The invention relates to the field of crown blocks, in particular to a crown block limiting mechanism which comprises a crown block frame and a crown block body, a mounting plate is fixed to one side of the crown block body, a lifting hook set is arranged on the mounting plate, the lifting hook set is composed of a winding roll, a lifting rope and a hook, the lifting rope is wound around the winding roll, and the hook is arranged on the winding roll. And the other end of the lifting rope is fixed with the hook. According to the crown block limiting mechanism, a limiting assembly for deflection of the lifting rope in the lifting and moving process of the crown block body can be formed, and when the lifting rope inclines by a large angle due to stress, the fixing pipe is driven to continuously move upwards on the guide rod through transmission, so that the lifting rope is prevented from being deflected. At the moment, the position of the fixing pipe is recognized through a proximity switch on the second fixing plate, an alarm is given, an operator is reminded of the phenomenon that the deflection amount exceeds the limiting requirement in the traveling process of the crown block body, and speed reduction adjustment needs to be conducted in time, so that the safety of the crown block body in the using process is further improved.
本发明涉及天车领域,具体的说是一种天车限位机构,包括天车架及天车本体,所述天车本体的一侧固定有安装板,所述安装板上设置有吊钩组,所述吊钩组由卷线盘、吊绳及挂勾组成,所述吊绳卷设在卷线盘上,所述吊绳的另一端与挂勾相固定。本发明所述的一种天车限位机构,可以形成天车本体吊起移动过程中对吊绳偏摆的限位组件,当吊绳受力发生较大角度的倾斜时,通过传动,带动固定管在导向杆上持续的向上运动,此时通过第二固定板上的接近开关识别到固定管的位置并进行报警,提醒操作人员天车本体在行驶过程中存在偏摆量超过限位要求的现象需要及时降速调整,进一步的提高了天车本体使用过程中的安全性。
