Daily maintenance and overhaul of train locks
Train lock is one of the important components to ensure the safety of railway transportation, which plays an important role in ensuring the safety of passengers' lives and property and the normal operation of trains. Starting with the basic concept of train lock, this paper discusses the importance of its daily maintenance and overhaul, and puts forward specific measures.
First, the concept and function of train lock
Train lock refers to a safety device used to lock doors, carriages and other parts to prevent casualties or loss of goods due to accidents. It is usually composed of lock body, key and fixed parts, and is divided into two categories: manual lock and automatic lock, in which manual lock is mainly used for the side door of passenger cars and trucks; The automatic lock is mainly used in the internal door and window control system of EMU. No matter what type, it needs regular inspection and maintenance to ensure its stable and reliable performance.
Second, the daily maintenance of train locks
1. Regular cleaning: use a soft cloth dipped in a proper amount of detergent to wipe the dust and stains on the surface to avoid affecting the aesthetics; At the same time, clean up the internal dust impurities to keep the lubrication between parts smooth;
2. Check the fasteners: check whether the screws are loose and fall off, and tighten them in time for reinforcement; If any missing condition is found, the installation shall be supplemented immediately to prevent potential safety hazards.
3. Add lubricating oil: add proper amount of rust-proof grease to the moving parts to improve wear resistance and corrosion resistance;
4. Replace damaged parts: If there are problems such as wear and deformation, you need to buy new products of corresponding models as soon as possible to replace them.
Third, the train lock troubleshooting methods
1. Unable to open and close: firstly, determine whether the power supply is electrified well, and secondly, observe whether there are foreign objects stuck in the transmission mechanism, and tap to remove obstacles; Then confirm whether the electronic control panel is working abnormally, and solve the problem by replacing the battery or resetting the parameters;
2. The lock cylinder does not rotate flexibly: remove the shell to check the meshing state of the internal gear, and repair and replace it in time if it is damaged; A small amount of graphite powder can also be injected into the lock hole to increase friction;
3. Difficult key insertion and removal: first, gently polish the contact surface with fine sandpaper to remove burrs, and then coat it with a wax protective layer to return to normal.
IV. Conclusion
In short, attention should be paid to the maintenance and management of train locks in daily work, and effective measures should be taken to prevent the occurrence of various bad conditions, so as to provide people with more comfortable and comfortable service experience. I hope this article can help you understand the relevant knowledge and jointly promote the development of China's railway industry to a higher level!
