The invention provides a step chain driving device with sound attenuation and shock absorption functions. The step chain driving device comprises a step chain wheel (1) and step chain rollers (2). The step chain driving device is characterized in that at least one row of shock absorption rubber is installed at the meshing starting point and the demeshing point of the step chain rollers and step chain wheel tooth grooves. Compared with the prior art, the step chain driving device has the following advantages that the functions of sound attenuation, shock absorption and prolongation of the service life of a transmission part are achieved; machining and installing cost is low, the structure is simple, and installation and replacement are convenient; according to different ladder types and working conditions, different shock absorption rubber installing and arranging modes are customized through calculation of impact force of the chain rollers and the compression shock absorption capacity of the shock absorption rubber.
