[0029] The following combination Figures 1 to 7The steps for using an anti-seizure engine lubrication system in this article are described in detail: in the initial state, the motor 52 starts to run, driving the power shaft 44 to rotate, and the power shaft 44 drives the first transmission shaft 37 to rotate through the transmission bevel gear 71, the planetary gear 39 and the thirteenth bevel gear 38. The planetary gear 39 and the planetary gear shaft 41 are stationary relative to the support frame 42. The first transmission shaft 37 drives the main oil pump 12 to run through the second bevel gear 67, the first bevel gear 66 and the main oil pump shaft 13, so that the lubricating oil starts to flow in the pipeline, the pipeline baffle 17 closes the spare oil channel 200, the sliding shaft 57 is separated from the gear shaft 55, the auxiliary oil pump 25 does not run, and the oil pressure monitor on the left side is The oil pressure in the measuring pipe 46 is greater than the oil pressure in the right oil pressure monitoring pipe 46, causing the film 48 to deform to the right. At this time, the pressure sensor 51 controls the electromagnet 64 through the wire 47 not to start; when the main oil pump 12 is stuck, the main oil pump shaft 13 stops rotating, causing the first transmission shaft 37 to stop rotating. At this time, the planetary gear 39 and the planetary gear shaft 41 start to rotate under the drive of the transmission bevel gear 71, thereby preventing the power shaft 44 from being stuck. At the same time, the oil stops rotating, making the oil pressure in the oil pressure monitoring pipes 46 on both sides equal. At this time, the pressure sensor 51 starts the electromagnet 64 through the wire 47, causing the electromagnet 64 to generate magnetism and drive the magnetic block 62 to slide to the left, causing the sliding shaft 57 and the gear The shaft 55 is meshed, so that the power shaft 44 drives the third transmission shaft 58 to rotate through the fifth bevel gear 53, the sixth bevel gear 54, the gear shaft 55, and the sliding shaft 57, and the third transmission shaft 58 drives the second transmission shaft 28 to rotate through the seventh bevel gear 59 and the eighth bevel gear 61, and the second transmission shaft 28 drives the auxiliary oil pump 25 to start running through the fourth bevel gear 69, the third bevel gear 68 and the auxiliary oil pump shaft 24; at the same time, the second transmission shaft 28 drives the hollow shaft 26 to start rotating through the pawl 72 and the tooth surface 65, and the hollow shaft 26 drives the fourth transmission shaft 19 to rotate through the large pulley 27, the belt 23, and the small pulley 22, and the fourth transmission shaft 19 drives the fourth transmission shaft 19 through the tenth bevel gear 29, the ninth bevel gear 31, and the fifth transmission shaft 32, the eleventh bevel gear 33 and the twelfth bevel gear 35 drive the sixth transmission shaft 34 to rotate, and the sixth transmission shaft 34 drives the pipeline baffle 17 to flip upward through the spur gear 36, the transmission gear 15 and the baffle shaft 16, so that the oil flows into the spare oil channel 200, and then restarts the circulation through the auxiliary oil pump 25; when the pipeline baffle 17 rotates to the extreme position, the pipeline baffle 17 can no longer rotate, so that the large pulley 27 stops rotating, and then the hollow shaft 26 stops rotating, and the pawl 72 overcomes the elastic force of the ratchet spring 73 and starts to rotate, so that the pawl 72 slips and separates from the tooth surface 65, and makes a sound at the same time, reminding personnel to check the lubrication system, while the second transmission shaft 28 can continue to rotate.

[0030] The beneficial effects of the present invention are as follows: the present invention has a simple structure, is easy to maintain and is easy to use. The present invention can pump the lubricating oil in the engine. At the same time, when the main pump is stuck or blocked, the built-in sensing device can quickly sense the change in oil pressure, and then quickly start the backup pipeline, so that the lubrication system of the engine will not stop pumping oil due to the failure of the main pump, thereby greatly improving the working stability of the engine lubrication system. At the same time, when the main pump stops working, the built-in ratchet structure can also make a sound, thereby reminding the staff to check and eliminate the fault in time.
