Railway equipment is mostly placed in open air and easily interfered by external interference. In particular, for power supply catenary equipment, after external interference, it will cause tripping power failure, affecting the normal operation of the train.
Recently, due to strong wind weather kites, balloons, lights, color steel tiles, plastic cloth and other low-altitude hanging (floating) objects scraped to the railway power supply, seriously endangering railway transport safety.
In order to maintain the safety of railway transport, the relevant departments have organized many special rectification actions to investigate the hidden dangers of light hanging objects along the railway line in a network-pull manner, and the staff have removed the floating (floating) objects on the railway.
Among them, the most common is manual cleaning, and it is well-known that the cost of manual cleaning is very high, and it takes a long time and has a greater risk; while operation in railway areas is accompanied by a higher risk.
Therefore, more advanced laser techniques for removing foreign bodies have also been gradually applied.
It is understood that as early as December 2020, China Railway Jinan Group held procurement project bidding, the "distant laser melting instrument" was emerged, that is "laser obstacle remover", "laser foreign body removal instrument." This product is used for removing hanging objects from overhead lines and high-voltage lines in railway zones.
It is believed that the maintenance of railway equipment will become more and more convenient and train travel will be more safe under the addition of advanced technology.
SPT laser obstacle remover can be used for railway obstacle removal
However, in general, special rectification and regular cleaning can only cure symptoms, only through the participation of the whole people, can the root cause be treated.
We can start from ourselves and not raise kites, balloons and other low-altitude hanging objects within 500 meters on both sides of the railway power supply catenary; units and individuals such as plantations, garbage dumps, and construction along the railway line shall timely clean up hanging objects such as plastic cloth and reflective film and jointly maintain railway transportation safety.
