The invention relates to a safety reset type linkage control elevator speed limiter, which is characterized in that a centrifugal mechanism is in contact with and presses a brake disc when an elevator is in a stall state, a linkage piece fixedly connected with the brake disc in the elevator speed limiter drives a linkage rod to lift so as to drive a hook plate to unhook, and the linkage rod is triggered when the elevator speed limiter triggers an action state; the brake disc comprises a brake drum concentric with the main shaft, a friction plate and a disc spring are arranged in the brake drum, a pull rod pin is welded to the outer side surface of the brake drum, the outer end of the pull rod pin is fixedly connected with a linkage plate, the outer side surface of the brake drum is covered with a limiting plate, and the limiting plate is fixedly connected with the brake drum. A copper plate and a check ring are sequentially arranged between the brake drum and the limiting plate from inside to outside. The device is small in size, convenient to arrange and higher in working stability and safety, the rope gripper is convenient to reset, tension is adjustable, different working condition requirements can be met, and reset potential safety hazards are low.
本发明涉及一种安全复位型连动控制的电梯限速器,其中,离心机构在电梯失速状态下接触压迫制动盘,该电梯限速器中与制动盘固定连接的连动片带动连动杆提拉,进而带动钩板脱钩,连动杆在电梯限速器触发动作状态时同时被触发,带动钩板动作、切换夹绳器的工作状态至夹持钢丝绳,其中,制动盘包括与主轴同心设置的制动鼓,制动鼓内设置有摩擦片与碟簧,制动鼓的外侧表面焊接有拉杆销,拉杆销的靠外一端固定连接连动片,制动鼓的外侧表面上盖设有限位板,在制动鼓与限位板之间由内至外依次设置有铜板以及挡圈。本申请体积小,便于布置,作稳定性及安全性更高,其中夹绳器的复位方便,且张力可调,能够满足不同的工况需求,且复位安全隐患低。
