Description

Technical Field

[0001] This utility model relates to the field of steel structure inspection technology, and in particular to a non-destructive testing device for steel structures. Background Technology

[0002] Steel structure flaw detection is a non-destructive testing technique that utilizes changes in physical properties (such as thermal, acoustic, optical, electrical, and magnetic reactions) caused by internal structural anomalies or defects in materials. Through modern technology and equipment, it performs a comprehensive inspection of the internal and surface of steel structures. This method is widely used in various steel structure buildings such as bridges, factories, buildings, and warehouses, and is a key measure to ensure building safety and extend service life.

[0003] Currently, steel structure inspections are mostly conducted manually using handheld flaw detectors. After one side of the steel structure is inspected, it needs to be manually flipped over, which makes the operation inconvenient and affects the inspection efficiency. Therefore, we propose a non-destructive testing device for steel structures. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a non-destructive testing device for steel structures.

[0005] This utility model is achieved by the following technical solution: a non-destructive testing equipment for steel structures, including a mounting bracket, through slots at both ends of the mounting bracket, a testing component inside the mounting bracket, a moving component at the upper end of the testing component, a hydraulic telescopic rod fixedly connected to the inner wall of the mounting bracket, and a clamping plate fixedly connected to the output end of the hydraulic telescopic rod.

[0006] The detection assembly includes a mounting plate, a drive motor is fixedly connected to the left end of the mounting plate, a drive gear is fixedly connected to the output end of the drive motor, a driven gear meshes with the inner wall of the drive gear, a fixed ring is rotatably connected to the surface of the driven gear, a mounting bracket is fixedly connected to the right end of the driven gear, a flaw detector is fixedly connected to the bottom of the mounting bracket, and a support plate is fixedly connected to the left end of the fixed ring.

[0007] The above technical solution involves starting the drive motor, which in turn drives the active gear to rotate. Since the active gear meshes with the driven gear, it causes the driven gear to rotate within the inner wall of the fixed ring, thus rotating the flaw detector and performing a comprehensive inspection of the steel structure. This avoids the need for manual rotation of the steel structure, thereby improving inspection efficiency. The fixed ring acts as a limit for the driven gear, ensuring its stability during rotation. Because the active gear has fewer teeth than the driven gear, it achieves a deceleration effect, causing the driven gear to rotate slowly and preventing excessive rotation that could affect inspection accuracy. The through slot facilitates the placement of the steel structure between the two clamping plates by passing it through the fixed ring.

[0008] As a further improvement to the above solution, the moving component includes a lead screw, the surface of which is threadedly connected to a mounting base, a servo motor is fixedly connected to the left end of the lead screw, and a limit rod is slidably connected to the inner wall of the mounting base.

[0009] The above technical solution involves starting a servo motor, which drives a lead screw to rotate, causing the mounting base to move. This, in turn, causes the entire detection assembly to move horizontally, facilitating the detection of different locations on the steel structure and thus improving its practicality.

[0010] As a further improvement to the above solution, the two ends of the lead screw are rotatably connected to the inner wall of the mounting bracket, and the bottom of the mounting base is fixedly connected to the top of the mounting plate.

[0011] With the above technical solution, since the mounting base is fixedly connected to the top of the mounting plate and the support plate, the mounting base will move when it moves.

[0012] As a further improvement to the above solution, the bottom of the mounting base is fixedly connected to the top of the support plate.

[0013] The above technical solution uses a support plate to support the fixed ring, ensuring stability during use.

[0014] As a further improvement to the above solution, the right end of the servo motor is fixedly connected to the left end of the mounting bracket.

[0015] As a further improvement to the above scheme, two limiting rods are provided, and the two limiting rods are symmetrically distributed with the mounting base as the center.

[0016] The above technical solution uses a limiting rod to limit the position of the mounting base, ensuring its stability during movement and preventing tilting.

[0017] As a further improvement to the above solution, two hydraulic telescopic rods and two clamping plates are provided, and they are symmetrically distributed around the mounting bracket.

[0018] The above technical solution uses a hydraulic telescopic rod to move the clamping plates, thereby fixing the steel structure with the two clamping plates, which facilitates subsequent testing.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a detection component. Specifically, by activating a drive motor, the drive motor rotates the active gear. Since the active gear meshes with the driven gear, it causes the driven gear to rotate on the inner wall of the fixed ring, thus rotating the flaw detector and performing a comprehensive inspection of the steel structure. This avoids the need for manual rotation of the steel structure, thereby improving inspection efficiency.

[0021] This invention improves practicality by incorporating a moving component, specifically by activating a servo motor that drives a lead screw to rotate, causing the mounting base to move and thus moving the entire detection component horizontally. This facilitates the detection of different locations on the steel structure. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5The non-destructive testing equipment for steel structures in this embodiment includes a mounting bracket 1, through slots 2 at both ends of the mounting bracket 1, a testing component 3 inside the mounting bracket 1, a moving component 4 at the upper end of the testing component 3, a hydraulic telescopic rod 5 fixedly connected to the inner wall of the mounting bracket 1, and a clamping plate 6 fixedly connected to the output end of the hydraulic telescopic rod 5.

[0032] The inspection component 3 includes a mounting plate 301. A drive motor 302 is fixedly connected to the left end of the mounting plate 301. A drive gear 303 is fixedly connected to the output end of the drive motor 302. A driven gear 304 meshes with the inner wall of the drive gear 303. A fixing ring 305 is rotatably connected to the surface of the driven gear 304. A mounting bracket 306 is fixedly connected to the right end of the driven gear 304. A flaw detector 307 is fixedly connected to the bottom of the mounting bracket 306. A support plate 308 is fixedly connected to the left end of the fixing ring 305. The steel structure is placed through the fixing ring 305. Between the two clamping plates 6, the hydraulic telescopic rod 5 is activated. The output end of the hydraulic telescopic rod 5 pushes the clamping plates 6 to move, clamping and fixing the steel structure through the two clamping plates 6. Then, the drive motor 302 is activated, driving the drive gear 303 to rotate. Since the drive gear 303 meshes with the driven gear 304, it drives the driven gear 304 to rotate on the inner wall of the fixed ring 305, causing the flaw detector 307 to rotate and perform a comprehensive inspection of the steel structure. This avoids the need for manual flipping of the steel structure, thereby improving the inspection efficiency.

[0033] The moving component 4 includes a lead screw 401, with a mounting base 402 threaded onto its surface. A servo motor 403 is fixedly connected to the left end of the lead screw 401. A limit rod 404 is slidably connected to the inner wall of the mounting base 402. When the servo motor 403 is started, it drives the lead screw 401 to rotate, causing the mounting base 402 to move. This, in turn, causes the entire detection component 3 to move horizontally, facilitating the detection of different positions on the steel structure and improving its practicality.

[0034] The two ends of the lead screw 401 are rotatably connected to the inner wall of the mounting bracket 1, and the bottom of the mounting base 402 is fixedly connected to the top of the mounting plate 301.

[0035] The bottom of the mounting base 402 is fixedly connected to the top of the support plate 308.

[0036] The right end of the servo motor 403 is fixedly connected to the left end of the mounting bracket 1.

[0037] There are two limit rods 404, which are symmetrically distributed around the mounting base 402. The limit rods 404 limit the mounting base 402, ensuring the stability of the mounting base 402 when it moves.

[0038] Two hydraulic telescopic rods 5 and two clamping plates 6 are provided, and they are symmetrically distributed with the mounting bracket 1 as the center.

[0039] The implementation principle of the non-destructive testing equipment for steel structures in this embodiment is as follows: During use, the steel structure is placed between two clamping plates 6 through a fixing ring 305. The hydraulic telescopic rod 5 is activated, and its output end pushes the clamping plates 6 to move, clamping and fixing the steel structure. Then, the drive motor 302 is activated, driving the drive gear 303 to rotate. Since the drive gear 303 meshes with the driven gear 304, the driven gear 304 rotates on the inner wall of the fixing ring 305, causing the flaw detector 307 to rotate and perform a comprehensive inspection of the steel structure. This avoids manual flipping of the steel structure, thus improving inspection efficiency. Then, the servo motor 403 is activated, driving the lead screw 401 to rotate, causing the mounting base 402 to move, thereby causing the entire inspection component 3 to move horizontally, facilitating inspection of different positions on the steel structure and improving practicality.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
