Electric curved rail lubricant coating vehicle

Abstract

The invention discloses an electric curve steel rail lubricating agent coating vehicle which comprises a rail vehicle and a coating device. The coating device comprises a control structure, a lubricating agent container, a lubricating oil pump and a lubricating agent spraying structure. The control structure controls the start action of the lubricating oil pump. The rail vehicle comprises a front axle with a front moving wheel and a rear axle with a rear moving wheel. The front axle is connected with the rear axle through a vehicle body. The front moving wheel and the rear moving wheel are matched with a rail. The rail vehicle and the lubricating oil pump are powered by a direct current power source. The control structure, the lubricating agent container and the lubricating oil pump are arranged above the rear portion of the rail vehicle. The lubricating agent spraying structure is arranged below the rear portion of the rail vehicle. The lubricating agent spraying structure is connected with a shaft box of the rail vehicle and is connected with the lubricating oil pump through an oil spraying pipe. A side spraying nozzle of the lubricating agent spraying structure corresponds to a curve steel rail outer gauge corner. By the adoption of the electric curve steel rail lubricating agent coating vehicle, assembly and disassembly are convenient, rail entering is convenient, coating efficiency is high, and the problem that manual coating is low in efficiency and poor in effect is solved.

Problems solved by technology

[0002] The lubricant mechanical coating method adopted in the prior art is that the vehicle-mounted curved rail lubricating coating device is placed at the tail of the railway passenger train, and lubricating materials such as lubricant or lubricating grease are applied to the corners of the outer strands of the curved rail. In order to achieve the effect of lubricating and reducing friction on the contact friction force surface, reduce the wear of the contact surface, and prolong the service life of the stock rail. Lubricating coating is carried out at the corner. At this time, manual coating operations are required. The efficiency of manual coating is very low, and the coating speed is generally 2km / h. The labor intensity is high, and the coating quality is affected by human factors. unstable

[0003] In addition, the mechanical coating method in the prior art generally adopts the method of spraying lubricant or grease obliquely from the top of the rail, and the lubricant is often sprayed on the top surface of the rail, which may cause locomotives and vehicles to idle and skid At the same time, it is impossible to effectively lubricate the friction parts, which increases the wear of the friction parts, reduces the service life of the rail, and also increases the waste of lubricating materials.

Especially in the driving area where the turning radius of the vehicle is small and the vehicle speed is low, the spraying speed of the lubricant cannot reach the jet flow required for normal spraying. There is less lubricant at the gauge corner of the outer strand of the rail, and the utilization rate of the lubricant is lower, which increases the wear of the friction parts, reduces the service life of the rail, and increases the waste of lubricating materials
