Description

Technical Field

[0001] This utility model relates to the technical field of steel structure testing equipment, specifically to a steel structure testing fixture. Background Technology

[0002] Steel structures are widely used in construction, bridges, towers, masts, and shipbuilding due to their high strength, light weight, and fast construction speed. However, during long-term use, steel structures are affected by various factors such as loads, environmental corrosion, and material aging, which may lead to a decline in their mechanical properties and even structural safety hazards. Therefore, regular inspection and performance evaluation of steel structures are crucial.

[0003] Currently, common steel structure testing equipment on the market mainly includes universal testing machines and compression testing machines. Although these devices can perform basic mechanical property tests, they still have the following shortcomings: First, traditional equipment is usually complex in structure and bulky, making it inconvenient for on-site testing and mobile use; second, the clamping systems of existing equipment are often not very targeted, have poor adaptability to steel structure specimens of different shapes and sizes, and changing clamps is cumbersome; third, most devices cannot display pressure values ​​in real time during the pressurization process, requiring reliance on external measuring tools, which is inconvenient to operate and has large errors; in addition, deformation measurement mostly uses traditional mechanical dial indicators or micrometers, the readings are not intuitive, and the data processing efficiency is low.

[0004] Therefore, there is an urgent need to develop a steel structure testing fixture that is simple in structure, easy to operate, has integrated functions, and is suitable for various testing scenarios in laboratories and on-site. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a steel structure inspection fixture to solve the problems of complex structure, single function and inconvenient operation of the existing inspection equipment.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A steel structure inspection fixture, comprising:

[0008] The workbench surface;

[0009] The clamps are detachably mounted on the table, and a pair are provided on the left and right sides in a mirror image.

[0010] The hydraulic cylinder comprises a hydraulic cylinder, a mounting base, a pressure sensor, a digital display, and a pusher block. The cylinder body of the hydraulic cylinder is mounted and fixed on a platform, and a mounting base is fixed to the piston shaft end. A pusher block is connected to the lower side of the mounting base via a pressure sensor. The digital display is electrically connected to the pressure sensor.

[0011] The deformation measurement structure is set on the platform and is used to measure the deformation of the steel structure to be inspected.

[0012] As an improvement, the fixture includes a U-shaped plate, a handle screw, and a pressing plate. When the U-shaped plate is laid down, the handle screw is threaded into a pre-drilled screw hole on the top plate of the U-shaped plate, and the pressing plate is rotatably connected to its end. This fixture can clamp and fix steel structures to be inspected, such as square tubes.

[0013] As an improvement, the clamp also includes an upper clamp, a lower clamp, and a hand-tightening screw; after the upper and lower clamps are fitted together, one end of each is hinged together, and the hand-tightening screw passes through a pre-drilled hole at the other end of the upper clamp and is threaded into a screw hole at the other end of the lower clamp. This allows for the clamping and fixing of steel structures to be inspected, such as round tubes.

[0014] As an improvement, raised cylinders are formed on the bottom surface of the U-shaped plate and the bottom of the lower half of the clamp, respectively. A bolt post thinner than itself is fixed on the bottom surface of the raised cylinder. After passing through a pre-drilled hole on the platform, the bolt post is threaded to a nut located on the underside of the platform. This allows the clamp to be easily installed, removed, and replaced.

[0015] As an improvement, the deformation measurement structure includes a sleeve, a movable column, and a stop plate. The movable column is fitted with a sleeve that is embedded and fixed to the platform, and is frictionally connected to the sleeve. Height measurement scale lines are provided on the side wall of the movable column, and a stop plate is formed at the top, which is attached to the lower side of the steel structure to be tested. This facilitates the measurement of the deformation of the steel structure after it has been compressed and bent.

[0016] It is worth mentioning that the hydraulic cylinder, pressure sensor and digital display in this technical solution are all existing devices in common knowledge, and their use and control methods are all existing technologies (the series circuit of the pressure sensor and digital display also needs to be connected to a PLC control module, etc., so as to form a complete intelligent control circuit).

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. This utility model integrates the clamping mechanism, the pressure application mechanism, and the deformation measurement mechanism onto the same worktable, realizing a unified operation for clamping and fixing steel structure specimens, applying pressure, real-time pressure monitoring, and deformation measurement. This avoids the cumbersome process of using multiple devices and multiple clamping operations required in traditional testing, significantly improving testing efficiency.

[0019] 2. This utility model features a detachable, mirror-symmetric clamp and provides at least two clamping options (U-shaped plate clamping and clamping clamping), allowing for flexible adaptation to steel structure specimens with different cross-sectional shapes (such as square, round, and irregular shapes) and sizes. The clamp is fixed by bolts and nuts, facilitating easy assembly and disassembly and greatly expanding the applicable scenarios of the tooling.

[0020] 3. This utility model features a clear structure, well-defined functions for each module, and a simple and easy-to-understand operating procedure, enabling the completion of most routine testing tasks without the need for specialized personnel. Its relatively low manufacturing cost facilitates its widespread application in laboratories, construction sites, quality inspection stations, and other similar settings, demonstrating high practical value and promising market prospects.

A raised cylinder 13 is formed on the bottom surface of the U-shaped plate 7, and a bolt post 14 thinner than itself is fixed on the bottom surface of the raised cylinder 13. The bolt post 14 passes through a pre-drilled through hole on the platform 1 and is threaded to a nut 15 located on the lower side of the platform 1.
