The invention relates to an erecting ladder for fire fighting. According to the erecting ladder, a pin seat is fixed on a base, a rotating pin is connected with the pin seat and a rotating seat, an angle between the base and the rotating seat is locked by a locking screw, an outer conical face of one supporting column body is matched with an inner conical hole of the rotating seat or an inner conical face of an inner conical hole of a next supporting column body so as to be fixed, and the corresponding inner conical face and the corresponding outer conical face, which are in fit, are automatically locked through enabling an annular stopping groove in the corresponding inner conical face and a locking end of a corresponding turning body to be matched with each other after the corresponding inner conical hole and the corresponding outer conical face are fixed in a matched manner; folded type pedals which can be folded towards the connector end of each supporting column body are fixed at the two sides of the surface of a columnar body of the corresponding supporting column body, and an anti-slip adhesive is adhered to the bottom of the base. The erecting ladder for fire fighting is simple in structure, very convenient to assemble and use and convenient to carry; during use, no tool is required during assembly and disassembly, and the difficult problems of upright climbing and standing for fire fighters during fire-fighting emergency and rescue are solved; during climbing, ladder assembling is high in speed and is safe and reliable, and the climbing is convenient; after use, disassembling, packaging and transporting are convenient.
