The invention discloses a large-span rigid suspension multi-fulcrum crane which comprises a truss main beam, a profile rail trolley arranged on the truss main beam, a plurality of spandrel girders arranged above the truss main beam, a profile rail connected to the spandrel girders through hanging pieces, a plurality of reinforcing beams connected to the profile rail trolley in a sliding mode, and a plurality of connecting rods connected to the reinforcing beams. The plurality of stiffening beams are arranged on the truss main beam and located between every two adjacent bearing beams respectively, the main beam trolley is connected to the truss main beam in a sliding mode, the control system is electrically connected with the rail trolley and the main beam trolley, and the control system controls the movement of the main beam trolley and the rail trolley in a centralized mode. According to the crane, the structural advantages of a truss structure are utilized, the mechanical property is not changed, meanwhile, the cost can be saved, the width of the main beam of the crane is increased, the operation space of a hoisting mechanism in the width range is increased, and the use safety is improved.

    本发明公开了一种大跨度刚性悬挂多支点起重机,包括:桁架主梁,桁架主梁上设置有型轨小车,多个承重梁,多个承重梁设置在桁架主梁的上方,多个承重梁上通过吊件连接有型轨,型轨小车滑动连接在型轨上,多个加强梁,多个加强梁设置在桁架主梁上,分别位于相邻的两个承重梁之间,主梁小车,主梁小车滑动连接在桁架主梁上,控制系统,控制系统与型轨小车和主梁小车电连接,控制系统集中控制主梁小车和型轨小车的运动,该起重机利用桁架结构的结构优势,不改变力学性能的同时,还能节约成本,通过型轨小车,提高了起重机主梁的宽度,增加了起升机构在宽度范围内的运行空间,并增加使用安全性。
