PROBLEM TO BE SOLVED: To provide an opening/closing body switchgear that has a simple structure and prevents an opening/closing body from falling down suddenly.SOLUTION: An opening/closing body switchgear comprises: an opening/closing body for making an aperture of an aperture member be in the open state or in the closed state, the opening/closing body having mass acting in the closing direction; a plurality of drive units for making the opening/closing body be in the opening direction and closing direction; an opening/closing control unit for controlling the plurality of drive units; and a detection unit for detecting motions of the plurality of drive units. The opening/closing control unit, using a signal from the detection unit, monitors drive states of the plurality of drive units; and, when it is determined that each of the drive units is in an individually abnormal state, individually abnormal, in the case of the opening/closing body's movement by the drive units or the opening/closing body's stoppage in the open state, performs restriction control of restricting movement in the opening/closing body's closing direction on the individually abnormal drive unit and, when it is determined by comparing the drive unit on which the restriction control is preformed with the other drive unit's drive state that the drive units are relatively normal, determines that the opening/closing body is in the normal state before releasing the restriction control.SELECTED DRAWING: Figure 6
【課題】簡単な構造で開閉体の急落下を防止する開閉体開閉装置を提供する。【解決手段】開口部材の開口部を開状態または閉状態とする、質量が閉方向に作用する開閉体と、開閉体を開方向と閉方向に移動させる複数の駆動部と、複数の駆動部を制御する開閉制御部と、複数の駆動部の動作を検知する検知部とを備える。開閉制御部は、検知部からの信号により複数の駆動部の駆動状態を監視し、開閉体の前記駆動部による移動の際または前記開閉体が開状態で停止している際に、駆動部のそれぞれが、単独で異常状態である単独異常と判断された場合に、単独異常の駆動部に対して、開閉体の閉方向への移動を規制する規制制御をし、規制制御された駆動部と他の駆動部の駆動状態を比較して、これらの駆動部が相対して正常であると判断された場合は、開閉体が正常状態であるとして規制制御を解除する。【選択図】図6
