Description

Technical Field

[0001] This utility model relates to the field of workshop storage equipment technology, and in particular to an automated material feeding and non-destructive testing container room. Background Technology

[0002] In traditional nondestructive testing (NDT) operations, there are many technical challenges in the testing of centralizers, which severely restrict testing efficiency and operational safety. In the workpiece transfer process, the centralizers to be tested are heavy and rely entirely on manual handling to move them to the testing station. This purely manual operation mode not only increases the labor intensity of operators and makes them prone to limb strain after long-term operation, but also makes it difficult to guarantee the accuracy of manual alignment. The workpieces often shift, requiring repeated adjustments and calibrations, which not only prolongs the test preparation time but also has a potential impact on the accuracy of subsequent test data.

[0003] The fragmented testing process has become a bottleneck to efficiency. Core processes such as pretreatment, testing, and material handling lack a coherent operational mechanism. Each process requires dedicated personnel to operate, and the transfer of workpieces between processes relies on manual relay. This can easily lead to production stoppages due to mismatched process rhythms. If the next process does not respond in time after the previous process is completed, the workpieces can only be temporarily piled up, causing chaos on the work site and delaying the overall testing progress. Traditional testing equipment has obvious deficiencies in safety protection and standardization. The mechanical moving parts of the equipment lack adequate protective devices, posing a safety risk to operators who may accidentally touch the moving parts during operation. At the same time, there are no unified technical standards for electrical system configuration and mechanical structure stability, making it prone to sudden power outages, abnormal mechanical vibrations, and other malfunctions during operation. This not only interferes with the continuity of normal testing work but also creates potential safety hazards in equipment operation. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an automated material feeding non-destructive testing chamber.

[0021] Example 1: Basic Structure and Automated Material Feeding Process Example This embodiment is a basic working scenario for an automated material feeding and non-destructive testing container room. It is applicable to the automated material feeding and non-destructive testing of small and medium-sized components (such as prefabricated building components and metal plates), and demonstrates the core components and collaborative operation logic of the device.

[0022] The main body 1 of the non-destructive testing container adopts a modular steel structure (wall thickness ≥4mm), with an overall size of 6m×3m×2.5m. It is fixed to the ground through the pre-set anchor bolt holes at the bottom and has the stability of wind resistance level ≥8. Two roller shutter door assemblies 2 (electric roller shutter doors, lifting speed 0.2m / s) are installed on the outer walls at the front and rear ends of the container. The front door is the material inlet and the rear door is the material outlet. The roller shutter doors are connected to the roller shutter door socket 11 (AC220V) inside the container through wires to realize electric opening and closing.

[0023] The top of the container is fixedly connected to four lifting lugs 3 (Q235 steel, load capacity ≥5t), which are arranged in a rectangular shape for hoisting and transporting the container. Two windows 4 (double-layer tempered glass, size 50cm×40cm) are installed on each of the two outer walls. The windows are equipped with blackout curtains, which facilitates observation of the internal testing situation and can also achieve blackout during darkroom testing (light transmittance ≤1%).

[0024] A support platform 17 (made of patterned steel plate, 8mm thick) is installed in the center of the container interior as the installation base for various functional assemblies. The self-rotating assembly 13 (including a servo motor and a rotating platform, with a load capacity of ≥500kg) is fixed in the middle of the bearing platform 17 and can drive the component to rotate 360° (rotation accuracy ±0.5°).

[0025] The lifting assembly 14 (hydraulic lifting column, lifting stroke 0-50cm) is installed below the self-rotating assembly 13 to realize the vertical height adjustment of the component.

[0026] The gear and rack transmission assembly 15 (including drive motor and rack guide rail, transmission accuracy ±1mm) is arranged along the length of the bearing platform 17 and is used to drive the components on the bearing platform 17 to move horizontally.

[0027] The material stop assembly 16 (pneumatic baffle, response time ≤0.5s) is installed at the feeding end of the bearing platform 17 and controls the feeding rhythm through the telescopic blocking component.

[0028] The internal facilities of the container include: exhaust fan assemblies 7 on both sides at the top (the frame is made of aluminum alloy, and the fan air volume is ≥1000m³ / h). 3 The container can be fixed with bolts to achieve air circulation inside and outside (air exchange rate ≥ 6 times / h).

[0029] The corner-mounted emergency light assembly 8 (LED light source, battery life ≥90min) automatically illuminates during power outages. The wall-mounted PLC control box assembly 10 (including Siemens S7-1200 PLC) serves as the core control unit, electrically connected to the control switch 9 and various assembly motors to realize automated control logic.

[0030] Storage box 6 (stainless steel, capacity ≥50L) is used to store testing tools. Air conditioner socket 12 (AC220V) is used in conjunction with air conditioner to maintain the temperature inside the chamber at 15-30℃.

[0031] The operator starts the system via control switch 9. The front door roller shutter assembly 2 automatically rises, and the gear and rack transmission assembly 15 drives the feed end of the support platform 17 to extend out of the chamber. After the component to be tested is placed on the support platform 17, the stop assembly 16 extends to fix the component, and the support platform 17 retracts into the main body 1 of the non-destructive testing chamber. The roller shutter assembly 2 closes. Subsequently, the lifting assembly 14 adjusts the height of the component, and the rotation assembly 13 drives the component to rotate, cooperating with the testing equipment inside the chamber to complete all-round non-destructive testing. After the testing is completed, the rear door roller shutter assembly 2 opens, and the component is sent out via the gear and rack transmission assembly 15. Example 2: Darkroom Detection Function Example This embodiment focuses on the darkroom testing scenario of the container room, and is applicable to testing projects that require a light-protected environment (such as fluorescence penetrant testing and X-ray film evaluation), demonstrating the environmental adaptability of the container room.

[0032] Close the blackout curtains on both sides of the windows 4 of the non-destructive testing chamber 1, and cut off the regular lighting inside the chamber through the darkroom switch (only the emergency light assembly 8 is kept on as a backup circuit), so that the interior of the chamber is a darkroom environment (light intensity ≤ 5 lux). The darkroom area corresponds to the testing station of the carrying platform 17. The inner wall is covered with radiation-proof lead plate (2 mm thick), which can shield the radiation during the testing process (protection level ≥ 0.5 mmPb).

[0033] Assembly adjustment in darkroom mode The PLC control box assembly 10 is preset to a darkroom detection mode. After startup, it automatically adjusts the operating logic of each assembly: the rotation speed of the self-rotating assembly 13 is reduced to 5r / min to facilitate slow scanning detection; the lifting assembly 14 automatically adjusts the height of the component according to the focal length of the detection equipment (adjustment accuracy ±1cm); and the material blocking assembly 16 remains in a retracted state to avoid blocking the detection light path.

[0034] Exhaust fan assembly 7 switches to low speed operation (air volume 500m³ / h) 3 / h), reducing airflow interference to the testing environment while maintaining air circulation in the darkroom. Operators can monitor in real time through the observation hole of window 4 (equipped with anti-radiation glass), or remotely view the test data through the touch screen of PLC control box component 10. After the test is completed, the darkroom switch is turned on to restore lighting, and the roller shutter component 2 automatically opens to complete the component discharge. The entire process does not require manual entry into the darkroom area of ​​the main body 1 of the non-destructive testing chamber, improving operational safety.

[0035] Example 3: PLC Automation Control Example This embodiment demonstrates the automated control logic of the PLC control box component 10, which is suitable for continuous inspection scenarios of batch components and improves inspection efficiency.

[0036] The PLC control box assembly 10 follows a pre-programmed detection process: When a component is placed on the support platform 17, the sensor (infrared beam sensor) of the baffle assembly 16 detects the component and triggers a signal to the PLC. The PLC then controls the rack and pinion drive assembly 15 to start, sending the component into the non-destructive testing chamber 1 and closing the roller shutter assembly 2. Following preset parameters, the lifting assembly 14 (raising to the detection height) and the rotation assembly 13 (setting the rotation angle) are started sequentially, simultaneously triggering the detection equipment to begin operation. After detection, the PLC receives the "detection complete" signal from the equipment, controls each assembly to reset, and the rear roller shutter assembly 2 opens to send out the component. Simultaneously, the front roller shutter assembly 2 opens to await the next component. The operator can switch modes via control switch 9. Manual mode: Allows for individual control of the start and stop of each assembly (such as lifting assembly 14 and rotation assembly 13), suitable for debugging or testing of special components.

[0037] Automatic mode: The single component inspection cycle can be controlled within 5-10 minutes (traditional manual loading takes 15-20 minutes), improving inspection efficiency by more than 50%.

[0038] The PLC control box component 10 has a data recording function and can store ≥1000 test records (including time, component number, and equipment parameters), which facilitates later traceability and quality analysis.

[0039] Furthermore, when using the device, the operator starts the equipment via control switch 9, the PLC control box assembly 10 is powered on and initialized, the air conditioner is powered on via air conditioner socket 12, and the internal temperature is adjusted to a suitable range in conjunction with the insulation structure of the container. The exhaust fan assembly 7 is started to maintain internal air circulation, and the roller shutter door assemblies 2 at both ends are powered via roller shutter door socket 11 and are opened according to operational needs (the front end is opened when loading, and the rear end is opened when unloading). Then, the workpiece to be inspected enters from the front roller shutter door and is sent to the feeding end of the baffle assembly 16. At this time, the baffle assembly 16 works to block the workpiece and make it stop precisely at the loading position. The PLC controls... After receiving the workpiece arrival signal, the box assembly 10 instructs the gear and rack transmission assembly 15 to start. Through the meshing of the gears and rack, the workpiece is smoothly conveyed to the detection position (above the rotation assembly 13). After the workpiece reaches the detection position, the lifting assembly 14 starts, driving the rotation assembly 13 and the workpiece to rise to the preset height (aligned with the detection head of the detection equipment). Subsequently, the rotation assembly 13 begins to work, driving the workpiece to rotate at a uniform speed, enabling the detection equipment to scan and detect the workpiece from all directions. If the detection process requires a dark environment, the lighting in the darkroom can be turned off through the darkroom switch, and the detection status can be observed through window 4. During the detection process, the PLC control box assembly 10... The system receives and processes detection data in real time to ensure that the detection process conforms to preset parameters. After the detection is completed, the self-rotating assembly 13 stops rotating, the lifting assembly 14 lowers the workpiece to the initial height, and the gear and rack transmission assembly 15 restarts, transferring the workpiece from the detection position to the discharge end of the stop assembly 17. Finally, the workpiece is sent out of the chamber through the rear roller shutter door. At the same time, the stop assembly 16 resets, waiting for the next workpiece to enter. If an emergency occurs during the detection process (such as equipment failure or workpiece position deviation), the operator can trigger an emergency stop via control switch 9. The PLC control box assembly 10 immediately commands all moving parts to stop working. In case of power failure, emergency... The lighting assembly 8 starts automatically to ensure internal lighting. During routine maintenance, the chamber can be moved via the lifting lug 3, and internal components can be inspected through the window 4. Lubricant can be added to the guide rails, racks, and other parts of the gear and rack transmission assembly 15 to ensure long-term stable operation of the equipment. In this way, the PLC control box assembly 10 acts as the core, coordinating the orderly linkage of the self-rotation assembly 13, lifting assembly 14, gear and rack transmission assembly 15, and other actuators. Together with the material blocking assemblies 16 and 17, it achieves precise positioning and conveying of workpieces. Combined with the roller shutter assembly 2, air conditioning, exhaust fans, etc., it ensures a stable testing environment, ultimately achieving automated and high-precision non-destructive testing operations.

[0040] Through the coordinated operation of the gear and rack transmission assembly 15, the stop assembly 16, and the feeding mechanism 17, the fully automatic conveying of the workpiece from the feeding end to the inspection position and then to the discharge end is realized: after the workpiece enters, it is precisely positioned by the stop assembly 16, and the gear and rack transmission assembly 15 sends the workpiece to the inspection position through smooth meshing transmission. After the inspection is completed, it is automatically conveyed to the discharge port. The entire process does not require manual handling, which not only reduces the physical exertion of workers, but also reduces the occupational health risks such as muscle strain caused by long-term lifting, freeing workers from heavy physical labor and allowing them to concentrate on inspection monitoring and equipment maintenance.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
