The invention discloses an anti-disengagement device for a hanging plate of a goods elevator door machine landing door system. The anti-disengagement device is installed on the goods elevator door machine landing door hanging plate. The landing door hanging plate is provided with hanging plate wheels and a hanging plate guide rail allowing the hanging plate wheels to roll. The anti-disengagement device comprises two anti-disengagement blocks and fastening bolts. The two anti-disengagement blocks are in a stepped shaft shape in appearance. Each anti-disengagement block is composed of three sections of coaxial cylinders with the diameters sequentially increased. A threaded hole allowing the corresponding fastening bolt to penetrate through is formed in the center of each anti-disengagement block. Two limiting holes are formed in the landing door hanging plate. The ends of the anti-disengagement blocks penetrate through the limiting holes and are connected with and fixed to the landing door hanging plate through the fastening bolts. By the adoption of the anti-disengagement device for the hanging plate of the goods elevator door machine landing door system, the two anti-disengagement blocks are installed, and no matter when the hanging plate bears positive impact or negative impact, impact loads can be directly transmitted to the guide rail through the anti-disengagement blocks. The hanging plate is prevented from disengaging from the guide rail. The structure is simple, machining, manufacturing, mounting and demounting are convenient, cost is saved, and the anti-disengagement device is convenient to use and practical.
