The invention discloses a crane for building construction, and relates to the technical field of cranes. The crane comprises a moving seat, electric lifting rods are fixed to the four corners of the top of the moving seat, a mounting frame is fixed to the tops of the electric lifting rods, a moving beam is slidably mounted in the mounting frame, a crane body is fixed to the top of the moving beam, and a lifting rope is arranged at the bottom of the crane body; a telescopic square frame is fixed to the bottom of the movable beam, U-shaped swing rods are hinged to the four corners of the telescopic square frame, and torsional springs are arranged between the U-shaped swing rods and the telescopic square frame. Through cooperation of the U-shaped swing rod and the abutting wheel, the U-shaped swing rod buffers swing force borne by the lifting rope, so that the problems that goods swing, out of control and even toppling or falling off are caused due to large-amplitude swing of the lifting rope are avoided, and then the stability of the lifting rope in the goods lifting process is improved.

    本发明公开了一种建筑施工用起重机,涉及起重机技术领域。本发明包括移动座,所述移动座的顶部四角处固定有电动升降杆,所述电动升降杆的顶部固定有安装框,所述安装框的内部滑动安装有移动梁,所述移动梁的顶部固定有起重机主体,所述起重机主体的底部设置有吊绳,所述移动梁的底部固定有伸缩方架,所述伸缩方架的四角处均铰接有U形摆动杆,且U形摆动杆与伸缩方架之间设有扭簧。本发明通过U形摆动杆和抵触轮配合使U形摆动杆对吊绳受到的晃动力进行缓冲,从而避免了吊绳发生大幅度的晃动,导致货物摇摆、失控,甚至引发倾倒或脱落的问题,进而提高了吊绳吊装货物过程中的稳定性。
