[0029] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1 to 4 As shown, a floor impact testing device includes a support plate 1, a floor clamping structure 3, two movable grooves 4, a longitudinal moving structure 8, a transverse moving structure 9, support rods 10, an impact hammer 11, and a control box 12. A protective box 2 is fixedly connected to the top of the support plate 1. The front of the protective box 2 is open and equipped with a protective door 14. The protective box 2 prevents debris from flying out during the impact test, thus avoiding injury to workers. Transparent panels are provided on both sides and the rear of the protective box 2, and a transparent protective window is provided in the protective door 14, allowing for observation of the test process and results while providing safety protection. A safety lock is also provided to ensure sealing during the test, making it more convenient and safer to use. The floor clamping structure 3 is located on top of the support plate 1 and is used to clamp the floor, preventing displacement due to floor vibration during the impact test, which could lead to inaccurate test results. Two movable grooves 4 are located on both sides of the floor clamping structure 3, and guide rods 5 are fixedly connected within the two movable grooves 4. 5. Movable blocks 6 are sleeved on both ends. A support rod 7 is fixedly connected to the top of the movable block 6. The support rod 7 is connected to both ends of the floor clamping structure 3. During the impact test of the floor, the guide rod 5 and the support rod 7 work together to bear part of the impact force, so as to avoid the large force of the entire floor impact test from damaging the adjustment components in the floor clamping structure 3 and affecting its use. The longitudinal moving structure 8 is located on the top of the protective box 2, the transverse moving structure 9 is located below the longitudinal moving structure 8, the fixed rod 10 is located at the bottom of the transverse moving structure 9, and the impact hammer 11 is located at the bottom of the support rod 10. The impact hammer is installed by the fixed rod 10, and the position of the impact hammer 11 can be adjusted by the longitudinal moving structure 8 and the transverse moving structure 9. Thus, the impact force of the floor can be tested from multiple perspectives. The control box 12 is located at the bottom front of the bearing plate 1. The control box 12 controls the opening and closing of the electronic devices in the floor clamping structure 3, the longitudinal moving structure 8, the transverse moving structure 9 and the impact hammer 11.

[0031] The floor clamping structure 3 includes a movable groove 301, which is located at the top of the support plate 1. A bidirectional threaded rod 302 is rotatably connected within the movable groove 301. One end of the bidirectional threaded rod 302 extends out of the movable groove 301 and is fixedly connected to a motor 303. Movable blocks 304 are threadedly connected to both ends of the bidirectional threaded rod 302. The bottoms of the two movable blocks 304 slide within the movable groove 301, and the tops are fixedly connected to support frames 305. 05. A clamping groove 306 is provided on the top of the opposite side. A clamping plate 307 is provided in the clamping groove 306. One side of the clamping plate 307 is attached to the inner wall of the clamping groove 306. A threaded rod 308 is rotatably connected to the top of the clamping plate 307. The threaded rod 308 passes through the top of the clamping groove 306 and is connected by a threaded structure. Before the floor is subjected to impact force test, the two ends of the floor are placed in the two clamping grooves 306, and the motor 303 is started to drive the bidirectional threaded rod 302 to rotate and engage the two movable parts. The first motor 304 is driven, which in turn moves the two support frames 305 and the clamping groove 306 closer to the end of the floor. After adjusting to the appropriate position, the first motor 303 is turned off, and the bidirectional threaded rod 302 stops rotating. Then, the first threaded rod 308 is rotated, which pushes the clamping plate 307 against the top of the floor, thereby clamping the floor. This can prevent the floor from shifting during the impact test. At the same time, a certain amount of vibration will be generated during the impact test of the floor. Therefore, the thread structure at the top of the clamping groove 306 is an anti-loosening thread structure, which can prevent the vibration from causing the first threaded rod 308 to move and move the clamping plate 307 upward. The anti-loosening thread structure is existing technology, so it will not be described in detail. The tops of the two support rods 7 are fixedly connected to the bottom ends of the clamping plate 307. The height of the two guide rods 5 is slightly higher than that of the bidirectional threaded rod 302. The guide rods 5 and the support rods 7 can distribute the impact force to a certain extent and prevent damage to the bidirectional threaded rod 302.

[0032] The longitudinal moving structure 8 includes a movable groove 801, which is longitudinally opened at the top of the protective box 2. A threaded rod 802 is rotatably connected inside the movable groove 801. One end of the threaded rod 802 extends out of the protective cover 2 and is fixedly connected to a motor 804. A movable block 805 is connected to the external threaded structure of the threaded rod 802. When the motor 804 is started, the threaded rod 802 is driven to rotate inside the movable groove 801, thereby driving the transverse moving structure 9 to move longitudinally through the movable block 801, and thus adjusting the impact hammer 11 laterally.

[0033] The lateral movement structure 9 includes a movable plate 901, which is fixedly connected to the bottom of the movable block 805. The top of the movable plate 901 has a movable groove 902. One end of the movable groove 902 is rotatably connected to a threaded rod 903, and the other end of the threaded rod 903 is fixedly connected to a motor 904. The end of the motor 904 away from the threaded rod 903 is fixedly connected to the end of the movable groove 902. The threaded structure of the threaded rod 903 is connected to the movable block 905. The bottom of the movable block 905 is fixedly connected to the top of the support rod 10. The threaded rod 903 driven by the motor 904 drives the movable block 905 to move laterally. The fixed rod 10 is vertically fixed to the bottom of the movable block 905, and an impact hammer 11 is installed at the end. The top of the front and rear sides of the protective box 2 has a bearing groove 13. The two ends of the movable plate 901 slide in the bearing groove 13. The two ends of the movable plate 901 are embedded in the bearing groove 13 at the top of the protective box 2 to enhance the stability during lateral movement.

[0034] In practical use: Open the protective door 14, place the floor sample between the clamping slots 306 of the two support frames 305, start the motor 303 to drive the bidirectional threaded rod 302 to rotate, causing the two movable blocks 304 to move towards each other, driving the support frame 305 to clamp the two sides of the sample. Manually rotate the threaded rod 308 to push the clamping plate 307 downward to press the sample surface. The anti-loosening thread structure prevents loosening during the test. Start the motor 804 through the control box 12 to drive the movable block 805 to move longitudinally along the movable slot 801 to the target height. Start the motor 904 to drive the movable block 905 to move laterally along the movable slot 902. Adjust the horizontal position of the impact hammer 11 so that the hammer head is aligned with the preset impact point of the sample. Control the impact hammer 11 to fall freely or drive it to apply impact force. After the test is completed, record the sample damage state through the transparent observation window. After the test is completed, reverse the operation to release the clamping structure and take out the sample.
