Abstract

The invention relates to a storage-battery-type fast-frequency-conversion electric locomotive which belongs to a storage-battery-type fast-frequency-conversion electric locomotive. The electric locomotive is mainly used for solving technical problems such as large energy consumption, low speed, insufficient running capacity, low working efficiency, and the like of existing storage-battery-type fast-frequency-conversion electric locomotives. The invention adopts a technical scheme that: the electric locomotive comprises a cab (1), a storage battery box (2), and a frame (22). The frame (22) adopts a streamlined structure. The cab (1) and a vehicle rear control room (23) are respectively arranged on front and back ends of the frame (22). The storage battery box (2) is arranged on the upper part of the frame (22) between the cab (1) and the vehicle rear control room (23) An air braking device is arranged below the storage battery box (2) and on the back side of the cab (1). The electric locomotive is mainly used in coal mine tunnel transportation.

Description

technical field [0001] The invention relates to a battery electric locomotive, in particular to a battery type fast variable frequency electric locomotive. Background technique [0002] At present, most domestic mining explosion-proof special battery electric locomotives use resistance, chopper speed regulation, and DC motors. There is no energy feedback during operation, and the energy consumption is relatively large. The design speed is generally only 8.7km / h, and the actual operating speed is 6km / h. The speed is slow, and there is generally insufficient transportation capacity, which seriously affects the production capacity of coal mines, and the work efficiency of a single person is not high. [0003] For example, Liu Huaidong of No. 47 Mengshan Road, Xiangshan District, Huaibei City, Anhui Province applied for a patent on March 02, 2010 and published on October 20, 2010. The application number is CN201029044173 "Frequency Conversion Explosion-proof Special Battery Elec...
