Description

A road-rail dual-purpose van-type rollover dump truck

technical field

The invention relates to transportation equipment, in particular to a road-rail dual-purpose van-type rollover self-unloading truck.

Background technique

In recent years, in response to the increasingly serious global problem of climate change, my country has vigorously promoted the concept of green and sustainable development, and put forward unprecedented strict requirements for energy conservation and environmental protection. Under the conditions of high standards and strict control, the logistics and transportation industry has a higher demand for equipment. Coupled with the leap-forward development of infrastructure construction in my country in recent years, the demand for sand and gravel aggregates is increasing year by year. The decline in transportation capacity caused by strict environmental protection requirements has brought about an increasingly serious contradiction between supply and demand. As a result, the demand for road-rail intermodal door-to-door transportation has reached an unprecedented height.

Road-rail combined transportation can maximize the advantages of short-distance highway, medium- and long-distance transportation, and highlight its advantages in the fierce market competition, so as to gain more market share, and strive for the lowest transportation cost and the highest transportation efficiency.

The existing bulk material transportation takes sand and gravel aggregates as an example. The main purpose is to transport the mined sand and gravel to the railway freight yard through road engineering vehicles for storage, and then load them into railway freight cars by construction machinery for medium and long-distance transportation. , and then unloaded to the destination railway freight yard, and then loaded on the road engineering vehicle by the loader, and delivered to the target customer site. The whole process needs to go through three loading and unloading processes. The loading and unloading process of bulk material is recognized as the most serious process of fugitive dust. In the whole logistics process, the main auxiliary costs are: the cost of two railway freight yards, the cost of loading and unloading labor and equipment, the cost of dust control in the station and the loading and unloading process, etc. The total cost increase caused by the auxiliary cost is very large.

Therefore, it is necessary to design a road-rail dual-purpose door-to-door transportation equipment with rollover and self-unloading function, which does not need to occupy the railway freight yard during the whole transportation process, and can deliver the goods to the target customer's place with only one loading.

SUMMARY OF THE INVENTION
