[0019] See also Figure 1-3 The utility model provides an embodiment of an automatic oiling device for railway tracks, comprising a support frame 1, a driving wheel group 8 being provided on the front side of the support frame 1, and a driven wheel group 3 being provided on the rear side of the support frame 1; an oil storage tank 6 is also provided on the support frame 1, and the oil pump inside the oil storage tank 6 pumps the oil into an air pressure tank 5, the air pressure tank 5 is connected to a nozzle assembly 36 provided on the driven wheel group 3 through a delivery pipe 7, and an electromagnetic valve 9 is further provided between the delivery pipe 7 and the nozzle assembly 36; the nozzle assembly 36 includes a protective cover 32, a connecting pipe 37 installed on one side of the protective cover 32, and the other side of the protective cover 32 is connected to a nozzle 31.

[0020] In summary, after the oil pump inside the oil storage tank 6 pumps the oil to the air pressure tank 5, when the oil pressure inside the air pressure tank 5 reaches a predetermined value, the oil pump is shut down, thereby reducing the frequency of starting and stopping the oil pump to protect the oil pump. Then, by opening and closing the solenoid valve 9, the oil is sprayed and shut down, thereby reducing the frequency of starting and stopping the oil pump inside the oil storage tank 6. Based on this, the device utilizes the opening and closing of the solenoid valve 9 to enable the spray head 31 to effectively spray the oil to the sleeper fasteners and sleeper bolts, thereby extending the service life of the oil pump and reducing oil waste. Among them, the air pressure tank 5 is also provided with an electric contact pressure gauge, which uses the electric contact pressure gauge to obtain the internal pressure of the air pressure tank 5 in real time and sends the pressure signal to the controller, which uses the controller to complete the starting and stopping of the oil pump inside the oil storage tank 6.

[0021] In addition, the protective cover 32 can prevent the oil sprayed from the nozzle 31 from splashing onto the upper surface of the rail. The solenoid valve 9 is preferably a remote-controlled solenoid valve. At this time, the user can hold the remote control to open and close the solenoid valve 9.

[0022] Furthermore, since the driving wheel set 8 and the driven wheel set 3 both include a wheel frame 30, and the wheel frame 30 rolls on the track via the provided rollers 35, the device can move along the rails.

[0023] Furthermore, since the wheel frame 30 of the driving wheel group 8 is also provided with a motor 4, and the motor 4 causes the roller 35 on the driving wheel group 8 to rotate, the device can automatically move on the rails.

[0024] In addition, since a generator 2 is also provided on the support frame 1, power can be provided for the device, wherein the generator 2 is preferably a diesel generator.

[0025] In summary, the motor 4 drives the roller 35 to rotate, thereby allowing the device to move along the rails while simplifying its structure. In particular, the device has its own power generation device, thereby extending its working time and allowing the device to spray more rail fasteners and rail sleeper bolts.

[0026] Building on the above solution, since both sides of the protective cover 32 are provided with pressure strips 34, which are movably connected to the protective cover 32, the pressure strips 34 can be used to secure the cloth sheet to both sides of the protective cover 32. This can further reduce oil splashing; secondly, when the cloth sheet passes through the sleeper fasteners and sleeper bolts during equipment movement, the oil contaminated on the cloth sheet can be re-applied to the sleeper fasteners and sleeper bolts. Specifically, bolts are passed through the pressure strips 34 and connected to the protective cover 32, thereby securing the cloth sheet to the protective cover 32.

[0027] In order to facilitate the assembly and maintenance of the equipment, the protective cover 32 is movably connected to the connecting pipe 37 through a first connecting piece 38, wherein the outer wall surface of the connecting pipe 37 has a thread, and is connected to it by the first connecting piece 33 to fix it on the wheel frame 30; therefore, the nozzle assembly 36 can be disassembled through the first connecting piece 38, and conversely, it is also convenient to install the nozzle assembly 36 on the connecting pipe 37; based on this, the nozzle assembly 36 is easy to disassemble and assemble, so as to facilitate the installation and replacement of the nozzle assembly 36.

[0028] Specifically, the first connecting member 33 and the second connecting member 38 are preferably nuts. There are two second connecting members 38. After the connecting tube 37 passes through the wheel frame 30, one is located on the upper surface of the wheel frame 30, and the other is located on the lower surface of the wheel frame 30. By rotating the two first connecting members 33, the connecting tube 37 can be securely fixed to the wheel frame 30. Similarly, the other end of the connecting tube 37 is also connected to the delivery tube 7 via the second connecting member 38.

[0029] Furthermore, the driving wheel group 8 and the driven wheel group 3 are both movably connected to the support frame 1. Specifically, they are connected to the wheel frame 30 after passing through the support frame 1 by bolts, thereby facilitating the assembly and disassembly of the driving wheel group 8, the driven wheel group 3 and the support frame 1.

[0030] In addition, since the nozzle 31 is a fan-shaped nozzle, the spraying range of the oil can be expanded to ensure that the oil can completely cover the sleeper fasteners and sleeper bolts.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
