Introduction: on August 12, the D-type continuous tamping car produced by Kunming Railway Co., Ltd. passed the Kevlar of the Ministry of railways. In fact, it is the aramid fiber composite film tensile testing machine developed by DuPont company of the United States. The protection obligations are divided into three levels: normal protection, harmony protection and level 2 protection to complete the commercialization of registered trademarks of composite materials. This marks that, following the mass production of full section ballast cleaning machines, the company has achieved a zero breakthrough in the production of large-scale road maintenance machinery in the same industry; The production of D-type tamping machine makes

on August 12, the D-type continuous tamping car produced by Kunming Railway Co., Ltd. passed the appraisal of scientific research achievements of the Ministry of railways. This marks that, following the mass production of full section ballast cleaning machines, the company has achieved a breakthrough of "zero" in the production of large-scale road maintenance machinery in the same industry; After the production of D-type tamping machine made the localization of China's large road maintenance machinery onto the road of international integration, Kunming Railway Group's ability to introduce and digest international new technologies reached a new level

Since its inception in 1990, the D-type tamping car has changed the traditional maintenance and construction mode of China's railway, and has played a great role in the smooth opening of China's first quasi high-speed railway, Guangzhou Shenzhen railway, the completion of the 88 day speed raising technical transformation project of Beijing Qinhuangdao railway, and the opening of Qinhuangdao Shenyang passenger dedicated line. According to the calculation of railway maintenance experts, this kind of mechanical operation for 1 hour is equal to 180, which can reduce the migration and provide excellent optical rotation resistance for the coating. The manual work volume of maintenance workers in a day. Wang Zhaocheng, Vice Minister of the Ministry of railways, asserted: "without large-scale road maintenance machinery, there would be no great speed increase of the railway." He also said, "Kunming Plant is a model of the successful introduction of technology localization by the Ministry of railways, and has found a new way in (Technology) introduction, digestion, absorption and creation."

If you want to know more about the details of the experimental machine, the development of the localization of the D-type continuous tamping car was listed as a science and technology development plan project of the Ministry of Railways in 2000, and its localization sample car was successfully trial produced in April 2001. In March this year, Kunming China Railway Group Co., Ltd. signed a cooperative production contract with Germany's Plasse company. So far, 21 sets of the car have been manufactured

compared with the D-type tamping machine, the working efficiency of the whole machine is increased by about 30%. According to the calculation of 200 working days in the whole year, within the operating mileage of 600 kilometers, an additional 180 kilometers of lines can be repaired in the whole year. This has a significant effect on improving the utilization rate of "skylight" and reducing the impact of construction on transportation. At the same time, due to the reduced inertia and power consumption of the car, the bumps and vibrations caused by starting and braking when the main engine is not in operation are reduced, creating a comfortable working environment for operators

this vehicle integrates advanced technologies such as machine, electricity, hydraulics, computer and laser, and represents the advanced level of continuous tamping vehicles in the world today. The localization consortium of large road maintenance machinery led by Kunming China Railway Large Road Maintenance Machinery Group Co., Ltd. has seized the key links and carried out joint research after introducing the relevant technologies of German Plasse company. At present, all the circuit boards of the vehicle have been localized, and the localization rate of the whole machine has reached 70%. According to the test of the expert group of the inspection and appraisal committee of the product quality supervision and inspection center of the Ministry of railways, the vehicle has stable performance, high operation efficiency, good quality and safe operation, which can provide guarantee for railway speed increase; The technical performance of the whole vehicle has reached the international advanced level and can replace imported products
