Description
Technical Field
The utility model relates to an assembled track subtracts vibration isolation technical field, specifically is a split type vibration isolation device.
Background
At present, in the assembled track structure of track traffic, lay the buffer layer in the bottom of assembled track board usually, the buffer layer adopts the elastic backing plate usually, the elastic backing plate is used for absorbing vibration energy, play certain vibration/noise reduction's effect, because the elastic backing plate is flat, for guaranteeing the vibration isolation effect, the bottom surface that needs assembled track board and the top surface of bed plate are the plane, just enable the elastic backing plate and laminate completely between assembled track board and bed plate, the surface requirement to assembled track board and bed plate is higher, cause the increase of assembled track structure's overall cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve the problem that exists among the prior art, provide a split type vibration isolation device, can reduce assembled track structure's manufacturing cost, and can guarantee the travelling comfort when the train lightly carries or does not carry, stability and security when the train heavily carries.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:
a split type vibration isolation device comprises an elastic base plate, wherein a plurality of through holes are vertically formed in the elastic base plate, elastic columns are arranged in the through holes, the heights of the elastic columns are larger than the thickness of the elastic base plate, and gaps are reserved between the outer walls of the elastic columns and the inner walls of the through holes.
Preferably, the elastic column is in a round table shape, the outer diameter of the bottom end of the elastic column is the same as the inner diameter of the through hole, and the outer diameter of the top end of the elastic column is smaller than the inner diameter of the through hole.
Preferably, the top of the elastic column is in a plane or hemisphere shape.
Preferably, the rigidity of the elastic columns is different from that of the elastic backing plates.
Contrast prior art, the beneficial effects of the utility model reside in that:
the top end of the elastic column of the utility model is contacted with the assembled track plate, the bottom end is contacted with the base plate, the original large-area contact is replaced by a plurality of point contacts with small areas, the requirements on the surface smoothness of the assembled track plate and the base plate are lower, and the manufacturing cost of the assembled track structure can be reduced; when the train is lightly loaded or unloaded, the elastic column mainly provides buffer, so that the travelling comfort of the train is ensured by smaller rigidity; when the train is heavily loaded, the elastic column is compressed into the through hole, and the elastic column and the elastic base plate simultaneously provide buffer, so that the stability and the safety of the train operation are ensured with higher rigidity; a gap is reserved between the outer wall of the elastic column and the inner wall of the through hole to reserve allowance for deformation of the elastic column, so that the elastic base plate is prevented from bearing large lateral pressure, and the service life of the elastic base plate is ensured; meanwhile, the number of the elastic columns can be selected as required.

fig. 2 is a cross-sectional view of the present invention.
The reference numbers in the drawings: 1. an elastic backing plate; 2. a through hole; 3. an elastic column.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
Example (b): as shown in the attached fig. 1-2, the utility model relates to a split vibration isolation device, which comprises an elastic backing plate 1, a plurality of through holes 2 are vertically arranged on the elastic backing plate 1, the through holes 2 can be regularly arranged or irregularly arranged, m rows and N columns of through holes 2 can be arranged on the elastic backing plate 1, the number of the through holes 2 can be arranged according to the area of the elastic backing plate 1, the through hole 2 is internally provided with an elastic column 3, the height of the elastic column 3 is greater than the thickness of the elastic base plate 1, the difference between the height of the elastic column 3 and the thickness of the elastic base plate 1 can be set to be 1CM, the top end of the elastic column 3 is contacted with the assembled track plate, the bottom end is contacted with the base plate, the original large-area contact is replaced by a plurality of point contacts with small areas, the requirement on the surface smoothness of the assembled track plate and the base plate is low, and the manufacturing cost of the assembled track structure can be reduced. A gap is reserved between the outer wall of the elastic column 3 and the inner wall of the through hole 2, allowance is reserved for deformation of the elastic column 3, the elastic base plate 1 is prevented from bearing large lateral pressure, and the service life of the elastic base plate is guaranteed.
When the utility model is used, when the train is lightly loaded or unloaded, the elastic column 3 mainly provides buffer, so that the travelling comfort of the train is ensured with smaller rigidity; when the train is heavily loaded, the elastic column 3 is compressed into the through hole 2, and the elastic column 3 and the elastic base plate 1 simultaneously provide buffer, so that the stability and the safety of the train operation are ensured with higher rigidity; meanwhile, the number of the elastic columns 3 required can be selected as required.
Preferably, in order to ensure the stability of the elastic column to the support of the assembled track slab, the elastic column 3 is in a circular truncated cone shape, the outer diameter of the bottom end of the elastic column 3 is the same as the inner diameter of the through hole 2, and the outer diameter of the top end of the elastic column 3 is smaller than the inner diameter of the through hole 2, so that on one hand, stable support can be provided, on the other hand, the area of the top surface of the elastic column 3 is reduced, and the requirement on the surface smoothness of the assembled track slab is reduced.
In order to further reduce the surface smoothness requirement of the assembled track slab, the top of the elastic column 3 is in a plane or semi-sphere shape.
Preferably, in order to meet the driving requirements of trains under different loads, the rigidity of the elastic column 3 is different from that of the elastic base plate 1, the elastic column 3 can be made of rubber or a composite material of polyurethane and fiber, and the elastic base plate 1 can be made of rubber.
