Description

Technical Field

[0001] The utility model belongs to the technical field of rail vehicles, and more specifically relates to a heating device for removing a floor cloth of an EMU. Background Art

[0002] During advanced repairs on EMU trains, the complete removal of the floor coverings is necessary. These coverings are primarily adhered to the wooden floor panels with neoprene adhesive. However, the neoprene adhesive can only be softened and completely removed by heating it to 80-100°C. Currently, heat shrink guns are the preferred tool for removing floor coverings. During this process, the operator must first adjust the heat shrink gun to the melting point of the neoprene adhesive, then use one hand to hold the gun and the other to remove the floor covering, which has reached the melting point. This method of operation can easily cause uneven heating of the floor covering, affecting the quality of the removal. Furthermore, the operator's operating environment is poor, resulting in low efficiency. Utility Model Content
