The invention provides a crane brake protection device, and relates to the field of cranes, the crane brake protection device comprises a protection assembly, the protection assembly is composed of a trigger mechanism and a brake mechanism, the protection assembly has a normal brake mode and a protection brake mode, normal brake use of the protection assembly can be achieved through an electric push rod during normal brake, and the protection assembly is used for protecting the brake. The protection braking mode can control the state of a jack driving wheel during power failure, the protection braking function and mode can be automatically triggered when a lifting hook rapidly falls, hoisting assemblies such as the lifting hook of the crane are mechanically braked, the process is completely mechanically triggered, no external energy is needed, and the safety is high. The problem that a brake of an existing crane is braked in an electric control mode and does not have a mechanical protection structure for emergency situations, for example, when a heavy object is hoisted, if power failure and other situations occur, the brake cannot play a braking role in time, and the heavy object falls off is solved.

    本发明提供一种起重机的制动器保护装置,涉及起重机领域,包括:保护组件,所述保护组件由触发机构和制动机构组成,保护组件具有正常制动和保护制动两种制动模式,在正常制动时可通过电动推杆实现保护组件的正常制动使用,而保护制动模式能够在断电的时候控制起重器驱动轮的状态,其在吊钩快速下落时会自动触发保护制动功能和模式,机械式的将起重机的吊钩等吊运组件制动刹停,该过程完全机械式触发无需外部能源,解决了现有起重机的制动器是通过电动控制的方式实现制动的,其并没有紧急情况的机械式保护结构,例如在重物吊运时若如发生断电等情况可能导致制动器无法及时发挥制动作用导致重物跌落的问题。
