Description

Hydraulic control telescopic arm Technical Field The utility model relates to the technical field of engineering machinery, in particular to a hydraulic control telescopic arm. Background The hydraulic control telescopic boom is a common core actuating mechanism in engineering machinery, and is driven by a hydraulic rod with a core structure, so that the telescopic function of the boom body is realized. The working principle is mainly based on hydraulic transmission, and the arm body is pushed to move through the expansion and contraction of the hydraulic cylinder. In the prior art, in the application of the existing hydraulic control telescopic arm, the hydraulic control telescopic arm usually drives a hydraulic rod to drive a movable arm body to move so as to realize corresponding operation functions, hard particles such as broken stones and gravel are often mixed in the operation environment of a severe environment, the hard particles are easy to splash under the action of external force in the operation process, then the splashed broken stone particles directly impact the surface of a piston rod of an oil cylinder and are attached to the surface of the piston rod of the hydraulic rod, when the hydraulic rod is driven to continuously and frequently stretch, the broken stone particles are easy to be clamped in the stretching part of the hydraulic rod, after the broken stone particles are clamped in the hydraulic rod, the surface of the hydraulic rod is scratched, the sealing structure of the hydraulic rod is damaged, and the leakage phenomenon of the hydraulic system is further caused, so that the maintenance cost and the shutdown time of the hydraulic system are further increased, and the actual application and operation are not facilitated.
