The present invention relates to a winch with a wire loosening prevention unit. The winch according to the present invention comprises: a housing including a pair of support frames arranged to be spaced at a regular distance; a drum installed within the housing to be able to rotate and having an outer circumferential surface around which a wire rope is wound; a driving motor installed in the housing to rotate the drum; and a loosening prevention unit pressing the wire rope wound around the drum to prevent the wire rope from being loosened. The loosening prevention unit includes: a fixation shaft coupled between a pair of support frames and arranged to have a predetermined height from the upper part of the drum; a main shaft installed in parallel with the fixation shaft to be spaced at a regular distance and link-coupled to the fixation shaft while having both tip ends coupled to the support frames by elastic members to be pressed downwards; and a pressing roller coupled to the lower part of the main shaft to come into contact with the outer circumferential surface of the drum for pressing the wire rope wound around the drum. Therefore, the present invention enables the wire rope to be wound around the drum in close contact with the same and prevents the wire rope having been already wound around the drum, from being loosened, thereby stably lifting a structure.

    본 발명은 와이어 풀림방지부가 구비된 윈치에 관한 것으로, 본 발명의 윈치는 일정거리 이격되게 배치되는 한 쌍의 지지프레임을 포함하는 하우징, 상기 하우징의 내부에서 회전할 수 있도록 설치되며, 외주면에 와이어로프가 권취되는 드럼, 상기 하우징에 설치되어, 상기 드럼을 회전시키는 구동모터, 상기 드럼에 권취되는 와이어로프를 가압하여, 상기 와이어로프가 풀리지 않도록 하는 풀림방지부로 구성되되, 상기 풀림방지부는 한 쌍의 지지프레임 사이에 결합되며, 상기 드럼의 상부로부터 일정높이를 가지도록 마련되는 고정축, 상기 고정축과 평행으로 일정간격 이격되게 설치되며, 상기 고정축에 링크 결합되되, 양 끝단부가 탄성부재에 의해 지지프레임에 결합되어, 하방향으로 가압되는 메인축, 상기 메인축의 하부에 결합되어, 상기 드럼의 외주면에 접촉됨으로써 상기 드럼에 권취되는 와이어로프를 가압하는 가압롤러를 포함하는 것을 특징으로 하며, 따라서 와이어로프가 드럼에 밀착되게 권취되며, 이미 드럼에 권취된 와이어로프가 풀리지 않도록 하여, 안정적으로 구조물을 인양할 수 있는 현저한 효과가 있다.
