The invention discloses a crane capable of preventing a lifting hook from rushing to the top, and relates to the technical field of cranes. A trolley is slidably connected to the middle of the main beam, a winch is arranged in the middle of the trolley, and a lifting hook is wound at the lower end of a winch steel wire rope; the detection unit comprises sliding seats, guide columns, supporting pipes, detection pipes and first proximity switches, the sliding seats are arranged at the left end and the right end of the trolley respectively, the guide columns are slidably connected into the sliding seats, the first proximity switches are arranged at the left end of the trolley, the guide column on the left side is matched with the first proximity switches, and the supporting pipes are arranged at the lower ends of the guide columns. According to the crane capable of preventing the lifting hook from top rushing, when the crane is used, the second proximity switch and the first proximity switch can be used for conducting double detection on the top rushing action of the lifting hook, a large buffering distance is achieved, meanwhile, the second proximity switch and the first proximity switch can be self-detected before starting up, and the lifting hook is prevented from top rushing. And the use safety of the crane is greatly improved.
本发明公开了一种防止吊钩冲顶的起重机,涉及起重机技术领域,包括主梁和检测单元;主梁:其中部滑动连接有小车,小车的中部设有卷扬机,卷扬机钢丝绳的下端缠绕连接有吊钩;检测单元:其包括滑座、导向柱、支撑管、检测管和接近开关一,所述滑座分别设置于小车的左右两端,滑座的内部均滑动连接有导向柱,接近开关一设置于小车的左端,左侧的导向柱与接近开关一配合设置,导向柱的下端均设有支撑管,两个支撑管之间安装有检测管,该防止吊钩冲顶的起重机,使用时可以利用接近开关二和接近开关一对吊钩的冲顶动作进行双重的检测,且有较大的缓冲距离,同时开机前可以对接近开关二和接近开关一进行自检,大大提高了起重机使用时的安全性。
