Description
Technical Field
[0001] The present application relates to the technical field of railway vehicle couplers, and in particular to a coupler air duct protection device. Background Art
[0002] As one of the core components of railway vehicles, the coupler is responsible for the traction and coupling between adjacent vehicles, and is a key component to ensure the stable operation of trains and the comfort of passengers. The main function of the coupler is to reduce the longitudinal impact force between trains by tightly connecting adjacent vehicles, thereby avoiding severe impact and shaking between vehicles, ensuring the stability of the train during operation, and improving the passenger experience. At the same time, the coupler also needs to have strong tensile and compressive resistance to ensure the safety of the train in complex operating environments.
[0003] During the vehicle manufacturing process, especially before the coupler is connected, the air duct opening of the coupler is usually exposed and easily affected by the external environment. In order to prevent the air duct opening from being contaminated, water ingress or interference from debris, temporary protective materials such as paper tape are usually used to wrap the air duct opening of the coupler. However, the protective material of the paper tape is relatively fragile and can be easily damaged or fall off during transportation, scheduling and assembly. This leads to the problem of the air duct opening of the coupler being exposed during vehicle transportation, and repeated inspections and reinstallation of protective materials are often required.
[0004] Since the coupler is located at the bottom of the vehicle after installation, the operating space is small and the coupler is located at a low position. When rearranging the protective materials manually, there will be great space restrictions, making the operation process cumbersome and inefficient. Especially during the production and transportation of vehicles, the staff must frequently check whether the air duct opening is damaged and whether the protective materials have fallen off. If the protection is not in place, the air duct opening may be affected by water or debris intrusion, affecting the normal use of the coupler and the performance of the equipment. In addition, frequent replacement and inspection of protective materials will increase labor costs and material waste, affecting the overall production progress and efficiency.
[0005] Therefore, there is an urgent need for a more efficient, stable and convenient solution to improve the protective effect of the coupler air duct opening, reduce the complexity of manual operation, reduce production costs and improve work efficiency. Summary of the invention

The end of the spring 3 away from the fixed rod 9 is connected to the movable card 2. The spring 3 is used to control the position of the movable card 2 and to tighten the movable card 2. During the actual installation process, the tightening effect of the spring 3 ensures the stable position of the movable card 2 to prevent it from loosening or falling off during use. Through the torque of the spring 3, the movable card 2 always remains in a tightened state, thereby providing an effective sealing function.
[0037] A guide limit portion 10 is provided on the first protective plug 1, and the movable card 2 is inserted into the guide limit portion 10 and slides in the guide limit portion 10; the design of the guide limit portion 10 can prevent the movable card 2 from tilting or irregularly displacing during the movement, thereby avoiding failure or loosening of the card due to uneven sliding, providing a more reliable locking function, and ensuring the sealing performance of the first protective plug 1 and the second protective plug 4.
[0038] The movable card 2 includes a connecting portion 21 and a clamping plate portion 22. One end of the connecting portion 21 is connected to the spring 3, and the other end passes through the guide limiting portion 10 to be connected to the clamping plate portion 22. The clamping plate portion 22 is provided with a clamping groove 23, and is clamped and fixed with the coupler 7 through the clamping groove 23; the connecting portion is located at one end of the movable card 2, and is connected to the spring 3 through the end, and it plays a role in transmitting the force of the spring 3 to the movable card 2, ensuring that the movable card 2 can slide along the guide limiting portion 10 when needed; the clamping plate portion 22 is clamped and fixed with the coupler 7 through the clamping groove 23, ensuring that the coupler 7 can be firmly combined with the movable card 2 to form a stable clamping structure, and a firm connection is formed between the movable card 2 and the coupler 7, thereby ensuring the stability of the coupler 7.
[0039] The connecting portion 21 and the clamping plate portion 22 form a T-shaped structure; through the T-shaped structure design, the force of the connecting portion 21 and the clamping plate portion 22 is distributed at right angles, which can increase the stability of the overall structure and avoid distortion or displacement between the clamping plate portion 22 and the connecting portion 21; the T-shaped structure provides good rigidity and stability, especially when bearing lateral and vertical loads, the lateral distribution of the clamping plate portion 22 helps to disperse the force during clamping and avoid damage to the clamp due to excessive local stress.
[0040] In this embodiment, the fixed card 5, the movable card 2, the connecting rod 6, the fixed rod 9, and the spring 3 are made of stainless steel; since stainless steel has excellent corrosion resistance, wear resistance and strength, the entire device can be used for a long time in harsh environments, reducing the need for frequent replacement and maintenance; the use of stainless steel components and the strength and toughness of each component ensure the stability of the entire device in dynamic environments such as the coupler 7, and will not be damaged or lose function due to factors such as vibration and impact.

Specifically, the card plate portion 22 of the movable card 2 is pulled upward, and the connecting portion 21 of the movable card 2 moves in the guide limiting portion 10 of the first protective plug 1. At this time, the guide limiting portion 10 can limit the movement trajectory of the entire movable card 2, and the card slot 23 of the card plate portion 22 of the movable card 2 is stuck into the upper side of the coupler 7. At this time, the tension of the spring 3 can ensure that the movable card 2 moves toward the upper side of the coupler 7, and ensure that the movable card 2 is tightly engaged with the upper side of the coupler 7, completing the installation and fixation of the entire device. In this process, the tensioning effect of the spring 3 ensures the stable position of the movable card 2 to prevent it from loosening or falling off during use.
