Description

Technical Field

[0001] This utility model relates to the field of steel structure flaw detection technology, and in particular to a steel structure flaw detection device. Background Art

[0002] Steel structures, primarily constructed of steel, are a major type of building structure. After a certain period of use, steel structures can develop internal or external cracks due to material aging, environmental erosion, and biological corrosion, posing safety hazards. To mitigate these hazards, flaw detection devices are needed to inspect steel structures. For example, a steel structure inspection device as described in Chinese patent application number CN202321715194.4 includes a connecting cylinder mounted on the upper wall of an extension rod, with internal threads inside the connecting cylinder; the probe end of a steel structure weld flaw detector is screwed into the connecting cylinder; the extension rod comprises a first cylinder, a second cylinder, and a third cylinder, with the second cylinder slidably mounted inside the first cylinder, and the third cylinder slidably mounted inside the second cylinder; a main rubber sleeve and a main retaining ring are fitted onto the outer side of the second cylinder located inside the first cylinder; and a secondary rubber sleeve and a secondary retaining ring are fitted onto the outer side of the third cylinder located inside the second cylinder.

[0003] However, when using an extension rod to drive an ultrasonic flaw detector to perform flaw detection on steel structures at high altitudes, the process of controlling the ultrasonic flaw detector to perform flaw detection on steel structures at different heights by relying on the extension rod's extension is not only time-consuming and labor-intensive, but also inconvenient to control the ultrasonic flaw detector to perform flaw detection on steel structures at different heights, and is prone to causing the ultrasonic flaw detector to fall from a height. Utility Model Content

[0004] To address the problems mentioned in the background art, where controlling the ultrasonic flaw detector to inspect steel structures of different heights via the extension rod is time-consuming, labor-intensive, inconvenient, and prone to causing the ultrasonic flaw detector to fall from a height, this utility model provides the following technical solution:

[0005] A steel structure flaw detection device includes an ultrasonic probe fixedly mounted on a fixed frame for flaw detection of the steel structure.

[0009] Furthermore, the support assembly includes a fixed column fixedly installed at the bottom of the movable column. The column body of the fixed column has a sliding groove for the adjustment assembly two to move up and down. The front two ends of the sliding groove two have limiting grooves two for restricting the adjustment assembly two. The right end of the fixed column has a locking hole two for locking the adjustment assembly two, and there are several locking holes two.

[0010] Furthermore, the second adjustment component includes a movable block disposed in the second slide groove for moving up and down. The front and rear ends of the movable block are fixedly installed with sliders for sliding in the second limiting groove. The end of the slider away from the second driving component is fixedly installed with a movable plate for driving the movable block to move up and down. The movable plate is provided with two locking rods for locking the movable plate.

[0011] Furthermore, the movable block is provided with a rotating shaft for driving the first drive component to rotate, and a motor for driving the rotating shaft to rotate is fixedly installed at the end of the rotating shaft away from the second drive component.

[0012] Furthermore, the drive assembly includes a fixed frame fixedly mounted on the movable block, and a movable wheel for rotation is provided inside the frame of the fixed frame, and the movable wheel is connected to the rotating shaft.

The top of the fixed frame has a locking hole for cooperating with the locking rod to lock the limiting block, and there are several locking holes.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] By setting up a fixed frame, adjustment device, and drive device, when flaw detection of the steel structure is required, the moving column moves along the slide groove one, which controls the left and right movement of the two fixed columns, thus controlling the two drive devices to lock onto the steel structure. Then, the locking rod one is inserted into the locking hole one and tightened. Next, the moving plate controls the moving block to move up and down along the slide groove two, which locks the moving wheel one and moving wheel two onto the steel structure. Then, the two locking rods two are inserted into the locking hole two and tightened. Then, the ultrasonic probe is controlled by the buttons on the steel structure flaw detector. Finally, the forward and reverse rotation of the motor is controlled by the buttons on the steel structure flaw detector, which controls the movement of the moving wheel one and moving wheel two along the steel structure. This enables rapid flaw detection of steel structures at different depths and prevents the ultrasonic probe from falling from a height. Attached Figure Description

Detailed Implementation

[0029] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0030] Please see Figures 1-6 This utility model provides a steel structure flaw detection device.

[0031] The device includes an ultrasonic probe 200 fixedly mounted on a mounting frame 300 for flaw detection of steel structures. A steel structure flaw detector 100 for controlling the ultrasonic probe 200 to perform flaw detection on the steel structure is provided on the left side of the mounting frame 300. An adjustment device 400 for clamping the steel structure is provided inside the mounting frame 300, and there are two adjustment devices 400.

[0032] The steel structure flaw detector 100 and the ultrasonic probe 200 are connected by wireless signal, so the operation of the ultrasonic probe 200 can be controlled by the steel structure flaw detector 100.

[0033] The fixed frame 300 has a sliding groove 302 for the moving column 411 to move. The front and rear ends of the sliding groove 302 have limiting grooves 303 for the moving limiting block 412 to move.

There are several locking holes 301, and the several locking holes 301 are distributed in a linear array at the top of the fixed frame 300.

[0034] The adjustment device 400 includes an adjustment component 410 disposed within the fixed frame 300 for left and right movement, and a support component 420 for assisting the drive device 500 to move along the steel structure is fixedly installed at the bottom end of the adjustment component 410.

[0035] Adjustment component 410 includes a movable column 411 disposed within the fixed frame 300 for left and right movement. The movable column 411 can move within the slide groove 302, thereby controlling the two drive devices 500 to be locked onto the steel structure according to the width of the steel structure. Limiting blocks 412 for assisting the left and right movement of the movable column 411 are fixedly installed at both ends of the movable column 411. The limiting blocks 412 can move within the limiting groove 303 to prevent the movable column 411 from disengaging from the limiting groove 302. A locking rod 413 for locking the limiting block 412 is provided at the top of the movable column 411. The locking rod 413 can be inserted into the locking hole 301 and threadedly connected thereto, thereby locking the movable column 411.

[0036] The support assembly 420 includes a fixed column 421 fixedly installed at the bottom of the movable column 411. The column body of the fixed column 421 has a sliding groove 422 for the adjustment assembly 510 to move up and down. The front two ends of the sliding groove 422 have limiting grooves 423 for restricting the adjustment assembly 510. The right end of the fixed column 421 has a locking hole 424 for locking the adjustment assembly 510. There are several locking holes 424, and the several locking holes 424 are arranged in a linear array. The columns are distributed on the fixed columns 421; thus, when it is necessary to lock the two drive devices 500 onto the steel structure according to the width of different steel structures, the locking rod 413 can be loosened and removed from the locking hole 301, and then the moving column 411 can be moved along the slide groove 302 to control the two fixed columns 421 to move left and right, so that the two drive devices 500 are locked onto the steel structure, so as to facilitate the control of the ultrasonic probe 200 to move along the steel structure, thereby realizing the flaw detection of the steel structure.

[0037] The drive device 500 includes a second drive component 530 fixedly installed on the support assembly 420 near the end of the ultrasonic probe 200. The bottom end of the second drive component 530 is provided with a second drive component 520 for cooperating with the second drive component 530 to assist the ultrasonic probe 200 in moving along the steel structure. The support assembly 420 is provided with an adjustment component 510 for driving the first drive component 520 to move up and down.

[0038] Adjustment component 2 510 includes a movable block 513 disposed in slide groove 2 422 for vertical movement, and the width of movable block 513 is the same as the width of slide groove 2 422 so that movable block 513 can move vertically along slide groove 2 422; sliders 514 for sliding in limiting groove 2 423 are fixedly installed at the front and rear ends of movable block 513; a movable plate 515 for driving movable block 513 to move vertically is fixedly installed at the end of slider 514 away from drive component 2 520; locking rods 2 516 for locking movable plate 515 are provided on the plate body of movable plate 515, and there are two locking rods 2 516 distributed front and rear on the plate body of movable plate 515. At the same time, the two locking rods 2 516 can be inserted into locking hole 2 424 and threadedly connected to it to lock movable plate 515.

[0039] The movable block 513 is provided with a rotating shaft 512 for driving the drive assembly 520 to rotate. The rotating shaft 512 is connected to the movable block 513 through a bearing to facilitate the rotation of the rotating shaft 512. A motor 511 for driving the rotating shaft 512 to rotate is fixedly installed at the end of the rotating shaft 512 away from the drive assembly 520. The motor 511 can be connected to the steel structure flaw detector 100 through a controller so that the steel structure flaw detector 100 can control the motor 511 to rotate in both directions.

[0040] The drive assembly 520 includes a fixed frame 521 fixedly mounted on the movable block 513. The fixed frame 521 has a movable wheel 522 for turning inside the frame.

[0041] Drive assembly 2 530 includes a fixed frame 2 531 fixedly installed on the support assembly 420 at the end away from the motor 511. The fixed frame 2 531 has a movable wheel 2 532 for cooperating with the movable wheel 1 522 to move along the steel structure. Thus, when flaw detection of the steel structure is required, the movable column 411 moves along the slide groove 1 302, controlling the left and right movement of the two fixed columns 421, causing the two drive devices 500 to be locked onto the steel structure. Then, the locking rod 1 413 is inserted into the locking hole 1 301 and tightened. Finally, the movable plate 515 controls the movable block 513 to move along... The slide rail 422 moves up and down, which can lock the first moving wheel 522 and the second moving wheel 532 onto the steel structure. Then, the two locking rods 516 are inserted into the locking holes 424 and tightened. Then, the ultrasonic probe 200 is controlled to work by the button on the steel structure flaw detector 100. Finally, the motor 511 is controlled to rotate forward and backward by the button on the steel structure flaw detector 100, which can control the first moving wheel 522 and the second moving wheel 532 to move along the steel structure. This enables rapid flaw detection of steel structures at different heights and prevents the ultrasonic probe 200 from falling from a height.

[0042] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
