AI Technical Summary
Existing railway overhead contact line de-icing devices suffer from limitations in operating conditions, high costs, low efficiency, and the need to wait for a window of opportunity, especially affecting the normal operation of electrified vehicles during periods of continuous freezing rain.
The system adopts a combination design of main support frame, frame side beams, support components, pneumatic lifting rod, U-shaped mirror metal channel, high-temperature ice melter, ice-breaking steel blade, double-acting cylinder and ice-breaking clamp. Through the cooperation of high-temperature ice melting and ice-breaking steel blade, it can quickly melt and remove the ice layer on the contact wire. The cooperation of double-acting cylinder and ice-breaking clamp ensures the comprehensiveness and safety of de-icing operation.
It improved de-icing efficiency, ensured the normal operation of electrified railways in icy and snowy weather, reduced the risk of damage to the overhead contact line, and reduced maintenance costs.
