Abstract
An urban subway vehicle transformer mounting structure is characterized in that a lower plane of a vehicle body underframe side beam is provided with a slide groove, the side of the vehicle body underframe side beam is provided with an L-shaped flange by riveting, a transformer is provided with four dampers, each damper is provided with double rows of lifting holes, and double row lifting of the transformer is achieved through the slide groove added to the lower plane of the vehicle body underframe side beam and the L-shaped flange arranged at the side of the vehicle body underframe side beam. By providing the slide groove in the lower plane of the vehicle body underframe side beam, providing the L-shaped flange at the side of the vehicle body underframe side beam by riveting, and using the double rows of lifting holes of the four dampers of the transformer, double row lifting of the transformer is achieved, equipment lifting strength and damper mounting contact area are guaranteed, and lifting the transformer is achieved under vehicle body and under-vehicle equipment limits of traditional subway vehicles.
Description
Technical field
The invention belongs to rail vehicle power supply technique field, especially relate to a kind of installation knot of rail vehicle transformator
Structure.
Background technology
Railcar is all to operate in urban district now, and the supply voltage of employing is DC1500V or DC750V, adopts
Directly-alternating current drive system；In order to realize intercity and round in the urban district demand run of rail vehicle, vehicle needs exist
All can run under the supply voltage of AC25KV and DC1500V, AC-DC-AC stream and straight-alternating current drive system need to be adopted simultaneously,
It is thus desirable to transformator is installed additional on vehicle.Added the big weight of volume of transformer due to being fitted without transformator before greatly,
Therefore it is not suitable for the transformator mounting structure of Car Body Structure in Subway.
At present, the transformator of CRH3 EMUs is to be directly installed on vehicle body bottom frame edge-beam section steel by vibroshock.Due to
Under EMUs sling cart, the vehicle body bottom frame edge-beam section steel width of equipment is big, disclosure satisfy that the bolt specification of transformator lifting（M24）.
And vehicle body bottom frame edge-beam section steel is affected to be applied to subway with factors such as bogie interface relationships by body construction and car body
In, therefore cannot borrow the mounting structure of moving vehicle set transformer.
Content of the invention
It is an object of the invention to provide a kind of transformator mounting structure adapting to the intercity operation demand of rail vehicle, make vehicle
All can run under the power supply system of AC25KV and DC1500V.
For achieving the above object, the present invention provide a kind of city railway vehicle transformator mounting structure it is characterised in that：
It is provided with chute, vehicle body bottom frame side bar side staking L-type flange in vehicle body bottom frame side bar lower plane, transformator carries four and subtracts
Shake device, and each vibroshock carries double hole for hoist, using the chute of vehicle body bottom frame side bar lower plane increase and the L-type flange of side
Realize the double lifting to transformator.
In order to ensure uniform force after lifting, vehicle body bottom frame side bar lower plane is concordant with the lower plane of L-type flange.In order to protect
Card intensity, L-type flange adopts weathering steel bending.
The present invention is by being provided with chute, vehicle body bottom frame side bar side staking L-type flange, profit in vehicle body bottom frame side bar lower plane
The double hole for hoist of four vibroshocks being carried with transformator, realize double to transformator lifting it is ensured that equipment hoisting intensity and
The installation contact area of vibroshock, under conditions of facilities clearance under the car body and car of traditional railcar, realizes to transformator
Lifting.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is the A direction view of Fig. 2；
Fig. 4 be Fig. 2 I to enlarged drawing；
Fig. 5 is scheme of installation of the present invention.
Specific embodiment
Reference picture 1- Fig. 5, transformator 1 is conducted oneself with dignity 3.9 tons, in order to ensure to lift intensity, in the form of the double lifting of vibroshock.Become
Depressor carries four vibroshocks 3, and each vibroshock carries double hole for hoist, and often row's lifting hole number is four.Double in order to realize
Row's lifting form, increases chute in vehicle body bottom frame side bar 2 lower plane, and is needing riveting and vehicle body bottom frame side at hanging device
The concordant L-type flange 4 of beam lower plane 8, so using vehicle body bottom frame side bar lower plane increase chute and L-type flange carry out double
Lifting.In order to ensure that after lifting, uniform force is it is desirable to vehicle body bottom frame side bar lower plane is concordant with the lower plane of L-type flange.In order to
Proof strength, the employing weathering steel bending of L-type flange, due to, therefore L-type flange inconsistent with the aluminium material of vehicle body bottom frame side bar
Riveting form is adopted and vehicle body bottom frame side bar between.
First the bolt 6 being installed with slide block is nuzzled in advance in the chute of vehicle body bottom frame side bar lower plane during installation and cunning will be installed with
The bolt of block pass through L-type flange installation in the hole, the slide block at two is all to play anti-rotating function, so by outside car body from
Nut 7 is fastened and is applied the requirement that corresponding Tightening moment value has just reached transformator lifting.The reinforcement of L-type flange removes
Play the booster action of structural strength, also act as the anti-rotation effect assisting slide block, 5 be rivet.
Claims (3)
1. a kind of city railway vehicle transformator mounting structure it is characterised in that：It is provided with chute, car body in vehicle body bottom frame side bar lower plane
Edge beam of underframe side staking L-type flange, transformator carries four vibroshocks, and each vibroshock carries double hole for hoist, using car
The chute that body edge beam of underframe lower plane increases and the L-type flange of side realize the double lifting to transformator.
