Automatic fuel injection system for train rails

The invention relates to an automatic fuel injection system applied to a train railroad track, in particular to a non-contact sensing technology, which is a system for automatically injecting oil lubrication and cooling equipment through sensing control to ensure the safety of the system. The efficacy of life and its inventors for its innovative applications.

According to the mechanism, the mechanical components are combined in a specific manner, and the movement of one or several mechanical components is forced according to the law formed by the combination, forcing other mechanical components to generate a motion that can determine the expected, the combination is called For the institution. However, friction must occur in the relative motion of the machine, and friction exists between the two interfaces with relative motion (dynamic friction), or there is no relative motion between the two interfaces but there is a tendency to move relative to each other (static friction); Most of them will want to reduce the friction, such as the lubrication of mechanical surfaces or bearings, because the friction not only causes the mechanical energy to generate heat, but also causes surface wear and hinders or slows down the movement.

However, in order to reduce the friction, the most common is to inject or inject oil between the two interfaces to produce a lubricating effect, and at the same time, to reduce the high temperature generated by the friction. Like the machining machine (such as: lathes, milling machines, sawing machines, grinding machines and planers, etc.), in order to make the machining (cutting) smooth, the cutting fluid is always injected to reduce friction (lubrication), cooling, It protects the tool and increases the surface luminosity of the work; however, this method requires constant uninterrupted supply of oil, so an oil circulation system is required.

Or when the domestic and foreign railways drive through the bends or turns of the track, the wear of the wheels on the curved track and the ballast is very serious, resulting in a greatly reduced service life of the track. The current method is to wear the workers at easy wear and tear. Intermittent manual spraying of oil reduces wear, but it cannot spray oil frequently and in a timely manner, and workers have high labor intensity, field work, poor working environment, poor safety, and low work efficiency. Therefore, there is a research on the CN103738354A rail inner automatic fuel injection lubrication device. This technology mainly installs a pressure oil device on the inner side of the rail against the inner edge of the rail. The oil pressure device is connected to the fuel tank installed on the roadbed through the oil inlet pipe. The fuel oil pipe is connected to a plurality of fuel injectors mounted on the inner side of the rail, and the oil pressure device is a box-shaped support plate. The left end is hinged to a curved plate by a pin shaft, and the middle portion of the pressure plate is opposite to the oil pressure cylinder. The top end is in contact with each other, and the lower end of the pressure plate is hinged to the top of the vibration damper through a pin shaft, and the bottom end of the vibration damper is hinged to the support plate through the pin shaft. When the train passes, the pressure plate is pressed down, so that the high-pressure oil formed in the pressure oil cylinder chamber is sprayed from the fuel injection nozzle to the rail through the oil discharge pipe.

However, the above structure adopts contact type starting, that is, the pressure plate is used to start the injection when the train passes, but the train wheel body is replaced by the contact type except the platen is damaged. There is also a lack of friction damage, and if there is a small stone on the rail that is sprayed onto the pressure plate, it will produce a wrong start message and continue to spray oil. Therefore, this technology has yet to be developed and improved.
