Description
本発明は、港湾や内陸地のコンテナターミナルなどで、コンテナの荷役に使用されるクレーン等、特に大型船対応の岸壁クレーンの構造に関するものである。
The present invention relates to the structure of a quay crane for a large ship, such as a crane used for container handling at a port or an inland container terminal.
港湾や内陸地等のコンテナターミナルでは、岸壁クレーンや門型クレーンによって、船舶及びトレーラ間のコンテナの荷役を行っている。図４に岸壁クレーン１Ｘの側面図を示しており、岸壁クレーン１Ｘは、海側脚１１と陸側脚１２の下部にそれぞれ走行輪８を有しており、岸壁１８に敷設したレール上を走行可能に設置されている。また、ブーム１０上にトロリ１３を有しており、ガーダ９上に機械室１７を有している。
In container terminals such as harbors and inland areas, containers between ships and trailers are handled by quay cranes and portal cranes. FIG. 4 shows a side view of the quay crane 1X. The quay crane 1X has traveling wheels 8 below the sea side leg 11 and the land side leg 12, respectively, and runs on rails laid on the quay 18. It is installed as possible. A trolley 13 is provided on the boom 10, and a machine room 17 is provided on the girder 9.
岸壁クレーン１Ｘで荷役を行う際、コンテナ船１５内に積載されたコンテナ１４は、矢印で示す荷役パスｐに沿ってトレーラ１６まで運搬される。この荷役パスｐは、コンテナ１４の動きを最短距離として、荷役時間を短縮するように制御されている。そのため、クレーン１Ｘの各構造材料は、この荷役パスｐを妨げないように設計されている。
When carrying out cargo handling with the quay crane 1X, the container 14 loaded in the container ship 15 is conveyed to the trailer 16 along the cargo handling path p shown by the arrow. This cargo handling path p is controlled so as to shorten the cargo handling time with the movement of the container 14 as the shortest distance. Therefore, each structural material of the crane 1X is designed so as not to disturb the cargo handling path p.
図５に岸壁クレーン１Ｘの正面図を示しており、２つの海側脚１１は、シルビーム２Ｘとタイビーム５で連結されており、シルビーム２Ｘの近傍にケーブルリール７が設置されている。荷役パスｐを短くして、荷役効率を向上できるように、シルビーム２Ｘは低い位置に設置されている。
FIG. 5 shows a front view of the quay crane 1X. The two seaside legs 11 are connected by a sill beam 2X and a tie beam 5, and a cable reel 7 is installed in the vicinity of the sill beam 2X. The sill beam 2X is installed at a low position so that the cargo handling path p can be shortened to improve the cargo handling efficiency.
なお、図４に示すコンテナ船１５（例えばデッキ上にコンテナを１３列配置するコンテナ船）は、船底２１から甲板２２までのコンテナ船高さｈｘが１５～２０ｍ程度であり、岸壁クレーン１Ｘの高さＨｘが２５～３０ｍ程度であり、図５に示すクレーンの全幅Ｗが２７ｍ程度であり、全体の重量は７００～８００ｔとなっている。
The container ship 15 shown in FIG. 4 (for example, a container ship in which 13 rows of containers are arranged on the deck) has a container ship height hx from the bottom 21 to the deck 22 of about 15 to 20 m, and the height of the quay crane 1X is high. The height Hx is about 25 to 30 m, the total width W of the crane shown in FIG. 5 is about 27 m, and the total weight is 700 to 800 t.
また、近年、コンテナ輸送の効率を向上させるため、コンテナ船１５の大型化が進んできており、これに伴い、岸壁クレーン１Ｘの大型化の要請がある。岸壁クレーン１Ｘは、大型化により重心が高くなるため、安定性を向上する必要がある。また、荷役効率を上げるために、クレーンの振れをできるだけ抑えるため、構造物の剛性確保が必要である。
Also, in recent years, in order to improve the efficiency of container transportation, the container ship 15 has been increased in size, and accordingly, there is a demand for an increase in the size of the quay crane 1X. Since the center of gravity of the quay crane 1X is increased due to the increase in size, it is necessary to improve the stability. Moreover, in order to increase the cargo handling efficiency, it is necessary to ensure the rigidity of the structure in order to suppress the crane runout as much as possible.
クレーンの安定性を向上と振れの低減のために、クレーンを構成するフレームを大断面化して、剛性を上げる方法が考えられるが、剛性の向上と共にクレーン全体の重量が大幅に増加してしまう。しかし、岸壁１８にはそれぞれ限界となる輪重が決まっているため、輪重を増加させるためには、岸壁の作り直しが必要となり、莫大なコストがかかるという問題を有している。ここで、輪重とは、例えば海側脚３に設置された走行輪１１にかかる荷重のことを指している。
方法 In order to improve the stability of the crane and reduce the swing, it is possible to increase the rigidity by increasing the cross section of the frame that constitutes the crane. However, as the rigidity is improved, the weight of the crane as a whole increases significantly. However, since the limit of wheel load is determined for each quay 18, in order to increase the wheel load, there is a problem that the quay needs to be recreated and enormous cost is required. Here, the wheel load refers to, for example, a load applied to the traveling wheel 11 installed on the seaside leg 3.
また、クレーンの安定性を向上するために、クレーン全幅Ｗを広げる方法が考えられるが、クレーン全幅Ｗを広げると、コンテナ船１５に対して同時に投入できるクレーンの数が減ってしまう問題を有している。つまり、図６に示す様に、コンテナ船１５に搭載されているコンテナ１４の列をベイＢと呼び、４０ｆｔコンテナを想定すると２つのベイＢの幅は約２７ｍ程度となっているが、クレーン全幅Ｗもこの２７ｍ以内に収める必要がある。
Moreover, in order to improve the stability of the crane, a method of widening the crane full width W is conceivable, but if the crane full width W is widened, there is a problem that the number of cranes that can be simultaneously loaded into the container ship 15 is reduced. ing. That is, as shown in FIG. 6, the row of containers 14 mounted on the container ship 15 is called bay B, and assuming a 40 ft container, the width of the two bays B is about 27 m. W must be within 27m.
この問題に対してガーダ上に２つのトロリと受け台を有した岸壁クレーンの軽量化の方法が開示されている（例えば特許文献１参照）。クレーンの軽量化により、安定性を向上させながら、クレーンを大型化することができる。
To solve this problem, a method for reducing the weight of a quay crane having two trolleys and cradles on a girder has been disclosed (for example, see Patent Document 1). By reducing the weight of the crane, it is possible to increase the size of the crane while improving stability.
しかしながら、特許文献１に記載の発明では、受け台をもともと有さない通常の岸壁クレーンにおいて、岸壁クレーン自体の重量を軽量化することができず、岸壁クレーン１Ｘの安定性を向上させることはできない。
However, in the invention described in Patent Document 1, in a normal quay crane that does not originally have a cradle, the weight of the quay crane itself cannot be reduced, and the stability of the quay crane 1X cannot be improved. .
本発明は、上記の問題を解決するためになされたものであり、その目的は、岸壁クレーンにおいて、シルビーム上方の空間の利用により、従来のクレーン並みの輪重で、かつ安定性の高い大型コンテナ船対応の岸壁クレーンを提供することを目的とする。すなわち、クレーン上部に設置されていた大型装置等を低い位置に移動させ、低重心化し、かつ、クレーンの剛性を上げて、クレーンを構成するフレームの軽量化を実現した岸壁クレーンを提供し、さらに、クレーンの脚幅を狭くして（脚を構成するフレーム断面積の縮小化により）、風の受圧面積を減少させ、風荷重を低減して、岸壁に及ぼす輪重を低減した岸壁クレーンを提供することを目的とする。
The present invention has been made in order to solve the above-described problems, and an object of the present invention is to use a space above a sill beam in a quay crane, and to have a large-sized container having a wheel load similar to that of a conventional crane and high stability. The purpose is to provide a quay crane for ships. That is, a quay crane is provided that moves a large device or the like installed on the upper part of the crane to a lower position, lowers the center of gravity, increases the rigidity of the crane, and realizes weight reduction of the frame constituting the crane. , Providing a quay crane that narrows the leg width of the crane (by reducing the cross-sectional area of the frame that constitutes the leg), reduces the wind pressure area, reduces the wind load, and reduces the wheel load on the quay The purpose is to do.

In the above quay crane, at least one of a control panel, a high voltage panel, a transformer, a distribution board, and a lighting ballast is installed inside the sill beam.
上記の目的を達成するための本発明に係る岸壁クレーンは、海上用輸送コンテナを荷役する岸壁クレーンにおいて、前記岸壁クレーンを構成するシルビーム上部に補強部材を設置し、かつ、前記岸壁クレーンに設置している装置のうち少なくとも１つを設置したことを特徴とする。
To achieve the above object, a quay crane according to the present invention is a quay crane for handling a marine transport container, wherein a reinforcing member is installed above the sill beam constituting the quay crane, and is installed on the quay crane. At least one of the devices is installed.
上記の岸壁クレーンにおいて、前記シルビーム上部にケーブルリール、監視員室、リモートオペレーション用運転室を設置したことを特徴とする。

In the above quay crane, a reinforcing member is installed on the upper part of the sill beam, the reinforcing member is formed as a platform, and the platform is a work place for attaching and detaching a stacking cone.
シルビームを大断面箱梁形状（ＢＯＸ形状）とした構成により、クレーン脚部の剛性を向上させ、かつ、シルビーム内にクレーンに設置されている装置を設置する構成により、クレーンの重心を下げることができる。そのため、クレーンの安定性が増し、クレーンの他の構造の軽量化が可能となり、既設の岸壁に大型岸壁クレーンを設置することができる。この軽量化により、輪重を低減することが可能となり、岸壁を新設する場合は、基礎強度を低減させた土木建築コストを抑えた設備の提案が可能となる。
The construction of the sill beam with a large cross-section box beam shape (BOX shape) improves the rigidity of the crane legs, and the construction that installs the equipment installed on the crane in the sill beam can lower the center of gravity of the crane. it can. Therefore, the stability of the crane is increased, the weight of the other structure of the crane can be reduced, and a large quay crane can be installed on the existing quay. This weight reduction makes it possible to reduce the wheel load, and in the case of newly installing a quay, it is possible to propose a facility with reduced foundation strength and reduced construction cost.
ここで、シルビーム内に設置する装置は、可能な限り多い方が望ましく、また、重量の大きいものを優先的に設置する方が望ましく、これにより低重心化の効果がより大きくなる。また、クレーン上部の機械室等に設置していた装置を、地上に近いシルビーム内に設置する構成により、これらの装置に対して、地上からのアクセスがよくなり、メンテナンス性を向上することができる。
Here, it is desirable that the number of devices installed in the sill beam is as many as possible, and it is desirable to preferentially install a device having a large weight, and thereby the effect of lowering the center of gravity is further increased. In addition, by installing the devices installed in the machine room above the crane in the sill beam close to the ground, these devices can be easily accessed from the ground and the maintainability can be improved. .
更に、制御盤、高圧盤、変圧器、分電盤、照明安定器等のクレーンに設置されている機器を、シルビーム内に設置するとよい。これはシルビームがＢＯＸ形状のため、その内部は風雨を防ぐことが可能であり、特に風雨に弱い電気装置等を設置することが望ましい。
Furthermore, equipment installed in cranes such as control panels, high voltage panels, transformers, distribution boards, and lighting ballasts should be installed in the sill beam. Since the sill beam has a BOX shape, it is possible to prevent wind and rain inside, and it is desirable to install an electric device or the like that is particularly vulnerable to wind and rain.
また、シルビーム上部の空間に斜材等の補強部材を設置する構成により、岸壁クレーンの脚の剛性が向上し、脚を構成するフレームの断面を小さくすることができる。その結果、クレーンを軽量化することができる。さらに、シルビーム上部の空間にケーブルリール、監視員室、リモートオペレーション用運転室等を設置する構成により、岸壁クレーンを低重心化し、安定性を向上することができる。
Also, by installing a reinforcing member such as diagonal material in the space above the sill beam, the rigidity of the legs of the quay crane can be improved and the cross section of the frame constituting the legs can be reduced. As a result, the crane can be reduced in weight. Furthermore, by installing a cable reel, a supervisor room, a remote operation cab, etc. in the space above the sill beam, the quay crane can have a low center of gravity and stability can be improved.
更に、シルビーム上部にプラットホームを形成する構成により、岸壁クレーンの剛性を向上させると共に、スタッキングコーンの着脱作業を行う空間を確保することができるため、トレーラ等のコンテナ運搬装置と地上作業者の作業場所を沸けることで、荷役作業の安全性を向上させることができる。
Furthermore, because the platform is formed on the top of the sill beam, the rigidity of the quay crane can be improved and a space for attaching and detaching the stacking cone can be secured. The safety of cargo handling work can be improved by boiling.
以下、本発明に係る実施の形態の岸壁クレーンについて、図面を参照しながら説明する。図１に、岸壁クレーン１Ａの正面図を示しており、２つの海側脚１１を連結しているフレームの内、下部にあたるシルビーム２Ａを大断面箱梁形状（ＢＯＸ形状）として、更に上部に補強部材を板状に形成したプラットホーム４を設置している。
Hereinafter, a quay crane according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a front view of a quay crane 1A, and a sill beam 2A corresponding to a lower part of a frame connecting two seaside legs 11 is formed into a large cross-section box beam shape (BOX shape) and further reinforced at the upper part. A platform 4 in which members are formed in a plate shape is installed.
シルビーム２Ａは、例えば１ｍ×２．５ｍの矩形の断面を有していた従来のシルビームを、１．５～３ｍ×３～１０ｍの矩形の断面を有したものに変更し、シルビーム２Ａの内部には、従来、岸壁クレーンの海側脚１１と陸側脚１２の間にあたる側面部に設置していたケーブルリールや、機械室１７内に設置していた制御盤、高圧盤、変圧器、分電盤、照明安定器等の大型装置を設置しており、この構成により、大型の岸壁クレーン１Ａの低重心化を実現することができる。
For the sill beam 2A, for example, a conventional sill beam having a rectangular cross section of 1 m × 2.5 m is changed to one having a rectangular cross section of 1.5 to 3 m × 3 to 10 m, and the sill beam 2A is placed inside the sill beam 2A. Conventionally, cable reels installed on the side surface between the sea side leg 11 and the land side leg 12 of the quay crane, and the control panel, high voltage panel, transformer, power distribution installed in the machine room 17 Large devices such as panels and lighting ballasts are installed. With this configuration, a low center of gravity of the large quay crane 1A can be realized.
プラットホーム４は、上面を板状としており、補強部材でありながら、スタッキングコーン等の着脱作業を行う作業場として使用することができる。ここで、プラットホーム４はシルビーム１Ａに固定するか、海側脚１１の間に固定され、補強部材として機能するように設置することが望ましいが、補強部材としての機能を有さない場合であっても、荷役作業の高効率化には寄与することができる。なお、スタッキングコーンとは、コンテナ船１５において、コンテナ１４を互いに連結するための連結具であり、コンテナターミナルにコンテナ１４を載置する際には除去されるものである。
The platform 4 has a plate-like upper surface and can be used as a work place where a stacking cone or the like is attached or detached while being a reinforcing member. Here, it is desirable that the platform 4 is fixed to the sill beam 1A or fixed between the sea-side legs 11 so as to function as a reinforcing member, but it does not have a function as a reinforcing member. However, it can contribute to higher efficiency of the cargo handling work. The stacking cone is a connecting tool for connecting the containers 14 to each other on the container ship 15, and is removed when the containers 14 are placed on the container terminal.
図１の岸壁クレーン１Ａの構成により、岸壁クレーン１Ａの安定性が向上するため、脚１１、１２等のフレームをサイズダウンすることが可能となり、軽量化を実現することができる。また、特に上部脚のフレームのサイズダウンにより、風を受ける上部構造物の受圧面積が低減され、岸壁クレーン１Ａの走行時の風抵抗が低減される。このため、走行モータの容量を下げることが可能となり、電力消費の低減が実現できる。
1 The stability of the quay crane 1A is improved by the configuration of the quay crane 1A shown in FIG. 1, so that the frames such as the legs 11 and 12 can be downsized, and the weight can be reduced. In particular, the size reduction of the frame of the upper leg reduces the pressure receiving area of the upper structure that receives the wind, and the wind resistance during travel of the quay crane 1A is reduced.

図２に、本発明に係る異なる実施の形態の岸壁クレーン１Ｂの正面図を示しており、シルビーム２Ｂ上部に補強部材３Ａ、３Ｂを設置して、更に補強部材３の上部に板状に形成したプラットホーム４を設置して、シルビーム２Ｂ上部にケーブルリール７を設置している。なお、補強部材３の設置位置は岸壁クレーン１Ｂの剛性を上げるために適切に選択することが可能であり、図２に示すパターンに限定されない。
FIG. 2 shows a front view of a quay crane 1B according to a different embodiment of the present invention, in which reinforcing members 3A and 3B are installed on the upper part of the sill beam 2B, and further formed in a plate shape on the upper part of the reinforcing member 3. A platform 4 is installed, and a cable reel 7 is installed above the sill beam 2B. The installation position of the reinforcing member 3 can be appropriately selected to increase the rigidity of the quay crane 1B, and is not limited to the pattern shown in FIG.
ケーブルリール７をシルビーム２Ｂの上部に設置することにより、図５の従来の岸壁クレーン１Ｘと比べ、クレーンの全幅Ｗの長さを小さくすることができる。また、ケーブルリール等の大型装置は、斜材３Ａ等により保護されるため、コンテナ１４等の接触により故障する事故等を抑制することができる。
By installing the cable reel 7 on the top of the sill beam 2B, the length of the entire width W of the crane can be reduced as compared with the conventional quay crane 1X in FIG. In addition, since a large-sized device such as a cable reel is protected by the diagonal material 3A or the like, it is possible to suppress an accident caused by a contact with the container 14 or the like.
図３に、岸壁クレーン１Ｂの側面図を示しており、コンテナ船１５に載置されたコンテナ１４は、海側トロリ１３ａで吊り上げられて横行体１９に載置され、横行体１９により水平方向に運ばれ、陸側トロリ１３ｂによりトレーラ１６に下ろされる荷役パスｐを通るように荷役される。コンテナ船１５の大型化（例えばデッキ上にコンテナを１８列以上配置するコンテナ船）により、荷役パスｐがシルビーム２上部の空間を通らなくなったため、この空間を有効利用することが可能となっている。つまり、荷役パスｐを妨げない範囲で、シルビーム２のＢＯＸ形状化や補強部材３の設置が可能となり、岸壁１８の地面から１０～１３ｍ程度の高さまで利用することができる。ここで、岸壁クレーン１Ｂの高さＨは７０～８０ｍ程度であり、コンテナ船１５の高さｈは２５～３０ｍ程度であり、クレーンの全体重量は１０００～１５００ｔである。
FIG. 3 shows a side view of the quay crane 1B. The container 14 placed on the container ship 15 is lifted by the sea-side trolley 13a and placed on the traversing body 19, which is moved horizontally by the traversing body 19. Carried and handled by the land-side trolley 13b so as to pass the cargo handling path p that is lowered to the trailer 16. Due to the increase in size of the container ship 15 (for example, a container ship in which 18 or more rows of containers are arranged on the deck), the cargo handling path p does not pass through the space above the sill beam 2, so that this space can be used effectively. . In other words, the sill beam 2 can be shaped into a BOX and the reinforcing member 3 can be installed within a range that does not hinder the cargo handling path p, and can be used up to a height of about 10 to 13 m from the ground of the quay wall 18. Here, the height H of the quay crane 1B is about 70 to 80 m, the height h of the container ship 15 is about 25 to 30 m, and the total weight of the crane is 1000 to 1500 t.
また、本発明は通常のトロリ１３を１台のみ有した大型の岸壁クレーンにも適用することが可能であるが、図３に示す横行体１９及び２台のトロリ１３ａ、１３ｂを有した岸壁クレーン１Ｂに適用した際に、さらに有効な作用効果を得ることができる。
Further, the present invention can be applied to a large quay crane having only one normal trolley 13, but a quay crane having a traversing body 19 and two trolleys 13a and 13b shown in FIG. When applied to 1B, more effective functions and effects can be obtained.
なお、本発明は陸側脚１２を連結しているシルビームには適用しない。これは、船舶のハッチカバー等の大型荷物をトロリ１３で吊り上げ、岸壁クレーンの後背地に設置する場合があり、その際の荷役パスｐを、妨げる可能性があるためである。
The present invention is not applied to a sill beam connecting the land-side legs 12. This is because a large luggage such as a hatch cover of a ship may be lifted by the trolley 13 and installed on the back ground of the quay crane, which may hinder the cargo handling path p at that time.
図６に、岸壁クレーン１の上面図を示しており、岸壁クレーン１は担当しているベイＢの荷揚げが完了すると、走行レール２０上を自走し、次のベイＢに移るように構成されている。この岸壁クレーン１の走行に伴い、ブーム先端１０ａが揺れるが、この揺れを約２５０ｍｍ（走行変位制限値）以内とする必要がある。
FIG. 6 shows a top view of the quay crane 1, and the quay crane 1 is configured to self-travel on the traveling rail 20 and move to the next bay B when the unloading of the bay B in charge is completed. ing. As the quay crane 1 travels, the boom tip 10a swings, but this swing needs to be within about 250 mm (travel displacement limit value).
本発明を適用した岸壁クレーン１Ａ、１Ｂは、クレーンを大型化しても剛性が向上しているため、ガーダ先端１０ａの揺れを小さく抑えることが可能であり、岸壁クレーンの移動後に荷役作業を迅速に開始することができ、荷役効率を向上することができる。
Since the quay cranes 1A and 1B to which the present invention is applied have improved rigidity even if the crane is enlarged, it is possible to suppress the shaking of the girder tip 10a to be small, and the cargo handling work can be quickly performed after the quay crane is moved. It can be started, and cargo handling efficiency can be improved.
