Damping shock absorption mechanism for stay cable of bridge

Abstract

The invention discloses a damping shock absorption mechanism for a stay cable of a bridge, relates to the technical field of incubators, and solves the problems that an existing buffer device is onlyprovided with a group of buffer dampers, the buffer dampers are easy to lose effect due to the influence of fatigue strength in use, and once a stay cable mounting seat loses connection strength, thestability is poor. The top of a bridge floor is fixedly connected with a group of mounting bases; the top of each mounting base is connected with a group of supporting rods through hinges; the left side and the right side of the inhaul cable fixing base are each elastically connected with a set of buffer fixing base. The buffer fixing base and the inhaul cable fixing base are both fixed to the bridge stay cable at the same time. The two buffer dampers are used for buffering and absorbing vibration, the good vibration absorption capacity is guaranteed, the working stability is improved throughthe two buffer dampers, when the installation strength of the inhaul cable fixing base is not enough, buffering and vibration absorption can be conducted through the buffer base buffer springs, the working stability is guaranteed, and the bridge safety can be better guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a bridge stay cable damping shock absorbing mechanism. Background technique [0002] Cable-stayed bridge, also known as cable-stayed bridge, is a bridge in which the main girder is directly pulled on the bridge tower by many cables. The structural system can be regarded as a multi-span elastically supported continuous beam with cables instead of buttresses, which can reduce the bending moment in the beam body, reduce the height of the building, reduce the weight of the structure, and save materials. The cable-stayed bridge is mainly composed of cables It is composed of tower, main girder and stay cables, among which the stay cables of bridges are important load-bearing components. Due to their small mass, stiffness and damping, the stay cables of bridges are prone to vibration, especially when the pull cables are subjected to large vibrations under the combined action ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a bridge stay cable damping and shock absorbing mechanism to solve the problem that the existing buffer device proposed in the above background technology only has one set of buffer dampers, and the buffer dampers are easily lost due to the influence of fatigue strength during use. As a result, the cushioning effect cannot be well played. At the same time, the stay cable mounting base is directly installed with the stay cable. Once the stay cable mounting base loses its connection strength, the shock absorbing mechanism will lose its damping function, and the working stability will be unstable. good question
