[0019] Embodiment: As Figures 1 - 4A strength test protection and monitoring device shown in the figure includes a monitoring component 21. The monitoring component 21 includes a profile frame 4. A universal wheel 1 is rotatably installed at the bottom of the profile frame 4. A second baffle 9 is installed at the upper end of the profile frame 4. A third baffle 10 and a fourth baffle 13 are fixedly installed on the side surface of the profile frame 4. A fifth baffle 14 is fixedly installed on the back surface of the profile frame 4. The front end face of the profile frame 4 is set as an inlet / outlet 20. A first baffle 6 is installed at the height position of the inlet / outlet 20 of the profile frame 4. A universal support 11 is fixedly installed on the third baffle 10. A camera 12 is fixedly installed on the universal support 11. The load sensor 16 can adjust its position on the profile frame 4. The profile frame 4 is spliced by profiles of various specific sizes. There is a non-interference space for movement at the bottom and side of the profile frame 4, that is, no profiles are installed below the inlet / outlet 20. The universal wheel 1 should be as short as possible, so as to increase the protection area. The second baffle 9 is fixed to the top of the profile frame 4 with fasteners. The third baffle 10, the fourth baffle 13, and the fifth baffle 14 are respectively fixed to the side surface of the profile frame 4 with fasteners. The second baffle 9, the third baffle 10, the fourth baffle 13, and the fifth baffle 14 are all made of transparent PC endurance plate material, so as to ensure the transparency and strength of the baffles. The height position of the first baffle 6 can be adjusted. Without interfering with the load sensor 16, it can prevent the fragments generated during the test from hurting people to the greatest extent.

[0020] The profile splicing joints of the profile frame 4 are fixedly connected by corner codes 3.

[0021] Connecting plates 2 are fixedly connected to the four corners at the bottom of the profile frame 4 with fasteners. The universal wheel 1 is fixed to the connecting plate 2 with fasteners.

[0022] A plurality of handles 7 are provided on the first baffle 6, the third baffle 10, and the fourth baffle 13. The handles 7 are fixed to the third baffle 10 and the fourth baffle 13 with fasteners. A plurality of handles 7 are provided on the first baffle 6, the third baffle 10, and the fourth baffle 13 to maximize the fixed position of the universal support 11 and ensure that the camera 12 at the end of the universal support 11 can photograph the position to be tested.

[0023] Studs 5 are fixed at intervals on the profiles on both sides of the inlet / outlet 20. Cuts adapted to the studs 5 are opened on both sides of the first baffle 6. A number of studs 5 can make the first baffle 6 height-adjustable in the vertical direction. The first baffle 6 is placed on the studs 5 through the cuts, and a nut each is installed on the corresponding studs 5 on the upper and lower sides of the first baffle 6 to prevent the first baffle 6 from falling off. Handles 7 are also installed at the corresponding positions of the first baffle 6. The material of the first baffle 6 is also selected as transparent PC endurance plate.

[0024] There is a test platform 18 at the lower end of the monitoring component 21. The monitoring component 21 moves on the test platform 18. A test specimen 15 is fixedly installed on the test platform 18. The universal support 11 is fixed on the corresponding handle 7 for convenient observation of the test specimen 15. A camera 12 is installed at the end of the universal support 11. The camera 12 is connected to the test computer through a USB interface to monitor the test state of the test specimen. In case of special circumstances, the test can be stopped immediately, and videos can be recorded if necessary.

[0025] The wheel width of the universal wheel 1 should be greater than the width of the groove 19 on the test platform 18 to prevent the universal wheel 1 from getting stuck in the groove 19 during movement.

[0026] A test specimen 15 and a loading device 17 are respectively and fixedly installed on the test platform 18. The load sensor 16 is connected in series with the test specimen 15 and the loading device 17 through a rod or the like. Before the test, manually move the monitoring component 21 until it covers the test specimen 15. Do not lock the universal wheel 1 before, during, and after the test. Do not install the first baffle 6 during the movement of the monitoring component 21. After moving the strength test protection monitoring device 21 to a suitable position, install the first baffle 6 and fix it slightly with a nut 8. The position of the first baffle 6 in the vertical direction needs to be adjusted according to the height of the load sensor 16 to ensure that the load sensor 16 will not hit the first baffle 6 during the test, and at the same time ensure that the first baffle 6 is as low as possible. Several specifications of the first baffle 6 can be prepared to ensure the maximum applicability. After installing the first baffle 6, fix the universal support 11 with the camera 12 on the corresponding handle 7 and adjust the focal length of the camera 12 for the test specimen 15 to ensure the observation clarity. The loading device 17 is provided with a hydraulic cylinder. The test specimen 15 is pushed and pulled by the hydraulic cylinder of the loading device 17, and the test specimen 15 is also connected to the load sensor, so as to judge the maximum load that the test specimen can bear. During the test, the tester can observe the state of the test specimen on the test computer at the same time. In case of special circumstances, the test can be stopped immediately, and videos can be recorded if necessary. After the test, the fragments generated by the test specimen 15 can be blocked inside by the monitoring component 21 and will not fly out and hurt people. After the test is completed, remove the universal support 11 from the strong monitoring component 21, remove the first baffle 6, and manually move the remaining part of the monitoring component 21 away from the test specimen 15 without interfering with the replacement of the test specimen 15. After the replacement of the test specimen 15 is completed, move the monitoring component 21 to the position covering the test specimen 15, and then install the universal support 11 with the camera 12 and the first baffle 6.
