Document Type and Number:
Japanese Patent JP2019127790
Kind Code:
A
Abstract:
To provide an opening/closing apparatus for sluice gate that can guide a chain stably to a mechanism supporting the chain.SOLUTION: An opening/closing apparatus for sluice gate 10 winds up a chain 12 provided with an engaging part 11 by means of rotational driving of a drive sprocket 13 and lifts a door body W joined to the chain 12. The opening/closing apparatus for sluice gate 10 includes a decelerating mechanism 18 that has a motor 16 and a first output shaft 27 joined to the center of the drive sprocket 13, and provides driving force of the motor 16 for drive sprocket 13; chain holding means 19 that supports the wound-up chain 12 by the engaging part 11 being hooked to the chain holding means 19; a guide sprocket 46 to which the chain 12 is hooked and that guides the chain 12 to the chain holding means 19; and power transmission means 56 that conveys driving force output from the decelerating mechanism 18 to the guide sprocket 46 to rotate the guide sprocket 46. The decelerating mechanism 18 has a second output shaft 26 providing driving force for power transmission means 56.SELECTED DRAWING: Figure 1
