By setting up the power motor 4, the first threaded rod 5, and the movable door 8, starting the power motor 4 drives the first threaded rod 5 to rotate, indirectly causing the movable door 8 to move, thus opening and closing the movable door 8. This prevents debris from splashing onto workers without affecting the insertion and removal of building steel samples, protecting the safety of workers and improving the safety of the strength testing device.

[0027] A fixing device 11 is provided in the center of the base 1. The fixing device 11 includes a second threaded groove 111, a dual-axis motor 112, a second threaded rod 113, a second bearing 114, a second threaded block 115, a vertical plate 116, a connecting rod 117, and a clamp 118. By setting up the dual-axis motor 112, the second threaded rod 113, and the clamp 118, the clamp 118 is indirectly moved by starting the dual-axis motor 112 to drive the two second threaded rods 113 to rotate, so that the two clamps 118 move closer and further apart, thereby realizing the fixed installation of building steel samples of different sizes and improving the practicality of the strength testing device.

[0028] The protective shell 2 is installed on the upper surface of the base 1. The surface of the sliding door 8 is equipped with a handle 801. The outer ring of the first bearing 6 is fixedly connected to the inside of the first threaded groove 3. The upper surface of the first threaded block 7 is slidably connected to the first threaded groove 3. The sliding door 8 can be manually opened and closed by setting the handle 801, which can also protect the staff when the automatic mechanism fails to work.

[0029] The lower end of the inner casing 2 is provided with a groove 9, and a slider 10 is slidably connected inside the groove 9. The lower end of the first threaded block 7 is fixedly connected to the upper right side of the sliding door 8, and the upper end of the slider 10 is fixedly connected to the lower right side of the sliding door 8. By setting the slider 10 to slide inside the groove 9, the range of motion of the sliding door 8 is limited, preventing the sliding door 8 from shaking up and down during movement, and improving the stability of the sliding door 8 when it is working.

[0030] The inner center of the second threaded groove 111 is fixedly connected to the dual-axis motor 112. The two output shafts of the dual-axis motor 112 are fixedly connected to the second threaded rod 113. The other end of the second threaded rod 113 is fixedly connected to the inner ring of the second bearing 114. The surface of the second threaded rod 113 is threadedly connected to the second threaded block 115. The upper end of the second threaded block 115 is fixedly connected to the upright plate 116. The inner side of the upright plate 116 is fixedly connected to the connecting rod 117. The other end of the connecting rod 117 is fixedly connected to the clamp 118. The second threaded groove 111 is opened at the inner center of the upper end of the base 1. The outer ring of the second bearing 114 is fixedly connected to the second threaded groove 111.

By setting the placement platform 12, the designated position for placing the building steel sample can be located, preventing operator errors, improving operator efficiency, and avoiding danger caused by operator errors. The opening 13 is set to reduce the damage to the placement platform 12 by the strength testing mechanism 18, and is also an important part of enabling the strength testing mechanism 18 to perform strength testing on the building steel sample.

[0032] A column 14 is fixedly connected to the upper end of the base 1, and a top plate 15 is fixedly connected to the upper end of the column 14. A hydraulic press 16 is installed inside the top plate 15. A pressure rod 17 is fixedly connected to the output end of the hydraulic press 16. A strength testing mechanism 18 is installed at the lower end of the pressure rod 17. By starting the hydraulic press 16, the pressure rod 17 is moved downward, causing the strength testing mechanism 18 to move downward and press down on the building steel sample. The pressure sensor installed inside the strength testing mechanism 18 detects the generated pressure and calculates the strength value according to the machine.

[0033] Working principle: When in use, the power is turned on. To protect the safety of the staff, the power motor 4 is started. The output shaft of the power motor 4 drives the first threaded rod 5 to rotate. The surface of the first threaded rod 5 drives the first threaded block 7 to move. The lower end of the first threaded block 7 drives the sliding door 8 to move to the right, so that the sliding door 8 is closed. The debris generated by the strength testing device will be blocked by the protective shell 2 and the sliding door 8, thus protecting the safety of the staff.

[0034] When fixing structural steel samples of different sizes, the dual-axis motor 112 is started. The two output shafts of the dual-axis motor 112 drive the second threaded rod 113 to rotate. The second threaded rod 113 drives the second threaded block 115 to move. The upper end of the second threaded block 115 drives the upright plate 116 to move. The inner side of the upright plate 116 drives the connecting rod 117 to move. The other end of the connecting rod 117 drives the clamp 118 to move, so that the two clamps 118 clamp the structural steel samples of different sizes, thereby fixing the structural steel samples of different sizes.
