Description

Technical Field

[0001] The utility model relates to the technical field of excavators, in particular to an anti-wear device for a hydraulic hose of an environmentally friendly excavator. Background Art

[0002] An excavator is an earth-moving machine that uses multiple hydraulic cylinders to drive the bucket, digs materials above or below the bearing surface, and loads them into transport vehicles or unloads them to a stockpile. A hydraulic hose connecting the bucket hydraulic cylinder and the hydraulic oil tank is installed between the boom and the dipper arm. The hydraulic hose is used to transport high-pressure hydraulic oil and is generally a soft rubber hose. In order to prevent the hydraulic hose from being worn when the boom and the dipper arm are relatively displaced, an anti-wear device is installed.

[0003] When performing anti-wear treatment on hydraulic hoses, existing anti-wear devices often reduce wear by covering the outer surface with a protective sleeve. However, since it does not have a limiting mechanism, when the boom and the dipper arm are relatively displaced, the external protective sleeve will cause the hydraulic hose to shake or swing greatly. The shaking and swinging can easily cause the dipper arm or the boom to collide and wear. Over time, the protective sleeve is damaged and loses its anti-wear effect on the hydraulic hose. The protective sleeve needs to be replaced, which brings inconvenience to people's use. Therefore, an environmentally friendly anti-wear device for hydraulic hoses for excavators is proposed.
