Safety standards and regulatory requirements of train locks
I. Introduction
With the development of society and the progress of science and technology, railway transportation plays an increasingly important role in people's lives. In order to ensure the safety of passengers' lives and property, it is necessary to strictly abide by the relevant safety standards and regulations during the manufacturing process of trains. Among them, the train lock is one of the important security facilities, and its design, production, installation and other aspects must meet the relevant regulations formulated by the state.
Second, the importance and function of train locks
Train lock is one of the key components to ensure the safe operation of the train, which mainly includes car door lock, window lock and some special-purpose locks. It can not only effectively prevent illegal invasion by outsiders, but also ensure the personal safety of passengers. In addition, in an emergency, qualified train locks can also provide convenient conditions for rescue work.
Third, the current regulations and standards
1. People's Republic of China (PRC) Law on Safety in Production: It is clearly stipulated that enterprises must design and develop products according to relevant national or industrial standards, and regularly inspect and maintain equipment.
2. GB/T 369472018 Rail Transit Equipment Mechanical connectors and accessories for trains Part 4: Electrical/pneumatic connectors: technical parameters and test methods of various connectors on trains are specified in detail;
3. TB/T 23772014 General technical conditions for railway passenger car parts Part 3: Door locking devices: The design principles and material selection requirements of various door locking devices are specified in detail;
4. ISO 167504:2017(E) Road vehicles-Environmental conditions and test procedures Part 4: Climatic load of electrical/electronic components: Although it is not a standard specially set for the train field, it will also be referred to in some specific situations.
Fourth, the practical application case analysis
Take an accident as an example, because a window in a carriage was not completely closed and locked, a child accidentally put his hand out of the window and suffered injuries. After the investigation, it was found that the window lock had obvious defects-it could be easily opened even if a certain force was applied from the outside. This obviously violates the provisions of TB/T 23772014 that such products should have sufficient strength. Therefore, the manufacturers involved should bear corresponding responsibilities and conduct comprehensive investigation and rectification of similar products.
V. Summary
In a word, train locks, as a vital safety protection measure for vehicles, need to be operated and implemented in strict accordance with existing laws and regulations and various technical indicators, both in the design stage and in the subsequent use and maintenance process, so as to minimize the accident rate and protect the interests of the broad masses of people from damage. At the same time, government departments should also strengthen supervision, update and improve relevant system norms in time, and jointly promote the healthy and stable development of the whole industry!
