The invention discloses a vibration reduction device of a combined type hoisting device. The vibration reduction device comprises a fixed frame, an anti-swing box body, a first fixed pulley, a secondfixed pulley, a first buffer pulley, a second buffer pulley and a fixed pulley fixing frame. The first fixed pulley and the second fixed pulley are arranged on the fixed pulley fixing frame, and the anti-swing box body is connected with the lower end of the fixed pulley fixing frame. The fixed frame is fixedly connected with the fixed pulley fixing frame. A fixed base is arranged at the lower endof the fixed frame. A first buffer frame and a second buffer frame are arranged on the first buffer pulley and the second buffer pulley correspondingly. Limiting sliding blocks are fixedly connected to the first buffer frame and the second buffer frame correspondingly. Limiting sliding grooves are formed in the fixed frame. The limiting sliding blocks are connected with the limiting sliding grooves in a sliding mode. The vibration reduction device is novel in structural design, convenient to install, safe, reliable and capable of buffering and filtering vibration force and reducing damage of the vibration force to the hoisting device.
