Description

Technical Field

[0001] This utility model relates to the field of steel structure weld inspection technology, and in particular to a steel structure weld inspection instrument. Background Technology

[0002] A steel structure weld inspection instrument is a specialized device used to detect defects, cracks, and other problems in welded steel structures to ensure weld quality and strength. It utilizes various non-destructive testing techniques and instruments (such as ultrasonic, X-ray, eddy current, magnetic particle, etc.) to inspect and analyze welds to determine whether their structure and performance meet the requirements of standards and specifications.

[0003] Currently, steel structure weld inspection instruments typically consist of inspection equipment, data processing and analysis software, a display, and video recording equipment. However, in practical applications, the inventors have gradually discovered that existing steel structure weld inspection instruments, such as X-ray inspection instruments, are not easy to move, which affects the inspection of steel structure welds. Therefore, we have proposed a steel structure weld inspection instrument. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a steel structure weld inspection instrument to solve the technical problem that current steel structure weld inspection instruments and X-ray inspection instruments are not easy to move, which affects the inspection of steel structure welds.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A steel structure weld inspection instrument includes a protective cover, one side of which has an assembly opening, and the bottom wall of the inner cavity of the protective cover is provided with a relief groove, which is connected to the assembly opening.

[0008] An X-ray detector is detachably installed inside the protective cover, and the X-ray detector is installed inside the protective cover through the assembly opening and the clearance groove;

[0009] A connecting rod is installed on the top of the protective cover. The outer surface of the connecting rod is provided with a mounting base. The connecting rod is driven by a driving device installed on the mounting base, and the connecting rod is slidably installed on the mounting base through the driving device.

[0010] As an improved technical solution, multiple heat dissipation grids are provided on both the left and right walls of the inner cavity of the protective cover, and the multiple heat dissipation grids are arranged at equal intervals along the length of the protective cover.

[0011] As an improved technical solution, the driving device includes a stepper motor, which is mounted on one end of the mounting base. A threaded rod perpendicular to the connecting rod is rotatably mounted inside the mounting base. The output shaft of the stepper motor is connected to one end of the threaded rod. A movable block is also slidably mounted inside the mounting base along the axial direction of the threaded rod, and the movable block is threadedly connected to the threaded rod. The end of the connecting rod away from the protective cover is mounted on the bottom of the movable block.

[0012] As an improved technical solution, the mounting base has a sliding groove inside that corresponds to the moving block, and the sliding groove is adapted to the moving block;

[0013] The bottom wall of the inner cavity of the slide groove is provided with a limiting groove corresponding to the connecting rod, and the connecting rod is slidably installed in the limiting groove through a moving block.

[0014] As an improved technical solution, four connecting plates are fixedly installed on the outer surface of the mounting base. An electric push rod is fixedly installed at the end of the connecting plate away from the mounting base, and a base is fixedly installed at the end of the electric push rod away from the connecting plate.

[0015] As an improved technical solution, the four connecting plates are symmetrically arranged along the length and width central axes of the mounting base;

[0016] The connecting plate has an inverted L-shaped structure with a horizontal connecting part and a vertical connecting part. The horizontal connecting part is installed on the mounting base, and the vertical connecting part is installed on the end of the electric push rod away from the base.

[0017] As an improved technical solution, the top of the base has an integrally formed fixing groove, and the end of the electric push rod away from the connecting plate is installed in the fixing groove.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are:

[0019] 1. This utility model, by starting a stepper motor and an X-ray detector, causes the output shaft of the stepper motor to drive a threaded rod to rotate within the mounting base. The threaded rod drives a moving block to move along the outer surface of the threaded rod and the inner cavity of the sliding groove. The moving block drives a connecting rod to move, which in turn drives a protective cover and the X-ray detector located within the protective cover to move along the length of the weld. Simultaneously, the X-ray detector inspects the weld. The X-ray detector obtains an X-ray transmission image by irradiating the weld area with X-rays. Through image analysis and processing, it detects the presence of welding defects. During this process, the moving block drives the connecting rod to move along the inner cavity of the limiting groove, acting as a limiting guide and ensuring more stable movement of the X-ray detector. This allows for stable movement of the X-ray detector and facilitates the inspection of welds in steel structures.

[0020] 2. This utility model involves placing the device on a steel plate, with the X-ray detector inside the protective cover positioned directly above the weld seam of the steel plate. Then, the electric push rod is activated. The electric push rod moves the connecting plate, which in turn moves the mounting base. The mounting base then moves the protective cover and the X-ray detector inside the protective cover until the X-ray detector is adjusted to a suitable inspection height. During this process, the length of the electric push rod can be changed to adjust the height of the X-ray detector, thus facilitating the inspection of the weld seams of the steel structure.

[0036] Reference Figure 4 The driving device includes a stepper motor 5, which is mounted on one end of the mounting base 4. A threaded rod 6, which is perpendicular to the connecting rod 3, is rotatably mounted inside the mounting base 4. The output shaft of the stepper motor 5 is connected to one end of the threaded rod 6. A moving block 7 is also slidably mounted inside the mounting base 4 along the axial direction of the threaded rod 6, and the moving block 7 is threadedly connected to the threaded rod 6.

[0037] Reference Figure 4 The mounting base 4 has a groove 401 inside that corresponds to the movable block 7, and the groove 401 is adapted to the movable block 7 so that the movable block 7 can move along the inner cavity of the groove 401.

[0038] The bottom wall of the inner cavity of the slide groove 401 is provided with a limiting groove 402 corresponding to the connecting rod 3, and the connecting rod 3 is slidably installed in the limiting groove 402 through the moving block 7. The moving block 7 drives the connecting rod 3 to move along the inner cavity of the limiting groove 402, so as to play a limiting and guiding role, thereby ensuring that the X-ray detector 2 moves more stably.

[0039] Reference Figure 1-4 Four connecting plates 8 are fixedly installed on the outer surface of the mounting base 4.

[0040] Reference Figure 1-3 The four connecting plates 8 are symmetrically arranged along the length and width central axis of the mounting base 4;

[0041] The connecting plate 8 has an inverted L-shaped structure with a horizontal connecting part and a vertical connecting part.

[0043] In actual use, the device is placed on a steel plate, with the X-ray detector 2 located inside the protective cover 1 directly above the weld of the steel plate.

The moving block 7 drives the connecting rod 3 to move, and the connecting rod 3 drives the protective cover 1 and the X-ray detector 2 located within the protective cover 1 to move along the direction of the weld length. At the same time, the X-ray detector 2 inspects the weld. The X-ray detector 2 obtains an X-ray transmission image by irradiating the weld area with X-rays. At the same time, by analyzing and processing the image, it detects whether there are welding defects. During this period, the moving block 7 drives the connecting rod 3 to move along the inner cavity of the limiting groove 402, and plays a limiting and guiding role, while ensuring that the movement of the X-ray detector 2 is more stable. Thus, the X-ray detector 2 can be moved stably, and it is convenient to inspect the welds of the steel structure. This device can not only move the X-ray detector 2 stably, but also facilitate the inspection of the welds of the steel structure.
