Abstract
The utility model relates to a high-elasticity polyester shock absorption cushion plate, which is used for reducing vibration and noise from tracks. The cushion plate comprises a cushion plate body (1); and upper and lower surfaces of the cushion plate body (1) are both provided with a plurality of bosses (2). The cushion plate is characterized in that: the plurality of bosses (2) on the upper surface are arranged in a rectangular shape; the bosses (2) are quadrangular tables; the edges of the two adjacent bosses (2) are overlapped to each other; and the bosses (2) on the lower surface of the cushion plate body (1) are misplaced with the upper surface. The high-elasticity polyester shock absorption cushion plate is low in rigidity, quick in elasticity recovery speed, long in service life and favorable for environment protection.
Description
Technical field
The utility model relates to the backing plate in a kind of track traffic middle orbit fastener system, relates in particular to a kind of high resiliency polyester vibration attenuation pad, is used to reduce the vibration and the noise of track.Belong to track traffic fastener antivibration area.
Background technology
In recent years, the construction of track traffic (subway, state's iron, high ferro) is in the ascendant, and at present circuit is basically for ballastless track designs, so how to reduce track vibration and noise becomes the problem that people receive much concern always.Temperature difference urban rail transit construction big, the area that makes a clear distinction between the four seasons objectively requires the fastener backing plate to have universality; Backing plate can adapt under the bigger situation of the temperature difference and still has constant basically elastic performance, and length fatigue life of backing plate also is the eternal pursuit of user certainly.
Vibration attenuation pad commonly used at present mainly contains low rigidity rubber mat plate and the high-elastic backing plate of plough groove type polyester elastomer.Low its material of rigidity rubber mat plate is softer, and it is slow that deformation recovers, moving/quiet ratio of rigidity is bigger, and fatigue performance is bad; The two provides elasticity simultaneously though the high-elastic backing plate of plough groove type polyester elastomer can utilize deflection and compressive deformation simultaneously, and deformation recovered faster, its structure are unidirectional upper and lower surface dislocation groove structure, make backing plate have stronger anisotropy.Particularly under the effect of vertical force, less along the lateral deformation amount of groove direction, the deformation quantity of vertical trench direction is bigger, causes the assembling rigidity of fastener system higher, can influence the comprehensive result of use of fastener system to a certain extent.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides that a kind of rigidity is low, elastic return speed is fast, long service life, environmentally friendly high resiliency polyester vibration attenuation pad.
The purpose of the utility model is achieved in that a kind of high resiliency polyester vibration attenuation pad; It comprises the backing plate body; The upper and lower surface of said backing plate body is provided with a plurality of boss, the rectangular arranged in arrays of a plurality of boss of said upper surface, and said boss is a truncated rectangular pyramids; Overlap each other between the rib of said adjacent two boss and the rib, the boss and the upper surface of said backing plate body soffit shift to install.
Said boss is the rhombus truncated rectangular pyramids.Be preferably positive truncated rectangular pyramids.
Compared with prior art, the beneficial effect of the utility model is:
The utility model high resiliency polyester vibration attenuation pad, the last plane of terrace with edge is a load-carrying surface, under the effect of vertical force; Four sides of terrace with edge mainly produce flexural deformations; Adopt the connected mode of overlap joint between the rib of adjacent two terrace with edges and the rib, dwindled the stress concentration of shearing force, reduced the destruction of shearing force pad; Prolong its application life, reduced the maintenance, repair workload of circuit.
Adopt the utility model high resiliency polyester vibration attenuation pad, the especially positive truncated rectangular pyramids of truncated rectangular pyramids gets the rectangular array formula and arranges that its anisotropy is less, makes the dynamic stiffness of backing plate reduce, and then sleeper, roadbed and destruction of bridge power is reduced when making vehicle operating.
In addition, the recycling of inefficacy backing plate is convenient, helps environmental protection.

The specific embodiment
Referring to Fig. 1 ~ 4, Fig. 1 is the Facad structure sketch map of the utility model high resiliency polyester vibration attenuation pad.Fig. 2 is the upward view of Fig. 1.Fig. 3 is the A-A sectional view of Fig. 1.Fig. 4 is the B portion enlarged drawing of Fig. 1.Can find out by Fig. 1 to Fig. 4; The utility model high resiliency polyester vibration attenuation pad comprises backing plate body 1, and said backing plate body 1 upper and lower surface is provided with a plurality of boss 2; The a plurality of boss 2 rectangular arranged in arrays of said upper surface; Said boss 2 is a truncated rectangular pyramids, overlaps each other between the rib of said adjacent two boss 2 and the rib, and the boss 2 and the upper surface of said backing plate body 1 soffit shift to install.
Said boss 2 is preferably the rhombus truncated rectangular pyramids, and optimum is positive truncated rectangular pyramids.
The rigidity of the utility model high resiliency polyester vibration attenuation pad can be regulated through changing the length that overlaps between terrace with edge top surface area size, adjacent two terrace with edge ribs and the rib and the gradient of terrace with edge side.Can produce the low high-elastic backing plate of rigidity with macromolecular material, improve the supporting capacity and the fatigue performance of backing plate, make it to have good comprehensive functional performance with the bent modulus of higher change.
