Electromagnetic induction deicing device and deicing method for bridge tower cross beam

Abstract

The electromagnetic induction deicing device comprises a control box and a heating module, the heating module comprises a shell, an electromagnetic heating plate and an electromagnetic induction coil, the shell is hung and fixed to the side face of the tower bridge cross beam, the electromagnetic heating plate and the electromagnetic induction coil are arranged on the outer side of the shell, and the electromagnetic heating plate covers the whole side face of the tower bridge cross beam; the electromagnetic induction coil is mounted in the shell through a transverse translation device; during operation, the electromagnetic induction deicing device is started, whether the windward side of the electromagnetic heating plate and the lower surface of the bridge tower cross beam are iced or not is monitored through the icing monitoring module, if yes, the heating module is started, a deicing state is entered, and if not, an anti-icing state is entered; determining whether to start the heating module according to the environment temperature; when the heating module is started, the electromagnetic induction coil is driven by the transverse translation device to move in the shell, and the electromagnetic heating plates in different areas are heated and deiced in a scanning mode. According to the invention, the cross beam can be deiced at the maximum efficiency at the minimum cost, and the operation safety requirement of a bridge in winter is met.

Description

technical field [0001] The invention belongs to the field of bridge construction and maintenance, and relates to a bridge deicing technology, in particular to an electromagnetic induction deicing device and a deicing method for bridge pylon beams. Background technique [0002] As an important part of traffic lines, bridges are of the utmost importance to ensure their safety in various environments. As the main bridge types of long-span bridges, cable-stayed bridges and suspension bridges have their presence everywhere. Often towering towers, long-span beams across the driveway have become the best identification signs. However, under the weather of low temperature, rain and snow, affected by the wind, it is easy to produce frost and icing on the sides of the bridge pylon beams. Accidental falling of ice will cause great safety hazards to vehicles and pedestrians on the bridge. In recent years, traffic accidents caused by ice falling on the beam of tower bridges are not unc...
