PROBLEM TO BE SOLVED: To provide a swivel chute inner surface wear inspection device and a swivel chute inner surface wear inspection method capable of quantitatively and efficiently performing a swivel chute inner surface wear inspection at an arbitrary time. SOLUTION: A swivel chute inner surface wear inspection device 9 is a device for inspecting wear on the surface of a liner 32 stretched on the inner surface of a chute 21 installed in a charging device 20 of a blast furnace 10, and is inside the blast furnace 10. A non-contact type distance measuring device 42 that can be introduced into the liner 32 and can measure the measured distance to the surface of the liner 32, and a wear determination that determines the wear of the surface of the liner 32 based on the measured distance measured by the distance measuring device 42. As a distance measuring device 42 having a unit 52, a measuring beam for measuring a microwave or a millimeter wave is irradiated to measure the three-dimensional shape of the charged surface 24 charged in the blast furnace 10. The vessel 40 can also be used. [Selection diagram] Fig. 1
