Steel rail fat edge milling device

Abstract

The invention discloses a steel rail fat edge milling device which comprises a frame, a working part and a supporting wheel, wherein the working part and the supporting wheel are separately mounted ontwo sides of the frame; the working part comprises a walking mechanism, a milling mechanism and a multi-guide wheel clamping mechanism; the walking mechanism and the supporting wheel are separately overlaid on two steel rails; the driving frame moves along the steel rails; the milling mechanism comprises a bottom plate, a milling cutter assembly and an adjusting assembly; the multi-guide wheel clamping mechanism clamps one steel rail and moves along the steel rails along with the frame; the bottom plate is slidably connected to the frame; the milling cutter assembly is mounted at the edge ofone side, facing the steel rails clamped by the multi-guide wheel clamping mechanism, of the bottom plate; and the adjusting assembly is used for adjusting the distance between the bottom plate and the steel rails clamped by the multi-guide wheel clamping mechanism and can fix the position of the bottom plate. The steel rail fat edge milling device disclosed by the invention is skillful in structure, high in degree of automation, more excellent in milling effect, high in milling speed, high in efficiency and longer in service life of a milling cutter. Compared with single-layered milling, reverse quake is smaller, and the structure is more stable.

Description

technical field [0001] The invention relates to a rail fat edge milling device. Background technique [0002] Based on my country's complex terrain and vast land, railways, especially high-speed railways, as an economical and efficient means of transportation that can run through the entire Chinese road, not only meet the needs of people's material and spiritual life, but also promote the development of various ethnic groups in various regions. The exchanges have provided a strong support for the unity of all ethnic groups. Rails are an important tool for railway transportation, and intact rails are the guarantee for the safety of people from one place to another. After the rails have been used for a period of time, rail fat edges will be produced. In order to ensure the safety of railway transportation, the fat edges generated by the rails will be cut off. The existing milling devices are all single-layer milling and the milling position cannot be adjusted, so the applicab...

AI Technical Summary

Problems solved by technology

The existing milling devices are all single-layer milling and the milling position cannot be adjusted, so the applicability is poor. The single-layer milling has high requirements for the milling cutter for the milling work, so the cost is high, and the vibration of the single-layer milling is also large. The components of the guide rail are extremely demanding, the milling speed is slow, and the milling accuracy is not good
