Description
Technical field
The utility model relates to the bridge technology field, particularly a kind of spherical bearing that is used for bridge.
Background technology
Along with the extensive use of spherical bearing on bridges such as highway in China, railway; bridge at earthquake-prone region requires to have fortification against earthquakes; bridge pad has anti-seismic performance; can bear the earthquake of bigger degree of splitting; thereby protect the safety of bridge more effectively; therefore we should design a kind of bearing that has anti-fall beam function when earthquake, to reach the recoverable purpose of earthquake back rest body.At present to bear the structure that bearing adopts be to be arranged on the periphery of bearing with bearing device to China's major part, and when the beam body produced pulling force, these bore device and can avoid the beam body to break away from.Because bearing also has rotating function, the structural shape that periphery bears has not only limited the flexible rotation of bearing, and when the rotation rear support bears pulling force, these bear structure and can not closely contact, have only local pressure, or even the line contact is stressed, this safe handling to bearing is totally unfavorable, gently then bearing distortion, heavy then to bear device entirely ineffective.Therefore we should design a kind of novel bearing and avoid above problem.
The utility model content
The purpose of this utility model is the deficiency that overcomes existing spherical bearing, the spherical bearing that provides a kind of centre to bear.
The technical solution of the utility model is: the spherical bearing that a kind of centre bears, comprise upper base plate, bulb flat, tension block and following seat board, it is characterized in that described upper base plate is arranged on topmost, be placed with Ball faced nut, aligning slide block, bulb flat and following seat board successively and draw screw rod to fix below the upper base plate by leading; Be provided with tension sphere tetrafluoro slide plate between described Ball faced nut and the aligning slide block, described tension block upper end is fixed on the bottom surface around the upper base plate, contiguous bulb flat of its medial surface and following seat board.
The block of tension described in the utility model upper surface is to adopt screw rod to be fixed on the upper base plate, is provided with tetrafluoro slide plate I between tension block and the bulb flat, is provided with tetrafluoro slide plate II between tension block and the following seat board.
Be fixed with pressure-bearing plane tetrafluoro slide plate between two ends end face of bulb flat described in the utility model and the upper base plate, be provided with pressure-bearing sphere tetrafluoro slide plate between bottom surface and the following seat board, in be provided with between intracardiac diapire and the aligning slide block and be subjected to surface broaching tetrafluoro slide plate.Pressure-bearing plane tetrafluoro slide plate is embedded on the bulb flat.
The center that above-mentioned master draws screw rod to pass Ball faced nut, aligning slide block, bulb flat and following seat board is fixed and is in the same place.Described Ball faced nut and aligning slide block are arranged in the bulb flat.
The utility model is a kind of based on the universal serial spherical bearing, and sets up the novel bearing of puller system thereon.It is except that functions such as the pressure-bearing that the universal serial spherical bearing is arranged, rotation, displacement, alleviate effects such as vertical pulling force that beam-ends counterweight and opposing produce because of centrifugal force, transverse rocking force, transverse wind and waves of seawater power etc. and cross shear in addition, can also solve problems such as beam reliably, make the stressed and displacement of beam body more stable, thereby prolong the application life of bridge.

Fig. 1 is that the utility model partly cuts open structural representation
Among the figure: 1-tension sphere tetrafluoro slide plate; The 2-Ball faced nut; The 3-upper base plate; 4-pressure-bearing plane tetrafluoro slide plate; The 5-bulb flat; 6-tetrafluoro slide plate I; 7-tension block; 8-aligning slide block; 9-tetrafluoro slide plate II; 10-is subjected to surface broaching tetrafluoro slide plate; 11-pressure-bearing sphere tetrafluoro slide plate; Seat board under the 12-; 13-master draws screw rod.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further as shown in Figure 1: the spherical bearing that the centre bears comprises upper base plate 3, bulb flat 5, tension block 7 and following seat board 12.Seat board 3 is arranged on topmost, be placed with Ball faced nut 2, aligning slide block 8, bulb flat 5 and following seat board 12 and fixing by the main screw rod 13 that draws below the upper base plate 3 successively, the main screw rod 13 that draws is that the center of passing Ball faced nut 2, aligning slide block 8, bulb flat 5 and following seat board 12 is fixed and is in the same place.
Be fixed with pressure-bearing plane tetrafluoro slide plate 4 between bulb flat 5 two ends end faces and the upper base plate 3, be provided with pressure-bearing sphere tetrafluoro slide plate 11 between bottom surface and the following seat board 12, in be provided with between intracardiac diapire and the aligning slide block 8 and be subjected to surface broaching tetrafluoro slide plate 10.Ball faced nut 2 and aligning slide block 8 are arranged in the bulb flat 5.
Be provided with tension sphere tetrafluoro slide plate 1 between described Ball faced nut 2 and the aligning slide block 8, described tension block 7 upper ends adopt screw rod to be fixed on upper base plate 3 bottom surface all around, the contiguous bulb flat 5 of its medial surface and following seat board 12.Be provided with tetrafluoro slide plate I 6 between tension block 7 and the bulb flat 5, be provided with tetrafluoro slide plate II 9 between tension block 7 and the following seat board 12.
The utility model operating principle is as follows: cooperate the horizontal movement that realizes bearing by upper base plate 3 with pressure-bearing plane tetrafluoro slide plate 4 on being embedded in bulb flat 5; Realize the longitudinally guiding and the anti-cross shear of bearing by the tetrafluoro slide plate II 9 on tension block 7 and following seat board 12 both sides; By seat board 12, master draw screw rod 13, Ball faced nut 2, aligning slide block 8, bulb flat 5, tension block 7 and upper base plate 3 to realize the anti-vertical pulling force of bearing down; Satisfy the corner requirement of bearing by the rotation between the rotation between Ball faced nut 2 and the aligning slide block 8 and bulb flat 5 and the following seat board 12.
The utility model passes through tensile device; vertical pulling force and cross shear that beam-ends counterweight and opposing produce because of centrifugal force, transverse rocking force, transverse wind and waves of seawater power etc. have been alleviated; can solve problems such as beam reliably, bridge is played effective protective effect.Pressure-bearing and tension the necking of power do not occur evenly by the sphere power transmission, and power transmission is steady, and the counter-force that acts on the concrete is more even.Tensile device still can satisfy the rotating property requirement thereby guaranteed to install under tension state, and rotating torque is little by the sphere power transmission.Device is specially adapted to wide bridge, overpass bridge, curved bridge, cable stayed bridge, suspension bridge and long-span bridge respectively to the rotating property unanimity.
