Domestic advanced track maintenance equipment guarantees the construction quality of China Laos railway

In the construction project of the China Laos Railway, the domestic equipment was put into construction simultaneously in the Yuxi Mohan section in China and the Boten Vientiane section abroad, so as to build a high-quality railway with "intelligent manufacturing in China".

Wuhan large-scale road maintenance machinery application and maintenance section to tackle the problem of centralized repair of Jiaozhou-Liuzhou Railway

As of March 15, the Wuhan large maintenance machinery operation and maintenance section has completed the overhaul and replacement of 5000 sleepers, the screen cleaning operation of 17.4 kilometers, the line tamping of 103 kilometers, the line grinding of 5 kilometers, the turnout tamping of 135.5 groups, and the turnout grinding of 4 groups. At present, the construction progress is orderly, safe and controllable. It is expected that the first phase of centralized repair of Jiaozhou-Liuzhou Line will be completed before April 2. After the centralized repair of Jiaozhou-Liuzhou Line, the line equipment diseases will be removed and the equipment quality will be greatly improved.

Maintenance mechanical vehicle

On February 17, the staff of the Hohhot track maintenance machinery section of China Railway Hohhot Bureau were repairing the large road maintenance machinery car. In order to meet the upcoming centralized repair of Tangbao Line, the Hohhot track maintenance machinery section made every effort to improve the quality of mechanical equipment, focusing on the maintenance of running, hydraulic and other system components to ensure the normal operation of mechanical vehicles.

67! Annual repair of large road maintenance machinery

The section plans to complete the delivery and inspection of large locomotives within two months, and carry out inspection, disassembly, flaw detection, repair, assembly, test and other work on 14 system assemblies and components including coupler device, power transmission system, braking system, body structure and working device of each large locomotive. In order to complete the summer annual repair task on schedule, each workshop arranged the construction period backward, formulated a detailed maintenance plan, organized the division of labor according to the principle of "fixed person and fixed project", achieved orderly production organization, steadily improved the completion rate, and effectively promoted the maintenance progress.

Jiaoguang Reception Hall | Summer maintenance, "strengthen the body" for mechanical vehicles

It is understood that this summer's maintenance work began in the middle of July, and the large road maintenance machinery vehicles that passed the acceptance will immediately "rush" to the next operation site, continue to remove the "disease" of the line, improve the overall passenger and cargo transport capacity of the line, and escort passengers to travel safely.

"Physical examination" of mechanical equipment to ensure smooth Spring Festival transportation

In the face of the busy Spring Festival transportation, the maintenance personnel said confidently: "We will do a good job in the maintenance of large-scale road maintenance machinery, maintain the line well, and ensure the safety of train operation during the Spring Festival transportation."

Delivery of 10 mainline highway maintenance machinery and equipment

It is reported that in recent years, the maintenance of the national and provincial trunk roads in Ankang City is mainly manual. The mechanical equipment is relatively old and backward, and the degree of mechanization is not high. With the aging of the front-line maintenance workers, it is urgent to promote mechanized maintenance. To this end, Ankang Municipal Highway Bureau adopted the mode of "enterprise purchase, maintenance unit rental", organized the engineering department, emergency rescue center, and machine repair plant to invest 6.9 million yuan to purchase 3 road sweepers and 7 sprinklers, which were leased to 8 local highway sections with use needs, for road cleaning, road environmental improvement, etc., to improve the comprehensive quality and efficiency of national and provincial trunk line maintenance It is of great practical significance to promote the expansion, quality and efficiency of enterprises.

Lanzhou "repair the old and reuse the old" road maintenance machinery: iron pimples are rejuvenated, saving more than one million yuan

"Through this way of recycling, the cost of small machinery maintenance this year will be saved by another 200000 yuan on the basis of last year." Li Chengguo said that since 2019, on the basis of not affecting production, this section has achieved a savings of 1.48 million yuan through four consecutive years of recycling. In recent years, the Lanzhou West Works Section of China Railway Lanzhou Bureau Group Co., Ltd. has vigorously promoted the repair and recycling of the old and the waste, saving costs and reducing consumption, and adhered to the idea of "repair without discarding, use without replacement" and "supply according to demand, self-reliance and self-sufficiency". According to the characteristics of on-site production and the actual situation of equipment, it has realized the sharing of technology and resources, and turned the abandoned "iron knot" into a useful "gold knot".

"Discover the most beautiful railway" heavy equipment to see how the large-scale railway maintenance machinery works in an integrated way

Subsequently, QS-650 full-section ballast cleaning and screening truck is the main force of mechanized ballast cleaning and screening, which plays an important role in improving the efficiency of large machines. It can cut the ballast on the track bed with the finger of the excavation chain, and carry out the vibration screening of the ballast, which can complete the ballast excavation, ballast screening, ballast backfilling and waste soil throwing at one time. It is called the "physician" of the line, and the ballast cleanliness after cleaning can reach more than 97%. The WY-100 material transport vehicle, which cooperates with the cleaning and screening truck, is mainly used for the storage, transportation and transportation of ballast or waste soil. The single vehicle can load 68 cubic meters, changing the situation that the waste is carried by hand.
