintenance. Since the place is weaker than the place, the coal-equipped vehicle 4 cannot be completely stopped without reinforcement.
従って、石炭塔2の床面8や、中間部80の場所で車体ストッパー7にかかる衝撃エネルギーを受けるためには、地下室底盤コンクリートから炉頂部まで繋がる独立した柱による補強が必要となる。即ち、地下室、1FL(変更弁室レベル)、2FL(プラットホームレベル)、炉頂までの大掛かりな基礎補強工事が必要になる。当然、基礎補強工事に必要な工事期間を確保するには、更新工事前の月間定修日(コークスの生産を数時間停止するコークス炉のメンテナンス日)等を数ヶ月利用した長期計画を実施しなければならない。 Therefore, in order to receive impact energy applied to the vehicle body stopper 7 at the floor surface 8 of the coal tower 2 or at the intermediate portion 80, reinforcement by an independent column connected from the basement floor base concrete to the furnace top is required. In other words, large-scale foundation reinforcement work is required from the basement, 1FL (change valve chamber level), 2FL (platform level), and the top of the furnace. Naturally, in order to secure the construction period necessary for the foundation reinforcement work, a long-term plan using the monthly regular repair date (coke oven maintenance date for which coke production is stopped for several hours) before the renewal work, etc., has been implemented for several months. There must be.
検討を行ったところ、基礎補強工事を、コークス炉の通常操業中に行なわなければならず、石炭塔2へ装炭車4の通行頻度が高く連続した有効な工事時間が取れないため、実現性はかなり低く不可能に近いと思われる。
次に、コークスの減産を少なくする基礎補強工事方法として、月間定修日ごとに部分補強工事を行い、これを繰り返して比較的長い工事期間をかけて、基礎補強工事を完遂することが考えられる。しかしながら、更新工事開始予想時期から数ヶ月あるいは、一年以上前から計画的に基礎補強工事を実施しなければならず、工事費用が高くなる割には工事効率が悪く、工事品質も不十分な、課題の多い方法である。
As a result of the examination, the foundation reinforcement work must be performed during the normal operation of the coke oven, and the coal tower 4 has a high frequency of passage to the coal tower 2 and it is not possible to have a continuous effective construction time. It seems quite low and almost impossible.
Next, as a method of foundation reinforcement work that reduces coke production, partial reinforcement work is performed on a regular monthly basis, and this may be repeated to complete the foundation reinforcement work over a relatively long construction period. . However, the foundation reinforcement work must be carried out systematically for several months or more than a year from the expected start date of the renewal work, and the construction efficiency is poor and the construction quality is inadequate for the high construction cost. It is a method with many problems.
以上の結果、基礎補強工事を実施可能な時期は、更新工事開始後となる。その場合でも、解体側Aコークス炉はもちろん、稼働側Bコークス炉も基礎補強工事を終えて車体ストッパー7を取り付けるまでは石炭塔2が使用できないため、コークス炉の操業が停止する。コークス炉の操業を停止すると、エネルギー不足対策等、大きな生産・コスト影響が発生する。また、中間部80等の石炭塔2から外れた場所へ、車体ストッパー7を設置する場合は、基礎補強範囲がさらに広くなるので、工事期間としても相当長くなる。 As a result, the time when the foundation reinforcement work can be performed is after the start of the renewal work. Even in that case, the operation of the coke oven stops because the coal tower 2 cannot be used until the dismantling side A coke oven as well as the operation side B coke oven is finished with the foundation reinforcement work and the vehicle body stopper 7 is attached. If the coke oven is shut down, there will be a significant production / cost impact such as energy shortage countermeasures. In addition, when the vehicle body stopper 7 is installed at a location off the coal tower 2 such as the intermediate portion 80, the foundation reinforcement range is further widened, so that the construction period is considerably long.
長期にわたるコークス炉の操業休止、装炭車4の通行制限、および石炭塔2の使用制限等の予測できない制約は、コークス生産影響(減産)の原因となる。また、更新工事に先立って、基礎補強工事を行うこととコークス生産を両立させるため、コークス炉の稼働、停止を繰り返すことは、老朽化したコークス炉の更なる炉体悪化要因にもなる。 Unexpected restrictions such as long-term coke oven shutdown, coal car 4 traffic restrictions, and coal tower 2 usage restrictions cause coke production impact (reduction). Prior to the renewal work, repeating the operation and stoppage of the coke oven in order to achieve both basic reinforcement work and coke production will cause further deterioration of the old coke oven.
さらに、軌条5と軌条5の基礎で、装炭車4が停止する際の衝撃エネルギーを吸収しようとすると、車体ストッパー7を固定する部分は大型となる。石炭塔2の給炭位置(すでに設けられている炭槽3の数や配置)を変えないのであれば、大型化した車体ストッパー7を固定する部分は、石炭塔2内の解体側Aコークス炉側の給炭位置の外側か、解体側Aコークス炉側の石炭塔2の外に設けることになる。その場合、大型化した車体ストッパー7を固定する部分が、解体側Aにはみ出すので、解体側Aコークス炉の解体工事用のスペースが狭くなる。一方、工事用のスペースを広くする場合は、操業制約(給炭可能な炭槽3の減少)を許容しなければ、工事は成立しない。 Furthermore, if it is going to absorb the impact energy at the time of the charcoal vehicle 4 stopping by the rail 5 and the foundation of the rail 5, the part which fixes the vehicle body stopper 7 will become large. If the coal supply position of the coal tower 2 (the number and arrangement of the coal tanks 3 already provided) is not changed, the part for fixing the enlarged vehicle body stopper 7 is the dismantling side A coke oven in the coal tower 2. It is provided outside the coal supply position on the side or outside the coal tower 2 on the dismantling side A coke oven side. In that case, since the part which fixes the enlarged vehicle body stopper 7 protrudes to the demolition side A, the space for demolition work of the demolition side A coke oven becomes narrow. On the other hand, in the case where the space for construction is widened, construction is not achieved unless operation restrictions (reduction of coal tank 3 that can be fed with coal) are not allowed.
そもそも、車体ストッパー7は、更新工事期間中の仮設のものであり、更新工事が完了した時点では撤去しなければならない。解体側Aコークス炉の更新工事完了後、稼働側Bコークス炉の更新工事を引き続き実施する場合、解体側Aコークス炉の更新工事用に設置した車体ストッパー7の流用はできない。あらためて、稼働側Bコークス炉側に同様の車体ストッパー7を取り付けるための基礎補強工事が必要となる。このように、コークス炉の更新工事の際に、基礎補強工事を行って、車体ストッパー7を設置する車止め構造は、工事難易度、工事期間、工事費用が高い割には、不経済な設備である。
従って、工事期間、工事費用対効果の点からすると、コークス炉の更新工事の際に、仮設のものである車体ストッパー7を設置するための基礎補強工事は、省略することが望まれる。
In the first place, the vehicle body stopper 7 is a temporary one during the renewal work period, and must be removed when the renewal work is completed. When the renewal work for the operation side B coke oven is continued after the completion of the renewal work for the dismantling side A coke oven, the vehicle body stopper 7 installed for the renewal work for the dismantling side A coke oven cannot be used. Again, foundation reinforcement work for attaching the same vehicle body stopper 7 to the working side B coke oven side is required. As described above, when the coke oven is renewed, the car stopper structure in which the foundation reinforcement work is performed and the body stopper 7 is installed is an uneconomical facility for the construction difficulty, construction period, and construction cost. is there.
Therefore, from the viewpoint of the construction period and cost effectiveness, it is desirable to omit the foundation reinforcement work for installing the vehicle body stopper 7 which is a temporary one during the renewal work of the coke oven.
本発明は、コークス炉の更新工事中、基礎補強工事を施さないか、補強を最小限としても装炭車4を停止させるに十分な強度を有し、工事期間の短縮および工事費用を抑制でき、コークス炉生産減が回避され、老朽化したコークス炉の悪化を抑制でき、更新工事終了後には、容易に撤去できるコークス炉の装炭車の車止め構造を提供することを目的とする。 The present invention does not perform foundation reinforcement work during renewal work of the coke oven, or has sufficient strength to stop the coal-mounted vehicle 4 even if reinforcement is minimized, and can shorten the construction period and reduce construction costs, The purpose of the present invention is to provide a stop structure for a coke oven loaded with a coke oven that can prevent a decrease in coke oven production, suppress deterioration of an aging coke oven, and can be easily removed after renewal work.
本発明は、上記の課題を解決するものであり、その要旨とするところは、以下のとおりである。
(1)石炭塔を支える既存の複数の柱の間に、横梁を渡し、前記横梁を渡す複数の柱には、前記複数の柱において前記横梁の両端を支持する横梁受けを設け、前記横梁受けの端部に、前記横梁の水平移動を防止するブロックを設け、さらに前記横梁に車体ストッパーを設置することを特徴とするコークス炉の装炭車の車止め構造。
(2)前記横梁の下部と、前記石炭塔の床面に敷かれた敷板または軌条とを一体化する、支柱が設けられていることを特徴とする(1)に記載のコークス炉の装炭車の車止め構造。
This invention solves said subject and the place made into the summary is as follows.
(1) A transverse beam is passed between a plurality of existing pillars that support the coal tower, and a transverse beam support that supports both ends of the transverse beam in the plurality of pillars is provided on the plurality of pillars that pass the transverse beam. A stop structure for a coke oven charcoal vehicle, wherein a block for preventing horizontal movement of the horizontal beam is provided at an end of the horizontal beam, and a vehicle body stopper is further installed on the horizontal beam.
(2) A coke oven loaded coal car according to (1), wherein a column is provided to integrate a lower part of the horizontal beam and a floor plate or rail laid on the floor of the coal tower. Car stop structure.
本発明により、コークス炉の装炭車4の車止め構造は、十分な強度を有し、工事期間が短縮でき、工事費用が抑制でき、コークス炉生産減が回避され、老朽コークス炉の悪化を抑制することができる。また、コークス炉を更新した後は、簡単に撤去することができる。 According to the present invention, the structure for stopping the coke oven 4 in the coke oven has sufficient strength, the construction period can be shortened, the construction cost can be reduced, the reduction in coke oven production is avoided, and the deterioration of the old coke oven is suppressed. be able to. In addition, after the coke oven is updated, it can be easily removed.
図3(a)(b)に示したように、もともと、石炭塔2には、石炭塔2を構成させるための柱10(コンクリート製または鋼製)が複数設けられている。この柱10は、石炭塔2を支えるという目的上、コークス炉基礎底盤コンクリートの上に、十分な強度で建設されている。そのため、更なる基礎補強工事を施さずとも、車体ストッパー7を支える十分な強度を有していることが期待された。 As shown in FIGS. 3A and 3B, the coal tower 2 is originally provided with a plurality of columns 10 (made of concrete or steel) for constituting the coal tower 2. For the purpose of supporting the coal tower 2, the pillar 10 is constructed with sufficient strength on the coke oven foundation bottom concrete. Therefore, it was expected to have sufficient strength to support the vehicle body stopper 7 without performing further foundation reinforcement work.
そこで、装炭車4を停止させるに必要な衝撃に対し、柱10の間に横梁9を渡して、柱10に横梁9の両端を、ブロック12aを設けた横梁受け12により支持し、横梁9に車体ストッパー7を設置した構造について、強度計算を行った。なお、ブロック12aは、解体側Aへの横梁9の水平移動を防止する。この構造を図3(a)(b)に示した。計算の結果、この構造は、十分に装炭車4を停止させる衝突エネルギーに耐え得ることが明らかとなった。 Therefore, against the impact required to stop the charcoal vehicle 4, the cross beam 9 is passed between the columns 10, and both ends of the cross beam 9 are supported on the column 10 by the cross beam receiver 12 provided with the block 12 a. The strength calculation was performed on the structure in which the vehicle body stopper 7 was installed. The block 12a prevents the horizontal beam 9 from moving horizontally to the dismantling side A. This structure is shown in FIGS. 3 (a) and 3 (b). As a result of calculation, it has been clarified that this structure can sufficiently withstand the collision energy that stops the charcoal vehicle 4.
本発明では、車体ストッパー7を固定する部材に、石炭塔2をもともと支える、頑丈な柱10を利用することで、新たな基礎補強工事をほとんど施すことなく装炭車4の車止めを行う車体ストッパー7を設置することができる。柱10に横梁9を支持する横梁受け12と、横梁9の水平方向を固定する横梁受け12に設けたブロック12aにより、衝突の荷重の大部分を受け止めることができるので、軌条5等の基礎補強工事を行わないか、最小限とすることが可能になり、車体ストッパー7の設置のための工事期間の短縮が可能となる。 In the present invention, by using a sturdy column 10 that originally supports the coal tower 2 as a member for fixing the vehicle body stopper 7, the vehicle body stopper 7 that stops the coal-mounted vehicle 4 with almost no new foundation reinforcement work. Can be installed. Since most of the impact load can be received by the horizontal beam receiver 12 that supports the horizontal beam 9 on the column 10 and the block 12a provided on the horizontal beam receiver 12 that fixes the horizontal direction of the horizontal beam 9, basic reinforcement of the rail 5 and the like can be received. It becomes possible not to perform the construction or to minimize it, and the construction period for installing the vehicle body stopper 7 can be shortened.
本発明により、装炭車4の軌条5上だけに設置する車体ストッパー7を軌条5とその基礎で固定する構造に比べ、軌条5とその基礎(コンクリートを含む)を補強する基礎補強工事の負担が軽減され、固定方法が小規模、小型化される。
この結果、軌条5の基礎補強工事のためのコークス炉の長期にわたる操業休止や、装炭車4の通行制限、および石炭塔2の炭槽3の使用制限等の制約は大幅に緩和される。そのため、コークス生産影響(減産)の解消とともに炉団1の操業休止等が回避されるため、老朽化したコークス炉の炉体悪化要因も解消することが可能となる。
Compared to the structure in which the vehicle body stopper 7 installed only on the rail 5 of the charcoal vehicle 4 is fixed by the rail 5 and its foundation, the load of the foundation reinforcement work for reinforcing the rail 5 and its foundation (including concrete) can be reduced. It is reduced, and the fixing method is reduced in size and size.
As a result, the restrictions such as the long-term operation stop of the coke oven for the foundation reinforcement work of the rail 5, the passage restriction of the coal-coating vehicle 4, and the restriction of use of the coal tank 3 of the coal tower 2 are relieved greatly. For this reason, since the coke production influence (reduction) is eliminated and the operation stop of the furnace group 1 is avoided, it is also possible to eliminate the deterioration factor of the aging coke oven.
また、解体側Aコークス炉の工事が完了した後に撤去する際も、柱10に固定の横梁受け12に支持されている横梁9を撤去すればよいだけである。また、撤去した横梁9は解体側Aコークス炉の更新工事完了後、引き続き稼働側Bコークス炉の更新工事を実施する場合、流用が可能である。仮に、本発明を採用しない場合、車体ストッパー7を固定するために、柱10以外の基礎等を新たに打ち込む基礎補強工事を施すことになる。その場合、コークス炉の更新工事が終了し、車体ストッパー7を設けた車止め構造を撤去する際も、新たに打ち込んだ基礎杭等も撤去しなければならないので、長い工事期間と高い工事費用がかかる。 Further, when removing after the construction of the dismantling side A coke oven is completed, it is only necessary to remove the cross beam 9 supported by the cross beam receiver 12 fixed to the column 10. Further, the removed horizontal beam 9 can be diverted when the renewal construction of the operation side B coke oven is continued after the completion of the renewal construction of the dismantling side A coke oven. If the present invention is not adopted, a foundation reinforcement work is performed in which a foundation other than the pillar 10 is newly driven in order to fix the vehicle body stopper 7. In that case, the renewal work of the coke oven is completed, and when the car stopper structure with the body stopper 7 is removed, the newly-found foundation piles must be removed, which requires a long construction period and high construction costs. .
横梁9は、地上で一本の構造体に組立後に上架しても、分割可能な架構体のどちらでも良い。分割した場合、更新するコークス炉の操業休止直前の短い工事期間で設置が可能である。 The horizontal beam 9 may be either a structure that can be divided or a structure that can be split on the ground after being assembled on a single structure. When divided, it can be installed in a short construction period just before the suspension of operation of the coke oven to be renewed.
横梁9を設ける柱10は、解体側Aコークス炉に一番近い石炭塔2の柱10が好ましい。また、図3(a)(b)と、図3(a)のC−C断面を示した図4、図3(a)のD−D断面を示した図5(a)に示したように、横梁9は、横梁受け12を介して設ける。
図2の、×で示した炭槽3のように、横梁9、車体ストッパー7を最も解体側Aコークス炉に設けても、解体側Aコークス炉側の炭槽3は、使用できないケースがある。
The column 10 provided with the cross beam 9 is preferably the column 10 of the coal tower 2 closest to the dismantling side A coke oven. 3 (a) and 3 (b), FIG. 4 showing the CC cross section of FIG. 3 (a), and FIG. 5 (a) showing the DD cross section of FIG. 3 (a). In addition, the cross beam 9 is provided via a cross beam receiver 12.
As in the case of the coal tank 3 indicated by x in FIG. 2, there are cases in which the coal tank 3 on the dismantling side A coke oven side cannot be used even if the cross beam 9 and the vehicle body stopper 7 are provided in the most dismantling side A coke oven. .
具体的に図3〜6を参照し、一実施形態として各部の構成と、横梁9の設置手順を説明する。 With reference to FIGS. 3-6 specifically, the structure of each part and the installation procedure of the cross beam 9 are demonstrated as one Embodiment.
柱10に設ける横梁受け12は、図3、図4、図5(a)に示すように、横梁9の水平移動を防止するブロック12a、係止部12b、ブロック支持ブラケット12c、転倒防止用アングル12dと落下防止用アングル12eで構成されている。係止部12b、ブロック支持ブラケット12cは、横梁受け12の一部を構成している。そして、係止部12b、ブロック支持ブラケット12cは、横梁受け12のそれぞれ端部に設けられている。 As shown in FIGS. 3, 4, and 5 (a), the horizontal beam receiver 12 provided on the column 10 includes a block 12 a that prevents horizontal movement of the horizontal beam 9, a locking portion 12 b, a block support bracket 12 c, and a fall prevention angle. 12d and a fall prevention angle 12e. The locking portion 12b and the block support bracket 12c constitute a part of the transverse beam receiver 12. The locking portion 12b and the block support bracket 12c are provided at the end portions of the cross beam receiver 12, respectively.
横梁9の水平移動を防止するブロック12aは、横梁受け12から石炭塔2の内部方向につき出して形成された凸形状である。横梁9の水平移動を防止するブロック12aは、車体ストッパー7と横梁9から伝達される装炭車4の衝撃力を水平力として受ける機構を得るために、横梁9と分離するが、石炭塔2の柱10に固定した横梁受け12自体とは溶接することなどにより、衝撃力を受けるに十分な大きさと強度となるよう一体化する。 The block 12 a for preventing the horizontal movement of the horizontal beam 9 has a convex shape formed so as to protrude from the horizontal beam receiver 12 toward the inside of the coal tower 2. The block 12a for preventing the horizontal movement of the horizontal beam 9 is separated from the horizontal beam 9 in order to obtain a mechanism for receiving the impact force of the charcoal vehicle 4 transmitted from the vehicle body stopper 7 and the horizontal beam 9 as a horizontal force. The horizontal beam receiver 12 itself fixed to the column 10 is integrated with the horizontal beam receiver 12 so as to have a size and strength sufficient to receive an impact force by welding or the like.
係止部12bは、柱10の稼働側Bの面に密着し、横梁受け12が解体側Aに動くことを防止する。また、横梁受け12は、横梁9を支持する柱10の稼働側Bコークス炉の面に密着する係止部12bで固定され、装炭車4が車体ストッパー7に衝突した際は、横梁9の衝撃力を、横梁9の水平移動を防止するブロック12aで受けると同時に、係止部12bでも衝撃力を受け止める。 The locking portion 12b is in close contact with the surface on the operating side B of the column 10 and prevents the cross beam receiver 12 from moving to the dismantling side A. Further, the horizontal beam receiver 12 is fixed by a locking portion 12b that is in close contact with the surface of the working side B coke oven of the column 10 that supports the horizontal beam 9, and when the coal-mounted vehicle 4 collides with the vehicle body stopper 7, the impact of the horizontal beam 9 occurs. The force is received by the block 12a that prevents the horizontal beam 9 from moving horizontally, and at the same time, the impact force is received by the locking portion 12b.
ブロック支持ブラケット12cは、装炭車4が車体ストッパー7に衝突した際に横梁9の衝撃力で横梁9の水平移動を防止するブロック12aが外に開いて横梁9が外れないようにするための役割である。ブロック支持ブラケット12cは柱10の解体側Aの面に密着して設置が可能であれば、柱10と固定をしなくても、機能は同じである。 The block support bracket 12c serves to prevent the horizontal beam 9 from being released by opening the block 12a that prevents horizontal movement of the horizontal beam 9 by the impact force of the horizontal beam 9 when the coal-coated vehicle 4 collides with the vehicle body stopper 7. It is. If the block support bracket 12c can be installed in close contact with the dismantling side A surface of the pillar 10, the function is the same even if it is not fixed to the pillar 10.
転倒防止用アングル12dと落下防止用アングル12eは、横梁受け12から石炭塔2の内部方向につき出して設けられており、横梁9の設置を容易にする。横梁9の水平移動を防止する12aによって、横梁9の解体側A面が支持されるが、横梁9の残りの3面のうち、転倒防止用アングル12dと落下防止用アングル12eにガイドされることによって、横梁9の上面以外の残りの2面の配置が決定できる。その結果、横梁9を上面以外の3面で支持することができる。 The fall prevention angle 12d and the fall prevention angle 12e are provided so as to protrude from the transverse beam receiver 12 toward the inside of the coal tower 2 and facilitate installation of the transverse beam 9. The dismantling side A surface of the horizontal beam 9 is supported by the horizontal beam 12a that prevents the horizontal beam 9 from moving horizontally, but the remaining three surfaces of the horizontal beam 9 are guided by the fall prevention angle 12d and the fall prevention angle 12e. Thus, the arrangement of the remaining two surfaces other than the upper surface of the cross beam 9 can be determined. As a result, the cross beam 9 can be supported by three surfaces other than the upper surface.
横梁9を柱10に設置するには、最初に柱10に、横梁受け12を設ける(図4(a))。この際、横梁受け12の据付位置が変わらないように、仮受材13で支持してもよい。
次に、横梁9を重機で吊り下げ、横梁受け12に設置する(図4(b))。横梁9には、その下部と、石炭塔2内の敷板5aまたは軌条5とを一体化する、支柱11を設けることが好ましい。図5(a)に示したように、敷板5a側に、下部支柱11aを設けて、横梁9を設置する際に、横梁9に設けた支柱11と、下部支柱11aを接続してもよい。支柱11については後にも詳細に説明する。
In order to install the horizontal beam 9 on the column 10, first, the horizontal beam support 12 is provided on the column 10 (FIG. 4A). At this time, the temporary support member 13 may support the horizontal beam receiver 12 so that the installation position of the horizontal beam receiver 12 does not change.
Next, the horizontal beam 9 is suspended by a heavy machine and installed on the horizontal beam receiver 12 (FIG. 4B). It is preferable that the horizontal beam 9 is provided with a column 11 that integrates the lower part thereof and the floor plate 5a or the rail 5 in the coal tower 2. As shown in FIG. 5 (a), when the lower column 11a is provided on the floor 5a side and the horizontal beam 9 is installed, the column 11 provided on the horizontal beam 9 and the lower column 11a may be connected. The column 11 will be described later in detail.
横梁9と横梁受け12は溶接固定をせずに、転倒防止用アングル12dと落下防止用アングル12e、および、横梁9の水平移動を防止するブロック12aの3面で拘束されているが、固定はしてはいないことが好ましい。理由は、衝撃力に対し横梁9の水平移動を防止するブロック12aで受け、石炭塔2の柱10へ直接せん断力等が働かない構造とするためである。 The horizontal beam 9 and the horizontal beam receiver 12 are not fixed by welding, but are restrained by three surfaces of a fall prevention angle 12d, a fall prevention angle 12e, and a block 12a that prevents horizontal movement of the horizontal beam 9. Preferably not. The reason is that a block 12 a that prevents the horizontal beam 9 from moving horizontally against an impact force is used so that a shearing force or the like does not directly act on the column 10 of the coal tower 2.
横梁9を設置した後、図5(b)に示したように、横梁9に車体ストッパー7を設置する。なお、図5(b)において、横梁受け12の記載は省略している。 After the horizontal beam 9 is installed, the vehicle body stopper 7 is installed on the horizontal beam 9 as shown in FIG. In addition, in FIG.5 (b), description of the cross beam receiver 12 is abbreviate | omitted.
本発明では、前述したように、横梁9には、その下部と、石炭塔2内の敷板5aまたは軌条5とを一体化する、支柱11(下部支柱11a)を設けることが好ましい。支柱11(下部支柱11a)を設ける場所は、図6に示したように、車体ストッパー7の真下、装炭車4の軌条5の上が好ましい。なお、図6において、軌条5の記載は省略している。 In the present invention, as described above, it is preferable that the horizontal beam 9 is provided with the support column 11 (lower support column 11a) that integrates the lower portion thereof with the floor plate 5a or the rail 5 in the coal tower 2. As shown in FIG. 6, the place where the column 11 (lower column 11 a) is provided is preferably directly below the vehicle body stopper 7 and above the rail 5 of the charcoal vehicle 4. In addition, in FIG. 6, description of the rail 5 is abbreviate | omitted.
支柱11(下部支柱11a)は、装炭車4が車体ストッパー7へ衝突した際に発生する下方の回転モーメント力を受け止め、車体ストッパー7自体や石炭塔2の柱10に設置した横梁9の構造部材および横梁受け12へ水平力を作用させることで石炭塔2の柱10自体への衝撃力を軽減する役目を果たす。支柱11(下部支柱11a)と、敷板5aまたは軌条5との一体化は、図示しないが溶接や転倒防止アンカーなどにより行えばよい。 The strut 11 (lower strut 11a) receives a lower rotational moment force generated when the coal-equipped vehicle 4 collides with the vehicle body stopper 7, and is a structural member of the cross beam 9 installed on the vehicle body stopper 7 itself or the column 10 of the coal tower 2. Further, by acting a horizontal force on the horizontal beam receiver 12, it plays a role of reducing the impact force on the column 10 itself of the coal tower 2. The column 11 (lower column 11a) and the base plate 5a or the rail 5 may be integrated by welding or a fall prevention anchor, although not shown.
また、柱10と、横梁受け12の係止部12bとの固定には、図6には、図示していないケミカルアンカーを用いることができる。 Further, a chemical anchor not shown in FIG. 6 can be used for fixing the column 10 and the locking portion 12b of the cross beam receiver 12.
車体ストッパー7は、図3(b)に示したように、衝突・停止の際に、装炭車4が最初にあたるような位置と構造で横梁9に設けられれば良く、公知のストッパーを使用できる。たとえば、油圧ダンパーなどを使用できる。車体ストッパー7には、衝撃吸収機能を付与することが好ましい。 As shown in FIG. 3B, the vehicle body stopper 7 may be provided on the cross beam 9 at a position and structure such that the charcoal vehicle 4 first hits at the time of collision / stop, and a known stopper can be used. For example, a hydraulic damper can be used. The vehicle body stopper 7 is preferably provided with an impact absorbing function.
本発明の装炭車4の車止め構造の工事を行う手順としては、たとえば、次のような手順が考えられる。
石炭塔2の柱10に固定する横梁受け12は、装炭車4の走行範囲に支障がないので、解体側Aコークス炉の操業休止より早い段階の月間定修日で取り付ける。横梁9は解体側Aコークス炉への装炭車4の走行が不要となる操業休止当日、あるいは前日の段階で、石炭塔2の柱10間へ重機で吊り上げ設置する。
この横梁9を設置した段階から、既に石炭塔2から解体側Aコークス炉への装炭車4の侵入は防止される。
横梁9の支柱11と敷板5aまたは軌条5を一体化し、横梁9に車体ストッパー7の油圧ダンパーを取り付け、装炭車4の車止め構造は完成する。
For example, the following procedure is conceivable as a procedure for carrying out the construction of the stopping structure of the coal-equipped vehicle 4 of the present invention.
Since the horizontal beam receiver 12 fixed to the column 10 of the coal tower 2 does not hinder the traveling range of the coal-equipped vehicle 4, it is attached at a monthly regular repair date at an earlier stage than the discontinuation of the dismantling side A coke oven. The horizontal beam 9 is suspended and installed between the pillars 10 of the coal tower 2 by heavy equipment on the day of the operation suspension or the day before the time when the coal-car 4 is not required to travel to the dismantling side A coke oven.
From the stage at which the horizontal beam 9 is installed, the coal car 4 can be prevented from entering the demolition side A coke oven from the coal tower 2 already.
The support 11 of the horizontal beam 9 and the floor plate 5a or the rail 5 are integrated, and the hydraulic damper of the vehicle body stopper 7 is attached to the horizontal beam 9, and the vehicle stop structure of the coal-equipped vehicle 4 is completed.
本発明により、コークス炉の更新工事の際に設ける、装炭車4の車止め構造を、短い工事期間と安い工事費用で設けることができ、更新工事後に車止め構造を撤去することも容易であり、さらに撤去した横梁9は引き続き更新する稼働側Bコークス炉の車止め用に流用できるので、コークス炉の更新工事全体としても、工事期間の短縮や工事費用の抑制が可能となる。 According to the present invention, it is possible to provide the stop structure of the coal-equipped vehicle 4 provided at the time of renewal construction of the coke oven with a short construction period and low construction cost, and it is easy to remove the stop structure after the renewal work. Since the removed cross beam 9 can be used for stopping the operation side B coke oven to be continuously updated, the construction period can be shortened and the construction cost can be reduced as a whole of the coke oven renewal construction.
