Embodiment Construction
[0030] The present invention is described in detail below with reference to accompanying drawing and embodiment:
[0031] See figure 1 and figure 2 , the present invention Measuring method of supporting wheel axis and cylinder axis of dynamic rotary kilnYes: establish a Cartesian coordinate system X, Y, Z outside the rotary kiln, parallel to the X direction on one side of the rotary kiln, use a fixed laser collimator 5 to shoot a beam of laser reference line 6 parallel to the axis of the kiln body, the reference line The vertical plane where it is located is Q, open the end cover of each support roller shell, and then proceed as follows:
[0032] 1) see figure 2 , install the two shaft hole centerers 8 on the taper holes of the two dynamic support wheel shaft ends on the same side, and intercept the laser with the receiving screen 7 at the section determined by the three points L, R, and G or at the vicinity of ±10 mm Datum projection point G; see figure 1 At a fix...

The invention relates to a method and a device for measuring riding wheel axis and barrel axis of a dynamic rotary kiln. The method provided by the invention comprises the following steps: building a rectangular coordinate system outside the rotary kiln; installing two shaft hole centralizers on axis taper holes of two dynamic riding wheels arranged at the same side through shaft hole centralizers, a ranging theodolite, a receiving screen, a laser collimator and the like, and directly observing spatial position parameters, namely altitude difference and horizontal range, of axes and coordinate system origins of the two shaft hole centralizers through the ranging theodolite at the same side; moving the two shaft hole centralizers and the ranging theodolite to the other side of the two riding wheels; directly observing the spatial position parameters of the axes of the two riding wheel at the same time; sequentially repeating the above operations on other riding wheels to measure spatial position parameters of all the riding wheels and figure out the deviation value of real axis relative to collimation axis of a kiln barrel; and regulating position of the riding wheels according to the deviation value and straightening the axis of the rotary kiln. According to the invention, the measurement precision for the center of the rotary kiln barrel is equal to or less than 1.5mm so as to avoid errors in the artificial operation and reading. The device provided by the invention is simple and convenient to operate and is easy to popularize.
Description
technical field [0001] The invention relates to a method and an instrument for measuring the axis of a supporting wheel of a rotary kiln, in particular to a method and an instrument for measuring the axis of a supporting wheel and the axis of a cylinder of a dynamic rotary kiln. Background technique [0002] Rotary kiln is an important firing equipment for industries such as cement, nonferrous and ferrous metallurgy, chemical industry, and refractory materials. The kiln is generally supported by more than three sets of supporting wheels for continuous operation. In the long-term operation, due to the uneven wear of the supporting roller and the tire belt, the uneven settlement of the kiln base pier, and the deviation of the position of the supporting roller, the operating axis of the rotary kiln is not in a straight line, causing mechanical failure of the kiln and shortening the service life of the kiln lining. Therefore, it is necessary to frequently measure the position o...
