Description

Technical Field

[0001] This utility model relates to the field of steel structure metal detection technology, and in particular to a steel structure prestress detection device. Background Technology

[0002] In the field of modern engineering construction, steel structures are widely used in various engineering projects such as high-rise buildings, large bridges, and industrial plants due to their advantages such as high strength, light weight, and fast construction speed. The prestress level of steel structures is directly related to the load-bearing capacity, stability, and durability of the structure. Accurate detection of steel structure prestress has become a key link in ensuring project quality and safety. However, current traditional detection methods have revealed many problems and are difficult to meet the growing needs of engineering construction.

[0003] Traditional steel structure prestressing testing devices are mostly fixed in their testing locations, making it difficult to flexibly change them according to the actual testing needs of the steel. Testing other locations on the steel requires cumbersome disassembly and reassembly operations, which increases testing costs and operational difficulty, and seriously affects the assessment of the overall quality of the steel. Therefore, this application designs a steel structure prestressing testing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a prestressed steel structure detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel structure prestress testing device is provided, which includes a workbench, a display installed at one end of the top of the workbench, two support blocks symmetrically fixed to the workbench, a wire feeding box fixed to one side of one support block, a moving component horizontally arranged between the two support blocks, a connecting block provided at the bottom of the moving component, a threaded rod fixed to the bottom of the connecting block, and a detection sensor for detecting the prestress of steel threadedly connected to the threaded rod.

[0007] Preferably, the movable component includes a mounting base installed between two support blocks, a lead screw rotatably mounted inside the mounting base, a motor mounted at one end of the lead screw, and the motor coaxially connected to the lead screw.

[0008] Preferably, a movable block is threaded onto the lead screw, and the movable block is provided with bolts for fixing the connecting block.

[0009] Preferably, the inner sleeve of the detection sensor is provided with a soft sleeve, which is composed of a pair of half soft sleeves joined together. A wiring port is provided on one side of the detection sensor, and a cable is inserted into the wiring port. The other end of the cable is connected to the display.

[0010] Preferably, a fixing plate for fixing steel is provided on one side of another support block, and a retaining sleeve is sleeved inside the fixing plate.

[0011] Preferably, the lead screw is fitted with multiple support frames for supporting the cable, and elastic ropes are interspersed between the multiple support frames.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation between the fixing plate and the clamping sleeve can firmly fix the steel, keeping it stable during the testing process and avoiding shaking and displacement; the cooperation between the detection sensor and the soft sleeve can reduce friction and collision between the detection sensor and the steel, extend its service life, ensure stable operation of the detection sensor, and improve detection accuracy; the setting of the movable component allows the operator to accurately and conveniently adjust the position of the detection sensor according to the steel testing needs, and to test different parts of the steel. This solves the problem of inconvenient adjustment of the detection position and difficulty in testing the entire steel in traditional detection devices, improving testing efficiency and comprehensiveness, and obtaining prestress data of various parts of the steel, providing a basis for a comprehensive evaluation of steel quality.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-4 This utility model provides a steel structure prestress testing device, which includes a workbench 1. A display 2 is installed at one end of the top of the workbench 1. The display 2 allows the operator to obtain the steel structure prestress testing information in real time and accurately, and to keep track of the testing situation in a timely manner. Two support blocks are symmetrically fixed on the workbench 1. A cable box 7 is fixed to one side of one support block. The cable box 7 helps to prevent the cable 6 from being pulled, tangled or damaged during the testing process.

[0021] A movable component is horizontally arranged between the two support blocks. A connecting block 11 is provided at the bottom of the movable component. The connecting block 11 facilitates the effective connection between the detection sensor 12 and the movable block 13. A threaded rod is fixed to the bottom of the connecting block 11. The threaded rod facilitates the adjustment of the position of the detection sensor 12, ensuring that the detection sensor 12 can accurately reach the detection position.

[0022] A detection sensor 12 is threaded onto the threaded rod. The detection sensor 12 facilitates accurate detection of the prestress in the steel, providing an important basis for the quality assessment and safety inspection of the steel structure.

[0023] In this utility model, the movable component includes a mounting base 3 installed between two support blocks. A lead screw 5 is rotatably installed inside the mounting base 3. A motor 4 is installed at one end of the lead screw 5. The motor 4 is coaxially connected to the lead screw 5. The lead screw 5 facilitates precise control of the moving distance and position of the detection sensor 12, ensuring the accuracy and comprehensiveness of the detection.

[0024] A movable block 13 is threaded onto the lead screw 5. The movable block 13 is equipped with bolts for fixing the connecting block 11. The movable block 13 facilitates the adjustment of the position of the detection sensor 12 in the direction of the lead screw 5. A soft sleeve 10 is provided inside the detection sensor 12. The soft sleeve 10 is composed of a pair of half soft sleeves 10 joined together. A wiring port is provided on one side of the detection sensor 12. A cable 6 is inserted into the wiring port. The other end of the cable 6 is connected to the display 2. The soft sleeve 10 helps to extend the service life of the detection sensor 12 and ensure the accuracy and stability of the detection sensor 12.

[0025] Another support block in this scheme has a fixing plate 9 for fixing steel on one side. The fixing plate 9 is fitted with a clamp 8. The fixing plate 9 makes it easier to fix the steel more firmly and reliably, providing a stable test object for the testing work. The lead screw 5 is fitted with multiple support frames for supporting cables 6. Elastic ropes are interspersed between the multiple support frames. The cables 6 make it easy to ensure that the test data can be transmitted accurately and in a timely manner, ensuring the real-time and reliable test results.

[0026] The working principle of this solution is as follows: When in use, the operator first places the steel to be tested into the fixed plate 9, and the clamp 8 is tightly fitted onto the outside of the steel. Through the cooperation between the fixed plate 9 and the clamp 8, the steel is firmly fixed to prevent it from shaking or shifting during subsequent testing.

[0027] Next, the motor 4 is started. The motor 4 serves as a power source, driving the lead screw 5, which is coaxially connected to it, to rotate smoothly within the mounting base 3. Since the lead screw 5 and the moving block 13 are connected by threads, the rotation of the lead screw 5 is converted into the linear movement of the moving block 13 along the lead screw 5. The moving block 13 is fixed to the connecting block 11 by bolts. The bottom of the connecting block 11 is fixed to a threaded rod, and the detection sensor 12 is threadedly connected to the threaded rod.

[0028] Therefore, the movement of the moving block 13 causes the detection sensor 12 to move horizontally. The operator flexibly adjusts the position of the detection sensor 12 according to the detection requirements of the steel to ensure that it can accurately reach the part to be detected. Then, the detection sensor 12 contacts the steel and begins to detect the prestress of the steel structure. The detection sensor 12 converts the detected prestress data into an electrical signal and transmits it to the display 2 through the cable 6. During this process, the cable box 7 orderly stores or releases the cable 6 according to the movement of the detection sensor 12 to prevent the cable 6 from getting tangled.

[0029] Finally, display 2 receives the data from detection sensor 12 and presents it in intuitive numerical and graphical form. The operator reads the data on display 2 and analyzes and evaluates the prestress of the steel structure based on relevant standards and experience to determine whether it meets the quality requirements. At this point, the use of the steel structure prestress detection device is completed.

[0030] 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.
