Pad）With lower support plate etc.；Upper bracket plate therein, spherical crown（Middle steel plate）It is usually steel with lower support plate material therefor, such as
The steel alloys such as cast steel or Q345, therefore its cost is higher, expensive, economic benefit is relatively low.
Invention content
The purpose of this utility model is that being directed to the defects of existing bridge pad cost is higher, expensive, one is provided
Kind spheroidal graphite cast-iron bridge pad.
To achieve the above object, institute is the utility model using technical solution：A kind of spheroidal graphite cast-iron bridge pad, packet
Include spherical crown and the upper bracket plate being made by ductile cast iron material, lower support plate, the upper bracket plate top and undersetting
Plate bottom is respectively arranged with anchorage rod iron, and wearing plate, the upper bracket are provided between the upper bracket plate and spherical crown
Stainless steel plate is provided between plate and upper wearing plate, lower wearing plate is provided between the spherical crown and lower support plate.
The spherical crown is made by ductile cast iron material.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model includes spherical crown and the upper bracket plate being made by ductile cast iron material, lower support plate, i.e.,
It is spheroidal graphite cast-iron that upper bracket plate, which closes lower support plate material therefor, which has good physical mechanical property,
Intensity and the intensity of cast steel are comparable, and with higher yield strength, corrosion resistance and inoxidizability are above cast steel；Together
When, due to the globular graphite microstructure of spheroidal graphite cast-iron, in terms of damping vibration ability, spheroidal graphite cast-iron is better than cast steel, therefore more
Add and advantageously reduce stress, therefore improve product quality.
2nd, the utility model includes spherical crown and the upper bracket plate being made by ductile cast iron material, lower support plate, should
Generally cheap compared with cast steel 1/3, cheap compared with forged steel 1/5~2/5；Manufacture spheroidal graphite cast-iron simultaneously needs to refine unlike cast steel or forged steel
Steel equipment and complicated forging equipment, common mechanical manufacture and repairing factory can be produced with regard to original iron foundry (shop)；And
Newly-built and enlarging workshop also can be that country saves great deal of steel, therefore manufacture letter than expanding cast steel and forged steel comes fast and economical
Just, cost is reduced.
Description of the drawings
Fig. 1 is pot bearing structure diagram in the utility model.
Fig. 2 is spherical bearing structure diagram in the utility model.
Fig. 3 is hyperboloid friction pendulum support structure diagram in the utility model.
In figure, spherical crown 1, upper bracket plate 2, lower support plate 3, anchorage rod iron 4, upper wearing plate 5, stainless steel plate 6, lower wearing plate

Specific embodiment
The utility model is described in further detail below in conjunction with description of the drawings and specific embodiment.
Referring to Fig. 1 to Fig. 3, a kind of spheroidal graphite cast-iron bridge pad is made including spherical crown 1 and by ductile cast iron material
Upper bracket plate 2, lower support plate 3.2 top of upper bracket plate and 3 bottom of lower support plate is respectively arranged with anchorage rod iron 4, institute
Wearing plate 5 is provided between the upper bracket plate 2 and spherical crown 1 stated, is provided between the upper bracket plate 1 and upper wearing plate 5
Stainless steel plate 6 is provided with lower wearing plate 7 between the spherical crown 1 and lower support plate 3.
Referring to Fig. 1 to Fig. 3, further, the spherical crown 1 is made by ductile cast iron material.
Spheroidal graphite cast-iron refer to iron liquid in process of setting carbon with the cast iron of ball-type Graphite Precipitation；The change of spheroidal graphite cast-iron than iron
It studies point and to be usually：Phosphorus content 3.0~4.0%, silicon content 1.8~3.2% are no more than 3.0% and suitable containing manganese, phosphorus, sulphur total amount
The nodularizations element such as rare earth, magnesium.Spheroidal graphite cast-iron static strength and wear-resisting property are not only much higher than grey cast-iron, inoculation cast iron, conjunction
Golden cast iron and malleable cast iron, and part is better than No. 45 steel.Compared with gray cast iron, the maximum of Spheroidal Graphite Cast Iron Metallographic Structure tissue is not both stone
The change of black shape avoids the presence of sharp graphite in gray cast iron so that graphite greatly subtracts the cutting action of metallic matrix
It is few, stress concentration phenomenon caused by essentially eliminating flake graphite so that the rate of utilization of strength of metallic matrix reaches 70-90%, from
And the performance of metallic matrix is made to obtain very big performance.Therefore, spheroidal graphite cast-iron is comprehensive as a kind of high-strength cast iron material
Can be close to steel, it has preferable physical mechanical property, can as steel by heat treatment and the measures such as alloying come
Its performance is further improved, for example, processed spheroidal graphite cast-iron can obtain good toughness, elongation percentage is up to 24%, resists
Tensile strength can be up to 1400Mpa, substantially close to steel；Simultaneously compared with steel, spheroidal graphite cast-iron also has many good qualities, for example casts
Make good, advantage of lower cost of performance etc..
