Abstract

The utility model provides a double-ladle folding hood windshield for passenger corridor of train, consisting an end frame(1), a folding hood(2) and a connection frame(3) which are connected with each other, wherein the folding hood(2) comprises an inner folding hood(4), an outer folding hood(5), an end part connector(6) and a middle part connector(7); the end frame(1) is provided with a rubber sealing strip(8); the connection frame(3) is provided with a rubber sealing strip(10) and a connecting bolt(9). The windshield has good stretching, sealing and heat insulation effects and resolves the problems that in winter, the inner side of the windshield is iced, the windshield cloth is ruptured and the windshield is seriously damaged; the windshield is good in sound insulation and can meet the requirement of the high speed train on the sound insulation index.

Description

Double-wrapped Covering Windscreen

Technical field

The utility model relates to a kind of passenger train passenger route windscreen, particularly a kind of Double-wrapped Covering Windscreen.

Background technology

Existing passenger train passenger route windscreen has two kinds: a kind of is that ground main line vehicle uses, and its windscreen vestibule diaphragm cloth ring is a single layer structure, and effect of heat insulation is poor, and freezed in winter is serious; Another kind is that railcar uses, and its windscreen vestibule diaphragm cloth ring is a double-decker, and is heat insulation, soundproof effect is better, but still is difficult to satisfy operating needs.With the raising of landing ground main line train speed, the inside and outside temperature difference of windscreen in winter is often greater than 30 ℃, and the inboard phenomenon of freezing of windscreen is more and more serious, causes windscreen cloth to break, and windscreen damages; With the raising of landing ground main line train speed, passenger train passenger route windscreen place has become serious vibration, noise radiation source, is difficult to satisfy the requirement of high speed train to the weighted sound reduction index.

Summary of the invention

The purpose of this utility model provides a kind of have well heat insulation, defening effect on the train of running at high speed, significantly alleviate the icing phenomenon of wind shelves vestibule diaphragm internal layer, prevents the novel windscreen that windscreen cloth breaks.

The utility model is connected and composed by end frame, folding paulin, connection box.The folding paulin comprises the invagination paulin, rolls over paulin, end connector, middle part adaptor union outward; Each " ∪ " type ring coupling end at invagination paulin and outer folding paulin middle part connects into integral body by each middle part adaptor union correspondence.When two car ends company extension need not decompose, these single-piece two ends linked together by end connector and two end frames respectively; When two car ends even extension need decompose, these single-piece two ends linked together with end frame and connection box respectively by end connector.The invagination paulin, roll over paulin outward and form by a plurality of " ∪ " type ring respectively, two straight ends of " ∪ " type ring respectively with two straight end and downlink connection of adjacent " ∪ " type ring." ∪ " type ring of invagination paulin and outer folding paulin is separately to being connected into closed-loop.The end frame is provided with end frame sealing band.The end frame is shock resistant complex steel sheet structure or non-shock-absorbing type equipment structure, and the shock resistant complex steel sheet structure is made up of " metal/high-molecular combined material/metal " three layers.When two car ends even extension need decompose, also be provided with the binding latch on the connection box.

After passenger train was installed the utility model, the effect of heat insulation of wind shelves significantly improved, and the inboard phenomenon of freezing of windscreen significantly alleviates, and hanged down at the extremely frigid zones winter temperature and reached-40 ℃, and windscreen is got rid of substantially because of the icing situation about damaging in inboard; The sound insulation property of this windscreen is fine, can satisfy the high requirement of high speed train to the weighted sound reduction index.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described:

With reference to the accompanying drawings 1,2, the utility model embodiment is connected and composed by end frame 1, folding paulin 2, connection box 3.Folding paulin 2 ring iron clad road passenger vehicle passenger routes, left and right view symmetry.

With reference to the accompanying drawings 3, the utility model embodiment connects to hang to need to decompose by two car ends and makes, and folding paulin 2 comprises invagination paulin 4, rolls over paulin 5, end connector 6, middle part adaptor union 7 outward; Each " ∪ " type ring coupling end at invagination paulin 4 and outer folding paulin 5 middle parts connects into integral body by each middle part adaptor union 7 correspondence, and these single-piece two ends link together by end connector 6 and end frame 1 and connection box 3 respectively.Invagination paulin 4, roll over paulin 5 outward and form by a plurality of " ∪ " type ring respectively, two straight ends of " ∪ " type ring respectively with two straight end and downlink connection of adjacent " ∪ " type ring." ∪ " type ring of invagination paulin 4 and outer folding paulin 5 is separately to being connected into closed-loop.End frame 1 is non-shock-absorbing type equipment structure, is made by aluminum alloy system section bar, and is provided with end frame sealing band 8.Connection box 3 is also made by aluminum alloy system section bar, which is provided with end frame sealing band 10 and links latch 9.

The utility model embodiment is installed on the windscreen framework at railroad car bodywork two ends, and when two cars connection was hung, by the binding latch 9 on the connection box 3 windscreen of two cars being locked was one, finishes flexible, close knot, heat insulation, sound-deadened function.In the present embodiment, invagination paulin 4, roll over paulin 5 outward and adopt the pressings of import rubber cord fabric to make, middle part adaptor union 7 is crimped on each " ∪ " type ring coupling end together; Two end connectors 6 link together aluminum alloy end frame 1, aluminum alloy connection box 3 and folding paulin 2 respectively.

In the train operation, the crooked radian of " ∪ " type ring is done adaptations with concrete running state under invagination paulin 4 and the outer folding paulin 5, and it is 42dB that its meter is advised sound reduction index.
