The invention discloses a lifting rail anti-falling brake device which comprises a traction component. A lifting carrier is installed at the lower section or the lower end of the traction component, brake connecting rods are installed at the upper section of the traction component, one end of each brake connecting rod is connected to the upper section of the traction component through a rotating component, the other ends of the brake connecting rods are connected with brake blocks through rotating components, a brake pad used for making contact with a guide rail to conduct braking is mounted at one end of each brake block, the other ends of the brake blocks are connected with an elastic component, the elastic component is connected with the lower section of the traction component, and the traction component, the brake connecting rods, the brake blocks and the elastic component form a four-connecting-rod structure. According to the lifting rail anti-falling brake device, in the process that the traction component loses traction force and falls suddenly, the brake pads are driven through a four-connecting-rod mechanism, the brake pads are driven to rotate and achieve braking under the action of a tension spring, and the braking aim is achieved.
