specific Embodiment approach 1
[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, ...
