The invention relates to the technical field of tower cranes for building construction, in particular to tower crane equipment for building construction, which comprises a tower body, movable arms are fixedly connected to the top end of the tower body, and a fixing mechanism for connecting the two movable arms is fixedly connected to one end of each movable arm. The bottom face of the movable arm is in sliding connection with a movable hoisting mechanism which is used for hoisting materials and can move the materials. According to the invention, one end of the variable-amplitude vehicle is rotatably provided with the threaded sleeve in screwed connection with the threaded pipe in a penetrating manner, and the toothed column is engaged with the rack at the corresponding position, so that the threaded pipe can be in screwed connection with the threaded sleeve at the corresponding position, and the threaded pipe is retracted into the threaded sleeve at the corresponding position or is separated from the threaded sleeve at the corresponding position; therefore, a circuit in the variable-amplitude vehicle is controlled to be powered on or powered off, and an operator can control the variable-amplitude vehicle to move conveniently.

    本发明涉及建筑施工塔吊技术领域,具体涉及一种建筑施工用的塔吊设备法,包括塔身,所述塔身顶端固定连接有动臂,所述动臂的一端固定连接有用于将两个动臂连接的固定机构,所述动臂的底面滑动连接有用于吊装材料且能将材料移动的移动吊装机构。本发明中,通过将变幅车的一端贯穿转动有与螺纹管旋合连接的螺纹套,通过齿柱与对应位置处的齿条啮合,可以使螺纹管与对应位置处的螺纹套旋合连接,从而收进对应位置处的螺纹套内部或从对应位置处的螺纹套脱离,从而控制变幅车内的电路通电或断电,方便操作人员控制变幅车的移动。
