Description

Technical Field

[0001] The utility model relates to the technical field of pot bearings, in particular to a high-damping shock-absorbing rubber pot bearing. Background Technique

[0002] The pot rubber bearing is a new type of bridge bearing composed of steel components and rubber. Compared with other types of pot bearings and cast steel roller bearings of the same kind, it has the advantages of large bearing capacity, large horizontal displacement, and flexible rotation. The pot rubber bearing is composed of an upper seat plate, a sealing ring, a rubber plate, a bottom pot, anchor bolts, a dust cover, etc.

[0003] In the Chinese patent with the publication number CN214194099U, a friction-type high-damping rubber bridge shock-absorbing bearing is disclosed. By setting an installation base and bolts, the device can be fixed to the ground pier. By setting high-strength shock-absorbing springs, a shock-absorbing top seat and a shock-absorbing base, the elasticity of the high-strength shock-absorbing springs can be used to reduce the impact caused by bridge vibration. By setting high-damping rubber blocks, an annular side plate and an annular limit block, the elasticity of the high-damping rubber blocks themselves and the resistance of the high-damping rubber blocks to be compressed and extruded and rubbed against the annular side plate can be used to further slow down the vibration of the bridge, achieving the purpose of protecting the bridge itself.

[0004] Although the above scheme uses the cooperation of a limit support rod, a limit sleeve, a limit block and an annular groove to buffer the longitudinal seismic force, these structures will also limit the lateral buffering of the rubber bearing, making the lateral buffering performance of the rubber bearing weaker and not conducive to the protection of the bridge by the rubber bearing. Therefore, we provide a high-damping shock-absorbing rubber pot bearing to solve the above problems. Content of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 - 3 shown, the present invention provides a technical solution: a high-damping shock-absorbing rubber pot bearing, including two connecting steel plates 1, a rubber buffer assembly and a mechanical buffer assembly.

[0026] A bearing plate 3 and a connecting seat 4 are respectively fixedly connected to the two connecting steel plates 1. A cavity 5 is formed in the connecting seat 4. Mounting holes 2 are formed in both of the two connecting steel plates 1. The connecting steel plates 1 are installed on a bridge or a pier through the mounting holes 2. Both the bearing plate 3 and the connecting seat 4 are made of stainless steel.

[0027] The rubber buffer assembly is arranged between the bearing plate 3 and the connecting seat 4 and is used for mainly buffering the force between the two connecting steel plates 1. The rubber buffer assembly includes a rubber pad 6 installed in the cavity 5. A linking block 7 is placed on the rubber pad 6. A mounting groove 8 is formed in the linking block 7. A Teflon plate 9 is installed in the mounting groove 8, and the upper surface of the Teflon plate 9 abuts against the bearing plate 3.

[0028] The transverse impact force will cause the bearing plate 3 and the Teflon plate 9 to slide relatively, thereby buffering the transverse impact force. The longitudinal impact force will cause the linking block 7 to squeeze the rubber pad 6, and buffer the longitudinal impact force through the rubber pad 6.

[0029] The mechanical buffer assembly is arranged inside the rubber buffer assembly to enhance the buffering performance of the rubber buffer assembly. The mechanical buffer assembly includes a connecting rod 10 fixedly connected to the bearing plate 3 and a cylinder 12 fixedly connected inside the cavity 5. A frustum block 11 is fixedly connected to the bottom end of the connecting rod 10. Horizontally push-pull rods 13 arranged in a circumferential array are slidably connected to the cylinder 12. A roller 16 is installed at one end of the horizontally push-pull rod 13 close to the frustum block 11, and the roller 16 abuts against the frustum block 11. A limiting block 14 is fixedly connected to the end of the horizontally push-pull rod 13 away from the roller 16. A first spring 15 is sleeved on the horizontally push-pull rod 13, and the two ends of the first spring 15 are respectively fixedly connected to the cylinder 12 and the limiting block 14.

[0030] The tetrafluoroethylene plate 9, the rubber pad 6, and the linkage block 7 are all annular structures, which are convenient for storing the space for installing the mechanical buffer assembly. When the bearing plate 3 moves horizontally due to a horizontal impact force, the frustum block 11 will drive the horizontally push-pull rod 13 to move horizontally through the roller 16, and buffer the horizontal impact force through the first spring 15.

[0031] A vertical rod 17 is slidably connected to the bottom surface of the frustum block 11. A ball 20 is embedded in the bottom surface of the vertical rod 17. A limiting plate 18 is fixedly connected to the upper surface of the vertical rod 17, and the limiting plate 18 is located inside the frustum block 11. A second spring 19 is sleeved on the vertical rod 17, and the two ends of the second spring 19 are respectively fixedly connected to the limiting plate 18 and the frustum block 11.

[0032] When the horizontally push-pull rod 13 bears a longitudinal impact force, it will cause the bearing plate 3 to drive the frustum block 11 to move up and down on the vertical rod 17 through the connecting rod 10, and under the action of the second spring 19, complete the buffering of the longitudinal impact force.
