Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a connecting rod structure and an engineering vehicle. Background Art

[0002] Excavator working devices all use centralized lubrication grease hoses, grease steel pipes, oil filling blocks, distributors and other products, all of which are external piping forms in which the pipelines are laid on the outer wall of the box structure. The current centralized lubrication piping design generally has the problem that parts are easily damaged by collision, especially in the connecting rod rocker arm part. The grease oil channel is left in the middle of the connecting rod shaft pin, which reduces the strength of the pin shaft and poses a risk of breakage. When the loader is in operation, the lubrication point rotates axially relative to the boom. If a centralized lubrication configuration is selected, the lubrication pipeline will be twisted and exposed in an easily damaged area when the loader is in operation, posing a risk of damage. If an external filling port is used, the structure will be cumbersome, occupying more space, and the unreasonable layout will make it impossible to connect the automatic lubrication pipeline.
