Abstract:
To provide an apparatus for opening and closing sluice gate that can prevent a chain or a wire from dropping in a state where a drive unit and a driven unit are not linked by an interlock shaft.SOLUTION: An apparatus for opening and closing sluice gate 10 includes a drive unit 12 having a motor 11, a driven unit 13, and an interlock shaft 14 that is driven rotationally by the motor 11 to transmit drive force of the motor 11 to the driven unit 13, the apparatus for opening and closing sluice gate 10 lifting and lowering a door body 17 hung by linear members 15, 16. The drive unit 12 includes a rotary body 20 on which the linear member 15 is locked and that is driven rotationally by being given drive force of the motor 11. The driven unit 13 includes an input shaft 22 which is driven rotationally with the interlock shaft 14 in a state of being connected to the interlock shaft 14, and a rotary body 23 on which the linear member 16 is locked and that is driven rotationally by being given drive force of the motor 11 via the interlock shaft 14 and the input shaft 22. A fastening mechanism 42 is attached on the driven unit 13, the fastening mechanism 42 fastening the input shaft 22 to bring the rotary body 23 into a standstill.SELECTED DRAWING: Figure 2
