DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary technical personnel in the art without creative labor belong to the scope of protection of the utility model.

[0026] Embodiment: refer to Figures 1-4The illustrated high-damping shock-absorbing support comprises two mounting steel plates 1, a damping main body 2 fixed between the two mounting steel plates 1, and a rubber protective layer 3 sleeved around the damping main body 2. The damping main body 2 is a prior art, which is formed by interlacing and vulcanizing a plurality of steel plates and a plurality of rubber layers, and has high damping performance and good shock-absorbing effect. The upper and lower ends of the damping main body 2 are fixed with the mounting steel plates 1 through end plates 4;

[0027] The outer side of the rubber protective layer 3 movably sleeves two mounting ring plates 5 distributed above and below. The inner diameter of the mounting ring plate 5 is larger than the outer diameter of the rubber protective layer 3, and the two mounting ring plates 5 are coaxially arranged with the damping main body 2.

[0028] The side of each of the two mounting steel plates 1 close to each other is provided with a plurality of groups of radial counteracting structures 6. The upper and lower mounting ring plates 5 are elastically connected with the upper and lower mounting steel plates 1 through a plurality of groups of radial counteracting structures 6. The extension direction of the radial counteracting structure 6 is consistent with the radial direction of the damping main body 2.

[0029] The two mounting ring plates 5 are elastically connected through an axial damping structure 7. The relative movement direction between the two mounting ring plates 5 is consistent with the axial direction of the damping main body 2.

[0030] Based on the above structure, by arranging a plurality of groups of radial counteracting structures 6, the damping shock-absorbing support obtains higher deformation resistance in the radial direction, so that the damping shock-absorbing support obtains better horizontal damping and shock-absorbing effect. Meanwhile, the radial counteracting structure 6 can assist the damping main body 2 to reset, so as to improve the resetting performance of the damping main body 2 after deformation, which is beneficial to maintaining good shock-absorbing effect. Meanwhile, the arrangement of the axial damping structure 7 enhances the damping effect of the damping shock-absorbing support in the axial direction, so as to enhance the vibration energy dissipation capacity in the axial direction, thereby enhancing the comprehensive shock-absorbing performance of the high-damping shock-absorbing support.

[0031] Further, the inner side of the mounting ring plate 5 is integrally formed with a vertically extending extension lip plate 51. There is a gap between the inner side of the extension lip plate 51 and the outer side of the rubber protective layer 3, and the gap width is 10-50mm. The central axis of the extension lip plate 51 coincides with the axis of the damping main body 2. The arrangement of the extension lip plate 51 enlarges the contact area between the mounting ring plate 5 and the rubber protective layer 3. When the damping main body 2 deforms, the rubber protective layer 3 deforms accordingly. The extension lip plate 51 can counteract the deformation of the damping main body 2 under the action of the radial counteracting structure 6, so that the damping main body 2 and the radial counteracting structure 6 generate better energy dissipation effect through the force of the mounting ring plate 5, thereby enhancing the auxiliary resetting effect of the damping main body 2 and enhancing the damping performance and shock-absorbing effect of the damping shock-absorbing support.

[0032] Further, the radial opposing structure 6 comprises a fixed plate 61 and a spring 62, the fixed plate 61 is fixed to the side of the mounting steel plate 1 close to the mounting ring plate 5, one end of the spring 62 is fixed to one side of the fixed plate 61, the other end of the spring 62 is fixed to the outer side of the extension lip plate 51 away from the rubber protection layer 3, and the central axis of the spring 62 is consistent with the radial direction of the damping main body 2;

[0033] The side of the fixed plate 61 away from the mounting steel plate 1 abuts against the side wall of the mounting ring plate 5, and the side of the fixed plate 61 abutting against the mounting ring plate 5 is in interference fit with the surface of the mounting ring plate 5.

[0034] Through the setting of the fixed plate 61 and the spring 62, when the damping main body 2 deforms, the rubber protection layer 3 deforms and abuts against the extension lip plate 51 on the inner side of the mounting ring plate 5, at this time, the spring 62 applies a spring force to the extension lip plate 51 to resist the deformation of the damping main body 2 and is compressed to store energy, and then when the damping main body 2 deforms in the opposite direction, the spring 62 releases energy, thereby enhancing the horizontal energy dissipation effect of the damping main body 2 through the fixed plate 61 and the spring 62, and when multiple springs 62 and multiple fixed plates 61 jointly apply force to the extension lip plate 51, an external damping effect is generated, in addition, after the damping main body 2 deforms, the extension lip plate 51 can be pressed against the rubber protection layer 3 under the action of the spring force of the spring 62, thereby assisting the damping main body 2 to reset.

[0035] Further, the axial damping structure 7 comprises a damping cylinder 71, a piston rod 72 and a damping plate 73, the damping cylinder 71 is integrally formed with the two sides of the two mounting ring plates 5 close to each other, and the two damping cylinders 71 are both closed cylinders filled with damping liquid inside;

[0036] The upper and lower ends of the piston rod 72 slide through the ends of the two damping cylinders 71 close to each other, the end of the piston rod 72 extends into the damping cylinder 71 and is integrally formed with the damping plate 73, and the damping plate 73 is provided with a damping hole 731 for the damping liquid to pass through;

[0037] The axial damping structure 7 is also provided with multiple groups, and the multiple groups of axial damping structures 7 are distributed in a circular array along the axis of the damping main body 2.

[0038] When axial vibration occurs, the distance between the two mounting ring plates 5 changes, so that the distance between the two damping cylinders 71 that move synchronously with the two mounting ring plates 5 changes, at this time, the piston rod 72 produces relative movement with the two damping cylinders 71, so that the damping plate 73 produces relative movement in the two damping cylinders 71, and the damping liquid passes through the damping hole 731 during movement, thereby producing vertical damping effect, that is, damping effect consistent with the axial direction of the damping body 2, so that vertical tensile force is generated between the two mounting steel plates 1 through the elastic force of the two mounting ring plates 5 and the spring 62 and the fixed plate 61, thereby increasing the vertical energy dissipation effect of the damping shock-absorbing support and enhancing the anti-seismic effect of the damping shock-absorbing support.

[0039] The working principle of the damping shock-absorbing support is as follows: in the daily use process, when an earthquake occurs, the damping body 2 deforms radially and axially to achieve good damping effect, and the rubber protective layer 3 deforms and abuts against the extension lip plate 51 on the inner side of the mounting ring plate 5 at this time, at this time, the spring 62 exerts elastic force against the deformation of the damping body 2 and is compressed to store energy, and then when the damping body 2 deforms in the opposite direction, the spring 62 releases energy, thereby enhancing the horizontal energy dissipation effect of the damping body 2 through the fixed plate 61 and the spring 62, and when the multiple springs 62 and the multiple fixed plates 61 jointly exert force on the extension lip plate 51, external damping effect is produced, in addition, after the damping body 2 deforms, the extension lip plate 51 can be pressed against the rubber protective layer 3 under the elastic force of the spring 62, thereby achieving the effect of assisting the damping body 2 to return to the original position; when axial vibration occurs, the distance between the two mounting ring plates 5 changes, so that the distance between the two damping cylinders 71 that move synchronously with the two mounting ring plates 5 changes, at this time, the piston rod 72 produces relative movement with the two damping cylinders 71, so that the damping plate 73 produces relative movement in the two damping cylinders 71, and the damping liquid passes through the damping hole 731 during movement, thereby producing vertical damping effect, that is, damping effect consistent with the axial direction of the damping body 2, so that vertical tensile force is generated between the two mounting steel plates 1 through the elastic force of the two mounting ring plates 5 and the spring 62 and the fixed plate 61, thereby increasing the vertical energy dissipation effect of the damping shock-absorbing support and enhancing the comprehensive damping performance of the high-damping shock-absorbing support.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the damping shock-absorbing support and is not intended to limit the damping shock-absorbing support, although the damping shock-absorbing support has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement of some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the damping shock-absorbing support shall be included in the protection scope of the damping shock-absorbing support.
