Description

Technical Field

[0001] This utility model relates to the field of cargo packaging stacking inspection technology, and in particular to a dangerous goods packaging stacking inspection device. Background Technology

[0002] With various industries continuously raising their standards for cargo transportation safety, ensuring the safety of dangerous goods during transport has become a crucial aspect. Simultaneously, the lithium battery industry is experiencing rapid growth, with lithium batteries, as a type of dangerous goods, seeing a dramatic increase in both production and transportation volume. This trend has directly spurred the booming development of the dangerous goods packaging industry, as safe and reliable packaging is a vital prerequisite for preventing leaks, explosions, and other dangerous accidents during the transportation and storage of dangerous goods.

[0003] With the growth of the dangerous goods packaging industry, the demand for related testing is also increasing daily. Among the many testing items, the stacking test, as a routine and critical item for testing the performance of dangerous goods packaging, is of paramount importance. The stacking test aims to simulate the pressure exerted on dangerous goods packaging by stacked goods during actual warehousing and transportation, thereby verifying the strength and stability of the packaging and ensuring that it will not deform or break under certain pressure, thus guaranteeing the safety of the dangerous goods inside.

[0004] According to the requirements of GB / T 4857.3 standard, there are three main implementation methods for stacking tests: package group method, free-loading plate method, and guided loading plate method. Currently, in practical applications, the free-loading plate method and the sampling stacking / compression testing machine method are more commonly used.

[0005] One method, the free-loading plate method, involves stacking weights or other heavy objects on a rigid plate to apply pressure. However, this method has several drawbacks. Firstly, it requires handling a large amount of heavy material, which not only consumes significant manpower and increases labor intensity but also poses safety risks, such as injury from tipping over. Secondly, because the load's center of gravity is difficult to precisely align with the sample's center, it significantly affects the consistency of test results, leading to large deviations in data from different tests and failing to accurately reflect the true performance of the packaging.

[0006] The sampling stacking / compression testing machine applies pressure through a hydraulic system and uses sensor feedback to control the pressure level. However, this type of equipment also has some issues that cannot be ignored. First, the initial investment cost is relatively high, which can place a significant financial burden on small businesses or testing institutions when purchasing and maintaining such a system. Second, the equipment requires a large footprint and a dedicated space for placement and operation, which can be limiting in situations with limited space. Furthermore, instability such as sensor data drift can occur frequently, leading to inaccurate pressure control and consequently affecting the accuracy and reliability of the test results.

[0007] In summary, existing stacking test methods all have certain limitations and cannot fully meet the requirements of dangerous goods packaging inspection for efficiency, accuracy, and safety.

[0008] Therefore, this application aims to provide a dangerous goods packaging stacking inspection device to better solve the above-mentioned technical problems. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1-2As shown, the dangerous goods packaging stacking inspection device described in this embodiment includes a support assembly 1, a lifting assembly 2, and a limiting and protective assembly 3. The support assembly 1 has a base 11, a support guide column 12, a movable plate 13, and a top plate 14. The movable plate 13 and the top plate 14 are connected to the base 11 through the support guide column 12, and the movable plate 13 is located between the base 11 and the top plate 14 for placing test weights. The base 11 has a base plate 15 with positioning scale for placing the sample to be tested. The support guide column 12 has marking scale for measuring the position change value of the movable plate 13. The lifting assembly 2 is installed on the top plate 14 and connected to the movable plate 13 for driving the movable plate 13 to move up and down, so that the movable plate 13 rises above the height of the sample to be tested for placing the sample, or descends to completely press on the sample to be tested for testing. The limiting and protective assembly 3 is installed on the base 11 and the top plate 14 respectively to prevent the movable plate 13 from rising or falling excessively.

[0029] This embodiment features a simple structure, low cost, and ease of operation. During use, the lifting assembly 2 controls the up-and-down movement of the movable plate 13, and the positional changes of the movable plate 13 are recorded using the markings on the support guide column 12. Stable and efficient testing is achieved, and the operation is safe and convenient. Specifically, the operator controls the lifting assembly 2 to raise the movable plate 13 to a position higher than the test sample height. Appropriate weights are placed on the movable plate 13 according to the stacking load requirements of the test sample, and the sample is placed in the center of the base plate 15 (the sample position is adjusted based on the positioning scale on the base plate 15 to ensure the sample is in the center). The markings on the support guide column 12 are observed and recorded. Then, the lifting assembly 2 is lowered, pressing the movable plate 13 onto the sample until the lifting assembly 2 is no longer under tension. At this point, the weight pressing on the sample is equal to the sum of the weights and the weight of the movable plate 13 itself. The scale value of the lower edge of the movable plate 13 on the support guide column 12 is recorded to obtain the deformation of the sample. After the test, the state of the test sample is observed to determine whether the test has passed.

[0030] Specifically, in this embodiment, in order to ensure the stability of the overall device, in addition to the supporting guide column 12, a connecting column 5 can be added to connect the base plate 15 and the top, so as to further increase the stability of the connection.

[0031] In some embodiments, the movable plate 13 is provided with a lifting ring 16, and the lifting assembly 2 is connected to the lifting ring 16 via a steel wire rope 4, thereby driving the movable plate 13 to move up and down.

[0032] Specifically, the steel wire rope 4 is a flexible steel wire rope 4.

[0033] In this embodiment, there is a lifting ring 16 on the movable plate 13. The lifting assembly 2 is connected to the lifting ring 16 by a flexible steel wire rope 4 to drive the lifting. The combination of the lifting ring 16 and the steel wire rope 4 is more flexible, the movement is smooth, and the lifting operation is convenient.

[0034] In some embodiments, the limiting protection component 3 is provided with a limit switch 31 and a limit post 32, the limit post 32 is installed on the base plate 15, and the limit switch 31 is installed on the top plate 14.

[0035] In this embodiment, the cooperation of limit switch 31 and limit post 32 can be used to control the lifting range of movable plate 13. When movable plate 13 rises to a predetermined position, limit switch 31 is triggered to stop, preventing excessive rising; limit post 32 can play the role of hard limit, avoiding pressing on the operator during operation and improving operation safety.

[0036] In some embodiments, a guide sleeve 17 is provided at the position where the movable plate 13 is connected to the support guide post 12, and the guide sleeve 17 has balls inside.

[0037] In this embodiment, a guide sleeve 17 with internal balls is provided at the connection position between the movable plate 13 and the support guide column 12, which can minimize the friction between the movable plate 13 and the support guide column 12 and ensure the smooth movement of the movable plate 13.

[0038] In some embodiments, the base 11 is provided with supporting feet or movable casters at its bottom end.

[0039] In this embodiment, a support pad is provided at the bottom of the base 11 to provide stable support and prevent slippage; while a movable pulley is provided to facilitate the movement of the device to adapt to different test scenarios and improve flexibility.

[0040] In some embodiments, the lifting assembly 2 is provided with a control unit 21 and a lifting motor 22.

[0041] In this embodiment, the control unit 21 can be used to precisely control the speed and position of lifting and lowering, and the motor provides power to achieve precise and flexible lifting and lowering operations, thereby improving testing efficiency and accuracy.

[0042] In some embodiments, see Figure 1-2 As shown, the movable plate 13 is provided in a set, the number of the supporting guide columns 12 is matched with the number of the movable plates 13, and the lifting components 2 are respectively connected to a set of the movable plates 13.

[0043] In this embodiment, a set of movable plates 13 is provided, and a corresponding number of supporting guide columns 12 are provided. The lifting component 2 can control each movable plate 13 simultaneously or separately to be suitable for testing samples of different sizes or quantities, thereby improving the applicability and expandability of the device. For testing more samples, the number of movable plates 13 can be further expanded.

[0044] Additionally, it should be noted that, for the sake of clarity, the attached diagram will be... Figure 1-2 The markings on the central support guide column 12 and the base plate 15 are not displayed. The actual device needs to be marked with markings for sample testing.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
