Abstract
본 발명은 건축 및 토목공사 현장에서 철골등 각종 자재를 올리고 내리는데 이용되는 타워크레인(tower crane) 등 각종 크레인의 로프에 연결되는 후크블록(hook block)에 관한 것으로, 특히 후크(hook)의 회전을 원격조정하여 철골등 각종 자재를 설치하고자 하는 것에 용이하게 정위치시킬 수 있도록 된 크레인용 후크블록에 관한 것이다.The present invention relates to a hook block connected to a rope of various cranes, such as tower cranes used to raise and lower various materials, such as steel frame, in construction and civil engineering works. It relates to a hook block for a crane that can be easily adjusted to the remote control to install various materials such as steel frame.
본 발명의 크레인용 후크블록은 활차바퀴(4)의 하부 위치에서 취크(1)의 고정된 정, 역회전가능한 모터(10)와, 상기 모터축의 회전을 감속시켜 후크(3)의 축(3a)에 전달하기 위해서 모터축과 후크(3)의 축(3a) 사이에 설치된 감속기(11)와, 상기 모터(10)를 제어하기 위한 수신부가 포함되어 있고 모터(10)의 정, 역회전 및 정지를 제어하도록 되어 있는 모터제어장치(12)가 구동되어 있으며, 상기 모터제어장치(12)를 무선으로 원격 조정하는 원격무선조정기(13)가 일조로 구비되어 있는 것을 특징으로 한다.The hook block for crane of the present invention is a fixed forward and reverse rotational motor 10 of the chuck 1 in the lower position of the pulley wheel 4 and the shaft 3a of the hook 3 by reducing the rotation of the motor shaft. Is provided between the motor shaft and the shaft (3a) of the hook (3), and a receiver for controlling the motor (10) and forward, reverse rotation and The motor control device 12 is configured to control the stop, and the remote control device 13 for remotely controlling the motor control device 12 is provided as a group.
