The invention discloses a tower crane introducing a tower crane safety channel on an outer sleeve frame, and belongs to the field of auxiliary equipment of tower cranes. The tower crane comprises a tower crane body, two main chord members are arranged at the lower end of the outer sleeve frame of the tower crane body, the two main chord members are arranged on the same side face, connecting supporting legs are arranged on the side edges of the bottom ends of the two main chord members, a suspension bridge bottom plate is arranged on the connecting supporting legs, one end of the suspension bridge bottom plate is hinged to the connecting supporting legs, a steel wire rope is arranged on the suspension bridge bottom plate, and the other end of the steel wire rope is connected with the main chord members. According to the tower crane, the installation is simpler and more convenient, folding and unfolding are free, the workload of installation personnel is reduced, the channel can be lifted along with the jacking and section increasing of the tower crane, carrying is reduced, the high-altitude operation amount is reduced, an operator can safely and conveniently walk to the tower crane from a building, a suspension bridge can be lifted along with the section increasing of the tower crane, and the suspension bridge can be folded and unfolded; and the requirement that the operator walks into the tower crane from the building can be met through the suspension bridge, the automatic ascending channel does not need to be disassembled and assembled, labor is saved, and safety and reliability are achieved.

    本发明公开了一种在外套架上引入塔机安全通道的塔机,属于塔式起重机的辅助设备领域,包括塔机,塔机的外套架下端设置有两根主弦杆,两根主弦杆设置在同一侧面上,两根主弦杆的底端侧边设置有连接支脚,连接支脚上设置有吊桥底板,吊桥底板一端与连接支脚铰接,吊桥底板上设置有钢丝绳,钢丝绳的另一端与主弦杆连接。本发明安装更加简便,收放自如,减少安装人员的工作量,通道可以随塔机的顶升加节升高而升高,减少搬运,减少高空作业量,操作人员从建筑物上走到塔机上安全方便,吊桥可随塔机的加节升高而升高,吊桥可以收放,通过吊桥可以满足操作人员从建筑物走进塔机内的需求,自动上升通道无需拆装。节省人工,安全可靠。
