The invention discloses an overspeed braking device for a crane drum, and belongs to the technical field of cranes, the overspeed braking device comprises a drum assembly, braking assemblies are mounted on the outer sides of the two ends of the drum assembly, bottom plates are mounted below the braking assemblies, and gear assemblies are mounted above the two bottom plates and located between the two braking assemblies; a driving heat dissipation device is mounted between the two bottom plates; by arranging the driving heat dissipation device, heat dissipation and cooling can be conducted on structures such as a gear assembly through rotation of fan blades when the device works, the cooling speed can be increased through all refrigeration rods when needed, and then the durability of the device is improved; by arranging the lubricating and cooling device, the device can cool fierce friction heat generated during braking by spraying cooling liquid when needed, so that the possibility that the device is damaged is reduced, and the practicability of the device is improved.

    本发明公开了一种起重机卷筒的超速制动装置,属于起重机技术领域,包括卷筒组件,所述卷筒组件的两端外侧均安装有制动组件,制动组件的下方安装有底板,两个底板的上方且位于两个制动组件之间的位置均安装有齿轮组件,两个底板之间安装有驱动散热装置;本发明通过设置驱动散热装置,使得装置能够在工作的时候通过扇叶的转动对齿轮组件等结构进行散热降温,且能够在需要的时候通过各个制冷棒加快降温的速度,进而提高了装置的耐用性;本发明通过设置润滑冷却装置,使得装置能够在需要的时候通过喷洒冷却液对制动时剧烈的摩擦生热进行降温,从而降低了装置出现受损情况的可能,进而提高了装置的实用性。
