Hanging device for traction auxiliary power supply all-in-one converter of motor train unit

Abstract

The invention relates to a hanging device of an object, in particular to a hanging device for a traction auxiliary power supply all-in-one converter of a motor train unit, solving the problem that no hanging device is suitable for the traction auxiliary power supply all-in-one converter of the motor train unit. The hanging device comprises a left hanging bracket, a middle hanging bracket and a right hanging bracket which are respectively consistent to the left part, the middle and the right part of the upper end surface of a box body of the traction auxiliary power supply all-in-one converterin shape, wherein the opposite side walls of the left hanging bracket and the middle hanging bracket and the middle hanging bracket and the right hanging bracket are provided with opposite assemblingholes; the upper end surfaces and the lower end surfaces of the hanging brackets are provided with fixed through holes; and hanging installation seats are fixed on the side walls of the hanging brackets. The hanging device ensures the hanging strength of the traction auxiliary power supply all-in-one converter equipment of the high-speed motor train unit, meets the technical requirements for the light weight of the traction auxiliary power supply all-in-one converter equipment of the high-speed motor train unit and solves the problems of the large-area hanging and the planeness of the traction auxiliary power supply all-in-one converter equipment.

Description

technical field

[0001] The invention relates to a hanging device for an object, in particular to a hanging device for an integrated converter for traction auxiliary power supply of a multiple train set. Background technique

[0002] The traction converters and auxiliary converters on the existing high-speed EMUs are independent in structure and self-contained, and are hung under the train by means of a hanging device with an integral welded structure with the converter box. With the continuous increase of the speed of high-speed EMUs, the required train power is also increasing, and the volume and weight of the traction converters and auxiliary converters that provide power for the trains are also correspondingly increased. The hanging device with integrated welded structure of the box can no longer carry the large-volume and heavy-weight converter, and the traction and auxiliary converters are designed separately, which has many connections and requires two sets of cooling ...
