이에 따라, 상기 와이어로프(150)의 정상적인 감김시 상기 감지센서(30)는 스프링부재(25)에 의해서 상방으로 탄력지지하는 상기 롤러지지대(24)의 하부면과 이격되어 경고신호를 발생하지 않는 반면에, 상기 와이어로프(150)의 비정상적인 감김시 상기 감지센서(30)는 스프링부재(25)를 압축시키면서 하방으로 이동되는 롤러지지대(24)의 하부면과 접하여 경고신호를 발생시키며, 감지딘 신호는 제어판넬(35)로 전송되어 작업자에게 와이어로프(150)의 탈선상태를 인식하도록 경고등(36)으로 점등시키거나, 크레인운전을 일시중지시키도록 크레인전원(37)을 차단시킨다.Accordingly, when the wire rope 150 is normally wound, the detection sensor 30 is spaced apart from the lower surface of the roller support 24 which is elastically supported upward by the spring member 25 so as not to generate a warning signal. On the other hand, when the wire rope 150 is abnormally wound, the detection sensor 30 generates a warning signal in contact with the lower surface of the roller support 24 moved downward while compressing the spring member 25, The signal is transmitted to the control panel 35 to illuminate the worker with a warning light 36 to recognize the derailment state of the wire rope 150, or cut off the crane power source 37 to pause the crane operation.

상술한 바와같은 구성을 갖는 본 고안에 따른 권취드럼의 와이어로프 절단방지장치의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the wire rope cutting prevention device of the winding drum according to the present invention having the configuration as described above are as follows.

본 고안에 따른 권취드럼의 와이어로프 절단방지장치(1)는 권상, 권하작업에 따라 드럼모터(160)의 정,역방향 회전에 의해서 우회전 또는 좌회전되는 권취드럼(140)과 나란하게 설치된 나사축(10)에 조립된 이동블록(20)의 감지롤(29)이 정상적으로 나사골(2)에 권취되는 와이어로프(150)보다 항상 1피치 앞에 위치하면서 비정상적으로 나사골(2)에 권취되는 와이어로프(150)의 탈선여부를 감지하는 것이다.Wire rope cutting prevention device (1) of the winding drum according to the present invention is a screw shaft installed in parallel with the winding drum 140 is rotated to the right or left by the forward, reverse rotation of the drum motor 160 in accordance with the hoisting, hoisting operation ( The sensing roll 29 of the movable block 20 assembled in 10 is always one pitch ahead of the wire rope 150 normally wound on the screw bone 2, and the wire rope 150 is abnormally wound on the screw bone 2. ) Is to detect the derailment.

도 3과 4에 도시한 바와같이, 크레인설비(100)의 권상작업이 이루어져 권취드럼(140)이 드럼모터(160)에 의해서 우회전하면, 이에 감겨있는 와이어로프(150)는 나사골(2)을 따라 양쪽에서 중앙으로 감겨오고, 권하작업이 이루어지도록 상기 권취드럼(140)이 드럼모터(160)에 의해서 좌회전되면, 이에 감겨있는 와이어로프(150)는 나사골(2)을 따라 중앙에서 좌우양측으로 풀러나가기 때문에, 상기 와이어로프(150)에 연결된 크레인통(130)을 상부로 올리거나, 하부로 내릴 수 있는 것이다.As shown in Figure 3 and 4, when the hoisting operation of the crane installation 100 is made and the winding drum 140 is turned right by the drum motor 160, the wire rope 150 wound thereon is screw thread (2) When wound along both sides to the center, and the winding drum 140 is turned left by the drum motor 160 so that the unwinding operation is performed, the wire rope 150 wound thereon is from the center to the left and right sides along the screw bones 2. Since it is pulled out, the crane barrel 130 connected to the wire rope 150 can be raised to the top or lowered.

이러한 경우, 상기 권취드럼(140)의 좌우양단과 동력전단수단(12)을 매개로 하여 조립된 나사축(10)이 동일한 회전수로 회전되고, 이에 나사공이 나사결합되고, 케이싱(14)의 안내홈(14a)에 위치된 좌우한쌍의 이동블록(20)은 권상작동시 와이어로프(150)의 감김 이동방향과 동일하게 중앙측으로 이동되고, 권하작동시 풀림이동방향과 동일하게 좌우양측으로 이동되는 한편, 상기 이동블록(20)의 수용공간(21)내에 상하이동가능하도록 조립된 롤러지지대(24)의 감지롤(29)은 상기 와이어로프(150)가 권취되는 나사골(2)보다 항상 1피치 앞에 위치된다.In this case, the left and right ends of the winding drum 140 and the screw shaft 10 assembled through the power shear means 12 is rotated at the same rotational speed, screw holes are screwed to this, the casing 14 of the The left and right pair of moving blocks 20 located in the guide groove 14a are moved to the center side in the same direction as the winding movement direction of the wire rope 150 during the hoisting operation, and moved to the left and right sides in the same way as the unwinding movement direction during the hoisting operation. On the other hand, the sensing roll 29 of the roller support 24 assembled to be movable in the receiving space 21 of the movable block 20 is always 1 than the screw bone 2 in which the wire rope 150 is wound. It is located before the pitch.

여기서, 도 4에 도시한 바와같이, 상기 와이어로프(150)가 권취드럼(140)의 나사골(2)에 정상적으로 권취되는 경우, 상기 롤러지지대(24)에 조립된 감지롤(29)과 대응하는 권취드럼(140)의 나사골(2)에는 와이어로프(150)가 권취되어 있지 않기 때문에, 상기 롤러지지대(24)는 스프링부재(25)에 의해서 상방으로 탄력지지되어 감지센서(30)와 이격된 상태를 유지하여 정상적인 운전상태가 이루어진다.Here, as shown in FIG. 4, when the wire rope 150 is normally wound on the screw bone 2 of the winding drum 140, the wire rope 150 corresponds to the sensing roll 29 assembled to the roller support 24. Since the wire rope 150 is not wound around the screw valley 2 of the winding drum 140, the roller support 24 is elastically supported upward by the spring member 25 to be spaced apart from the sensing sensor 30. It maintains state and normal operation state is achieved.

반면에, 도 5에 도시한 바와같이, 상기 와이어로프(150)가 여러 가지 이유로 후리가 발생하여 권취드럼(140)의 나사골(2)에 비정상적으로 권취되는 경우, 상기 롤러지지대(24)에 조립된 감지롤(29)과 대응하는 권취드럼(140)의 나사골(2)에 와이어로프(150)가 권취되어 있기 때문에, 상기 감지롤(29)과 와이어로프(150)가 접촉되어 하부로 이동되는 롤러지지대(24)에 의해서 스프링부재(25)는 압축되고, 상기 롤러지지대(24)의 하부면과 감지센서(30)가 서로 접해지면서 감지신호를 발생시킨다.On the other hand, as shown in FIG. 5, when the wire rope 150 is rolled up for various reasons and is abnormally wound on the screw bone 2 of the winding drum 140, the wire rope 150 is assembled to the roller support 24. Since the wire rope 150 is wound around the threaded bones 2 of the winding drum 140 corresponding to the sensing roll 29, the sensing roll 29 and the wire rope 150 are contacted and moved downward. The spring member 25 is compressed by the roller support 24, and the lower surface of the roller support 24 and the detection sensor 30 come into contact with each other to generate a detection signal.

이에 따라, 상기 감지센서(30)가 감지되면 그 감지신호는 운전실의 제어판넬(35)로 전송되고, 경고등(36)에 전원이 투입되어 작업자에게 권취드럼(140)의 와이어로프(150) 탈선상태를 알리는 한편, 크레인설비(100)의 공급전원을 차단하여 작업을 중지한다.Accordingly, when the detection sensor 30 is detected, the detection signal is transmitted to the control panel 35 of the cab, and power is supplied to the warning light 36 to derail the wire rope 150 of the winding drum 140 to the worker. While notifying the status, the work is stopped by cutting off the power supply of the crane facility 100.

상술한 바와같은 본 고안에 의하면, 권취드럼(140)의 나사골(2)에 권취되는 와이어로프(150)의 비정상적인 권취상태를 자동으로 감지함으로서, 와이어로프(150)의 탈선시 발생되는 절단사고에 의한 대형설비사고를 미연에 방지할수 있으며, 종래와 같은 수작업에 의존하는 점검작업에 따른 크레인설비의 휴지시간을 절감하여 설비가동율을 향상시킬수 있는 실용상의 효과가 얻어진다.According to the present invention as described above, by automatically detecting the abnormal winding state of the wire rope 150 wound on the screw bone (2) of the winding drum 140, the cutting accident generated when the wire rope 150 is derailed It is possible to prevent the accident of large equipment in advance, and the practical effect of improving downtime of the equipment can be obtained by reducing the downtime of the crane equipment according to the inspection work which is dependent on the manual work as before.
