The invention discloses an elevator safety gear-speed governor linkage device which comprises a support, a rotation driving device, a rotation shaft, a linkage mechanism, safety gear mechanisms, a speed detection mechanism and a controller, the safety gear mechanisms are arranged at the two ends of the support in pairs and comprise bases, control shafts and safety gear blocks, the control shafts are rotationally connected with the bases, and the speed detection mechanism is connected with the speed detection mechanism. The control shaft is provided with a worm matched with a worm gear of the base, the worm gear drives the safety tongs wedge block through a pull rod, the two sides of the rotating shaft are connected with the connecting arms through linkage mechanisms respectively, the rotating driving device pulls down or lifts up the control arm to enable the control shaft to rotate when driving the rotating shaft to rotate, and the safety tongs block is driven to be closed or separated. The speed detection mechanism is connected with the controller and used for detecting the speed and/or acceleration of the elevator car, and the controller is connected with the rotation driving device to control the rotation driving device to rotate forwards or backwards. Non-contact resetting of the safety tongs is achieved, operation of maintainers is facilitated, and safety guarantee is improved.

    本发明公开了一种电梯安全钳‑限速器联动装置,包括支架、转动驱动装置、转动轴、联动机构、安全钳机构、速度检测机构和控制器,安全钳机构成对设置于支架的两端,包括基座、控制轴和安全钳块,控制轴与基座转动连接,控制轴加工有蜗杆与基座的蜗轮配合,蜗轮通过拉杆带动安全钳楔块,转动轴的两侧分别通过联动机构与连接臂连接,转动驱动装置驱动转动轴转动时下拉或上抬控制臂使控制轴转动,驱动安全钳块合拢或分离,速度检测机构与控制器连接用于检测电梯轿厢的速度和/或加速度,控制器与转动驱动装置连接控制转动驱动装置正转或反转。本发明实现了安全钳的无接触复位,方便检修人员操作,提高安全保障。
