Description

Technical Field

[0001] This utility model relates to the field of weld inspection, and more specifically, to a steel structure weld inspection device. Background Technology

[0002] In the production process of some light steel building structures, it is often necessary to produce components such as connectors and connecting frames in the factory by welding. These components are used to assemble and connect beams, columns and other components. Since the raw materials for the production of these components are relatively thin, the requirements for welding quality are high. Therefore, it is necessary to inspect the welds.

[0003] For example, the Chinese utility model patent with publication number CN222719495U can adjust the angle of the steel structure by setting a rotating clamping device, which facilitates the inspection of welds at different positions. In addition, by setting a limiting mechanism, the stability of the steel structure after the angle is adjusted can be guaranteed, ensuring the accuracy of the inspection results. However, when dealing with long steel structures, such as square tubes, the clamping length is limited, which cannot achieve effective clamping and has certain shortcomings. In view of this, we propose a steel structure weld inspection device. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the current clamping length is limited but effective clamping cannot be achieved.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a steel structure weld inspection device, comprising a base, a groove on the upper surface of the base, a fixed plate fixedly connected to the upper surface of the base, a rotating ring rotatably connected inside the fixed plate, the front and rear surfaces of the rotating ring extending to the outside of the fixed plate, a sliding groove on the inner wall of the rotating ring, an active clamping plate slidably connected inside the sliding groove, a passive clamping plate fixedly connected to the inner wall of the sliding groove, both the active and passive clamping plates extending to the outside of the sliding groove, an adjusting threaded rod rotatably connected to the upper surface of the active clamping plate, the upper end of the adjusting threaded rod threaded through to the outer surface of the rotating ring, a knob fixedly connected to the upper end of the adjusting threaded rod, and a rotating assembly provided on the base.

[0006] As a preferred technical solution of this application, the rotating component includes a self-locking motor, which is fixedly connected to the front surface of the base. The base has a drive cavity inside, and a first synchronous wheel is rotatably connected to the inner wall of the drive cavity.

[0007] As a preferred technical solution of this application, the output end of the self-locking motor rotates through the interior of the drive cavity and is fixedly connected to the first synchronous wheel, and the inner wall of the drive cavity is rotatably connected to a rotating shaft.

[0008] As a preferred technical solution of this application, two second synchronous wheels are fixedly sleeved on the outer surface of the rotating shaft, and the outer surface of the rotating ring is provided with a groove.

[0009] As a preferred technical solution of this application, a first synchronous belt is provided between the grooved belt and the second synchronous pulley, and a second synchronous belt is provided between the first synchronous pulley and the second synchronous pulley.

[0010] As a preferred technical solution of this application, the front and rear surfaces of the base are provided with clearance grooves, and the upper side of the clearance grooves extends to the upper surface of the base.

[0011] As a preferred technical solution of this application, two columns are fixedly connected to the base, and a top plate is fixedly connected to the upper end of the columns. A horizontal moving mechanism is provided on the top plate.

[0012] As a preferred technical solution of this application, a flaw detector body is provided on the base, and the flaw detector body is electrically connected to the horizontal moving mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. It can clamp rectangular steel structures and long strip steel structures by means of a rotating ring and internally installed active and passive clamping plates. It can still clamp stably when the steel structure is long, thus improving the applicability of the detection device.

[0016] 2. A self-locking motor can be used to indirectly drive the rotating ring to rotate, thereby indirectly completing the flipping of the steel structure and achieving all-round inspection. At the same time, the self-locking property of the self-locking motor itself eliminates the need to complete the unlocking step during rotation, reducing the operation procedures.

[0029] Example 2

[0030] The steel structure weld inspection device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the rotating assembly includes a self-locking motor 10 for driving, which is fixedly connected to the front surface of the base 1. A driving cavity 11 is formed inside the base 1. A first synchronous pulley 12 for power transmission is rotatably connected to the inner wall of the driving cavity 11. The output end of the self-locking motor 10 rotatably passes through the interior of the driving cavity 11 and is fixedly connected to the first synchronous pulley 12. A rotating shaft 13 is rotatably connected to the inner wall of the driving cavity 11. Two second synchronous pulleys 14 for power transmission are fixedly sleeved on the outer surface of the rotating shaft 13. A groove 15 is formed on the outer surface of the rotating ring 4. A first synchronous belt 16 is sleeved between the groove 15 and the second synchronous pulleys 14. The first synchronous pulley 12 and the second synchronous pulleys... A second synchronous belt 17 is provided between 14. Both the front and rear surfaces of the base 1 are provided with clearance grooves 18. The upper side of the clearance grooves 18 extends to the upper surface of the base 1. Two columns 19 are fixedly connected to the base 1. A top plate 20 is fixedly connected to the upper end of the columns 19. A horizontal moving mechanism 21 is provided on the top plate 20. A flaw detector body 22 is provided on the base 1.

[0032] The process of using the steel structure weld inspection device provided by this utility model is as follows:

[0033] When inspecting sheet-like or rectangular steel structures, the steel structure can be inserted from the right side and brought into contact with the upper surface of the passive clamping plate 7. Then, the active clamping plate 6 is lowered by rotating the two adjusting threaded rods 8, thereby clamping the steel structure. When dealing with long strip-shaped steel structures, the long strip-shaped steel structure can be inserted from the front into the rotating ring 4 and passed between the active clamping plate 6 and the passive clamping plate 7. Then, the active clamping plate 6 is moved by adjusting the threaded rods 8 to clamp the long strip-shaped steel structure. After clamping, the self-locking motor 10 can be used to synchronously drive the first synchronous wheel 12 to rotate. The first synchronous wheel 12, in conjunction with the second synchronous belt 17, drives the second synchronous wheel 14 to rotate. After the second synchronous wheel 14 rotates, it will indirectly drive the rear second synchronous wheel 14 to rotate through the rotating shaft 13. After the rear second synchronous wheel 14 rotates, the first synchronous belt 16 can be used to drive the rotating ring 4 to rotate, thereby indirectly driving the steel structure to rotate.
