[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a steel structure rigidity testing device, including a fixing mechanism 1 and a testing mechanism 2. The fixing mechanism 1 includes a fixing frame 12, a cylinder 15, and a lifting plate 16. The fixing mechanism 1 also includes a movable frame 11, an electric push rod 14, a cylinder 111, a moving plate 112, and a bending rod 114. One end of the electric push rod 14 is fixedly connected to the bottom end of the movable frame 11. Two positioning plates 110 are symmetrically slidably connected to the top of the movable frame 11. The bottom of the moving plate 112 is fixedly connected to the top of the cylinder 111, and gear rods 113 are meshed on both sides of the moving plate 112. A slider 13 is slidably connected to the outer side of the positioning plate 110. One end of the bending rod 114 is connected to the slider 13. The outer side is rotatably connected, and the other end of the bent rod 114 is fixedly connected to the outer side of the gear rod 113. The bottom end of the movable frame 11 is fixedly installed with the bottom end of the cylinder 111. The bottom of the movable frame 11 is slidably installed with the bottom end of the fixed frame 12. One end of the electric push rod 14 is fixedly installed with the bottom end of the fixed frame 12. Both ends of the lifting plate 16 are slidably connected with the top of the fixed frame 12. The top of the cylinder 15 is fixedly connected with the bottom of the lifting plate 16, and the bottom end of the cylinder 15 is fixedly connected with the bottom end of the fixed frame 12. A pressure plate 17 is provided on the top of the lifting plate 16, and multiple springs 18 are provided between the top of the pressure plate 17 and the lifting plate 16. A rubber pad 19 is fixedly connected to the bottom of the pressure plate 17.

[0025] The specific settings and functions of this embodiment are described in detail below: The controller activates cylinder 15, which moves the lifting plate 16 and pressure plate 17 downwards until the pressure plate 17 presses down on one end of the steel structure. A spring 18 is installed at the top of the pressure plate 17, and the bottom of the pressure plate 17 contacts the surface of the steel structure via a rubber pad 19. This ensures that the pressure plate 17 can press down on the steel structure without causing damage. Simultaneously, based on the length of the steel structure, the controller activates electric push rod 14, which moves the movable frame 11 along the bottom of the fixed frame 12 until the positioning plate 110 moves to the positions on both sides of one end of the steel structure. At this point, the controller activates cylinder 111, which moves the moving plate 112 downwards. This causes the two gear rods 113 to rotate, thereby causing the two positioning plates 110 to move towards each other along the top of the movable frame 11 (when the cylinder 111 drives the moving plate 112 to move downward, the two gear rods 113 rotate, and the two positioning plates 110 move towards each other along the top of the movable frame 11; conversely, when the cylinder 111 drives the moving plate 112 to move upward, the two positioning plates 110 move away from each other along the top of the movable frame 11. By driving the moving plate 112 up and down through the cylinder 111, the two positioning plates 110 can move in opposite directions). The two positioning plates 110 clamp one end of the steel structure, thereby firmly fixing the steel structure at the top of the fixed frame 12, ensuring that the steel structure will not loosen or shift during the entire inspection process.

[0026] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, the detection mechanism 2 includes a fixed frame 21, an adjusting motor 22, a drive gear 24, and a connecting belt 25. One side of the fixed frame 21 is fixedly installed on one side of the movable frame 11. A gear ring 23 is provided inside the fixed frame 21. The outer walls of the gear ring 23 and the drive gear 24 mesh with the inner wall of the connecting belt 25. Two vertical plates 26 are slidably connected to both ends of the fixed frame 21, and two horizontal plates 27 are slidably connected to the other two ends of the fixed frame 21. A laser displacement sensor 28 is fixedly connected to one end of the vertical plate 26, and a laser displacement sensor 29 is fixedly connected to one end of the horizontal plate 27. The inner sides of the horizontal plate 27 and the vertical plate 26 mesh with the outer wall of the gear ring 23. The output end of the adjusting motor 22 is fixedly connected to one end of the drive gear 24, and the bottom end of the adjusting motor 22 is fixedly installed on the outer side of the fixed frame 21.

[0027] The overall effect of this embodiment is that by setting up multiple multi-directional sensors around the steel structure, the device can comprehensively detect steel structures of different sizes. At the same time, whether it is a planar structure or a complex spatial structure, it can achieve all-round displacement and strain monitoring, fully reflecting the overall rigidity of the steel structure, avoiding the drawbacks of missing problems in local detection, and meeting the rapid detection needs in construction projects.

[0028] The method of use and working principle of this device: The steel structure to be tested is transported to the testing platform (the top position of the fixed frame 12). One end of the steel structure is placed at the bottom position of the pressure plate 17. The controller opens cylinder 15, which drives the lifting plate 16 and the pressure plate 17 to move downward until the pressure plate 17 presses one end of the steel structure. At the same time, according to the length of the steel structure, the controller opens electric push rod 14, which drives the movable frame 11 to slide along the bottom of the fixed frame 12 until the positioning plate 110 moves to the positions on both sides of one end of the steel structure. At this time, the controller opens cylinder 2 111, which drives the movable plate 112 to move downward, so that the two positioning plates 110 move towards each other along the top of the movable frame 11. The two positioning plates 110 clamp one end of the steel structure, and the steel structure is firmly fixed at the top position of the fixed frame 12.

[0029] After the steel structure is fixed, the operator turns on the adjusting motor 22 via the controller. The adjusting motor 22 drives the drive gear 24 to rotate, and the drive gear 24 drives the gear ring 23 to rotate via the connecting belt 25, thereby moving the two vertical plates 26 and the two horizontal plates 27. Figure 4 and Figure 5 As shown, when the gear ring 23 rotates, the two vertical plates 26 and the two horizontal plates 27 move in opposite directions. By controlling the rotation direction of the gear ring 23, the two vertical plates 26 and the two horizontal plates 27 move towards each other, thereby causing the two laser displacement sensors 1 28 and the two laser displacement sensors 29 to simultaneously approach the steel structure in the four directions of up, down, left, and right.

[0030] Based on the type of steel structure, design load, and other relevant information, the operator sets the loading parameters and data acquisition parameters, starts the loading system, and applies the load to the steel structure according to the set loading scheme. At the same time, two laser displacement sensors 28 and 29 emit laser beams and receive reflected light to accurately measure the displacement changes at various points of the steel structure during the loading process. The sensors have the characteristics of high resolution and fast response, and can capture minute displacement fluctuations in real time. The measurement accuracy can reach the micrometer level. Laser displacement sensors 28 and 29 transmit the detection data to the control system in real time. The control system uses built-in algorithms to process and analyze the data, and judges whether the rigidity of the steel structure meets the requirements according to the preset evaluation criteria, generating a detailed inspection report. The operator can intuitively view the data of each measurement point and the overall rigidity evaluation results of the steel structure.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
