Description

Technical Field

[0001] This utility model relates to the field of building equipment, and in particular to a bridge support protective cover that is easy to maintain. Background Technology

[0002] Bridge bearings are important structural components connecting the superstructure and substructure of a bridge. They reliably transfer the reaction forces and deformations (displacement and rotation) of the superstructure to the substructure, thus ensuring that the actual stress condition of the structure matches the calculated theoretical diagram. In seismic zones, seismic resistance measures should be considered. There are many types of existing bridge bearings, mainly including: circular rubber bearings, pot bearings, damping rubber bearings, and seismic isolation rubber bearings. Different bearings are used for different regions, but to ensure the long-term use of bridge bearings, protective covers are often designed for protection.

[0003] A search revealed Chinese Patent Publication No. CN212983579U, which discloses a box-type protective cover for bridge bearings. This cover achieves good protection by incorporating support columns, chrome-plated metal semi-rings, and flexible blocks. Two protective shells enclose the central structure of the bridge bearing, with flexible blocks at the top and bottom acting as buffers. Under pressure, the entire protective shell forms a relatively sealed environment, preventing moisture ingress. The chrome-plated metal semi-rings effectively prevent moisture from entering from the sides, while the support columns lift the four corners of the seismic isolation rubber bearing, ensuring structural stability and improving the equipment's performance.

[0004] The aforementioned protective cover has certain drawbacks during use. For example, when the two chrome-plated metal semi-rings are joined, a gap remains in the middle, allowing moisture to easily enter and reducing the protective effect of the cover. Therefore, a bridge bearing protective cover that is easy to maintain is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bridge bearing protective cover that is easy to maintain. It aims to improve the problem in the prior art where there is a gap in the middle when the two chrome-plated metal semi-rings are joined together, which allows moisture to easily enter the cover and reduce its protective effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bridge bearing protective cover that is easy to maintain includes two sets of outer shells. Flexible blocks are fixedly connected to the surface and bottom of the outer shells. The interior of the outer shells is filled with cement filler blocks. A chrome-plated metal semi-ring is fixedly connected to the inner wall of the outer shell. An extension component is provided inside the chrome-plated metal semi-ring. The extension component includes a groove. The groove is formed at the end of the chrome-plated metal semi-ring. An extension plate is slidably connected inside the groove. The extension plate is elastically connected to the inner wall of the groove by a return spring.

[0008] As a further description of the above technical solution:

[0009] The two sets of housings are hinged together on one side by a hinge.

[0010] As a further description of the above technical solution:

[0011] Each of the two sets of housings has a connecting block fixedly connected to the other side. The side wall of the connecting block has a groove, and a U-shaped rod is inserted into the inside of the groove.

[0012] As a further description of the above technical solution:

[0013] A bending plate is fixedly connected to the top of the U-shaped rod.

[0014] As a further description of the above technical solution:

[0015] The surface of the chrome-plated metal semi-ring is provided with a sliding groove, which is connected to the groove, and a limit rod is slidably connected inside the sliding groove.

[0016] As a further description of the above technical solution:

[0017] The inner side of the outer shell is semi-circular, and the outer side is rectangular. When the two outer shells are combined, the inner side forms a complete circle, and the outer side forms a square.

[0018] As a further description of the above technical solution:

[0019] The two sets of chrome-plated metal semi-rings are connected end to end.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the extension plate is provided with elastic support by the return spring, so that the extension plate extends from the end of the chrome-plated metal half ring and fits tightly with the tail end of another set of chrome-plated metal half rings, thereby avoiding gaps between the chrome-plated metal half rings, avoiding structural corrosion caused by oxygen penetration, and improving the service life and safety of the bridge bearing protective cover.

[0022] 2. In this utility model, by lifting the bending plate upwards, the U-shaped rod is pulled out from the inside of the slot. At this time, the connection between the two sets of outer shells is lost. Then, by using the hinge, one set of outer shells can be opened, so that the bridge bearing can be inspected, repaired or replaced. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a bridge bearing protective cover that is easy to maintain. It includes two sets of outer shells 1. Flexible blocks 3 are fixedly connected to the surface and bottom of each outer shell 1, enhancing the adaptability between the protective cover and the bridge bearing. When the external environment changes, the flexible blocks 3 can bend or deform, thereby reducing the impact of vibration or external forces on the bearing. The interior of each outer shell 1 is filled with cement filler blocks 4. The inner side of each outer shell 1 is semi-circular, and the outer side is rectangular. When the two outer shells 1 are combined, the inner side forms a complete circle, and the outer side is a square. The bridge bearing has a columnar structure, and the two circular inner shells 1 better fit the outer wall of the bridge bearing.

[0031] Reference Figure 2 - Figure 3 A chrome-plated metal semi-ring 5 is fixedly connected to the inner wall of the outer casing 1. Two sets of chrome-plated metal semi-rings 5 ​​are connected end to end. The chrome-plated metal semi-rings 5 ​​serve as protection for the outer periphery of the middle part of the bridge support, effectively preventing oxygen penetration and preventing structural corrosion. An extension component 6 is provided inside the chrome-plated metal semi-rings 5. The extension component 6 is used to fill the gap between the two sets of chrome-plated metal semi-rings 5. The extension component 6 includes a groove 61, which is opened at the end of the chrome-plated metal semi-ring 5. An extension plate 62 is slidably connected inside the groove 61. The extension plate 62 is elastically connected to the inner wall of the groove 61 by a return spring 63. The return spring 63 provides elastic support for the extension plate 62, so that the extension plate 62 extends from the end of the chrome-plated metal semi-ring 5 and fits tightly with the tail end of the other set of chrome-plated metal semi-rings 5, thereby avoiding gaps between the chrome-plated metal semi-rings 5.

[0032] Reference Figure 2 - Figure 3 The surface of the chrome-plated metal semi-ring 5 is provided with a groove 64, which is connected to the groove 61. A limit rod 65 is slidably connected inside the groove 64. The groove 64 and the limit rod 65 are used to limit the movement range of the extension plate 62, thereby preventing the extension plate 62 from disengaging from the inside of the groove 61 under the elastic force of the return spring 63.

[0033] Reference Figure 1 - Figure 2 The two sets of outer shells 1 are hinged to each other on one side by hinge 11. The hinge 11 allows the protective cover to be opened, which facilitates the inspection, maintenance or replacement of the bridge bearing. The use of hinge 11 makes the protective cover more flexible and can be opened like a door, providing convenient access space.

[0034] Reference Figure 1 , Figure 4 Each of the two sets of outer shells 1 has a connecting block 2 fixedly connected to its other side. The side wall of the connecting block 2 has a slot 21, and a U-shaped rod 22 is inserted into the slot 21. A bending plate 23 is fixedly connected to the top of the U-shaped rod 22. The combination of the slot 21 and the U-shaped rod 22 provides a reliable connection method, ensuring that the two sets of outer shells 1 can be firmly closed together. The bending plate 23 facilitates the removal of the U-shaped rod 22 from the inside of the slot 21.

[0035] Working principle: When maintenance of the bridge bearing is required, the operator can first lift the bending plate 23 upwards. The bending plate 23 drives the U-shaped rod 22 out of the slot 21, at which point the connection between the two sets of outer shells 1 is lost. Then, one set of outer shells 1 can be opened using the hinge 11 to inspect, repair, or replace the bridge bearing. After maintenance, the outer shell 1 is closed, and the U-shaped rod 22 is inserted into the slot 21 to connect the two sets of outer shells 1 together.

[0036] Due to the extension component 6, the return spring 63 provides elastic support to the extension plate 62, allowing the extension plate 62 to extend from the end of the chrome-plated metal semi-ring 5 and fit tightly against the tail end of another set of chrome-plated metal semi-rings 5. This avoids gaps between the chrome-plated metal semi-rings 5, prevents structural corrosion caused by oxygen penetration, and improves the service life and safety of the bridge bearing protective cover.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
