Description

Technical Field

[0001] This utility model belongs to the technical field of transportation testing equipment, specifically relating to a portable tensile testing instrument. Background Technology

[0002] In the field of container shipping, ensuring the safe and stable reinforcement of cargo is a crucial step in guaranteeing the smooth operation of the transportation process. This is especially true for easily rolling cargo and special containers, where the level of reinforcement directly affects transportation safety and efficiency. However, in the actual process of inspecting the reinforcement of easily rolling cargo and special containers, inspectors often face numerous challenges.

[0003] On the one hand, the internal structure of shipping containers is complex, with numerous narrow and hard-to-reach areas. Due to space constraints, inspectors often cannot directly enter these areas, making it impossible to effectively determine whether the cargo reinforcement within these areas meets the stringent requirements for safe container transport. The existence of these blind spots greatly increases the difficulty and risk of inspection, potentially leading to the omission of reinforcement issues and thus threatening transport safety.

[0004] On the other hand, traditional inspection methods are relatively rudimentary, with inspectors typically relying solely on personal experience and intuitive judgment to assess whether the reinforcement of goods inside the container meets standards. This method lacks scientific rigor and accuracy, is easily influenced by subjective factors, and makes it difficult to ensure the reliability and consistency of inspection results. Furthermore, due to a lack of specialized testing tools, inspectors cannot comprehensively and objectively assess the reinforcement status of the goods. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the lack of professional testing tools prevents inspectors from assessing the reinforcement status of goods. This invention provides a portable tensile testing instrument to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A portable tensile testing instrument includes a testing rod, a camera assembly, a tensile gauge fixed to one end of the testing rod, a handheld testing terminal, and a power module that powers the entire instrument. A tension hook is fixed to the end of the tensile gauge away from the testing rod, the camera assembly is installed at the end of the testing rod close to the tensile gauge, and the tensile gauge is wirelessly connected to the handheld testing terminal.

[0008] A further improvement to this technical solution is that the detection rod adopts a three-section telescopic rod.

[0009] A further improvement to this technical solution is that a telescopic button is provided at the connection point of the two telescopic rods to fix the telescopic rod.

[0010] A further improvement to this technical solution is that the detection rod is made of aluminum alloy.

[0011] Further improvements to this technical solution include a camera assembly comprising a mounting base, a rotating ball head, and a camera. The mounting base is fixed to a telescopic rod, the rotating ball head is fixed to the end of the mounting base away from the telescopic rod, and the camera is fixed to the end of the rotating ball head away from the mounting base. The camera is wirelessly connected to a handheld detection terminal.

[0012] A further improvement to this technical solution is that the rotating spherical gimbal is model BH01.

[0013] A further improvement to this technical solution is that the camera component also includes a lighting lamp, which is wirelessly connected to the handheld detection terminal.

[0014] A further improvement to this technical solution is that a display screen is installed on the handheld testing terminal.

[0015] The beneficial effects of this invention are as follows: Through the design of a portable tensile testing instrument, it enables real-time observation and tensile testing of cargo reinforcement in narrow, hard-to-reach areas inside containers, eliminating blind spots and improving inspection efficiency and accuracy. Furthermore, inspectors can use the instrument without entering the container, ensuring their inherent safety. Additionally, the three-section telescopic rod design and telescopic button allow the instrument to flexibly adjust its length and fixed position according to the size of the container's interior space, enhancing adaptability and convenience. The rotating spherical gimbal design achieves comprehensive coverage of narrow areas such as the container top and side wall gaps. Finally, the lighting and display screen allow inspectors to clearly observe cargo reinforcement even in low-light conditions, providing strong assurance for transportation safety.

[0016] Furthermore, the design principle of this utility model is reliable, the structure is simple, and it has a very wide range of application prospects.

[0017] It is evident that this utility model has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] like Figure 1 As shown, this utility model provides a portable tensile testing instrument, including a testing rod, a camera assembly, a tensile gauge fixed to one end of the testing rod, a handheld testing terminal, and a power module that supplies power to the entire testing instrument. A tensile hook is fixed to the end of the tensile gauge away from the testing rod, the camera assembly is installed at the end of the testing rod close to the tensile gauge, and the tensile gauge is wirelessly connected to the handheld testing terminal.

[0024] Specifically, the force gauge used is a Byes-SF-2N model.

[0025] In addition, the testing rod adopts a three-section telescopic rod (three-stage sleeve design), and a telescopic button (spring-assisted button) is set at the connection of the two telescopic rods to fix the telescopic rod. The testing rod is made of 6061-T6 aluminum alloy (tensile strength ≥310MPa, surface hard anodized treatment).

[0026] In practical applications, a large number of containers need to be inspected for cargo reinforcement on a daily basis. When using the portable tensile testing instrument of this invention, inspectors can flexibly adjust the testing rod according to the actual situation when encountering containers with complex internal spaces.

[0027] For example, in a standard 40-foot container, narrow passageways formed by stacked equipment and goods make it difficult for ordinary inspection tools to reach. In this case, inspectors extend the three-section telescopic rod of the inspection arm. Due to its three-stage sleeve design, the diameter of each telescopic section decreases sequentially and they nest tightly together, allowing for smooth extension. When the inspection arm needs to be fixed in length, the inspector simply presses the telescopic button at the connection point of two sections. This button uses a spring-assisted design; when pressed, the internal spring is compressed, and the button engages in a specific slot, thus stabilizing the relative position of the telescopic rod. This design allows inspectors to operate with one hand, quickly adjusting and fixing the inspection arm's length.

[0028] The inspection rod is made of 6061-T6 aluminum alloy, which is then shaped into a telescopic rod that meets dimensional requirements during manufacturing. Its surface undergoes hard anodizing treatment, effectively improving surface hardness and wear resistance. Under the container shipping company's daily high-intensity use, and after numerous impacts and frictions, the inspection rod maintains excellent performance without deformation or severe wear.

[0029] This invention utilizes a three-section telescopic rod (three-stage sleeve design) to adjust the length of the inspection rod within containers of varying sizes, enabling comprehensive inspection and significantly improving inspection range and efficiency. Furthermore, the telescopic button design (using a spring-assisted button) greatly simplifies the rod's fixing process. Compared to traditional bolt fixing methods, the spring-assisted button allows for instant fixing, reducing operator time. Its one-handed operation capability also allows operators to easily handle complex environments, enhancing the convenience of the inspection process. The 6061-T6 aluminum alloy material itself possesses excellent tensile strength ≥310MPa, capable of withstanding significant tensile forces without deformation. During actual inspections, when the inspection rod needs to penetrate narrow spaces, it may be subject to pressure from surrounding goods or structures; this material ensures the structural integrity of the inspection rod. The hard anodized surface treatment further enhances the rod's wear and corrosion resistance, enabling it to operate stably for extended periods in complex container environments, such as those with humidity and corrosive gases, extending its service life and reducing equipment maintenance costs.

[0030] In addition, the camera assembly includes a mounting base, a rotating ball head, and a camera. The mounting base is fixed to the telescopic rod, the rotating ball head is fixed to the end of the mounting base away from the telescopic rod, and the camera is fixed to the end of the rotating ball head away from the mounting base. The camera is wirelessly connected to the handheld inspection terminal. The handheld inspection terminal is equipped with a display screen (which can be a touch screen) and corresponding buttons.

[0031] In routine container cargo securing and inspection work, camera components play a crucial role. For example, when inspecting a special container loaded with precision instruments, the container's interior layout is compact, the cargo is densely packed, and there are many small, poorly lit corners. Inspectors bring a portable tensile testing instrument into the container, at which point the camera component's mounting base is already securely fixed to the telescopic rod of the testing arm. The mounting base uses a clip-on design; by tightening the screws, it can fit tightly against the surface of the telescopic rod, ensuring that there is no shaking or displacement during the inspection process.

[0032] After the mounting base is secured, the rotating ball head is installed at the end furthest from the telescopic rod. Taking the BH01 model rotating ball head as an example, it is connected to the mounting base using matching bolts, making the installation process simple and secure. During inspection, inspectors can flexibly rotate the rotating ball head within a 360-degree horizontal range and a -90-degree to +90-degree vertical range as needed. For example, when inspecting the securing of goods at the top corner of a container, the inspector operates the handheld inspection terminal, and the rotating ball head quickly rotates, precisely aiming the camera at the target location.

[0033] The camera is fixed to the end of a rotating spherical pan-tilt unit furthest from the mounting base. It is a high-definition, low-light camera, capable of capturing clear images even in low-light conditions. The camera and handheld inspection terminal communicate wirelessly via a Wi-Fi module. Inside the container, inspectors receive real-time footage from the camera through the handheld terminal.

[0034] The rotating spherical gimbal design in the camera assembly provided by this invention allows the camera to rotate within an extremely wide range of angles, achieving omnidirectional visual coverage of the container's interior. Whether it's the container top, side wall gaps, or narrow spaces formed by stacked goods, the camera can flexibly adjust its angle for shooting, effectively eliminating blind spots during inspection and greatly improving the comprehensiveness and accuracy of the inspection. The wireless communication connection between the camera and the handheld inspection terminal allows inspectors to obtain real-time images of the cargo's securing status inside the container. This not only facilitates on-site inspection work, allowing inspectors to clearly observe the cargo's condition without directly entering dangerous or inaccessible areas, but also enables the storage and backup of images.

[0035] Furthermore, the camera assembly also includes a lighting unit, which is wirelessly connected to a handheld inspection terminal. In the inspection of older shipping containers, where the internal lighting system is often damaged and the cargo consists of irregularly shaped metal items stacked together, creating numerous shadowy areas, inspectors use the portable tensile testing instrument provided in this invention to enter the container. When it is necessary to inspect the cargo reinforcement in these severely poorly lit areas, the lighting unit plays a crucial role.

[0036] The light is installed near the camera, forming a compact and efficient inspection vision unit together with the rotating spherical head and the camera. Before entering the container, inspectors ensure that the wireless communication connection between the light and the handheld inspection terminal is normal. After turning on the light, it is extended into the container; or inspectors can control the light to turn on and off via the operation buttons on the touch screen interface of the handheld inspection terminal.

[0037] When it's necessary to examine the details of a cargo's binding point, inspectors operate a handheld inspection terminal, rotating the pan-tilt head to aim the camera and lighting at the target location. The high-definition, low-light camera, combined with ample illumination, captures a clear image of the cargo's binding point. Inspectors then observe the image in real-time through the handheld terminal to determine the tightness of the binding ropes (which can be combined with a tension gauge) and whether there are signs of wear.

[0038] In situations where the interior of a container is dimly lit or the lighting system is malfunctioning, the lighting lamp in this invention provides an additional light source, significantly improving the illumination conditions of the inspection environment. Combined with a high-definition low-light camera, it can capture clear, detailed images even in areas with severely insufficient light, enabling inspectors to accurately assess the securing status of the goods and effectively avoid inspection errors caused by lighting issues. This comprehensively improves the accuracy and reliability of inspections in low-light environments. The lighting lamp ensures light coverage in shadowed areas created by stacked goods and in every corner of the container, effectively eliminating blind spots caused by light obstruction. Combined with the omnidirectional viewing angle coverage of the camera assembly, it enables comprehensive and detailed inspection of the securing status of every part of the goods inside the container, further ensuring transportation safety and reducing transportation risks caused by problems with cargo securing.

[0039] The working principle of this portable tensile strength tester is as follows: The inspector holds one end of the testing rod, turns on the camera and light, and adjusts the angle before inserting the testing rod into the position to be tested. The inspector operates the testing rod to hook the cable tie with the pull hook, and applies force outward to pull the testing rod. The tensile strength gauge detects the tightness of the cable tie in securing the goods, and the detected tensile strength data is wirelessly transmitted to the handheld testing terminal for display. In addition, the camera takes a picture of the cable tie at the position to be tested, which is wirelessly transmitted to the handheld testing terminal and displayed on the touch screen to determine whether there are signs of wear on the cable tie.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
