The invention discloses a deflection protection device for a shipbuilding portal crane. The shipbuilding portal crane deflection protection device comprises a lower connecting base, a shifting fork, a connecting rod supporting assembly, a connecting rod assembly, a pointer, a pointer supporting sliding way, a dial and a limiting switch, one end of the shifting fork is rotatably arranged on the connecting base, one end of the connecting rod assembly is rotatably connected with the shifting fork, and the connecting rod supporting assembly is used for supporting the connecting rod assembly; the pointer is rotatably arranged at the other end of the connecting rod assembly, the pointer supporting slide way is used for supporting the pointer to slide, the dial is arranged at the front end of the pointer and used for displaying the deviation angle of the pointer, and the limiting switch is arranged on the dial to remind the deviation angle. Rotation movement is collected, front-back tilting movement and left-right tilting movement are filtered, interference is avoided, and the safety of the crane is effectively improved.

    本发明公开了一种造船门式起重机偏斜保护装置。造船门式起重机偏斜保护装置包括下连接座、拔叉、连杆支撑组件、连杆组件、指针、指针支撑滑道、刻度盘和限位开关,拔叉一端可转动的设置在连接座上,连杆组件一端与拔叉转动连接,连杆支撑组件用于支撑连杆组件,指针可转动设置在连杆组件另一端,指针支撑滑道用于支撑指针滑动,刻度盘设置在指针前端用于显示指针偏移角度,限位开关设置在刻度盘上对偏斜角度进行提醒。本发明采集旋转运动,对前后倾、左右倾运动进行了过滤,避免了干扰,有效提高了起重机的安全性。
