Embodiment Construction

[0044] The present invention will be further described below in conjunction with drawings and embodiments.

[0045] The schematic cross-sectional view of the guide rail of the present invention is as figure 1 As shown in the figure, the unfilled structure surrounded by the black solid line is the main body of the guide rail, 1 indicates the skid surface of the guide rail main body, 2 indicates the braking surface of the guide rail main body, both inside and outside belong to the braking surface, and 3 indicates the overlay layer.

[0046] The preparation method of this rail is as follows:

[0047] (1) Use acetone to clean the residual oil on the welding surface of the F-shaped steel guide rail and the stainless steel protective material, and perform sandblasting and roughening treatment. The abrasive is SiC to remove the attachment, rust and oxide layer on the surface.

[0048] Use jet-suction sandblasting equipment to pre-treat the surface of the substrate by sandblasting. ...

Abstract

The invention discloses a guide rail for magnetic suspension and a preparation method thereof. The guide rail comprises a guide rail body; the guide rail body comprises a brake surface and a sliding surface; a coating layer is a metal coating layer and is arranged on each of the surfaces of the brake surface and / or the sliding surface of the guide rail body, and the metal coating layer is welded on the guide rail body. The guide rail disclosed by the invention has the benefits that as the metal coating layers are arranged on the brake surface or the sliding surface of the guide rail body, the wear resistance and the corrosion resistance of the brake surface and the sliding surface are improved, friction coefficients can be adjusted and controlled according to material components to fit a brake pad and meet the brake standard requirements; the coating layers arranged on the brake surface or the sliding surface of the guide rail can obstruct gas and liquid infiltration paths, so that good shielding protection is provided for protected metal, the corrosion resistance of a magnetic suspension steel rail is increased, and the service life is prolonged.

Description

technical field [0001] The invention relates to a guide rail for magnetic suspension and a preparation method thereof, in particular to an F-type guide rail for medium-low speed magnetic suspension and a preparation method thereof, and belongs to the technical field of rail transportation. Background technique [0002] Medium and low-speed maglev rail transit is a new technology with independent intellectual property rights in my country. The normal speed of maglev trains can reach 90-100km / h. It has high environmental protection, good safety, strong climbing ability, small turning radius, low construction cost and With good operating efficiency and other characteristics, it is suitable for transportation connections between urban areas, short-distance cities and tourist attractions, and can replace light rail and subway. What drives the medium-low speed maglev train is the interaction between the secondary (coil) installed on the train and the primary (aluminum induction pla...
