Problems solved by technology
[0005] 1. The ring structure is adopted as a whole, and only one position is used for shock absorption, because when the stay cable vibrates, it is often transmitted by waveform vibration, and the effect of shock absorption is poor;
[0006] 2. The device only uses steel balls to offset the vibration, the effect is poor, and it is prone to environmental corrosion

The invention relates to the technical field of engineering structure vibration reduction, in particular to a new ring-shaped damper for suppressing the vibration of bridge stay cables, including two sets of symmetrically arranged fixing parts, and two symmetrically arranged damping shock absorbers in the semicircle-arc block Assemblies, the two sets of fixing parts are connected by a number of connecting shock-absorbing components arranged around them, the outer casing of the two sets of fixing parts is provided with a cylindrical pleated protective layer, and both ends of the cylindrical pleated protective layer are provided with round holes connecting the inside, two U The type fixing strips are all provided with some second installation waist holes. The present invention adopts the method of viscous bonding of the damping and shock-absorbing components to achieve the purpose of viscous damping and shock-absorbing, and cooperates with a number of steel balls arranged inside to play a shock-absorbing effect on the fixed position of the fixing parts. The space is connected by a damping shock-absorbing column, and a damping rubber column is also provided to assist in weakening the wavy vibration. The device also has the functions of easy disassembly and self-protection.
Description
technical field [0001] The invention relates to the technical field of engineering structure vibration reduction, in particular to an annular damper for suppressing the vibration of bridge stay cables. Background technique [0002] A cable-stayed bridge, also known as a cable-stayed bridge, is a bridge in which the main girder is directly pulled on the bridge tower by many cables, and is mainly composed of a cable tower, a main beam, and cable-stayed cables. The main load-bearing component is the cable-stayed cable. Because the length of the current cable-stayed bridge is getting longer and longer, the length-to-diameter ratio of the cable-stayed cable as the main load-bearing component increases accordingly, and the vibration of the cable-stayed cable is prone to occur, resulting in the connection position The firmness is reduced, causing adverse effects. At present, the damping shock absorbers fixed on the bridge deck are often connected to the stay cables for vibration r...
