MECHANICAL OPENING/CLOSING BODY STOP DEVICE OF SWITCHGEAR
PROBLEM TO BE SOLVED: To provide a mechanical opening/closing body stop device of a switchgear for stopping closing movement when an opening/closing body in the closing movement abuts on an obstacle.SOLUTION: A mechanical opening/closing body stop device of a switchgear includes: brake means which can stop and move a shutter curtain being an opening/closing body by being turned on and off; a slide member which slides for on/off-switching the brake means; and mechanical lock means 68 which is arranged at the shutter curtain, mechanically brings a chain 35 being a string-like member into a lock state with respect to the shutter curtain at the abutment of a seat plate on the obstacle, and makes a tension force which turns on the brake means by making the slide member slide act on the chain 35 by the own weight of the shutter curtain. The means 68 has a ratchet member 66 which oscillates with a pivot shaft 67 as a center, and a ratchet wheel 65 having a claw part in which a claw part 66D of the ratchet member 66 bites. The claw part 66D of the ratchet member 66 is arranged at an end part of the ratchet member 66 in a longitudinal direction.
【課題】閉じ移動中の開閉体が障害物に当接したときにこの閉じ移動を停止させるための開閉装置の機械式開閉体停止装置を提供する。【解決手段】オン、オフして開閉体であるシャッターカーテンを停止、移動可能とするブレーキ手段と、ブレーキ手段をオン、オフ切り替えるためにスライドするスライド部材と、シャッターカーテンに配置され、座板の障害物への当接時にシャッターカーテンに対して紐状部材であるチェーン３５を機械式にロック状態とし、チェーン３５に、スライド部材をスライドさせてブレーキ手段をオンとする緊張力をシャッターカーテンの自重で作用させる機械式ロック手段６８とを含み、手段６８は、支点軸６７を中心に揺動運動するラチェット部材６６と、ラチェット部材６６の爪部６６Ｄが噛み込む爪部を有するラチェットホイール６５を有し、ラチェット部材６６の爪部６６Ｄはラチェット部材６６の長さ方向の端部に設けられている。【選択図】図９
