The portal frame comprises two supporting leg assemblies and a main transverse beam, a fixed pulley connecting frame is fixed to the middle of the main transverse beam, a fixed pulley is fixed to the lower portion of the fixed pulley connecting frame, and end connecting blocks are welded and fixed to the left end and the right end of the main transverse beam correspondingly; three inclined connecting pipes extending downwards in the inclined direction are fixed to the end connecting block, top connecting pipe parts are welded or formed at the bottom ends of the inclined connecting pipes, and top connecting flange plates are welded and fixed to the bottom ends of the top connecting pipe parts. The escalator protection frame can protect the movable pulley, the fixed pulley and the lifting hook below the main transverse beam, prevent other external objects from colliding with the movable pulley, the fixed pulley and the lifting hook and guarantee normal use of the escalator protection frame, and the inner reinforcing sleeve is arranged between every two adjacent sectional pipes in the branch legs, so that the strength of the joint of every two adjacent sectional pipes is enhanced, and the service life of the escalator protection frame is prolonged. And the support leg assembly is formed by fixing three branch legs and a plurality of connecting support beams.
