Summary of the invention:
In order to overcome the deficiency in the background technology, the utility model discloses a kind of universal ball foundry goods vibration absorption and isolation support, described universal ball foundry goods vibration absorption and isolation support adopts smart casting parts, anti seismic efficiency is improved greatly, can effectively overcome press on the engineering have good endurance, supporting capacity height, size little, bend the problem that the back displacement is big, bend the suitable high comprehensive performance antidetonation shock attenuation bearing of back rigidity, can satisfy the demand that the shockproof requirements bridge is arranged.
The utility model is to adopt following technical scheme to solve:
Described universal ball foundry goods vibration absorption and isolation support mainly comprises upper base plate, middle seat board, following seat board, slide plate; Be inlaid with the tetrafluoro slide plate on the concave spherical surface of the upper base plate of described bearing, the top and bottom of described middle seat board are respectively equipped with sphere stainless steel slide plate, and described sphere stainless steel slide plate pastes in middle seat board external surface welding, is inlaid with the tetrafluoro slide plate on the concave spherical surface of described seat board down; The described upper base plate concave spherical surface outside is by the fixedly connected spacing ring of shearing bolt; Seat board is arranged between the concave spherical surface of the concave spherical surface of upper base plate and following seat board in described.
Described universal ball foundry goods vibration absorption and isolation support, described middle seat board is made of upper and lower two halfbodies, and described upper semi-body is a seat board in the top-surface camber, and described lower semi-body is a seat board in the lower surface camber; The bottom surfaces of seat board middle part is provided with pit in top-surface camber, and the upper side of seat board middle part is provided with projection in lower surface camber.
Described universal ball foundry goods vibration absorption and isolation support, described pit diameter is greater than projection.
Described universal ball foundry goods vibration absorption and isolation support, the concave spherical surface of described upper base plate, following seat board is the long radius sphere.
Described universal ball foundry goods vibration absorption and isolation support, described tetrafluoro slide plate are the filled polytetrafluoroethylene composite sandwich plate that burst is inlayed.
Described universal ball foundry goods vibration absorption and isolation support, the middle seat board periphery between described upper base plate and the following seat board is provided with the dust seal rubber ring.
Described universal ball foundry goods vibration absorption and isolation support is provided with the spring reinforcing bar in the described dust seal rubber ring.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
Described universal ball foundry goods vibration absorption and isolation support can play the effect of common bearing on the one hand, is about to the bridge upper load and passes to substructure equably, absorbs superstructure simultaneously because of creeping and caused telescopic displacement of variations in temperature and rotation; Can play on the other hand and subtract function of shock insulation, promptly when earthquake takes place,, reduce or isolate the influence of earthquake bridge or structure by special device; The utility model is divided into upper and lower two halfbodies with middle seat board, and when the shear wave of seismic wave and compressional wave alternately occurred, especially compressional wave can be dissolved compressional wave with the displacement of projection by the pit of two halfbodies; Characteristics of the present utility model are: agent structure adopts the smart casting of high-quality steel, and simple in structure, the antidetonation principle is clear and definite, does not contain easily aging materials such as rubber, good endurance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, shearing bolt; 2, spacing ring; 3, dust seal rubber ring; 4, upper base plate; 5, seat board in the top-surface camber; 6, pit; 7, projection; 8, seat board in the lower surface camber; 9, sphere stainless steel slide plate; 10, tetrafluoro slide plate; 11, following seat board; 12, spring reinforcing bar.
The specific embodiment:
Described universal ball foundry goods vibration absorption and isolation support is on the basis of common spherical bearing, replaces the planar friction pair with long radius sphere friction pair, and dissolves the shock wave that all directions focus is brought by the slidably local detachment in the seat board spheroid in being arranged on.
As shown in fig. 1, described universal ball foundry goods vibration absorption and isolation support mainly comprises upper base plate 4, middle seat board, following seat board 11, slide plate; Be inlaid with tetrafluoro slide plate 10 on the concave spherical surface of the upper base plate 4 of described bearing, the top and bottom of seat board are respectively equipped with sphere stainless steel slide plate 9 in described, described sphere stainless steel slide plate 9 pastes in middle seat board external surface welding, is inlaid with tetrafluoro slide plate 10 on the concave spherical surface of described seat board 11 down; The described upper base plate 4 concave spherical surfaces outside is by shearing bolt 1 fixedly connected spacing ring 2; Seat board is arranged between the concave spherical surface of the concave spherical surface of upper base plate 4 and following seat board 11 in described.
Described universal ball foundry goods vibration absorption and isolation support, described middle seat board is made of upper and lower two halfbodies, and described upper semi-body is a seat board 5 in the top-surface camber, and described lower semi-body is a seat board 5 in the lower surface camber; The bottom surfaces of seat board 5 middle part is provided with pit 6 in top-surface camber, and the upper side of seat board 5 middle part is provided with projection 7 in lower surface camber; Described pit 6 diameters are greater than projection 7; The concave spherical surface of described upper base plate 4, following seat board 11 is the long radius sphere; The filled polytetrafluoroethylene composite sandwich plate that described tetrafluoro slide plate 10 is inlayed for burst; Middle seat board periphery between described upper base plate 4 and the following seat board 10 is provided with dust seal rubber ring 3; Be provided with spring reinforcing bar 12 in the described dust seal rubber ring 3.
The shock insulation principle that subtracts of universal ball foundry goods vibration absorption and isolation support described in the utility model is, when earthquake generation and lateral force surpass set-point, shearing bolt is cut off, the cross spacing constraint of bearing is disengaged, long radius sphere friction pair laterally can be free to slide, thereby the kinetic energy that earthquake is produced is converted to potential energy.Simultaneously, in slipping, frictional resistance consumes a part of earthquake energy again; Two parts up and down of seat board can play repeatedly damping in when the earthquake energy is attacked once more.Like this, reach the effect of damping, prolonged earthquake period; And potential energy can form restoring force, and bearing is resetted, and damages and can change or adjust as bearing.
