The linkage type emergency alarm device comprises the lift car, a containing groove is formed in the outer wall of the bottom of the lift car, an emergency braking mechanism is arranged on the outer wall of the bottom of the lift car, and the emergency braking mechanism comprises a hydraulic supporting unit, a magnetic attraction maintaining unit and an emergency power supply mechanism. The hydraulic supporting unit and the magnetic attraction maintaining unit are installed on the inner wall of the containing groove, the emergency power supply mechanism is fixedly connected with the outer wall of the bottom of the lift car, limiting maintaining mechanisms are arranged on the outer walls of the two sides of the lift car correspondingly, and alarm sensing mechanisms are arranged in the limiting maintaining mechanisms. When an elevator cannot run normally due to the sudden power failure condition, the electromagnetic block is clamped in the limiting and maintaining mechanism through electromagnetic adsorption, so that the elevator can be slowed down and hovered, the electromagnetic block is limited to clamp and clamp the limiting and maintaining mechanism through the linkage device, and the personal safety of personnel in the elevator car can be guaranteed under the emergency power failure condition.
