The invention discloses a movable arm tower crane with an alarm mechanism, which is characterized in that an alarm device is added on the basis of the traditional movable arm tower crane, the inclination angle of a movable arm is automatically measured when an operator shuts down, and the inclination angle is compared with the allowable inclination angle range of the movable arm; if the inclination angle is not within the range, an audible and visual alarm is sent to an operator, the operator is prompted to start up to adjust the movable arm to be within the safe inclination angle range, and the potential safety hazard of shutdown is fundamentally solved; the alarm device is implemented on the premise that the mechanical structure of the movable arm tower crane is not changed, the alarm device only needs to be coaxially installed at the end of a movable arm rotating shaft, an input shaft of an existing angle sensor only bears rotation acting force to output accurate data, and therefore the input shaft and the rotating shaft need to be coaxially installed. The rotating shaft and the input shaft can be quickly aligned and connected, and the service life of the angle sensor is remarkably prolonged while the monitoring data precision of the angle sensor is ensured.

    本申请公开了一种具有警报机构的动臂塔式起重机,在传统动臂塔式起重机基础上增加警报装置,操作员停机时自动测量动臂倾斜角度,将倾斜角度与动臂所允许的倾斜角度范围作比较,如果倾斜角度没有落在上述范围内则向操作员发出声光警报,促使操作员开机将动臂调整到安全倾斜角度范围内,从根本上解决停机安全隐患;警报装置在不改变动臂塔式起重机本身机械结构的前提下实施,仅需在动臂转轴端部同轴安装即可,现有角度传感器输入轴仅承担旋转作用力才能输出准确数据,这就需要输入轴和转轴同轴安装,本申请提供的连接件,可实现转轴和输入轴的快速对正连接,确保角度传感器的监测数据精度的同时显著延长角度传感器的使用寿命。
