Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment for operating turnouts or line breakers, in particular to a switch machine with an antifreeze function. Background Art

[0002] The switch machine is a switching device for turnouts. The switch machine is used beside the train track to switch turnouts, lock turnouts and reflect the position of the turnout point rail. Today, railways are spread all over the place. Beside the railways in high-altitude and cold areas, the cold weather and snow cover the switch machines. After a long time, the accumulated snow will freeze on the switch machines, which will affect the operation of the switch machines.

[0003] In order to ensure the normal operation of the switch machine, a snow melting device will be installed on the switch machine, and the snow covering its surface will be melted by the snow melting device to prevent the switch machine from being affected by the snow. However, the melted snow water may penetrate into the interior of the switch machine through the gaps of the switch machine, and then freeze the internal structure of the switch machine, thereby affecting the operation of the internal parts of the switch machine. In order to make it work normally, workers are required to de-ice the interior, which makes the switch machine more troublesome to use. Utility Model Content
