"It takes about 4 hours for a train made up of more than 50 C80 cars to be repaired in condition, which is 68 hours less than the traditional 'scheduled repair'!" Not long ago, in the Huanghua port, Cangzhou City, the National Energy Group intelligent operation and maintenance "condition repair" line of the field, the relevant professionals told us so.
Status repair, this is praised by relevant experts in the industry as creating a new model and new method for overhaul of new railway heavy haul truck in our country. It blooming charm on more than 2400 kilometers of heavy haul railway line run by national energy group, but also shows the spirit of brave struggle and fearless innovation of railway workers, to make tight time and heavy task heavy haul railway freight more safe And run efficiently.
Precious energy, safety first, heavy haul railway freight shouldering the national energy development strategy burden.
Intelligent diagnosis accurate repair
"Car number 0043153; Model C80; Predicted repair Z1 repair; Bus No. 8269; Its mileage is 1,913,500......" In the intelligent operation and maintenance "condition repair" maintenance line vehicle condition repair monitoring and warning room, click the mouse, the large electronic screen appears the operation status of heavy trucks.
The state monitoring system of National Energy railway equipment freight car is a "good doctor" to realize the safe operation of heavy-duty freight car. Through scientific pulse diagnosis -- early warning monitoring, issuing vehicle diagnosis report, where there is a fault repair. The accuracy of early warning and monitoring is high, the vehicle can accurately detect any "disease", and promptly notify maintenance, enter the Huanghua Port of rectification line, accurate treatment and maintenance.Compared with the traditional "planned repair" mode, the intelligent operation and maintenance "State Z1 repair" is mainly aimed at the condition that the brake shoe of the whole train wears out to the limit. The average daily number of trains is 4, and the repair time of each train is controlled within 4 hours. The maintenance cost of each train in the whole life cycle of railway freight car is reduced by at least 20%.
It is understood that the state repair is divided into four repair grades: Z1, Z2, Z3 and Z4. The state repair of Z2, Z3 and Z4 mainly focuses on the wear limit of some key parts such as axle, hook tongue and brake valve, the life of key parts expires, and the inspection and maintenance of the life of major large parts of the whole train and the expiry of the inspection and maintenance.
In recent years, more than 50,000 heavy-duty trucks of the National Energy Group have exceeded the operating standards of the national railway heavy-duty trucks, with an average running speed of 80 kilometers per hour in 10,000-ton transport models. In operation, it has set a record of more than 30 consecutive days without withholding the car for repair, bringing a very good transportation environment. "Dozens of days without impoundment of the car is rare in the history of heavy truck operation, compared with the past, there is a cliff type fall, to the greatest extent to ensure the smooth flow of railway transportation, alleviate the contradiction between transportation and maintenance, which is the state repair intelligent diagnosis, accurate repair benefits."
To avoid the hidden danger of safety, waste costs, improve efficiency, in front of the era of opportunities of the country vigorously promoting the construction of intelligent railway, national energy railway equipment company to seize the opportunity, and make breakthroughs in the tradition of the accumulation of technological innovation strength and technical personnel advantages, successfully created the first heavy duty railway truck intelligent operation and maintenance line in our country railway industry, established the status Repair technical standard system, the heavy-duty railway freight cars into the era of intelligent operation and maintenance, improve the maintenance efficiency and accuracy of railway freight cars, and create huge economic benefits.
Ensure sustained energy innovation
National energy supply work is related to the lifeline of national economic construction. National road traffic construction, smart railway construction, and supply-side reform are all important strategic deployment to promote national economic development and construction. The macro blueprint from the top-level design is drawn. The National energy railway equipment company, which is responsible for the operation and maintenance of heavy haul railway equipment, is in harmony with the national strategy The pattern.
Guoneng Railway Equipment Co., Ltd. is a wholly-owned subsidiary of National Energy Group. It has been committed to breaking through the reform of the traditional planned repair system and exploring a new maintenance mode that can make maintenance decisions intelligently by judging the health status of railway freight cars.
For a long time, the overhaul mode of railway truck in our country generally exists the phenomenon of "no disease and also cure" and "cure disease", wasting cost, delaying time, especially for the increasing of 10,000 tons heavy haul transportation, because of the high turnover frequency, aggravating abrasion, the unification of repair according to the time cycle, leading to the vehicle "running with disease", even causing hidden danger of operation safety. At present, the state repair line of National Energy Group at Huanghua Port in Cangzhou is not only advanced and complete in equipment, so as to realize accurate fault positioning, rapid maintenance and batch replacement of parts, so as to handle faults more thoroughly. At the same time, it is equipped with the innovative achievements and technical product "intelligent inspection robot" developed by National Energy Group jointly with multiple scientific and technological research and development forces, which has been completely developed since its application Tianhou 24-hour operation, in the case of high intensity, large amount of work, instead of manual accurate judgment, accurate repair, improve the efficiency and intelligent level, reduce the labor intensity of workers, reduce the cost of input.
< /p>Up to May this year, Guoneng Railway Equipment Company has declared more than 100 patents, and invented important academic papers and published monographs. In order to better promote the extensive and in-depth development of "condition repair" work, since last year, it has completed the installation and deployment of self-powered Beidou positioning terminals on hundreds of main models, realized the real-time positioning tracking and accurate mileage calculation of all "condition repair" trains, and supplemented and improved the basic railway GIS data of the Group, which marks the pilot project of building a national energy group into a transportation power The project achieved phased results.
