Description

Technical Field

[0001] This utility model relates to a clamping device, specifically a clamping device for steel structure inspection, and belongs to the technical field of steel structure inspection. Background Technology

[0002] Steel structures are structures made of steel, possessing advantages such as high strength, good toughness, and corrosion resistance, and are widely used in industrial fields. After steel structures are manufactured, various data need to be tested to ensure their quality and safety. When detecting internal defects in steel structures, ultrasonic testing is generally used because it has high sensitivity, is easy to operate, has a fast testing speed, and does not damage the steel structure itself. Currently, when monitoring various small steel structure parts, they generally need to be clamped and fixed for testing purposes, which requires the use of clamping devices.

[0003] In existing methods of ultrasonic testing of steel structures, the steel structure is typically placed under the ultrasonic probe, which is then pressed against the structure for detection. However, for steel structures with complex shapes and uneven surfaces, the ultrasonic probe may not be able to completely cover the entire testing area in one direction. Therefore, it is necessary to rotate and flip the steel structure to allow for testing from different directions. Currently, this is usually done manually by staff, which is inefficient. To address this issue, we have developed a clamping device for steel structure testing. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a clamping device for steel structure inspection, the specific technical solution of which is as follows: A clamping device for steel structure inspection includes a housing, an electric motor installed on the inner bottom wall of the housing, a rotating plate connected to the output end of the electric motor, a sliding mechanism between the rotating plate and the housing, three placement buckets rotatably connected to the upper surface of the rotating plate, a lifting mechanism inside the placement buckets, a transmission mechanism inside the housing located below the three placement buckets, and a fixing mechanism on the upper surface of the rotating plate.

[0005] Preferably, the sliding mechanism includes a limiting ring, the lower surface of which is fixedly connected to the housing, the inner wall of which is slidably connected to the rotating plate, and a ball bearing is movably embedded in the inner wall of the housing, the outer surface of which is in contact with the rotating plate.

[0006] Preferably, the lifting mechanism includes an electric telescopic rod, which is installed on the inner bottom wall of the placement bucket. The telescopic end of the electric telescopic rod is connected to a top plate, and the outer surface of the top plate is slidably connected to the placement bucket. A control panel is installed on the outside of the placement bucket.

[0007] Preferably, the transmission mechanism includes a gear ring, the lower surface of which is connected to a support plate, and the lower surface of the support plate is connected to the inner bottom wall of the housing.

[0008] Preferably, a gear is connected to the lower surface of the placement bucket, the outer surface of the gear is rotatably connected to the rotating plate, and the outer surface of the gear is meshed with a gear ring.

[0009] Preferably, the fixing mechanism includes a threaded rod, the lower surface of which is fixedly connected to the rotating plate, an adjusting plate is slidably connected to the outer surface of the threaded rod, and three pressure plates are connected to the outer surface of the adjusting plate.

[0010] Preferably, both the upper and lower surfaces of the adjusting plate are provided with limiting members, and the inner wall of the limiting member is threadedly connected to the threaded rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This steel structure inspection clamping device consists of a rotating plate and a placement bucket. The rotating plate drives the placement bucket to rotate, and then controls the lifting mechanism to move the steel structure upward, allowing it to rise out of the placement bucket. Simultaneously, the upper end of the steel structure contacts and presses against the fixing mechanism, facilitating the clamping and fixing of the steel structure. An ultrasonic measuring device is then used to inspect the steel structure. After inspection, the device rotates again. During the rotation of the placement bucket around the center of the shell, the transmission mechanism causes the placement bucket to rotate, causing the steel structure to rotate as well. This allows for inspection of the back side of the steel structure, achieving the effect of flipping the steel structure, increasing efficiency, and solving the problem of low efficiency caused by manual flipping in existing methods.

[0012] 2. This steel structure inspection clamping device incorporates components such as a fixing mechanism and a sliding mechanism. A limiting ring restricts the rotating plate to prevent it from shifting and disconnecting from the motor's output shaft. Ball bearings support the edges of the rotating plate to prevent it from collapsing and reduce friction between the rotating plate and the housing, facilitating its rotation. By turning the adjusting plates, the vertical positions of the two adjusting plates can be adjusted to accommodate steel structures of different heights, thus increasing its applicability.

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] Please see Figures 1-5 The system includes a housing 1, an electric motor 2 installed on the inner bottom wall of the housing 1, a rotating plate 3 connected to the output end of the electric motor 2, a sliding mechanism 4 between the rotating plate 3 and the housing 1, three placement buckets 5 rotatably connected to the upper surface of the rotating plate 3, a lifting mechanism 6 inside the placement buckets 5, a transmission mechanism 7 inside the housing 1 located below the three placement buckets 5, a fixing mechanism 8 on the upper surface of the rotating plate 3, and three support legs 9 installed at the lower part of the housing 1 to support the housing 1 and other components. The electric motor 2 can drive the rotating plate 3 to rotate, causing the rotating plate 3 to drive the three placement buckets 5 to rotate around the center of the housing 1. At the same time, under the action of the transmission mechanism 7, the placement buckets 5 also rotate on their own axis. When the rotating plate 3 rotates, it is supported by the sliding mechanism 4, which reduces the friction between the rotating plate 3 and the housing 1.

[0017] The sliding mechanism 4 includes a limiting ring 402. The lower surface of the limiting ring 402 is fixedly connected to the housing 1. The inner wall of the limiting ring 402 is slidably connected to the rotating plate 3. The inner wall of the housing 1 is movably embedded with balls 401. The outer surface of the balls 401 is in contact with the rotating plate 3. The limiting ring 402 is used to restrict the rotating plate 3 to prevent it from shifting and causing it to disconnect from the output shaft of the motor 2. The balls 401 are used to support the edge of the rotating plate 3 to prevent it from collapsing downwards, and at the same time reduce the friction between the rotating plate 3 and the housing 1 to facilitate the rotation of the rotating plate 3.

[0018] The lifting mechanism 6 includes an electric telescopic rod 601, which is installed on the inner bottom wall of the placement tank 5. The telescopic end of the electric telescopic rod 601 is connected to a top plate 602. The outer surface of the top plate 602 is slidably connected to the placement tank 5. A control panel 603 is installed on the outside of the placement tank 5. The electric telescopic rod 601 can move up or down with the top plate 602, thereby driving the steel structure to move up and down. The control panel 603 can control the extension and retraction of the electric telescopic rod 601 and is electrically connected to the electric telescopic rod 601.

[0019] The transmission mechanism 7 includes a gear ring 701, and a support plate 702 is connected to the lower surface of the gear ring 701. The lower surface of the support plate 702 is connected to the inner bottom wall of the housing 1. There are three support plates 702, which can support and fix the gear ring 701. The gear ring 701 is ring-shaped and has multiple teeth on its outer surface.

[0020] A gear 703 is connected to the lower surface of the placement bucket 5. The outer surface of the gear 703 is rotatably connected to the rotating plate 3. The outer surface of the gear 703 is meshed with the gear ring 701. There is a pin on the upper part of the gear 703, which is connected to the placement bucket 5 through the pin. At the same time, it facilitates the rotation of the gear 703. When the gear 703 rotates around the center of the housing 1, it will rotate under the meshing action with the gear ring 701, which will drive the placement bucket 5 to rotate.

[0021] The fixing mechanism 8 includes a threaded rod 801, the lower surface of which is fixedly connected to the rotating plate 3. An adjusting plate 802 is slidably connected to the outer surface of the threaded rod 801. Three pressure plates 803 are connected to the outer surface of the adjusting plate 802. The three pressure plates 803 are respectively located above the three placement barrels 5. The threaded rod 801 can rotate together with the rotating plate 3 so that the three pressure plates 803 are always above the three placement barrels 5.

[0022] Both the upper and lower surfaces of the adjusting plate 802 are provided with limiting members 804. The inner wall of the limiting member 804 is threadedly connected to the threaded rod 801. There are two limiting members 804, which can limit the adjusting plate 802 and clamp the adjusting plate 802 in the middle to fix the adjusting plate 802. By turning the adjusting plate 802, the upper and lower positions of the two adjusting plates 802 can be adjusted, thereby adjusting the position of the adjusting plate 802.

[0023] The electric motor 2 and the electric telescopic pole 601 in this application are common electrical devices in the prior art. This application will not elaborate on their models or internal structures, and they can also be replaced by other power sources.

[0024] In use, this invention consists of three workstations, each corresponding to a placement container 5. At the first workstation, the steel structure to be inspected is placed inside the placement container 5. Then, the rotating plate 3 rotates, causing the placement container 5 to rotate 120 degrees to reach the second workstation. Next, the lifting mechanism 6 is controlled to move the steel structure upwards, lifting it out of the placement container 5. Simultaneously, the upper end of the steel structure contacts and is pressed against the fixing mechanism 8, facilitating clamping and fixing of the steel structure. An ultrasonic measuring device is then used to inspect the steel structure. After inspection, the lifting mechanism 6 moves the steel structure back to its original position. Rotate 120 degrees to bring the steel structure to the third station. During the rotation of the placement bucket 5 around the center of the shell 1, the placement bucket 5 rotates under the action of the transmission mechanism 7. After the steel structure reaches the third station, it has already rotated. Repeat the above inspection steps and inspect the back of the steel structure again, thus achieving the effect of flipping the steel structure. Afterwards, the steel structure rotates back to the first station, and the steel structure inside the placement bucket 5 is replaced. There are three stations, one dedicated to replacing the steel structure, and the other two performing two inspections on the front and back of the steel structure simultaneously to increase inspection efficiency.
