The invention relates to a crane on-line balance detection device and a judgment method, the detection device comprises a portal frame inclination warning mechanism and a power cut-off mechanism after the warning is invalid, the real-time inclination judgment of a portal frame is formed through the arranged detection device, and the warning and the power cut-off action after the warning is invalid are formed according to the real-time inclination judgment. And the major accident that the hung object falls off after misoperation or neglect of the first-level warning is avoided. According to the crane on-line balance detection device and the judgment method, the on-line hoisting state of the crane is monitored in real time, and automatic judgment, automatic warning and power-off protection are set for abnormity generated in the hoisting operation process of current large hoisting equipment; a judgment, early warning and self-protection intervention mechanism for abnormal situations occurring at the initial lifting stage of the crane is formed; the problem that a plate hook jacks a shaft due to human judgment errors during hoisting of a crane can be effectively solved, the hoisting safety operation rate is improved, and the falling accident of a hoisted object is effectively avoided.
一种起重机在线平衡检测装置及判定方法,其检测装置包括有龙门架倾斜警示机构及警示无效后的切断电源机构,其方法通过设置的检测装置形成对龙门架的实时倾斜判定,并根据实时倾斜判定形成警示及警示无效后的切断电源动作,避免在操作失误或在忽视一级警示后防止吊物坠落的重大事故发生。本发明的一种起重机在线平衡检测装置及判定方法,对起重机在线吊运状态进行实时监控,针对目前大型起重设备吊运作业过程中产生的异常设定自动判别、自动警示及断电保护;形成对起重机在吊运初期时发生的异常情形进行判断以及预警和自保护介入机制;能有效解决起重机在吊运时由于人为判断失误导致的板钩顶轴问题,提高起重安全作业率,并有效避免被吊物坠落事故。
