The invention discloses an escape and transporting device for tall buildings. The device comprises a support frame, at least one pair of straight arm and an oblique pulling column, wherein all unit parts are fixedly arranged on the support frame; the at least one pair of straight arm extends outward; the oblique pulling column is used for supporting the straight arm; a main shaft and a rocking handle shaft are arranged on the straight arm and the oblique pulling column respectively, and at least one end of the rocking handle shaft is provided with a rocking handle; a pair of left chain wheel and right chain wheel for transmission are sleeved on the rocking handle shaft and the main shaft respectively, and the two chain wheels are interlinked by a chain; a unidirectional rotating mechanism with a flying wheel and a reel for recovering and releasing ropes are sleeved on the main shaft respectively, the two side walls of the reel are fixedly connected with the flying wheel of the unidirectional rotating mechanism and the right chain wheel for transmission respectively so as to realize linkage; and an intermittent mechanism capable of controlling the descent speed of a transported object is arranged on one side of the support frame or intermittent mechanisms capable of controlling the descent speed of the transported object are symmetrically arranged on both sides of the support frame, and a spring mechanism can also be arranged beside the intermittent mechanism. The escape and transporting device for the tall buildings can realize low descent speed for safe landing and can also meet the using requirements of multiple persons on circular escape.
