The invention relates to a multifunctional connecting device of a special speed reducer for an escalator. The multifunctional connecting device comprises a motor installation structure and a motor brake structure. The motor installation structure comprises a motor base and a flexible coupling. The motor base comprises a motor installation plate and a supporting ring fixedly connected to one side of the base installation plate. The flexible coupling is installed in the supporting ring. Through holes are symmetrically formed in the two longitudinal sides of the supporting ring, and a brake installation plate is installed on one transverse side of the supporting ring. The motor brake structure comprises a brake ring installed in the supporting ring and brake arm assemblies longitudinally and symmetrically installed on the motor base. A brake disc is fixedly connected in the brake ring and fixedly connected with the flexible coupling and a worm shaft of the speed reducer, and the flexible coupling is fixedly connected with a motor shaft. Each brake arm assembly comprises a brake arm hinged to the motor installation plate and a brake pad installed on the brake arm, and the ends of the two brake arms are connected with a brake fixedly connected to the brake installation plate. The multifunctional connecting device is reasonable in structural design, small in installation space and low in cost.
