The invention belongs to the technical field of hoist hoists, particularly relates to a hoop type safety redundant brake, and provides the following scheme aiming at the existing problems that the friction is too large, the loss is intensified, and the heat affects the structural performance: the hoop type safety redundant brake comprises a hoist shell and a winding drum rotationally sleeved in the hoist shell; half ratchet rings are bolted to the top and the bottom of the winding drum, the two half ratchet rings are bolted, the right sides of the half ratchet rings are bolted with wave-shaped wheels, the right side of the hoist shell is bolted with a rotating shaft, the surface of the rotating shaft is rotationally sleeved with a frame, the right side of the surface of the rotating shaft is bolted with a tension spring, the tension spring is bolted with the frame, and the top of the frame is bolted with a pawl; a rotating wheel is rotationally connected to the bottom end of the right side of the frame and can drive a transmission mechanism to rotate through a main bevel gear, and the transmission mechanism can drive a micro pump to operate through a small bevel gear. The micro pump can pump lubricating oil for lubrication, the structural friction is reduced, air can be fanned through the heat dissipation mechanism, heat dissipation is conducted, and heat accumulation is avoided.

    本发明属于葫芦起升机技术领域,尤其是一种箍型安全冗余制动器,针对现有的摩擦过大,加剧损耗,热量影响结构性能的问题,现提出如下方案,其包括葫芦外壳和葫芦外壳内部转动套接的收卷筒,所述收卷筒的顶部和底部均栓接有半棘轮圈,两个半棘轮圈之间栓接,半棘轮圈的右侧栓接有波形轮,葫芦外壳的右侧栓接有转轴,转轴的表面转动套接有框架,转轴表面的右侧栓接有拉簧,拉簧与框架栓接,框架的顶部栓接有棘爪;框架右侧的底端转动连接有转轮,转轮通过主锥齿轮可以带动传动机构转动,传动机构通过小斜齿轮可以带动微型泵运转。本发明中微型泵便能泵取润滑油进行润滑,减少结构摩擦,通过散热机构可以扇风,进行散热,避免热量蓄积。
