Description

Technical Field

[0001] This utility model relates to the field of steel structure bending detection technology, specifically a steel structure bending detection device. Background Technology

[0002] The steel structure bending test machine is a specialized device used to test the mechanical properties of materials such as steel and steel pipes. It mainly tests their bending strength, plastic deformation and other characteristics. It is widely used in steel metallurgy, steel frame structure, precast components, building materials production and quality inspection departments to test the cold bending performance and reverse bending performance of steel.

[0003] An investigation revealed a utility model patent (publication number: CN221945762U) disclosing a metal bending testing machine, comprising: a base, a frame fixedly mounted on the rear side of the top of the base, and a top hole on the left side of the top of the frame; a straightening mechanism disposed above the frame; and an adjustment mechanism disposed above the base. The straightening mechanism includes a brake motor, which is fixedly mounted on the left side of the top of the frame, and the output shaft of the brake motor is fixedly sleeved with a rotating shaft. This utility model, by incorporating a brake motor, a rotating rod, vertical plates, and a circular block, allows the rotating shaft to drive the rotating rod and the circular block to rotate when the brake motor is activated. This enables the two vertical plates to move towards or away from each other. When the two vertical plates move towards each other, the metal plate is straightened, achieving automatic straightening of the metal plate and preventing the metal plate from tilting and affecting the accuracy of experimental data, thereby improving the accuracy of the experimental results obtained by the operator.

[0004] Although the aforementioned patent avoids tilting of the metal plate during the testing process by aligning the metal plate, its actual safety is not improved. Due to its open structure, when the device is performing bending tests on the steel structure, some of the more brittle composite steel materials will crack and fly when bent and compressed, and the flying debris can easily cause injury to the staff.

[0005] Therefore, this utility model provides a steel structure bending detection device to solve the above problems. Utility Model Content

When the device is used for bending tests, it can provide a protective enclosure, and conversely, it can raise the guardrail, facilitating manual operation in the work area.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-6As shown, this utility model provides a steel structure bending detection device, including a housing 1. The top of the housing 1 is fixedly connected to a top plate 12 via a support rod 11, and a first cylinder 13 is fixedly connected to the upper surface of the top plate 12. The lifting end of the first cylinder 13 extends through to the bottom of the top plate 12 and is fixedly connected to a pressure head 14 and a guide frame 15. A worktable 2 is slidably disposed at the top center of the housing 1, and a first clamp 22 adapted for steel structure positioning is fixedly connected to the top of the worktable 2. A protective component 3 includes a guide shaft 31, which is fixedly connected to the outer wall of the housing 1 and the top plate 12. A sliding sleeve 32 is slidably connected to the outside of the guide shaft 31, and a protective railing 33 is fixedly connected to the outer wall of the sliding sleeve 32. By sliding the protective railing 33 up and down, the protective railing 33 can cover the working area of ​​the device, thereby preventing accidental injury to personnel from broken debris.

[0019] Furthermore, a positioning cover 16 is fixedly connected between the chassis 1 and the top plate 12. The protective railing 33 has a C-shaped structure, and both ends of the protective railing 33 are slidably connected to the outer wall of the positioning cover 16.

[0020] Furthermore, the bottom of the worktable 2 is fixedly connected to the lifting end of the second cylinder 21, and the top center of the machine box 1 is provided with a cavity adapted to the installation of the second cylinder 21. The second clamp 23 is placed inside the cavity. The worktable 2 is slidably connected to the inner wall of the cavity. The height of the worktable 2 can be adjusted by lifting the second cylinder 21, so that the surface of the workpiece on the first clamp 22 or the second clamp 23 is consistent with the downward stroke of the pressure head 14. The upper surface of the worktable 2 is adapted to the first clamp 22 or the second clamp 23 according to the cross section of the steel structure, so that it can be adapted to rectangular and circular steel structures for bending detection.

[0021] Furthermore, it also includes a transmission assembly 4, which includes a first rack 41, fixedly connected to the upper surface of the guide frame 15. A first gear 42 meshes with the outside of the first rack 41, and a second gear 43 meshes with the other side of the first gear 42. A third gear 44 is fixedly connected to the outer wall of the second gear 43, and a second rack 45 meshes with the outside of the third gear 44. The bottom of the second rack 45 is fixedly connected to the inner wall of the guardrail 33. The top of the top plate 12 has a through groove adapted to allow the first rack 41 and the second rack 45 to slide vertically through it, and the inner wall of the through groove is provided with guide blocks adapted to limit the vertical sliding of the first rack 41 and the second rack 45. The second gear 43 and the first gear 44... The three gears 44 are coaxially distributed, and the center of the second gear 43 and the first gear 42 are both rotatably equipped with a support shaft 46. The two ends of the support shaft 46 are fixedly connected to the inner wall of the positioning cover 16 by brackets. The size of the third gear 44 is larger than that of the second gear 43. When the first cylinder 13 starts and drives the guide frame 15 to descend, it simultaneously drives the first rack 41 to descend. During the descent of the first rack 41, it drives the first gear 42 to rotate, and further drives the third gear 44 to rotate through the meshing of the second gear 43. At the same time as the third gear 44 rotates, it drives the second rack 45 to adjust up and down. Thus, while the guide frame 15 moves up and down, the guardrail 33 moves up and down.

[0022] Working principle: The guardrail 33 is initially at the top, and the pressure head 14 is also at the top. The first clamp 22 or the second clamp 23 is selected according to the cross section of the steel structure to be tested, and then it is installed on the surface of the workbench 2. The steel structure is then placed and fixed above the first clamp 22 or the second clamp 23. When the first cylinder 13 descends, it drives the pressure head 14 to press down and perform a bending test on the steel structure, the guide frame 15 descends synchronously with the pressure head 14. At the same time as the guide frame 15 descends, it drives the guardrail 33 to move up and down synchronously through the transmission component 4. Thus, during the bending test of the workpiece, the guardrail 33 covers the working area, improving the safety of the device.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
