Problems solved by technology

But the disadvantage is that the measurement procedure is more complicated, the theodolite has many moving points, the on-site measurement takes a long time, the workload is heavy, and it has not completely deviated from the traditional measurement method. It has strict requirements on the rotation speed of the rotary kiln. The lower measurement error is between ±5mm
The procedure for measuring the centerline of the rotary kiln shell in this patent is cumbersome, and multiple calculations are likely to cause system errors, so that the adjustment of the centerline of the rotary kiln shell is inaccurate and cannot reach the ideal state, which in turn affects the normal operation of production

Embodiment Construction

[0060] This embodiment specifically illustrates the method for quickly measuring and judging the centerline of a rotary kiln, including the following steps:

[0061] 1) The measurement of the actual horizontal projection distance A1 between the tire belt and the center line of the support roller, such as figure 1 shown.

[0062] First, set up a theodolite at the erection point 1 of the measuring instrument on the support seat of the supporting wheel set at the cold end of the rotary kiln, and establish a reference line 3 on the side of the rotary kiln with the center mark on the support seat of the supporting wheel 2 at both ends as the reference, It is required that the difference between the baseline 3 and the horizontal distance OB1 and OB2 between the original center marks at both ends when establishing the measurement point should be as small as possible.

[0063] Then, open the small end caps of the shaft heads of all supporting roller supports, find out the central mac...

Abstract

The invention relates to a method for fast measurement and judgment of a central line of equipment like a rotary kiln, which comprises the following steps: firstly measuring the actual horizontal projection distance A1 of the central line of a wheel belt and a support wheel, further calculating the horizontal movement adjustment quantity X of the support wheel and the support half-angle theta of the support wheel after adjustment according to a formula, judging whether the horizontal movement adjustment quantity X of the support wheel can lead the support half-angle theta of the support wheel after the adjustment to be not less than 28.5, and finally determining a group of X values which are in line with the requirements for fast adjustment of the central line of a cylinder body of the rotary kiln. The measurement method has the advantages of simpleness, easy operation, small system error, high adjustment accuracy and fast speed.

Description

technical field [0001] The invention relates to a maintenance method for rotary kiln equipment, in particular to a method for measuring and judging the centerline of a cylinder body of rotary kiln equipment. Background technique [0002] Rotary kiln equipment is widely used in many sectors of national economic production, especially in the building materials industry, and is the core of enterprise production organization and equipment management. During the original installation of the rotary kiln, since the tires, supporting rollers, and cylinder are all made according to the drawings, the error is small. Under the condition that the center line of the foundation is correct, the center height is used as the main dimension of the installation, and the included angle of the supporting rollers is also easy. controlled within a reasonable range. However, after long-term operation, tire belts, support rollers, and cylinder backing plates will be worn to varying degrees, and the...
