A basic arm, a second-section arm, a third-section arm, a fourth-section arm, a fifth-section arm and a sixth-section arm are sequentially and mutually nested and connected, the second-section arm and the third-section arm are driven by two oil cylinders, and the fourth-section arm, the fifth-section arm and the sixth-section arm are respectively driven by corresponding inhaul cables and guide fixed pulleys to synchronously stretch out and draw back. The five knuckle arms stretch out and draw back synchronously, the stretching-out and drawing-back speed is high, and operation working conditions of various arm lengths are met.
本发明公开了一种双缸绳排同步六节伸缩起重臂,基本臂、二节臂、三节臂、四节臂、五节臂和六节臂顺次相互嵌套连接,二节臂和三节臂通过两个油缸驱动,四节臂、五节臂和六节臂分别采用对应的拉索和导向定滑轮带动进行同步伸缩,五个节臂同步伸缩、伸缩速率快,且满足各种臂长的作业工况。
