The invention provides a method for calculating the lifting height of a lifting hook of a movable arm type tower crane, and belongs to the technical field of safety monitoring and collision prevention of tower cranes. Calculating the height distance between the hinge point of the cargo boom frame and the ground, the height change distance of the lifting hook caused by amplitude variation of the cargo boom frame and the distance between the lifting hook and the bottom of the cargo boom frame, and then calculating the lifting height of the lifting hook of the movable arm type tower crane. Different static parameters for calculation are built in according to different movable arm tower types when the tower crane leaves a factory, the real-time lifting hook height can be quickly and accurately obtained only according to a conventional height sensor calibration mode, accurate data support is provided for tower crane collision prevention, and it is ensured that collision accidents do not occur when the tower crane is operated.
本发明提供一种动臂式塔机吊钩起升高度计算方法,属于塔机安全监控防碰撞技术领域,根据动臂式塔机起升钢丝绳穿绕方式以及吊钩起升原理进行分析,计算出起重臂架铰点离地高度距离、起重臂架变幅后引起的吊钩高度变化距离和吊钩与起重臂架底部之间的距离,然后计算动臂式塔机吊钩起升高度。本发明通过塔机出厂时按照不同动臂塔机型号内置好不同用作计算的静态参数,仅需按照常规的高度传感器标定方式,即可快速、准确得到实时的吊钩高度,为塔机防碰撞提供准确的数据支撑,确保塔机操作时不发生碰撞事故。
