[0001] The utility model relates to the technical field of measuring the slippage of a rotary kiln wheel belt, in particular to an automatic measuring device for the slippage of a rotary kiln wheel belt. Background Art

[0002] The current measurement of rotary kiln wheel slippage is still in the manual control mode on site. Since the daily slippage of the rotary kiln wheel is measured under normal operation of the kiln, the cylinder temperature of the rotary kiln is relatively high when the rotary kiln is running. During measurement, it is necessary to mark the kiln cylinder and the wheel. After the kiln cylinder rotates one circle, the displacement of the wheel relative to the kiln cylinder is measured. The slippage measurement is difficult, time-consuming and laborious, and the measurement data is inaccurate. The operating space at the rotary kiln operation site is small, high temperature radiation, etc., the conditions are harsh and even dangerous. At present, for the rotary kiln wheel slippage monitoring system of the cement plant, the wheel slippage control is extremely important. If the rotary kiln wheel slippage is not well controlled, it will seriously affect the normal operation of the rotary kiln, and affect the service life of the refractory bricks, and even cause serious damage to the rotary kiln carcass, causing property losses.
