The invention discloses a stable portal frame for a foundation pit-free elevator. The stable portal frame comprises a gantry main body, a lubricating mechanism and a reinforcing mechanism. A guide rail is arranged on the inner surface of the bottom end of the gantry main body. A guide pipe is arranged on the portion, located on one side of the guide rail, of the inner surface of the bottom end ofthe gantry main body. The guide rail penetrates the guide pipe. The lubricating mechanism is located in the position, connected with the guide pipe, of the guide rail. The lubricating mechanism comprises a rotating disc. The rotating disc penetrates the surface of one side of the guide pipe. One side of the rotating disc is located on the outer side of the guide pipe. A piston cylinder is arrangedon the portion, located on one side of the rotating disc, in the guide pipe. By arranging the rotating disc, the surface of the guide rail can be lubricated, the service life of the guide rail and the guide pipe is prolonged, and it is guaranteed that a manual chain hoist can be freely adjusted in position within a certain periphery; and by arranging a sealing sleeve, connection of a vertical fixing shaft and a connecting seat can be reinforced, and the normal rotating function of a second hanging ring can be guaranteed.
