Problems solved by technology

[0003] However, damping bearings, which are widely used in the field of bridge technology at this stage, have low energy dissipation capacity for horizontal loads. When the horizontal displacement is large, it will cause serious damage to the damping bearings and make their capabilities invalid.

[0016] Specific implementation mode one: as Figure 1~Figure 8 As shown, the present invention discloses a bridge damping bearing, comprising a base 1, a top plate 2 and two damping devices, the upper surface of the base 1 is provided with a chute 1-1 along the length direction, and the chute 1 Both ends of -1 are vertically provided with baffles 1-2, the base 1 and the two baffles 1-2 are U-shaped and integrated, and the middle positions of the two baffles 1-2 are respectively provided with Perforation 1-3, installation grooves 1-4 are recessed in the middle of the upper end surfaces of the two baffles 1-2 along the width direction, the top plate 2 is horizontally arranged above the base 1, and the bottom of the top plate 2 is integrally connected by the vertical plate 2-1 There is a slider 2-2, and the slider 2-2 is slidably connected to the middle section of the chute 1-1, the chute 1-1 is preferably an inverted T-shaped structure, and the slider 2-2 is matched with the chu...

specific Embodiment approach 2

[0017] Specific implementation mode two: as Image 6 , 7 , 8, this embodiment is a further description of specific embodiment 1, the two ends of the sun gear 3-1 are respectively provided with a gap between the inner surface of the corresponding circular plate 4-2, and the two sides of the sun gear 3-1 The end faces are respectively coaxially recessed with an annular groove 1 3-6, and the inner surface of the circular plate 4-2 is coaxially recessed with an annular groove 2 4-4, the annular groove 1 3-6 and the annular groove 2 4-4 Oppositely fit with a group of balls 7 sandwiched between them.

specific Embodiment approach 3

[0018] Specific implementation mode three: as figure 2 , 5 As shown, this embodiment is a further description of the specific embodiment 1. The length of each screw lever 5 is sufficient. When the top plate 2 slides to the two ends of the base 1 along the chute 1-1, The two wire levers 5 are not disengaged from the corresponding sun gear 3-1.

[0019] The present invention is installed between the beam body and the bridge pier when in use, the base 1 is fixed to the upper surface of the bridge pier, and the top plate 2 is fixed to the lower surface of the beam body. Generally, it is arranged vertically according to the bridge. The principle is: when the beam body is subjected to horizontal When the load generates the longitudinal displacement of the bridge, the top plate 2 fixed to the beam body moves relative to the base 1 along the chute 1-1, and the two screw levers 5 cooperate with the two planetary gear mechanisms 3 to convert the linear motion into rotation movement, ...

Abstract

The invention provides a damping support used for a bridge and relates to a bridge support. A sliding groove is formed in the upper surface of a base, and baffles are arranged at the two ends of the base. Penetrating holes are formed in the baffles. Installation grooves are recessed in the upper end faces of the baffles. A top board is in sliding connection with the middle section of the sliding groove. Each damping device comprises a planet gear mechanism, a damping shell and a screw lever. The damping shells are fixedly connected with the installation grooves. Each planet gear mechanism is coaxially arranged in the corresponding damping shell. Each planet gear is fixed between two round boards of the corresponding damping shell through a locating shaft. Viscous liquid is filled between each gear ring and the outer ring of the corresponding damping shell. Sealing rings are embedded and fixed into the inner surfaces of the round boards. The center holes of sun gears are threaded holes.Through holes are formed in the centers of the round boards. The middle sections of the screw levers are in threaded fit with the threaded holes. The inner side ends of the screw levers are connectedwith the top board to be fixed. The damping support has the extremely high horizontal load energy dissipation capacity and can adapt to large horizontal displacement, and structural effectiveness isimproved.

Description

technical field [0001] The invention relates to a bridge support, in particular to a bridge damping support. Background technique [0002] In order to avoid large damage to bridges caused by external forces such as earthquake disasters, anti-seismic measures must be taken during bridge construction. However, the traditional way of relying on strengthening the structure to improve the anti-seismic capacity has been proved by many facts to be difficult to achieve a good anti-seismic effect, and may even amplify the earthquake. The effect has been gradually eliminated. At present, damping bearings capable of energy dissipation and shock absorption are usually installed between the beam body and the bridge pier, and the damage to the structure caused by the earthquake force is reduced through energy dissipation and shock absorption technology. [0003] However, damping bearings, which are widely used in the field of bridge technology at this stage, have low energy dissipation ca...
