Description
Technical field
The utility model relates to bridge pad, specifically is the unidirectional freely movable bearing of a kind of shock-proof ball.
Background technology
Two spherical bearings are the external friction pendulum support of a kind of reference (FPS) principles, utilize moving, potential energy transforming principle, earthquake kinetic energy is converted into gravitional force, thereby weakens earthquake to the bridge collapse bearing.There is inevitable defective in common two balls (song) face bearing: 1, nominal situation and earthquake operating mode all adopt same group of friction pair, and design parameters is obscured, and can not satisfy two kinds of demands under the operating mode simultaneously.2, under nominal situation, bridge generation normal displacement not only will overcome the frictional resistance of support friction pair, also will overcome the beam body simultaneously and focus on the component on the bearing sphere certainly, and this component is also bigger.Therefore, the normal displacement of bridge is a greater impact.3, the bearing vertical height frequently changes, and to the body of a bridge generation time internal force of statically determinate structrue, long term will produce bigger influence to bridge.
The utility model content
The purpose of the utility model is the deficiency that overcomes above-mentioned existence, and a kind of simple in structure, easy to operate, safety, the unidirectional freely movable bearing of shock-proof ball that shock resistance is good are provided.
The technical scheme that the utility model adopted is:
The unidirectional freely movable bearing of a kind of shock-proof ball; It comprises upper bracket plate, bulb flat, concave face plate, damping rubber circle and lower support plate; It is characterized in that being provided with bulb flat and concave face plate between said upper bracket plate and the lower support plate, be provided with plane tetrafluoro slide plate between said bulb flat and the upper bracket plate, be provided with spherical tetrafluoro slide plate between bulb flat and the concave face plate; Also be provided with the sealing ring I on the said bulb flat, also be provided with the damping rubber circle between said concave face plate and the lower support plate.
According to the unidirectional freely movable bearing of the described shock-proof ball of the utility model, it is characterized in that also being provided with between said concave face plate and the lower support plate sealing ring II.
According to the unidirectional freely movable bearing of the described shock-proof ball of the utility model, it is characterized in that said concave face plate lateral surface and upper bracket plate adjacent are provided with side tetrafluoro slide plate.
According to the unidirectional freely movable bearing of the described shock-proof ball of the utility model, it is characterized in that the tetrafluoro slide plate corresponding position, side of said upper bracket plate medial surface and concave face plate is provided with side stainless steel slide plate.
The utility model is the unidirectional freely movable bearing of a kind of shock-proof ball, through between concave face plate and lower support plate, also being provided with the damping rubber circle, adopts sphere friction pair and plane friction pair simultaneously, thereby reaches the purpose of damping antidetonation.Therefore the utlity model has advantages such as property simple in structure, easy to use, safe is good.
