Abstract

Rotary drum aggregates are often used in technological lines for continuous production. These complex structures are exposed to stresses and deformations under the influence of temperature and dynamical stress. To determine geometric parameters of such units, in this paper we propose to use a total station. The basic idea of the method is a remote real-time geodetic measurement of the machine parameters in the reflectorless mode. The task posed is solved by simultaneous measuring of the point spatial coordinates on the rotating machine and the timing of the measurement. As a part of work, a mathematical model was developed through which the geometrical parameters of the rotation body were determined and various random and systematic influencing factors are investigated. For the implementation of the proposed technology, the geodetic measuring complex “Vizir 3D” was updated accordingly. This paper shows an example of measurement of a drying unit. The results of vibration diagnostics of the support rollers of the drying drum allow determining the values of the parameters of vibration acceleration on the rollers. The peak factor and the vibration acceleration kurtosis of the support rollers should be less than 6 and 4, respectively.
