Description

  The present invention relates to an oil scattering prevention cover. In particular, the present invention relates to an oil scattering prevention cover that covers a hydraulic hose and prevents oil leaking from the hydraulic hose from scattering.

  Conventionally, hydraulic systems are used in construction machines such as power shovels and forklifts, press machines, pressurizers, luggage elevators, and the like. This hydraulic system uses hydraulic pressure as power for operation. A high-pressure fluid produced by a hydraulic pump is sent out by a hydraulic hose, and a piston or a hydraulic motor (generally referred to as an actuator generally) installed at a predetermined place. ) Is a power system that performs work.

  In such a hydraulic system, there is a case where a damaged part such as a tear or a hole occurs in a part of the hydraulic hose that is used over time, or when an object contacts the hydraulic hose during use. There is a risk of fluid (oil) scattering outside the hydraulic hose. In order to prevent such oil scattering, in recent years, an oil scattering prevention cover that covers the outer periphery of the hydraulic hose has been used.

  Such an oil scattering prevention cover has, for example, a cylindrical shape, and is configured to cover the periphery of the hydraulic hose by inserting one end of the hydraulic hose from one opening. Things are known. An oil scattering prevention cover formed in a sheet shape is also known. The sheet-like oil scattering prevention cover is used by winding the hydraulic hose and the oil scattering prevention cover integrally with a binding tool such as a binding band after being wound around the hydraulic hose.

  Conventionally known oil splatter prevention covers exhibit a certain effect from the viewpoint of suppressing oil splattering from the damaged part generated in the hydraulic hose, but more reliably oil splattering. There is a need for further improvements that can suppress the above. For example, when a small pinhole is formed in the hydraulic hose, oil in an extremely high pressure state is ejected from the pinhole, and there is a problem that the ejected oil breaks through the oil scattering prevention cover. It is desired to solve such problems.

  The present invention has been made to contribute to such a demand, and provides an oil scattering prevention cover that can be prevented from being pierced by high-pressure oil ejected from a pinhole formed in a hydraulic hose. For the purpose.

  The object of the present invention is an oil splatter prevention cover that covers the surface of a hydraulic hose, and includes a cylindrical cover body that houses the hydraulic hose therein, and the cover body has a fiber strength of 18 cN / It is achieved by an oil scattering prevention cover characterized by being formed of a fiber material having a dtex of 38 cN / dtex or less and a fiber elastic modulus of 500 cN / dtex or more and 1600 cN / dtex or less.

  Also, the object of the present invention is an oil splatter prevention cover that covers the surface of the hydraulic hose, the sheet-like cover body that is installed by winding the surface of the hydraulic hose into a cylindrical shape, and the hydraulic hose. Fixing means for maintaining a cylindrical winding state of the cover body installed on the surface of the cover body, the cover body having a fiber strength of 18 cN / dtex or more and 38 cN / dtex or less and a fiber elastic modulus This is achieved by a cover for preventing oil scattering, which is formed from a fiber material having a density of 500 cN / dtex to 1600 cN / dtex.

  Since the cover for preventing oil scattering according to the present invention has the above-described configuration, an extremely high strength and high elasticity cover can be obtained, and a pinhole is formed in the hydraulic hose. Even if the oil is ejected, it is possible to effectively suppress the oil from breaking through the oil scattering prevention cover, and the oil can be extremely effectively prevented from scattering to the outside. In addition, since the oil splash prevention cover can be configured with high strength and high elasticity, the impact on the hydraulic hose when it comes into contact with external obstacles is effectively reduced, effectively protecting the hydraulic hose. It is also possible to do.
