| description | The utility model relates to a fatigue life test device for a main drive chain of an escalator. The driving rotating shaft and the driven rotating shaft are rotatably mounted; the first driving step, the transmission wheel and the second driving step are sequentially fixed on the driving rotating shaft; the first driven step, the driven wheel and the second driven step are sequentially fixed on the driven rotating shaft; the first driving step and the first driven step are connected through a first step chain; the second driving step and the second driven step are connected through a second step chain; the transmission wheel is connected with a driving motor through a transmission chain; the driven wheel and the load motor are connected through a test driving chain, the test driving chain and the first step chain are opposite in rotating direction, the first step chain and the second step chain detect chain extension and breakage through a chain extension and breakage detection mechanism, and the driving moto |
