Mounting device for traction motor flexible air duct

Abstract

The invention provides a mounting device for a traction motor flexible air duct. The mounting device for the traction motor flexible air duct comprises a sealed frame for tightening the flexible air duct on a traction motor. The sealed frame is an annular frame with an opening at one end; and the open end of the annular frame clamps the flexible air duct and the traction motor through tightening pieces. According to the mounting device for the traction motor flexible air duct, a problem that it is difficult for a plurality of bolts to match with hole positions because the plurality of bolts are adopted between the traction motor flexible air duct and the traction motor in the prior art is avoided. When the flexible air duct needs to be detached in the actual operation and maintenance of a locomotive, the sealed frame can be detached without detaching the plurality of bolts and only by detaching one tightening piece do not need to be detached; therefore, the production efficiency is increased. A connecting opening between the traction motor flexible air duct and the traction motor is positioned within a narrow space under the locomotive and the operation space under the locomotive is very limited, the mounting and detaching of the traction motor flexible air duct and the traction motor are simplified by using a mode of using the tightening piece to detach the sealed frame; therefore, the mounting device for the traction motor flexible air duct is time saving and labor saving and the actual working efficiency is further increased.

Description

technical field [0001] The invention belongs to the technical field of rail transit electric locomotives, and in particular relates to an installation device for a soft air duct of a traction motor. Background technique [0002] During the operation of the locomotive, the traction motor installed on the bogie under the locomotive converts electrical energy into mechanical energy, which provides power for the locomotive to move forward in the form of high-speed operation. Since the traction motor will generate a large amount of heat energy when it runs at high speed, in order to avoid the temperature of the traction motor from being too high during operation, the traction motor needs to be cooled by forced air to cool the traction motor in addition to the surface when the locomotive is running. Locomotives usually use air drawn from the traction fan in the locomotive machinery room to feed the traction motor under the car for forced ventilation and cooling. However, during t...

AI Technical Summary

Problems solved by technology

However, since there are usually many components installed under the vehicle, the space is narrow, and the distance between the air inlet of the traction motor and the chassis is relatively close, when it is necessary to install the soft air duct of the traction motor (the other end of which has been installed When the air inlet of the traction motor is separated or vice versa, due to the very limited operating space for tightening and removing bolts, so many bolts need to be tightened or removed, which is undoubtedly a time-consuming and laborious process

And there is always relative movement between the locomotive body and the bogie during the operation of the locomotive, and the soft air duct of the traction motor is in a state of distortion and deformation for a long time, and its replacement frequency will be higher than other parts

For this kind of locomotive's vulnerable and consumable parts, in addition to considering the use characteristics of the parts themselves, their ease of installation and maintainability must also be considered at the beginning of the design, otherwise a lot of manpower and material resources will be wasted in actual use and maintenance
