[0041] It should also be noted that the lubrication blower mechanism 2 includes an oil reservoir 21 at the top, a rounded block 27 fixedly connected to the bottom of the oil reservoir 21, and round tubes 22 slidably connected to both sides of the bottom of the rounded block 27. The top of the round tubes 22 is connected to the bottom of the oil reservoir 21, and the round tubes 22 are slidably connected to the oil reservoir 21. A second telescopic rod 29 is also fixedly connected to the bottom of the rounded block 27, and a C-shaped frame 24 is fixedly connected to the bottom of the second telescopic rod 29. The bottom of the round tubes 22 is fixedly connected to the C-shaped frame 24.

[0042] Please see Figure 1 , Figure 5 and Figure 6 The oil storage tank 21 at the top of the lubrication blower mechanism 2 is used to store oil. The rounded corner block 27 fixedly connected to the bottom of the oil storage tank 21 provides support for the components fixedly connected to its top and bottom. The round tube 22 sliding at the bottom of the rounded corner block 27 is slidably connected to the oil storage tank 21 and is used to transport the oil stored in the oil storage tank 21. The round tube 22 is fixedly connected to the bottom C-shaped frame 24 and passes through the C-shaped frame 24 to transport the oil to the roller 26. The reinforcing ring 23 is used to reinforce the round tube 22 fixedly connected to the C-shaped frame 24. The second telescopic rod 29 can be used to adjust the height of the roller 26 and can also be used to raise the round tube 22 to stop the oil delivery.

[0043] It should also be noted that the bottom sides of the C-shaped frame 24 are rotatably connected to the No. 4 round rod 25, the outer side of the No. 4 round rod 25 is fixedly connected to the roller 26, and the bottom of the rounded corner block 27 is fixedly connected to the fan 28.

[0044] Please see Figure 1 , Figure 5 and Figure 6 The No. 4 round rod 25, which is rotatably connected to both sides of the bottom of the C-shaped frame 24, is used to rotate the roller 26. The roller 26 is used to evenly coat the oil conveyed in the round tube 22 onto the surface of the guide rail 33. The fan 28, which is fixedly connected to the bottom of the rounded corner block 27, can be used to blow away the metal shavings and dust produced by the grinding disc 13.

[0045] It should also be noted that the support body 31 at the bottom of the support mechanism 3 is fixedly connected to the top of the guide rail 33, and two rectangular grooves 32 are also provided on both sides of the support body 31.

[0046] Please see Figure 1 and Figure 7The bottom of the support mechanism 3 is provided with a second rectangular groove 32 on both sides of the support body 31 for the rollers on the lifting and grinding mechanism 1 to roll, thereby improving the protection and grinding efficiency of the guide rail 33.

[0047] When the guide rail 33 needs to be protected and polished, the support frame 11 at the top of the lifting and polishing mechanism 1 can be aligned with the second rectangular groove 32 on both sides of the bottom support body 31 of the support mechanism 3. The height of the first roller 15 is adjusted by the first telescopic rod 19 so that the first roller 15 contacts the upper and lower surfaces of the second rectangular groove 32, and the second roller 111 contacts one side surface of the second rectangular groove 32. This allows the lifting and polishing mechanism 1 to slide. At this time, the hydraulic device 113 is activated to adjust the polishing disc 13 to a height that can contact the surface of the guide rail 33. The motor 14 is started to drive the polishing disc 13 to rotate through the worm gear 116 and worm wheel 117, thereby polishing the guide rail 33. Since the rounded corner block 27 is installed on one side of the support frame 11, the lubrication blower... Mechanism 2 and lifting and grinding mechanism 1 are fixedly connected. Lubricating oil is placed in oil reservoir 21, and then blower 28 is started. Blower 28 blows away metal shavings from grinding disc 13 and impurities from the guide rail 33 surface. Then, the second telescopic rod 29 is adjusted so that roller 26 can contact the guide rail 33 surface, and the round tube 22 is slidably connected to rounded corner block 27. When the bottom of round tube 22 descends to a certain height, the oil will cover the top of round tube 22, allowing the lubricating oil to be transported to roller 26 through round tube 22. Pushing lifting and grinding mechanism 1 moves lubricating blower mechanism 2. Simultaneously, due to the friction between roller 26 and guide rail 33 surface, roller 26 applies oil to the guide rail 33 surface, protecting it. Support body 31 provides sliding support to support frame 11 on lifting and grinding mechanism 1.
