Description

Technical Field

[0001] This invention relates to the field of cement rotary kilns, and in particular to a method for measuring the wear of the support rollers in cement rotary kilns. Background Technology

[0002] Cement rotary kiln support rollers experience wear during long-term operation, leading to poor contact between rollers. Since the degree of wear is unknown during operation, inspection can only be conducted when the kiln is shut down. However, the wear rate differs between hot and cold conditions. Therefore, online detection of support roller wear is an urgent problem. Current methods involve a person holding a ruler close to the edge of the support roller and using a total station to read the reading. This method is prone to error, requires the person to remain stationary, and involves a safety risk due to the close proximity to the support roller. Summary of the Invention

[0003] The purpose of this invention is to provide a method for measuring the wear of the support rollers in a cement rotary kiln, thereby solving the problems of wear on the support rollers during long-term operation, which leads to installation errors and safety issues.

[0004] The technical solution adopted by this invention to solve its technical problem is: a method for measuring the wear degree of the support rollers of a cement rotary kiln, comprising the following steps:

[0005] S1 establishes two parallel baselines on both sides of the rotary kiln;

[0006] S2 marks each roller seat;

[0007] S3 measures the distance from the center of the support roller to the mark and the distance from the mark to the baseline;

[0008] S4 measures the distance from the edge of the support roller to the baseline;

[0009] S5 calculates the actual radius of the support roller.

[0010] In step S1: two parallel reference lines are established on both sides of the rotary kiln; specifically, this includes: S11) establishing two parallel reference lines near the center position of the outside of each support roller of the rotary kiln.

[0011] In step S2: marking is made on each roller seat; specifically including:

[0012] S21) Open the end caps on both sides of the roller shaft and make a mark at the position directly above the center of the shaft at both ends;

[0013] S22) Place the triangular magnet, iron rod, and perforated measuring tape as close to the axis as possible.

[0014] S23) Observe the changes in the readings of the perforated measuring tape on the marks, and read the maximum value a1 and the minimum value a2 at the two end marks respectively; the distances from the two end marks to the axis are a = (a1 + a2) / 2.

[0015] In step S3: measuring the distance from the center of the support roller to the marker point and the distance from the marker point to the baseline; specifically including:

[0016] S31. Set up the total station on the baseline.

[0017] S32. Use a total station to measure the distance b from the marked point to the baseline;

[0018] In step S4, measuring the distance from the edge of the support roller to the baseline specifically includes:

[0019] S41) Set up the tripod;

[0020] S42) Connect the displacement sensor to the pipe, place it on a tripod using a triangular base, and adjust the level of the displacement sensor by adjusting the triangular base; use a total station to measure the distance c from the edge of the sensor to the baseline.

[0021] S43) Export the receiver data and use software to calculate the distance d between the sensor and the edge of the roller.

[0022] In step S5, the actual radius of the support roller is calculated; the support roller radius r = a + b - (c + d).

[0023] The beneficial effects of this invention are: It effectively reduces human error and eliminates safety hazards associated with people standing near rotating or high-temperature objects. It utilizes a displacement sensor connected to a ruler, and its triangular base allows for adjustment on a tripod. Furthermore, the displacement sensor can measure the distance between the object and the sensor without physical contact. This reduces human error and lowers safety risks for workers.
