Abstract

The invention discloses a method for measuring horizontal and vertical skew of a riding wheel shaft of a rotary cement kiln. The detection method comprises horizontal measurement and vertical skew measurement. Horizontal measurement comprises the following steps: A, arranging four targets A1, A2, B1 and B2 on the two sides of a kiln head and the two sides of a kiln tail correspondingly to form straight lines A1-A2 and straight lines B1-B2, installing N targets P1, P2 to Pn on the kiln pier concrete foundation of each gear of the rotary kiln, setting the height of Pn to be zero B, and measuringthe wheel belt distance Xn-X1 between the kiln head and the kiln tail; measuring the average horizontal distance D between the straight lines A1-A2 and the straight lines B1-B2 and the horizontal distances di and di' between the rim of the wheel belt and the straight lines A1-A2 and between the rim of the wheel belt and the straight lines B1-B2; C, calculating the diameter 2R of the rotary kiln and the position yi of the rotating shaft; and D, calculating to obtain a riding wheel linear deviation value epsilon. The method for measuring horizontal and vertical skew of a riding wheel shaft of arotary cement kiln can provide an accurate basis for adjustment of the rotary cement kiln riding wheel.

Description

Technical field [0001] The invention relates to the measurement of a supporting roller shaft of a cement rotary kiln, and in particular to a method for measuring the horizontal and vertical skewness of the supporting roller shaft of a cement rotary kiln. Background technique [0002] As the number of years of operation of the cement rotary kiln increases, the centerline is not straight due to the settlement of the concrete foundation, uneven wear of the supporting roller belt, and improper adjustment of the supporting roller. The non-straight center line will increase the resistance of the rotary kiln and increase the power consumption; in addition, the uneven force caused by the swing of the rotary kiln will aggravate the wear of the external mechanical parts of the rotary kiln and damage the refractory materials inside the rotary kiln, reducing the service life of the parts ; In severe cases, it will cause kiln shutdown failures such as cracking of the cylinder, falling refract...
