Description

Technical Field

[0001] This utility model relates to the field of de-icing mechanisms, specifically to a de-icing mechanism for high-speed railway overhead contact lines. Background Technology

[0002] De-icing of high-speed rail overhead contact lines refers to the removal of ice layers adhering to the contact lines of high-speed railways to ensure their normal operation. The overhead contact lines are crucial power supply facilities for electric locomotives, providing traction power through the sliding contact between the pantograph and the contact line. In winter, during rain and snow, the contact lines are prone to icing, which not only affects power transmission efficiency but can also lead to equipment damage and train interruptions. A Chinese patent (authorization announcement number CN211351646 U) discloses a de-icing device for tram overhead contact lines. This patented technology can be retrofitted to the roof of existing tram carriages at a low cost. The device has a simple structure and a detachable installation method, making it convenient to use. It employs heat-conducting pulleys with heating wires to accelerate the melting of ice on the contact line, resulting in excellent de-icing effects. However, in cases of heavy icing, effective hot-sliding de-icing is not possible, requiring mechanical cutting of large ice volumes for rapid de-icing. Therefore, those skilled in the art have provided a high-speed rail overhead contact line de-icing mechanism to address the problems mentioned in the background art. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a high-speed rail contact wire de-icing mechanism, including a contact wire, a fixed plate, a heater, a mechanical ice cutter, a shaft column, rolling wheels, and a hot melt sheet. Mechanical ice cutters of the same specification are installed on both the upper and lower sides of the fixed plate. Two shaft columns of the same size are installed between the fixed plates. Multiple rolling wheels are installed in the middle of the shaft columns. Hot melt sheets are installed at both the upper and lower ends of the rolling wheels. The contact wire is provided between the rolling wheels. Heaters of the same specification are installed on both the left and right ends of the fixed plate.

[0004] Preferably, multiple No. 1 ear plates are installed on the left and right side walls of the fixing plate, a heater is installed between the No. 1 ear plates, and a No. 2 ear plate is installed on the side wall of the heater. The No. 1 ear plates and the No. 2 ear plates are fixedly installed by bolts.

[0005] Preferably, the mechanical ice cutters installed on the upper and lower sides of the fixed plate are fixedly installed with bolts, and a connecting plate is installed on the front side of the mechanical ice cutter, and the cutting body is connected to the connecting plate;

[0006] Preferably: a first cutting head is installed on the front side of the cutting body, multiple serrated heads are provided on both side walls of the cutting body, an extension body is installed on both side walls of the cutting body, and a second cutting head is installed on the front side of the extension body;

[0007] Preferably, a baffle is installed between the fixed plate and the shaft column, a limiting block is installed at intervals on the shaft column, a rolling wheel is installed between the limiting blocks, a heating guide wire is installed inside the heater, the heating guide wire is also installed inside the fixed block, and the other end of the heating guide wire is connected to a hot melt sheet.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. The cutting body is located at the upper and lower ends of the contact wire with a certain distance between them. It will not directly adhere to the contact wire and can be cut off with the No. 1 cutting head when there is a lot of ice. In addition, extension bodies are installed on both sides to effectively remove ice from all four sides of the contact wire.

[0010] 2. This equipment can be retrofitted to the top of existing tram carriages, allowing the rolling wheels to roll in contact with the contact wire for auxiliary rolling. The hot melt sheets are located at the upper and lower ends of the contact wire with a certain gap, so they do not directly adhere to the contact wire. This allows the ice layer attached to the contact wire to melt without damaging the contact wire. Attached Figure Description
