Abstract
The invention discloses a fixing plate hoisting system for a motor train unit cooling system, which includes two cantilevers vertically fixed on the side wall of a traction transformer of the motor train unit, wherein an outer shell used for fixing a draught fan and a cooling system is fixed at the other end of each cantilever; draught fan embedding grooves for the draught fans and cooling system embedding grooves for the cooling systems are formed in the two opposite side surfaces of the outer shells respectively. Through the adoption of the technical scheme, the split design of the two outer shells eliminates the beam hoisting structure, and besides, the draught fans and the cooling systems are assembled in an embedding manner, and are assembled inside the outer shells, so that each outer shell bears lighter weight, further, weight can be born completely as the cantilevers are directly and vertically welded to the side wall of the traction transformer of the motor train unit.

Plane, the plane is often thin plate, in order to improve rigidity, need to improve used by sheet metal thickness or higher using elastic modelling quantity
Material, and both approaches will all cause the increase of product weight.
The content of the invention
The present invention is directed to above-mentioned technical problem, proposes that a kind of small size, the EMUs cooling system fixed plate of low weight hang
Dress system.
For reaching object above, it is achieved through the following technical solutions：
EMUs cooling system fixed plate lifts system, including：It is perpendicularly fixed at the outstanding of motor train unit traction transformer side wall
Arm beam, and cantilever beam quantity is 2；Shell body quantity for fixing blower fan and cooling system is 2；Each cantilever beam is another
End is respectively fixed with a shell body；
Shell body two relative side is provided with and is respectively used to fix the embedded groove of the blower fan of blower fan and cooling system and cooling
System embedment groove；
The embedded groove inner wall of blower fan is provided with fixed plate；Fixed plate one end is by bolts assemblies in the embedded groove inner wall of blower fan
End, and fixed plate assembling mode is to be radially extended by the embedded groove center axis of export-oriented blower fan；
Fixed plate is machined with the screwed hole fixed for assembling；
The embedded groove inner wall of cooling system is provided with cooling system shell and fixes batten；
Cooling system shell is fixed batten and cooling system and is embedded in groove inner wall and fitted assembling by bolt assembly；
Cooling system shell is fixed batten and is machined with the screwed hole for installing fixation for cooling system shell；
Using the present invention of above-mentioned technical proposal, by two shell body split-type designs, transverse beam lifting structure is eliminated,
And blower fan and cooling system are assembled and shell body mounted inside for embedded, and so each shell body load capacity is lighter, enters
And pass through the direct vertical welding of cantilever beam and fix (or bolts assemblies are fixed) to be held in motor train unit traction transformer side wall completely
Loading capacity, and blower fan assembling, fixed plate is radially assemblied in the embedded groove inner wall of blower fan first, and (fixed plate quantity is according to actual need
Depending on seeking load capacity), then coordinate blower fan is anchored in fixed plate with the screwed hole of fixed plate by bolt and realize fixing；
Cooling system is assembled, and cooling system shell is fixed batten and is assemblied in the embedded groove inner wall of cooling system by bolt laminating first,
Then the screwed hole for fixing batten by bolt and shell coordinates assembling, and the shell of cooling system is fastened；
For being oppositely arranged, the relative assembling of such blower fan greatlys save entirety to the embedded groove of the blower fan of two shell bodies
Installing space.
It is to sum up of the invention,
1) eliminate transverse beam lifting structure, and all-in-one-piece cooling system weight be larger, thus the patent employ will be cold
But system is divided into the two symmetrical junior units in left and right, and thus two junior units can independently be lifted on cooled down object and (generally lead
Draw transformator or traction convertor) cantilever beam on.
2) product weight is controlled, the program adopts aluminium alloy as the material of main part of framework.In lifting link position, the party
Case is avoided is fixed using welding threaded block, be it also avoid directly fixing using nut, but is employed fixed plate and cooling system
System shell is fixed batten and is installed, and in this scheme, fixed plate and cooling system shell are fixed batten and both provided the function of installing, together
When contacted with mounting surface due to entirety, improve the rigidity of mounting surface.
The beneficial effect that technical solution of the present invention is brought
Technical solution of the present invention has following several respects for the volume and weight for reducing product (for above example)：
1) as crossbeam is typically located at the both sides of car body in the Hoisting Position of underbody, quantity is 2, that is, the crossbeam length cancelled
Substantially long at 2.5 meters, if using 8# channel-section steels, rough estimate, the weight for being mitigated are 40kg, if considering in order to reinforcement structure is steady
It is qualitative and design longeron, then mitigate weight it is more；
2) cancel crossbeam after, shared by crossbeam, volume is then fully phased out, the lifting cantilever beam on tractive transformer to it is related
Cooling line be interweaved, and prevent take up more spaces；
3) as fixed plate and cooling system shell are fixed batten to increase rigidity so that chassis body material can make
In the case of aluminium alloy, sheet metal thickness is not significantly increased.Rough estimate, uses carbon steel using aluminium alloy as material is comparable
Mitigate weight 15kg as material；
4) due to using fixed plate installing blower fan, so the assembling face on framework uses 4mm aluminium alloy plates,
Alleviate product weight；Simultaneously because threaded block need not be welded so that the mounting structure of blower fan is compacter, and (fixed plate is only
8mm is thick, if being connected using threaded block, threaded block height is in 15～20mm).
