Pile casing lifting device and piling machine
The invention relates to the technical field of engineering machinery, and provides a pile casing lifting device and a piling machine.The pile casing lifting device comprises a mast, a movable clamp holder and a hoisting mechanism, a first end of the mast is provided with a first pulley, the movable clamp holder comprises a movable clamp holder body and a second pulley, the movable clamp holder body is slidably connected with the mast, and the second pulley is connected with the movable clamp holder body; the sliding direction is parallel to the extending direction of the mast, the second pulley is rotationally connected with the movable clamp holder body, and the rotating axis of the first pulley and the rotating axis of the second pulley are both perpendicular to the extending direction of the mast; the hoisting mechanism comprises a winding drum and a traction rope with the first end connected with the winding drum, the second end of the traction rope sequentially bypasses the first pulley and the second pulley and then is fixedly connected with the mast, and the distance between the second end of the traction rope and the first end of the mast is smaller than that between the second pulley and the first end of the mast. By means of the arrangement, the problems that in the prior art, when a long pile casing is lifted and lowered, operation is tedious, and working efficiency is low are solved.
本发明涉及工程机械技术领域，提供一种护筒升降装置及桩工机械，其中，护筒升降装置包括桅杆、动夹持器和卷扬机构，桅杆的第一端设有第一滑轮，动夹持器包括动夹持器本体和第二滑轮，动夹持器本体与桅杆滑动连接，滑动方向与桅杆的延伸方向平行，第二滑轮与动夹持器本体转动连接，第一滑轮的转动轴线和第二滑轮的转动轴线均与桅杆的延伸方向垂直；卷扬机构包括卷筒和第一端与卷筒相连接的牵引绳，牵引绳的第二端依次绕过第一滑轮和第二滑轮后与桅杆固定连接，牵引绳的第二端与桅杆的第一端之间的距离小于第二滑轮与桅杆的第一端之间的距离。如此设置，解决了现有技术中在对长度较大的护筒进行提升与下放时存在操作繁琐、工作效率低的问题。
