PROBLEM TO BE SOLVED: To provide a low cost sluice gate opening and closing device in which a looseness overload detection device is not enlarged even if an opening/closing load is large, and an expensive chain is not elongated.SOLUTION: A sluice gate opening and closing device includes a looseness overload detection device 13 for detecting a looseness and overload of a chain 12 by measuring a tensile change acting on the chain 12 to lift and lower a door 2 based on the movement of a detecting rod 27. The sluice gate opening and closing device has a chain support beam 53 for swingably supporting one end of the chain 12 through a chain connecting rod 51, and is provided with a chain terminal mechanism 50 having one end of the chain support beam 53 supported turnably and the other end connected to the detecting rod 27. A detection load of the looseness overload detection device 13 is reduced even if an opening/closing load is large. A portion of one end side of the chain 12 is replaced with the rod 51, and a chain length is reduced.
【課題】開閉荷重が大きくても、緩み過負荷検出装置は大きくならず、また高価なチェーンを長くせず、安価な水門開閉装置を提供できる。【解決手段】扉体２を昇降させるチェーン１２に作用する張力の変化を検出ロッド２７の移動に基づき計測してチェーン１２の緩み及び過負荷を検出する緩み過負荷検出装置１３を備えた水門開閉装置において、チェーン１２の一端をチェーン連結ロッド５１を介して揺動自在に支持するチェーン受梁５３を有し、チェーン受梁５３の一端は回動自在に支持され、他端は検出ロッド２７に連結されてなるチェーン端末機構５０を設ける。開閉荷重が大きくても緩み過負荷検出装置１３の検知荷重を小さくする。チェーン１２の一端部側の一部をロッド５１に置換え、チェーン長を削減する。【選択図】図１
