[0029] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0030] Referring to the attached Figure 1 - attached Figure 6 , a prestress testing device for ferrous metal smelting and rolling products provided by the present utility model includes:

[0031] A test seat 1, with a cavity one opened inside the test seat 1;

[0034] A servo motor 15 is fixedly connected to the bottom of the cavity 1, and the output shaft of the servo motor 15 is fixedly connected to a rotating shaft 16, and a driving component is provided between the rotating shaft 16 and the rotating block 5;

[0035] The driving assembly includes a bevel gear 17 and a bevel gear 2 18 that are meshed and connected. The bevel gear 17 is fixedly connected to one end of the rotating shaft 16. The bevel gear 2 18 is fixedly sleeved on the outside of the bottom end of the rotating block 5. A display screen 22 is fixedly connected to the front side of the test seat 1. The pressure sensor 13 is electrically connected to the display screen 22.

[0036] In this embodiment, the operation of the servo motor 15 can make the electric push rod 11, the pressure sensor 13, the pressure block 14 and other components move in turn to the top of the two U-shaped frames 3 and perform prestress testing on the steel structure 4. When testing the steel structure 4 on one station, the tested one on another station can be manually removed and replaced with a new one. In this way, the testing work can be carried out while the steel structure 4 is replaced. Such a cycle can avoid the device being in a standby state for a long time, thereby increasing the efficiency of the test.

[0037] Among them, in order to achieve the purpose of preventing the steel structure 4 from being broken out of the device during the test, the device is implemented by the following technical solutions: the fixing assembly includes two L-shaped plates 19, the two L-shaped plates 19 are respectively fixedly connected to the front and rear sides of the U-shaped frame 3, the two L-shaped plates 19 are both fixedly embedded with electric push rods 20, the inner ends of the two electric push rods 20 are both fixedly connected with sleeves 21, and the two sleeves 21 are respectively sleeved on the outside of the two ends of the steel structure 4, and the fixing assembly can clamp and fix the steel structure 4, so as to prevent the steel structure 4 from being broken out of the device during the test;

[0038] Among them, in order to achieve the purpose of preventing the slider 9 from being damaged due to an upward thrust during testing, the following technical solution is adopted in this device: A bracket 23 is fixedly connected between the slider 9 and the moving block 10. A U-shaped bracket three 24 is fixedly connected to the U-shaped bracket two 7. The bracket 23 is in contact with the inner wall of the top of the U-shaped bracket three 24, and the bracket 23 is slidably connected to the U-shaped bracket three 24. The designs of the bracket 23 and the U-shaped bracket three 24 can prevent the slider 9 from being damaged due to an upward thrust during testing;

[0039] Among them, in order to achieve the purpose of reducing wear, the following technical solution is adopted in this device: The rotating block 5 is connected to both the test bench 2 and the test seat 1 through bearings, and the connection through bearings can reduce wear.

[0040] The usage process of this utility model is as follows: When a prestress test needs to be carried out on the steel structure part 4, place the steel structure part 4 on both of the U-shaped brackets one 3, and then control the two electric push rods two 20 on one of the U-shaped brackets one 3 to work. In this way, the two sleeves 21 can be sleeved on the outer sides of both ends of the steel structure part 4 and clamp and fix it. Then, control the two electric push rods one 11 on the other U-shaped bracket one 3 to work for the clamping and fixing work based on the same principle;

[0041] After the fixation is completed, control the electric push rod two 20 to work. In this way, the fixed block 12, the pressure sensor 13, and the pressing block 14 can move downward. When the pressing block 14 contacts the steel structure part 4, continue to control the electric push rod two 20 to make the pressing block 14 move downward to apply pressure to the steel structure part 4. Since the pressure sensor 13 is electrically connected to the display screen 22, when applying pressure, the pressure sensor 13 can feed back the pressure applied by the pressing block 14 to the display screen 22 for display, so as to facilitate intuitively observing the value of the prestress borne by this position of the steel structure part 4, and then complete the prestress test. When it is necessary to carry out a prestress test on other positions of the steel structure part 4, control the electric slide rail 8 to work. In this way, the slider 9 can move back and forth, so that the moving block 10, the electric push rod one 11, the fixed block 12, the pressure sensor 13, and the pressing block 14 can move back and forth. In this way, the pressing block 14 can move directly above other positions of the steel structure part 4, and then the test work can be carried out again based on the same principle;

[0042] After the steel structure part 4 on a work station is tested, control the servo motor 15 to work. The work of the servo motor 15 drives the rotation of the first rotating shaft 16. The rotation of the first rotating shaft 16 drives the rotation of the first bevel gear 17. The rotation of the first bevel gear 17 drives the rotation of the second bevel gear 18. The rotation of the second bevel gear 18 drives the rotation of the rotating block 5. In this way, the connecting block 6, the second U-shaped frame 7 and the components on the second U-shaped frame 7 can be rotated. Control the servo motor 15 to make the rotating block 5 rotate half a circle. In this way, components such as the pressing block 14 can be moved to directly above another work station. Then, by the same principle, the prestress test work can be carried out on the steel structure part 4 on this work station. At this time, the operator can remove the tested one on another work station and place a new one. In this way, it can be realized that while replacing the steel structure part 4, the testing work is carried out at the same time. By circulating in this way, the device can be prevented from being in a standby waiting state for a long time, thereby increasing the testing efficiency.

[0043] The above are only the preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention shall fall within the scope of protection required by the present invention.
