FLOODGATE OPENING/CLOSING DEVICE
To provide a floodgate opening/closing device capable of lowering a door body at a higher speed than ascending without changing the rotation speed of a motor.SOLUTION: In a floodgate opening/closing device 10 having a power transmission mechanism 13 in which an output unit 12 is rotationally driven by the rotational force of a drive source 11 and raising and lowering a door body G of the floodgate at a speed corresponding to the rotational drive of the output unit 12, the drive source 11 includes first and second motors 14 and 15. In the power transmission mechanism 13, the rotational force of the first motor 14 rotating in a T1 direction and the rotational force of the second motor 15 rotating in an R1 direction are input to input units 17 and 23 corresponding to the first and second motors 14 and 15, respectively. The output unit 12 is rotationally driven in one direction at rotation speed S1 to lower the door body G. While the rotational force of the second motor 15 is not input to the input unit 23, the rotational force of the first motor 14 rotating in the T2 direction is input to the input unit 17. The output unit 12 is rotationally driven in the other direction at rotation speed S2 smaller than the rotation speed S1 to raise the door body G.SELECTED DRAWING: Figure 1
【課題】モータの回転数を変えずに扉体の下降を上昇より高速に行うことが可能な水門開閉装置を提供する。【解決手段】駆動源１１の回転力が与えられて出力部１２が回転駆動する動力伝達機構１３を有し、出力部１２の回転駆動に応じた速度で水門の扉体Ｇを昇降する水門開閉装置１０において、駆動源１１は第１、第２のモータ１４、１５を具備し、動力伝達機構１３は、第１、第２のモータ１４、１５にそれぞれ対応する入力部１７、２３に、Ｔ１方向に回転している第１のモータ１４の回転力及びＲ１方向に回転している第２のモータ１５の回転力がそれぞれ入力されて、出力部１２が回転数Ｓ１で一方向に回転駆動し扉体Ｇを下降させ、第２のモータ１５の回転力が入力部２３に非入力の状態で、Ｔ２方向に回転している第１のモータ１４の回転力が入力部１７に入力されて、出力部１２が回転数Ｓ１より小さい回転数Ｓ２で他方向に回転駆動し扉体Ｇを上昇させる。【選択図】図１
