The invention discloses an oil sealing device for an escalator rolling wheel. The oil sealing device comprises a working platform. A pushing air cylinder is arranged at one end of the working platform. A pushing block is arranged at one end of a telescopic rod of the pushing air cylinder. An arc push block is arranged by being perpendicular to the pushing block. A sliding way is arranged at the position, on one side of the arc push block, on the working platform. An infrared induction switch is further arranged on the face, opposite to a gap on the sliding way, on the working platform. A sealing box body is arranged at the other end of the working platform. The sliding way extends into the sealing box body. Press plates for limiting the rolling wheel are obliquely arranged on the left side and the right side of the position, in the sealing box body, of the sliding way. A rotating wheel driven by a motor to rotate is arranged on one side of one press plate. An oil injection pipeline is arranged above the two p
