Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary operations for detecting steel rails of railway engineering vehicles, and particularly relates to a bogie with a function of blowing dust on the rail surface. Background Art

[0002] At present, with the rapid development of high-speed railways, the operating speed and mileage of high-speed trains continue to break through. To ensure the safety of trains running on railways, it is necessary to conduct daily inspections on the condition of steel rails, which puts higher and higher requirements on steel rail detection. It is necessary to accurately and efficiently detect the damage of the line steel rails and provide damage data for the maintenance department to repair the line, so as to improve the line maintenance efficiency and reduce potential line safety hazards. However, water, dust, particulate matter or iron filings scattered on the upper surface of the steel rail have an inherent impact on the detection of steel rail surface defects. Defects in some areas of the top surface of the steel rail cannot be effectively detected and evaluated, with obvious detection blind spots, affecting the operation accuracy of detection equipment and posing a greater safety risk. Therefore, it is necessary to clean the dust, particles, iron filings, water and other contaminants on the rail surface before steel rail detection. Content of the Utility Model

[0007] Further improvement lies in that: the air intake pipe is made of rubber, and the air outlet pipe is made of stainless steel pipe.

[0008] A further improvement lies in that the upper end of the air intake pipe is connected to the main reservoir pipe of the vehicle through a taper thread joint, and the lower end of the air intake pipe is connected to the air outlet pipe through a tee.

[0009] A further improvement lies in that the upper end of the tee is connected to the air intake pipe through a joint assembly, and the left and right ends of the tee are respectively connected to the air outlet pipe through ferrule and ferrule nuts.
