The invention provides a gravity balance structure of a crane, and belongs to the technical field of crane machines. The gravity balance structure comprises a suspension arm ring, a connecting plate is movably connected below the suspension arm ring, a mounting seat is fixedly connected below the connecting plate, an assembly plate arranged in the middle of the connecting plate, the connecting plate is arranged at an opening of the assembly plate, a fixing shaft is connected between the connecting plate and the assembly plate in a penetrating mode, a limiting section extends from the inner endof the opening of the assembly plate, a plurality of mounting holes are formed in the surface of the assembly plate, a spring is fixedly connected below the connecting plate, a movable block is fixedly connected to the lower end of the spring, and the spring and the movable block are arranged in the mounting base, a piston is arranged at the bottom inside the mounting base, and a balancing weightis fixedly connected below the mounting base. The gravity balance structure of the crane is stable in structure, the crane can be kept perpendicular to the horizontal line all the time by arranging the assembly plate, the spring and the balancing weight, it is guaranteed that an aerial work platform cannot be inclined due to the gravity effect of a crane jib, and installation is convenient.

    本发明提供了一种起重机重力平衡结构,属于起重机机械技术领域,包括吊臂环,吊臂环的下方活动连接有连接板,连接板的下方固定连接有安装座,连接板的中部设置有装配板,连接板设置在在装配板的开口处,连接板和装配板之间贯通连接有固定轴,装配板的开口处内端延伸有限位段,装配板的表面开设有多个安装孔,连接板的下方固定连接有弹簧,弹簧的下端固定连接有活动块,弹簧和活动块设置在安装座内,安装座的内部底部设置有活塞,安装座的下方固定连接有配重块。该种起重机重力平衡结构,结构稳定,通过设置装配板、弹簧和配重块,可以使起重机始终保持与水平线相垂直的状态,确保高空作业平台不会受起重吊臂重力影响而发生倾斜,且便于安装。
