Abstract
The invention discloses a high-temperature-resistant anti-splashing hydraulic hose which comprises a hydraulic hose body (1) and metal pipe joints (2) installed at the two ends of the hydraulic hose body (1). A high-temperature-resistant protection cover (3) is arranged outside the hydraulic hose body (1), the two ends of the protection cover (3) are fixed to the metal pipe joints (2) through locking hose clamps (4) respectively, and the protection cover (3) is provided with an oil outlet (5). According to the high-temperature-resistant anti-splashing hydraulic hose of the special structure, the high-temperature-resistant silica gel sleeve preventing hydraulic oil from splashing is arranged outside the hydraulic hose, once the hydraulic hose cracks and hydraulic oil splashes, high-pressure hydraulic oil at the cracking position splashes to the silica gel sleeve on the outer layer of the hydraulic hose firstly, pressure of high-pressure hydraulic oil is released, then hydraulic oil flows to the oil outlet and flows to the outside of the protection cover in a low-pressure overflowing mode at the oil outlet, the phenomenon of a fire caused by the facts that the hydraulic hose directly splashes hydraulic oil to outer space at the cracking position and pressure of high-pressure hydraulic oil is released is avoided, and production security is improved.
Description
Technical field
The present invention relates to hydraulic transmission technology in field of metallurgy, especially relate to the high temperature resistant antispray hydraulic hose in a kind of hydraulic transmission.
Background technique
Hydraulic transmission is because its good characteristic is widely used in industrial production, especially on metallurgical hot-rolled steel section and strip production line.On these production lines, because the motion of milling train and other technique supplementary equipment is many and act frequently, so most motions all adopt hydraulic transmission.Yet, these adopt hydraulicdriven mechanism working near under the environment of red steel (i.e. 1000 ℃ of left and right high temperature rolled pieces), in red steel rolling process, once the feed liquor force feed flexible pipe of transmission fluid cylinder pressure or go out hydraulic oil flexible pipe and cracking occurs and spraying liquid force feed, to probably cause hydraulic oil to catch fire, and cause thus other facility of milling train (as cable, hydraulic valve platform and oil pipe etc.) and catch fire, the structural representation of existing hydraulic hose is structure as shown in Figure of description 1.For preventing that cracking splash from appearring in hydraulic hose, the method generally adopting is at present to shorten the online life cycle of hydraulic hose.
Yet, by the research of oil hydraulic cylinder hydraulic hose generation cracking phenomena is learnt, in actual production process, conventionally there is many factors can cause, during oil hydraulic cylinder hydraulic hose normal service life, cracking oil-spraying occurs: 1. hydraulic hose has in use been subject to unnecessary device shock, causes thus hydraulic hose surface or pipe joint place impaired; Be subject to the restriction of working space, oil hydraulic cylinder hydraulic hose is used suppressing under strength state, and after using certain hour, flexible pipe cracking easily appears in hydraulic flexible pipe joint place; 2. there is in process of production larger vibration in oil hydraulic cylinder and hydraulic hose thereof, causes thus hydraulic hose its joint after using certain hour easily to occur flexible pipe cracking; 3. the making quality of hydraulic hose and hose coupling existing problems, cause hydraulic hose in normal service life, to occur CRACKING ACCIDENT etc.Hence one can see that, the oil spout of oil hydraulic cylinder hydraulic hose cracking is the problem that is difficult to avoid in process of production, even if shorten the online life cycle of hydraulic hose, be also difficult to avoid hydraulic hose that the problem of cracking splash occurs, therefore, also be difficult to avoid the ignition issues being caused by hydraulic hose cracking, not only to operator, bring potential safety hazard, also to production, bring economic burden simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high temperature resistant antispray hydraulic hose for problems of the prior art, its objective is and effectively avoid after hydraulic hose cracking, fire problem because the splash of hydraulic oil causes, improves the Security of producing.
Technological scheme of the present invention is this kind of metallic pipe coupling that high temperature resistant antispray hydraulic hose comprises hydraulic hose and is arranged on hydraulic hose two ends; the outside of described hydraulic hose is provided with resistant to elevated temperatures safety cover; the two ends of safety cover are fixed on metallic pipe coupling by locking throat hoop respectively, and described safety cover is provided with oil outlet.
Described oil outlet is positioned at the middle part of safety cover.
As a preferred embodiment of the present invention, described oil outlet is on safety cover, and along the external peripheral surface of safety cover, breach is set.
Described breach has one at least, and breach is half cycle or all-round.
When described breach has more than two, a plurality of breaches are parallel to each other and are distributed on the circumference of safety cover.
As another kind of preferred version of the present invention, described oil outlet is that several oil outlets are set on the circumference of safety cover.
Several described oil outlets are evenly distributed on the circumferential surface of safety cover.
The internal diameter of described safety cover is than the large several millimeters of the external diameter of hydraulic hose.
Described safety cover is the silica gel sleeve pipe with resistance to high temperature.
This kind of high temperature resistant antispray hydraulic hose with said structure has the following advantages:
1. this kind of high temperature resistant antispray hydraulic hose puts a high temperature resistant silicon gum cover pipe that prevents hydraulic oil splash outward by the hydraulic hose conventional, and set out hydraulic fluid port at the middle part of silica gel sleeve pipe, and the internal diameter of safety cover is larger than the external diameter of hydraulic hose, once hydraulic hose, there is cracking oil spout, the high pressure liquid force feed at cracking place first splash to the outer field silicone tube of hydraulic hose and obtain release, then by hydraulic hose and silica gel sleeve pipe clearance channel flow to the oil outlet that silicone tube middle part arranges, hydraulic oil flows to outside the silica gel sleeve pipe of hydraulic hose in the excessive mode of low pressure herein, the fire phenomena of having avoided hydraulic hose directly also to cause thus to space outerpace splash release at its cracking place, improved the Security of producing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of hydraulic hose in prior art.
Fig. 2 is the first structural representation of the present invention.
Fig. 3 is the second structural representation of the present invention.
In Fig. 1-3,1: hydraulic hose; 2: metallic pipe coupling; 3: safety cover; 4: locking throat hoop; 5: oil outlet.
Embodiment
Fig. 1 is the structural representation of hydraulic hose in prior art, in actual use, once the feed liquor force feed flexible pipe of transmission fluid cylinder pressure or go out hydraulic oil flexible pipe and cracking occurs and spraying liquid force feed, to probably cause hydraulic oil to catch fire, and cause thus other facility of milling train as cable, hydraulic valve platform and oil pipe etc. catch fire, to production, bring potential safety hazard.
Fig. 2 is the first structural representation of the present invention, and Fig. 3 is the second structural representation of the present invention.From structure shown in Fig. 2, Fig. 3; this kind of metallic pipe coupling 2 that high temperature resistant antispray hydraulic hose comprises hydraulic hose 1 and is arranged on hydraulic hose 1 two ends; the outside of hydraulic hose 1 is provided with resistant to elevated temperatures safety cover 3; the two ends of safety cover 3 are fixed on metallic pipe coupling 2 by locking throat hoop 4 respectively; and described safety cover 3 is provided with oil outlet 5; and oil outlet 5 is positioned at the middle part of safety cover 3, safety cover 3 is the silica gel sleeve pipes with resistance to high temperature.
