Under the background of China's economic development in “new normal” and the promotion of the Belt and Road Initiative, the bulk material logistics and transportation demand of single wagon double open top container is accelerating. The existing loading technology can only meet the requirements of single container, cannot realize the continuous and efficient loading of single wagon double container. The two containers are usually placed unevenly, which also brings great difficulties to container loading. In order to solve the above problems, taking coal container loading as an example, according to the actual loading demand of 6500 t/h, the rapid quantitative loading scheme of containers is deeply analyzed, and the scheme of single set and double warehouse rapid quantitative loading system is finally determined, and a new technology of double warehouse cooperative asynchronous loading is proposed, which solves the problem that single wagon double container cannot be continuously loaded. The loading efficiency is greatly improved, and the loading quality is guaranteed. The engineering practice shows that the rapid quantitative loading system of bulk container realizes the automation and intelligence of the rapid quantitative loading process of container, and the maximum loading capacity can reach 7200 t/h. The research results are of great significance to the development of railway container multimodal transport, the promotion of railway supply-side structural reform, and the promotion of green and low-carbon development of integrated transportation.
