The invention relates to the technical field of escalators, and discloses an escalator auxiliary braking device which comprises an auxiliary braking assembly, a driving main shaft, a truss and a controller, the auxiliary braking assembly comprises a clamping driving structure, two main shaft clamping structures, two reset structures, a detection structure and a base, and the base is installed on the truss. One ends of the two main shaft clamping structures are hinged to the base, the two main shaft clamping structures are arranged in a mirror image mode, the driving main shaft penetrates through the position between the two main shaft clamping structures, the two ends of the driving main shaft are installed on the truss, and the other ends of the two main shaft clamping structures are connected with the two ends of the clamping driving structure correspondingly. The two ends of the two reset structures are connected with the other ends of the two main shaft clamping structures respectively, the clamping driving structure is installed on the truss, the detection structure is matched with the driving main shaft, and the clamping driving structure and the detection structure are both connected with the controller. The brake device is high in friction force controllability and stable in braking process, is provided with a closed-loop control system for monitoring the speed reduction process and dynamically adjusting the closing force, and has the advantages of being convenient to maintain and replace.
