Abstract
The utility model belongs to bridge bearing technology field and discloses an anti-seismic spherical steel support. The main technology is characterized in that: the utility model includes an upper support plate, a middle steel plate and a lower support plate, the lower end of the middle steel plate is provided with a short outside, the position of the lower support plate matching with the short outside is provided with a guide sleeve fixed by a pressure plate, the shape of the external end face of the short outside is matched with the shape of the internal end face of the guide sleeve, the internal end face of the guide sleeve is cylindrical, the external end face of the short outside is a convex ring. To the anti-seismic spherical steel support provided by the utility model, when the short outside is relatively rotated with the guide sleeve, the contact surface thereof is always an arc line without any resistant force, the utility model also can ensure the center line of the upper interior components can be always coincident with the steel liner spherical center so that the middle steel plate can be uniformly forced with uneasy damage and long service life.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of shock-proof ball shaped steel bearing.
Background technology
Need to use bridge pad in bridge construction, ball shaped steel bearing especially is because its good performance is widely used especially.Ball shaped steel bearing comprises upper bracket plate, middle steel plate and lower support plate, and lower end of steel plate has long outer in the middle of it, so that when bridge produces displacement bearing is played position-limiting action.The ball shaped steel bearing of this structure, the long outer of middle steel plate when playing position-limiting action, a side perk, opposite side is exerted oneself to lower support plate, thereby makes the middle steel plate unbalance stress easily produce damage, and then influences the application life of whole bearing.
The utility model content
When problem to be solved in the utility model just provides a kind of middle steel plate and plays position-limiting action to the lower support plate uniform shock-proof ball shaped steel bearing of exerting oneself.
For addressing the above problem, the technical scheme that the utility model shock-proof ball shaped steel bearing adopts is: comprise upper bracket plate, middle steel plate and lower support plate, the lower end of described middle steel plate has short outer, being provided with the fixing fairlead of pressing plate with matching part, position, short outer of lower support plate, short outer outer face shape and fairlead inner face shape are complementary.
Its additional technical feature is: the inner face of described fairlead is a cylinder; The outer face of described short outer is a bulge loop; Be provided with the side direction draw runner between described fairlead and lower support plate.
Shock-proof ball shaped steel bearing provided by the utility model compared with prior art is provided with the short outer and the fairlead that are complementary, and the inner face cylinder of fairlead, and the top of short outer is a bulge loop.When relatively rotating with fairlead when short outer, its contact surface is always a camber line, without any resistance, and can guarantee that the center line of upper component overlaps with the steel liner plate centre of sphere all the time, makes middle steel plate stressed even, not fragile.In addition, when slippage took place, fairlead was along the gathering sill slip of seat board and pressing plate composition down, and entire contact surface is all stressed, thereby makes down seat board stressed evenly, increases the service life.And be provided with the side direction draw runner between fairlead and lower support plate, and then can when producing slippage, reduce resistance, play a protective role.
Description of drawings
Accompanying drawing is the structural representation of the utility model shock-proof ball shaped steel bearing.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model shock-proof ball shaped steel bearing.
As shown in the figure, the utility model shock-proof ball shaped steel bearing comprises upper bracket plate 1, middle steel plate 2 and lower support plate 3, the lower end of middle steel plate 2 has short outer 4, the top 41 of short outer 4 is an arc, being provided with the fixing fairlead 6 of pressing plate 5 with matching part, 4 position, short outer of lower support plate 3,3 of fairlead 6 and lower support plate are provided with side direction draw runner 7.
In use, when when short outer 4 relatively rotates with fairlead 6, its contact surface is always a camber line, without any resistance, and the center line that can guarantee upper component overlaps with the steel liner plate centre of sphere all the time, makes middle steel plate 2 stressed evenly, not fragile.In addition, when slippage took place, seat board 3 slided with the gathering sill of pressing plate 5 compositions under fairlead 6 edges, and entire contact surface is all stressed, thereby makes down seat board 3 stressed even, increases the service life.And 3 of fairlead 6 and lower support plate are provided with side direction draw runner 7, then can reduce resistance when producing slippage, play a protective role.
Claims (4)
1. shock-proof ball shaped steel bearing, comprise upper bracket plate, middle steel plate and lower support plate, it is characterized in that: the lower end of described middle steel plate has short outer, being provided with the fixing fairlead of pressing plate with matching part, position, short outer of lower support plate, short outer outer face shape and fairlead inner face shape are complementary.
2. shock-proof ball shaped steel bearing according to claim 1 is characterized in that: the inner face of described fairlead is a cylinder.
3. shock-proof ball shaped steel bearing according to claim 1 is characterized in that: the outer face of described short outer is a bulge loop.
