Description

Technical Field

[0001] This utility model relates to the field of overhead conductor aluminum pole production technology, and specifically to a testing device for overhead conductor aluminum pole production. Background Technology

[0002] Overhead conductors are a core component of power transmission lines, and their quality directly affects the reliability and safety of the power grid. Aluminum poles, as the core raw material for producing overhead conductors, have a decisive impact on the conductivity and mechanical strength of the final conductors. Currently, aluminum poles for overhead conductors are mainly produced using a continuous casting and rolling process. This process involves continuously casting liquid metal into infinitely long ingots, which are then continuously fed into a rolling mill to be directly rolled into poles. This process has significant advantages such as high production efficiency and high material utilization. However, under the high-temperature and high-speed production conditions of continuous casting and rolling, aluminum poles are highly susceptible to various defects such as scratches, cracks, porosity, and inclusions. These defects pose a serious threat to the performance and operational safety of overhead conductors.

[0003] Existing aluminum rod surface defect detection devices generally rely on single-view image acquisition and flaw detection, making it difficult to achieve continuous online detection of the aluminum rod's entire circumference (360°). Furthermore, the detection rate for minor defects such as scratches and microcracks is also low. Therefore, these problems urgently need to be addressed. Utility Model Content

The large-diameter end of the collection hood 10 is arranged facing forward and does not affect the transmission action of the conveying mechanism I1 or the conveying mechanism II14. The small-diameter end of the collection hood 10 extends vertically to the rear outer surface of the portal frame 3 and is sealed to the dust removal assembly 11 installed at the corresponding position on the rear outer surface of the portal frame 3. The dust removal assembly 11 collects the residual debris that has been cleaned up through the collection hood 10.

[0027] The left side of the cylindrical body 15 extends vertically out of the left side of the frame 17, and a driven gear 18 is coaxially and fixedly attached to its left side. A through hole is also coaxially and vertically opened on the left side of the driven gear 18.

Under the drive of the motor 20, the cylinder 15 is driven to rotate around its own axis through the meshing of the main gear 19 and the driven gear 18.

[0028] The distance between conveying mechanism II14 and conveying mechanism III26 must ensure that the aluminum rod 2 can be smoothly transferred from conveying mechanism II14 to conveying mechanism III26, and the rotation of cylinder 15 must not interfere with the transmission actions of conveying mechanism II14 and conveying mechanism III26 respectively. Through the cooperation of conveying mechanism II14 and conveying mechanism III26, the aluminum rod 2 is horizontally passed through cylinder 15 for all-round detection.

[0029] like Figure 1As shown, the vertical thickness of the mounting plate 22 must ensure that the ultrasonic flaw detector 24 rotates synchronously with the cylinder 15, so as not to interfere with the movement of the aluminum rod 2 from the conveying mechanism II 14 to the conveying mechanism III 26, and to ensure that the ultrasonic flaw detector 24 can detect the aluminum rod 2 during transmission; a mounting base 21 is also provided on the lower surface of the frame 17, and the frame 17 is fixedly installed on the ground by the mounting base 21; the mounting base 21 does not exceed the vertical coverage of the frame 17, and the height of the mounting base 21 must ensure that the center line of the cylinder 15 and the center line of the aluminum rod 2 during transmission are horizontally aligned.

[0031] The working principle of this utility model: Aluminum rod 2 is transferred from conveyor mechanism I1 to conveyor mechanism II14. During the pretreatment process, the fan 6 continuously blows air onto the surface of aluminum rod 2 through the main air duct 7, branch air duct 8 and air outlet 9, thereby cooling the aluminum rod 2 and removing residual impurities from its surface. The dust removal component 11 collects the removed residual impurities through the collection cover 10. Then, aluminum rod 2 is transferred from conveyor mechanism II14 to conveyor mechanism III26. During the process of passing through the cylinder 15 coaxially, infrared sensor 23 receives the signal of the arrival of aluminum rod 2. Then, through the cooperation of motor 20, main gear 19, driven gear 18 and bearing 16, the cylinder 15 rotates around the axis of aluminum rod 2 within the frame 17. At this time, the surface defects of aluminum rod 2 can be detected by the cooperation of ultrasonic flaw detector 24 and industrial camera 25, thereby realizing online continuous detection of aluminum rod 2 in all 360° circumference.

[0032] The beneficial effects of this utility model are: (1) By using the motor 20, main gear 19, driven gear 18 and bearing 16 together, the cylinder 15 can rotate around the aluminum rod 2 in the frame 17, thereby realizing online continuous detection of the aluminum rod 2 in the full circumference 360°. This process saves time and effort and improves detection efficiency and effect. (2) This utility model reduces blind spots in detection and improves the detection rate of minor defects such as minor scratches and microcracks by using two rows of industrial cameras 25 arranged in an alternating manner; (3) By combining the fan 6, the main air duct 7, the branch air duct 8 and the air outlet 9, the aluminum rod 2 can be cooled and dusted before testing, thus laying a good foundation for subsequent surface defect detection operations and improving the detection accuracy.
