Problems solved by technology

Although this can solve the problem of how to judge whether the train car is moving in a straight line or a curve to a certain extent, the implementation is very complicated
One is that because the railway line is long, it is a very large project to collect and record all the tracks of all the railways, and the continuous updating of the railways will also change the shape of the tracks. If the records are not updated in time, it will lead to wrong judgments ; Second, there are many management departments involved in the difficulty of on-site maintenance of equipment

Embodiment 1

[0086] Such as Figure 5 As shown, the fuel injection device includes a fuel injector 30 , a control system 20 and a detection device 10 . The detection device 10 is electrically connected to the control system 20 and can transmit electrical signals to each other. The fuel injector 30 is electrically connected to the control system 20 .

[0087] The control system can adopt electronic computer or industrial computer.

[0088] Figure 6 It is a schematic diagram of the principle of the fuel injection device control method in the present invention. Such as Figure 6 As shown, the fuel injector includes an air compressor, an oil storage tank and a nozzle. The air compressor is respectively connected with the two oil storage tanks through the air duct, and the high-pressure gas produced by the air compressor can be filled into the oil storage tank. The oil storage tank is communicated with the nozzle through a grease pipe. The fuel injector is provided with an opening towar...

Embodiment 2

[0102] It differs from Embodiment 1 in that the structure of the fuel injector is different. Such as Figure 15 As shown, the fuel injector includes a fuel storage tank 302 , a fuel injection pipe 305 and a fuel pump 306 . The oil pump 306 is disposed in the oil storage tank 302 . The oil pump 306 communicates with the oil injection pipe 305 . When the oil pump 306 is in operation, the lubricating oil in the oil storage tank 302 can be sprayed to the wheel rim through the oil injection pipe 305 . The oil pump 306 is electrically connected to the control system 20 . The control system 20 can control the operation of the oil pump 306, and can control the power of the oil pump 306, so as to control the amount of fuel injection. All the other structures are the same as in Example 1.

Embodiment 3

[0104] Figure 16 It is a front view of the internal structure of the housing of Embodiment 3. Such as Figure 16 As shown, the difference between this embodiment and Embodiment 1 lies in the structure of the transmission amplification device. The transmission amplification device in this embodiment includes a third gear 41 , a fourth gear 51 and a transmission chain 45 . The third gear 41 , the fourth gear 51 and the transmission chain 45 are all installed in the inner cavity 1 of the housing 1 . Both the third gear 41 and the fourth gear 51 are circular gears. The third gear 41 is mounted on the first rotating shaft 2 . The third gear 41 can rotate with the first rotating shaft 2 . The fourth gear is rotatably mounted on the housing 1 through the second rotating shaft 6 . The contact piece 7 is installed on the fourth gear 51 . The third gear 41 and the fourth gear 51 are connected in transmission through a transmission chain 45 . All the other structures are the sam...

Abstract

The invention discloses a control method for an oil injection device of a track train, which is characterized by comprising a detection and judgment step and an oil injection step, wherein whether the track train is in a curvilinear motion state is detected and judged in the detection and judgment step; and in the oil injection step, more oil than that in the case that the train is in a straight operation state is sprayed to wheels when the track train is detected to be in the curvilinear motion state. In the control method provided by the invention, whether the train is in the curvilinear motion state is detected in real time. Wheel track can be lubricated, and wheel track wear can be reduced; and waste caused by over oil injection or serious wheel track wear caused by less oil injection can also be avoided.

Description

technical field [0001] The invention relates to a control method of an oil injection device of a rail train, an oil injection device, a rail train and a rail locomotive. Background technique [0002] The track of the railway consists of two rows of steel rails arranged in parallel. Each train locomotive or car bottom is equipped with multiple pairs of wheelsets. Each wheel set includes at least two wheels, and each wheel is supported on a row of steel rails. Existing railway lines often span thousands of kilometers or even tens of thousands of kilometers. Because the terrain of the railway crossing range changes greatly, the trajectory of the railway must be adjusted accordingly. In some areas, the railway is a straight line; in some areas, the railway is set in a curve. In China, the track changes of railways are more diverse. The shape of the railway track is various, which determines that the running track of the train includes both a straight track and a curved trac...
