Intelligent supporting device for municipal large-span bridge building

Abstract

The invention discloses an intelligent supporting device for a municipal large-span bridge building. The wind speed on a bridge floor is detected in real time through a wind speed meter, a signal is transmitted into a reinforcing controller through a transmission wire and a signal transmitter, after analysis of the reinforcing controller, if the wind power is large, a tensioning hydraulic cylinder is started, a bridge body is tensioned downwards through a vertical iron chain and a connecting ring, so that the phenomenon that traffic safety is affected by vortex vibration is prevented, a buffer sleeve, a rotating sleeve and the like are arranged, a cement bridge pier can be protected to a certain degree, the situation that cement falls off due to the fact that water flow surges continuously impact the surface of the bridge pier is avoided, and as a pressure sensor and the like are arranged, a supporting telescopic rod drives an auxiliary top plate to jack up the bridge body, thereby achieving the purpose of strengthening and supporting; when the traffic flow is small, the flow controller controls the supporting telescopic rod to contract, so that the bridge body has certain toughness, and the purpose of intelligent supporting is achieved.

Description

technical field [0001] The invention relates to the field of bridge support, in particular to an intelligent support device for a municipal long-span bridge building. Background technique [0002] In fluid dynamics, vortex-induced vibration is the motion induced on the object itself by the interaction between the object and the external fluid, or the periodic irregular motion generated on the fluid. Since real fluids always have a certain viscosity, when in contact with the surface of a cylinder, the fluid flow around the cylinder will slow down, forming a so-called boundary layer. However, at a certain point, due to the excessive curvature of the cylinder, the boundary layer may separate from the object and then form eddies that change the pressure distribution along the surface of the cylinder. When a vortex is not formed symmetrically around an object (relative to its mid-plane), different lift forces are generated on each side of the object, resulting in motion transver...
