[0038] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0039] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0040] The following combines the attached Figures 1 to 14 , and through specific embodiments and their application scenarios, the aluminum alloy bridge support provided by the embodiments of this application will be described in detail.

[0041] Please refer to Figures 1 to 3, some embodiments of the present application disclose an aluminum alloy bridge bearing. Exemplarily, the aluminum alloy bridge bearing includes a first bearing 100, a second bearing 200, a spherical crown liner 300, a pot-shaped liner 400, a first support member 500, and a second support member 600. Among them, the first bearing 100 and the second bearing 200 are basic structural members that can provide an installation basis for other components. Exemplarily, one of the first bearing 100 and the second bearing 200 is used to connect to the bridge pier, and the other is used to connect to the bridge.

[0042] Referring to Figure 1 and Figure 2 , the first bearing 100 and the second bearing 200 are relatively arranged and spaced apart. The spherical crown liner 300 and the pot-shaped liner 400 are disposed between the first bearing 100 and the second bearing 200, and the first bearing 100 and the second bearing 200 are directly or indirectly movably connected through the spherical crown liner 300 and the pot-shaped liner 400, so that relative movement can be achieved between the bridge and the bridge pier within a safe range, improving the safety of the overall bridge structure.

[0043] In some embodiments, referring to Figure 13 , the spherical crown liner 300 has a first flat surface 310 and a first spherical convex surface 320 arranged back to back. The first spherical convex surface 320 is a spherical convex surface. Referring to Figure 9 and Figure 11 , the pot-shaped liner 400 has a second flat surface 410 and a first spherical concave surface 420 arranged back to back. The first spherical concave surface 420 is a spherical concave surface.

[0044] The spherical crown liner 300 is in sliding fit with the first bearing 100 through the first flat surface 310. The pot-shaped liner 400 is in sliding fit with the second bearing 200 through the second flat surface 410, and the first spherical convex surface 320 is in sliding fit with the first spherical concave surface 420.

[0045] Referring to Figure 2 , one end of the first support member 500 is connected to the first bearing 100, and the other end is connected to the pot-shaped liner 400 and generates an elastic force to overcome the approach of the first bearing 100 and the pot-shaped liner 400. Referring to Figure 3 , one end of the second support member 600 is connected to the second bearing 200, and the other end is connected to the spherical crown liner 300 and generates an elastic force to overcome the approach of the second bearing 200 and the spherical crown liner 300.

[0046] In some alternative embodiments, such as Figures 4 to 7As shown, both the first support member 500 and the second support member 600 are elastic structural members, and through their own elastic deformation, an elastic force can be generated between the first support 100 and the second support 200 to overcome the mutual approach of the first support 100 and the second support 200. Therefore, the gravity of the bridge acting on the aluminum alloy bridge support can be at least partially transmitted to the pier through the first support member 500 and the second support member 600, thereby reducing the normal pressure between the moving contact surfaces in the aluminum alloy bridge support, further reducing the frictional resistance to the relative movement of the first support 100 and the second support 200, and further benefiting the reduction of wear on the moving contact surfaces in the bridge support.

[0047] Exemplarily, the moving contact surfaces in the aluminum alloy bridge support can be: the first plane 310, the first spherical convex surface 320, the second plane 410, and / or the first spherical concave surface 420.

[0048] The first support 100 is connected to the second support 200 through the first support member 500 and the pot-shaped liner 400, which can not only make the gravity of the bridge received by the aluminum alloy bridge support at least partially avoid the moving contact surfaces of the spherical crown liner 300 and the pot-shaped liner 400, but also prevent relative sliding between the first support member 500 and other components, thereby benefiting the protection of the first support member 500. Similarly, the second support 200 is connected to the first support 100 through the second support member 600 and the spherical crown liner 300, which can not only make the gravity of the bridge received by the aluminum alloy bridge support at least partially avoid the moving contact surfaces of the spherical crown liner 300 and the pot-shaped liner 400, but also prevent relative sliding between the second support member 600 and other components, thereby benefiting the protection of the second support member 600. Therefore, the aluminum alloy bridge support provided in the above embodiments can reduce the frictional force of each moving contact surface in the aluminum alloy bridge support without increasing the number of moving contact surfaces, thereby benefiting the protection of each moving contact surface in the bridge support. In addition, the elastic force generated by the first support member 500 and the second support member 600 is also beneficial for the bridge to quickly return to its initial position after being stressed, and can also absorb instantaneous large loads and improve the anti-vibration ability of the bridge.

[0049] Refer to Figure 2 and Figure 3 In some embodiments, the aluminum alloy bridge support further includes a sealing ring 1400. Exemplarily, the sealing ring 1400 is disposed between the spherical crown liner 300 and the pot-shaped liner 400, and the sealing ring 1400 is in sealing cooperation with the spherical crown liner 300 and the pot-shaped liner 400 respectively to prevent external liquid or dust particles from entering the moving contact surface between the spherical crown liner 300 and the pot-shaped liner 400, so as to achieve the purpose of protecting the spherical crown liner 300 and the pot-shaped liner 400.

[0050] Refer to Figure 2 and Figure 3, in some embodiments, the aluminum alloy bridge bearing further includes two first support members 500 and two second support members 600. The two first support members 500 are disposed on opposite sides of the spherical crown liner 300, and the two first support members 500 are distributed along a first direction with respect to the spherical crown liner 300. The two second support members 600 are disposed on opposite sides of the spherical crown liner 300, and the two second support members 600 are distributed along a second direction with respect to the spherical crown liner 300, and the first direction is perpendicular to the second direction. Exemplarily, the first direction may be Figure 2 or Figure 9 the direction indicated by the x-axis in Figure 3 or Figure 9 the direction indicated by the y-axis in. In this embodiment, it is beneficial to the force balance of the aluminum alloy bridge bearing in all directions.

[0051] In some embodiments, as Figures 4 to 7 shown, the first support member 500 is fixedly connected to the first bearing 100 and the pot-shaped liner 400 respectively, so as to prevent the first support member 500 from moving relative to the first bearing 100 and the pot-shaped liner 400 from moving relative to each other, and to avoid wear or scratching during the relative movement. Therefore, this solution is beneficial to protecting the first support member 500 and the first bearing 100 and the pot-shaped liner 400 assembled with the first support member 500.

[0052] In some embodiments, as Figures 4 to 7 shown, the second support member 600 is fixedly connected to the second bearing 200 and the spherical crown liner 300 respectively, so as to prevent the second support member 600 from moving relative to the second bearing 200 and the spherical crown liner 300 from moving relative to each other, and to avoid wear or scratching during the relative movement. Therefore, this solution is beneficial to protecting the second support member 600 and the second bearing 200 and the spherical crown liner 300 assembled with the second support member 600.

It should be noted that both 6061 aluminum alloy and 6A02 aluminum alloy are known alloy materials. In some alternative embodiments, the spherical crown liner 300 can be 6061 aluminum alloy prepared and / or processed by selective laser melting technology.

[0058] Preparing some structural members of the bridge support by aluminum alloy material is beneficial to improving the corrosion resistance of the bridge structural members, and is also beneficial to reducing the weight of the bridge support, so as to facilitate the rapid assembly and disassembly of the temporary bridge support.

[0059] In some alternative embodiments, as Figure 10 shown, the spherical crown liner 300 includes a spherical crown body 330 and an anti-corrosion layer 340 provided on the spherical surface of the spherical crown body 330, wherein the spherical crown body 330 is made of 6A02 aluminum alloy and the anti-corrosion layer 340 is made of 6061 aluminum alloy material. This embodiment is beneficial to improving the corrosion resistance of the bridge support.

[0060] Referring to Figure 2 、 Figure 3 and Figure 9 In some embodiments, the aluminum alloy bridge bearing further includes a plurality of sliding plates 700. Sliding plates 700 are provided between the first bearing 100 and the spherical crown liner 300, between the spherical crown liner 300 and the pot-shaped liner 400, and between the pot-shaped liner 400 and the second bearing 200.

[0062] In the above embodiments, by providing the sliding plates 700 between the first bearing 100 and the spherical crown liner 300, between the spherical crown liner 300 and the pot-shaped liner 400, and between the pot-shaped liner 400 and the second bearing 200, it is beneficial to reduce the friction coefficient of each moving contact surface, and thus beneficial to reducing the frictional resistance to slow down the wear between structural members.

[0063] Referring to Figure 13 In some alternative embodiments, both the spherical crown liner 300 and the pot-shaped liner 400 are provided with lubrication channels 350 and lubrication ports 360. The lubrication ports 360 are located on the first plane 310, the second plane 410, the first spherical convex surface 320 and / or the first spherical concave surface 420, and the lubrication channels 350 communicate with the lubrication ports 360. In this embodiment, lubricant can be injected into the first plane 310, the second plane 410, the first spherical convex surface 320 and / or the first spherical concave surface 420 through the lubrication channels 350 to reduce the friction coefficient of the first plane 310, the first plane 310, the first spherical convex surface 320 and / or the first spherical concave surface 420, and thus beneficial to protecting the first plane 310, the first plane 310, the first spherical convex surface 320 and / or the first spherical concave surface 420.

[0064] In some embodiments, there are a plurality of lubrication ports 360, and the plurality of lubrication ports 360 are evenly distributed on the first plane 310, the first plane 310, the first spherical convex surface 320 and / or the first spherical concave surface 420.

With the relative movement between the components, the part in contact with the lubricant continuously rubs against other parts, so that the lubricant can reach each area of the first plane 310, the second plane 410, the first spherical convex surface 320 or the first spherical concave surface 420.

Exemplarily, the elastic member 1000 can be but is not limited to a spring. It should be noted that by selecting a suitable spring specification, the lubricant can be maintained within a certain pressure range to push the lubricant into the lubrication channel 350 and keep the lubrication port 360 always filled with the lubricant.

[0067] Exemplarily, the lubricant can be but is not limited to one or more of molybdenum disulfide, polyurethane, and silicone-based grease.

[0073] Reference Figure 5 、 Figure 6 and Figure 8 In some embodiments, the first baffle 110 and the second baffle 210 at least partially overlap on both sides in the first direction and both sides in the second direction, so that the first baffle 110 and the second baffle 210 can block the dust or water droplets splashing from the external environment from entering the bridge bearing, which is beneficial to keeping the inside of the bridge bearing clean.

[0074] Reference Figure 2 and Figure 3 In some embodiments, the aluminum alloy bridge bearing further includes a connecting component 1300. One end of the connecting component 1300 is connected to the spherical crown liner 300, and the other end is movably connected to the pot-shaped liner 400. And the connecting component 1300 is in limit fit with the spherical crown liner 300 and restricts the pot-shaped liner 400 from moving away from the spherical crown liner 300. In the above embodiments, the connecting component 1300 can provide tension for the spherical crown liner 300 and the pot-shaped liner 400 to ensure the reliability of the aluminum alloy bridge bearing.

[0075] In some embodiments, the connecting component 1300 includes a connecting shaft 1310 and a limit stop 1320. On the side of the pot-shaped liner 400 facing away from the first spherical concave surface 420, there is a receiving groove 430. The bottom of the receiving groove 430 is a second spherical convex surface 431 concentric with the first spherical concave surface 420. The limit stop 1320 is arranged in the receiving groove 430 and the limit stop 1320 does not protrude from the second plane 410. The side of the limit stop 1320 adjacent to the second spherical convex surface 431 is a second spherical concave surface 1321 that is in sliding fit with the second spherical convex surface 431. One end of the connecting shaft 1310 is connected to the limit stop 1320, and the other end is connected to the spherical crown liner 300.

[0076] Exemplarily, the second spherical concave surface 1321 is a spherical concave surface. The second spherical convex surface 431 is a spherical convex surface.

[0077] In the above embodiments, the connecting component 1300 can be used to provide the aluminum alloy bridge bearing with the pulling force that the bridge receives in the vertical direction, thereby improving the reliability of the bridge.
