Description

Technical Field

[0001] This utility model relates to the field of bridge rubber bearing technology, specifically a bridge rubber bearing that is easy to maintain and replace. Background Technology

[0002] Bridge rubber bearings are important structural components connecting the superstructure and substructure of a bridge. Located between the bridge and the bearing pad, they reliably transfer the loads and deformations (displacement and rotation) borne by the superstructure to the substructure, making them an important force transmission device for bridges.

[0003] Bridge rubber bearings require replacement or maintenance after prolonged use. The common method involves using multiple hydraulic jacks to lift the bridge, perform the replacement or maintenance, and then lower the jacks back down. However, most existing bridge rubber bearings consist of two separate parts, upper and lower. Replacement or maintenance often requires disassembling and replacing both parts separately. The most easily damaged or replaceable components of bridge rubber bearings are the rubber parts and the parts that create sliding contact between the upper and lower parts. Disassembling and replacing both parts completely wastes other components and increases maintenance costs. Utility Model Content

[0022] 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.

[0023] Please see Figures 1 to 5A bridge rubber bearing that is easy to maintain and replace includes a bridge superstructure connection assembly and a bridge substructure connection assembly. The bridge superstructure connection assembly includes a top connector 10, a top sliding seat 20, and several bolts 30. The bridge substructure connection assembly includes a bottom sliding seat 40, a rubber seat 50, and a bottom connector 60. When assembling and using the bridge superstructure connection assembly, the top sliding seat 20 is inserted into the center of the top connector 10 through its bottom opening. The outer edge of the top sliding seat 20 is then connected and fixed to the top connector 10 using several bolts 30. Finally, the top connector 10 is connected and fixed to the bridge using locking devices such as bolts. When assembling and using the bridge substructure connection assembly, the bottom sliding seat 40 is embedded in the top of the rubber seat 50. The rubber seat 50 is then inserted into the center of the bottom connector 60 through its top opening. Finally, the bottom connector 60 is connected and fixed using locking devices such as bolts. When the bridge is hoisted onto the pier, the lower end of the top sliding seat 20 can extend into the inner cavity of the bottom sliding seat 40 and contact its bottom inner wall. By utilizing the movable contact between the top sliding seat 20 and the bottom sliding seat 40, as well as the elastic deformation of the rubber seat 50, the bridge rubber bearing can adapt to the rotation and horizontal displacement of the beam end, and the bridge rubber bearing can effectively transfer the load of the bridge to the pier.

[0024] See Figure 2 and Figure 4 The top connector 10 includes a top plate 11, a top protective cover 12, a star-shaped positioning bracket 13, and a plurality of threaded seats 14. Multiple connecting holes are formed around the periphery of the top plate 11, allowing locking elements to pass through and be fixedly connected to the bridge. The lower end of the top protective cover 12 has an opening, and its upper end is fixedly connected to the top plate 11. The star-shaped positioning bracket 13 is formed in the inner center of the top protective cover 12, and extends from the center in multiple directions to form long arms, the ends of which are fixedly connected to the top protective cover 12. Positioning protrusions 131 are formed on the long arms facing the top sliding seat 20 and are used to define the position of the top sliding seat 20 during assembly. A plurality of threaded seats 14 are formed at intervals on the side of the top plate 11 facing the top protective cover 12 and are used to engage bolts 30 to fix the top sliding seat 20.

[0025] The top sliding seat 20 includes a fixing part 21 and a first contact part 22. The diameter of the first contact part 22 is smaller than the diameter of the fixing part 21, and the first contact part 22 is formed at the bottom center of the fixing part 21. A plurality of notches 211 are formed on the outer edge of the fixing part 21, and the bolt 30 passes through the notches 211 and is threadedly connected to the threaded seat 14. When the top sliding seat 20 is placed, the plurality of positioning protrusions 131 on the star-shaped positioning bracket 13 can limit the position of the fixing part 21.

[0026] See Figure 3 and Figure 5 The upper end of the rubber seat 50 has an opening, allowing the bottom sliding seat 40 to be inserted and secured. Multiple evenly distributed grooves 51 are formed radially along the outer edge of the rubber seat 50, and a positioning part 52 with a diameter smaller than that of the rubber seat 50 is formed at the lower end of the rubber seat 50. Both the grooves 51 and the positioning part 52 are used to assemble with the bottom connector 60.

[0027] The bottom connector 60 includes a base plate 61, an inner positioning ring 62, a bottom protective cover 63, and multiple inserts 64. The inner positioning ring 62 is formed on the side of the base plate 61 facing the rubber seat 50, and the positioning part 52 is inserted into the inner positioning ring 62 and secured. The bottom protective cover 63 is formed on the outer side of the inner positioning ring 62, and multiple inserts 64 are evenly formed along the radial direction of the base plate 61 on the top of the inner wall of the bottom protective cover 63. When the rubber seat 50 is inserted into the bottom connector 60, the rubber seat 50 can be inserted into the bottom protective cover 63 by utilizing the multiple grooves 51 on its outer edge that are adapted to the inserts 64. The inserts 64 have a certain amount of room to move within the corresponding grooves 51.

[0028] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
