The invention relates to the technical field of cranes, in particular to a movable tubular pile crane. The crane comprises a main arm; a groove is formed in the main arm; a rotating shaft is fixedly installed in the groove; a damping plate is fixedly installed in the groove; a corner piece is rotationally installed on the rotating shaft; a disc and a suspension arm are fixedly installed on the corner piece; a side plate is fixedly installed on the main arm; a pushing and pressing piece is movably installed on the side plate; a balance spring is fixedly connected to the pushing and pressing piece; a center plate is fixedly installed on the side plate; and a lever is rotationally installed on the center plate. According to the crane, the corner piece is a connecting assembly of the suspension arm and the main arm, a sliding block is driven by a sliding block-crank structure to move up and down in a reciprocating mode, the pressure between the disc and the damping plate can be increased,the frictional resistance borne by the corner piece is increased, thus vertical shaking of a clamp suspension beam is reduced, the suspension arm can be directly locked, the clamp suspension beam is lifted in time when breaking down, and the safety of the crane is guaranteed.

    本发明涉及起重机技术领域,具体为一种移动式管桩起重机,包括主手臂,所述主手臂上设置有凹槽,且凹槽中固定安装有转轴,且凹槽中固定安装有阻尼板,所述转轴上转动安装有角件,且角件上固定安装有碟片和吊臂,所述主手臂上固定安装有侧板,且侧板上活动安装有推压件,所述推压件上固定连接有平衡弹簧,所述侧板上固定安装有中心板,且中心板上转动安装有杠杆;本发明中角件是吊臂与主手臂的连接组件,通过曲柄滑块结构带动滑块进行往复的上下移动,可以使得碟片与阻尼板之间的压力增加,增加了角件受到的摩擦阻力,从而减少夹具吊梁竖直向的晃动,也可以将吊臂直接锁死,夹具吊梁故障时及时将其吊住,保证起重机的安全性。
