The invention belongs to the technical field of escalators, and discloses an escalator chain tensioning device which comprises a mounting base, a sliding support and a tensioning wheel. The mounting base comprises a first containing cavity, an elastic adjusting device is arranged at the top end of the first containing cavity, and a longitudinal sliding groove is formed in the outer wall, close to the bottom, of the first containing cavity; the sliding support comprises a second containing cavity, a sliding flange is arranged on the outer wall, close to the top, of the second containing cavity, and the sliding flange is inserted into the sliding groove in a sliding mode. A mounting hole is formed in the outer wall, close to the bottom, of the second containing cavity and fixedly connected with a tensioning wheel, and the tensioning wheel is of a gear structure, used for being meshed with a chain of the escalator and used for supporting and tensioning the chain under the elastic compression effect of the elastic adjusting device. According to the escalator chain tensioning device, the tensioning wheel is resistant to abrasion, operation noise is low, the structure is simple and compact, the occupied space is small, manufacturing, installation and maintenance are convenient, and the tensioning effect of the chain is good.
