Abstract
The utility model relates to a ultra-high pressure steel wire wound hydraulic hose, which is widely applied to construction machinery, mining machinery and hydraulic assembly pipe system; the outside of the tubular hose is orderly provided with an inner rubber sealing layer, a high-strength thick steel wire wound enhancement layer, a middle rubber protecting layer, a high-softness thin steel wire wound enhancement layer, a middle rubber protecting layer, a high-strength thick steel wire wound enhancement layer, a middle rubber protecting layer, a high-softness thin steel wire wound enhancement layer and an outer rubber protecting layer; the utility model adopts high-strength thick steel wire and outer high-softness thin steel wire wound enhancement layer structure, the pressure bearing layer is well concentrated in the inner ring, so that the steel wire can furthest bear the pressure; and the outer high-softness thin steel wire can be bent easily, so that the comprehensive performance of the steel wire wound hydraulic hose is improved; the pulse resistance index is more than 120% of GBT-2003 national standard, which is also more than 120% of ISO international standards; the flexure resistance index can be increased by 30%, and the bend radius can be decreased by 30%.
Description
One, technical field
The utility model relates to a kind of ultrahigh pressure steel wire-wound hydraulic sebific duct, and it is adaptable across being used for hydraulic pressure assembly guard systems such as engineering machinery, mining machinery.
Two, background technique
Existing traditional ultrahigh pressure steel wire-wound hydraulic sebific duct generally adopts 2 layers of structure, 4 layers of structure, 6 layers of structure, all adopts the same specification steel wire; Though it is simple in structure; Easily manufactured. but because structural inadequate natural endowment, anti-pulse poor performance, flexible resistance is not enough, bending radius is big, has a strong impact on reliability, the stability of ultrahigh pressure braided steel wire hydraulic pressure glue; Working life is short, and the maintain and replace frequency is many. have a strong impact on manufacturing efficiency and safety in production such as engineering machinery, coal mine machinery.
Three, the content of model utility
The purpose of the utility model is to the deficiency of existing high pressure wire braid hydraulic hose, and a kind of ultrahigh pressure steel wire-wound hydraulic sebific duct is provided.
The purpose of the utility model realizes like this: it comprises: the thick guiding principle silk of tubulose sebific duct, interior glue sealing layer, high strength twines that enhancement layer, highly-flexible finer wire twine enhancement layer, outer compound protective layer is formed, outside the tubulose sebific duct, being disposed with in glue sealing layer, the thick guiding principle silk of high strength twine enhancement layer, middle compound protective layer, highly-flexible finer wire twine enhancement layer, middle compound protective layer, the thick guiding principle silk of high strength twine enhancement layer, middle compound protective layer, highly-flexible finer wire winding enhancement layer and outside compound protective layer; The steel wire winding direction that the thick guiding principle silk of described high strength twines enhancement layer and highly-flexible finer wire winding enhancement layer is opposite.
The utility model ultrahigh pressure steel wire-wound hydraulic sebific duct; Adopt the powerful heavy wire of floor height; Outer highly-flexible finer wire structure with the reasonable inner ring that concentrates on of bearing course, can make the steel wire pressure-bearing perform to maximum; And outer highly-flexible finer wire is beneficial to bending, makes the combination property of steel wire-wound hydraulic sebific duct be able to promote; It can obviously improve liter with the pulse performance; Anti-pulse feature index can reach more than 1.2 times of GBT-2003 GB set quota; Also reached more than 1,2 times of ISO international standard set quota, the flexible resistance index can improve 30 percent, and bending radius can dwindle 30 percent.
Four, description of drawings
Accompanying drawing 1 cuts open figure for the utility model ultrahigh pressure steel wire-wound hydraulic sebific duct half one.

Five, embodiment
Come the utility model done below in conjunction with accompanying drawing and embodiment and describe in further detail:
With reference to accompanying drawing; The utility model ultrahigh pressure steel wire-wound hydraulic sebific duct; It comprises: the thick guiding principle silk of tubulose sebific duct 1, interior glue sealing layer 2, high strength twines that enhancement layer 3, highly-flexible finer wire twine enhancement layer 4, outer compound protective layer 6 is formed, tubulose sebific duct 1 outside, being disposed with in glue sealing layer 2, the thick guiding principle silk of high strength twine enhancement layer 3, middle compound protective layer 5, highly-flexible finer wire twine enhancement layer 4, middle compound protective layer 5, the thick guiding principle silk winding of high strength enhancement layer 3, middle compound protective layer 5, highly-flexible finer wire winding enhancement layer 4 and outside compound protective layer 6; It is opposite with the steel wire winding direction that the highly-flexible finer wire twines enhancement layer 4 that the thick guiding principle silk of said high strength twines enhancement layer 3; On sebific duct 1, form the netted protective layer of multilayer indirectly; Glue sealing layer 2 is 669 oil resistant rubbers in described; In compound protective layer 5 are 665 adhesive glues, outer compound protective layer 6 is 575 oil resistants and wait glue.
Claims (2)
1. ultrahigh pressure steel wire-wound hydraulic sebific duct; It comprises: the thick guiding principle silk of tubulose sebific duct (1), interior glue sealing layer (2), high strength twines enhancement layer (3), highly-flexible finer wire and twines enhancement layer (4), middle compound protective layer (5), outer compound protective layer (6) and form, and it is characterized in that: tubulose sebific duct (1) outside, being disposed with in glue sealing layer (2), the thick guiding principle silk of high strength twine enhancement layer (3), middle compound protective layer (5), highly-flexible finer wire twine enhancement layer (4), middle compound protective layer (5), the thick guiding principle silk winding of high strength enhancement layer (3), middle compound protective layer (5), highly-flexible finer wire winding enhancement layer (4) and outside compound protective layer (6).
