The present invention relates to an emergency drum brake system for a stage facility. The emergency drum brake system for a stage facility comprises a drum (3) installed to unwrap a plurality of wire ropes, which are connected to the batons of the stage facility, so that the plurality of wire ropes are wound to pull the same or are lowered, a motor (4) for driving the rotating shaft (2) of the drum, and a reducer (5). The emergency drum brake system for a stage facility, for preventing the drum (3) from being rotated unintentionally out of a preset condition, further comprises: an emergency brake (20) having a brake member (24) which is mounted on a base plate (21) installed adjacent to at least one end of the drum and is raised and lowered to a braking position in which the brake member comes in close contact with the surface of the drum by a solenoid (22) and a release position in which the brake member is separated from the surface of the drum. Therefore, the emergency drum brake system for a stage facility can reduce manufacturing costs with a simplified configuration, can quickly stop the fall or excessive rise of stage facilities, backdrops, and lighting fixtures connected to the wire ropes and having the batons, thereby preventing accidents, and can be easily mounted even on a drum for an existing stage facility.
본 발명은 무대시설용 드럼 비상브레이크장치에 관한 것으로, 무대시설의 바튼들에 연결된 다수의 와이어로프들을 견인하기 위해 감거나 하강시키도록 와이어로프를 풀기 위해 설치된 드럼(3)과, 드럼의 회전축(2)을 구동시키기 위한 모터(4), 감속기(5)를 구비하는 드럼장치에서, 상기 드럼(3)이 의도하지 않게 미리 설정된 조건에서 벗어난 상태로 회전되는 것을 방지하기 위한 무대시설용 드럼 비상브레이크장치에 있어서, 드럼의 적어도 일측 단부에 인접하게 설치된 베이스플레이트(21)에 장착되고 솔레노이드(22)에 의해 드럼 표면에 밀착되는 제동위치와, 드럼 표면에서 분리된 해제위치로 승하강되는 브레이크부재(24)를 구비하는 비상 브레이크(20)를 포함하는 것을 특징으로 하여 구성됨으로써, 단순화된 구성으로 제조비용을 저감시킬 수 있고, 와이어로프들에 연결된 바튼 장착된 무대시설, 배경막들, 조명기들의 추락이나 과도한 상승을 신속하게 정지시킬 수 있게 되으므로 안전사고 발생을 방지할 수 있고, 기존의 무대시설용 드럼에도 간편하게 장착할 수 있는 효과가 있다.
