The invention discloses a monitoring method for hooking a lower container through a lifting appliance or a container carried by the lifting appliance during container lifting. Four spin locks are arranged on the lower surface of the lifting appliance, cameras or laser radar are arranged at four corners of the lifting appliance, the cameras or the laser radar are connected with a controller, and the controller is connected with a lifting mechanism. The cameras or the laser radar detects a lock hole or a container corner edge line at the top of a ground stockpiling container below the lifting appliance or the container carried by the lifting appliance, and when the empty lifting appliance or the lifting appliance carrying the container is lifted, whether the empty lifting appliance is hookedwith the container below the lifting appliance or whether the container grabbed by the lifting appliance is hooked with the ground stockpiling container or not is judged. Sensors are adopted for detection, so that it is sufficiently guaranteed that a gantry crane can stop working and give an alarm in the hoisting process of the gantry crane even if the lifting appliance is hooked with the container below the lifting appliance or the container grabbed by the lifting appliance is hooked with the ground stockpiling container, and the accidents that the hooked container accidentally falls off andhits the ground halfway, and bowling caused by the hooked container during the transverse movement of the lifting appliance with the container is avoided.
本发明公开了集装箱起吊时吊具或吊具所带集装箱勾连下方集装箱的监控方法,吊具的下表面设有四个旋锁,吊具上四个角装有摄像头或激光雷达,摄像头或激光雷达连接有控制器,控制器连接有起升机构;摄像头或激光雷达检测吊具或吊具所带集装箱下方地面堆存集装箱箱顶的锁孔或箱角边缘线,在空吊具或吊具带箱拉升时,判断空吊具是否存在勾连吊具下方的集装箱,或吊具所抓集装箱是否存在勾连地面堆存的集装箱。采用上述传感器进行检测,充分保证了龙门吊起吊过程中,即便存在吊具勾连吊具下方的集装箱,或吊具所抓集装箱勾连地面堆存的集装箱,龙门吊会暂停工作并报警,避免意外勾连箱中途脱落砸地面,及勾连箱在吊具带箱横移导致打保龄的事故发生。
