Description

Technical Field

[0001] The utility model relates to the field of railway snow melting equipment, and more specifically to a high-frequency electromagnetic automatic snow melting device for railway switches. Background Art

[0002] A railway turnout is a line connection device that allows locomotives and vehicles to switch from one track to another. It is also one of the weak links in the track. When it snows, the snow on the railway turnouts located in the northern region will quickly freeze and form a hard covering, which increases the difficulty of turning the turnout. If the snow is not melted in time, the turnout rotation will be blocked, making it impossible for the train to switch smoothly to the correct track, thus affecting the normal operation of the train. Therefore, a high-frequency electromagnetic and automatic snow-melting device will be installed at the turnout to ensure the safe travel of the train.

[0003] However, the existing automatic snow melting device is usually installed with fasteners such as bolts when laying railway turnouts, and the installation process is relatively complicated. In addition, when dismantling the device in non-severe cold seasons, the fasteners need to be removed one by one to complete the disassembly, which has low work efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a high-frequency electromagnetic automatic snow-melting device for railway turnouts to solve the problems existing in the above-mentioned background technology.

[0010] Furthermore, the rack and the teeth are meshed with each other, and the distribution area of the teeth outside the rotating shaft accounts for one quarter of the circumference of the rotating shaft.
