Damper structure used for bridge stay cable and arranged along length of cable

Abstract

The invention relates to the technical field of civil engineering, in particular to a damper structure used for a bridge stay cable and arranged along the cable length. Openings are formed in edges ofan outer ring and an inner ring so that an inhaul cable can smoothly enter the center of the inner ring; the outer ring and the inner ring are connected through a damping buffer anda damping spring.Vibration generated by the inhaul cable fixed to the center of the inner ring in the vibration environment is decomposed, released, converted and absorbed under the action of the damping buffers and the damping springs, then the vibration reduction effect is achieved, the effects of rapid mounting and rapid dismounting are achieved on the whole, and vibration of the bridge inhaul cable is well reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a damper structure used for bridge stay cables and arranged along the cable length. Background technique [0002] With the continuous development and progress of bridge technology, the types of bridges are also constantly diversifying. In order to make bridge construction technology in our country safe and effective, new high requirements are constantly put forward for construction technology, and bridge construction technicians must also constantly master The structural strength of the bridge under construction, and the accurate calculation of the stability coefficient of the bridge. At the same time, the maintenance and supervision of the bridge after the bridge is built is also extremely important, because with the application of the built bridge in practice, it will encounter There are many problems, such as the aging of its own materials, the interference of extern...

AI Technical Summary

Problems solved by technology

[0004] At present, there are few or even no protection measures for the vibration of the cable in the existing technology, which is a kind of vibration generated by the cable itself when the cable encounters some wind and rain, external forces, etc., and this vibration lasts for a long time. It will have an adverse effect on the tensioning structure of the cable, connecting parts, etc., and if it is serious, it will affect the overall structure of the bridge and cause displacement and deformation.
