A rotatable low-clearance bridge type carrying crane comprises a crane carriage running on a main beam, and is characterized in that a horizontally rotating turntable is arranged on the crane carriage, a rotating part of the turntable is connected with a multi-section telescopic arm, and the multi-section telescopic arm stretches out and draws back in the vertical direction under the traction of a winch; and the lower end of the multi-section telescopic arm is connected with a grabbing mechanical arm. Four degrees of freedom are provided for the grabbing mechanical arm, the grabbing mechanical arm can grab goods in a motion space through the four degrees of freedom, the goods are placed at another place after the grabbing mechanical arm rotates by a certain angle, and the orientation problem of goods taking and placing is solved. Due to the fact that the multi-section telescopic arm has good rigidity and a very low swing amount, accurate positioning of goods taking and placing can be achieved. Manual assistance is not needed, the labor cost is reduced, and unmanned and intelligent operation of the bridge type carrying crane is facilitated.

    一种可旋转低净空桥式搬运起重机,包括运行在主梁上的起重小车,其特征是:在起重小车上设有水平旋转的转盘,在转盘的转动部连接有多节伸缩臂,多节伸缩臂在卷扬机的牵引下,沿竖直方向伸缩;在多节伸缩臂的下端连接有抓料机械手。本发明为抓料机械手提供了四个自由度,该四个自由度使抓料机械手能够在运动空间内抓取货物,转动一定角度后,再将货物放置在另一地点,解决了货物取放的朝向问题。由于多节伸缩臂具有良好的刚性和很低的摇摆量,能够实现货物取放的精确定位。本发明不需要人工辅助,不但降低了人工成本,而且有利于桥式搬运起重机的无人化、智能化。
