However, when the existing dynamic deformation tester standard device is measuring, the guide rod fixing device and the displacement sensor fixing device need to be fixed to the wall before measurement can be performed, resulting in the dynamic deformation tester standard device being limited by the usage scenario when performing testing. Utility Model Content
[0003] The purpose to be achieved by the utility model is to provide a standard device of a dynamic deformation tester, so as to solve the problem that the use scenarios of the standard device of the dynamic deformation tester are limited during testing.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a standard device of a dynamic deformation tester, including a concrete foundation, a steel base, a guide rod fixing frame, and a displacement sensor. The steel base is fixed to the upper surface of the concrete foundation and is used to place the object to be tested and protect the concrete foundation during the impact test; the displacement sensor is used to measure the displacement of the object to be tested during the test, and is characterized in that the guide rod fixing frame is arranged on the side of the concrete foundation, the guide rod fixing frame includes a fixing frame frame, a guide column with a bottom supported by the fixing frame frame, and a guide rod connecting bracket and a displacement sensor bracket arranged on the guide column, and the displacement sensor bracket is connected to the displacement sensor.

[0038] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0039] like Figures 1 to 10 As shown, the utility model provides a standard device of a dynamic deformation tester, including a concrete foundation 1, a steel base 2, a guide rod fixing frame 3, and a displacement sensor 5. The steel base 2 is fixed to the upper surface of the concrete foundation 1, and is used to place the object to be tested and protect the concrete foundation 1 during the impact test; the displacement sensor 5 is used to measure the displacement of the object to be tested during the test, and is characterized in that the guide rod fixing frame 3 is arranged on the side of the concrete foundation 1, and the guide rod fixing frame 3 includes a fixing frame frame 31, a guide column 32 whose bottom is supported on the fixing frame frame 31, and a guide rod connecting bracket 33 and a displacement sensor 5 arranged on the guide column 32. The displacement sensor bracket 34 is connected to the displacement sensor 5. By designing the guide rod fixing frame 3, when the dynamic deformation tester standard device is measured, it will not be restricted by the use scene such as the wall. Since the guide rod fixing frame 3 is designed on the side of the concrete foundation 1, rather than directly relying on external supports such as the wall, the whole device is more flexible, and the dynamic deformation tester standard device is easier to move and deploy in different scenes, so that the applicability of the dynamic deformation tester standard device is improved. The close connection between the components not only enhances the overall stability of the device, but also simplifies the assembly and disassembly process of the device. The dynamic deformation tester standard device can choose to test the impact and displacement functions. In addition, in order to ensure the protection of the concrete foundation 1 during the impact test, the use of a steel base 2 is a common solution. The steel base 2 can provide additional support and protection, reduce the impact of the impact force on the concrete foundation 1, and evenly disperse the impact force to a larger surface area, reduce the local pressure on the concrete foundation 1, and provide a certain shock absorption and buffering effect.
[0040] Specifically, the displacement sensor bracket 34 is provided with a displacement sensor position adjustment structure 35, which is used to adjust the position of the displacement sensor 5 to ensure that the displacement sensor 5 is in contact with the object to be measured. Through the displacement sensor position adjustment mechanism 35, the position of the displacement sensor 5 can be accurately adjusted to improve the accuracy and precision of the measurement. One end of the displacement sensor position adjustment mechanism 35 is detachably connected to the guide rod 32, thereby connecting the entire displacement sensor bracket 34 to the guide rod 32. Such a design can not only improve the overall stability of the dynamic deformation tester standard device, but also expand the use scenario and measurement range of the dynamic deformation tester standard device by adjusting the displacement sensor position adjustment mechanism 35 at the position of the guide rod 32. Specifically, the measurement range of the displacement sensor 5 is ±5mm, and a smaller measurement range helps to improve the accuracy of the test results and reduce the error probability of the test results.
[0041] In order to facilitate timely data collection and analysis and processing, a computer placement plate 36 is provided on the guide column 32, and the plate surface of the computer placement plate 36 faces upward. The computer placement plate 36 on which the computer 6 can be placed is adjusted to ensure that there is a flat plate surface on the standard device of the dynamic deformation tester. The design of the computer placement plate 36 allows the operator to place the computer 6 or the data acquisition device during the test, so as to detect and record the test data in real time, and realize a faster, more accurate, safer and more intelligent sample preparation process.

The guide rod connecting bracket 33 is connected to the guide rod drop hammer mechanism 4, and a buffer pad 45 for buffering the impact of the drop hammer 43 is provided at the bottom of the guide rod 42. The buffer pad 45 can reduce vibration and noise during impact. By increasing the thickness and elasticity of the buffer pad 45, a better shock absorption effect can be provided, the test equipment and the surrounding environment can be protected, the energy generated by the impact of the drop hammer 43 can be absorbed and dispersed, and the situation where the test has a large error due to excessive impact force can be avoided. It can also effectively slow down the impact force transmitted to other adjacent components, reduce the impact on the standard device of the dynamic deformation tester, and improve the safety of the standard device of the dynamic deformation tester.
[0043] Specifically, a handle 46 is provided on the chassis 41 . The provision of the handle 46 enables an operator to carry the chassis 41 more easily and to place the chassis 41 at a desired position quickly and accurately.
[0044] Specifically, the release assembly 44 is provided with a release handle 47. The setting of the release handle 47 provides a manual control method, so that the operator can more intuitively control the release of the drop hammer 43, thereby improving the accuracy and safety of the test process, reducing potential failure points, and there is no need to rely on complex control systems or electronic equipment. The operation can be completed manually, which is very convenient.
[0045] In this embodiment, the guide column 32 is an aluminum profile. Aluminum is easy to process and is also a recyclable material. Compared with other materials, it has a superior strength-to-weight ratio. While maintaining a certain strength, it is relatively light, easier to carry and install, and has good corrosion resistance. It is not easily affected by oxidation and corrosion, and is suitable for testing under different environmental conditions.
[0046] In this embodiment, the fixing frame frame 31 is a rectangular parallelepiped or a cube, and the four bottom corners of the fixing frame frame 31 are provided with legs 311.

Meanwhile, the legs 311 are provided at the four bottom corners of the fixing frame frame 31. Specifically, the legs 311 are detachable universal wheels with a braking function. The universal wheels have the ability to rotate 360°, can adapt to the ground in different environments, are convenient for mobile positioning, improve the overall flexibility of the fixing frame frame 31, and are also convenient for operators to carry the guide rod fixing frame 3 as a whole, and have low maintenance costs, and can be disassembled and replaced if damaged.
[0047] In this embodiment, the concrete foundation 1 is a cuboid or a cube, and a groove 11 is provided in the central area of the upper surface of the concrete foundation 1. The cuboid or the cube can improve the stability of the entire concrete foundation 1, thereby providing better support for the guide rod drop hammer mechanism 4 and the displacement sensor 5, ensuring smooth detection.
