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.

Summary of the invention
The present invention is directed to above-mentioned technical matters, propose the motor train unit cooling system adapter plate lifting system of a kind of small size, low weight.
For reaching above object, be achieved through the following technical solutions:
Motor train unit cooling system adapter plate lifting system, comprising: be vertically fixed on the cantilever beam of motor train unit traction transformer sidewall, and cantilever beam quantity is 2;
The cantilever beam other end is fixed with for the fixing body skin of blower fan and cooling system;
Body skin two relative side is provided with blower fan embedding groove and the cooling system embedding groove that is respectively used to blower fan and cooling system;
Blower fan embeds groove inwall and is provided with adapter plate; Adapter plate one end embeds groove inwall end by bolts assemblies and blower fan, and the adapter plate assembling mode export-oriented blower fan of serving as reasons embeds groove central axis and radially extends;
Adapter plate is processed with for the fixing tapped bore of assembling;
Cooling system embeds groove inwall and is provided with fixedly batten of cooling system shell;
Cooling system shell fixedly batten is to embed groove inwall by the bolt assembly assembling of fitting with cooling system;
Cooling system shell fixedly batten is processed with for cooling system shell fixing tapped bore is installed;
Adopt the present invention of technique scheme, by two body skin split-type design, cancelled transverse beam lifting structure, and blower fan and cooling system are for embedding assembling and body skin mounted inside, each body skin load capacity is lighter like this, and then by the direct vertical welding of cantilever beam, fix (or bolts assemblies is fixed) completely can load capacity in motor train unit traction transformer sidewall, blower fan assembling again, first adapter plate radially loading is assigned in to blower fan and embeds groove inwall (adapter plate quantity according to the actual requirements load capacity and determine), then by bolt, coordinate with the tapped bore of adapter plate blower fan is anchored on adapter plate and realizes and fixing, cooling system assembling, first cooling system shell fixedly batten by bolt, fit and be assemblied in cooling system embedding groove inwall, then by bolt and shell fixedly the tapped bore of batten coordinate assembling, the shell of cooling system is fastening,
The blower fan of two body skiies embeds groove for being oppositely arranged, and blower fan is assembling relatively like this, has greatly saved integral installation space.
To sum up the present invention,
1) cancelled transverse beam lifting structure, and all-in-one-piece cooling system weight is larger, so this patent has adopted, cooling system is divided into two the symmetrical junior units in left and right, thus two junior units can independently be lifted on the cantilever beam of cooling object (being generally traction transformer or traction convertor).
2) control product weight, this scheme adopts aluminum alloy as the material of main part of framework.At lifting connection location, this scheme has avoided using welding threaded block to fix, also avoided direct use nut to fix, but adopted the fixedly batten installation of adapter plate and cooling system shell, in this scheme adapter plate and cooling system shell fixedly batten the function of installing was both provided, due to whole, contact with attachment face simultaneously, improved the rigidity of attachment face.
The beneficial effect that technical solution of the present invention is brought
Technical solution of the present invention has following several respects (for above example) for the volume and weight that reduces product:
1) due to crossbeam generally the Hoisting Position at the bottom of car be positioned at the both sides of car body, quantity is 2, the crossbeam length of cancelling is roughly long at 2.5 meters, if use 8# channel-section steel, guestimate, the weight alleviating is 40kg, the longeron designing in order to strengthen structural stability if consider, and expendable weight is more;
2) cancel after crossbeam, the shared volume of crossbeam has fully phased out, and the lifting cantilever beam on traction transformer is interweaved to relevant cooling line, does not occupy more space;
3) due to adapter plate and cooling system shell fixedly batten increase rigidity, make the chassis body material can be in the situation that using aluminum alloy, sheet metal thickness significantly increases.Guestimate, use aluminum alloy as the comparable use carbon steel of material as material expendable weight 15kg;
4), owing to adapter plate, blower fan being installed, so the assembling face on framework is used 4mm aluminium alloy plate, alleviated product weight; Owing to not needing to weld threaded block, make the mounting structure of blower fan compacter (adapter plate is only thick for 8mm, if use threaded block to connect, threaded block height is at 15～20mm) simultaneously.
