Anti-falling guardrail device and mounting method thereof

The invention relates to the field of rail fixing devices, in particular to an anti-falling guardrail device, an anti-falling support of the anti-falling guardrail device and an anti-falling buckle plate, and the anti-falling support comprises a support insulator and a metal structure support supporting body which are compounded into a whole through a rubber and plastic process. A first internal anti-disengagement piece and a first external anti-disengagement piece are arranged between the support insulator and the support supporting body, the anti-disengagement plate comprises a buckle plate insulator and a buckle plate supporting body of a metal structure, the buckle plate insulator and the buckle plate supporting body are compounded into a whole through the rubber and plastic technology, and a second internal anti-disengagement piece and a second external anti-disengagement piece are arranged between the buckle plate insulator and the buckle plate supporting body. The support insulator and the buckle plate
