Abstract

The invention provides an arm support, a method for fixing a hydraulic pipe on the arm support and an operation machine. The arm support comprises at least one knuckle arm, a hard hydraulic pipe, a soft clamping assembly and a hard clamping assembly. The hard hydraulic pipe is arranged in the extending direction of the knuckle arm, and the soft clamping assembly is clamped to at least one of the first end and the second end of the hard hydraulic pipe. The hard clamping assembly is clamped between the first end and the second end of the hard hydraulic pipe; and the soft clamping assembly and the hard clamping assembly are respectively connected with the knuckle arm. According to the hydraulic pipe fixing device, the hydraulic pipe is effectively fixed on the basis of the soft clamping assembly and the hard clamping assembly, the problem that the hydraulic pipe is abraded and moves at the same time in the using process can be avoided to a certain degree, the fixing reliability of the hydraulic pipe is ensured, and the service life of the hydraulic pipe is prolonged.

Description

technical field [0001] The invention relates to the technical field of working machines, in particular to a boom, a method for fixing hydraulic pipes on the boom, and a working machine. Background technique [0002] For work machines with booms such as excavators and pump trucks, luffing cylinders are usually used to control the movement of the boom on the boom. In order to realize the delivery of hydraulic oil to the luffing cylinder, hydraulic pipes are arranged on the boom. [0003] Fixing hydraulic pipes is an important part of piping design. If the hydraulic pipe is not firmly fixed, the hydraulic pipe will easily vibrate or move due to the oil pressure fluctuation of the hydraulic oil in the hydraulic pipe, resulting in the displacement of the hydraulic pipe relative to the boom, which can easily shorten the life of the hydraulic pipe. In order to ensure that the hydraulic pipe remains stable on the boom, the hydraulic pipe must be fixed and the fixing must be perman...
