The invention provides a centrifugal block throwing-out device in operation of a speed limiter, and belongs to the technical field of speed limiters, the centrifugal block throwing-out device comprises a base and a bottom plate, the bottom plate is connected with a limiting rod and a fixing shaft, a rope wheel is arranged in the bottom plate, the side wall of the rope wheel is fixedly connected with an extension plate, and the centrifugal block throwing-out device further comprises a brake assembly used for locking the rope wheel; the centrifugal triggering assembly completes braking of the rope wheel through centrifugal force; the manual triggering assembly is used for completing braking of the rope wheel through external limiting; the beneficial effects of the invention are that external force is applied to the driving lever to drive the blocking wheel to move towards one side of the connecting rod, then the centrifugal block is triggered through interaction force to complete work, so that manual inspection is completed, the structure is simple, the application range is improved, the device can be carried about, and the device can be conveniently operated under the condition that the device does not actually run at an overspeed. The trigger function of the speed governor is verified, and the safety and convenience of maintenance work are improved.
本发明提供了一种限速器运行中的离心块甩出装置,属于限速器技术领域,包括底座和底板,底板连接有限位杆和固定轴,底板的内部设有绳轮,绳轮的侧壁固定连接有延伸板,还包括:制动组件,制动组件用于对绳轮的锁止;离心触发组件,离心触发组件通过离心力完成对绳轮的制动;手动触发组件,手动触发组件通过外界限位来完成对绳轮的制动;该发明有益效果:通过对拨杆施加外力,可带动抵挡轮向连杆一侧运动,随后通过相互作用力来触发离心块完成工作,以此来完成人为手动检验,且结构简单,提高适用范围,并且可随身携带,能够在不使设备实际超速运行的情况下,对限速器的触发功能进行验证,提高了维护工作的安全性和便利性。
