Description

Technical Field

[0001] This utility model relates to the technical field of steel structure testing equipment, and in particular to a steel structure stress testing structure. Background Technology

[0002] Stress testing of steel structures is essential for evaluating the quality of steel structure engineering projects or assessing the performance of steel structures to ensure their safety and stability. To determine the actual stress in in-service steel structure components and verify the correctness and reliability of design calculations, stress testing of structural components, especially critical ones, is extremely important. Therefore, regularly conducting stress testing on steel structures and comparing and analyzing the advantages and disadvantages of various stress testing methods can lay a theoretical foundation for better real-time stress testing of steel structure components. Methods for detecting the working stress of steel structural components can be summarized as destructive stress testing methods, non-destructive stress testing methods, and magnetic coupling stress testing methods for steel materials.

[0003] The commonly used non-destructive stress testing methods in the present technology infer the internal stress state of an object by measuring the stress distribution on the object's surface without damaging it. Most of these methods employ ultrasonic testing. Existing stress testing structures capable of ultrasonic testing of steel structures are mostly equipped with clamping and positioning structures to maintain the stability of the steel structure. However, these clamping and positioning structures can usually only clamp one steel structure at a time. If there are many steel structures to be tested (such as steel bars or reinforcing bars), the testing operation takes a long time, reducing testing efficiency. Utility Model Content

[0004] To address the aforementioned issues, this application provides a steel structure stress detection structure.

[0005] To achieve the above objectives, this application provides the following technical solution: a steel structure stress detection structure, including a support base and an ultrasonic probe disposed above the support base. The support base is provided with multiple connecting rods capable of supporting multiple steel structures. The connecting rods are provided with two sets of openable and closable clamping units. Each clamping unit includes a clamping positioning plate one and a clamping positioning plate two distributed in parallel.

[0006] It also includes multiple limit supports that can be raised and lowered. The limit supports are all located at the gaps between multiple connecting rods. Each limit support has multiple limit grooves that can accommodate the insertion of steel structures. The limit grooves are evenly spaced. As the limit support rises, the steel structure falls into the limit groove.

[0007] Furthermore, two bidirectional screws are provided below the connecting rod, and the legs of the clamping positioning plate one and clamping positioning plate two in each clamping unit extend to the bottom of the connecting rod. The legs of the clamping positioning plate one and clamping positioning plate two are respectively installed at the forward and reverse threads of the bidirectional screws.

[0008] Below the connecting rod are two guide rods that are parallel to it, and the legs of the clamping positioning plate one and the clamping positioning plate two are both sleeved on the guide rods.

[0009] Furthermore, both ends of the bidirectional screw are mounted on a support base, and a drive motor capable of controlling the rotation of the bidirectional screw is provided outside the support base.

[0010] Furthermore, the bottom ends of the multiple limiting supports are connected by connecting plates, which are located inside the support base. The support base is equipped with a drive cylinder that can control the raising and lowering of the connecting plates.

[0011] The support base is provided with multiple guide rods, all of which pass through the connecting plate. When the connecting plate moves, the limiting support moves along the distribution direction of the guide rods.

[0012] Furthermore, the ultrasonic probe is equipped with a traction arm, which has an i-shaped structure, and each of the two symmetrical support legs of the traction arm is equipped with a follower slider, and each of the two ends of the follower slider is equipped with a roller.

[0013] Each support base is equipped with a positioning support, and each positioning support has a guide channel for accommodating the sliding block. Both the roller and the sliding block can move synchronously with the movement of the traction arm.

[0014] Furthermore, each of the follower sliders is provided with a threaded portion, and each of the threaded portions is provided with an intercepting ring, which is pressed against the surface of the positioning support.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] This invention enables stress testing of multiple steel structures. It allows for simultaneous clamping of multiple steel structures, improving their stability and testing efficiency. During the sequential loading of multiple steel structures, the structures are arranged in an orderly manner, enhancing their stability. The equal spacing between the steel structures effectively avoids incomplete testing and result deviations caused by their close contact with each other. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Example: Reference Figure 1-5 The steel structure stress testing structure shown includes a support base 1 and an ultrasonic probe 13 disposed above the support base 1. The support base 1 contains multiple connecting rods 2 capable of supporting multiple steel structures. Each connecting rod 2 has two sets of openable and closable clamping units. Each clamping unit includes parallel clamping positioning plates 3 and 4. It also includes multiple lifting and lowering limiting supports 8, all located at the gaps between the connecting rods 2. Each limiting support 8 has multiple limiting grooves 81 equidistantly arranged to accommodate the steel structure.

[0026] When performing non-destructive stress testing on multiple steel structures, each steel structure to be tested can be placed one by one on the connecting rod 2. The limiting support 8 ensures that the steel structure falls into the limiting groove 81, effectively preventing shaking or displacement of the already loaded steel structure. This allows multiple steel structures to be arranged in an orderly manner, facilitating orderly loading and improving the stability of the steel structures during the loading process. Furthermore, after the loading operation is completed, the spacing between the multiple steel structures is equal, effectively preventing incomplete testing and deviations in test results caused by multiple steel structures sticking together.

[0027] During the stress testing operation, clamping positioning plate 3 and clamping positioning plate 4 can simultaneously clamp multiple steel structures, further improving the stability of the steel structures. When the ultrasonic probe 13 moves, prestress testing can be performed on multiple steel structures simultaneously, improving testing efficiency.

[0028] Below the connecting rod 2 are two bidirectional screws 5 arranged parallel to it. The legs of the clamping positioning plate 1 3 and clamping positioning plate 2 4 in each clamping unit extend to the bottom of the connecting rod 2. The legs of the clamping positioning plate 1 3 and clamping positioning plate 2 4 are respectively installed at the forward and reverse threads of the bidirectional screws 5. When the bidirectional screws 5 rotate, they can...

[0029] To prevent the clamping positioning plates 3 and 4 from shifting or wobbling during opening and closing, two guide rods 7 are provided parallel to the connecting rod 2 below it. The legs of the clamping positioning plates 3 and 4 are fitted onto the guide rods 7. When the bidirectional screw 5 rotates, causing the clamping positioning plates 3 and 4 to open and close, they move linearly along the distribution direction of the guide rods 7.

[0030] like Figure 2 , Figure 3 As shown, in order to maintain the stability of the bidirectional screw, both ends of the bidirectional screw 5 are mounted on the support base 1. At the same time, a drive motor 6 that can control the rotation of the bidirectional screw 5 is provided outside the support base 1 to provide a power source for the operation of the bidirectional screw 5.

[0031] like Figure 4As shown, the bottom ends of multiple limiting supports 8 are connected by connecting plates 9, which are located inside the support base 1. The support base 1 is equipped with a drive cylinder 10 that controls the lifting and lowering of the connecting plates 9. The operation of the drive cylinder 10 causes the connecting plates 9 and the multiple limiting supports 8 connected to them to rise synchronously until the steel structure falls into the limiting groove 81. To maintain the straightness of the movement of the connecting plates 9 and the limiting supports 8, the support base 1 is equipped with multiple guide rods 11, which all pass through the connecting plates 9. When the connecting plates 9 move, the limiting supports 8 move along the distribution direction of the guide rods 11, thereby ensuring the accuracy of the connection between the limiting groove 81 and the steel structure.

[0032] like Figure 3 As shown, the ultrasonic probe 13 is equipped with a traction arm 12, which has a U-shaped structure. Each of the two symmetrical support legs of the traction arm 12 has a follower slider 14 at its bottom end, and rollers are provided at both ends of the follower slider 14. Each support base 1 is equipped with a positioning support 15, and each positioning support 15 has a guide channel 16 for the follower slider 14 to pass through. When the ultrasonic probe 13 moves to simultaneously perform non-destructive stress testing on multiple steel structures, the traction arm 12 can move synchronously, and the rollers and follower sliders 14 can move synchronously with the movement of the traction arm 12, improving the smoothness and stability of the ultrasonic probe 13 during movement.

[0033] like Figure 3 As shown, in order to maintain the stability of the follower slider 14 inside the guide channel 16, each follower slider 14 is provided with a threaded portion 17, and each threaded portion 17 is provided with an intercepting ring 18, which is pressed against the surface of the positioning support 15. The combination of the intercepting ring 18 and the threaded portion 17 can prevent the follower slider 14 and the traction arm 12 connected to it from shaking, further ensuring the stability of the ultrasonic probe 13 and the traction arm 12 during movement.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
