The invention belongs to the technical field of cranes, and discloses a tower crane with an amplitude debugging mechanism. The tower crane with the amplitude debugging mechanism comprises a tower body, a rotary platform is arranged at the top end of the tower body, a cargo boom assembly is installed on the rotary platform, a balancing weight is arranged on one side of the cargo boom assembly, and a variable amplitude trolley is arranged on the lower side of the other side of the cargo boom assembly. According to the tower crane with the amplitude debugging mechanism, the design of the amplitude debugging mechanism is utilized, the double-winding-drum design is adopted, winding and unwinding operation of the two ends of a steel cable is processed correspondingly, unified control is conducted through the amplitude changing motor, synchronous rotation of the two ends is ensured, and the cleaning guide mechanism is matched; in the rotating process of the winding drum, the winding drum can be guided by the spiral rib to move on the sliding rail, it is ensured that the steel cable can directly enter and exit through the guide hole, meanwhile, the steel cable can be orderly wound through cooperation with the spiral guide rib, the situation that the steel cable is separated from the winding drum or stacked is avoided, and the problems proposed in the background technology are solved.

    本发明属于起重机技术领域,公开了一种带有幅度调试机构的塔式起重机。该带有幅度调试机构的塔式起重机,包括塔身,所述塔身顶端设有回转平台,所述回转平台上安装有起重臂总成,所述起重臂总成一侧设有配重块,起重臂总成另一侧的下侧设有变幅小车。该带有幅度调试机构的塔式起重机,利用幅度调试机构的设计,采用双卷筒设计,分别处理钢索两端的收放操作,由变幅电机进行统一控制,确保了两者的同步转动,且配合清洁导向机构的设计,在卷筒转动的过程中能够受螺旋筋导向在滑轨上移动,确保钢索能够通过导向孔直进直出,同时配合螺旋导向筋能够确保钢索有序缠绕,避免出现钢索脱离卷筒或相互堆叠的情况,解决了背景技术中提出问题。
