Embodiment Construction

[0014] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0015] Such as Figure 1-3 As shown, it is the best embodiment of the present invention, a hydraulic cylinder telescopic oil pipe, including a top end cover 1, a cylinder barrel 2, a hollow piston rod 3, an oil pipe 4 in a cylinder, a piston 5, a bottom end cover 6 and an oil equalizing pipeline 7. The top end cap 1 and the bottom end cap 6 are respectively fixedly arranged on the front and rear ends of the cylinder 2. The bottom end cap 6 is a cylindrical structure, and a blind hole 61 is opened on the inner end surface of the bottom end cap 6 along the axis. The outer circumference of the end cover 6 is provided with an oil inlet hole B62 and a bottom oil h...

Abstract

The invention relates to the technical field of hydraulic equipment, in particular to a hydraulic cylinder type telescopic oil pipe. One end of the telescopic oil pipe is fixed, the other end of the telescopic oil pipe is fixedly connected with a motion platform, a port of the fixed end is connected with an oil source, a port of the movable end is connected with an oil utilization component on themotion platform, in the moving process of the motion platform, the position of an oil pipe connector is kept fixed relative to the oil utilization component on the platform, motion platform oil supply is free of hoses, the bending space needing to be reserved in the hose motion process can be saved, system rigidity is improved, and the problem about fatigue aging caused by hose bending in the motion process is solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a hydraulic cylinder telescopic oil pipe. Background technique [0002] The existing oil pipes connecting the moving parts and the fixed parts are mostly hoses. During the movement of the moving parts, the hoses will bend in different degrees with the change of the distance between the moving parts and the fixed parts. During the design and construction process , It is necessary to leave enough space for the deformation of the hose; at the same time, because the hose is often bent, it is prone to fatigue damage, which affects the operation of the system. [0003] Therefore, in response to the above requirements, designing a retractable oil pipe with a small reserved space and long fatigue life is of great significance and engineering application value for reducing the volume of the hydraulic system, increasing reliability, and improving system stability.
