In order to crush icicles generated at the top of an electric railroad tunnel due to deterioration and poor construction in winter in a tunnel in which a special high-voltage catenary line (including a joga line) is installed for electric railway operation, the upper part of the tunnel is in the longitudinal direction. It relates to a movable icicle crushing system for an electric railway tunnel comprising an installed guide means and a crushing moving means installed with a crushing means moving forward or backward in the longitudinal direction of the tunnel along the guide means, and more specifically, the guide The lower surface of the means is open to the means, and a duct shape in which inward bent portions are formed on both sides of the opened lower surface is formed long in the longitudinal direction of the tunnel above the tunnel, and a power supply copper plate, which is a conductor, is elongated in the longitudinal direction of the tunnel.

In recent years, electric railways operated by electricity are increasing, and in railways operated by such electric railways, catenary lines (including Joga Lines) are installed at the top along the railway to supply power to the electric railways. It is fixed and installed on a movable bracket (insulator) installed on the ceiling or upper side of the tunnel.

On the other hand, in old tunnels or poorly constructed tunnels, there is a partial leak from the ceiling, and even if repairs are made, the leak cannot be completely caught. This leakage phenomenon in the tunnel grows as icicles on the ceiling of the tunnel in winter, and when the icicle touches the catenary line, the catenary line is short-circuited and the power supply is tripped. This causes the electric rail to stop. Since safe operation cannot be guaranteed, a lot of manpower is being put into the field to remove icicles so as not to cause a short circuit of the catenary in winter, and when icicles are identified, icicles are removed by live line work. In this way, in order to remove icicles in winter, there is a problem that safety accidents frequently occur due to the need for cost due to the input of a large amount of manpower, and the removal of icicles during live wire work and electric railway operation.
