WATER GATE OPEN/CLOSE DEVICE AND HYDRAULIC DRIVE UNIT
To provide a water gate open/close device which can ensure safety even when a motor for lifting a door body has a failure.SOLUTION: A water gate open/close device 1 is provided with: a hydraulic motor 15 connected to a door body 3 and lifting the door body 3; hydraulic sources 16a and 16b including pumps 33a and 33b and motors 34a and 34b driving the pumps to allow control of a discharge rate and a discharge direction; a first close circuit 17 connecting the hydraulic motor 15 and the pumps 33a and 33b; and fail-safe means 23 for limiting fall of the door body 3 by its own weight when the hydraulic sources 16a and 16b are inoperable and limitation of a rotating shaft 15 of the hydraulic motor 15 is released. Consequently, safety is ensured by limiting rapid fall of the door body 3 by its own weight even when the motors 34a and 34b for lifting the door body have failure.SELECTED DRAWING: Figure 1
【課題】扉体昇降用の電動機が故障した場合であっても、安全性を確保できる水門開閉装置を提供する。【解決手段】水門開閉装置１は、扉体３に連結されて、該扉体３を昇降させる油圧モータ１５と、ポンプ３３ａ、３３ｂ及び該ポンプを駆動する電動機３４ａ、３４ｂを含み、吐出量及び吐出方向を制御可能な油圧源１６ａ、１６ｂと、油圧モータ１５とポンプ３３ａ、３３ｂとを連通する第１閉回路１７と、油圧源１６ａ、１６ｂが作動不能で、且つ油圧モータ１５の回転軸１５ａの拘束が解放された際、扉体３の自重落下を規制するフェイルセーフ手段２３と、を備える。これにより、扉体昇降用の電動機３４ａ、３４ｂが故障した場合であっても、扉体３の急激な自重落下を抑制して、安全性を確保することができる。【選択図】図１
