Description

Technical Field

[0001] This invention relates to the field of transportation machinery technology, specifically to a monorail electric transportation machine for mountain transportation. Background Technology

[0002] Tibet boasts abundant photovoltaic resources, but its unique conditions of high altitude, low oxygen, and fragile ecology pose severe challenges to engineering construction. Traditional mountain transport equipment relies on internal combustion engines, which expose significant shortcomings in high-altitude environments: insufficient power: thin oxygen leads to incomplete combustion, resulting in a significant decrease in driving force; environmental pollution: incomplete combustion of fuel emits harmful substances, disrupting the ecological balance of the plateau; structural redundancy: the separate design of the tractor unit and the cargo box results in a large size, cumbersome steering, and difficulty in adapting to narrow mountain paths; safety hazards: the lack of a reliable braking mechanism when descending steep slopes easily leads to "runaway" accidents.

[0003] While existing electric transport equipment avoids pollution problems, it still suffers from shortcomings such as long drive chains, weight imbalance, and lack of slope self-locking function, failing to meet the green and efficient transport needs of complex plateau terrain. Therefore, there is an urgent need for a mountain transport equipment that integrates a compact structure, intelligent safety control, and zero-emission drive. Summary of the Invention

[0004] To address the problems of long transmission chains, weight imbalance, and lack of slope self-locking function in existing electric transportation equipment, this invention provides a monorail electric transportation machine for mountain transportation. It integrates the drive structure with the transport vehicle to optimize weight distribution, directly connects the worm gear reducer with the drive wheel assembly to shorten the transmission chain, and utilizes its reverse self-locking characteristic to ensure safety on steep slopes.
