The present invention provides a safety assistant device which promptly warns when a worker working in a power transmission tower enters an area with hazard, such as an electric shock and the like, for maintenance of overhead distribution lines in a live wire state to prevent an accident. In particular, the safety assistant device comprises: a case formed in the shape of a hollow housing and including two bodies capable of being separated and coupled to each other by a fastening means, and having a control unit disposed therein; and a roller member rotatably provided inside the case and having a wire disposed on the outer surface to be connected to work clothes and be wound, wherein different detection switches are electrically connected to each other during rotation so that winding length of the wire is determined through the control unit, thereby informing a worker of whether or not to enter a hazardous area. The detection switch includes a forward detection switch and a reverse detection switch, the forward detection switch detects that the winding length of the wire increases, and the reverse detection switch detects that the winding length of the wire decreases.

    본 발명은 활선상태의 가공배전선 유지보수를 위해 송전탑에서 작업하는 작업자가 감전 등과 같은 위험지역에 진입시에 이를 신속하게 경고하여 안전사고를 방지시킬 수 있는 안전보조장치에 관한 것으로, 더욱 상세하게는 속이 빈 함체의 형상으로 이루어지되 체결수단에 의해 서로 분리 결합가능한 두 분체로 이루어지며, 내부에 제어부가 구비되는 케이스 및 상기 케이스 내부에 회전가능하게 구비되되 외면에는 작업복과 연결되는 와이어가 권취 가능하게 구비되며, 회전시에 서로 다른 감지스위치와 전기적으로 면접하여 상기 제어부를 통해 상기 와이어의 권취길이가 판단되어 작업자에게 위험지역 진입 여부를 알려줄 수 있게 구비되는 롤러부재를 포함하되, 감지스위치는 정방향 감지스위치 및 역방향 감지스위치를 포함하며, 상기 정방향 감지스위치는 상기 와이어의 권취길이가 늘어나는 것을 감지하고, 상기 역방향 감지스위치는 상기 와이어의 권취길이가 줄어드는 것을 감지하는 것을 특징으로 한다.
