A locking device for preventing an elevator from accidentally falling is used for safety protection for preventing the elevator from accidentally falling in the running process of the elevator and belongs to the technical field of manufacturing of auxiliary equipment for preventing the elevator from accidentally falling due to faults. The locking device comprises a gearbox and speed limiting mechanisms. Two gears which are engaged are rotationally arranged in the gearbox, and gear shafts of the gears are horizontal. Obliquely-downward connecting rods are fixedly connected to the positions, away from the engagement position, of the gears, the middle points between the two ends of the connecting rods are hinged to the tail ends of traction ropes of the speed limiting mechanisms, the ends, away from the gears, of the connecting rods are rotationally connected with sliding blocks, and the sliding blocks are connected with elevator guide rails in a sliding manner. By means of the locking device for preventing the elevator from accidentally falling, the manner that the gears are connected with the connecting rods is adopted, the elevator is prevented from falling accidentally in the manner of applying force through the connecting rods and increasing the friction force between the sliding blocks and the elevator guide rails, and the problem that an existing elevator safety anti-falling device is likely to be disturbed by external conditions due to the fact that electrical elements are adopted is solved.

    一种防止电梯意外下坠紧锁装置,用于电梯行驶过程中防止电梯意外下坠的安全保护,属于防止电梯发生意外故障坠落的辅助设备制造技术领域,齿轮箱、限速机构,所述齿轮箱内设有转动设有两个相互啮合的齿轮,所述齿轮的齿轮轴水平,所述齿轮上远离相互啮合处固定连接倾斜向下的连杆,所述连杆两端之间的中点铰接在限速机构的牵引绳的末端,所述连杆远离所述齿轮一端转动连接有滑块,所述滑块与电梯导轨滑动连接,本发明采用齿轮连接连杆的方式,通过连杆施力,增大滑块与电梯导轨之间的摩擦力的方式阻止电梯意外下坠,解决了现有的电梯安全防坠装置采用电气元件,容易受到外界条件干扰的问题。
