Digital monitoring system and adjusting method for rotary kiln riding wheel shaft bearing bush

Abstract

The invention discloses a digital monitoring system and adjusting method for a rotary kiln riding wheel shaft bearing bush. The digital monitoring system comprises a riding wheel, a riding wheel shaft, sliding bearings and bearing pedestals, wherein the two bearing pedestals are symmetrically arranged, the bearing pedestals are fixed to a supporting base, the sliding bearings are arranged in the bearing pedestals, the riding wheel is connected to the riding wheel shaft in an interference fit mode; and the riding wheel shaft acts on the sliding bearings, so that the riding wheel shaft and the riding wheel rotate freely; a thrust plate and an oil spoon are arranged on the two sides of the riding wheel shaft, a temperature sensor is arranged on the sliding bearing, a camera is arranged on the bearing seat, the camera corresponds to the thrust plate in position, and the temperature sensor and the camera are electrically connected with a PLC of the rotary kiln. The digital adjustment method for the rotary kiln riding wheel shaft bearing bush mainly comprises the three steps of monitoring data acquisition, data analysis and riding wheel adjustment, real-time monitoring is achieved, feedback is timely, adjustment is rapid, and normal operation of production is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of monitoring and maintenance of bearing pads of a rotary kiln, in particular to a digital monitoring system and an adjustment method for a bearing pad of a supporting wheel shaft of a rotary kiln. Background technique [0002] When the rotary kiln is in operation, due to factors such as temperature, feeding amount, and operating speed, the kiln body moves up or down on the surface of the supporting wheel, and the relative displacement of the supporting wheel shaft and the supporting wheel bearing bush causes the end surface of the bearing bush to rub against the end surface of the bearing bush and is forced to stop. In the kiln, the heating temperature of the bearing bush is as high as 120-200°C. Frequent maintenance will result in a decrease in output and an increase in cost. Frequent high temperatures during operation will cause damage to the contact surface of the bearing bush and be forced to stop produc...

Problems solved by technology

In the existing operation process, manual monitoring is mostly used. Every two hours, the operator uses a flashlight to observe the gap between the bearing bushes. This operation method has the problems of large visual errors and is laborious.
