Description

Wear-resistant fire hose

Technical Field

The application relates to the field of fire-fighting equipment, in particular to a wear-resistant fire hose.

Background

Fire hose is a hose used to transport high pressure water or fire-retardant liquids such as foam. The traditional fire hose takes rubber as a lining, and the outer surface of the traditional fire hose is wrapped by linen braided fabric. The advanced fire hose is made of polyurethane and other polymer materials. At the in-process that uses, can be full of high-pressure rivers in the hosepipe, although the material of this application of fire hose is softer, and weight is lighter, but the in-process that uses is because inside is full of high-pressure rivers, and consequently the weight of hosepipe is very heavy, when the handheld squirt of fireman puts out a fire, can have the friction of relapseing between hosepipe and the ground, consequently can damage the weaving layer of hosepipe, in case the weaving layer damages, then the condition of leaking appears very easily.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the application aims at overcoming the defects of the prior art and provides the wear-resistant fire hose.

The technical scheme is as follows: a wear-resistant fire hose sequentially comprises an inner liner, a first glue layer, an inner woven layer, an outer woven layer and a wear-resistant layer from inside to outside, wherein a second glue layer and a plurality of strip-shaped wear-resistant units extending along the length direction of the hose are arranged between the inner woven layer and the outer woven layer; the strip-shaped wear-resistant unit comprises an arc-surface-shaped strip-shaped unit extending along the length direction of the water hose and a plurality of first strip-shaped convex ribs which are fixed on the outer side of the arc-surface-shaped strip-shaped unit and extend along the length direction of the water hose; and a plurality of second strip-shaped convex ribs extending along the length direction of the water band are arranged on the outer side of the wear-resistant layer.

Preferably, the wear-resistant layer is a polyurethane wear-resistant layer, and the wear-resistant layer and the second strip-shaped ribs are integrally formed.

Preferably, the plurality of second strip-shaped convex ribs are distributed in an annular shape at equal intervals; the number of the second strip-shaped convex ribs is more than or equal to 6.

Preferably, each strip-shaped wear-resistant unit is provided with more than 3 first strip-shaped convex ribs, and the arc-surface-shaped strip-shaped units and all the first strip-shaped convex ribs on the arc-surface-shaped strip-shaped units are integrally formed.

Preferably, the strip-shaped wear-resistant units are made of wear-resistant rubber, and the strip-shaped wear-resistant units are distributed in an annular shape at equal intervals; the number of the strip-shaped wear-resistant units is more than or equal to 4.

Therefore, no matter how the water hose is twisted and rotated, the strip-shaped wear-resistant units can be supported on the ground, and the effect of protecting the water hose is achieved.

Preferably, the inner woven layer and the outer woven layer are aramid fiber woven layers. Thereby obtain the double-deck weaving layer of high strength to provide better protection effect for the hosepipe.

Has the advantages that: the utility model provides a fire hose is owing to have double-deck weaving layer to have the wear-resisting unit of bar between the double-deck weaving layer, a plurality of wear-resisting units of bar are fixed spacing by the second glue film, and the outside has wearing layer and a plurality of protruding muscle of second bar, thereby the hosepipe has fine wear-resisting effect on the whole, thereby life is longer.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Reference numerals: 1, lining layer; 2, a first glue layer; 3 inner braided layer; 4 strip-shaped wear-resistant units; 4.1 arc surface shape strip unit; 4.2 first bar-shaped convex ribs; 5, a second glue layer; 6 outer braided layer; 7, a wear-resistant layer; 7.1 second strip-shaped convex ribs.

As shown in the figure: a wear-resistant fire hose sequentially comprises an inner liner layer 1, a first glue layer 2, an inner woven layer 3, an outer woven layer 6 and a wear-resistant layer 7 from inside to outside, wherein a second glue layer 5 and a plurality of strip-shaped wear-resistant units 4 extending along the length direction of the hose are arranged between the inner woven layer 3 and the outer woven layer 6; the strip-shaped wear-resistant unit 4 comprises an arc-surface-shaped strip-shaped unit 4.1 extending along the length direction of the water hose and a plurality of first strip-shaped convex ribs 4.2 fixed on the outer side of the arc-surface-shaped strip-shaped unit 4.1 and extending along the length direction of the water hose; the outer side of the wear-resistant layer 7 is provided with a plurality of second strip-shaped convex ribs 7.1 extending along the length direction of the water band.

The wear-resistant layer 7 is a polyurethane wear-resistant layer, and the wear-resistant layer 7 and the second strip-shaped convex ribs 7.1 are integrally formed. The second strip-shaped convex ribs 7.1 are distributed in an annular shape at equal intervals; the number of the second strip-shaped convex ribs 7.1 is more than or equal to 6. Each strip-shaped wear-resistant unit 4 is provided with more than 3 first strip-shaped convex ribs 4.2, and the cambered surface-shaped strip-shaped units 4.1 and all the first strip-shaped convex ribs 4.2 are integrally formed. The strip-shaped wear-resistant units 4 are made of wear-resistant rubber, and the strip-shaped wear-resistant units 4 are distributed in an annular shape at equal intervals; the number of the strip-shaped wear-resistant units 4 is more than or equal to 4. The inner woven layer 3 and the outer woven layer 6 are aramid fiber woven layers.
