Description

Technical Field

[0001] This utility model relates to the field of steel pipe compressive strength testing technology, specifically a steel pipe compressive strength testing device. Background Technology

[0002] Steel pipes are steel materials with a hollow cross-section, whose length is much greater than their diameter or circumference. They are classified by cross-sectional shape into circular, square, rectangular, and irregularly shaped steel pipes; and by material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes. Steel pipes have many uses; some are used for media circulation, while others are used for load-bearing support in construction projects. Therefore, after steel pipes are manufactured, their compressive strength needs to be tested to ensure they have good strength and can provide high support strength during load-bearing operations.

[0003] When testing steel pipes, the pipes need to be fixed before being pressed by the testing components. Existing steel pipe pressure testing devices insert both ends of the pipe into holes in extrusion blocks with the same outer diameter as the pipe when fixing it. The pipe ends are fixed by the extrusion blocks. This fixing method is difficult to fix steel pipes of different sizes, thus reducing the flexibility and applicability of the device.

The fixing mechanism is used to fix the steel pipe.

[0008] The testing mechanism is located inside the machine body. The testing mechanism includes a support frame fixedly installed on the top surface of the support plate. A detector and a pressure block are installed below the support frame. The testing mechanism is used to test the pressure of the steel pipe.

[0009] Preferably, the top surface of the support plate has two T-shaped grooves, and T-shaped blocks are slidably installed on the inner walls of the two T-shaped grooves. The top surfaces of the two T-shaped blocks are fixedly connected to the bottom surfaces of the two fixed frames.

[0017] This invention utilizes a motor to rotate a gear, which in turn rotates an arc-shaped rack and a fixed sleeve by a certain angle. The arc-shaped groove on the fixed sleeve rotates, causing an adjusting rod to move. The adjusting rod then moves the clamping blocks. Through the coordinated movement of multiple clamping blocks, multiple clamps can clamp and fix the outer walls of steel pipes of different sizes, making it suitable for the inspection of steel pipes of different sizes, thereby improving the flexibility and adaptability of the device.

[0018] By activating the electric push rod, the fixing frame moves, which in turn moves the fixing sleeve and clamping block. This allows adjustment of the distance between the clamping blocks on both sides, enabling the clamping and fixing of steel pipes of different lengths. Activating the cylinder moves the mounting plate and pressure block. When the pressure block compresses the steel pipe, the reaction force is transmitted to the detector through the pressure block. The data obtained from the detector can accurately determine the compressive strength of the steel pipe, improving the accuracy of the steel pipe compressive strength test.
