[0002] With the dual improvement of railway transportation technology and running speed, the traffic density of conventional railway passenger trains and freight trains has increased, and the train travel scheduling time has become more and more rigorous. However, freezing rain and ice in extreme weather have brought serious impacts on conventional railway passenger trains, resulting in trains not being able to run on time, increasing train running time and being forced to stop during running, which seriously affects the running order of railway trains. Therefore, the present invention can solve this problem, improve deicing efficiency and be more flexible, and can decide whether to put it into use at any time according to the freezing state of the line. Summary of the invention

The interlocking saw is combined with the spike-tooth belt, the annular tooth saw, the spike-tooth belt transmission wheel and the spike-tooth belt driven wheel on the bracket. The spike-tooth belt performs an annular motion around the spike-tooth belt driven wheel driven by the pneumatic wheel motor to remove frozen ice from the conventional railway contact network.

[0019] The front end of the 10-bite saw has a tooth beak. When the 10-bite saw composed of the 1-bite saw upper arm and the 3-bite saw lower arm moves relative to each other, the frozen ice on the contact network can be bitten and cut at the moment of contact, so that the volume of the frozen ice hanging column can be rapidly reduced.

[0020] The deicing device is suitable for the contact network of conventional railways. Two rows of 8-spike tooth belts are installed on the 9 brackets. When the 8-spike tooth belt moves in a high-speed circular motion around the 4-spike tooth belt driven wheel under the drive of the 6-pneumatic wheel motor, it forms intensive knocking with the contact network, thereby breaking the residual frozen ice on the contact network.

[0021] The deicing device is suitable for conventional railway contact network, wherein the two interlocking saw double-acting wheels are on the five-spike tooth belt drive wheel and are driven by the six-pneumatic wheel motor.

[0022] The deicing device is suitable for conventional railway contact network. The seven annular saw teeth can be installed in different directions according to the running requirements and can also be used in different running directions of the train.
