一种挖掘机管路布置结构及挖掘机
By adjusting the arrangement of the excavator's hydraulic cylinder lines, the bottom axes of the boom cylinder lines and bucket cylinder lines on the boom side are made parallel to and perpendicular to the upper surface of the boom, and then fixed with fasteners. This solves the problem of interference between the hydraulic cylinder lines and the breaking lines, and improves the excavator's applicability.

AI Technical Summary
There is a slight interference problem between the hydraulic cylinder lines on the upper surface of the existing excavator boom and the added crushing lines when the boom is raised to near its upper limit position.
The hydraulic cylinder lines of the excavator are arranged such that the bottom axes of the stick cylinder line and the bucket cylinder line on one side of the boom are parallel to each other and perpendicular to the upper surface of the boom, and the bottom axes of the stick cylinder line and the bucket cylinder line on the other side are also parallel to each other and perpendicular to the upper surface of the boom. They are fixed to the boom by fasteners, and some lines are provided with bends to move away from the upper surface of the boom.
This effectively avoids interference between the hydraulic cylinder pipeline and the crushing pipeline, improving the excavator's applicability.
