Problems solved by technology

[0003] Because the electric locomotive has been put into production for a long time, the commutator of the DC traction auxiliary motor is worn out, and the insulation layer of the internal winding is aging, resulting in faults such as inter-turn short circuit. The DC traction auxiliary motor has no maintenance value, and there is currently no supply channel and no production. manufacturers, seriously affecting the normal operation and maintenance of ZG80-1500 electric locomotives, and greatly restricting the completion of production and transportation tasks

Abstract

The invention discloses a ventilating device of an electric locomotive for mining. The ventilating device is characterized by comprising a direct current traction motor, a coupler, a first bearing component, a second bearing component and a fan, wherein the fan is fixed on the first bearing component and the second bearing component, and an impeller shaft of the fan is connected with a rotating shaft of the direct current traction motor through the coupler. The ventilating device can replace a ventilating system of an original industrial and mineral electric locomotive, the service life of the electric locomotive is prolonged, the overall technical state of the industrial and mineral electric locomotive is improved, and the overhaul cost can be further reduced.

Description

Technical field [0001] The invention relates to a ventilation system, in particular to a ventilation device for a mine electric locomotive. Background technique [0002] The ZG80-1500 electric locomotive is a traction power car powered by an external catenary and driven by a DC traction motor. It is the main equipment for mine railway transportation. This type of locomotive low-voltage generator, DC traction auxiliary motor and ventilator work coaxially. The ZQD-11 DC traction auxiliary motor rotates. On the one hand, it drives the coaxial impeller to generate wind and sends air to the main motor and the main resistance chamber through the air duct, removes dust, and dissipates; on the other hand, it drives the low-voltage generator to excite and generate power and supply power The low-voltage power supply of the locomotive is used, and the battery pack of the locomotive is charged. [0003] Since the electric locomotive has been put into production for a long time, the commutato...
