Description

Technical Field

[0001] The invention belongs to the technical field of transport vehicle design and manufacturing, and relates to a vehicle-mounted open-top container transport bearing and lifting structure with a buffer door stopper. Background Art

[0002] In recent years, the country has gradually increased the promotion and application of 35-ton open top containers for long-distance railway transportation of bulk raw materials such as coal, sand and gravel aggregates, and combined them with short-distance road transportation, effectively complementing each other's advantages and promoting cost reduction and efficiency improvement in the industry's transportation.

[0003] During the entire process of 35-ton open-top container transportation, bulk material loading and container lifting have been mechanized. However, during the bulk material unloading stage, because conventional container transport skeleton semi-trailers do not have the ability to unload themselves, they need to use additional equipment such as large vehicle tipping platforms, and even need to add container lifting and transfer operations, such as lifting the container to a special container tipping mechanism, in order to achieve bulk material tipping. This greatly affects the overall transportation efficiency of the container.

[0004] At the same time, when operators open the door of a container loaded with bulk materials with good fluidity, the bulk materials are prone to impact the door and endanger the safety of the operators.

[0005] When a 35-ton open-top railway container is fully loaded, its total mass reaches 35 tons, which greatly affects the load distribution of the transport vehicle. As a result, when a conventional skeleton vehicle transports a fully loaded 35-ton open-top railway container, the front load distribution is small, which makes it easy to slip when climbing a slope, affecting driving safety.
