Description

Technical Field

[0001] This new inspection tooling specifically relates to an auxiliary tooling for visual inspection of welds. Background Technology

[0002] The nuclear power plant's "Centralized Examination Center for Welder Skills Assessment" has a high demand for examinations and a large number of test pieces. After the welder's examination, all pipe test pieces need to be inspected. The pipe test pieces are large and heavy, requiring either independent handling or assistance from a specialist to rotate them. The inspection process is extremely slow, and there is a high risk of personal injury during the inspection, as well as potential damage to the work surfaces.

[0003] Therefore, an auxiliary tooling for visual inspection of welds is needed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an auxiliary tooling for visual inspection of welds.

[0005] This invention is achieved as follows: an auxiliary tooling for visual inspection of welds, comprising a base, a support assembly on the base, and a bearing on the support assembly, wherein the support assembly has an "L" shaped cross section with the tip of the "L" facing the ground.

[0006] As described above, in an auxiliary tooling for visual inspection of welds, the base is composed of arc-shaped semi-circular steel and square steel, and the shape of the upper surface of the base matches the shape of the lower surface of the support assembly.

[0007] As described above, the auxiliary tooling for visual inspection of welds includes an angle steel support component.

[0008] As described above, an auxiliary tooling for visual inspection of welds includes several bearings mounted on the angle steel, with the bearings located on both arms of the "L" shape.

[0009] The above-described auxiliary tooling for visual inspection of welds includes angle steel, curved semi-circular steel, and square steel welded together.

[0010] As described above, the auxiliary tooling for visual inspection of welds includes square steel components welded together in a triangular shape to make the tooling more stable.

[0011] As described above, a visual inspection auxiliary tooling for welds includes a total of 6 bearings, with 2 on one arm and 4 on the other arm.

[0012] As described above, the auxiliary tooling for visual inspection of welds includes an arm with four bearings, which are divided into two groups of two bearings each, positioned at different heights on the arm. By matching the bearings on the other side of the arm, it enables support for pipes of different diameters.

[0013] The significant effects of this new invention are: (1) Before application, it takes 300 seconds to inspect a pipe specimen. When encountering a larger or heavier pipe specimen, two welders need to be arranged to assist the inspector in rotating the specimen.

[0014] After applying the tube test piece inspection fixture, only one inspector is needed to inspect the tube test pieces, and the inspection of one tube test piece only takes 30 seconds, which greatly improves inspection efficiency, reduces labor intensity, and enhances safety.

[0015] (2) This tooling can be used for various pipe diameters to meet the needs of examination and inspection;

[0016] (3) The tooling is simple to make, easy to use, and has a low production cost. It can be made using existing materials in the on-site warehouse.

[0017] (4) The “Auxiliary tooling for visual inspection of welds” can be extended to other projects, whether nuclear power or non-nuclear power, for the inspection of such pipe test pieces, and has great promotional value. Attached Figure Description

[0019] In the diagram: 1. Angle steel, 2. Bearing, 3. Curved semi-circular steel, 4. Square steel Detailed Implementation

[0020] As attached Figure 1 As shown, an auxiliary tooling for visual inspection of welds consists of angle steel 1, bearing 2, arc-shaped semi-circular steel 3, and square steel 4. Angle steel 1 supports the bottom of the inspection specimen, serving as a "foundation" to provide load-bearing capacity. Square steel 4, composed of seven square steel pieces, provides fixation; the square steel pieces are welded in a triangular shape to make the tooling more stable, firm, and pressure-resistant. Bearing 2, composed of six bearings, is the main tool for rotating the specimen, supporting its rotation, reducing the coefficient of friction during movement, and ensuring its rotational speed and accuracy. Arc-shaped semi-circular steel 3 acts as a link, tightly integrated with angle steel 1 to form a bridge with bearing 2.

[0021] In use, the tube specimen is placed on an angle steel, and the bearing 2 is used to flip the tube specimen to complete the inspection. Applying this fixture to inspect tube specimens improves the inspection speed and efficiency, and effectively prevents mechanical injuries to personnel during the inspection process.
