The invention discloses a double tower body of a tower crane, which comprises a plurality of attachment sections, an outer tower body, a plurality of adjusting sections, an outer tower body foot margin, an inner tower body foot margin and an inner tower body, and relates to the technical field of tower cranes, the attachment sections are connected into a whole to form a double tower body structure, and the stress transmission paths of the tower bodies are separated; in other words, the outer tower body mainly transmits the tipping moment of the tower crane, and the inner tower body mainly transmits the vertical force of the tower crane, so that the stress of the original single tower body is reduced, the loading capacity of the whole tower body is improved, the strength and rigidity of the whole tower body are greatly improved, and the maximum free height of the tower crane is increased to meet the actual working requirements. The tower body is simple in structure and ingenious in conception, the maximum free height of the tower body is increased, the typhoon resistance and the equipment utilization rate of the tower crane are improved, the blank of the tower body of the type is filled, and the tower body is worthy of wide application and popularization.

    本发明公开了一种塔式起重机双塔身,包括:若干个附着节、外塔身、若干个调整节、外塔身地脚、内塔身地脚以及内塔身,本发明涉及塔式起重机技术领域,通过附着节连接成一体形成双塔身结构,将塔身的受力传递路线分开,即外塔身主要传递塔机倾翻力矩,内塔身主要传递塔机竖向力,进而减轻原单塔身的受力,增加整体塔身受载能力,大大提高了整个塔身的强度和刚度,从而提高塔式起重机的最大自由高度,以满足实际工作要求。本发明结构简单、构思巧妙,不但提高了塔身最大自由高度,而且还提高了塔机的抗台风能力及设备利用率,填补了此类塔身的空白,值得广泛的推广应用。
