Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering quality detection, and more specifically, to a non-destructive detection instrument for construction engineering quality. Background Art

[0002] Although some progress has been made in the current non-destructive testing technology for construction project quality, there are still some significant problems and challenges. These problems not only affect the efficiency and accuracy of testing, but also increase the workload of operators.

[0003] First of all, the traditional inspection method mainly relies on manual handheld spraying of magnetic powder to detect whether there are cracks and gaps on the surface of engineering parts. Although this method is intuitive, it has many defects and the operation process is cumbersome. The operator needs to manually control the range and intensity of the spraying, which is not only time-consuming and labor-intensive, but also easily leads to inconsistent inspection results. Due to the limitations of manual operation, it is difficult to ensure uniform coverage of large-area engineering parts, and some key areas may be missed. In addition, long-term handheld operation will also bring physical burden to the inspectors, affecting work efficiency and accuracy. This method is particularly inadequate when facing large or complex-shaped engineering parts, and cannot meet the growing quality inspection needs of modern construction projects.

[0004] Secondly, in order to improve the traditional manual spraying method, some technologies have tried to use a device with multiple nozzles to realize the magnetic powder spraying function. Although this method has improved efficiency to a certain extent, it still has obvious limitations. In most cases, these nozzles are installed in a fixed structure, which lacks flexibility and adaptability. When faced with large or irregularly shaped engineering parts, the fixed nozzles cannot fully cover all surfaces that need to be inspected. This requires operators to frequently manually adjust the position of the engineering parts or repeatedly move the entire inspection device, which not only increases the complexity of the operation, but also may lead to discontinuity and inconsistency in the inspection results. In addition, fixed nozzles are difficult to adapt to engineering parts of different sizes and shapes, limiting the versatility and practicality of the equipment. This design deficiency makes the inspection process still time-consuming and labor-intensive, and it is difficult to meet the needs of large-scale and high-efficiency inspection.

[0005] In addition, the existing technology also has obvious deficiencies in the post-treatment of magnetic powder spraying. When the magnetic powder is sprayed, there is usually a lack of an effective collection and treatment mechanism, which brings a series of problems: first, the uncollected magnetic powder will cause material waste and increase inspection costs. Second, the scattered magnetic powder may pollute the working environment and affect subsequent inspection work or other construction activities. More importantly, if these magnetic powders contain special ingredients or chemicals, untreated scattering may cause potential harm to the environment. In addition, the lack of an effective recycling system also means that the used magnetic powder cannot be reused or recycled, which does not meet the increasingly important environmental protection and sustainable development requirements in modern engineering.

[0017] (3) Beneficial effects

[0018] Compared with the existing technology, the present invention provides a non-destructive testing instrument for construction engineering quality, which has the following beneficial effects:

[0019] 1. The innovative design of the spraying device cleverly solves the problem of cumbersome, time-consuming and labor-intensive manual handheld spraying of magnetic powder in the existing technology. It consists of components such as a nozzle, a connecting frame, a main pipe and a branch pipe. This design realizes automated spraying and greatly improves work efficiency. The magnetic powder in the storage box is transported to the main pipe through a delivery pump and then distributed to each branch pipe and nozzle, achieving uniform and efficient spraying. In addition, the setting of the lampshade and fluorescent light board enables inspection even in insufficient light. Especially when using fluorescent magnetic powder, defects on the surface of the engineering part can be observed more clearly. This design not only improves the efficiency and accuracy of inspection, but also reduces the labor intensity of the operator.

[0020] 2. The design of the movable device cleverly solves the problem of incomplete detection caused by the fixed installation of the nozzle in the existing technology. It includes components such as a rotating shaft, a mounting frame, a gear, a double rack, a central shaft, a single rack, a connecting rod, a rotating frame, an adapter slot, an adapter frame, a matching frame and a matching slot. It is driven by a motor, and the rotating frame is driven to rotate after being decelerated by a reducer, and then through a series of precise mechanical transmissions, the reciprocating rotation of the nozzle is finally realized. This design enables the nozzle to reciprocate within a certain angle range, greatly expanding the spraying range, and comprehensive detection can be achieved without manual adjustment of the position of the engineering parts. The design of the slide rail and the slide slot further increases the stability and accuracy of the movement. This complex and precise mechanical structure not only improves the comprehensiveness and efficiency of the detection, but also reduces the need for manual operation and reduces operating errors.

[0021] 3. The design of the recovery device cleverly solves the problem of the inability to reasonably collect and process magnetic powder in the existing technology. It consists of a placement bin, a return pipe and a storage box. The placement bin is installed on the inner side of the fixed frame to receive excess magnetic powder sprayed out and magnetic powder flowing from the surface of the engineering part. One end of the return pipe is connected to the placement bin, and the other end extends into the storage box, realizing the automatic recovery of magnetic powder. The input end of the delivery pump is connected to the bottom of the storage box through the delivery pipe, ensuring the reuse of the recovered magnetic powder. This closed-loop design not only greatly reduces material waste and reduces testing costs, but also avoids the pollution of the environment by magnetic powder. At the same time, this recovery system also makes it possible to reuse magnetic powder and improve resource utilization efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

When the light is dim, the magnetic powder and the white contrast enhancer in the storage box 30 can be replaced with fluorescent magnetic powder. Then, after spraying, the fluorescent lamp board 22 installed in the lampshade 21 is turned on, and the reflectivity of the fluorescent magnetic powder can be used to observe whether there are cracks on the surface of the engineering part. The discontinuities or defects on the surface of the engineering part will appear in a bright yellow-green color.
