Special vertical ladder for fire fighting

Abstract

The invention provides a special vertical ladder for fire fighting. A pin base is fixed on a base, a rotary pin is connected with the pin base and a rotary base, the angle between the base and the rotary base is adjusted through a gravity cone and locked with a locking screw, an external conical surface of the lower end of each supporting column body is matched with the rotary base or an internal conical surface of an internal conical hole of a supporting column body below to be fixed, and each internal conical surface and the corresponding external conical surface which are well attached are automatically locked through matching of an annular braking groove in the corresponding external conical surface and a corresponding rotating pin after the corresponding internal conical hole and the corresponding external conical surface are matched and well fixed. Folding pedals capable of being folded in one end, provided with a connector, of each supporting column body are fixed on the surface of the corresponding supporting column body, and anti-sliding glue is applied to the bottom of the base. The special vertical ladder for fire fighting is simple in structure and very convenient to manufacture, assemble, use and carry, tools are not required in assembly and disassembly processes when the ladder is used, the vertical climbing and standing problem of fire fighters during fire fighting or rescuing is solved, the ladder assembly speed is high when the fire fighters climb, and the ladder is safe, reliable and convenient to climb and is convenient to disassemble, pack and transport after used.

Description

technical field [0001] The invention relates to a special upright fire ladder for upright climbing of firefighters during firefighting, emergency rescue and rescue. Background technique [0002] The fire ladders used by firefighters are basically folding fire ladders, which are large and long, which are not conducive to firefighters to carry, and are laborious when opening and placing the ladders. Contents of the invention [0003] The purpose of the present invention is to provide a special-purpose upright fire ladder which is convenient for carrying, placing, assembling and climbing, and its manufacture and method. [0004] In order to achieve the above object, the special upright fire ladder of the present invention includes a base, a pin seat, a rotating pin, a locking screw, a rotating seat, a gravity cone, a pillar body, an outer cone surface, an inner cone hole, an inner cone surface, a brake device; [0005] The special-purpose upright fire ladder is a single-col...
