Problems solved by technology

[0002] There are many shock-absorbing supports, such as shock-absorbing supports used in equipment, shock-absorbing supports used in bearing piers, etc. Some of them can only slow down the impact in the vertical direction, and some can slow down the impact in both vertical and horizontal directions. Impact load, but its ability to resist sudden unbalanced load is poor, the amount of deformation is large, the ability to maintain attitude is poor, and the reset is slow

Embodiment 1

[0034] Such as figure 1 with figure 2 As shown, a lower support 2, a lower spring set 6, an adjustment plate 3, an upper spring set 4 and an upper support 1 are arranged in sequence from bottom to top, and a supporting spring is directly connected between the lower support 2 and the upper support 1 Group 5. The adjustment plate 3 includes a support portion extending downwards, such as figure 2 As shown, the support part is an annular support ring 32 , and a rubber pad 31 is also provided on the bottom surface of the support ring 32 .

[0035] The upper support 1 and the lower support 2 are two square supports placed in alignment, the outer ring of the adjustment plate 3 is circular, and the corresponding supporting ring 32 is a circular ring. In fact, the outer ring of the adjusting plate 3 can also be polygonal or square. When the supporting ring 32 is non-circular, its anti-eccentric load capacity in different directions is different. The support ring 32 may be discont...

Embodiment 2

[0044] Such as image 3 As shown in , the upper shock absorber is a rubber pad that includes a protruding dome. The top surface of the adjustment plate 3 includes a concave surface matching the rubber pad. In this way, when the upper support 1 is subjected to an eccentric load, the adjustment plate 3 and the upper support 1 are no longer horizontal but at a certain angle, and the concave surface can provide a more vertical supporting force direction than the plane.

Embodiment 3

[0046] Such as Figure 4 with Figure 5As shown, the support ring 32 is connected to the body of the adjusting plate 3 through a safety rubber 33 , and the compression stroke of the safety rubber 33 is extremely short, which does not affect the overall rigidity of the adjusting plate 3 . When the upper support is stressed and overloaded, the upper spring group 4 has been compressed to the limit, and the support ring 32 is supported on the lower support 2, the body of the adjustment plate 3 can continue to descend relative to the support ring 32, and even cut or pull off the safety rubber , so that the upper support 1 still has a certain descending space, and the probability of overall damage after overloading of this embodiment is reduced as much as possible, so that this embodiment can continue to provide a certain load-bearing and shock-absorbing effect.

Abstract

The invention relates to a shock absorbing bearing, which comprises an upper bearing, a lower bearing, an adjusting plate, an upper shock absorber and a lower shock absorber. The regulating plate is connected with the upper support through the upper shock absorber, and the regulating plate is connected with the lower support through the lower shock absorber. The support part is located under the adjusting plate and on the outer periphery of the lower shock absorber, and the distance between the support part and the lower support is smaller than the shock absorber stroke. Between that support and the low support, a shock absorbing pad is included. The shock absorbing bearing provided by the invention has the advantages that the upper bearing is decelerated, the distance of the upper bearingdeviating from the original position is shorter than the time when the support part is not provided, and the vibration of the upper bearing is reduced. The invention can better maintain the posture when the load is biased, and the vibration is effectively absorbed. At the same time, the shock absorption effect of the sudden change load is good. The asynchronous motion of the upper shock absorberand the lower shock absorber absorbs part of the vibration of the upper bearing to the hanging regulating plate, and transmits the vibration to the lower bearing with time delay.

Description

technical field [0001] The invention relates to the field of support seats, in particular to a shock-absorbing support. Background technique [0002] There are many shock-absorbing supports, such as shock-absorbing supports used in equipment, shock-absorbing supports used in bearing piers, etc. Some of them can only slow down the impact in the vertical direction, and some can slow down the impact in both vertical and horizontal directions. Impact load, but its ability to resist sudden unbalanced load is poor, the amount of deformation is large, the ability to maintain attitude is poor, and the reset is slow. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a shock-absorbing support that has a good shock-absorbing effect and can stably resist abrupt loads. [0005] (2) Technical solutions [0006] In order to achieve the above object, the present...
