Air channel device of locomotive traction motors

Abstract

The invention discloses an air channel device of locomotive traction motors. An upper flange is welded to a bottom frame of a locomotive body; one end of an air channel hose is fixed to the upper flange through a throat hoop, and the other end of the air channel hose is fixed to one side of a lower flange assembled on a base through the throat hoop; a stop block is fixed to an air inlet of each traction motor; and a flange bottom plate assembled on the base is inserted in the stop block. The air channel device disclosed by the invention has the beneficial effects that the quality and the operation safety of a locomotive can be guaranteed; besides, the problems that the motors are damaged by high temperature caused by air leakage of an air channel, the motors need to be changed, and transporting costs for delivering fittings are high are solved; the improved air channel device can be simple in the mounting and disassembling operation, quick to mount or disassemble, and convenient and swift; and labor costs and transporting costs are greatly saved.

Description

technical field [0001] The invention relates to an air duct device for a traction motor of a locomotive. Background technique [0002] The harmonious diesel shunting locomotive produced by our company is a six-axle transmission locomotive with a speed of 100Km / h. The locomotive has six traction motors, and the traction fan in the mechanical room ventilates and cools the traction motors through the traction motor air duct device. The wind of the traction fan comes out through the air outlet of the underframe of the car body, passes through the air duct device of the traction motor, and reaches the air inlet of the traction motor. The hose assembly is connected with the upper flange and the lower flange of the base assembly through throat hoops. The connecting device must be tight and reliable, otherwise it will cause air leakage, and if the motor temperature is too high, it will cause the motor to burn and stop, which will cause very large losses to the locomotive. In addit...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to propose a locomotive traction motor air duct device for the problems that the bolts close to the frame beam side often fall off during the actual operation of the locomotive in the prior art, resulting in air leakage in the air duct and overheating of the traction motor.
