Satellite car supporting oil cylinder of continuous-type tamping wagon

Abstract

The invention relates to a satellite car supporting oil cylinder of a continuous-type tamping wagon, and the satellite car supporting oil cylinder comprises a cylinder body, a piston rod and a guide sleeve, wherein the guide sleeve and the cylinder body are of a concentric structure, the guide sleeve is a flange-type guide sleeve, a working stroke of the guide sleeve is 43mm, a plain body part of the cylinder body is provided with a bearing, and the guide sleeve is supported by the cylinder body on the plain body part of the cylinder body. In the entire working process, the guide sleeve can be supported by the plain body part of the cylinder body on any stroke position, so that the guiding precision, stability and the sealing performance can be guaranteed, meanwhile the deviation of the movable piston rod in the moving process can be avoided, the extension and retraction stability of the piston rod can be improved, and the piston rod can be prevented from being seized or stopped; and the satellite car supporting oil cylinder has advantages of strong stability, sufficiency in supporting force, good sealing performance, stability in running, safety and reliability in working, high working efficiency and long service life.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machinery equipment, and relates to a satellite trolley supporting oil cylinder of a continuous tamping vehicle. Background technique [0002] Along with the development of my country's railway transportation industry, the tamping machinery and method of my country's railway line ballast are also constantly developing. When the ballast is tamped, its disadvantages are: large power loss, chaotic vibration direction, low work efficiency, which seriously affects the tamping quality, and cannot meet the requirements of modern lines. [0003] The continuous tamping car is a kind of railway maintenance equipment, which can improve the line accuracy and work efficiency, make full use of the "skylight" time, and is a necessary equipment for efficient maintenance of speed-up lines. [0004] The existing continuous tamping vehicle satellite trolley support cylinder has the following disadvantages during u...

Problems solved by technology

[0002] Along with the development of my country's railway transportation industry, the tamping machinery and method of my country's railway line ballast are also constantly developing. When the ballast is tamped, its disadvantages are: large power loss, chaotic vibration direction, low work efficiency, which seriously affects the tamping quality, and cannot meet the requirements of modern lines

[0004] The existing continuous tamping vehicle satellite trolley support cylinder has the following disadvantages during use: first, poor stability, second, insufficient support force, third, poor sealing, fourth, vibration and pause during operation, and poor work. Stable, and at the same time, the stability of the pressure rod is poor, and bending or deformation often occurs during use

[0005] like figure 2 It is a structural schematic diagram of the existing continuous tamping vehicle satellite trolley support cylinder. Since the guide sleeve of the existing continuous tamping vehicle satellite trolley support cylinder is not concentric with the cylinder body, there is a problem of screw connection during the process of processing and installation. If it is loose or there is a gap, it will easily cause the thread of the guide sleeve to damage the static seal O-ring, and this looseness and gap will directly affect the sealing performance, and oil leakage will easily occur, and the poor sealing performance will be greatly reduced. its useful life
