FLOATING BODY-TYPE ROOF GATE
To forcibly raise a door body without applying unbalanced load to a door body.SOLUTION: A floating body-type roof gate 1 comprises: a door body 10 rotating to rise by buoyance generated by infiltrating water; and a forcible raising mechanism 40 having two wire ropes 41 whose one ends are connected to both ends in a width direction of the door body 10 and two fixed pulleys 42 around which each of the two wire ropes 41 is wound, and forcibly raising the door body 10 by pulling the other ends of the two wire ropes 41. The forcible raising mechanism 40 further comprises: two pulley blocks 43 turning each of the two wire ropes 41 so that the other end of the wire rope 41 extending from the fixed pulley 42 goes toward the center in a width direction of the door body 10; and a chain block 44 having two hooks 44b, 44c to which the other end of each of the two wire ropes 41 is connected and a hand chain 44e bringing the two hooks 44b, 44c close to each other.SELECTED DRAWING: Figure 12
【課題】扉体に偏荷重を作用させることなく扉体を強制起立させる。【解決手段】浮体式起伏ゲート１は、浸入水によって生じる浮力によって回動し起立する扉体１０と、一端が扉体１０の幅方向両端部に連結される２本のワイヤロープ４１、２本のワイヤロープ４１のそれぞれが巻き掛けられる２つの定滑車４２を有し、２本のワイヤロープ４１の他端を引っ張ることによって扉体１０を強制起立させる強制起立機構４０とを備える。強制起立機構４０は、定滑車４２から延びるワイヤロープ４１の他端が扉体１０の幅方向中央に向かうように２本のワイヤロープ４１のそれぞれを転向させる２つの滑車ブロック４３と、２本のワイヤロープ４１のそれぞれの他端が連結される２つのフック４４ｂ，４４ｃ、２つのフック４４ｂ，４４ｃを互いに接近させるハンドチェーン４４ｅを有するチェーンブロック４４とをさらに有する。【選択図】図１２
