【考案の詳細な説明】
この考案は、伸縮シユート用のワイヤロープの
緊張装置に関するものである。[Detailed Description of the Invention] This invention relates to a wire rope tensioning device for a telescopic chute.
一般にローダ或はアンローダ等により船或はバ
ージ等からバラ物を荷役する場合、荷受側が波等
の影響で変動するのは不可欠であるため、シユー
トをこの変動に追従させるために伸縮シユートを
介して被荷役物を荷受側或は荷渡側まで案内する
方法が採られている。 Generally, when loading and unloading bulk goods from a ship or barge using a loader or unloader, it is essential that the receiving side fluctuates due to the influence of waves, etc., so in order to make the chute follow this fluctuation, it is necessary to use a telescopic chute. A method is adopted in which the cargo is guided to the receiving side or the unloading side.
ところが、伸縮シユートはその自己追従作用を
有するが、これを吊持するワイヤロープには自己
追従作用がないため、ワイヤロープは変動に応じ
て巻上げ、巻下げを行なわないとたるんだワイヤ
ロープが他の機器にひつかかり機器を破損したり
シユートの巻上げ、巻下げを不可能にする等の不
具合を免れない。 However, although the telescopic chute has a self-following function, the wire rope that suspends it does not have a self-following function, so if the wire rope is not hoisted and lowered according to fluctuations, the slack wire rope will be left behind. It is inevitable that the chute will get caught in the equipment, causing damage to the equipment or making it impossible to hoist or lower the chute.
このため、従来は運転者がワイヤロープのたる
みを見知し巻上機を操作したり、或はワイヤロー
プのたるみを電気的に検知し巻上機を制御するこ
とによりワイヤロープをたるみのない状態に保持
しているのが実状であるが、前者においては、常
時運転者がたるみ具合を見知し巻上機を操作する
ため自動化、省力化が困難であると共に、船倉等
見え難い所の作業は感にたよるしかなく所期の目
的を十分達成することができない。また、後者に
おいては高価な電気制御装置を必要とする欠点を
免れなかつた。 For this reason, in the past, the operator detected slack in the wire rope and operated the hoisting machine, or electrically detected the slack in the wire rope and controlled the hoisting machine to prevent the wire rope from sagging. However, in the former case, it is difficult to automate and save labor because the operator always detects the degree of sagging and operates the hoisting machine, and it is difficult to automate and save labor in hard-to-see places such as holds. You can only rely on your intuition when working, and you will not be able to fully achieve your intended purpose. Furthermore, the latter has the disadvantage of requiring an expensive electric control device.
この考案は上記に鑑みてなされたものであつ
て、簡単かつ安価な構造にして上記の不具合を解
決したものである。 This invention was made in view of the above, and is an attempt to solve the above-mentioned problems by providing a simple and inexpensive structure.
以下、図面に示した実施例に沿い説明する。１
はガーダで、一端に伸縮シユート２を垂下支持す

用巻上機３が装着されている。 The following will explain the embodiments shown in the drawings. 1
is a girder which suspends and supports the telescopic chute 2 at one end, and is equipped with a hoist 3 for hoisting a wire rope for suspending the telescopic chute.
４，４′は一対の重錘案内で一端を夫々ガーダ
に装着されると共に、該案内の上部と下部にはリ
ミツトスイツチ５，５′を装備したストツパー
６，６′が設けられている。 Numerals 4 and 4' are a pair of weight guides, one end of which is attached to the girder, and stoppers 6 and 6' equipped with limit switches 5 and 5' are provided at the upper and lower parts of the guides.
７は重錘で、前記重錘案内４，４′に案内され
ストツパー６，６′の範囲内で上下動する。 A weight 7 is guided by the weight guides 4, 4' and moves up and down within the range of the stoppers 6, 6'.
８，８′はワイヤロープで一端を前記巻上機３

上部に装着したシーブ９，９′及び伸縮シユート
側フランジ１０に装着したシーブ１１，１１′を
介して重錘７に装着されている。 8 and 8' are wire ropes with one end connected to the hoisting machine 3.
and is attached to the weight 7 via sheaves 9, 9' whose other ends are attached to the upper part of the telescopic chute 2 of the girder 1, and sheaves 11, 11' which are attached to the flange 10 on the telescopic chute side.
１２は荷受口で、一端に装着した荷受（渡）口
側フランジ１３と前記伸縮シユート側フランジ１

る。 Reference numeral 12 denotes a cargo receiving port, which includes a cargo receiving (transfer) port side flange 13 attached to one end and the telescopic chute side flange 1.
0 and is connected to the telescopic chute 2.
１４，１４′は伸縮シユート２に装着したワイ
ヤロープガイドである。 14 and 14' are wire rope guides attached to the telescopic chute 2.
この考案は以上の様な構成である。 This idea has the structure described above.
次にその作用を説明する。 Next, its effect will be explained.
予め重錘７の重量はワイヤロープ８，８′の緊
張に十分な重量に設定しておく。 The weight of the weight 7 is set in advance to a weight sufficient to tension the wire ropes 8, 8'.
荷役作業に際しては、伸縮シユート１０と荷受
（渡）口側フランジ１３とは、第２図に示す状
態、即ち、分離されており、ワイヤロープ８，
８′には伸縮シユート２の全重量が負荷されてい
る。 During cargo handling work, the telescopic chute 10 and the cargo receiving (transportation) side flange 13 are in the state shown in FIG. 2, that is, separated, and the wire rope 8,
8' is loaded with the entire weight of the telescopic chute 2.
この伸縮シユート２の重量はワイヤロープ８，
８′の緊張に十分な程度に設定されており重錘７
の重量より重いため、重錘７は上側ストツパー６
に接触するまで上昇する。 The weight of this telescopic chute 2 is wire rope 8,
The setting is sufficient for the tension of 8', and the weight 7
The weight 7 is heavier than the upper stopper 6.
rise until it touches the
この状態から巻上機３を巻下げ伸縮シユート２
が荷受（渡）口側フランジ１３に至るまで巻下げ
ると伸縮シユート２の自重は荷受（渡）口に負担
される。 From this state, lower the hoisting machine 3 and open the telescopic chute 2.
When the telescopic chute 2 is rolled down until it reaches the flange 13 on the cargo receiving (transfer) port side, the weight of the telescopic chute 2 is borne by the cargo receiving (transfer) port.
この状態で伸縮シユート側フランジ１０と荷受
（渡）口側フランジ１３とを連結する。しかる後
更に巻上機３を巻下げると伸縮シユート２がたる
むと共に重錘７は上側ストツパー６から下離れし
第３図に示す如く、ストツパー６，６′の中間ま
で下降する。この時、ワイヤロープ８，８′は重
錘７により引張られ緊張状態を保持する。 In this state, the telescopic chute side flange 10 and the loading/unloading port side flange 13 are connected. Thereafter, when the hoisting machine 3 is further lowered, the telescopic chute 2 becomes slack and the weight 7 moves downwardly away from the upper stopper 6 and descends to the middle of the stoppers 6 and 6' as shown in FIG. At this time, the wire ropes 8, 8' are pulled by the weight 7 and maintained in a tensioned state.
以上説明した工程で荷役作業準備は終り、かか
る状態で巻上機３を停止し荷役作業を開始する。 Preparation for the cargo handling operation is completed through the steps described above, and in this state, the hoisting machine 3 is stopped and the cargo handling operation is started.
荷役中、荷受（渡）側の変化に追従して伸縮シ
ユートも変化（伸縮）するが、ワイヤロープ８，
８′は重錘７がストツパー６，６′間にある間は重
錘の作用により常時緊張状態に保持されている。 During cargo handling, the telescopic chute also changes (expands and contracts) following the changes on the receiving (delivery) side, but the wire rope 8,
8' is always kept under tension by the action of the weight 7 while it is between the stoppers 6 and 6'.
荷役作業中、荷役作業の進捗具合、或は荷受
（渡）側の状況変化によつて重錘の位置は変動昇
降し、上側或は下側ストツパーに当るとリミツト
スイツチ５或は５′が作動し異常変位を検知する
ので、巻上機３を操作し、再度重錘７をストツパ
ー６，６′の略中間に調整し、再度前記同様の工
程で荷役作業を行なう。 During loading and unloading operations, the position of the weight fluctuates and rises and falls depending on the progress of the loading and unloading operations or changes in the situation on the receiving (transferring) side. When it hits the upper or lower stopper, the limit switch 5 or 5' is activated to detect the abnormal displacement. Then, the hoist 3 is operated and the weight 7 is again adjusted to approximately the middle of the stoppers 6, 6', and the loading and unloading operations are carried out again using the same process as described above.
なお、重錘７の調整位置は必ずしもストツパー
６，６′の中間とする必要はなく、作業状況によ
つて重錘７が上昇或は下降することが予想される
場合、予め重錘７のセツト位置を下方或は上方に
しておくことにより再調整間隔を長くすることが
可能であることはいうまでもない。 Note that the adjustment position of the weight 7 does not necessarily need to be between the stoppers 6 and 6', and if the weight 7 is expected to rise or fall depending on the work situation, the adjustment position of the weight 7 may be adjusted in advance. It goes without saying that the readjustment interval can be made longer by keeping the position lower or higher.

装置も必要としない等の効果を有する。 As mentioned above, according to this invention, it is possible to tension the wire rope for hoisting a telescopic chute, which is essential in cargo handling work using a telescopic chute, using an extremely simple and inexpensive device, which facilitates operation. In addition, there is an advantage that a complicated and expensive electric control device is not required.
