本考案はリフティングビームの昇降によってフックを開
閉させ自動的にゲートの係脱しうるようにした装置に関
するもので、その目的とするところは簡単な操作によっ
て確実に係脱することができる装置を提供しようとする
ものである。[Detailed description of the invention] This invention relates to a device that automatically engages and disengages the gate by opening and closing the hook by raising and lowering the lifting beam.The purpose of this invention is to securely engage and disengage the gate with a simple operation. The aim is to provide a device that can do this.
以下本考案を図示の実施例に基づいて詳細に説明する。The present invention will be explained in detail below based on the illustrated embodiments.
１はゲートＡを懸吊するリフティングビーム、２はリフ
テンビーム１の内部中央に架設した軸イに基端を回転自
在に枢着し、先端にブツシュロッド３を枢着したアーム
で、その基端部には後述する主爪車５と噛合う爪片４が
枢着されている。1 is a lifting beam for suspending the gate A; 2 is an arm whose base end is rotatably pivoted to a shaft A built in the center of the interior of the liften beam 1; a bushing rod 3 is pivotally attached to the tip; A pawl piece 4 that meshes with a main pawl wheel 5, which will be described later, is pivotally mounted.
このブツシュロッド３は常時リフティングビーム１の下
方に吊下突出している。This bushing rod 3 is always suspended and protrudes below the lifting beam 1.
５は軸イ楔着された生爪車、６は軸イに楔着された副爪
車で、リフティングビーム１の適所に枢着した爪片７と
噛合うようになっている。Reference numeral 5 denotes a permanent pawl wheel which is wedge-attached to the shaft A, and numeral 6 denotes an auxiliary pawl wheel which is wedge-attached to the axle I, which are designed to mesh with the pawl pieces 7 which are pivoted at appropriate positions on the lifting beam 1.
８は軸イに楔着した楕円形カム、９はリフティングビー

共に両端を左右のフック９，９に連結したワイヤロープ
、１１はリフティングビーム１を懸吊するワイヤロープ
、１２はゲートＡに取付けた吊り金具、１３は重錘、１
５はゲートＡの受台である。8 is an oval cam wedged on the shaft A; 9 is a hook rotatably suspended through narrow openings on both the left and right sides of the lifting beam 1; 10 is a hook whose central portion touches the outer periphery of the elliptical cam 8, and at both ends; are connected to the left and right hooks 9, 9, 11 is a wire rope for suspending the lifting beam 1, 12 is a hanging fitting attached to gate A, 13 is a weight, 1
5 is a pedestal for gate A.
本考案は上記の構成からなり、リフティングビーム１に

図に示すように、ワイヤロープ１１を巻戻してリフティ
ングビーム１とこれに懸吊したゲートＡがドツキングし
た状態で下降させゲ−）Ａが定位置の受台１５上に到達
した時点で一旦巻戻しを停止する。The present invention has the above-mentioned configuration, and in order to set the gate A pulled up by the lifting beam 1 to the spout B, the third
As shown in the figure, the wire rope 11 is unwound and the lifting beam 1 and the gate A suspended thereon are lowered in a docked state. Stop reverting.
次にワイヤロープ１１をさらに巻戻してリフティングビ

線の状態から点線の状態となり該楕円形カム８に接して
いるワイヤロープ１０を拡開するため左右のフック９，
９は外側に回動し吊り金具１２から外れるのである。Next, when the wire rope 11 is further unwound and only the lifting beam 1 is lowered, the lower end of the bushing rod 3 protruding below the lifting beam 1 hits the upper surface of the gate A and is pushed up, causing the upper end of the bushing rod 3 to pivot. The attached arm 2 is rotated clockwise, and the pawl piece 4 pivotally attached to the base end of the arm 2 is wedged on the shaft A together with the main pawl wheel 5 in order to rotate the main pawl wheel 5 by the rotation angle of the arm 2. The secondary ratchet wheel 6 and the oval cam 8 also rotate, and the oval cam 8 changes from the state shown by the solid line in FIG. 1 to the state shown by the dotted line in FIG. 9,
9 rotates outward and comes off from the hanging fitting 12.
次にワイヤロープ１１を巻上げるとリフティングビーム
１のみが上昇するためアーム２はブツシュロッド３の自
重により第１図に示すように元の実線の位置に戻り該ア
ーム２の作動に伴って爪片４も主爪車５の外周を摺動し
てて元の位置に戻るのである。Next, when the wire rope 11 is wound up, only the lifting beam 1 rises, so that the arm 2 returns to the original solid line position due to the weight of the bushing rod 3, as shown in FIG. It also slides on the outer periphery of the main ratchet wheel 5 and returns to its original position.
この場合爪片７は副爪車６と噛合ったま）軸イの逆回転
を防止している。In this case, the pawl piece 7 is engaged with the auxiliary pawl wheel 6 and prevents the shaft I from rotating in the opposite direction.
従ってリフティングビーム１は第１図において楕円形カ

動するのである。Therefore, the lifting beam 1 has the oval cam 8 and the wire rope 10 in the dotted line position in FIG.
, 9 are opened, the arm 2 and bushing rod 3 are raised to the position shown by the solid line), and the above operation is repeated to operate the other water gates.

作が容易かつ確実となる。Therefore, the oval cam 8 and the wire rope 10 are
Since the hook 9 is only hooked so that the wire rope 10 is in contact with the top surface, the hook 9 is constantly engaged and operated repeatedly as the cam 8 rotates, resulting in idle operation. There is no need to perform unnecessary operations such as , and therefore the operation becomes easy and reliable.
なお、リフティングビーム１と運転しない時はブツシュ
ロッド３をアーム２との枢着点から反時計方向に略水平
に屈曲してビーム１内に格納しておく。When not operating with the lifting beam 1, the bushing rod 3 is bent approximately horizontally counterclockwise from the pivot point with the arm 2 and stored in the beam 1.
またフック９，９間を連結しているワイヤロープ１０は
、図面に示すように両端にロッド１４を介在させること

うになっているが、ワイヤロープ１０のみで連結しても
よい。Further, the wire rope 10 connecting the hooks 9, 9 has rods 14 interposed at both ends as shown in the drawing, so that the amount of movement of the hook 9 can be increased. The connection may be made using only the rope 10.

簡単な構造によりゲートとリフティングビームとの係脱
を無動力で、しかも自動的に行なうことができる。As described above, in this invention, an elliptical cam, a main ratchet wheel, and a auxiliary ratchet wheel are wedged on the shaft installed in the center of the interior of the lifting beam, and the base end of the arm, which has a bushing rod pivoted at the tip, can be freely rotated. A pawl piece that engages with the main ratchet wheel is pivotally attached to the arm, a pawl piece that engages with the secondary ratchet wheel is pivotally attached to the appropriate position of the beam, and hooks suspended on the left and right sides of the beam are pivotally attached to the arm. The oval cam is sandwiched between the connecting wires, and the hook is opened and closed by rotation of the oval cam.
With a simple structure, the gate and lifting beam can be engaged and disengaged without power and automatically.
また、楕円形カムを回動して係脱を交互に繰返すことに
よってゲートの角落しを行なうことができるので、作業
員が目視することのできない水中での係脱も容易かつ確
実である等産業上有益な考案である。In addition, by rotating the oval cam and repeating engagement and disengagement, it is possible to drop the corner of the gate, making it easy and reliable to engage and disengage underwater, where workers cannot visually see. This is a very useful idea.
