Description
제1도는 본 고안의 장치 위치도.1 is a device position diagram of the present invention.
제2도는 본 고안의 구조 사시도.2 is a perspective view of the structure of the present invention.
제3도는 제2도의 구조 단면도.3 is a structural cross-sectional view of FIG.
본 고안은 지브크레인의 붐(BOOM)와이어가 작동중 또는 교환시에 풀리거나 꼬여서 와이어가 쉽게 손상되거나 또 이로 인하여 와이어가 절손되면 대형사고가 유발되는 것을 방지하게 한 와이어 꼬임 방지장치에 관한 것이다.The present invention relates to a wire twist preventing device that prevents a large accident from occurring when the wire of the jib crane is loosened or twisted during operation or exchange, or when the wire is broken.
종래 붐 와이어의 끝단은 붐 한쪽 브래킷에 묶어 고정하였던 것인데 크레인 작동중에 와이어가 도르레 사시에서 감기고 풀릴 때 회전력이 발생하여 끝단에 고정된 부분에는 강한 꼬임과 풀림이 반복적으로 발생되어 와이어가 손상됨으로서 자주 교체해야 되며 이 손상이 극심할 경우 와이어가 절손되면 대형사고가 유발되는 것이다.Conventionally, the end of the boom wire was fixed to one side of the boom bracket and fixed. When the wire is wound and unrolled from the pulley during the operation of the crane, rotational force is generated. If this damage is severe, a broken wire can cause a major accident.
또한 와이어 교체 작업시에는 와이어 회전으로 인한 안전사고의 위험도 높은 것이다.In addition, there is a high risk of safety accidents due to wire rotation during wire replacement.
본 고안은 대형크레인에 관한 종래의 결점을 제거코져 와이어 끝부분을 회전되게 함으로서 회전력을 방출시키게 한 것이다.The present invention eliminates the conventional drawbacks of large cranes, allowing the tip of the wire to rotate to release the rotational force.
이하 고안의 요지를 첨부 도면에 의하여 설명하면 다음과 같다.Hereinafter, the subject matter of the present invention will be described with reference to the accompanying drawings.
크레인붐(1)을 승강시키는 와이어(2)의 끝단을 회전봉(2)에 고정하고 회전봉(3)은 축판(4)내에 베어링(5)로서 축설시킨 구조이다.The end of the wire 2 which raises and lowers the crane boom 1 is fixed to the rotating rod 2, and the rotating rod 3 is built up as a bearing 5 in the shaft plate 4. As shown in FIG.
이와 같이 본 고안은 봄(1)의 승강시 와이어(2)의 인장력과 함께 발생하는 강한 회전력이 와이어 끝단에 도달하더라도 회전봉(3)이 축판(4)에서 베아링(5)과 함께 회전되어 방출되는 것이어서 와이어(2) 자체가 꼬이는 폐단이 방지되는 것이다.In this way, the present invention, even if a strong rotational force generated with the tension of the wire (2) during the lifting of the spring (1) reaches the end of the wire is released by rotating the rotating rod (3) with the bearing (5) in the shaft plate (4) This prevents the closed end from which the wire 2 itself is twisted.
그러므로 본 고안은 대형사고를 유발하는 중장비의 안전장치 부여와 소모품 절감의 2중 효과가 있는 것이다.Therefore, the present invention has a double effect of providing safety devices and reducing consumables of heavy equipment causing large accidents.
