Abstract
The utility model relates to a rolling stock air spring snow prevention cover which comprises an annular cover body formed through enclosure of a rubber air bag. The rubber air bag comprises an inner inserting end and an inserted end matched with the inner inserting end. Connecting threading holes are formed in connecting seams where the inner inserting end and the inserted end coincide with each other. The connecting threading holes are connected through a connecting pull strap. A protective layer is arranged on an outer ring of the annular cover body. The rolling stock air spring snow prevention cover is further provided with a cycle valve. The rolling stock air spring snow prevention cover has the advantages that the snow prevention cover is arranged to be of a connected annular structure, the inner inserting end and the inserted end are arranged, the connecting threading holes are formed in the connecting seams at the two ends and connected through the connecting pull strap, and the snow prevention cover surrounds an air spring and plays a role in snow prevention and protection after being inflated. The rolling stock air spring snow prevention cover is simple in structure and convenient to disassemble and assemble, does not affect the operation of the air spring, and blocks the accumulation of ice and snow.
Description
Technical field
The utility model relates to a kind of protecting component that guarantees rolling stock snow day traffic safety, a kind of snow-proof cover for the protection of air bellow specifically.
Background technology
The damping air spring of the high-speed railway locomotive that now moves, and there is the gap of certain angle between car body, snow day will be piled up ice and snow at this position, particularly in the northern area of China winter through snowing a great deal, the damping spring of locomotive often, because of the icing and frozen damping effect that loses after snow melting, threatens traffic safety greatly.
Existing air bellow snow-proof cover is thermal shrinkage type snow-proof cover outer by pyrocondensation and that the pyrocondensation internal layer forms, and closely wraps up spring.When but it uses, the used for rolling stock thermal-shrinkage snow protection enclosure must be entered protected air bellow, then heat shrink, play the fixed protection effect.It has certain defect: troublesome poeration while 1, using, must install under the condition of heating; 2, must be to install when rolling stock connects, and be installed as disposable, as bad in the heat shrink effect or installation site is improper, the snow-proof cover that can only renew pyrocondensation again; 3, can not take off after the installation, can only meet the temperature condition of severe cold in winter,, if, because temperature is higher, certainly will change the performance of snow-proof cover summer, can affect the operation of vehicle.
The utility model content
According to above-mentioned weak point, the purpose of this utility model is to provide that a kind of snow defence is effective, the snow-proof cover of easy accessibility.
For achieving the above object, the technical solution of the utility model is: a kind of rolling stock air bellow snow-proof cover, it comprises the ring-type cover body that is surrounded by rubber pneumatic bag, rubber pneumatic bag comprises interior insertion end and with interior insertion end is complementary, is inserted into end, hold the connecting sewing place that coincides to be provided with the connection through wires hole in interior insertion end with being connected, described connection through wires hole is connected by connecting pull strap; Outer ring at the ring-type cover body is provided with protective layer; Also be provided with tire tube valve on snow-proof cover.
Preferably: the described snow-proof cover outside is provided with fixing outer nib.
Preferably: described protective layer is the impregnation cord, and with the rubber pneumatic bag sulfuration, is integrated.
The beneficial effects of the utility model are: the annular shape structure that snow-proof cover is arranged to be connected; by being provided with interior insertion end and being inserted into end; and connecting sewing place, two ends is provided with the connection through wires hole; be connected by connecting pull strap; be looped around on air bellow, by playing the effect of snow defence protection after inflation.This snow-proof cover is simple in structure, and easy accessibility neither affects air bellow work and blocked again the accumulation of ice and snow.

The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.
Rolling stock air bellow snow-proof cover as shown in Figure 1 as can be known, it comprises the ring-type cover body that is surrounded by rubber pneumatic bag 1, described rubber pneumatic bag 1 comprise interior insertion end 7 and with interior insertion end 7 be complementary be inserted into the end 9, hold 9 connecting sewing that coincides 4 places to be provided with connection through wires hole 6 in interior insertion end 7 with being connected, described connection through wires hole 6 is connected by connecting pull strap 5; Be provided with protective layer 2 in the outer ring of ring-type cover body; Also be provided with tire tube valve 3 on described snow-proof cover.The snow-proof cover outside is provided with fixing outer nib 10.Protective layer is the impregnation cord, and with air bag sulfuration, is integrated, and increases the resistance performance of snow-proof cover, prevents in the high-speed cruising process that the foreign material such as stone cause damage to snow-proof cover.And protective layer is not set in the snow-proof cover inboard, this be because, the inboard of snow-proof cover need to keep certain elastic strength, soft durometer is suitable, air bellow does not does not wear and tear.
Shown in Figure 3 is the split generalized section of protective cover plug-in type connecting bridge, during use, snow-proof cover is surrounded around air bellow 13, interior insertion end 7 is inserted and is inserted into end 9, form and connect the plug seam, and will connect pull strap 5 and be through to connect in through wires hole 6 and fix, inflate in from tire tube valve 3 toward snow-proof cover, snow-proof cover slowly expands, with air bellow 13 parcels, as shown in Figure 4.In addition, the fixing outer nib 10 of snow-proof cover need to be fixed between car body metal parts 12, increase stability and the safety of snow-proof cover, the erection plan of snow-proof cover as shown in Figure 2.
