DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0023] Embodiment 1, refer to Figures 1 to 5 A metal floor deformation testing device, comprising a first frame body 1, a plurality of table bodies 2 are arranged at the first frame body 1, a plurality of reduction motors 3 are installed at the plurality of table bodies 2, the model of the reduction motor 3 is selected according to actual working requirements, a shell 4 is installed at the output end of the plurality of reduction motors 3, the reduction motor 3 can drive the corresponding shell 4 to rotate, a double-head screw rod 5 is rotatably connected at the plurality of shells 4, a second handle 13 is connected at the plurality of double-head screw rods 5, the second handle 13 can conveniently drive the double-head screw rod 5 to rotate, a plurality of clamping plates 6 are arranged in the plurality of shells 4, the plurality of clamping plates 6 are respectively threadedly connected with the corresponding double-head screw rods 5, the double-head screw rod 5 is used to drive the corresponding clamping plate 6 to adjust the interval, so that the clamping plate 6 can clamp and fix the metal floor, a second frame body 7 is connected at the first frame body 1, a hydraulic cylinder 8 is installed through the second frame body 7, a pressing plate 9 is connected at the output end of the hydraulic cylinder 8, the hydraulic cylinder 8 drives the pressing plate 9 to move downward, so that the metal floor can be pressed and deformed for testing, through the cooperation of clamping by the clamping plate 6, twisting by the reduction motor 3 and pressing downward by the hydraulic cylinder 8, a plurality of composite deformation modes can be applied. This makes the deformation research of the metal floor under complex stress more real and reliable, and the experimental data can better reflect the actual use.

[0024] In this embodiment, the first frame body 1 is connected with multiple groups of screw rods 10, which are respectively connected with the corresponding table bodies 2 through threads. The multiple groups of screw rods 10 are connected with the first handles 11, and the operators can easily control the rotation of the screw rods 10 by rotating the first handles 11, thereby driving the table bodies 2 to move in the horizontal direction. This adjustment method not only can adapt to the testing needs of metal floors of different sizes, but also can flexibly adjust the placement position of the metal floor during the test, ensuring the accuracy and effectiveness of the test. For example, when testing a long metal floor, the table bodies 2 can be appropriately pulled apart to allow the metal floor to be stably placed between the clamping plates 6; for a wider metal floor, the table bodies 2 can be brought together to provide better clamping and support. The first frame body 1 is connected with multiple groups of first sliding rods 12, which are respectively connected with the corresponding table bodies 2 through sliding. The multiple groups of first sliding rods 12 connected with the first frame body 1 are connected with the corresponding table bodies 2 through sliding, providing guidance and support for the movement of the table bodies 2, further improving the stability of the table bodies 2 during adjustment. The first sliding rods 12 can prevent the table bodies 2 from shifting or shaking during movement, ensuring that the table bodies 2 always remain in the correct position. This is crucial for ensuring the relative positional accuracy of the components such as the reduction motor 3, the housing 4, and the clamping plates 6. For example, when testing a metal floor for torsion, if the table bodies 2 are unstable, it may cause uneven stress on the metal floor, affecting the accuracy of the test data. The first frame body 1 is connected with the base 16 at each corner, and the multiple groups of clamping plates 6 are connected with the rubber pads 15. On the one hand, the rubber pads 15 can effectively protect the surface of the metal floor, preventing scratches or indentations caused by direct contact between the clamping plates 6 and the metal floor during clamping. On the other hand, the rubber pads 15 also have good anti-slip performance, which can increase the friction between the clamping plates 6 and the metal floor, preventing the metal floor from slipping during the test due to stress. When performing deformation tests such as torsion or depression, the metal floor needs to withstand a lot of force, and if there is not enough friction, the metal floor may shift between the clamping plates 6, resulting in test failure or inaccurate data. The multiple groups of housings 4 are connected with multiple groups of second sliding rods 14, which are respectively connected with the corresponding clamping plates 6 through sliding, providing precise guidance for the movement of the clamping plates 6 inside the housings 4. When the double-headed screw rod 5 rotates to bring the clamping plates 6 closer or farther apart, the second sliding rods 14 ensure that the clamping plates 6 move smoothly along the predetermined straight line direction, avoiding tilting or jamming of the clamping plates 6. The first frame body 1 is designed in a hollow manner, allowing the metal floor to be twisted and deformed at the hollow part of the first frame body 1.

[0025] The working principle of the embodiment is as follows: in use, first, according to the size and other factors of the actual metal floor, the first handle 11 drives the screw rod 10 to rotate to adjust the placement of the table body 2 outside the first frame body 1; after the position of the table body 2 is changed, the second handle 13 drives the rotation of the double-head screw rod 5 to make the corresponding clamping plates 6 approach each other; a plurality of clamping plates 6 can clamp and fix the metal floor; after the fixing is completed, the two groups of speed reducer motors 3 are reversely rotated correspondingly, so that the metal floor clamped by the clamping plates 6 is twisted; at the same time of the twisting, the hydraulic cylinder 8 drives the pressing plate 9 to press down, and the metal floor can be subjected to a plurality of composite deformation tests.

[0026] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
