Description

Technical Field

[0001] This invention relates to the field of intelligent debugging platform technology, specifically to an integrated intelligent debugging platform and debugging method for molten iron traction vehicles. Background Technology

[0002] As the intelligent tractor market gradually expands, the number of intelligent tractors continues to increase. Different usage conditions place different requirements on the power supply method, operation mode, and control system of the tractor. The experimental debugging control motherboard of the tractor needs to be modified according to the different control system composition and requirements, which cannot meet the conditions for rapid simulation testing of on-site equipment failure. Modifying the circuitry of the experimental debugging control motherboard requires a high level of technical expertise and necessitates personnel with extensive knowledge of the on-site equipment to recreate the experimental conditions. Each test involves a large workload, a cumbersome process, and is prone to errors, failing to accurately simulate the actual operating conditions of the on-site equipment and hindering the rapid detection and resolution of faults. Therefore, a comprehensive intelligent debugging platform is needed to simulate the molten iron traction car, simplifying the debugging and preparation process. This platform enables rapid simulation of traction car configurations for different projects, simulating all functions and faults of the intelligent traction car, and allowing for automatic cyclic testing of the traction car control functions. It also performs stability testing of the control system and generates test records. The intelligent experimental operation platform uses a Siemens S7-1200 PLC as the main controller, paired with a large-size HMI interface. The interface is simple and clear. Through remote I / O modules, the platform can acquire the output control signals of the traction car control system, simulate remote control system signals, and simulate the feedback signals of the traction car control system according to the experimental system settings. The test platform allows users to set the on / off conditions of all feedback signals from the traction car control system via buttons, simulating equipment faults. By setting parameters, the intelligent experimental operation platform can automatically output simulated signals, simplifying debugging experiments. The integrated intelligent test bench for tractors uses a main control PLC to automatically simulate control signals and faults in the tractor control system. It can automatically and cyclically simulate operator commands and fault signal states according to the test program settings, recording the commands and fault codes, even without human intervention. This provides more detailed and accurate testing of the tractor control system, resolving the problem of easily overlooked items during human testing.

[0003] While existing integrated intelligent debugging platforms meet user needs to a certain extent, they still have certain shortcomings. Specifically, traditional debugging platforms lack dedicated and convenient cleaning components. To clean dust, iron filings, and oil stains on the screen surface, external cloths and paper towels are required, which can easily scratch the screen coating. For some debugging platforms with cleaning functions, the cleaning components are often integrated and fixed structures, requiring the removal of screws and disassembly of components to replace the cleaning cotton. Furthermore, the lighting environment in molten iron cutting workshops is complex, with both strong overhead lighting and high-temperature radiation from molten iron transportation. Traditional debugging platform screens lack dedicated light-blocking structures, resulting in severe glare when strong light shines directly on the screen, causing the displayed parameters to be blurry. Operators must frequently adjust their standing position and squint to barely read the parameters, increasing visual fatigue. Therefore, this invention designs an integrated intelligent debugging platform and debugging method for molten iron traction vehicles to solve the above problems. Summary of the Invention

[0004] This invention provides an integrated intelligent debugging platform and method for molten iron traction vehicles, effectively addressing the issues raised in the background section. Traditional debugging platforms lack dedicated and convenient cleaning components, requiring external tools such as cloths and tissues to clean dust, iron filings, and oil stains from the screen surface, which can easily scratch the screen coating. Some debugging platforms with cleaning functions have integrated, fixed cleaning components, requiring screw removal and component disassembly for cleaning cotton replacement. Furthermore, the complex lighting environment in molten iron cutting workshops, with both strong overhead lighting and high-temperature radiation from molten iron transportation, means traditional debugging platforms lack dedicated light-blocking structures. Direct sunlight on the screen causes severe glare, resulting in blurred parameters. Operators must frequently adjust their standing position and squint to barely read the parameters, increasing visual fatigue.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, comprising a debugging platform base, wherein connection ports are uniformly opened on the top surface of the debugging platform base, buttons are provided on the top of the debugging platform base, and a screen is provided on the top of the debugging platform base; The top of the debugging platform base is equipped with a sliding protective frame, a rotatable cleaning cotton for cleaning the screen, and a light-blocking plate that can be adjusted and rotated at multiple angles.

[0006] A comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, preferably wherein electric telescopic rods are installed at both ends of the platform base by screws, and the bottoms of the two electric telescopic rods are connected by screw lifting plates.

[0007] A comprehensive intelligent debugging platform and debugging method for molten iron traction cars, preferably wherein spring telescopic rods are uniformly installed on the top surface of the platform base by screws, and a sealing plate is installed on one end of each spring telescopic rod by screws, wherein the sealing plate corresponds one-to-one with the connection port, and the inner diameter of the connection port is smaller than the outer diameter of the sealing plate.

[0008] A comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, preferably, has movable slots at both ends of the top of the debugging platform base, a protective frame is slidably connected inside the movable slots, and a baffle is fixedly connected to one end of the top of the debugging platform base.

[0009] A comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, preferably wherein the bottom of the protective frame is T-shaped to avoid the problem of the protective frame falling off, and the protective frame is located on top of the buttons.

[0010] A comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, preferably, wherein a spring telescopic column is provided on the top of the debugging platform base, an installation plate is installed at one end of the spring telescopic column by screws, a slot is opened at one end of the installation plate, an insertion plate is slidably connected inside the slot, a cleaning cotton is glued to one end of the insertion plate, a storage frame is provided on the top of the debugging platform base, a rotating block is rotatably connected to one end of the installation plate, a limit plate is fixedly connected to one end of the rotating block, and a rubber plate is glued to one end of the limit plate.

[0011] A comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, preferably wherein one end of the insertion plate is convex and the insertion plate at the convex end is located inside the slot.

[0012] A comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, wherein preferably, the insertion plate can be placed inside the storage frame, and the end face of the rubber plate is in contact with the end face of the insertion plate.

[0013] A comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, preferably, has a rotating block rotatably connected inside the top of the base of the debugging platform, a rubber frame bonded to the outside of the rotating block, an installation block fixedly connected to one end of the rotating block, a rotating shaft rotatably connected to one end of the installation block, and a light-blocking plate fixedly sleeved on the outside of the rotating shaft.

[0014] A comprehensive intelligent debugging platform and debugging method for molten iron traction vehicles, wherein preferably, the light-blocking plate is located at one end of the screen.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. The electric telescopic rods at both ends of the base of the test bench can drive the lifting plate to rise and fall. When personnel stand on the lifting plate, they can adjust the height of the lifting plate according to their own height to make the operating posture more comfortable. They can conveniently operate the buttons and observe the screen without bending over or tiptoeing, reducing fatigue during long-term operation and improving debugging efficiency and operational safety. The insertion plate can slide along the mounting plate slot. With the help of the rotating block and the limiting plate, the cleaning cotton can be quickly removed and replaced without tools. When cleaning, the insertion plate can be rotated to make the cleaning cotton fit the screen. After cleaning, the insertion plate can be rotated to store it in the storage box, avoiding contamination and loss. This greatly simplifies cleaning and maintenance operations and improves maintenance efficiency. The rotating block can drive the light-blocking plate to rotate horizontally from 0 to 180° around the base of the test bench, precisely aligning it with the direction of the strong light source; the rotating shaft can drive the light-blocking plate to tilt from 0 to 90°, ensuring that the light-blocking plate completely blocks the strong light without affecting the operator's observation of the screen. At the same time, the rubber frame bonded to the outside of the rotating block can increase the rotational resistance, keeping the light-blocking plate fixed after adjustment and preventing it from shifting due to workshop vibration. The test bench is designed with a closed protective structure corresponding to each connection port. Each connection port is equipped with an independent spring telescopic rod and a sealing plate. When the connection port is not in use, the spring telescopic rod extends naturally, pushing the sealing plate upward to completely cover the connection port, forming a physical barrier to effectively prevent dust, iron filings, and oil from entering the interface. The top of the test bench is designed with a sliding protective frame. The bottom of the protective frame adopts a T-shaped structure, which precisely matches the moving groove of the test bench base. The sliding process is stable without shaking or jamming. When the equipment is idle or the buttons do not need to be operated, the protective frame can be pushed along the moving groove to completely cover the button area, forming a physical protective barrier and effectively preventing the problem of accidental button touch during personnel movement and tool handling. This testing platform is not merely a single-function optimization, but rather an organic integration of functions such as height adjustment, cleaning and maintenance, interface protection, button protection, and screen light blocking, forming a complete functional system. Each functional component operates independently yet collaboratively. For example, the height adjustment function provides operators with a comfortable operating posture, while the screen light blocking function ensures clear parameter reading; interface and button protection functions guarantee safe and stable equipment operation, and the cleaning and maintenance function reduces equipment failure rates and maintenance costs. This integrated design allows the testing platform to adapt to the complex environment and diverse testing needs of the molten iron workshop, not only improving the practicality and reliability of individual devices but also providing a standardized and efficient solution for molten iron traction vehicle testing operations, thus contributing to improving the overall testing operation level and production efficiency of the enterprise.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example: Figure 1-5 As shown, the present invention provides a technical solution, a comprehensive intelligent debugging platform and debugging method for molten iron traction cars, including a debugging platform base 1, characterized in that: electric telescopic rods 2 are installed at both ends of the debugging platform base 1 by screws, and the bottoms of the two electric telescopic rods 2 are connected by screw lifting plates 3. The top surface of the test bench base 1 is evenly provided with connection ports 4, the top of the test bench base 1 is provided with buttons 5, and the top of the test bench base 1 is provided with a screen 11. The top surface of the test bench base 1 is uniformly equipped with spring telescopic rods 6 by screws. One end of the spring telescopic rod 6 is equipped with a sealing plate 7 by screws. The sealing plate 7 corresponds to the connection port 4 one by one. The inner diameter of the connection port 4 is smaller than the outer diameter of the sealing plate 7, so as to facilitate the sealing of the connection port 4.

[0020] The base of the test bench 1 has a movable groove 9 at both ends of the top. A protective frame 8 is slidably connected inside the movable groove 9. A baffle 10 is fixedly connected to one end of the top of the test bench base 1.

[0021] The bottom of the protective frame 8 is T-shaped to prevent the protective frame 8 from falling off. The protective frame 8 is located on top of the button 5, which facilitates the protection of the button 5 and prevents the button 5 from being accidentally pressed when the device is not in use.

[0022] The top of the test bench base 1 is provided with a spring telescopic column 12. One end of the spring telescopic column 12 is installed with a mounting plate 13 by screws. One end of the mounting plate 13 has a slot 14. An insertion plate 15 is slidably connected inside the slot 14. A cleaning cotton 16 is glued to one end of the insertion plate 15. The top of the test bench base 1 is provided with a storage frame 17. A rotating block 18 is rotatably connected to one end of the mounting plate 13. A limit plate 19 is fixedly connected to one end of the rotating block 18. A rubber plate 20 is glued to one end of the limit plate 19.

[0023] One end of the insertion plate 15 is convex, and the insertion plate 15 at the convex end is located inside the slot 14, which can initially limit the insertion plate 15 and prevent the insertion plate 15 from falling out.

[0024] The insertion plate 15 can be placed inside the storage frame 17. The end face of the rubber plate 20 is in contact with the end face of the insertion plate 15, which can limit the insertion plate 15 and facilitate the storage of the cleaning cotton 16.

[0025] A rotating block 21 is rotatably connected inside the top of the base 1 of the test bench. A rubber frame 22 is glued to the outside of the rotating block 21. An installation block 23 is fixedly connected to one end of the rotating block 21. A rotating shaft 24 is rotatably connected to one end of the installation block 23. A light-blocking plate 25 is fixedly sleeved on the outside of the rotating shaft 24.

[0026] The light-blocking plate 25 is located at one end of the screen 11 and can block the light from the screen 11 to avoid the problem of reflection on the screen 11.

[0027] When the connection port 4 is not in use, the spring telescopic rod 6 on the top surface of the test bench base 1 is in a naturally extended state. The spring telescopic rod 6 pushes the sealing plate 7 at one end to move upward. Since the outer diameter of the sealing plate 7 is larger than the inner diameter of the connection port 4, the sealing plate 7 completely covers the connection port 4, preventing dust, iron filings, and oil stains from entering the interior of the connection port 4, thus achieving interface protection. When connection port 4 is needed, the operator presses down on the sealing plate 7, which compresses the spring telescopic rod 6 until connection port 4 is fully exposed. After inserting the external connection cable into connection port 4, the supporting force of the connection cable keeps the sealing plate 7 in a compressed state. After the connection cable is pulled out, the spring telescopic rod 6 automatically extends, causing the sealing plate 7 to reset and re-close connection port 4. When the equipment is idle or button 5 is not required, push the protective frame 8 on the top of the test bench base 1. The protective frame 8 slides along the moving groove 9 until it completely covers the area of ​​button 5. The T-shaped structure at the bottom of the protective frame 8 is in close contact with the inner wall of the moving groove 9 to ensure that the protective frame 8 is stable and does not shake or fall off, thus avoiding accidental touch of button 5. When button 5 needs to be operated, pull the protective frame 8 towards the baffle 10. The protective frame 8 slides along the moving groove 9 to the baffle 10, completely exposing the area of ​​button 5, and personnel can operate button 5 normally for debugging. After debugging is completed, push the protective frame 8 in the opposite direction to reset it and cover button 5 again. When the screen 11 reflects light, rotate the rotating block 21 at the top of the test bench base 1. The rotating block 21 drives the outer mounting block 23 and the light-blocking plate 25 to rotate synchronously. Adjust the horizontal angle of the light-blocking plate 25 so that it is aligned with the direction of the strong light source. Rotate the rotating shaft 24 at one end of the mounting block 23. The rotating shaft 24 drives the light-blocking plate 25 to rotate. Adjust the tilt angle of the light-blocking plate 25 to ensure that the light-blocking plate 25 completely blocks the strong light and does not affect the personnel's observation of the screen 11. The rubber frame 22 on the outside of the rotating block 21 increases the friction to keep the rotating block 21 fixed after adjustment and prevent the light-blocking plate 25 from shifting due to vibration. When the screen 11 area of ​​the test bench needs to be cleaned, the personnel rotate the insertion plate 15 to rotate the cleaning cotton 16, thereby cleaning the screen 11. After cleaning, the cleaning cotton 16 can be rotated into the storage box 17 for protection. When the personnel need to replace the cleaning cotton 16, they rotate the limiting plate 19 to prevent it from contacting the insertion plate 15. Then, the personnel can replace the cleaning cotton 16 by moving the insertion plate 15. This facilitates the installation and removal of the cleaning cotton 16 and the cleaning of the screen 11, improving the efficiency of screen cleaning.

[0028] When using the test bench base 1, the personnel stand on top of the lifting plate 3 and adjust the height of the lifting plate 3 by activating the electric telescopic rod 2. This makes the test bench base 1 suitable for personnel of different heights, reducing the labor intensity of personnel using the test bench base 1.

[0029] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
