Railway tunnel vault deicing device

Abstract

The invention provides a railway tunnel vault deicing device, and relates to the technical field of railway transportation. The railway tunnel vault deicing device comprises connecting parts, slidingdevices, deicing mechanisms, ice melting mechanisms and rolling wheels; the ice melting mechanisms are arranged at the top ends and the bottom ends of the connecting parts, cleaned broken ice is melted through the ice melting mechanisms, and the ice melting mechanisms are fixedly connected with the top ends and the bottom ends of the connecting parts; the deicing mechanisms are arranged between the connecting parts, and the deicing mechanisms are used for removing ice columns on a vault and ice on the surface of the vault; the left end and the right end of each deicing mechanism are fixedly connected with the corresponding connecting part; sliding devices are arranged at the bottom ends of the deicing mechanism so that the deicing mechanisms can be conveniently attached to the vault to remove ice; and the top ends of the sliding devices are in sliding connection with the top ends of the deicing mechanisms, the rolling wheels are arranged at the bottom ends of the sliding devices, and the rolling wheels penetrate through the bottom ends of the sliding devices to be rotationally connected with the bottom ends of the sliding devices. The problem that ice on the surface of the vault cannot be removed when the vault is deiced so as to cause secondary icing easily is solved.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a deicing device for a railway tunnel vault. Background technique [0002] The railway tunnel is a channel specially used for train transportation. When the railway passes through the mountainous area, due to the limited traction capacity and the maximum slope requirement, it is necessary to overcome the elevation obstacle. Excavating a tunnel to cross the mountain is a reasonable choice. Its function is to shorten the line and reduce the Small slopes improve operating conditions and increase traction capacity. [0003] There will be gaps between the arches on the inner wall of the vault of the railway tunnel. In cold places in winter, icicles will form on the inner wall of the tunnel vault. As the area of ​​ice gradually increases, the moisture seeping from the vault It may fall on the rails and cause the rails to freeze, thereby affecting the normal running of t...
