Description

Technical Field

[0001] The present invention belongs to the technical field of railway transport vehicles, and particularly relates to a car body and a vehicle for transporting containers on a metre-gauge railway. Background Art

[0002] A metre-gauge railway, also known as a "narrow-gauge railway" with a gauge of 1 metre (1000 millimetres), is still used in many regions and countries around the world, especially in countries or regions such as France, Yunnan in China, Vietnam, Myanmar, and Malaysia. Due to its smaller gauge, this form of railway has unique transportation advantages in mountainous areas, hilly areas, and space-constrained areas within cities. In China, the research and development of special vehicles for transporting containers on metre-gauge railways mainly focused on the mid-1990s, and the vehicle designs of this period have been in use for more than 30 years. As time goes by, most of these vehicles have shown poor conditions, and key elements such as their manufacturing materials, performance parameters, and load-bearing structures no longer meet the requirements of current railway technical policies. This not only limits the operating efficiency and safety of the vehicles but also hinders the further development of railway transportation technology.

[0003] In recent years, with the continuous development and upgrading of railway transportation technology, especially the rapid progress of railway container technology, significant changes have occurred in current mainstream containerized equipment. Taking the 20-foot 35-ton open-top container as an example, its container height reaches 2896 mm. Such large containers require higher single-vehicle load-bearing capacity and larger vehicle external contour dimensions to adapt during transportation. However, the existing special vehicles for transporting containers on metre-gauge railways were not fully designed considering this change, resulting in their inability to meet the transportation requirements of new containers in terms of both single-vehicle load-bearing capacity and maximum vehicle external contour. Especially when loading bulk cargo, the limitations of the existing special vehicles for transporting containers on metre-gauge railways are even more prominent. Due to the limitation of vehicle load-bearing capacity, too much cargo cannot be loaded, leading to low transportation efficiency; at the same time, due to the limitation of vehicle external contour dimensions, the railway clearance space cannot be fully utilized, further restricting the improvement of transportation capacity. These problems not only limit the wide application of new containers on metre-gauge railways, affecting the transportation efficiency of metre-gauge railways, but also restrict the supporting role of railway transportation in the economic development of specific regions.

[0004] To overcome this technical bottleneck, it is urgent to improve the existing special vehicles for transporting containers to meet the current and future railway transportation requirements. Against this background, the present invention proposes a new special vehicle for transporting containers, aiming to improve the loading efficiency and transportation capacity by optimizing the vehicle structure.
