Abstract
Description
Technical Field
[0001] The invention relates to the technical field of traction wheel detection, and in particular to a method and a device for detecting uneven wear of a traction wheel groove. Background Art
[0002] The traction sheave is a wheel-shaped component installed on the traction machine and driven to rotate by the motor through the reducer. Its main function is to pull the car and counterweight device up and down in the elevator shaft through the friction between the wire rope and the wheel rim. It is usually round and has a special groove design on the rim to accommodate and fix the wire rope. The shape and size of the groove are precisely designed to ensure that the wire rope can be stably embedded in it and will not slip during operation. It is generally used in elevator equipment. According to the current national standard "Technical Conditions for the Scrap of Main Elevator Components" (GB / T31821-2015), Article 4.2.4, "abnormal wear of the rope groove" is regarded as one of the technical conditions for the scrapping of the traction sheave, and uneven wear of the wheel groove is also abnormal wear.
[0003] However, the detection methods for uneven wear of the traction wheel groove are generally visual inspection and scanning. The visual inspection generally uses a measuring ruler for detection. By using various types of measuring rulers to measure and read the worn parts, and repeatedly testing and comparing with the original normal data, the range of wear degree can be determined. The advantage is that the detection is more intuitive and the wear condition can be directly seen. The disadvantage is that the process is very complicated and troublesome, and it is often necessary to judge based on the visual inspection and experience of the inspectors, which leads to insufficient accuracy. For some small uneven wear, it is impossible to directly find the worn parts by naked eye observation alone, and it takes a long time to locate them by naked eye, resulting in low detection efficiency. The scanning method generally constructs a three-dimensional model through point cloud data obtained by laser scanning, but the special concave shape of the inner wall of the groove causes the light source to be blocked by the side wall during exposure, making it difficult to meet the shooting requirements. At the same time, the annular structure of the wheel groove will also lead to a lack of feature points in the scan, and the dust and oil attached to the inner wall of the wheel groove will affect the accuracy of the modeling after scanning.

At the same time, start the laser distance sensor to rotate around the outer side of the traction wheel to be measured.

[0021] S5, final inspection stage, when the detection module reaches the mark, the camera and scanner are started, the irregular wear of the wheel groove is photographed and scanned, the digital image is subjected to image distortion correction, binarization processing, image segmentation, and the contour curve of the wheel groove surface scanned by the laser line in the photo is extracted.

[0022] (III) Beneficial effects
[0023] The present invention provides a method and device for detecting uneven wear of a traction sheave groove. It has the following beneficial effects:
[0024] 1. The traction sheave groove uneven wear detection device is provided with a laser distance sensor, which senses a slight distance change according to the distance from the laser to the sheave groove. When the length of the laser rotating circumferentially around the traction sheave changes, the position of the recessed part can be quickly located, thereby avoiding the situation that the human eye cannot observe due to vision problems during observation. The marking mechanism marks the edge of the traction sheave, thereby more intuitively locating the position of the uneven wear, reducing the time for the human eye to find the specific position of the uneven wear, and greatly improving work efficiency.
[0025] 2. The traction wheel groove uneven wear detection device cleans the wheel groove of the traction wheel through the cleaning module to eliminate the misdetection caused by dust and oil in the wheel groove, reduce errors, and improve detection accuracy. After the dust and oil in the traction wheel groove are cleaned, when the auxiliary module applies the developer in the wheel groove, the adhesion effect of the developer can be greatly improved, the diffuse reflection of the inner wall of the wheel groove is increased, and a large number of feature points are added to enable the scanner to receive more reflected light, thereby greatly improving the accuracy of scanning detection.

8. The detection method proposed by the traction sheave groove uneven wear detection device according to any one of claims 1 to 7 is characterized in that The following steps are involved: S1, installation stage, insert the traction wheel (41) to be tested along the positioning column (9) to the baffle (39), limit the rotation thereof by the limiting strip (40), and then insert the fixing mechanism. During the insertion process, rotate the rotating drum (45), so that the inner wall of the rotating drum (45) is threadedly connected to the positioning column (9) and the retaining ring (42) is tightly pressed against the front surface of the traction wheel (41) to be tested, thereby achieving the purpose of adapting to the fixed installation of the traction wheel (41) to be tested with different thicknesses; S2, the initial inspection stage, the first motor (4) is started to drive the gear (6) on the first rotating shaft (5) to rotate, so that the rotating frame (1) starts to rotate under the action of the gear (6) and the latch (3), and is relatively stable under the action of the three pairs of limit columns (11) during the rotation. At the same time, the laser distance sensor (35) is started to rotate around the outer side of the traction wheel (41) to be measured. When the laser emitted by the laser distance sensor (35) measures that the distance from the wheel groove of the traction wheel (41) to the laser distance sensor (35) changes, it indicates that there is an irregular depression at that location. At this time, the rotation is stopped and the third electric telescopic rod (36) is started to extend it, and a mark is left on the corresponding position of the front surface of the traction wheel (41) to be measured by a marking pen (38), so as to quickly locate the traction wheel; S3, starting the driving mechanism for the second time, so that the laser distance sensor (35) rotates around the traction wheel (41) to be tested again and detects, and simultaneously starting the No. 1 electric telescopic rod (13) and the No. 2 motor (15), and pressing the wiping cotton (21) on the roller (20) into the wheel groove of the traction wheel (41) to be tested through the No. 1 electric telescopic rod (13), and then driving the roller (20) on the second rotating shaft (16) to rotate through the No. 2 motor (15), so as to wipe the wheel groove, eliminate the situation that the dust and oil on the wheel groove in the initial inspection stage cause the misdetection, and improve the detection accuracy and precision, and under the transmission action of the No. 1 wheel (17), the No. 2 wheel (18) and the belt (19), drive the wind wheel (23) on the third rotating shaft (22) to rotate rapidly, and suck the dust brought out by the wiping cotton (21) during the rotation process into the filter box (24) through the air inlet (25) for filtration and collection; S4, re-inspection stage, the driving mechanism is started for the third time, so that the laser distance sensor (35) re-inspects around the wheel groove of the traction wheel (41) to be tested. If there is no distance change, it can be determined that the data in the initial inspection stage is a mismeasurement. If there is still a distance change in the initial inspection stage, it means that there is indeed an irregular depression at that location. At this time, the second electric telescopic rod (28) is started to push the rolling wheel (31) into the wheel groove of the traction wheel (41) to be tested. The rolling wheel (31) rolls with the wheel groove, and the developer in the reagent box (29) is rolled into the wheel groove; S5, final inspection stage, when the inspection module reaches the mark, the camera (33) and the scanner (34) are started, the irregular wear of the wheel groove is photographed and scanned, the digital image is subjected to image distortion correction, binarization processing, image segmentation, and the contour curve of the wheel groove surface scanned by the laser line in the photo is extracted, and the obtained curve is fitted and analyzed with the contour curve of the normal wheel groove surface without wear, so as to judge the degree of wear.
