GATE DRIVING DEVICE IN SELF-WEIGHT DESCENDING TYPE GATE FACILITY
To prevent reduction in a gate descending speed due to an idling of a motor.SOLUTION: A gate driving device 1 is used for a self-weight descending type gate facility 10 comprising a gate driving shaft 12 elevating and lowering a gate 11, and descending state changing means 13 for changing a descending state between a non-self-weight descending state in which the gate 11 does not descend by self-weight and a self-weight descending state in which the gate descends by self-weight. The gate driving device comprises: a motor 2; and a clutch mechanism 3 interposed between a motor output shaft 2a of the motor 2 and the gate driving shaft 12. The clutch mechanism 3 includes: a one-way clutch 5 transmitting only the torque in a descending direction between the motor output shaft 2a and the gate driving shaft 12; a bypass clutch 6 which is arranged together with the one-way clutch 5, which bypasses the one-way clutch 5 in a connection, and which transmits both of a torque in an ascending direction and a torque in a descending direction between the motor output shaft 2a and the gate driving shaft 12; and bypass clutch changing means 7 which changes between the connection and the release of the bypass clutch 6.SELECTED DRAWING: Figure 2
【課題】 原動機の空転によるゲート降下速度の低下を防ぐ。【解決手段】 ゲート駆動装置１は、ゲート１１を昇降駆動するゲート駆動軸１２と、該ゲート１１が自重で降下しない非自重降下状態又は同降下する自重降下状態に切り替える降下状態切替手段１３とを備える自重降下式ゲート設備１０におけるものであり、原動機２と、該原動機２の原動機出力軸２ａ及びゲート駆動軸１２の間に介装されるクラッチ機構３とを備えている。クラッチ機構３は、降下方向へのトルクのみを原動機出力軸２ａ及びゲート駆動軸１２の間で伝動するワンウェイクラッチ５と、該ワンウェイクラッチ５に併設され、連結時に該ワンウェイクラッチ５をバイパスさせて、上昇方向及び降下方向の両方向へのトルクを原動機出力軸２ａ及びゲート駆動軸１２の間で伝動するバイパスクラッチ６と、該バイパスクラッチ６の連結又は解放を切り替えるバイパスクラッチ切替手段７とを備えている。【選択図】 図２
