A kind of equipment and method for spraying metal paint on railway rail surface

Abstract

The invention provides a device for spraying a metallic paint on a railway rail surface and a method for spraying the metallic paint. The device comprises a small rail car, a generator, a power device, a spray gun, a metallic paint can, an air pump and a rust removing device. The method comprises the steps of firstly, removing impurities like rust adhering to the rail surface of an original railway rail through the rust removing device; and directly spraying the metallic paint in the metallic paint can to the rail surface of the railway rail through the spray gun, so as to form an electroconductive anodic protective layer on the rail surface of the railway rail.

Description

Technical field [0001] The invention relates to the field of railway track spraying, in particular to a device for directly spraying metal paint on the rail surface of a steel rail and a method for spraying metal paint. Background technique [0002] The rail is an important carrier for the transmission of railway signals. When a train or vehicle passes through a certain section, the wheels and axles of the vehicle are used to form a short circuit between the two rails, and the short-circuit signal is fed back to the signal center to ensure that the only vehicle entering the section Sex. However, in some special sections of the station, the track surface is rusted due to the infrequent or infrequent running of the vehicle. When the vehicle passes through the section, the short circuit signal cannot be generated, that is, the track circuit is poorly shunted, which causes Unsafe factors in railway transportation can easily cause malignant accidents. How to avoid poor track circuits...

AI Technical Summary

Problems solved by technology

However, in some special sections of the station, the rail surface is rusted due to non-traveling or infrequent traffic. When the vehicle passes through this section, a short-circuit signal cannot be generated, that is, the track circuit is not well shunted, which results in Unsafe factors in railway transportation can easily cause serious accidents. How to avoid poor track circuit shunting is an important guarantee for railway operation safety

In the prior art, such as arc spraying aluminum, due to the heavy spraying equipment, complicated spraying construction process, high equipment cost, and the need for large-scale crane transportation, it is impossible to carry out spraying construction with convenient and fast transportation equipment in some mountainous areas, high roadbeds, road cuttings, etc. , resulting in poor track circuit shunting in some sections and cannot be solved
