[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 - Figure 3The utility model provides an embodiment: a regenerated concrete seismic detection device, including a workbench 1, the outer wall of the workbench 1 is fixedly connected to a fixing box 2, the interior of the fixing box 2 is fixedly connected to a motor 3, the output end of the motor 3 is fixedly connected to a fan-shaped toothed plate 4, the upper surface of the fan-shaped toothed plate 4 is fixedly connected to a concave wheel 5, the outer wall of the concave wheel 5 is provided with a transmission belt 6, the interior of the fixing box 2 is slidably connected to a double-sided toothed plate 7, the fan-shaped toothed plate 4 is meshed with the double-sided toothed plate 7, one end of the double-sided toothed plate 7 is fixedly connected to a connecting rod 8, and the outer wall of the connecting rod 8 is fixedly connected to A vibration bin 9 is connected, the outer wall of the vibration bin 9 is slidably connected to the inside of the workbench 1, a guide assembly is provided on the outer wall of the vibration bin 9, a telescopic rod 10 is fixedly connected to the inner wall of the workbench 1, a telescopic spring 11 is sleeved on the outer wall of the telescopic rod 10, one end of the telescopic spring 11 is fixedly connected to the inner wall of the workbench 1, and the other end of the telescopic spring 11 is fixedly connected to the outer wall of the vibration bin 9, and the guide assembly includes a limit bar 12, one side of the outer wall of the limit bar 12 is fixedly connected to the outer wall of the vibration bin 9, and the other side of the outer wall of the limit bar 12 is slidably connected to the inside of the workbench 1;
[0026] Specifically, first, the concrete component to be detected is accurately placed inside the vibration bin 9, and then the motor 3 is started. Its output end will drive the sector tooth plate 4 to start rotating, which not only drives the cam wheel 5 to rotate, but also transmits power to the sector tooth plate 4 on the other side through the transmission belt 6, so that it rotates synchronously. Due to the meshing relationship between the two sector tooth plates 4 and the double-sided tooth plates 7, the two sector tooth plates 4 will drive the double-sided tooth plates 7 to reciprocate inside the fixed box 2. As the double-sided tooth plates 7 move, the connecting rod 8 and the vibration bin 9 will be driven to reciprocate together. In this process, the limit bar 12 plays a key guiding role to ensure that the moving trajectory of the vibration bin 9 is accurate. At the same time, the telescopic spring 11 will be telescoped during the movement of the double-sided tooth plate 7, providing assistance and buffering for the movement of the vibration bin 9, ensuring that the whole process is smooth and smooth. During the movement of the vibration bin 9, the concrete components inside it will be affected by the corresponding vibration, which can help detect the quality and performance of the concrete components. Finally, by adjusting the speed of the motor 3, the degree and frequency of vibration can be controlled to meet different detection requirements.
[0027] Reference Figure 1 , Figure 4 and Figure 5The interior of the vibration bin 9 is fixedly connected with a motor 2 13, the output end of the motor 2 13 is fixedly connected with a rotating plate 14, both ends of the rotating plate 14 are rotatably connected with a connecting rod 15, one end of the connecting rod 15 is rotatably connected with a slide plate 16, the lower surface of the slide plate 16 is fixedly connected with a guide rail 17, the outer wall of the guide rail 17 is fixedly connected to the interior of the vibration bin 9, the upper surface of the slide plate 16 is fixedly connected with a sliding block 18, the interior of the sliding block 18 is rotatably connected with a V-shaped clamp 19, the interior of the V-shaped clamp 19 is fixedly connected with a rotating shaft 20, the interior of the rotating shaft 20 is rotatably connected with a fixed rod 21, both ends of the fixed rod 21 are fixedly connected to the interior of the sliding block 18, the outer wall of the fixed rod 21 is provided with a torsion spring 22, one end of the torsion spring 22 is fixedly connected to the interior of the sliding block 18, and the other end of the torsion spring 22 is fixedly connected to the interior of the rotating shaft 20;
[0028] Specifically, after the concrete component is placed inside the vibration bin 9, the output end of the motor 2 13 will drive the rotating plate 14 to start rotating. The rotation of the rotating plate 14 is not isolated, but is closely connected with the connecting rods 15 on both sides. As the rotating plate 14 rotates, the connecting rod 15 will move accordingly. The other end of the connecting rod 15 is connected to two slides 16. When the connecting rod 15 moves, it will drive the slide 16 to move inside the vibration bin 9. In order to ensure that the movement of the slide 16 is stable and reliable, the guide rail 17 is used to guide it. The guide rail 17 not only provides a clear moving path for the slide 16, but also ensures the smoothness and accuracy of its movement. As the slide 16 moves, the sliding blocks on both sides 18 will move relatively, so that the V-shaped clamp 19 fits better with the concrete component. When the sliding block 18 moves to the appropriate position, the V-shaped clamp 19 will be supported by the component and will start to rotate inside the sliding block 18 until the two corners of the V-shaped clamp 19 fit completely with the concrete component, which can ensure that the concrete component will not move or deform during the test. The rotation of the V-shaped clamp 19 is not isolated, and it will drive the shaft 20 and the torsion spring 22 to rotate together. In this process, the torsion spring 22 will reverse and store a certain amount of elastic potential energy. When the test is over, the torsion spring 22 will use the stored elastic potential energy to rotate and drive the V-shaped clamp 19 back to its original state. It is fully prepared for the next use.
[0029] Working principle: when it is necessary to use the recycled concrete seismic detection device, first place the concrete component inside the vibration bin 9, and then drive the fan-shaped toothed plate 4 to rotate through the output end of the motor 3, and at the same time, drive the cam wheel 5 to rotate through the rotation of the fan-shaped toothed plate 4, and then cooperate with the transmission belt 6 to drive the fan-shaped toothed plate 4 on the other side to rotate synchronously. Due to the meshing of the fan-shaped toothed plate 4 and the double-sided toothed plate 7, the two fan-shaped toothed plates 4 drive the double-sided toothed plate 7 to reciprocate inside the fixed box 2, and then drive the connecting rod 8 and the vibration bin 9 to reciprocate through the movement of the double-sided toothed plate 7. This process is guided by the limit strip 12, so that the telescopic spring 11 is retracted to assist the movement of the vibration bin 9. Finally, the vibration degree can be adjusted by controlling the speed of the motor 3 to achieve the effect of vibration detection. When the concrete component is placed inside the vibration bin 9, it can be driven by the output end of the motor 13 The movable rotating plate 14 rotates, thereby driving the connecting rods 15 on both sides to move, and then the other end of the connecting rod 15 drives the two slide plates 16 to move inside the vibration chamber 9. In this process, the movement of the slide plate 16 is guided by the guide rail 17, and then the two slide plates 16 drive the sliding blocks 18 on both sides to move relatively, and then the movement of the sliding block 18 drives the V-shaped clamp 19 to fit with the concrete component, so that the V-shaped clamp 19 rotates inside the sliding block 18. When it is rotated until the two angles are evenly fitted with the concrete component, concrete components of different shapes can be clamped and fixed. In this process, the rotation of the V-shaped clamp 19 drives the rotating shaft 20 and the torsion spring 22 to rotate, so that the torsion spring 22 is reversed. When the test is completed, the rotation of the torsion spring 22 can drive the V-shaped clamp 19 to return to its original state, so as to facilitate the next use and achieve the effect of fixing the concrete component.
