The invention relates to the technical field of tower cranes, in particular to a construction tower crane. The construction tower crane comprises a rotary base on which a tower crane tower body is fixedly mounted through a bolt. The construction tower crane is characterized in that a rotary butt joint seat is mounted on the rotary base in a welded manner, a rotary seat is mounted on the rotary butt joint seat through a bearing, and a second gear ring is arranged on the rotary seat. The construction tower crane has the beneficial effects that by means of the designed construction tower crane structure, light signals, sound wave signals and wireless signals can be effectively used for transmitting danger signals and fault signals, the danger signals and the fault signals can be directionallytransmitted through a first spotlight and a first loudspeaker, meanwhile, an operator in a tower crane control room can conveniently judge whether people in corresponding ground regions correctly receive corresponding information or not through a first camera and a second camera, and therefore it is guaranteed that the danger signals can be correctly transmitted within a first time.

    本发明涉及塔吊技术领域,具体为一种建筑塔吊,包括通过螺栓与塔吊塔身固定安装的回转底座,其特征在于:回转底座上焊接安装有回转对接座,回转对接座上通过轴承安装有回转座,且回转座上设置有第二齿圈。有益效果为:本发明设计的建筑塔吊结构能够有效的利用灯光信号、声波信号和无线信号来传达危险信号和故障信号,而且还能够通过第一射灯和第一扬声器来实现对危险信号和故障信号的定向传达,同时位于塔吊控制室的操作人员也能够方便的通过第一摄像头和第二摄像头来判断地面相应区域的人员是否正确的接收到了相应的信息,从而确保了危险信号在第一时间内能够被正确的传达。
