상기한 목적을 달성하기 위하여 본 고안은 기어드모터에 의해 스퍼기어가 서로 맞물려 회전되면 스프로킷에 감기는 연결체인에 의해 센터샤프트가 서로 반대방향으로 구동되고, 센터샤프트와 가이드샤프트의 스프라킷에 감기는 리프팅체인이 회전되면 후크핀이 서로 반대방향으로 이동되어 핀홈에 안착되며, 리밋스위치에서 후크핀이 핀홈에 안착됨을 감지하여 상기 기어드모터를 정지시키도록 설치되는 것을 특징으로 하는 후크의 폭조정장치를 제공한다.In order to achieve the above object, the present invention is driven to the opposite direction by the center shaft and the sprocket of the center shaft and the guide shaft by a connecting chain wound around the sprocket when the spur gears are engaged with each other by the geared motor. When the lifting chain is rotated, the hook pins are moved in opposite directions to be seated in the pin grooves, and the limit switch detects that the hook pins are seated in the pin grooves and is installed to stop the geared motor. To provide.
도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.
도2는 본 고안에 따른 후크의 폭조정장치를 나타내는 사시도이고, 도3은 본 고안에 따른 후크의 폭조정장치의 작동상태를 나타내는 상태도이다.Figure 2 is a perspective view showing a width adjusting device of the hook according to the present invention, Figure 3 is a state diagram showing the operating state of the width adjusting device of the hook according to the present invention.
후크본체(6)의 상부 중앙에 설치되는 기어드모터(11)를 작동시키게 되면 구동스퍼기어(12)가 회전되면서 종동스퍼기어(12-1)를 회전시키게 되고, 이때 구동스퍼기어와 종동스퍼기어는 서로 맞물려 회전되면서 서로 반대방향으로 회전된다.When the geared motor 11 installed at the upper center of the hook body 6 is operated, the driving spur gear 12 is rotated while the driving spur gear 12 is rotated. At this time, the driving spur gear and the driven spur gear Are rotated in opposing directions while being engaged with each other.
여기서, 구동스퍼기어(12)와 종동스퍼기어(12-1)에는 각각 보다 작은 직경의 구동스프라킷(7,7-1)이 고정 부착되어 있다.Here, the drive sprockets 7 and 7-1 having smaller diameters are fixedly attached to the drive spur gear 12 and the driven spur gear 12-1, respectively.
그리고, 후크본체(6)의 상부에 베어링블록(24)에 의해 지지되도록 설치되는 센터샤프트(15,15-1)에는 그 중단부에 각각 동력전달용 스프라킷(13,13-1)이 설치되어 있다.In addition, the center shafts 15 and 15-1 installed on the hook body 6 so as to be supported by the bearing block 24 have power transmission sprockets 13 and 13-1, respectively. It is installed.
이때, 구동스프라킷(7,7-1)과 동력전달용 스프라킷(13,13-1)이 각각 연결체인(17,17-1)에 의해 연결되어 있어 센터샤프트(15,15-1)를 회전시키게 된다.At this time, the drive sprockets 7 and 7-1 and the power transmission sprockets 13 and 13-1 are connected by connecting chains 17 and 17-1, respectively, so that the center shafts 15 and 15- Rotate 1).
또한, 센터샤프트(15,15-1)의 양단에는 각각 종동스프라킷(14,14-1)이 체결되어 있고, 센터샤프트의 외측편에 베어링하우징(24)에 의해 지지되도록 설치되는 가이드샤프트(16)의 양단에도 각각 종동스프라킷(14,14-1)이 고정적으로 끼워져 있다.Further, guide sprockets 14 and 14-1 are fastened to both ends of the center shafts 15 and 15-1, and guide shafts are provided to be supported by bearing housings 24 on the outer side of the center shaft. The driven sprockets 14 and 14-1 are respectively fixedly fitted to both ends of (16).
여기서, 후크핀(19)에는 그 양단에 각각 2개씩의 핀러그(Pin Lug)(20)가 조립되어 있고, 이 핀러그에는 종동스프라킷(14,14-1)에 감기는 리프팅체인(18,18-1)의 양단이 연결되어 있다.Here, two pin lugs 20 are assembled at both ends of the hook pin 19, and a lifting chain wound around the driven sprockets 14 and 14-1 is fitted to the pin lugs. 18,18-1) are connected at both ends.
한편, 핀홈(5)의 하부측에는 각각 리밋스위치(2,22-1)가 설치되고, 이 리밋스위치는 핀홈에 후크핀(19)의 안착을 감지하여 케이블(23,23-1)을 통해 기어드모터(11)를 제어하게 된다.On the other hand, the lower side of the pin groove (5) is provided with limit switches (2, 22-1), respectively, the limit switch detects the mounting of the hook pin 19 in the pin groove and geared through the cable (23, 23-1) The motor 11 is controlled.
이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.
기어드모터(11)를 작동시키게 되면 스퍼기어(12,12-1)가 서로 맞물려 회전하게 되고, 이에 따라 연결체인(17,17-1)에 의해 센터샤프트(15,15-1)가 서로 반대방향으로 구동하게 된다.When the geared motor 11 is operated, the spur gears 12 and 12-1 mesh with each other to rotate, so that the center shafts 15 and 15-1 are opposite to each other by the connecting chains 17 and 17-1. Drive in the direction.
이때, 삼각형상을 이루는 리프팅체인(18,18-1)은 서로 반대방향을 회전되면서 후크핀(19)을 안쪽으로 옮기거나 바깥쪽으로 옮기게 된다.At this time, the lifting chain (18,18-1) forming a triangular shape is to move the hook pin 19 inward or outward while rotating in the opposite direction to each other.
여기서, 후크핀(19)이 핀홈(5)에 안착되면 이를 리밋스위치(22,22-1)에 의해 감지되고, 리밋스위치에서는 감지신호를 케이블(23,23-1)을 통해 기어드모터(11)에 전송하게 된다.Here, when the hook pin 19 is seated in the pin groove 5, it is detected by the limit switches 22 and 22-1, and the limit switch detects the detection signal through the cables 23 and 23-1. ).
그리고, 기어드모터(11)는 리밋스위치(22,22-1)의 감지신호가 모두 수신되면 자동적으로 작동이 멈추게 된다.In addition, the geared motor 11 is automatically stopped when all of the detection signals of the limit switches 22 and 22-1 are received.
본 고안은 크레인의 후크 간격을 들어 올릴 장비(용선래들,고철장입용 슈트 및 바스켓 등)의 폭으로 용이하게 조정함으로써 작업의 생산성을 높이고, 안전사고를 미연에 방지할 수 있는 효과를 제공하게 된다.The present invention can easily adjust the width of the hooks of the crane to the width of the equipment (such as molten iron ladle, steel loading chute and basket) to increase the productivity of the work, to provide an effect that can prevent accidents in advance. do.
