Abstract

The invention relates to the technical field of diesel locomotives, in particular to a narrow-gauge alternating-current transmission diesel locomotive. The narrow-gauge alternating-current transmission diesel locomotive comprises an upper locomotive body, a lower locomotive body, a cab, an auxiliary chamber, an electric chamber, a power house, a cooling chamber, a load bearing type fuel tank, a bogie and a locomotive frame. The upper locomotive body is composed of the cab, the auxiliary chamber, the electric chamber, the power house and the cooling chamber. The lower locomotive body is formed by the load bearing type fuel tank and the bogie. The cab is arranged on one side of the auxiliary chamber, the electric chamber is arranged on the other side of the auxiliary chamber, and the power house is arranged between the electric chamber and the cooling chamber. Partition walls are respectively arranged among cavities except the auxiliary chamber and the electric chamber. The bogie is arranged on two sides of the load bearing type fuel tank. The locomotive frame is arranged between the upper locomotive body and the lower locomotive body. The narrow-gauge alternating-current transmission diesel locomotive is compact and reasonable in structure, convenient and fast to assemble, reliable in connection, applicable to a narrow-gauge line, capable of adapting to various severe climatic environments, simultaneously small in daily maintenance and easy to use and popularize.

Description

technical field [0001] The invention relates to the technical field of a diesel locomotive, in particular to a narrow-gauge AC drive diesel locomotive. Background technique [0002] The Australian railway transportation market is a high-end market for diesel locomotives in the world. It is dominated by heavy-duty freight, mainly transporting coal, iron ore and other minerals from inland mining areas to ports. Some of the lines in Queensland are narrow gauge lines (gauge 1067mm). However, there are very few domestic diesel locomotive manufacturers, and due to the high local labor costs, the complete vehicle price of local diesel locomotives is very high. In order to improve its own competitiveness and reduce costs, the Australian Railway Transport Company hopes to purchase complete sets of cost-effective railway rolling stock equipment from China. In order to meet this demand, a narrow-gauge AC drive diesel locomotive is required to meet the traction demand of freight train...
