Abstract
The utility model discloses a spherical bearing for a bridge in order to prolong the service life of the bearing. The spherical bearing comprises an upper anchor plate (10), a wear-resisting plate (11), a spherical crown lining plate (23), a lower anchor plate (20) and a lower bearing plate (21) and is characterized in that a turning block assembly (12) is arranged between contact surfaces of the upper anchor plate (10) and the lower bearing plate (21); the upper anchor plate (10) and the turning block assembly (12) are in sliding fit; and the lower bearing plate (21) and the turning block assembly (12) form a friction pair. The spherical bearing has the beneficial effects that when the bearing rotates, the lower bearing plate is always in close contact with the arc surface of the turning block assembly, the turning block assembly is always in half-surface contact with the upper anchor plate, and the stress is uniform, thereby prolonging the service life of the bearing.
Description
Technical field
The utility model relates to a kind of bridge pad.
Background technology
Spherical bearing is a kind of novel bridge bearing that grows up on the basis of pot rubber bearing, has that level angle is big, characteristics of high-bearing capacity, abrasion performance.The corner of spherical bearing is to realize with relative slip between the sphere by spherical crown, relative slip between plane tetrafluoro plate and the corrosion resistant plate realizes the horizontal movement of bearing, rely on the horizontal force action of basin ring or baffle plate opposing earthquake, can effectively resist the earthquake horizontal force in low seismic intensity area.
On existing unidirectional movable spherical bearing, the upper bracket plate directly contacts the transmission horizontal force with lower support plate, and contact surface is provided with slide plate and corrosion resistant plate to adapt to the support displacement requirement.When beam-ends rotated, upper bracket plate and lower support plate be the keeping parallelism state no longer, made contacting by face contact becoming line of slide plate and corrosion resistant plate contact, and caused sled surface inhomogeneous stressed, caused the broken ring of extruding.
The utility model content
Technical problem to be solved in the utility model provides a kind of bridge spherical bearing, makes its sled surface stressed evenly, thereby prolongs the application life of bearing.
The technical scheme that its technical problem that solves the utility model adopts is: bridge spherical bearing of the present utility model, last anchor plate, wearing plate, spherical crown liner plate, following anchor plate and lower support plate, its feature is being: described going up between anchor plate and the lower support plate contact surface is provided with the moving block assembly, last anchor plate and moving block assembly form and are slidingly matched, and lower support plate then forms friction pair with the moving block assembly.
The beneficial effects of the utility model are, when bearing rotated, lower support plate closely contacted all the time with the cambered surface of moving block assembly, and the moving block assembly remains demifacet with last anchor plate and contacts, stressed evenly, thereby prolong application life of bearing.
Description of drawings
This manual comprises as next width of cloth accompanying drawing:
Fig. 1 is the structural representation of the utility model bridge spherical bearing.
Component names shown in the figure and pairing mark: go up anchor plate 10, wearing plate 11, moving block assembly 12, following anchor plate 20, lower support plate 21, wearing plate 22, spherical crown liner plate 23.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, bridge spherical bearing of the present utility model, last anchor plate 10, wearing plate 11, spherical crown liner plate 23, following anchor plate 20 and lower support plate 21.Described going up between anchor plate 10 and lower support plate 21 contact surfaces is provided with moving block assembly 12, and last anchor plate 10 forms with moving block assembly 12 and is slidingly matched, and 21 of lower support plate and moving block assembly 12 form friction pairs.Described moving block assembly 12 forms with last anchor plate 10 and is slidingly matched, and its contact surface is a cambered surface.Have friction pair on the contact surface between described moving block assembly 12 and the lower support plate 21, this friction pair is made of slide plate and corrosion resistant plate, is fixedly installed on respectively on moving block assembly 12 and the lower support plate 21.
When beam-ends rotates, because the contact surface between moving block assembly 12 and the lower support plate 21 is a cambered surface, it is suitable with the angle of rotating, thus can remain the face contact, between moving block assembly 12 and last anchor plate 10 and all kept face to contact between the friction pair.
