An axial light sensing type deflection monitoring apparatus for a hoist braking disc, comprising a base (10) and a sliding rod (14). The sliding rod (14) can slide in a central axis direction of the base (10). A light source generating unit and a light source receiving unit are symmetrically disposed on the inner sides of two side walls of the central axis of the base (14). Square holes, namely first light-transmitting holes (25) and second light-transmitting holes (22) having the same size in the same axis are provided on two opposite side faces of the light source generating unit and the light source receiving unit. Square through holes (24) as large as the square holes are provided on the sliding rod (14). By converting axial jumping of a hoist braking disc into movement of square through holes on a sliding rod, an axial jumping value of the braking disc is obtained using a light sensing principle, and a deflection quantity of the hoist braking disc is obtained by conversion. The deflection of the hoist braking disc can be monitored in real time. The apparatus can monitor, without changing an original hoisting device, a deflection situation of the hoist braking disc in real time, and can monitor the state of the hoist braking disc.
