The invention discloses a cordless type speed-limiting safety gear in the technical field of safety tongs, the cordless type speed-limiting safety gear is integrally installed on an elevator car and moves along with the elevator car, the speed-limiting safety gear comprises a safety gear assembly and a centrifugal mechanism, the safety gear assembly comprises a safety gear outer support, the safety gear assembly is installed in the safety gear outer support, and the centrifugal mechanism is arranged in the safety gear outer support. The safety gear assembly slides on the guide rail, the centrifugal mechanism comprises a flywheel shell, a centrifugal assembly is arranged in the flywheel shell, and the rope-free speed-limiting safety gear is lower in maintenance cost and lower in interference factor. The centrifugal mechanism and the elevator car can move synchronously through the friction roller, the moving speed of the elevator car is synchronized into the centrifugal assembly, and when the speed of the elevator car exceeds a preset value, the centrifugal assembly can lock the flywheel shell, so that the flywheel shell drives the safety tongs assembly to conduct brake speed limiting operation through the lifting rod.
本发明公开了安全钳技术领域的无绳式限速安全钳,其整体安装在电梯轿厢上,跟随轿厢移动,限速安全钳包括安全钳组件以及离心机构,所述安全钳组件包括安全钳外支座,所述安全钳组件安装在安全钳外支座内部,所述安全钳组件在导轨上进行滑动,所述离心机构包括飞轮壳体,所述飞轮壳体内部设置有离心组件,本发明为无绳式的限速安全钳,其维护成本更小,受干扰因素较低。通过设置离心机构可以通过摩擦滚轮与电梯轿厢进行同步移动,将电梯轿厢的移动速度同步到离心组件中,当出现电梯轿厢速度超过预设值时,离心组件可以锁住飞轮壳体,使得飞轮壳体通过提拉杆带动安全钳组件进行刹车限速操作。
