Abstract
Overhead bridge support damping device, the utility model relates to a bridge construction field, overhead bridge support damping device includes the base, spring assembly, and strutting arrangement triplex, the formula of cutting bracing piece is at first imported into through last base to the vibrations of bridge floor, cut formula bracing piece pressurized and do folding motion downwards, lead to the pulley to produce the displacement in the pulley groove, the pulley has driven two spring fixed plates and has produced displacement dorsad, the pulling force of displacement production transmits the connecting plate dorsad, on connecting bolt and the spring, the spring has stronger weakening effect to the axial tension, consequently, this device has just reached bridge absorbing mesh. The utility model discloses a spacing slide bar can protect the spring part to avoid its elastic recovery intensity that exceedes self effectively, spring structure shock attenuation mode, the environmental protection is and the use keeps the shock attenuation effect lastingly, and the structure is more reliable.
Description
Technical field
The utility model relates to bridge construction field, specifically refers to elevated bridge bearing damping device.
Technical background
In bridge construction field, damping device is important component part, common Bridge Seismic method is mostly by using chemical industry method synthesis beam to make bridge reach the object of damping, this shock-dampening method materials processing use procedure not environmentally, and functional performance presents falling tendency along with the increase of service time, work unreliable, be therefore badly in need of a kind of novel bridge damping device and solve this problem.
Utility model content
In order to the utility model that solves the problem provides a kind of elevated bridge bearing damping device, can solve existing highway bridge shock-dampening method not environmentally, and functional performance presents falling tendency along with the increase of service time, work insecure problem.
Technical solutions of the utility model: elevated bridge bearing damping device, described elevated bridge bearing damping device comprises base, spring assembly and bracing or strutting arrangement three part,
Described base comprises upper bed-plate and lower bottom base, and upper bed-plate and lower bottom base are provided with pulley groove.
Described bracing or strutting arrangement comprises pulley, scissors support bar, spacing slide bar, scissors support bar two ends are respectively equipped with pulley, pulley slidably reciprocates in the pulley groove of upper bed-plate and lower bottom base, and spacing slide bar 2 is arranged on scissors support bar, can limit the support amplitude of scissors support bar.
Described spring assembly comprises junction plate, connecting bolt, spring, spring dead plate, the two ends of described spring are fixed on junction plate by connecting bolt, junction plate is fixed on two pieces of spring dead plates, each group junction plate, connecting bolt, spring form a spring assembly, and two pieces of spring dead plates are connected on pulley.
Described elevated bridge bearing damping device comprises four spring assemblies.
The beneficial effects of the utility model:
1, the utility model adopts spacing slide bar can effectively protect spring part to avoid it to exceed the elastic recovery intensity of self.
2, the utility model adopts spring structure damping modes, environmental protection and use and keep damping effect lastingly, and structure is more reliable.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is part-structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, Fig. 2 example, the utility model is described in further detail.
The technical solution adopted in the utility model is: elevated bridge bearing damping device, and described elevated bridge bearing damping device comprises base, spring assembly and bracing or strutting arrangement three part,
