Description
Technical Field
The utility model relates to an earth and stone side machinery specifically indicates an excavation hose.
Background
The excavator is a main variety of earth and stone machinery, has two functions of excavation and earthwork loading and transportation, and is mainly used in the industries of capital construction projects, irrigation and water conservancy, mining and the like. The oil suction hose is an important connecting piece of an oil suction pipeline of an excavator hydraulic system, and the use requirement of the oil suction hose on the excavator is mainly embodied in four aspects: firstly, the oil resistance and the temperature resistance of the oil absorption hose must be considered during design; secondly, the pump is rigidly connected with the engine through a coupler, so that the vibration frequency is high, the amplitude is large, the axial elastic deformation of the oil suction hose is large, and the vibration reduction and buffering performance is good; thirdly, the bearing pressure is high, the radial deformation is small, and the service life is long; fourthly, the installation is convenient. The common oil suction hose in the prior art is mainly made of cloth-sandwiched oil-resistant rubber, an adhesive tape is sandwiched between two rubber layers, the surface of the outermost rubber layer is covered with the adhesive tape, the oil suction hose with the structure is applied to a 6T-level mini excavator, the actual bearing pressure of the oil suction hose is not more than 0.8bar, and the service life of the oil suction hose is generally only 2-3 years. Therefore, the oil suction hose in the prior art cannot meet the requirements of oil suction pipelines of hydraulic systems of excavators of different levels in consideration of the bearing pressure, the service life and the like of the oil suction hose.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming above technical defect, providing an excavation hose, can bear higher system pressure, long service life.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides an excavation hose, includes outer glue film, well glue film and interior glue film, outer glue film and well glue film between be connected the enhancement layer, the enhancement layer constitute with the winding high strength thick steel wire layer of alternative direction by six layers, interior glue film outer wall connection protective layer, the protective layer be located between well glue film and the interior glue film, the inner tube external diameter that interior glue film formed be 72mm, well glue film thickness be 0.6mm, outer glue film thickness be 3.5mm, outer glue film formed outer tube external diameter be 116.2 mm.
Compared with the prior art, the utility model the advantage lie in: the utility model discloses can strengthen the compressive capacity that the hose bore higher system pressure, reduce the impact of the vibration of pump to the oil tank simultaneously to can reduce hydraulic system's turbulent flow, finally improve the life of hose, this kind of hose structure is simpler moreover, low in manufacturing cost.
As an improvement, the outer rubber layer is weather-aging-resistant synthetic rubber.
As an improvement, the middle rubber layer is synthetic rubber which is added in the middle of the reinforced layer and plays a role in adhesion.
As an improvement, the inner rubber layer is synthetic rubber resistant to hydraulic oil.
As an improvement, the protective layer is a layer of voile.

Fig. 1 is a schematic structural diagram of the present invention.
As shown in the figure: 1. outer glue layer, 2, middle glue layer, 3, inner glue layer, 4, enhancement layer, 5, protective layer.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The utility model provides an excavation hose, includes outer glue film 1, well glue film 2 and interior glue film 3, outer glue film 1 and well glue film 2 between connect enhancement layer 4, enhancement layer 4 constitute with the winding high strength thick steel wire layer of alternative direction by six layers, 3 outer wall connection protective layer 5 of interior glue film, protective layer 5 be located between glue film 2 and the interior glue film 3, the inner tube external diameter that interior glue film 3 formed be 72mm, 2 thickness on well glue film be 0.6mm, 1 thickness on outer glue film be 3.5mm, the outer tube external diameter that 1 formation on outer glue film be 116.2 mm.
The outer rubber layer 1 is weather-aging-resistant synthetic rubber.
The middle rubber layer 2 is synthetic rubber which is added in the middle of the reinforced layer 4 to play a role in adhesion.
The inner rubber layer 3 is made of synthetic rubber resistant to hydraulic oil.
The protective layer 5 is a layer of voile.
The utility model discloses when concrete implementation, hydraulic oil flows through in the inner tube that the inner rubber layer formed, and well glue film, enhancement layer and protective layer can improve the axial elastic deformation volume of hose, reduce the impact of the vibration of pump to the oil tank to reduce excavator hydraulic system's turbulent flow, the pipe wall of reinforcing hose bears the compressive capacity of higher system pressure, consequently, has finally improved the life of hose.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
