Description

Technical Field

[0001] The utility model belongs to the technical field of weld quality detection, in particular to a water pipe weld quality detection device. Background Art

[0002] Welding, also known as fusion or melting, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. During the installation of electromechanical equipment in hydropower stations, two sections of water pipes need to be welded. After welding the water pipes, welds will be produced and their sealing needs to be ensured. After welding is completed, the welds need to be inspected for welding quality.

[0003] Most existing detection methods use ultrasonic detectors to inspect welds. They can accurately detect the exact location and size of internal defects in welds. However, since water pipes are round pipe parts, workers are required to hold ultrasonic probes to inspect the weld quality around the weld during weld inspection. The ultrasonic probe needs to be rotated 360 degrees along the water pipe, which is cumbersome to operate, and the detection device is not convenient to be placed on the outside of the water pipe.

[0004] Therefore, a water pipe weld quality detection device is proposed. Utility Model Content

[0022] The present invention provides a device for detecting the quality of water pipe welds. Figure 1-4 As shown, it includes a first notch ring 1 and a second notch ring 2, the first notch ring 1 is located on one side of the second notch ring 2, and a slide groove 3 is provided on one side outer wall of the first notch ring 1, and a slider 4 is provided on one side of the outer wall of the second notch ring 2 near the slide groove 3, and the slider 4 and the slide groove 3 are slidably connected, and a tooth groove 5 is provided on the outer wall of the second notch ring 2 adjacent to the slider 4, and a first ultrasonic detection head 6 and a second ultrasonic detection head 7 are fixedly connected to the inner wall of one side of the second notch ring 2 by bolts, the first ultrasonic detection head 6 is located on one side of the second ultrasonic detection head 7, a fixing seat 8 is integrally formed on the outer wall of one side of the first notch ring 1 adjacent to the slide groove 3, and a fixing seat 8 is integrally formed on one side outer wall of the fixing seat 8, and the outer wall of one side of the fixing seat 8 is fixed by bolts. A three-phase asynchronous motor 9 is fixedly connected, and the three-phase asynchronous motor 9 is fixedly connected to a gear 10 through an output end on one side thereof. The gear teeth on the gear 10 are meshed with the tooth grooves 5. A handle 11 is fixedly connected to the outer wall of one side of the fixed seat 8 by bolts. Raised particles are provided on the outer wall of one side of the handle 11.

A water pipe 15 is passed through the inner side of the first notch ring 1 and the second notch ring 2, and a weld 16 is provided on the outer wall of one side of the water pipe 15.

[0023] It should be noted that, since the existing water pipe weld inspection requires workers to hold an ultrasonic probe to inspect the welding quality around the weld, the ultrasonic probe needs to be rotated 360 degrees along the water pipe, which is cumbersome to operate and the detection device is not convenient to be put on the outside of the water pipe. In this embodiment, the gap setting of the first notch ring 1 and the second notch ring 2 facilitates the detection device to be conveniently put on the outside of the water pipe of the electromechanical equipment of the hydropower station, and utilizes the rotation of the second notch ring 2 on the first notch ring 1 to realize the first ultrasonic detection head 6 and the second ultrasonic detection head 7 to perform axial 360-degree ultrasonic detection along the weld 16, thereby realizing all-round detection of the weld 16, facilitating detection while ensuring detection efficiency.

[0024] Specifically, in this embodiment, this solution mainly includes a first notch ring 1 and a second notch ring 2.

Press the forward and reverse buttons 12, and the output end of the three-phase asynchronous motor 9 rotates forward.

Through the engagement of the gear 10 with the tooth groove 5 on the second notch ring 2, and through the sliding of the slider 4 in the slide groove 3, the second notch ring 2 is circularly rotated on the first notch ring 1. The first ultrasonic detection head 6 and the second ultrasonic detection head 7 on the second notch ring 2 move in a circular motion synchronously. After the second notch ring 2 rotates 90 degrees in the forward direction, the first ultrasonic detection head 6 and the second ultrasonic detection head 7 perform ultrasonic detection on an area 180 degrees in the axial direction outside the weld 16 on the water pipe 15. Then, the forward and reverse button 12 is pressed again, the output end of the three-phase asynchronous motor 9 rotates in the reverse direction, the second notch ring 2 rotates 180 degrees in the reverse direction, and the first ultrasonic detection head 6 and the second ultrasonic detection head 7 perform ultrasonic detection on another area 180 degrees in the axial direction outside the weld 16 on the water pipe 15, thereby realizing all-round detection of the weld 16.

[0025] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the width of the gaps on the first gap ring 1 and the second gap ring 2 is greater than the outer diameter of the water pipe 15 .

[0027] In a further preferred embodiment of the present invention, Figure 4 As shown, the cross sections of the sliding groove 3 and the sliding block 4 are both T-shaped structures.
