Description

Technical Field

[0001] The utility model relates to the field of magnetic particle flaw detection, in particular to a magnetic particle flaw detection device which can detect independently on an I-beam frame. Background Art

[0002] I-beam is a common structural steel material, which is often used in engineering. In order to inspect the quality of I-beam, magnetic particle inspection can be used. Magnetic particle inspection is a commonly used non-destructive testing method, which is used to detect defects on the surface or near the surface of materials, such as cracks, inclusions, etc.

[0003] When performing magnetic particle inspection on the upper end surface of an I-beam frame, the existing traveling rollers are fixed. When moving on the surface of the I-beam, the distance between the two sets of traveling rollers cannot be adjusted according to the thickness of the I-beam, and the use environment is relatively limited. Utility Model Content

[0007] As a further solution of the utility model, stabilizing frames are fixedly installed on both sides of the middle part of the lower end surface of the chassis, and supporting rollers are rotatably installed inside the stabilizing frames.

[0008] As a further solution of the utility model, a cleaning structure is provided on one side of the chassis, and the cleaning structure includes a bracket, and an adjusting screw is installed inside the bracket, and a stabilizing plate is rotatably installed at the lower end of the adjusting screw, and a cleaning brush is provided at the lower end of the stabilizing plate.

[0009] As a further solution of the utility model, a slide groove is provided at the front end of the stabilizing plate, and the cleaning brush is located inside the slide groove.

[0011] As a further solution of the utility model, an anti-slip pad is installed on the inner wall of one side of the placement rack close to the bracket.

[0012] As a further solution of the utility model, a telescopic rod is installed on the inner wall of the upper end of the bracket, and the lower end of the telescopic rod is fixedly connected to the upper end of the stabilizing plate.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a magnetic particle flaw detection device that can be independently detected on an I-beam frame includes a chassis 1, and a driving motor 2 is installed at the front and rear ends of the lower end of the chassis 1, and a traveling roller 3 is installed at the lower output end of the driving motor 2. A placement rack 4 is installed on one side of the chassis 1, and a magnetic particle flaw detector 5 is installed on the upper end of the placement rack 4. An adjustment structure 6 is arranged inside the chassis 1, and the adjustment structure 6 includes a bidirectional screw rod 7, and sliders 8 are installed at the front and rear ends of the outer wall of the bidirectional screw rod 7, and the lower end of the slider 8 is fixedly connected to a connecting rod 10, and a connecting plate 9 is installed at the upper end of the driving motor 2, and the connecting plate 9 is fixedly connected to the connecting rod 10.

[0023] In this embodiment, stabilizing frames 11 are fixedly installed on both sides of the middle part of the lower end surface of the chassis 1, and supporting rollers are rotatably installed inside the stabilizing frames 11.

[0024] The stabilizing frame 11 is used to install the support rollers, which ensure that the chassis 1 is in stable contact with the upper end of the I-beam.

[0025] In this embodiment, a cleaning structure 12 is provided on one side of the chassis 1, and the cleaning structure 12 includes a bracket 13, and an adjusting screw 14 is installed inside the bracket 13, and a stabilizing plate 15 is rotatably installed at the lower end of the adjusting screw 14, and a cleaning brush 16 is provided at the lower end of the stabilizing plate 15.

[0026] The bracket 13 is used to set the adjusting screw rod 14, and the adjusting screw rod 14 is used to adjust the contact between the cleaning brush 16 and the upper end of the I-shaped piece.

[0027] In this embodiment, a slide groove 17 is formed at the front end of the stabilizing plate 15 , and the cleaning brush 16 is located inside the slide groove 17 .

[0028] The arrangement of the slide groove 17 enables quick removal and installation of the cleaning brush 16, making it convenient for later replacement and cleaning.

[0029] In this embodiment, a mounting screw 18 is installed with an internal thread on one side of the placement rack 4, and one end of the mounting screw 18 is rotatably connected to a C-shaped plate 19, and a rectangular reserved groove 20 is opened in the middle of the placement rack 4.

[0030] The screw rod 18 is installed to adjust the position of the C-shaped plate 19, and the C-shaped plate 19 is fastened and clamped to the magnetic particle flaw detector 5.

[0031] In this embodiment, an anti-slip pad is installed on the inner wall of one side of the placement rack 4 close to the bracket 13.

[0034] The telescopic rod ensures that the stabilizing plate 15 moves smoothly.

[0035] It should be noted that the utility model is a magnetic particle flaw detection device that can be used for autonomous detection on an I-beam frame. When in use, the bidirectional screw rod 7 is rotated so that the two sets of sliders 8 move toward the center, so that the two sets of sliders 8 drive the two sets of drive motors 2 to move toward the middle, so that the two sets of travel rollers 3 contact the front and rear ends of the I-beam, thereby increasing the scope of use;

[0036] Before the drive motor 2 is started, the adjusting screw 14 is rotated to move the stabilizing plate 15 downward, so that the cleaning brush 16 moves downward to contact the upper end surface of the I-beam. When the traveling roller 3 rotates to move forward, the cleaning brush 16 can clean the area to be inspected by the magnetic particle flaw detector 5 to ensure a clearer and more thorough inspection.
