The invention belongs to the technical field of tower crane bolt looseness early warning and recognition, and particularly discloses a tower crane bolt looseness prevention alarm system which comprises the steps that by recognizing the gravity center position of an object on a tower crane boom, the bolt looseness situation is recognized according to the difference of the gravity center position of the object, and the tower crane bolt looseness prevention alarm system is obtained; the potential safety hazard of bolt looseness can be found more accurately; by analyzing the corresponding displacement stability response of the carrying movement track of the tower crane boom and the torque looseness degree of each connecting bolt corresponding to each standard knot, the looseness possibility of the bolts is checked from the carrying dimension of the boom; a plurality of factors such as a wind direction stress resonance layer, a vibration abnormal sound layer and a corrosion mottle layer are comprehensively considered, and the loosening possibility of the bolt is inspected from the wind load characteristic dimension; the corresponding positions of the loosened bolts are positioned by constructing the loosening tendency relational expression of the corresponding connecting bolts of the standard knots of the tower crane, and a more accurate and effective maintenance plan can be made according to real-time data and analysis results.
本发明属于塔吊螺栓的松动预警识别技术领域,具体公开提供的一种塔吊防螺栓松动报警系统,该系统包括:通过识别塔吊起重臂上载物重心位置,针对载物重心位置差异进行螺栓松动情况的识别,可以更精确地发现螺栓松动的潜在安全隐患;通过分析塔吊起重臂的运载移动轨迹相应位移稳定响应、各标准节相应各连接螺栓的力矩松动度,从起重臂载物维度检验了螺栓的松动可能性;综合考虑风向受力共振层面、振动异响层面、锈蚀斑驳层面多个因素,从风载荷特征维度检验螺栓的松动可能性;通过构建塔吊各标准节相应各连接螺栓的松动倾向关系式,定位出松动螺栓相应位置,有助于根据实时的数据和分析结果来制定更加精准和有效的维护计划。
