Oil supply system of railway curve line wheel rail lubricating device

Abstract

The invention discloses an oil supply system of a railway curve line wheel rail lubricating device and relates to the technical field of railway maintenance. The system comprises an oil storage tank, a guide sleeve, a hydraulic one-way valve, a piston rod, a driving mechanism, a first oil seal, an oiling device and an oil supply pipe, wherein an oil storage cavity is formed in the oil storage tank; the guide sleeve is fixedly connected with the oil storage tank, and an oil outlet channel is formed in the guide sleeve; the hydraulic one-way valve is fixedly connected with the guide sleeve; the driving mechanism can drive the piston rod to reciprocate between the oil storage cavity and the oil outlet channel; the first oil seal is fixedly connected to the piston rod, and the first oil seal can extrude grease in the oil storage cavity into the hydraulic one-way valve from the oil outlet channel along with movement of the piston rod; and the oil supply pipe is connected between an oil outlet of the hydraulic one-way valve and an oil inlet of the oiling device. The oil supply system is advantaged in that the oil outlet amount can be well controlled, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of railway maintenance, in particular to an oil supply system for a wheel-rail lubricating device on a curved railway line. Background technique [0002] In recent years, with the continuous increase of train speed and axle load, the wear of rails and wheel rims has also increased accordingly. When the rolling stock runs in the curve section, the rail side grinding phenomenon is more prominent, and the maintenance cycle of the wheel set is correspondingly shortened. Wheel rails on curved lines wear quickly. If the wear is too large and not found in time, it will cause serious traffic accidents. In the past, it was time-consuming, laborious and costly to rely on manual inspection and replacement in the construction section. Curved lines have complex terrain and are not suitable for installation of large-scale line maintenance equipment. Patent CN203198977U discloses an oiling device for a rail oiler, includ...

AI Technical Summary

Problems solved by technology

Grease enters the hydraulic check valve under the pressure of the piston rod, and the oil output can be better controlled through the guide sleeve, which saves energy; the grease enters the oiling device after passing through the oil outlet channel, hydraulic check valve, and oil supply pipe in sequence , transported to the wheel rail through the oiling device, it can lubricate the wheel rail of the curved line, which greatly solves the problem of side grinding of the small radius curve of the wheel rail; reduces the strong noise caused by the friction between the train wheel pair and the rail, and protects the Improve the environment; prolong the service life of the curved wheel and rail, greatly ensure the safety of driving, and reduce the waste of manpower and material resources due to the wear and tear of the wheel and rail
