[0001] This utility model relates to the field of spherical bearing technology, and specifically to a spherical bearing that is easy to assemble. Background Technology

[0002] Spherical bearings play a variety of important roles in the fields of architecture and bridge construction. They can withstand vertical and rotational loads, enabling structures to smoothly withstand external forces.

[0003] Spherical bearings have a lower support plate. During the production of spherical bearings, the lower support plate is relatively thick, and its processing time is usually long, thus affecting the production efficiency of the spherical bearings. Therefore, there is an urgent need to design a spherical bearing that is easy to assemble to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a spherical support that is easy to assemble, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A spherical support that is easy to assemble includes an upper support plate, a lower support plate at the bottom of the upper support plate, a base plate, a support plate at the top of the base plate, an upper insertion hole on the bottom outer wall of the support plate, a positioning tenon inserted into the upper insertion hole, a lower insertion hole on the top outer wall of the base plate, the positioning tenon inserted into the lower insertion hole, a vent groove on one side of the outer wall of the positioning tenon, and tapered surfaces at both ends of the positioning tenon.

[0007] Furthermore, a spherical crown plate is provided between the support plate and the upper support plate. The bottom of the spherical crown plate is arc-shaped. The top outer wall of the support plate is adapted to the spherical crown plate. A limiting ring is fixed to the bottom outer wall of the upper support plate. The limiting ring is located outside the support plate.

[0008] Furthermore, a friction plate is fixed to the top outer wall of the crown plate, and a stainless steel plate is fixed to the bottom outer wall of the upper support plate.

[0009] Furthermore, the stainless steel plate has evenly distributed through holes on its top outer wall, the spherical crown plate has an installation groove on its top outer wall, a sealing ring is fixed inside the installation groove, and a raised strip is integrally formed on the top outer wall of the sealing ring.

[0010] Furthermore, sleeves are fixed at the four bottom corners of the lower support plate, and anchor bolts are fixed inside the sleeves.

[0011] Furthermore, a step is provided in the middle of the positioning tenon, and the step is located at the top of the base plate.

[0012] In the above technical solution, the spherical bearing provided by this utility model, which is easy to assemble, has the following advantages: By dividing the lower support plate into a base plate and a support plate, and limiting the base plate and support plate by a positioning tenon, the base plate and support plate can be processed simultaneously during the processing of the lower support plate, shortening the processing time and thus improving the efficiency of the production of the lower support plate of the spherical bearing. At the same time, the large components are disassembled into smaller parts, which also facilitates the assembly of the bearing. By opening a ventilation groove on the outer wall of the positioning tenon, when the positioning tenon is inserted into the lower insertion hole and the upper insertion hole, the lower insertion... Air inside the joint and upper insertion joint can flow out through the vent groove, thus preventing air from hindering the insertion of the positioning tenon. At the same time, the conical surface guides the installation of the positioning tenon, making the assembly between the base plate and the support plate easier. The through hole increases the friction between the friction plate and the stainless steel plate, resulting in better friction energy dissipation when the support enters the seismic isolation condition. The raised strip on the sealing ring improves the sealing effect between the spherical crown plate and the upper support plate, preventing dust from entering the friction plate and the stainless steel plate and affecting the friction effect.

[0022] Specifically, in this embodiment, an upper support plate 1 is included, and a lower support plate 2 is provided at the bottom of the upper support plate 1. The lower support plate 2 includes a base plate 5, and a support plate 4 is provided at the top of the base plate 5. The upper surface of the support plate 4 has a concave arc-shaped surface. An upper insertion hole 8 is opened on the bottom outer wall of the support plate 4, and a positioning tenon 10 is inserted into the upper insertion hole 8. A lower insertion hole 9 is provided on the top outer wall of the base plate 5, and the positioning tenon 10 is inserted into the lower insertion hole 9. A ventilation groove 17 is provided on one side of the outer wall of the positioning tenon 10. By opening a ventilation groove 17 on the outer wall of the positioning tenon 10, when the positioning tenon 10 is inserted into the lower insertion hole 9 and the upper insertion hole 8, the positioning tenon 10 and the upper insertion hole 8 are properly positioned. Both the lower insertion hole 9 and the upper insertion hole 8 are transition fits. The air inside the lower insertion hole 9 and the upper insertion hole 8 can flow out through the vent groove 17, so that the air will not create resistance to the insertion of the positioning tenon 10. Both ends of the positioning tenon 10 are provided with tapered surfaces 18. At the same time, the tapered surfaces 18 provide a guiding function for the installation of the positioning tenon 10, making the assembly between the base plate 5 and the support plate 4 easier. The middle of the positioning tenon 10 is provided with a step 19. The step 19 is located at the top of the base plate 5 and serves as a mark. The step 19 makes it easy to see whether the upper and lower parts of the positioning tenon 10 are fully inserted into the lower insertion hole 9 and the upper insertion hole 8.

[0023] This utility model provides a spherical support that is easy to assemble. By dividing the lower support plate 2 into two parts, a base plate 5 and a support plate 4, and using a positioning tenon 10 to limit the position of the base plate 5 and the support plate 4, the two parts, the base plate 5 and the support plate 4, can be processed simultaneously during the processing of the lower support plate 2, which shortens the processing time and improves the efficiency of the production of the lower support plate 2 of the spherical support. At the same time, the large parts are disassembled into smaller parts, which also facilitates the assembly of the support.

[0024] In another embodiment of this utility model, a spherical crown plate 20 is provided between the support plate 4 and the upper support plate 1.

The top outer wall of the stainless steel plate 14 is provided with... The spherical crown plate 20 has uniformly distributed through holes 16. The top outer wall of the spherical crown plate 20 has an installation groove 11. A sealing ring 12 is fixed inside the installation groove 11. The top outer wall of the sealing ring 12 has an integrally formed protrusion 15. The sealing ring 12 is located on the outside of the friction plate 13. Through the through holes 16, the friction between the friction plate 13 and the stainless steel plate 14 is increased, thereby improving the friction energy dissipation effect when the support enters the seismic isolation condition. Through the protrusion 15 on the sealing ring, the sealing effect between the spherical crown plate 20 and the upper support plate 1 is improved, preventing dust from entering the friction between the friction plate 13 and the stainless steel plate 14 and affecting the friction effect. Sleeves 6 are fixed at the bottom four corners of the lower support plate 2. Anchor bolts 7 are fixed inside the sleeves 6. Anchor bolts 7 are also fixed at the top four corners of the upper support plate 1. The support is fixed to the upper and lower parts of the bridge through the anchor bolts 7.

[0025] Working principle: When using the support plate 4 and the base plate 5, first insert the positioning tenon 10 into the lower insertion hole 9 of the base plate 5, and make the step 19 close to the base plate 5. Then insert the positioning tenon 10 into the upper insertion hole 8 of the support plate 4, so that the support plate 4 can be positioned on the base plate 5.
