WATER GATE OPENING/CLOSING DEVICE
To provide a water gate opening/closing device which can stably lift a door body upward and downward while maintaining its equilibrium state even if the three-phase power supply is lost.SOLUTION: A water gate opening/closing device 1 includes: a pair of opening/closing device bodies 15 that has a hydraulic pressure lifting device 27 connected to a door body 3 opening/closing a water gate 2, adjusting the lifting speed of the door body 3 to lift the door body upward and downward by controlling the supply amount of the hydraulic oil, a hydraulic pump 40 supplying the hydraulic oil to the hydraulic pressure lifting device 27, and an engine 45 provided as the power source of the hydraulic pump 40, and is arranged respectively independently on both sides in the width direction of the door body 3; and a control device 76 which controls the supply amount of the hydraulic oil in each hydraulic pressure lifting device 27 to correct the inclined posture thereof when the width direction of the door body 3 is inclined with respect to the width direction of the water gate 2 during the lifting of the door body 3. With this configuration, the door body 3 can be stably lifted upward and downward while maintaining the equilibrium state thereof even if the three-phase power supply is lost.SELECTED DRAWING: Figure 1
【課題】三相電源を喪失しても、扉体をその平衡状態を維持しながら安定して昇降させることのできる水門開閉装置を提供する。【解決手段】本水門開閉装置１は、水門２を開閉する扉体３に連結され、作動油の供給量を制御することで、扉体３をその昇降速度を調整して昇降させる油圧昇降装置２７と、該油圧昇降装置２７に作動油を供給する油圧ポンプ４０と、該油圧ポンプ４０の動力源として設けられるエンジン４５と、を備えた開閉装置本体１５が、扉体３の幅方向両側にそれぞれ独立して一対配置され、扉体３の昇降中、扉体３の幅方向が水門２の幅方向に対して傾斜した場合、各油圧昇降装置２７における作動油の供給量を制御して、その傾斜姿勢を補正する制御装置７６を備えている。これにより、三相電源を喪失しても、扉体３をその平衡状態を維持しながら安定して昇降させることができる。【選択図】図１
