The invention discloses a composite material cantilever type rigid supporting device which comprises a pair of cantilever base body structures distributed up and down, an inclined cantilever is installed on the front side of the cantilever base body close to the upper side, a flat cantilever is installed at the front end of the cantilever base body close to the lower side, and a cantilever connecting sleeve is inserted into the front end of the inclined cantilever; the cantilever type rigid supporting device is characterized in that a cantilever connecting sleeve is arranged on the front side of the cantilever, a sleeve double-lug is movably installed on the front side of the cantilever connecting sleeve, and the sleeve double-lug is fastened to the outer ring face of a flat cantilever and connected with the flat cantilever. A composite material cantilever type rigid supporting system is a novel rigid supporting system based on a high-performance fiber reinforced polyurethane composite material cantilever and is used for an electrified railway rigid suspension contact network. The performance advantages of polyurethane composite materials in the aspects of light weight, strength, insulation performance, corrosion resistance, pollution resistance and the like are utilized, and a metal cantilever and insulator combined structure adopted by an existing rigid contact net system is replaced.
