SLUICE GATE OPENING/CLOSING DEVICE
To provide a sluice gate opening/closing device that can make a door body drop using its own weight stably while maintaining the balanced state of the door body.SOLUTION: An opening/closing device body 15 has a self-weight drop control device 27 that applies the brakes to the self-weight drop of a door body 3 when the door body 3 is made to drop using its own weight and adjusts the self-weight drop speed. The self-weight drop control device 27 has an adjustment part 44 that changes braking forces with respect to the self-weight drop of the door body 3 by rotating on its axis. A synchronization mechanism 16 includes: a pair of rotary bodies 60, 61 that each rotate together with lifting and lowering both sides of the door body 3 in the width direction; and a differential gear 62 that has an output shaft 63 rotating, when a difference arises between the rotation phases of the rotary bodies 60, 61, on its axis depending on the rotation phase difference. The output shaft 63 of the differential gear 62 and the adjustment part of the self-weight drop control device 27 are connected.SELECTED DRAWING: Figure 1
【課題】扉体をその平衡状態を維持しながら安定して自重降下させることのできる水門開閉装置を提供する。【解決手段】開閉装置本体１５は、扉体３を自重降下させる際に扉体３の自重降下を制動して自重降下速度を調整する自重降下制動装置２７を有しており、自重降下制動装置２７は、軸周りに回転することにより扉体３の自重降下に対する制動力を変更する調整部４４を有している。同調機構１６は、扉体３の幅方向両側における昇降に伴ってそれぞれ回転する一対の回転体６０、６１と、回転体６０、６１の回転位相に差が生じた場合に、その回転位相差に応じて軸周りに回転する出力軸６３を有する差動ギヤ６２とを備えており、差動ギヤ６２の出力軸６３と自重降下制動装置２７の調整部とが連結されている。【選択図】図１
