Abstract

The utility model relates to a bridge shock absorber, which is arranged at the root of a bridge cable of a cable-stayed bridge for realizing the shock absorbing effect. The shock absorber comprises a metal ring (1) and a rubber ring (2), wherein the metal ring (1) is formed by combining a left half metal ring (11) and a right half metal ring (12) at the left side and the right side, the rubber ring (2) is formed by combining a left half rubber ring (21) and a right half rubber ring (22) at the left side and the right side, a circle of groove (13) is arranged on the inner wall surface of the metal ring (1), a matched flange (23) matched with the groove (13) is arranged in a corresponding position on the outer wall surface of the rubber ring (2) relatively to the groove (13), the rubber ring (2) is compounded on the inner ring of the metal ring (1), and in addition, the flange (23) is embedded in the groove (13). Through installing the bridge shock absorber of the utility model at the root of the cable, the resonance frequency of the cable can be changed, the vibration amplitude is controlled, the vibration wave transmission is inhabited, the material fatigue is reduced, the influence on the cable-stayed bridge caused by factors such as wind power, vehicle vibration and the like can be relieved, and the service life of the cable is prolonged.

Description

The bridge damper
(1) technical field
The utility model relates to a kind of damping device.Be arranged at the bridge cable root of drag-line bridge, play cushioning effect.Belong to the damper technical field.
(2) background technology
The bridge cable root of traditional drag-line bridge is not owing to there being damping device, so the drag-line bridge is because the factor affecting such as vibrations that wind-force and vehicle produce have caused reduce the application life of drag-line.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of bridge damper that can alleviate the factor affecting such as vibrations of wind-force and vehicle generation is provided.
The purpose of this utility model is achieved in that a kind of bridge damper, comprise quoit and rubber ring, described quoit is by left semimetal circle and the right semimetal circle left and right sides is involutory constitutes, rubber ring is by a left side half rubber ring and right half the rubber ring left and right sides is involutory constitutes, on the quoit internal face, be provided with a circle groove, corresponding to this groove, the corresponding position is provided with a flange with matching on described rubber ring outside wall surface; Described rubber ring is compound in the quoit inner ring, and described flange is embedded in the described groove.
The beneficial effects of the utility model are:
By the utility model bridge damper being installed, can change the resonance frequency of drag-line, the control amplitude at the root of drag-line, suppress the vibration wave propagation, reduce the fatigue of material, alleviated the factor affecting such as vibrations of drag-line bridge, the application life of having improved drag-line owing to wind-force and vehicle generation.
