Gap measuring device for thermal state tyre of cement rotary kiln, and application method for gap measuring device

Abstract

The invention provides a gap measuring device for a thermal state tyre of a cement rotary kiln, and the gap measuring device comprises a cement rotary kiln barrel and a kiln tyre. The gap measuring device is characterized in that a marking body which is disposed at an interval with the cement rotary kiln barrel and can mark a travel track, a telescoping sleeve structure which is connected with themarking body and can control the stretching and withdrawing of the marking body, a connecting structure which is connected between the cement rotary kiln barrel and the telescoping sleeve structure and a track mark presenting device which is connected to the kiln tyre are disposed between the cement rotary kiln barrel and the kiln tyre. The beneficial effects of the invention are that the gap measuring device is simple in structure, is convenient to use, is good in effect; the measuring method can be used for the measuring of loosened gaps of any cement rotary kiln tyre.

Description

technical field [0001] The invention relates to a tire gap in hot state of a cement rotary kiln, in particular to a measuring device for a tire gap in a hot state of a cement rotary kiln and a use method thereof. Background technique [0002] At present, due to the different temperatures of the gear wheels and the kiln shell during the operation of the cement rotary kiln, the gaps between the cold state and the hot state are very different, but what is actually needed is the largest upper gap in the hot state during operation, and the cement The gap between the rotary kiln and the kiln can’t be measured in practice; now, the difference between the tire and the kiln shell is generally divided by the π value to obtain the gap between the wheel and the kiln shell. From the point of view of the situation, the discrepancy is relatively large. It is believed that only the ideal situation of pure rolling of the kiln shell on the inner surface of the tire is considered, but in fact ...

[0002] At present, due to the different temperatures of the gear wheels and the kiln shell during the operation of the cement rotary kiln, the gaps between the cold state and the hot state are very different, but what is actually needed is the largest upper gap in the hot state during operation, and the cement The gap between the rotary kiln and the kiln can’t be measured in practice; now, the difference between the tire and the kiln shell is generally divided by the π value to obtain the gap between the wheel and the kiln shell. From the point of view of the situation, the discrepancy is relatively large. It is believed that only the ideal situation of pure rolling of the kiln shell on the inner surface of the tire is considered, but in fact there is more or less sliding phenomenon.
