項記載の転倒堰の巻上げ装置。[Scope of Claim for Utility Model Registration] (1) A hoisting device that suspends and supports a weir plate with a water channel that can be tipped over and raised up using wire, in which a pulley that winds up the wire can be rotated only in the hoisting direction. It is connected via a gear train to a hoisting shaft provided with a rotation restraint means, and one gear constituting the gear train functions as a first cam that works in conjunction with a detection device such as a float that detects the water level of the waterway. When the water level is lower than the first set water level, the gear maintains the meshing relationship with other adjacent gears, but when the water level rises higher than this, the gear rotates to disengage the gear. The other gear that is attached to the first swing frame and that constitutes the gear train is provided with a cam wheel that has an engaging portion on its outer periphery and rotates integrally with the gear, and this cam wheel A second swing frame is provided that faces the cam wheel and has an engagement tool that engages with the engagement portion of the cam wheel, and the second swing frame is configured to engage the second cam that interlocks with the detection tool. When the water level rises above a predetermined value due to the action, the engaging part and the engaging tool are disengaged, and the water level becomes lower than a second set water level that is lower than the first water level. 1. A hoisting device for an overturning weir, characterized in that the device is provided so that when the two gears are engaged, the rotation of the gear train is stopped. (2) The first cam and the second cam are connected to each other by a connecting device such as a chain so that they move together in the direction of restraining the rotation of the pulley, but move independently in the direction of releasing the restraint. Scope of claim for utility model registration No. 1
A hoisting device for an overturning weir as described in Section 1.
