[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This square steel pressure testing device involves placing the square steel on pressure sensors on an upper connecting frame. Two sets of pressure sensors are positioned opposite each other, and anti-slip pads are installed on the sensors to prevent the square steel from sliding or shifting. The hydraulic cylinder on the connecting frame moves its hydraulic telescopic rod axially up and down. During testing, the hydraulic telescopic rod moves downwards and is fixed to the upper pressure plate by a mounting plate. This causes the upper pressure plate to move downwards and test the pressure on the square steel on the pressure sensor. This device allows for the placement of square steel of different specifications on the pressure sensor for pressure testing. The data is saved and transmitted through the pressure sensor. The sensor has markings on the edge of the pressure plate to facilitate observation of the pressure rise and fall, thereby judging the deformation. There are protective plates on both sides of the pressure sensor to assist in positioning the square steel. After the test is completed, the first electric push rod in the bearing groove in the middle of the fixed frame moves the first push rod axially. After the test is completed, the first push rod retracts inward to pull the docking blocks in the two connecting frames out of the docking groove and form a gap in the middle. The square steel is then placed on the roller line inside the main body of the equipment below and moved to facilitate the testing of square steel of different specifications, improve the testing efficiency, and enhance the practicality of the equipment. 2. This square steel pressure testing device is easily moved by the casters located under the two sets of support columns on both sides of the lower middle part of the main body. After moving to the designated position, the second electric push rod under the support columns on both sides of the main body of the device is opened and activated. The second push rod moves up and down axially. Moving the second push rod downward and placing the pad on the ground increases the stability of the device. When placing the square steel on the roller line, the second push rod on one side can be moved downward and raised to the position of that side, while the position of the other side is lowered, causing the main body of the device to tilt downward and the square steel to be conveyed downward to one side until it is transferred to the ground, facilitating the collection of the square steel after pressure testing.

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.

[0017] Please see Figure 1 - Figure 4This utility model provides a technical solution: a square steel pressure testing device, including a main body 1, roller lines 2 evenly distributed on the inner side of the main body 1, a fixed frame 3 set in the middle of the left and right sides above the main body 1, and the fixed frames 3 are positioned opposite each other, a bearing groove 4 is opened in the middle of the fixed frame 3, a first electric push rod 5 is evenly distributed on the inner side of the bearing groove 4, a first push rod 6 is set on the right side of the first electric push rod 5, a connecting frame 7 is set on the right side of the first push rod 6, and there are two sets of connecting frames 7, a hydraulic cylinder 8 is evenly distributed on the left side above the connecting frame 7, and a hydraulic telescopic rod 9 is set above the hydraulic cylinder 8.

[0018] A mounting plate 10 is provided above the hydraulic telescopic rod 9. An upper pressure plate 11 is provided in the middle of the right side of the mounting plate 10. A pressure sensor 12 is provided in the middle of the right side above the connecting frame 7. An anti-slip pad is provided on the pressure sensor 12. A protective plate 13 is provided on the left side of the pressure sensor 12. A docking groove 14 is provided on both sides of the right edge of the connecting frame 7. A docking block 15 is provided on both sides of the left edge of the connecting frame 7. The left side of the connecting frame 7 is the docking groove 14 and the other side is the docking block 15. The docking block 15 is slidably connected to the inside of the docking groove 14, and the docking block 15 and the docking groove 14 are opposite each other.

[0019] The lower part of the main body 1 of the equipment has four sets of connecting support legs 16, two in the middle and two on the left and right sides. The lower part of the inner side of the support legs 16 is provided with a connecting support rod 17. The lower part of the support legs 16 is provided with a second electric push rod 18. The lower part of the second electric push rod 18 is provided with a second push rod 19. The lower part of the second push rod 19 is provided with a pad 20. The lower part of the support legs 16 on the two sides of the lower middle part of the main body 1 of the equipment is provided with casters 21. The lower part of the support legs 16 on the left and right sides of the lower part of the main body 1 of the equipment is provided with a second electric push rod 18. The lower part of the support legs 16 on the two sides of the lower middle part of the equipment is provided with casters 21.

[0020] Working principle: When the square steel pressure testing device is needed, the casters 21 located under the two sets of support columns 16 on the lower sides of the middle of the main body 1 facilitate the movement of the device. The support columns 16 are connected by connecting support rods 17 to increase stability. After moving to the designated position, the second electric push rods 18 located under the support columns 16 on the left and right sides of the lower part of the main body 1 are opened and activated, causing the second push rod 19 to move axially up and down. Moving the second push rod 19 downwards and placing the pads 20 on the ground increases the stability of the device. The device is then secured by the fixed supports on the left and right sides of the middle of the main body 1. The operation of the first electric push rod 5 in the bearing groove 4 opened in the middle of the inner side of the frame 3 causes its first push rod 6 to move axially and extend outward, pushing it to connect the two connecting frames 7. By inserting the connecting block 15 on one side into the connecting groove 14 on the other side, the two connecting frames 7 are fixed. There is a support structure under the connecting frame 7, which makes it more stable and secure during position pressure testing. The square steel is placed on the pressure sensor 12 on the two connecting frames 7. There are two sets of pressure sensors 12, one on the left and one on the right side of the two connecting frames 7 respectively. The pressure sensor 12 is equipped with anti-slip pads to prevent the square steel from sliding and shifting. The hydraulic cylinder 8 on the connecting frame 7 is operated to make the hydraulic pressure... The telescopic rod 9 moves vertically along its axis. During testing, the hydraulic telescopic rod 9 moves downward and is fixed to its upper pressure plate 11 by the mounting plate 10. The upper pressure plate 11 then moves downward to detect the pressure on the square steel on the pressure sensor 12. The pressure sensor 12 stores and transmits the data. The pressure sensor 12 has markings on its lower pressure plate side and can drop a certain height during pressing, making it easy to observe the lifting height and thus determine the deformation of the square steel. Protective plates 13 on both sides of the pressure sensor 12 assist in positioning the square steel. After testing, the load is transferred through the bearing groove 4 in the middle of the fixing frame 3. The operation of an electric push rod 5 causes its first push rod 6 to extend and retract axially. After the test is completed, the first push rod 6 retracts inward, causing the connecting blocks 15 in the two connecting frames 7 to be pulled out of the connecting grooves 14, forming a gap in the middle. The square steel is then placed on the roller line 2 inside the lower equipment body 1. The square steel is moved, and when it is placed on the roller line 2, the second push rod 19 on one side can be moved downward and raised to the position of one side, while the position of the other side is lowered, causing the equipment body 1 to tilt downward and the square steel to be conveyed downward to one side until it is transported to the ground. This makes it easier to collect the square steel after the test, and reduces manual labor.
