Technical Field

[0001] The utility model relates to the technical field of shock-absorbing supports, in particular to a shock-absorbing support for roads and bridges. Background Art

[0002] A shock-absorbing bearing is a device used to reduce or absorb the vibration and displacement of a structure caused by an earthquake, wind or other dynamic loads. Its main function is to isolate the direct effect of seismic waves on the building and reduce the transmission of seismic energy to the building, thereby protecting the safety of the building. A shock-absorbing bearing usually consists of a bearing body, an elastic element and a damping element.

[0003] At present, the shock-absorbing bearings used in roads and bridges are mostly of simple structure and have poor shock-absorbing effect, which can easily cause large vibrations of roads and bridges under the action of external forces, causing serious damage to the structures of roads and bridges. This will not only increase the risk of road and bridge collapse and cause accidents, but also increase the maintenance cost and time of shock-absorbing bearings. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is in use, the road and bridge are easily damaged and the maintenance cost and time are increased due to the poor effect of the shock-absorbing support, thereby proposing a shock-absorbing support for roads and bridges.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a shock-absorbing support for a road bridge, comprising a shock-absorbing mechanism, the outer surface wall of which is fixedly mounted with a protective mechanism;

[0006] The shock absorbing mechanism includes a base plate, four first springs are fixedly installed on the top of the base plate, four first dampers are fixedly installed on the top of the base plate, a support column is fixedly installed between the tops of the four first dampers, and the bottom of the support column is fixedly connected to the top of the four first springs, a steel plate is fixedly installed on the top of the support column, a rubber shock-absorbing pad is arranged on the top of the steel plate, four sliding grooves are opened on the top of the base plate, second springs are fixedly installed on one side of the inner wall of the four sliding grooves, sliders are movably embedded in the inner walls of the four sliding grooves, and one side of the outer wall of the four second springs is fixedly connected to one side of the outer wall of the slider.

[0015] 2. In the utility model, under the action of the protective mechanism, the four baffles can provide protection for the shock-absorbing support, prevent external debris from damaging the internal parts of the shock-absorbing support, and extend the service life of the shock-absorbing support.

DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a shock-absorbing support for a road bridge, comprising a shock-absorbing mechanism 1, and a protective mechanism 2 is fixedly installed on the outer wall of the shock-absorbing mechanism 1;

[0025] The shock absorbing mechanism 1 includes a bottom plate 101, four first springs 102 are fixedly installed on the top of the bottom plate 101, four first dampers 103 are fixedly installed on the top of the bottom plate 101, a support column 104 is fixedly installed between the tops of the four first dampers 103, and the bottom of the support column 104 is fixedly connected to the tops of the four first springs 102, a steel plate 105 is fixedly installed on the top of the support column 104, a rubber shock absorbing pad 106 is arranged on the top of the steel plate 105, four slide grooves 107 are opened on the top of the bottom plate 101, second springs 108 are fixedly installed on one side of the inner wall of the four slide grooves 107, sliders 109 are movably embedded in the inner surface walls of the four slide grooves 107, and the four second springs 108 One side of the outer wall is fixedly connected to one side of the outer wall of the slider 109, a group of first ear blocks 110 are fixedly installed on the top of the four sliders 109, the outer walls of the four groups of first ear blocks 110 are each provided with a group of first holes 111, and the inner walls of the four groups of first holes 111 are each movably inserted with a first rotating shaft 112, the outer walls of the four first rotating shafts 112 are each fixedly sleeved with a force arm 113, the outer walls of the four force arms 113 are each provided with a second hole 114, the inner walls of the four second holes 114 are each fixedly inserted with a second rotating shaft 115, the outer walls of the four second rotating shafts 115 are each movably sleeved with a group of second ear blocks 116, and the tops of the four groups of second ear blocks 116 are fixedly connected to the bottom of the support column 104.

[0026] The effect achieved by the entire embodiment 1 is that when the road bridge is subjected to external force, the kinetic energy will be transferred to the shock-absorbing support. At this time, the rubber shock-absorbing pad 106 absorbs part of the kinetic energy, and the steel plate 105 below can increase the stability of the shock-absorbing support structure. Then, the support column 104 begins to descend under the force, driving the first spring 102 and the first damper 103 below to shrink most of the kinetic energy. When the support column 104 descends, it will also drive the second ear block 116 to begin to descend. The second ear block 116 will drive the power arm 113 and the first ear block 110 to begin to move, so that the slider 109 begins to squeeze the second spring 108, eliminating the remaining kinetic energy, and protecting the safety of the road bridge structure to the greatest extent through multi-stage shock absorption, thereby reducing the occurrence of accidents.

[0027] Embodiment 2, as Figure 2-Figure 4 As shown, the protective mechanism 2 includes four groups of second dampers 201, baffles 202 are fixedly installed between the outer walls of the four groups of second dampers 201, a group of third springs 203 are fixedly installed on one side of the outer walls of the four baffles 202, the outer wall of the support column 104 is fixedly connected to the outer walls of the four groups of second dampers 201, and the outer wall of the support column 104 is fixedly connected to the outer walls of the four groups of third springs 203.

[0028] The effect achieved by the entire embodiment 2 is that when the shock-absorbing support is hit by external impact, the baffle 202 will protect the internal parts of the shock-absorbing support. At the same time, the baffle 202 will move inward to squeeze the second damper 201 and the third spring 203. The second damper 201 and the third spring 203 will absorb the relevant kinetic energy, avoid damage to the internal structure of the shock-absorbing support, and extend the service life of the shock-absorbing support.

[0029] Working principle: When the road bridge begins to vibrate, the kinetic energy will be transferred to the rubber shock-absorbing pad 106, and the rubber shock-absorbing pad 106 and the steel plate 105 will absorb part of the kinetic energy. Then the remaining kinetic energy will drive the support column 104 to start to descend. When the support column 104 descends, it will begin to squeeze the first spring 102 and the first damper 103. The first spring 102 and the first damper 103 will absorb most of the kinetic energy by contraction. When the support column 104 descends, it will drive the second ear block 116 to descend together. The second ear block 116 will cause the second rotating shaft 115 to start to move. The first ear block 110 moves outwards together with the first shaft 112. When the first ear block 110 moves outwards, it drives the slider 109 to slide in the slide groove 107 and squeeze the second spring 108. The second spring 108 absorbs the remaining kinetic energy by shrinking. When the shock-absorbing support is hit, the baffle 202 starts to shrink inwards and squeezes the second damper 201 and the third spring 203 to protect the shock-absorbing support.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
