The invention discloses an insertion type upright fire-fighting ladder. A base plate of the insertion type upright fire-fighting ladder is matched with the outer conical surface of the lower end of a ladder cylinder through an inner conical hole formed in the middle so as to be fixed; the outer conical surface of the ladder cylinder is matched with the inner conical surface of the inner conical hole in the ladder cylinder so as to be fixed; after the inner conical hole and the outer conical surface are matched and fixed, locking slots in the inner conical surface are matched with braking pins to automatically lock the inner conical surface and the outer conical surface which are attached; foot pedals are fixed on the cylinder surface of the ladder cylinder; antiskid rubber is adhered to the foot pedals; antiskid rubber is adhered to the bottom of the base plate. The insertion type upright fire-fighting ladder is simple in structure and is very convenient to assemble and use; tools are not needed in an assembling and disassembling process during use; by adoption of the series connection type upright fire-fighting ladder, the difficulty of upright climbing of a fire fighter is solved; during upright climbing, the fire-fighting ladder can be quickly, conveniently, safely and reliably assembled, and the climbing is convenient; after being used, the insertion type upright fire-fighting ladder is convenient to detach, package and transport, so that the production cost and the use cost are reduced.
