A multifunctional adjustable bridge electromagnetic damper and bridge

Abstract

The invention relates to a multi-functional adjustable bridge electromagnetic damper and bridge, which comprises: a cylinder body, a fixed electromagnetic head is arranged in the cylinder body; a piston rod, which has a first end pierced in the cylinder body ; By controlling the magnetic pole of the fixed electromagnetic head to be opposite or the same as the magnetic pole of the first end, the cylinder body and the piston rod are locked or unlocked. The invention relates to a multifunctional adjustable bridge electromagnetic damper and the bridge, which can be used in various states of the bridge, and the bridge does not need to be dismantled after the bridge is built, which saves the temporary consolidation device of the tower and girder during the construction of the cable-stayed bridge Resources, reduce construction procedures and links, speed up the progress of the project, facilitate centralized control of construction operations, and ensure construction quality and safety.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a multifunctional adjustable bridge electromagnetic damper and a bridge. Background technique [0002] A cable-stayed bridge is a bridge in which the deck system is under compression and the supporting system is under tension. The supporting system is composed of cables. Although the construction of cable-stayed bridges in my country started late, it has developed rapidly. The Shanghai Yangpu twin-tower space double-cable plane steel-concrete composite girder cable-stayed bridge built in 1993 has maintained a world-leading 602m main span record for 6 years. In 2008, the Sutong Yangtze River Bridge cable-stayed bridge has maintained a world-leading record with a main span of 1088m. Although the cable-stayed bridge has a large spanning capacity, its construction is also difficult, and the construction and use risks of the cable-stayed bridge are also high. Displacement, torsion, e...

Problems solved by technology

[0006] The embodiment of the present invention provides a multifunctional adjustable bridge electromagnetic damper and bridge to solve the problem that in the related art, the bridge temporary consolidation device is only used in the construction stage. After the main girder is closed, the temporary consolidation device is removed and discarded, which is a waste of resources. The problem
