[0025] like Figures 1-5As shown, this utility model provides a device for testing the safety performance of a building's main structure. It includes a movable base 1 and a pusher mechanism. The movable base 1 allows the device to stand against a wall for testing. The lower surface of the movable base 1 has wheels with braking functions. A cylinder 2 is fixedly connected to the upper surface of the movable base 1. The cylinder 2 pushes the housing 4, controlling the intelligent rebound meter 7 to be at different heights for testing different positions on the wall. The telescopic rod of the cylinder 2 is fixedly connected to a fixing block 3. A sliding groove is provided on the upper surface of the fixing block 3, and a slider is slidably connected within the groove. An electric push rod is installed within the groove to push the slider. The housing 4 and the intelligent rebound meter 7 can slide back and forth on the fixed base 13, facilitating the intelligent rebound meter 7 to move closer to the wall for testing and to change its position further away. The upper surface of the slider is fixedly connected to the housing 4. A first square through-slot is provided on one side of the housing 4, and a sliding plate 5 is vertically slidably connected within the first square through-slot. The sliding plate 5 can slide up and down, allowing the intelligent rebound meter 7 to be at different heights for testing. A second square through slot is provided, within which a sliding seat 6 is slidably connected. The sliding seat 6 can move laterally on the sliding plate 5, performing multiple tests at the same height. Then, by adjusting the height of the sliding plate 5, tests are performed at different heights. An intelligent rebound spring 7 is installed on one side of the sliding seat 6. A multi-point limiting component 8 is provided on one side of the sliding plate 5, limiting the sliding seat 6 at four points. The distance between adjacent limiting points is the same, matching the required spacing for testing. At the limiting points, the sliding seat 6 stops, and the intelligent rebound spring 7 tests the wall. A multi-height limiting component 9 is provided on one side of the housing 4, limiting the height of the sliding plate 5 so that the sliding plate 5 can be at four heights and remain stationary. The distance between the four heights is the same as the distance between the four horizontal points. Four horizontal points are tested at each height, and the difference between two adjacent heights matches the required spacing for testing. This achieves equidistant sixteen-point testing of a rectangular area of ​​the wall, eliminating the need for staff to pre-draw a grid diagram of the rectangular area to be tested, making it more convenient.

[0026] like Figure 3 , Figure 4 as well as Figure 5 As shown, two mounting plates 10 are fixedly connected to one side of the sliding plate 5. A first servo motor 11 is mounted on one side of one of the mounting plates 10. The main shaft of the first servo motor 11 is fixedly connected to the first screw 12. A fixed seat 13 is mounted on one side of the sliding seat 6. The first screw 12 passes through the fixed seat 13 and is threadedly connected to the fixed seat 13. The sliding seat 6 drives the intelligent rebound device 7 to move laterally through the first servo motor 11 driving the first screw 12. This eliminates the need for manual operation by staff and is more convenient.

[0027] like Figure 3 and Figure 4As shown, the multi-point limiting component 8 includes a second servo motor 81, which is fixedly connected to one of the mounting plates 10. The main shaft of the second servo motor 81 is fixedly connected to a round rod 82. Four fixed cylinders 83 are fixedly connected to the outer side of the round rod 82. The four fixed cylinders 83 are arranged in an array, and the spacing between the fixed cylinders 83 is the same as the required detection spacing. A locking block 84 is slidably connected inside the fixed cylinder 83. A spring 22 is fixedly connected between the locking block 84 and the fixed cylinder 83. The sliding seat 6 is provided with a slot, and both sides of the sliding seat 6 are provided with arc surfaces. Both sides of the locking block 84 are also provided with arc surfaces. During the process of the sliding seat 6 driving the intelligent rebound device 7 to move, the contact... When the contact block 84 slides into the fixed cylinder 83 to avoid it, the spring 22 pushes the contact block 84 into the slot, stopping the sliding seat 6. After stopping, the intelligent rebound device 7 detects the wall. After the detection is completed, the second servo motor 81 drives the round rod 82 to rotate, causing the contact block 84 to rotate out of the slot. The first servo motor 11 drives the sliding seat 6 to move. After leaving the contact block 84, the second servo motor 81 drives the round rod 82 to rotate, causing the contact block 84 to reset. Waiting for the second contact block 84 to lock the sliding seat 6, the detection is carried out again. The detection is carried out once at each contact block 84 to control the detection interval and improve the detection accuracy.

[0028] like Figure 3 and Figure 4 As shown, the interior of the housing 4 has fixed posts 14 on both sides of the first square through slot. One side of the fixed post 14 has a square through slot, and a lifting block 15 is slidably connected in the square through slot. The lifting block 15 is fixedly connected to the sliding plate 5. When the sliding plate 5 is raised or lowered to adjust its height, it drives the lifting block 15 to slide up and down in the square through slot on the fixed post 14, controlling the lifting direction and path of the sliding plate 5. The lower surface of one of the fixed posts 14 has a mounting slot, in which a third servo motor 16 is fixedly connected. The main shaft of the third servo motor 16 is fixedly connected to a second screw 17. The second screw 17 passes through the lifting block 15 and is threadedly connected to the lifting block 15. The lifting of the lifting block 15 is driven by the third servo motor 16 driving the second screw 17, which is the same as the lateral movement of the sliding seat 6. No adjustment is required by the operator, making it more labor-saving.

[0029] like Figure 3 and Figure 4As shown, the multi-height limiting component 9 includes two fixed plates 91, which are fixedly connected to the fixed column 14. A fourth servo motor 92 is fixedly connected to one side of one of the fixed plates 91. The main shaft of the fourth servo motor 92 is fixedly connected to the mounting rod 93. Four blocking blocks 94 are fixedly connected to the outer side of the mounting rod 93. The four blocking blocks 94 are arranged in a vertical array, and the distance between the four blocking blocks 94 is the same as the distance between the four locking blocks 84. A square notch is provided on one side of the lifting block 15 near the mounting rod 93. The square notch cooperates with the blocking block 94. When the sliding plate 5 moves vertically up and down, the lifting block 15 on one side contacts the first blocking block 94 and is blocked by the blocking block 94, and the sliding plate 5 stops. At this time, the sliding... The sliding seat 6 moves laterally to detect four points. Then, the fourth servo motor 92 drives the mounting rod 93 to rotate, the blocking block 94 disengages from the lifting block 15, and the sliding plate 5 descends. After passing the first blocking block 94, the fourth servo motor 92 drives the mounting rod 93 to reverse, causing the sliding plate 5 to be blocked by the second blocking block 94. The sliding seat 6 moves again to detect four points, and so on, until four points are detected at four different heights, thus achieving the detection of sixteen points. The horizontal and vertical spacing of the sixteen points is the same, which is the same as the required spacing. The whole process does not require the participation of personnel, is convenient to use, saves manpower, and can be operated by a single person. During the detection process, the personnel only need to record the data.

[0030] like Figure 5 As shown, two support plates 18 are fixedly connected to one side of the sliding seat 6, and a mounting ring 19 is fixedly connected to one end of each support plate 18. The intelligent rebound device 7 is installed inside the mounting ring 19. Two sliding rods 20 are slidably connected to the mounting ring 19. One end of each sliding rod 20 is fixedly connected to an annular plate 21. The annular plate 21 and the intelligent rebound device 7 are on the same axis. An annular sponge block is fixedly connected to one side of the annular plate 21. After the annular sponge block is soaked in ink, it can leave a marking circle on the wall. One end of each sliding rod 20 is fixedly connected to a limiting block. A spring is fixedly connected between the limiting block and the mounting ring 19. The distance between the sponge block and the mounting ring 19 is greater than the distance between the intelligent rebound device 7 and the mounting ring 19. When testing near the wall, the annular sponge block contacts the wall first, leaving a circle marking on the wall. Then, the intelligent rebound device 7 contacts the wall for testing. The detection point coincides with the center of the marking circle. By leaving a marking circle, it is convenient for staff to quickly find the detection point for subsequent comparison and inspection.

[0031] Working principle: The operator pushes the device, moving the base 1 to make it stand against the wall for testing. The first servo motor 11 drives the first screw 12 to rotate, and the sliding seat 6 drives the intelligent rebound device 7 to move laterally. The sliding seat 6 touches the locking block 84, which slides into the fixed cylinder 83 to avoid it. When the locking block 84 is aligned with the slot, it enters the slot, stopping the sliding seat 6. After stopping, the housing 1 moves under the push of the electric push rod, approaching the wall. The annular sponge block contacts the wall first, leaving a circular mark on the wall. Then the intelligent rebound device 7 contacts the wall for testing. After the test is completed, the second servo motor 81 drives the round rod 82 to rotate, causing the locking block 84 to rotate out of the slot. The first servo motor 11 drives the sliding seat 6 to move. After leaving the locking block 84, the second servo motor 81 drives the round rod 82 to rotate. Rotate to reset the locking block 84, wait for the second locking block 84 to lock the sliding seat 6, and perform another test. After four horizontal tests, the third servo motor 16 drives the second screw 17 to rotate, the sliding plate 5 moves downward, and the lifting block 15 on one side contacts the first blocking block 94 and is blocked by the blocking block 94, so the sliding plate 5 stops. At this time, the sliding seat 6 moves horizontally to test four points. Then, the fourth servo motor 92 drives the mounting rod 93 to rotate, the blocking block 94 disengages from the lifting block 15, the sliding plate 5 descends, and after passing the first blocking block 94, the fourth servo motor 92 drives the mounting rod 93 to reverse, so that the sliding plate 5 is blocked by the second blocking block 94, the sliding seat 6 moves again to test four points, and so on, until four points are tested at four different heights, thus realizing the testing of sixteen points.
