As a key component connecting bridge superstructure and substructure, bridge bearing bears the important functions of transmitting superstructure load and adapting to bridge deformation. However, over time, these bridge bearings are prone to positional deviation under the long-term continuous stress state.

Under the combined action of these factors, the stable state of the bridge bearing is gradually broken. Once the bridge bearing deviates, its stability will be significantly insufficient. This not only makes the bearing unable to effectively perform its intended function, leading to uneven load transmission of the superstructure, but also can further cause local stress concentration in the bridge structure, accelerate the damage of the bridge structure, reduce the service life of the bridge, and even pose a serious threat to the overall safety of the bridge.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0025] Referring to Figure 1 Figure 5 An embodiment provided by the utility model: a bridge support with a stable mechanism, comprising four stable mechanisms 1, a lower support 2 and an upper support 3. The stable mechanism 1 comprises a rocker 107 and a guide column 102. The rocker 107 is fixedly provided with a rocker 112 on both sides of the rear end. The two rockers 112 are hingedly provided with a positioning column 113 through a hinged column 111. The guide column 102 is fixedly provided with a side pressure plate 101 at the rear end.
[0026] The rocker 107 is movably sleeved with an insertion column 114 at the center. The insertion column 114 is fixedly provided with a retaining ring 105 at the upper end. The retaining ring 105 is fixedly provided with a support column 104 at the upper end. The support column 104 is fixedly provided with a buffer damper 103 at the upper end. The insertion column 114 is fixedly provided with a No. 2 magnetic ring 109 at the lower end. The No. 2 magnetic ring 109 is fixedly provided with a base 110 at the lower end. The insertion column 114 on the rocker 107 is movably sleeved with a support spring 106 at the upper end. The rocker 107 is fixedly provided with a No. 1 magnetic ring 108 at the lower end.
[0027] The lower end of the guide post 102 is inclined, and the upper end of the positioning post 113 is inclined, with the two inclined surfaces not in contact and a gap of 1 to 5 centimeters reserved. The upper end of the support spring 106 is fixedly mounted on the lower end of the retaining ring 105, and the lower end of the support spring 106 is fixedly mounted on the upper end of the rocker plate 107. The insert post 114 is movably fitted inside the first magnetic ring 108, and the first magnetic ring 108 and the second magnetic ring 109 repel each other magnetically. The upper end of the buffer damper 103 is fixedly mounted on the lower end of the upper support 3, the upper ends of the side pressure plate 101 and the guide post 102 are fixedly mounted on the lower end of the upper support 3, and the lower end of the positioning post 113 is fixedly mounted on the upper end of the lower support 2. A hydraulic shock absorber 4 is fixedly mounted at the center of the upper surface of the lower support 2, and a constant load support cylinder 5 is fixedly mounted on the upper end of the hydraulic shock absorber 4. The upper end of the constant load support cylinder 5 is fixedly mounted on the lower end of the upper support 3. Both the lower ends of the side pressure plate 101 and the guide post 102 are fixedly equipped with buffer rubber pads. The side pressure plate 101 is located at the upper end of the rocker arm 112 and does not contact it, leaving a gap of 1 cm to 5 cm.
[0028] Specifically, the lower end of the guide column 102 is designed to be inclined, and the upper end of the positioning column 113 is also designed to be inclined. During use, the lower support 2 is pressed down, causing the guide column 102 and the side pressure plate 101 to move downwards. At this time, the inclined surface of the lower end of the guide column 102 contacts the inclined surface of the upper end of the positioning column 113. When the bridge bearing is subjected to various external forces, such as the vibration generated by vehicle traffic, the swaying under wind force, and other dynamic loads that may cause displacement, as well as the influence of environmental factors such as temperature changes and earthquakes, a mutually restraining force will be generated between these two inclined surfaces, preventing the bearing from undergoing lateral or longitudinal displacement. Structurally, this effectively prevents the bearing from shifting and ensures the horizontal stability of the bearing.
[0029] When the side pressure plate 101 moves downward, it will press down the rocker 112, and the rocker 112 is connected to the rocker 107 through the hinge column 111. According to the principle of leverage, the rocker 107 will rise around the hinge point. The movable sleeve at the center of the rocker 107 is provided with an insertion column 114, the upper end of the insertion column 114 is fixed with a retaining ring 105, and the upper end of the retaining ring 105 is fixed with a support column 104. Therefore, the upward thrust of the support column 104 is obtained when the rocker 107 rises. The thrust acts on the upper support 3, and because the upper end of the buffer damper 103 is fixedly arranged at the lower end of the upper support 3, the tightness and stability of the connection between the upper support 3 and the lower support 2 are further enhanced, and the ability of the support to resist deformation and displacement in the vertical direction is improved. Moreover, the movable sleeve on the insertion column 114 is provided with a supporting spring 106, the upper end of the supporting spring 106 is fixed to the lower end of the retaining ring 105, and the lower end is fixed to the upper end of the rocker 107. During the rising of the rocker 107, the supporting spring 106 will be compressed, generating an elastic counterforce, which further enhances the stability. At the same time, the second magnetic ring 109 fixed at the lower end of the insertion column 114 repels the first magnetic ring 108 fixed at the lower end of the rocker 107, and when the rocker 107 rises, the magnetic repulsion will also play a certain buffering and stabilizing role, which will further enhance the overall stability in cooperation with other structures.
[0030] The hydraulic shock absorber 4 is fixedly arranged at the center of the upper end surface of the lower support 2, the upper end of the hydraulic shock absorber 4 is fixed with the dead load support oil cylinder 5, and the upper end of the dead load support oil cylinder 5 is fixedly arranged at the lower end of the upper support 3. The hydraulic shock absorber 4 and the dead load support oil cylinder 5 can provide good support and buffering effect for the bridge support when bearing vertical load. They can adapt to the deformation requirements of the bridge under various dynamic loads and environmental factors, ensure that the load of the superstructure can be reliably and uniformly transmitted to the pier, avoid local stress concentration and damage of the bridge structure due to uneven load transmission, and prolong the service life of the bridge. The lower ends of the side pressure plate 101 and the guide column 102 are fixedly provided with buffer rubber pads. During the operation of the bridge, when subjected to various impact forces, the buffer rubber pads can further absorb and buffer these impact forces, reduce the damage to the bridge structure, and protect the integrity and safety of the bridge structure.
[0031] Working principle: in use, the force of the lower support 2 downwardly presses the guide column 102 and the side pressure plate 101 downwardly, the inclined surface at the lower end of the guide column 102 is in contact with the inclined surface at the upper end of the positioning column 113, which prevents deviation, and at the same time, the downward movement of the side pressure plate 101 presses down the rocker 112, which makes the rocker 107 rise, and the upward thrust of the support column 104 is obtained, which increases the stability.
[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
