Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-5 As shown, an ultrasonic flaw detection device for weld seams of steel lighting poles includes a main body 1. A conveying adjustment assembly 2 is provided on one side of the main body 1. The conveying adjustment assembly 2 includes two conveying components 3 and an adjustment component 4. The conveying component 3 includes a fixed frame 21. A stepper motor 22 is fixedly installed on one side of the fixed frame 21. A drive shaft 23 is fixedly installed at the output end of the stepper motor 22. A first sprocket 24 is passed through and fixedly installed on the drive shaft 23. Chains 27 are meshed around the outer periphery of the two first sprockets 24. A second sprocket 25 is meshed on the other side of the two chains 27. The two ends of the second sprocket 25 are movably installed on the fixed frame 21. A chain guide rail 26 is fixedly installed in the inner cavity of the fixed frame 21. The chain guide rail 26 is slidably installed on the inner side of the chain 27. Several conveying feet 28 are fixedly installed on the outer surface of the chain 27.

[0025] During operation, the stepper motor 22 drives the transmission shaft 23 at the output end to rotate, causing the two first sprockets 24 to rotate accordingly. The chain 27 is limited by the first sprocket 24 and the second sprocket 25. At this time, the chain 27 will rotate with the rotation of the first sprocket 24, thereby driving the conveying foot 28 to move and smoothly convey the steel lighting pole.

[0026] Furthermore, the main body 1 includes a detection platform 11, an ultrasonic flaw detection device 12 is fixedly installed on the top of the detection platform 11, a drop trough 13 is opened on the top of the detection platform 11, and a collection hopper 14 is placed on one side of the bottom of the detection platform 11.

[0027] During operation, the steel lighting poles being transported undergo ultrasonic testing using the ultrasonic flaw detection device 12 to detect flaws in the welds of the steel lighting poles. After the testing is completed, the steel lighting poles fall through the drop trough 13 and are collected by the collection bucket 14, thus completing the collection work after testing.

[0028] Furthermore, the adjusting component 4 includes a base 31, a mounting bracket 32 ​​is fixedly mounted on the top of the base 31, a servo motor 33 with a self-locking function is fixedly mounted on the top of the mounting bracket 32, and a ball screw 34 is fixedly mounted on the output end of the servo motor 33.

[0029] During operation, the base 31 supports the bottom of the mounting frame 32, ensuring the stability of the conveying and adjusting assembly 2 during operation, so that the conveying and adjusting of the steel lighting pole can be carried out continuously and reliably.

[0030] Furthermore, the adjusting component 4 also includes a ball nut 35, which is threaded through and connected to a ball screw 34, and a fixing bracket 21 is fixedly installed on one side of the ball nut 35.

[0031] During operation, when the servo motor 33 is working, the ball screw 34 at the output end rotates. The rotational motion of the ball screw 34 is converted into the linear motion of the ball nut 35 through the threaded engagement between the ball screw 34 and the ball nut 35. This threaded engagement between the ball screw 34 and the ball nut 35 drives the fixed frame 21 on one side to move up and down.

[0032] Furthermore, a fixed bearing 36 is movably mounted on the bottom of the ball screw 34, a support block 29 is fixedly mounted on the bottom of the fixed bearing 36, a base 31 is fixedly mounted on the bottom of the support block 29, and another fixed bracket 21 is fixedly mounted on one side of the support block 29.

[0033] During operation, the bottom of the fixed bearing 36 is fixed by the support block 29, which is beneficial to the stability of the ball screw 34 during rotation.

[0034] Furthermore, the adjusting component 4 also includes two limiting rods 38, both of which are through and slidably mounted with limiting sliders 37, and a fixing bracket 21 is fixedly mounted on one side of the two limiting sliders 37.

[0035] During operation, the fixed frame 21 is raised and lowered by the ball nut 35, which can flexibly control the gap between the two conveying adjustment components 2, thereby adjusting the movement for steel lighting poles of different specifications, so that the gap between the two conveying adjustment components 2 matches the diameter of the steel lighting pole. With the cooperation of the limit slider 37 and the limit rod 38, the stability of the fixed frame 21 during movement is effectively guaranteed, and deviation is avoided.

[0036] Furthermore, both limit rods 38 are connected and fixedly installed with fixing blocks 39, and another fixing bracket 21 is fixedly installed on one side of the two fixing blocks 39;

[0037] During operation, the support block 29 and the fixing block 39 provide multi-point support for the fixing frame 21, which enhances the load-bearing capacity of the fixing frame 21 and ensures that the conveying adjustment component 2 can withstand sufficient weight when conveying the steel lighting pole, thereby improving the reliability of the device.

[0038] Working principle: First, according to the specifications of the steel lighting pole to be inspected, the servo motor 33 is started. The servo motor 33 drives the ball screw 34 to rotate, and the ball nut 35 drives the fixed frame 21 to rise and fall along the limit rod 38. The distance between the two conveying parts 3 is adjusted to match the diameter of the steel lighting pole. Then, the steel lighting pole is placed on the conveying foot 28, and the stepper motor 22 is started. The stepper motor 22 drives the first sprocket 24 to rotate through the transmission shaft 23. The chain 27 slides on the chain guide rail 26, and the conveying foot 28 pushes the steel lighting pole to move towards the inspection platform 11. When the steel lighting pole moves to the inspection platform 11, the ultrasonic flaw detection device 12 performs ultrasonic flaw detection on its weld. After the inspection is completed, the steel lighting pole falls into the collection hopper 14 through the drop trough 13.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
