[0017] In order to better illustrate the content of the present invention, the following is a description with reference to the accompanying drawings and implementation examples:

[0018] have Figure 1 As shown, the utility model discloses a turnout force monitoring and automatic oil lubrication device, including a shell 1, an oil tank 2 is provided inside the shell 1, an oil pump 4 is provided on the oil tank 2, the oil pump 4 is connected to a distributor 10 through an oil pipe 5, the distributor 10 is connected to several oil pipelines 8, and a master controller 7 is also provided in the shell 1.

[0019] Furthermore, the dispenser 10 is provided with a pressure switch 9 .

[0020] Furthermore, the oil pipe 5 is connected to a one-inlet and two-outlet solenoid valve 6 .

[0021] Furthermore, the oil tank 2 is also provided with an oil level sensor 3 .

[0022] Furthermore, the master controller 7 is electrically connected to the pressure switch 9 , the oil pump 4 , and the one-inlet-two-outlet solenoid valve 6 .

[0023] Furthermore, the master controller 7 is also connected to two current transformers (not shown) for collecting the fixed and reverse status of the switch startup.

[0024] Specifically, when the turnout needs lubrication, the oil pump 4 starts and delivers the oil to the distributor 10 through the oil pipe 5, and then the oil pressure in the distributor 10 increases, the pressure switch 9 feedbacks, and then the master controller 7 controls the pump body 4 to close, and then the oil pressure in the distributor 10 pushes the oil into the oil pipe 8 for oil filling.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the technical solutions of the present invention have been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
