The invention discloses an ejector rod fixing device for preventing a brake of a bridge crane from loosening, which comprises a fixing mechanism, the top of the fixing mechanism is movably connected with an electromagnet, the top of the electromagnet is fixedly connected with a fixing seat, the top of the electromagnet is fixedly connected with a pushing and stretching mechanism, and the top of the fixing seat is movably connected with a detection mechanism. The top of the fixing base is fixedly connected with an alarm device and movably connected with a switching mechanism. According to the ejector rod fixing device for preventing the brake from being loosened for the bridge crane, an electromagnet ejector rod is bent to drive a pressing plate to move, the pressing plate drives a push rod to move, the push rod drives a pressing block to move, the pressing block drives a sliding block to move, the sliding block drives a rotating block to rotate, the rotating block drives a magnet to rotate, and the magnet is close to an alarm base; induced current is generated in the induction coil according to the electromagnetic induction principle, the induced current is transmitted into the lamp holder, the lamp holder lightens the bulb after being powered on, the automatic detection and alarm functions are achieved, and the reliability and safety of equipment are improved.

    本发明公开了一种用于桥式起重机防止制动器不松闸的顶杆固定装置,包括固定机构,所述固定机构顶部活动连接有电磁铁,电磁铁顶部固定连接有固定座,电磁铁顶部固定连接有推伸机构,固定座顶部活动连接有检测机构,固定座顶部固定连接有报警装置,固定座顶部活动连接有切换机构。该用于桥式起重机防止制动器不松闸的顶杆固定装置,通过电磁铁顶杆弯曲带动压板移动,压板带动推杆移动,推杆带动压块移动,压块带动滑块移动,滑块带动转动块旋转,转动块带动磁铁旋转,磁铁靠近警报座,通过电磁感应原理在感应线圈中产生感应电流,感应电流传递到灯座中,灯座通电后点亮灯泡,实现自动检测和报警功能,提高设备可靠性和安全性。
