Low-emission narrow-track diesel locomotive used for tunnels

Abstract

The invention relates to a low-emission narrow-track diesel locomotive used for tunnels. The diesel locomotive comprises a cab, a fuel system, an air system, a hydraulic transmission box, a cardan shaft, an axle gear box and wheel set, and a diesel engine. The cab is provided with a control console and a seat, and a warning lamp and a horn are disposed in front of the cab. The diesel engine is in connection with the axle gear box and wheel set. The axle gear box and wheel set is connected to the cardan shaft, which is in connection with a driving wheel of the locomotive. The diesel locomotive also includes a noble metal purifier arranged at an exhaust pipe. The overall locomotive frame adopts a modular design, has the characteristics of reasonable structure, safety and reliability, convenient mounting and dismounting. The hydraulic transmission box has more stable power transmission, and is safer to apply. The noble metal purifier effectively reduces the carbon monoxide, hydrocarbons, soot particles and the like in emitted pollutants. The filtered exhaust gas meets the basic requirements for low emission and environmental protection of the locomotive, and ensures air health in tunnels.

Description

technical field [0001] The invention relates to a low-emission narrow-gauge diesel locomotive for tunnels. Background technique [0002] In recent years, domestic tunnel construction has advanced by leaps and bounds and entered a new period of development. From the construction of long and deep tunnels for high-speed railways to the excavation of subway tunnels, from the water conservancy culverts of the South-to-North Water Diversion Project to the water diversion culvert tunnels of hydropower projects, the tunnels have become more and more There are more and more tunnels, and they are getting longer, and so are the developments in tunnel construction for hydropower systems.

AI Technical Summary

Problems solved by technology

[0003] Most of the current construction of long tunnels uses diesel locomotives to pull transport vehicles to unload slag, tow and transport engineering materials, and transport personnel entering and leaving the tunnel. Especially in tunnels with a length of more than 10km, diesel locomotives have become the first choice and necessary power for tunnel engineering. Equipment, because battery-powered locomotives require a certain charging time and the size of the power storage is limited, they cannot meet the requirements of long-distance tunnel operations. Therefore, it has become a development trend to replace battery-powered locomotives with internal combustion-powered locomotives for tunnel excavation operations

[0004] In the operation of long tunnels, the ventilation conditions are severely restricted, and the pollutants emitted by diesel locomotives seriously affect the physical and mental health of the staff. In the current era of vigorously advocating an environmentally friendly society, environmental protection and humanistic protection are particularly important. Therefore, the developed New low-emission and environmentally friendly diesel locomotives are very necessary and the general trend. However, there are no products that can solve these problems yet.
