The invention discloses an adjustable centrifugal overspeed protection device for a coal mine monorail crane, relates to the technical field of monorail crane locomotives, and aims to solve the problems that an existing monorail crane is single in braking structure, braking treatment on the monorail crane is difficult to finish twice or even three times under the condition that the monorail crane is excessively abraded or damaged; the monorail crane comprises two trolley shells, and the two trolley shells are arranged on the trolley shell. In the using process, the first protection assembly and the second protection assembly can be subjected to multiple times of speed reduction treatment with the sliding assembly, and the situation that the first protection assembly or the second protection assembly cannot effectively finish speed reduction treatment on the sliding assembly is avoided; and if the interior of the pressure assembly or the adjusting assembly is damaged and effective gas circulation cannot be formed, the third protection assembly also completes locking treatment on the sliding assembly, it is further ensured that the device can effectively protect the trolley mechanism when the trolley mechanism overspeeds, and the safety of the device in use can be improved through the arrangement of multiple insurance.
本发明公开了一种可调式煤矿单轨吊离心超速保护装置,涉及单轨吊机车技术领域,旨在解决现有的单轨吊制动结构单一,难以实现在其过度磨损或损坏的情况下二次甚至三次对单轨吊完成制动处理,限制现有单轨吊使用时安全性的技术问题,包括两个小车壳体。本发明在使用过程中不仅可以通过第一保护组件和第二保护组件分别与滑动组件进行多次减速处理,避免第一保护组件或第二保护组件无法有效完成对滑动组件的减速处理,若压力组件或调节组件内部破损无法形成有效的气体流通则第三保护组件也将完成对滑动组件的锁死处理,进一步确保了该装置在小车机构超速时可以有效对其进行保护处理,通过多重保险的设置可以提高该装置使用时的安全性。
