Description
Technical field
The present invention relates to a kind of engine hood of passenger train, belong to bus body technical field, more particularly to a kind of double-layer seal
Engine hood of passenger train, it is particularly applicable to the structure of double-layer seal, double glazing steel improve hood corrosion resistance, every
Hot decrease of noise functions and mechanical strength, and be easily installed.
Background technology
At present, engine hood of passenger train is generally using three kinds of forms, i.e. all-glass fibre reinforced plastic formula hood, steel plate type engine
Cover, steel skeleton fiberglass reinforced plastics formula hood.Engine can produce larger heat as a radiating piece, and adding can be by water tank etc.
More component compresses limit air-flow in engine neighboring area, cause engine case temperature to increase, especially for hair
The preposition car of motivation, heat and noise turn into its incoming in-car main path by hood.
At present, most of hoods use steel skeleton fiberglass reinforced plastics formula structure, and concrete operations technique is needed reinforcing bar first
Frp layer, is then attached on skeleton, when mounted, it is necessary to first steel skeleton is positioned, then by frame formation assembly
Frp layer is also positioned.Such structure adds the complexity of operating procedure, in terms of noise reduction and thermal insulation
Have little effect, the riding comfort of influence driver and passenger.Also some hoods use steel plate type structure, this structure
Although manufacture craft is simple, its heat-insulation noise-reduction performance is worst, and corrosion resistance is also poor, and mechanical strength is relatively low, and
In installation process, it is necessary to first be positioned as steel skeleton fiberglass reinforced plastics formula hood, the complexity of mounting process is added
Degree, reduces operating efficiency.
Chinese patent, Authorization Notice No. is CN202358185U, and authorized announcement date is in August, 2012 utility model of 1 day
Patent discloses a kind of engine hood of passenger train, including cover plate, cover body and seal, and cover plate is located at cover body top and one end of cover plate
It is hinged on cover body, the other end of cover plate is buckled on cover body, seal includes sealing joint strip and sponge rubber, sponge rubber is solid
On the in-flanges for being scheduled on cover body upper end, sealing joint strip is fixed on the inwall of lid and contacted with sponge rubber, cover plate and cover body
From-inner-to-outer is composited by frp layer, polyurethane foaming layer and polyvinyl chloride layer.Although the design by by cover plate, cover
The manufacture material selection of the inner panel of body is fiberglass, adds somewhat to mechanical strength and corrosion resistance, but it still has
There is following defect：
First, one layer of sealing is only taken in the design, and sealing effectiveness is weaker, it is difficult to reduce the heat of the parts such as engine generation
And noise enters interior of body, the corrosion resistance and heat-insulation noise-reduction of engine hood of passenger train are reduced；
Secondly, only have cover plate, the inner panel of cover body to use glass-reinforced plastic material in the design, and the outside plate of cover plate, cover body is selected
Polyethylene layer is selected as, mechanical strength on the whole is still relatively low, and corrosion resistance is weaker；
Again, the design then pastes various heat-barrier materials in assembling, it is necessary to first positioned to inner panel thereon, step
It is rapid cumbersome, easily reduce operating efficiency.
The content of the invention

Closely knit rubber and plastic+rigid composite is formed, and is fixed on the interior along along side of pedestal assembly outside plate, and No. two sealing strips are closely knit rubber-plastic sealing glue
Bar, by buckle or（With）Viscose glue is fixed on cover assembly inner panel.Two sealing strips are squeezed between cover assembly, pedestal assembly
Means of press seals.
When hood deploys, two sealing strips belong to Different Plane, when hood is closed, from top view
See, No. two sealing strips are set in the surrounding of a sealing strip, realize double-layer seal, so that two layers of protection is carried out to heat, noise,
The possibility that the heat that engine and miscellaneous part produce enters interior of body by hood can be greatly reduced, make car
The corrosion resistance enhancing of hood, and improve its sound-insulating and heat-insulating anti-acoustic capability.
2nd, inside and outside all-glass fibre reinforced plastic design：
Cover assembly outside plate, cover assembly inner panel, pedestal assembly outside plate, the manufacture material of pedestal assembly inner panel in the present invention
What material was all that fiberglass, i.e. cover assembly, pedestal assembly take is all inside and outside double glazing steel design, this meaning cover assembly,
The shell of pedestal assembly is all-glass fibre reinforced plastic formula, not only substantially increases the mechanical strength, corrosion resistance and heat-insulated drop of hood
Make an uproar function, and can during fabrication, just populated various heat-insulation noise-reduction materials between inside and outside double glazing steel so that in assembling
When, it is not required to position, is not required to paste heat-insulation noise-reduction material, only need to be directly assembled by screw hole, operating efficiency is higher.
3rd, heat-insulation noise-reduction material：
