The invention discloses a car frame lifting mechanism, relates to the technology of elevators, and aims to solve the problems that existing car frame safety tongs are uneven in stress and prone to malfunction to cause accidents. According to the technical scheme, the car frame lifting mechanism is characterized in that the car frame lifting mechanism comprises a car body, an upper beam fixedly connected to the top of the car body and a lower beam fixedly connected to the bottom of the car body; the car frame lifting mechanism further comprises four safety tongs and a speed limiter used for controlling the safety tongs to act, the four safety tongs are arranged at the positions, located at the two sides of the upper beam and the two sides of the lower beam, on the car body, pull rods are arranged at the two sides of the car body, the two ends of each pull rod are fixedly connected with the corresponding safety tongs through fine adjustment assemblies, and lifting arms are arranged on the portions, located at the two sides of the car body, of the upper beam; and the lifting arms are in transmission connection with the pull rods, a linkage rod is further arranged on the upper beam, the two ends of the linkage rod are hinged to the lifting arms located at the two sides of the car body respectively, and reset assemblies used for resetting the safety tongs are arranged between the lifting arms and the pull rods. By means of the car frame lifting mechanism, synchronous linkage of the four safety tongs is achieved, a good braking effect is achieved, and meanwhile, the safety coefficient is increased.
