Abstract
A spheroidal steel support saddle comprises an upper anchor steel bar, an upper support plate, an abrasion-resistant plate, a spherical cap lining plate, another abrasion-resistant plate, a lower support plate, an lower anchor plate and a lower anchor steel bar, wherein a turning block component is arranged between the contact surfaces of the upper support plate and the lower support plate, either the upper support plate or the lower support plate is in slide fit with the turning block component, and a friction pair is arranged on the surface of the other support plate in contact with the turning block component. When the support saddle rotates, the lower support plate is always in close contact with a cambered surface of the turning block, and the turning block and the upper support plate are always in planar contact. Therefore, the problem of uneven stress in the prior art is overcome, and the service life of the product is prolonged.
Description
Technical field
The utility model relates to bridge technology, particularly a kind of bridge pad.
Background technology
Ball shaped steel bearing is succeeded in developing the seventies abroad.Rose in 1988 and begin to apply in the domestic bridge.Ball shaped steel bearing is a kind of novel bridge bearing that grows up on the basis of pot rubber bearing.Be characterized in that level angle is big, high-bearing capacity, abrasion performance.
The corner of ball shaped steel bearing is realized 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.Be applicable to the various bridge under the low seismic intensity.
Ball shaped steel bearing is the horizontal force action that relies on basin ring or baffle plate opposing earthquake, can effectively resist the earthquake horizontal force in low seismic intensity area.Nanpu, Shanghai cable stayed bridge, Beijing Gate of Pervasive Peace, Temple of Heavenly Tranquility overpass bridge etc. are the bridges that uses ball shaped steel bearing in early days at home, and ball shaped steel bearing has been widely used in public affairs, the railway engineering now, is one of topmost support style.
Existing unidirectional movable ball shaped steel bearing upper bracket plate directly contacts the transmission horizontal force with lower support plate, and contact surface is provided with SF-1 slide plate and corrosion resistant plate to adapt to the support displacement requirement.When beam-ends rotated, upper bracket plate and lower support plate made contacting by face contact becoming line of SF-1 slide plate and corrosion resistant plate contact not at the keeping parallelism state, cause the SF-1 sled surface inhomogeneous stressed, cause the broken ring of extruding.
The utility model content
Technical problem to be solved in the utility model is, a kind of novel ball shaped steel bearing is provided, and can effectively solve the problem of the friction pair sled surface discontinuity of prior art.
The technical scheme that the present invention solve the technical problem employing is, ball shaped steel bearing, comprise anchorage rod iron, upper bracket plate, wearing plate, spherical crown liner plate, wearing plate, lower support plate, following anchor plate and following anchorage rod iron, between upper bracket plate and lower support plate contact surface, be provided with the moving block assembly, upper bracket plate and lower support plate the two one of form with the moving block assembly and be slidingly matched, the contact surface between another and the moving block assembly is provided with friction pair.
Specifically, moving block assembly and upper bracket plate form and are slidingly matched, and its contact surface is a cambered surface; Contact surface between moving block assembly and the lower support plate is provided with friction pair; Described friction pair is made of SF-1 slide plate and corrosion resistant plate, is fixedly installed on respectively on moving block assembly and the lower support plate.
Perhaps, moving block assembly and lower support plate form and are slidingly matched, and its contact surface is a cambered surface; Contact surface between moving block assembly and the upper bracket plate is provided with friction pair, and described friction pair is made of SF-1 slide plate and corrosion resistant plate, is fixedly installed on respectively on moving block assembly and the upper bracket plate.
The beneficial effects of the utility model are, ball shaped steel bearing of the present utility model has added moving block between upper and lower seat board, the contact surface of moving block and lower support plate is a curved surface, SF-1 slide plate and corrosion resistant plate friction pair are located between moving block and the upper bracket plate, when bearing rotated, lower support plate closely contacted all the time with the cambered surface of moving block, and moving block and upper bracket plate remain plane contact, overcome the problem of the discontinuity of prior art, prolonged the application life of product.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Prior art such as Fig. 3 a, Fig. 3 b, when beam-ends rotated, upper bracket plate and lower support plate made contacting by face contact becoming line of SF-1 slide plate and corrosion resistant plate contact not at the keeping parallelism state.
The utility model such as Fig. 3 c, Fig. 3 d, when beam-ends rotates, because the moving block assembly and the contact surface between the lower support plate of present embodiment are cambered surface, it is suitable with the angle of rotating, so can remain the face contact, between moving block and upper bracket plate, and all kept the face contact between the friction pair.
Embodiment 2:
The difference of present embodiment and embodiment 1 is that friction pair is arranged on the contact surface of moving block assembly 5 and lower support plate 7, and moving block assembly 5 is a cambered surface with the contact surface of upper bracket plate 2, and its operating principle is similar to Example 1.
