  • a gatepost slab above said stanchions is provided, said cylinder operating apparatus is arranged on said gatepost slab above said stanchions and said pinion mounting intermediate mount is installed below a cylinder rod of said cylinder operating apparatus.
  • two cylinder operating apparatuses are provided, said cylinder operating apparatuses are installed outside said stanchions on both sides of said gate and said cylinder operating apparatuses and both ends of said pinion mounting intermediate mount are connected by pins.
  • the gate is driven by the movable rack bars meshed with the pinions, and is raised and lowered with the same stroke as that of the cylinder rod raised and lowered by the cylinder.
  • a cylinder stroke of half or less that of the gate lift will suffice, accordingly.

  • a pinion mounting intermediate mount 25 is mounted at the upper parts of the cylinder rods 23 and 24.
  • the pinion mounting intermediate mount 25 is moved up and down by the hydraulic cylinders 21 and 22 while being guided in all directions by a guide roller 41 and a guide shoe 42.
  • Pinions 43 are rotatably provided on both sides of the pinion mounting intermediate mount 25.
  • a stationary rack 44 meshed with the outside of the first pinion 43 is secured to a mount 51 above the stanchions 2 and 3, and the gate 1 is secured to the lower end of a movable rack bar 45 meshed with the insides of the pinion 43.
  • Rollers 46 and 47 are provided outside the stationary rack 44 and the movable rack 45 to prevent them from becoming disengaged from the pinion 43.
  • the external teeth of the pinion 43 are made immovable by means of the stationary rack 44, and the tangential speed of the stationary rack 44 is equal to that of the movable rack 45.
  • the movable rack 45 is also moved up and down at the same speed as the lifting speed of the pinion mounting intermediate mount 25. That is, the movable rack 45 is to be moved up and down by twofold the distance of the stroke of the hydraulic cylinders 21 and 22.
  • the first embodiment is for a gutter gate and a gutter pipe, and is used where water is so deep that the cylinder type operating apparatus will probably be immersed.
  • the second and third embodiments are for a dam, and are used where water is so shallow that the cylinder type operating apparatus does not reach water level.
  • the cylinder rod of the cylinder will suffice if moved up by half a stroke or less of the lift. Therefore, it is not necessary to have a cylinder which is high in buckling resistance and has the same length as that of the lift of the gate. Further, the ceiling of the upper house housing therein will only need be about half the height of the lift. It is not necessary to make the ceiling higher according to the lift of the gate. Thus, the ceiling of the upper house can be lower, and will not obstruct the view.
