Description

Technical Field

[0001] This application relates to the field of bolt anti-rust technology, and particularly to an anti-rust structure for the fixing bolts of airport high mast lights. Background Art

[0002] Airport high mast lights are large lighting facilities mainly used to provide lighting for the aircraft parking positions at airports. They usually consist of a steel conical lamp post over 15 meters and a high-power combined lamp holder, with a designed maximum wind resistance of up to 60 m / s. The functionality of high mast lights is mainly based on the frame structure, and there are also designs mainly for decoration. The lamp posts and lamp discs are usually treated by hot-dip galvanizing to enhance weather resistance.

[0003] In the related art, referring to Figure 1 , a flange plate 03 is fixed at the bottom of the high mast light 02. During installation, a foundation 01 is poured at the position corresponding to the installation of the high mast light 02 at the airport, and then the flange plate 03 of the high mast light 02 is fixed on the foundation 01 through fixing bolts 04 and fixing nuts 05 to complete the fixation of the high mast light 02.

[0004] In actual use, it is found that the fixing bolts 04 and fixing nuts 05 used to fix the high mast light 02 on the foundation 01 are exposed to the air for a long time and are corroded by rainwater, which will reduce the service life. Summary of the Invention

[0005] In order to improve the service life of the fixing bolts and fixing nuts of high mast lights, this application provides an anti-rust structure for the fixing bolts of airport high mast lights.

[0006] The anti-rust structure for the fixing bolts of airport high mast lights provided by this application adopts the following technical solution:

[0007] An anti-rust structure for the fixing bolts of airport high mast lights includes a sleeve, a plug, and an anti-rust layer applied on the outer sides of the fixing bolts and fixing nuts. The sleeve is coaxially sleeved on the outer side of the fixing bolt, and the plug is fixed at the top of the sleeve.

[0008] By adopting the above technical solution, applying an anti-rust layer on the outer sides of the fixing bolts and fixing nuts can effectively isolate the fixing bolts and fixing nuts from the water vapor in the air, thereby preventing the fixing bolts and fixing nuts from rusting; sleeving a fixing sleeve on the outer sides of the fixing bolts and fixing nuts and blocking it with a plug can protect the fixing bolts, fixing nuts, and the anti-rust layer, reduce the entry of rainwater, and thus extend the service life.

[0009] Optionally, the sleeve is filled with an anti-rust filler.

[0010] By adopting the above technical solution, filling the anti-rust filler inside the sleeve can further improve the anti-rust level of the fixing bolt and the fixing nut, and at the same time can also improve the connection strength between the sleeve and the fixing bolt.

[0011] Optionally, the inner diameter of the sleeve is 1 - 1.5 cm larger than the outer diameter of the fixing nut, and the sleeve is 1.5 - 3 cm higher than the fixing bolt.

[0012] By adopting the above technical solution, through actual application, it is found that after setting the sleeve to the above dimensions, the anti-rust filler can fully wrap the fixing bolt and the fixing nut, improving the overall anti-rust and anti-corrosion capabilities.

[0013] Optionally, a waterproof mortar layer is poured on the flange at the peripheral side of the lower end of the sleeve.

[0014] By adopting the above technical solution, when applied to some harsh environments, pouring a waterproof mortar layer at the lower end of the sleeve can effectively improve the installation stability of the sleeve, and at the same time reduce the penetration of rainwater from the lower end of the sleeve into the interior.

[0015] Optionally, the sleeve is set as a transparent tube body.

[0016] By adopting the above technical solution, setting the sleeve as a transparent tube can facilitate the staff to observe the internal situation in a timely manner.

[0017] Optionally, both the anti-rust layer and the anti-rust filler are set as grease.

[0018] By adopting the above technical solution, grease also has good anti-rust ability, and at the same time, grease has high viscosity, which can improve the connection strength between the sleeve and the fixing bolt.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. By applying an anti-rust layer on the outer sides of the fixing bolt and the fixing nut, it can effectively isolate the fixing bolt and the fixing nut from contacting the water vapor in the air, thereby preventing the fixing bolt and the fixing nut from rusting. By sleeving a fixing sleeve on the outer sides of the fixing bolt and the fixing nut and plugging it with a plug, the fixing bolt, the fixing nut, and the anti-rust layer can be protected, reducing the entry of rainwater, thereby extending the service life;

[0021] 2. By filling the anti-rust filler inside the sleeve, the anti-rust level of the fixing bolt and the fixing nut can be further improved, and at the same time, the connection strength between the sleeve and the fixing bolt can also be improved;

[0022] 3. When applied to some harsh environments, by pouring a waterproof mortar layer at the lower end of the sleeve, the installation stability of the sleeve can be effectively improved, and at the same time, the penetration of rainwater from the lower end of the sleeve into the interior can be reduced.

[0028] Embodiment 1:

[0029] Embodiment 1 of the present application discloses an anti-rust structure for the fixing bolt 04 of an airport high mast light 02. Referring to Figure 2 and Figure 3 , it includes a sleeve 1 and a plug 2. The sleeve 1 is made of a transparent cylindrical tube. The inner diameter of the sleeve 1 is 1 - 1.5 cm larger than the outer diameter of the fixing nut 05, and the height of the sleeve 1 is 1.5 - 3 cm higher than the height of the fixing bolt 04. The sleeve 1 is sleeved outside the fixing bolt 04; the plug 2 is a lid for sleeving and sealing the sleeve 1, and the plug 2 is sleeved and fixed at the upper end of the sleeve 1.

[0030] During construction, a layer of grease is first applied as the rust prevention layer 3 on the outside of the fixing bolt 04 and the fixing nut 05 to ensure that the fixing bolt 04 and the fixing nut 05 are completely wrapped by the grease, reducing the probability of rusting. Then, the sleeve 1 is sleeved outside the fixing bolt 04 and the fixing nut 05, and the sleeve 1 is filled with a rust prevention filler 4. The rust prevention filler 4 is set as grease, so that the fixing bolt 04 and the fixing nut 05 are immersed in the grease, further reducing the probability of rusting of the fixing bolt 04 and the fixing nut 05. Finally, the plug 2 is covered on the upper end of the sleeve 1.

[0031] The implementation principle of the anti-rust structure of the fixing bolt 04 of the high mast light 02 disclosed in Embodiment 1 of the present application is as follows: By using grease to wrap the fixing bolt 04 and the fixing nut 05, the contact between the fixing bolt 04, the fixing nut 05 and external moisture is isolated, thereby effectively preventing the fixing bolt 04 and the fixing nut 05 from rusting; Then, the grease is protected by the sleeve 1 and the plug 2 to reduce the influence of the external environment on the grease; At the same time, after a period of time, the grease, the fixing bolt 04 and the fixing nut 05 can be detected by opening the plug 2, which can effectively improve the service life.

[0032] Embodiment 2:

[0033] The difference between Embodiment 2 and Embodiment 1 of the present application is that, with reference to Figure 4 , a waterproof mortar layer 5 with a height of 5 cm is poured on the flange at the bottom of the high mast light 02, and the bottom of the sleeve 1 is wrapped by the waterproof mortar layer 5. In a harsh environment, the waterproof mortar layer 5 can improve the connection strength between the sleeve 1 and the flange 03 and prevent the sleeve 1 from tipping over; At the same time, it can effectively reduce the penetration of rainwater from the bottom of the sleeve 1 into the interior, thereby effectively improving the overall service life.

[0034] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
