As the ice accumulates on the top of the tunnel, the railway outflow collides with the ice when passing through, thus threatening the safety of train driving. At this time, an ice melting device is needed to remove the ice on the inside of the tunnel to ensure the safe operation of the train.

[0026] Working principle: The inner side of railway tunnels located in high-cold areas is prone to condensation of ice in cold seasons. As ice accumulates on the top of the tunnel, the railway outflow collides with the ice when passing through, thus threatening the driving safety of the train. At this time, an ice melting device is needed to remove the ice inside the tunnel to ensure the safe operation of the train. The existing ice melting device uses an electric heating film and can only remove a thin layer of ice. In tunnels in high-cold areas, icicles are easily condensed, and the ice melting device cannot remove them at this time. In order to solve this problem, a de-icing mechanism and a lifting mechanism are set to control the hydraulic cylinder 11 to extend the inner hydraulic rod 12, thereby pushing the support rod 2 to slide up and down in the inner slide groove 10 of the bracket 1, thereby moving the support rod 2 to a suitable height.

After the heating wire 4 contacts with the condensed ice, the root of the ice is melted, so that it falls from the top side of the tunnel to the ground and breaks into small pieces. At the same time, the heat of the heating wire 4 is transferred to the metal plate 7 through the heat conducting plate 6. The metal plate 7 contacts with the remaining ice and melts it to achieve the function of deicing. In addition, this structure can be applied to ice of any size, solving the problem that the existing ice melting device cannot remove large ice.
