Description

Technical Field

[0001] The utility model relates to the technical field of pot-type rubber bearings, in particular to a seismic-resistant pot-type rubber bearing. Background Art

[0002] Pot-type rubber bearing is a kind of bridge bearing, which is mainly used to connect the superstructure and substructure of the bridge so that it can bear and transmit traffic loads and adapt to the deformation and rotation of the bridge structure. Due to its unique design, the pot-type rubber bearing has many performance advantages. It has a low friction coefficient, excellent load-bearing capacity and good buffering performance, which makes it widely used in bridge engineering.

[0003] A Chinese patent with announcement number CN216551543U discloses a seismic-resistant bridge basin-type rubber bearing, which, through the provision of auxiliary components, can achieve a circulation flow of lubricating oil through an airbag during the vibration of the bearing, thereby achieving a good lubrication effect on the contact points inside the bearing and reducing excessive wear of the bearing due to relative sliding.

[0004] Although the device can reduce friction by spraying lubricating oil on the contact surface of the PVC slide plate and the stainless steel plate through the airbag, the upper seat plate needs to withstand the vibration of the bridge after being connected to the bridge, and the stainless steel plate can only move longitudinally after being matched with the lower seat plate. It is not only difficult to buffer the vibration force transmitted from different directions by the bridge, but also it is difficult to achieve a good earthquake resistance effect by relying solely on the combination of the PVC slide plate and the rubber plate. To this end, we provide a seismic pot-type rubber bearing to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a seismic-resistant pot-type rubber bearing.

[0007] 2) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-seismic basin-type rubber bearing, comprising a lower seat plate and an upper seat plate, the lower seat plate is fixedly connected with a basin body, a rubber block is arranged on the basin body, a mounting groove is opened on the rubber block, a sealing ring is installed in the mounting groove, a stainless steel plate is placed on the upper surface of the rubber block, a placement groove is opened on the stainless steel plate, a polytetrafluoroethylene plate is placed in the placement groove, a guide block is fixedly connected to the polytetrafluoroethylene plate, a fixed steel plate is fixedly connected to the upper seat plate, a movable groove is opened on the bottom surface of the fixed steel plate, the top end of the guide block is slidably connected in the movable groove, and a support component in a circular array is arranged on the lower seat plate.

[0009] Furthermore, a positioning groove is formed on the bottom surface of the stainless steel plate, and a positioning block is fixedly connected to the upper surface of the rubber block, and the positioning block is inserted into the positioning groove.

[0010] Furthermore, a dust cover is fixedly connected to the bottom surface of the fixed steel plate, and the bottom end of the dust cover abuts against the basin body.

[0014] 3) Beneficial effects:

[0015] Compared with the prior art, the seismic-resistant pot-type rubber bearing has the following beneficial effects:

[0016] The utility model uses the coordinated design of rubber blocks, stainless steel plates and positioning blocks to enable the bearings to effectively absorb vibration energy from different directions. When the bridge is subjected to an earthquake or other dynamic loads, the inclination of the stainless steel plates will squeeze the rubber blocks. The elastic deformation of the rubber blocks will further buffer the impact force, significantly improving the absorption capacity of multi-directional vibrations and enhancing the seismic resistance of the bridge. The utility model also provides additional vertical support for the bearings by arranging support components. When the bridge tilts, the hemispherical blocks act on the sliders through the support rods to compress the springs, which not only effectively disperses the pressure from the superstructure, but also uses the rebound characteristics of the springs to increase the restoring force of the bearings, further improving the overall seismic resistance effect, while also protecting the bearings from damage by abnormal stress, ensuring stability and reliability in long-term use.
