　連続式アンローダによる荷役中に、海のうねりが高くなると、揺動している船舶から連続式アンローダへ荷重がかかる可能性がある。このとき、バケットが無端状チェーンを支持するボトムピースに衝突するなどして、連続式アンローダの部材が破損したり転倒したりする危険性があった。一方、従来、海のうねりの監視は、連続式アンローダのオペレータの目視によって行われており、船舶の揺動、特に船舶の上下動の確認は困難であった。 If the sea swell increases during cargo handling by a continuous unloader, there is a possibility that a load is applied to the continuous unloader from the oscillating ship. At this time, there is a risk that the member of the continuous unloader is damaged or falls due to the bucket colliding with the bottom piece supporting the endless chain. On the other hand, conventionally, monitoring of sea swell has been performed by visual observation by an operator of a continuous unloader, and it has been difficult to confirm the swinging of the ship, particularly the vertical movement of the ship.
　本発明は、このような事情に鑑みてなされたものであって、荷役中の船舶の動きを正確に把握して、船舶から連続式アンローダにかかる荷重を低減することが可能な連続式アンローダを提供することを目的とする。 The present invention has been made in view of such circumstances, and is a continuous unloader capable of accurately grasping the movement of a ship during cargo handling and reducing the load applied to the continuous unloader from the ship. The purpose is to provide.
　上記課題を解決するために、本発明の連続式アンローダは以下の手段を採用する。
　すなわち、本発明の第１の態様に係る連続式アンローダは、船舶の船倉内に積載されたバラ荷を掘削するバケットと、複数のバケットが接続された無端状部材と、無端状部材を駆動する駆動部とを有する掘削手段と、船舶の揺動を検出する揺動検出手段と、検出された揺動を視覚的に表示する表示手段とを備える。 In order to solve the above problems, the continuous unloader of the present invention employs the following means.
That is, the continuous unloader according to the first aspect of the present invention drives a bucket for excavating bulk loads loaded in a ship hold, an endless member connected to a plurality of buckets, and an endless member. Excavation means having a drive unit, swing detection means for detecting the swing of the ship, and display means for visually displaying the detected swing.
　本発明の第１の態様によれば、無端状部材が駆動することによって、無端状部材に接続された複数のバケットが船舶の船倉内に積載されたバラ荷を連続的に掘削する。また、揺動検出手段によってバラ荷の掘削が行われている船舶の揺動が検出され、検出された揺動が表示手段に表示されることから、船舶の揺動に応じた掘削手段の運転の変更を正確に行うことができる。例えば、掘削手段のオペレータに船舶の揺動状態が伝わることで、荷役時の掘削手段の操作の手助けとなる。また、船舶側にいるオペレータへの指示者（合図マン）に船舶の揺動状態が伝わることで、荷役時の操作指示の手助けとなる。具体的には、船舶の揺動に応じて、船舶から掘削手段にかかる荷重を低減するように掘削手段が運転される。 According to the first aspect of the present invention, when the endless member is driven, a plurality of buckets connected to the endless member continuously excavate the bulk load loaded in the ship hold. In addition, since the swing detection means detects the swing of the ship that is excavating the loose load, and the detected swing is displayed on the display means, the operation of the drilling means according to the swing of the ship is performed. Can be made accurately. For example, the state of rocking of the ship is transmitted to the operator of the excavation means, which helps the operation of the excavation means during cargo handling. In addition, when the ship's rocking state is transmitted to an instructor (signal man) to the operator on the ship side, it is possible to assist in operating instructions during cargo handling. Specifically, the excavation means is operated so as to reduce the load applied to the excavation means from the ship according to the swinging of the ship.
　本発明の第１の態様において、揺動検出手段は、掘削手段に設置される構成としてもよい。 In the first aspect of the present invention, the swing detection means may be installed on the excavation means.
　上記構成によれば、掘削手段に揺動検出手段が設けられることから、船舶側から掘削手段側への信号伝送手段、例えば船舶上への無線装置の設置が不要になる。 According to the above configuration, since the excavation means is provided with the swing detection means, it is not necessary to install a signal transmission means from the ship side to the excavation means side, for example, a wireless device on the ship.
　また、本発明の第２の態様に係る連続式アンローダは、船舶の船倉内に積載されたバラ荷を掘削するバケットと、複数のバケットが接続された無端状部材と、無端状部材を駆動する駆動部とを有する掘削手段と、船舶と掘削手段との近接状態を検出する近接状態検出手段と、検出された近接状態を告知する告知手段とを備える。 Moreover, the continuous unloader which concerns on the 2nd aspect of this invention drives the endless member which excavated the bulk load loaded in the hold of a ship, the endless member to which the several bucket was connected, and the endless member Excavation means having a drive unit, proximity state detection means for detecting the proximity state of the ship and the excavation means, and notification means for notifying the detected proximity state.
　本発明の第２の態様によれば、無端状部材が駆動することによって、無端状部材に接続された複数のバケットが船舶の船倉内に積載されたバラ荷を連続的に掘削する。また、近接状態検出手段によってバラ荷の掘削が行われている船舶の近接状態が検出され、検出された近接状態が告知されることから、船舶の近接状態に応じた掘削手段の運転の変更を正確に行うことができる。例えば、掘削手段のオペレータに船舶の近接状態が伝わることで、荷役時の掘削手段の操作の手助けとなる。具体的には、船舶の近接状態に応じて、干渉を回避できるように掘削手段が運転される。 According to the second aspect of the present invention, when the endless member is driven, a plurality of buckets connected to the endless member continuously excavate the bulk load loaded in the ship hold. In addition, since the proximity state of the ship that is excavating loose loads is detected by the proximity state detection means, and the detected proximity state is notified, the operation of the excavation means is changed according to the proximity state of the ship. Can be done accurately. For example, the proximity of the ship is transmitted to the operator of the excavation means, which helps the operation of the excavation means during cargo handling. Specifically, the excavating means is operated so as to avoid interference according to the proximity state of the ship.
　また、本発明の第３の態様に係る連続式アンローダは、船舶の船倉内に積載されたバラ荷を掘削するバケットと、複数のバケットが接続された無端状部材と、無端状部材を駆動する駆動部とを有する掘削手段と、船舶の揺動量を検出する揺動検出手段と、検出された揺動量に応じて掘削手段の無端状部材のたるみ量又はバラ荷と掘削手段との距離を変更する操作手段とを備える。 Further, the continuous unloader according to the third aspect of the present invention drives a bucket for excavating bulk loads loaded in a ship hold, an endless member connected to a plurality of buckets, and an endless member. Excavation means having a drive unit, oscillation detection means for detecting the amount of oscillation of the ship, and the amount of sagging of the endless member of the excavation means or the distance between the bulk load and the excavation means is changed according to the detected oscillation amount Operating means.
　本発明の第３の態様によれば、無端状部材が駆動することによって、無端状部材に接続された複数のバケットが船舶の船倉内に積載されたバラ荷を連続的に掘削する。また、揺動検出手段によってバラ荷の掘削が行われている船舶の揺動量が検出され、検出された揺動量に応じて、掘削手段の無端状部材のたるみ量又はバラ荷と掘削手段との距離が変更されることから、船舶の揺動に応じた掘削手段の運転の変更を正確に行うことができる。その結果、船舶の揺動に応じて、船舶から掘削手段にかかる荷重を低減するように掘削手段が操作される。 According to the third aspect of the present invention, when the endless member is driven, a plurality of buckets connected to the endless member continuously excavate the bulk load loaded in the hold of the ship. Further, the swing detection means detects the swing amount of the vessel on which the bulk load is excavated, and depending on the detected swing amount, the sagging amount of the endless member of the drilling means or the loose load and the excavation means Since the distance is changed, it is possible to accurately change the operation of the excavation means according to the swinging of the ship. As a result, the excavation means is operated so as to reduce the load applied to the excavation means from the ship according to the swinging of the ship.
　本発明によれば、荷役中の船舶の動きを正確に把握して、船舶から連続式アンローダにかかる荷重を低減することができる。 According to the present invention, it is possible to accurately grasp the movement of the ship during cargo handling and reduce the load applied to the continuous unloader from the ship.

First, the configuration of the continuous unloader 1 according to the present embodiment will be described.
The continuous unloader 1 is installed on the quay 5, and the main body 4 of the continuous unloader 1 is movable along a rail 36 laid on the quay 5.

As shown in FIG. 5, the endless chain 10 passes through the tip sprocket 32 and the rear end sprocket 33 at the lower part of the excavating means. The front end sprocket 32 and the rear end sprocket 33 are supported by, for example, the bottom piece 31.
　船舶６は、荷役中、岸壁５に沿って停泊しており、海のうねりの影響を受ける。そのため、海のうねりが高くなると、船舶６が連続式アンローダ１に衝突するおそれがある。例えば、ボトムピース３１の下側を通過するバケット３が船底や積載されているバラ荷に当たり、更にバケット３が上側に移動して、ボトムピース３１に衝突する可能性がある。 The ship 6 is anchored along the quay 5 during cargo handling and is affected by sea swells. Therefore, when the sea swell increases, the ship 6 may collide with the continuous unloader 1. For example, there is a possibility that the bucket 3 passing below the bottom piece 31 hits the bottom of the ship or a bulk load, and the bucket 3 further moves upward and collides with the bottom piece 31.
　本実施形態では、揺動検出手段が荷役中の船舶６の揺動を検出し、表示手段が検出された揺動を視覚的に表示する。その結果、表示手段で表示された船舶の揺動に応じて掘削手段を操作することで、海のうねりが高い場合でも荷役を継続することができる。また、海のうねりの高さによっては、荷役中止の判断を迅速かつ正確に行える。 In this embodiment, the swing detection means detects the swing of the ship 6 that is being handled, and the display means visually displays the detected swing. As a result, by operating the excavating means according to the swing of the ship displayed on the display means, it is possible to continue the cargo handling even when the sea swell is high. In addition, depending on the height of the sea swell, it is possible to quickly and accurately determine whether to stop handling.
　以下、本実施形態に係る揺動検出手段について説明する。
　揺動検出手段は、図１に示すように、連続式アンローダ１に設けられたレーザ距離計１５及びぶれ検出カメラ１６と、船舶６に設けられたぶれ検出ターゲット１７からなる。そして、船舶６の甲板面をＸＹ面とし、甲板面に対して垂直方向をＺ方向としたとき、レーザ距離計１５がＺ方向の船舶６の上下動を検出する。また、ぶれ検出カメラ１６とぶれ検出ターゲット１７の組み合わせによって、Ｘ方向やＹ方向の船舶６の揺動を検出する。 Hereinafter, the rocking | swiveling detection means which concerns on this embodiment is demonstrated.
As shown in FIG. 1, the swing detection means includes a laser distance meter 15 and a shake detection camera 16 provided in the continuous unloader 1 and a shake detection target 17 provided in the ship 6. Then, when the deck surface of the ship 6 is the XY plane and the direction perpendicular to the deck surface is the Z direction, the laser rangefinder 15 detects the vertical movement of the ship 6 in the Z direction. Further, the combination of the shake detection camera 16 and the shake detection target 17 detects the swing of the ship 6 in the X direction or the Y direction.
　検出された船舶６の動きに関する信号は、レーザ距離計１５及びぶれ検出カメラ１６から制御部に送信される。そして、検出された信号に基づいて、表示手段は、例えばＸ，Ｙ，Ｚ方向それぞれの船舶６の動きを波形によって表示する。制御部や表示手段は、例えば連続式アンローダ１のオペレータ室に設置される。船舶６の動きは、波形ではなく、数値やインジケータなどで表示してもよい。 The signal relating to the detected movement of the ship 6 is transmitted from the laser distance meter 15 and the shake detection camera 16 to the control unit. Based on the detected signal, the display means displays, for example, the movement of the ship 6 in the X, Y, and Z directions as waveforms. A control part and a display means are installed in the operator room of the continuous unloader 1, for example. The movement of the ship 6 may be displayed not by a waveform but by a numerical value or an indicator.
　これによって、連続式アンローダ１のオペレータが船舶６の揺動量、周期を把握することができ、荷役時の掘削手段の操作の手助けとなる。また、船舶６の揺動量によって、バラ荷とバケット３との隙間に設ける相対距離の目安を連絡することも可能になる。レーザ距離計１５及びぶれ検出カメラ１６は、連続式アンローダ１側に取り付けられ、船舶６側に取り付けられないことから信号伝送のための無線装置が不要である。 This makes it possible for the operator of the continuous unloader 1 to grasp the amount and cycle of the ship 6 and to assist the operation of the excavation means during cargo handling. In addition, it is possible to inform the standard of the relative distance provided in the gap between the loose load and the bucket 3 according to the swinging amount of the ship 6. Since the laser distance meter 15 and the shake detection camera 16 are attached to the continuous unloader 1 side and are not attached to the ship 6 side, a wireless device for signal transmission is unnecessary.
［第２実施形態］
　次に、本発明の第２実施形態について、図２を用いて説明する。
　本実施形態は、連続式アンローダ１の本体部４及び掘削手段について、第１実施形態と同様であるため、詳細な説明は省略する。 [Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG.
Since this embodiment is the same as that of 1st Embodiment about the main-body part 4 and excavation means of the continuous unloader 1, detailed description is abbreviate | omitted.
　本実施形態では、近接状態検出手段が荷役中の連続式アンローダ１と船舶６のコラム２との近接状態を検出し、告知手段（例えば警報装置）が検出された近接状態を告知（鳴動）する。その結果、警報装置で告知された船舶の近接状態に応じて掘削手段を操作することで、海のうねりが高い場合でも荷役を継続することができる。また、海のうねりの高さによっては、荷役中止の判断を迅速かつ正確に行える。 In the present embodiment, the proximity state detection means detects the proximity state between the continuous unloader 1 during cargo handling and the column 2 of the ship 6, and the notification means (for example, an alarm device) notifies (sounds) the detected proximity state. . As a result, cargo handling can be continued even when the swell of the sea is high by operating the excavating means according to the proximity state of the ship notified by the alarm device. In addition, depending on the height of the sea swell, it is possible to quickly and accurately determine whether to stop handling.
　近接状態検出手段は、図２に示すように、船舶６の開口部７の縁に設けられた投光側光電センサ１１及び受光側光電センサ１２と、船舶６に設けられた信号送信用無線装置１３と、連続式アンローダ１に設けられた信号受信用無線装置１８（図１参照）からなる。そして、投光側光電センサ１１及び受光側光電センサ１２が、開口部７に挿入されたコラム２と、船舶６の甲板８との干渉を検出する。また、投光側光電センサ１１及び受光側光電センサ１２で検出された信号が、信号送信用無線装置１３と信号受信用無線装置１８を介して制御部に送られる。次に、制御部は、投光側光電センサ１１及び受光側光電センサ１２で検出された信号に基づいて、干渉に関して告知するか否かを判断し、必要な場合、告知手段が連続式アンローダ１と船舶６のコラム２とが近接していることを知らせる。制御部や告知手段は、例えば連続式アンローダ１のオペレータ室に設置される。 As shown in FIG. 2, the proximity state detecting means includes a light projecting side photoelectric sensor 11 and a light receiving side photoelectric sensor 12 provided at the edge of the opening 7 of the ship 6, and a signal transmitting radio device provided in the ship 6. 13 and a signal receiving radio device 18 (see FIG. 1) provided in the continuous unloader 1. The light projecting side photoelectric sensor 11 and the light receiving side photoelectric sensor 12 detect interference between the column 2 inserted into the opening 7 and the deck 8 of the ship 6. The signals detected by the light projecting side photoelectric sensor 11 and the light receiving side photoelectric sensor 12 are sent to the control unit via the signal transmitting radio device 13 and the signal receiving radio device 18. Next, the control unit determines whether or not to notify about interference based on the signals detected by the light projecting side photoelectric sensor 11 and the light receiving side photoelectric sensor 12, and if necessary, the notifying unit detects the continuous unloader 1. And the column 2 of the ship 6 are in close proximity. A control part and a notification means are installed in the operator room of the continuous unloader 1, for example.
　これによって、連続式アンローダ１のオペレータが連続式アンローダ１と船舶６のコラム２との干渉の危険性を把握することができ、荷役時の掘削手段の操作の手助けとなる。また、告知手段として、モータサイレンなどを用いれば、干渉の危険性を周囲に知らせることが可能になる。 This makes it possible for the operator of the continuous unloader 1 to grasp the danger of interference between the continuous unloader 1 and the column 2 of the ship 6 and to assist the operation of the excavation means during cargo handling. Further, if a motor siren or the like is used as the notification means, it is possible to notify the surroundings of the danger of interference.
［第３実施形態］
　次に、本発明の第３実施形態について、図３を用いて説明する。
　本実施形態は、連続式アンローダ１の本体部４及び掘削手段について、第１実施形態と同様であるため、詳細な説明は省略する。 [Third Embodiment]
Next, a third embodiment of the present invention will be described with reference to FIG.
Since this embodiment is the same as that of 1st Embodiment about the main-body part 4 and excavation means of the continuous unloader 1, detailed description is abbreviate | omitted.
　本実施形態では、揺動検出手段が荷役中の船舶６の揺動を検出し、表示手段が検出された揺動を視覚的に表示する。その結果、表示手段で表示された船舶の揺動に応じて掘削手段を操作することで、海のうねりが高い場合でも荷役を継続することができる。また、海のうねりの高さによっては、荷役中止の判断を迅速かつ正確に行える。 In this embodiment, the swing detection means detects the swing of the ship 6 that is being handled, and the display means visually displays the detected swing. As a result, by operating the excavating means according to the swing of the ship displayed on the display means, it is possible to continue the cargo handling even when the sea swell is high. In addition, depending on the height of the sea swell, it is possible to quickly and accurately determine whether to stop handling.
　次に、本実施形態に係る揺動検出手段について説明する。
　揺動検出手段は、図３に示すように、船舶６に設けられたＧＰＳ２１及び信号送信用無線装置１３と、連続式アンローダ１に設けられた信号受信用無線装置１８（図１参照）からなる。そして、船舶６の甲板面をＸＹ面とし、甲板面に対して垂直方向をＺ方向としたとき、ＧＰＳ２１が、Ｘ方向やＹ方向の船舶６の揺動、Ｚ方向の船舶６の上下動を検出する。 Next, the swing detection means according to this embodiment will be described.
As shown in FIG. 3, the swing detection means includes a GPS 21 and a signal transmitting radio device 13 provided in the ship 6, and a signal receiving radio device 18 (see FIG. 1) provided in the continuous unloader 1. . When the deck surface of the ship 6 is the XY plane and the direction perpendicular to the deck surface is the Z direction, the GPS 21 swings the ship 6 in the X direction and the Y direction and moves the ship 6 in the Z direction up and down. To detect.
　ＧＰＳ２１で検出された船舶６の動きに関する信号は、信号送信用無線装置１３から信号受信用無線装置１８を介して制御部に送信される。そして、検出された信号に基づいて、表示手段に例えばＸ，Ｙ，Ｚ方向それぞれの船舶６の動きを波形によって表示する。制御部や表示手段は、例えば連続式アンローダ１のオペレータ室に設置される。船舶６の動きは、波形ではなく、数値やインジケータなどで表示してもよい。 A signal related to the movement of the ship 6 detected by the GPS 21 is transmitted from the signal transmission wireless device 13 to the control unit via the signal reception wireless device 18. Based on the detected signal, the movement of the ship 6 in the X, Y, and Z directions, for example, is displayed as a waveform on the display means. A control part and a display means are installed in the operator room of the continuous unloader 1, for example. The movement of the ship 6 may be displayed not by a waveform but by a numerical value or an indicator.
　これによって、連続式アンローダ１のオペレータが船舶６の揺動量、周期を把握することができ、荷役時の掘削手段の操作の手助けとなる。また、船舶６の揺動量によって、バラ荷とバケット３との隙間に設ける相対距離の目安を連絡することも可能になる。さらに、無線通信手段を使用することによって、船舶６側と連続式アンローダ１側との信号用配線が不要になる。また更に、ＧＰＳ２１について、図３に示すように、例えば４台を船舶６の各所に設置することによって、船舶６全体の揺動量を把握できる。 This makes it possible for the operator of the continuous unloader 1 to grasp the amount and cycle of the ship 6 and to assist the operation of the excavation means during cargo handling. In addition, it is possible to inform the standard of the relative distance provided in the gap between the loose load and the bucket 3 according to the swinging amount of the ship 6. Furthermore, the use of wireless communication means eliminates the need for signal wiring between the ship 6 side and the continuous unloader 1 side. Further, as shown in FIG. 3, for example, by installing four GPS 21 at various locations on the ship 6, the amount of rocking of the entire ship 6 can be grasped.
［第４実施形態］
　次に、本発明の第４実施形態について、図４を用いて説明する。
　本実施形態は、連続式アンローダ１の本体部４及び掘削手段について、第１実施形態と同様であるため、詳細な説明は省略する。 [Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described with reference to FIG.
Since this embodiment is the same as that of 1st Embodiment about the main-body part 4 and excavation means of the continuous unloader 1, detailed description is abbreviate | omitted.
　本実施形態では、揺動検出手段が荷役中の船舶６の揺動を検出し、表示手段が検出された揺動を視覚的に表示する。その結果、表示手段で表示された船舶の揺動に応じて掘削手段を操作することで、海のうねりが高い場合でも荷役を継続することができる。また、海のうねりの高さによっては、荷役中止の判断を迅速かつ正確に行える。 In this embodiment, the swing detection means detects the swing of the ship 6 that is being handled, and the display means visually displays the detected swing. As a result, by operating the excavating means according to the swing of the ship displayed on the display means, it is possible to continue the cargo handling even when the sea swell is high. In addition, depending on the height of the sea swell, it is possible to quickly and accurately determine whether to stop handling.
　次に、本実施形態に係る揺動検出手段について説明する。
　揺動検出手段は、図４に示すように、船舶６の甲板８上に設けられた２台の傾斜計２５及び信号送信用無線装置１３と、連続式アンローダ１に設けられた信号受信用無線装置１８（図１参照）からなる。そして、傾斜計２５が、船舶６の傾斜角度、例えばピッチ角又はロール角を検出する。 Next, the swing detection means according to this embodiment will be described.
As shown in FIG. 4, the swing detection means includes two inclinometers 25 and a signal transmitting radio device 13 provided on the deck 8 of the ship 6, and a signal receiving radio provided in the continuous unloader 1. It consists of a device 18 (see FIG. 1). The inclinometer 25 detects the inclination angle of the ship 6, for example, the pitch angle or the roll angle.
　傾斜計２５で検出された船舶６の動きに関する信号は、信号送信用無線装置１３から信号受信用無線装置１８を介して制御部に送られる。そして、検出された信号に基づいて、表示手段に例えばピッチ角、ロール角それぞれの船舶６の動きを波形によって表示する。制御部や表示手段は、例えば連続式アンローダ１のオペレータ室に設置される。船舶６の動きは、波形ではなく、数値やインジケータなどで表示してもよい。 A signal related to the movement of the ship 6 detected by the inclinometer 25 is sent from the signal transmission radio device 13 to the control unit via the signal reception radio device 18. Based on the detected signal, the movement of the ship 6 at each pitch angle and roll angle, for example, is displayed as a waveform on the display means. A control part and a display means are installed in the operator room of the continuous unloader 1, for example. The movement of the ship 6 may be displayed not by a waveform but by a numerical value or an indicator.
　これによって、連続式アンローダ１のオペレータが船舶６の揺動周期を把握することができ、荷役時の掘削手段の操作の手助けとなる。また、無線通信手段を使用することによって、船舶６側と連続式アンローダ１側との信号用配線が不要になる。更に、傾斜計２５は、第１実施形態のレーザ距離計１５、ぶれ検出カメラ１６及びぶれ検出ターゲット１７や、第２実施形態の投光側光電センサ１１及び受光側光電センサ１２と異なり、周囲環境（例えばバラ荷による粉塵）の影響を受けづらく、検出精度が良い。 This makes it possible for the operator of the continuous unloader 1 to grasp the rocking cycle of the ship 6 and to assist the operation of the excavation means during cargo handling. Further, by using the wireless communication means, signal wiring between the ship 6 side and the continuous unloader 1 side becomes unnecessary. Further, the inclinometer 25 is different from the laser distance meter 15, the blur detection camera 16, and the blur detection target 17 of the first embodiment, and the light emitting side photoelectric sensor 11 and the light receiving side photoelectric sensor 12 of the second embodiment. It is difficult to be affected by (for example, dust caused by loose loads) and has good detection accuracy.
［第５実施形態］
　次に、本発明の第５実施形態について、図５～図８を用いて説明する。
　本実施形態は、連続式アンローダ１の本体部４及び掘削手段について、第１実施形態と同様であるため、詳細な説明は省略する。本実施形態は、第１実施形態又は第３実施形態において検出された船舶６の揺動量を用いて、掘削手段の無端状チェーン１０のたるみ量又はバラ荷と掘削手段との距離を変更する操作手段を備える。 [Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described with reference to FIGS.
Since this embodiment is the same as that of 1st Embodiment about the main-body part 4 and excavation means of the continuous unloader 1, detailed description is abbreviate | omitted. In the present embodiment, the amount of sag of the endless chain 10 of the excavation means or the distance between the loose load and the excavation means is changed using the swing amount of the ship 6 detected in the first embodiment or the third embodiment. Means.
　例えば、船舶６の揺動量が小さいときは、図５に示すように、無端状チェーン１０のたるみ量を小さくし、船舶６の揺動量が大きいときは、図６や図７に示すように、無端状チェーン１０のたるみ量を大きくする。これにより、船舶６の揺動量が大きいとき、バケット３とボトムピース３１との間隔を大きくすることができるため、波のうねりが大きいときにバケット３とボトムピース３１との衝突の危険性を低減できる。無端状チェーン１０のたるみ量は、先端スプロケット３２と後端スプロケット３３との間の間隔や位置を変更する油圧シリンダ（図示せず。）によって調節される。 For example, when the amount of swing of the ship 6 is small, as shown in FIG. 5, the amount of sag of the endless chain 10 is reduced, and when the amount of swing of the ship 6 is large, as shown in FIGS. The amount of sag of the endless chain 10 is increased. Thereby, since the space | interval of the bucket 3 and the bottom piece 31 can be enlarged when the rocking | fluctuation amount of the ship 6 is large, when the wave | undulation of a wave is large, the danger of the collision with the bucket 3 and the bottom piece 31 is reduced. it can. The amount of sag of the endless chain 10 is adjusted by a hydraulic cylinder (not shown) that changes the distance and position between the front end sprocket 32 and the rear end sprocket 33.
　または、例えば、船舶６の揺動量が小さいときは、バラ荷とバケット３との平均間隔を小さくし、船舶６の揺動量が大きいときは、バラ荷とバケット３との平均間隔を大きくする。船舶６は常に揺動していることから、バラ荷とバケット３の間隔は時間変化する。ここで平均間隔とは、時間変化するバラ荷とバケット３の間隔の平均間隔である。バラ荷とバケット３が最も近接したときに、バケット３が最も多くバラ荷を掘削できる。 Or, for example, when the swing amount of the ship 6 is small, the average interval between the loose load and the bucket 3 is reduced, and when the swing amount of the ship 6 is large, the average interval between the loose load and the bucket 3 is increased. Since the ship 6 is constantly oscillating, the interval between the loose load and the bucket 3 changes over time. Here, the average interval is an average interval between the time-varying bulk load and the bucket 3. When the bulk load and the bucket 3 are closest, the bucket 3 can excavate the bulk load most.
　例えば図８に示すように、バケット３は深さＡ分又は深さＢ分のバラ荷を掘削する。バラ荷とバケット３との平均間隔が小さければ、バラ荷とバケット３が最も近接したときに、図８の深さＡ分を掘削できる。一方、バラ荷とバケット３との平均間隔が大きいと、バラ荷とバケット３が最も近接したときでも、図８の深さＢ分しか掘削できない。 For example, as shown in FIG. 8, the bucket 3 excavates a bulk load of depth A or depth B. If the average distance between the loose load and the bucket 3 is small, the depth A of FIG. 8 can be excavated when the loose load and the bucket 3 are closest. On the other hand, if the average distance between the bulk load and the bucket 3 is large, even when the bulk load and the bucket 3 are closest to each other, only the depth B in FIG. 8 can be excavated.
　しかし、バラ荷とバケット３との平均間隔を調整することによって、海のうねりが高いとき、船舶６が連続式アンローダ１に衝突するおそれを低減できる。例えば、ボトムピース３１の下側を通過するバケット３が船底や積載されているバラ荷に当たり、更にバケット３が上側に移動することによって、ボトムピース３１に衝突する可能性を低減できる。 However, by adjusting the average distance between the loose load and the bucket 3, the risk of the ship 6 colliding with the continuous unloader 1 when the sea swell is high can be reduced. For example, the possibility that the bucket 3 passing under the bottom piece 31 hits the ship bottom or a bulk load loaded thereon, and further the bucket 3 moves upward, reduces the possibility of colliding with the bottom piece 31.
