A friction energy dissipation beam falling prevention device belongs to the technical field of quakeproofing and disaster reduction. The device comprises two fixed end assemblies which are connected with a bridge pier and a bridge beam respectively, two channel steel systems, a connection steel plate, and four rotation friction energy dissipation hinges. The fixed end assemblies are anchored on the bridge pier and the bridge beam by four pre-embedded high-strength bolts, each channel steel system comprises two channel steels which are backed up against each other, each rotation friction energy dissipation hinge comprises two annular steel sheets, two annular copper sheets and a high-strength bolt. The high-strength bolt sequentially passes through its corresponding annular steel sheet, annular copper sheet, channel steel extending steel plate of the fixed end assembly or the connection steel plate, channel steel, annular copper sheet and annular steel sheet to form the rotation friction energy dissipation hinge. When the bridge beam shifts relative to the bridge pier, the four hinge structures can freely rotate and prevent the beam from falling, and simultaneously the annular steel sheets, the annular copper sheets, the channel steels and the fixed end steel plates or the connection steel plate can also dissipate some energy during the rotation process.
