The invention provides an escalator step roller loading test device. The escalator step roller loading test device comprises a roller loading driving disc, a roller force loading device, an oil pump device and a sensor detection device; the roller loading driving disc abuts against one side of the roller and is used for driving a roller to rotate; one end of the roller force loading device is rotatably connected with the roller, and a variable load is provided for the roller through pressure oil provided by the oil pump device; the oil pump device is used for providing the pressure oil for the roller force loading device; and the detection device is used for monitoring the variable load, the displacement deformation of the roller and the crack condition of the roller in real time. The roller force loading device and the oil pump device are used for providing the variable load for the roller, the roller force loading device and the oil pump device form a hydraulic transmission mechanism, and compared with a motor transmission mechanism, the hydraulic transmission mechanism is not prone to abrasion after being used for a long time due to the lubrication effect of the pressure oil in the hydraulic transmission mechanism.
本发明提供一种自动扶梯梯级滚轮加载测试装置,包括:滚轮加载驱动盘、滚轮力加载装置、油泵装置和传感器检测装置;所述滚轮加载驱动盘,抵接在所述滚轮的一侧,用于带动所述滚轮进行转动;所述滚轮力加载装置,其一端转动连接有所述滚轮,通过油泵装置提供的压力油向所述滚轮提供可变载荷;所述油泵装置,用于向滚轮力加载装置提供压力油;所述检测装置,对所述可变载荷、所述滚轮的位移变形和所述滚轮的裂纹情况进行实时监测。本发明通过滚轮力加载装置和油泵装置为滚轮提供可变载荷,滚轮力加载装置和油泵装置组成液压传动机构,相比电机传动机构,液压传动机构由于其内部压力油的润滑作用,使得液压传动机构在长时间使用时不易发生磨损。
