Description
Technical field
The utility model relates to cable way bridge antivibration area, specifically a kind of passive damper on cable way bridge, bestirs oneself with the wind vibration response of lower bridge floor for reducing wind.
Background technology
Cable way bridge, as a kind of type of bridge, has a wide range of applications at present in temporary construction suspension bridge and mountain area Simple bridge etc.Cable way bridge is made up of main rope, anchoringwire, tail rope, wind cable, gooseneck and bridge deck, and belong to flexible structure, natural vibration period is long.When wind vibration frequency and cable way bridge intrinsic frequency close to time, cable way bridge resonates, and has a strong impact on the use of cable way bridge, even injures the safety of cable way bridge.
Cable way bridge generally by pull wind rope come restraint rope bridge wind carry effect under displacement.This method is not considered to comprise the vibration of overall structure under wind shakes of pulling wind rope, and it is less for the vertical displacement restriction under load of shaking of cable way bridge wind to pull wind rope.
Therefore, exploitation is a kind of considers bridge overall structure frequency, increases structural damping, the simply constructed damper of easy construction, for restraint rope bridge wind bestir oneself with under down wind and vertical displacement, reduce wind vibration response, ensure safe important in inhibiting before cableway.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of passive damper on cable way bridge, for increasing the damping of cable way bridge, reduces the vibration of cable way bridge under wind bestirs oneself use, safety before guarantee cableway.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A passive damper on cable way bridge, comprises damping spring, casing, and described casing is connected with cable way bridge gooseneck, and the center of casing is provided with mass, and mass is fastened on the tank wall of casing by damping spring.
Adopt the utility model of technique scheme, its beneficial effect is:
Damper is directly fixed on cable way bridge gooseneck by its casing, connects reliably easy, constructability; The maximum position of cable way bridge vibratory response is span centre, and damper can effectively reduce its vibratory response in cable way bridge span centre; Cable way bridge is under wind shakes load, bridge longitudinal restraint is stronger, vertical and more weak perpendicular to cable way bridge longitudinal restraint, vibratory response is larger, the displacement of the above-mentioned both direction of damping spring constraint mass, namely damper provides the damping of this both direction, effectively can reduce the vibration that cable way bridge wind shakes under load; This passive damper structure is simple, easy construction, can the safety of effective guarantee cable way bridge and normally use.
As preferably, the utility model further technical scheme is:
Casing is square, and mass is spheroid or square, and one end of damping spring is directly fixed on casing; The other end of damping spring is affixed on mass, the line intersecting vertical of damping spring.Casing can be cast by metal sheet, rolling or be welded.The casing of square, damping spring is symmetrical set, easy for installation, and damping is good.
A side of described casing is connected with cable way bridge gooseneck, and other three sides of casing are provided with floor of putting more energy into.The wall box of square is surface plate, and the side-wall outer side of fixing damping spring welds floor of putting more energy into, and prevents sidewall cripling.
Described floor of putting more energy into is cuboid, and floor of putting more energy into is arranged on the lateral surface of casing tank wall.Put more energy into floor just to damping spring, is fixed on the lateral surface of casing tank wall, can effectively prevent sidewall cripling.
Described damping spring is steel damping spring or rubber damping spring.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Composition graphs 1-Fig. 4 is known, and a kind of passive damper on cable way bridge, is made up of damping spring 3, casing 1, and the center of casing 1 is provided with mass 2, and mass 2 is fastened on the tank wall of casing 1 by damping spring 3.
Casing 1 is square, and mass 2 is spheroid or square, and one end of damping spring 3 is directly fixed on casing 1; The other end of damping spring 3 is affixed on mass 2, the line intersecting vertical of damping spring 3.Casing 1 can be cast by metal sheet, rolling or be welded.The casing 1 of square, damping spring 3 is symmetrical set, easy for installation, and damping is good.A side of casing 1 is connected with cable way bridge gooseneck, and other three sides of casing 1 are provided with floor 5 of putting more energy into.Casing 1 sidewall of square is surface plate, and the side-wall outer side of fixing damping spring 3 welds floor 5 of putting more energy into, and prevents sidewall cripling.
Put more energy into floor 5 for cuboid, and floor 5 of putting more energy into is arranged on the lateral surface of casing 1 tank wall.Put more energy into floor 5 just to damping spring 3, is fixed on the lateral surface of casing 1 tank wall, can effectively prevent sidewall cripling.
Damping spring 3 is steel damping spring or rubber damping spring.
Casing 1 directly and cable way bridge gooseneck weld together, gooseneck end face, bottom surface and side can be welded on depending on concrete bridge floor layout; Casing 1 can be chosen as square, loads damping spring 3 and mass 2 in casing 1; Damping spring 3 one end is connected to mass 2, and the other end is fixed on casing 1 wall containing floor 5 of putting more energy into.Translational degree of freedom vertically with perpendicular to cable way bridge longitudinal direction is retrained by damping spring 3, and other translational degree of freedom and rotational freedom are retrained by casing 1 wall; Therefore the technical program can increase the damping of cable way bridge, reduce the vibration of cable way bridge under wind bestirs oneself use, safety before guarantee cableway.
Owing to the foregoing is only the detailed description of the invention of this invention, but protection of the present invention is not limited thereto, and any those skilled in the art can expect the equivalent change of the technical program technical characteristic or substitute, and are all encompassed within protection scope of the present invention.
