The invention discloses a steel wire rope lifting stroke measuring device which comprises a box body provided with a transmission module and a measuring module, wherein the whole box body is fixedly connected to the top end of a vertical lifting part of a steel wire rope through bolts and nuts. The transmission module converts up-and-down movement of the steel wire rope into rotation of a magnetic conductive gear at the tail end of a measuring wheel shaft through a measuring wheel in close contact with the steel wire rope. The measuring module measures the number of turns of rotation of the magnetic conductive gear through a Hall dual-channel sensor, converts a high-level signal into a digital signal through a wireless data transmission module, and wirelessly transmits the digital signal to an operation module mounted in an operation room for calculation. The operation module calculates an actual lifting distance of the steel wire rope through a formula, and finally a result is transmitted to a control panel
