The invention discloses a pipeline lifting device of a crane and a control method of the pipeline lifting device. The upper device and the lower device which are separated from each other are arranged, the lower device is connected and lifted by the steel wire rope through the lifting hook system to control the lower device to ascend and descend, and the upper device comprises a fixing frame, a first limiting device, a rotary driving mechanism, a rotary connecting shaft and a second limiting device. The lower device comprises a rotating column, a limiting rod, a supporting frame, a limiting block and a balance beam, when the limiting rod is connected with the first limiting device in a clamped mode, the rotating column and the fixing frame are mutually fixed, the limiting block is connected with the second limiting device in a clamped mode, and the supporting frame and the balance beam are mutually fixed. The rotary driving mechanism drives the rotary connecting shaft to rotate to drive the balance beam to rotate, so that a steel wire rope can be prevented from being wound when the supporting frame is controlled to rotate, steering control over a pipeline fixed to the supporting frame can be achieved by controlling the supporting frame to rotate, the working intensity is reduced, and the working efficiency is improved. And the operation safety is ensured.
本申请公开了一种起重机的管道起吊装置及其控制方法。本申请通过设置相互分离的上部装置和下部装置,下部装置被钢丝绳通过吊钩系统连接吊起实现控制下部装置升降,所述上部装置包括固定架、限位装置一、旋转驱动机构、旋转连接轴和限位装置二,所述下部装置包括旋转柱、限位棒、支撑架、限位块和平衡梁,当所述限位棒与所述限位装置一相卡接时,所述旋转柱与所述固定架相互固定,所述限位块与所述限位装置二相卡接,所述旋转驱动机构驱动所述旋转连接轴转动带动所述平衡梁旋转,这样可实现在控制支撑架旋转时也能防止钢丝绳缠绕,控制支撑架旋转即可实现对固定在支撑架上的管道进行转向控制,减小了作业强度,提升了工作效率,保障了作业安全。
