[0002] The utility model with publication number CN207440011U discloses an ultrasonic pipeline non-destructive testing device, which belongs to pipeline inspection equipment. It aims to provide an ultrasonic pipeline non-destructive testing device with simple structure and easy operation. Its technical solution is as follows: it includes a support frame, which is an arc-shaped hollow structure with openings at both ends. Telescopic plates are respectively installed at both ends of the support frame.

[0014] In this invention, the first semicircular mold is fixed and released on the pipeline through the cooperation between the first electric telescopic rod and the first clamp. The second semicircular mold is fixed and released on the pipeline through the cooperation between the second electric telescopic rod and the second clamp. The first and second semicircular molds move axially on the pipeline through the cooperation between the third electric telescopic rod and the first and second semicircular molds. Then, the connecting plate is driven to perform circumferential motion by the rotation of the arc-shaped toothed ring, thereby performing all-round flaw detection on the outer wall of the pipeline. It is easy to operate and has a high degree of automation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 The pipeline non-destructive testing equipment includes a first semicircular mold 1, a second semicircular mold 2, and a third semicircular mold 3. The opening directions of the first semicircular mold 1, second semicircular mold 2, and third semicircular mold 3 are all the same. A first electric telescopic rod 4 is installed on each of the two inner sides of the first semicircular mold 1, and a first clamp 5 is installed on the telescopic shaft of each of the two first electric telescopic rods 4. A second electric telescopic rod 6 is installed on each of the two inner sides of the second semicircular mold 2, and a second clamp 7 is installed on the telescopic shaft of each of the two second electric telescopic rods 6. A third electric telescopic rod 8 is installed between the first semicircular mold 1 and the second semicircular mold 2.

A connecting plate 10 is connected to one side of the arc-shaped toothed ring 9. A screw 11 is threaded onto the connecting plate 10. A knob 12 is connected to one end of the screw 11, and an ultrasonic probe 13 is installed on the other end. A motor 14 is installed on the second semi-circular mold 2. A first pulley 15 is connected to the output shaft of the motor 14. A first gear 16 is connected to one end of the first pulley 15. The first gear 16 meshes with the arc-shaped toothed ring 9.

The second gear 19 meshes with the arc-shaped toothed ring 9.

[0023] The motor 14 drives the first pulley 15 to rotate, causing the first gear 16 to rotate. Through the belt 17, the second pulley 18 rotates synchronously in the same direction, driving the second gear 19 to rotate. This causes the arc-shaped toothed ring 9 to perform continuous circular motion on the third semi-circular mold 3, thereby moving the connecting plate 10. Through the screw 11, the distance between the ultrasonic probe 13 and the outer wall of the pipe is adjustable, making pipe flaw detection more convenient and easier to operate.

The third electric telescopic rod 8 works with the first and second semi-circular molds 1 and 2 to move axially on the pipe.

The operation is convenient and highly automated.

The width of the limiting ring 21 is greater than the width of the arc-shaped toothed ring 9. The limiting ring 21 is slidably connected inside the third semi-circular mold 3 to prevent the arc-shaped toothed ring 9 from separating from the third semi-circular mold 3.

[0027] Specifically, in this embodiment, the connecting plate 10 has a threaded hole 22, and the screw 11 is threaded into the threaded hole 22, so that the screw 11 drives the ultrasonic probe 13 to adjust its position and ensures the stability after adjustment.

[0028] Specifically, in this embodiment, a first bracket 23 is provided on the second semi-circular mold 2, and the motor 14 is arranged on the first bracket 23 to provide support for the motor 14.

[0029] Specifically, in this embodiment, the third semicircular mold 3 is provided with two second supports 24, which are symmetrical to each other. The connecting shaft between the first pulley 15 and the first gear 16, and the connecting shaft between the second pulley 18 and the second gear 19 are respectively rotatably connected in the second supports 24 at the corresponding positions, providing fulcrum for the rotation of the first gear 16 and the second gear 19.
