Automatic deicing device for overhead line system of electrified railway system

Abstract

The invention provides an automatic deicing device for a contact network of an electrified railway system. The device is arranged at the top of the railway locomotive and moves along with the movement of the locomotive. The device comprises a position driving device which can drive the deicing knife to contact with or leave the contact network. The deicing blade can rotate at a high speed under the driving of the motor, the deicing blade strikes an overhead line system icing body with strong kinetic energy, breaks the overhead line system icing body and enables the overhead line system icing body to fall off, and the residual overhead line system icing body is scraped along with the scraper behind the deicing blade, so that the deicing effect of the overhead line system is achieved.

Description

Technical Field

[0001] The present invention relates to the field of contact network power supply for electrified railway systems, and in particular to an automatic deicing device for a contact network. Background Art

[0002] The catenary is a special type of transmission line erected above railway lines that supplies power to electric locomotives. Due to weather conditions, the catenary often freezes in winter. This ice prevents the locomotive's pantograph from making direct contact with the catenary, preventing the locomotive from receiving power and thus affecting normal train operation.

[0003] Existing de-icing methods mainly rely on manual operations, mainly through mechanical knocking, vibration, impact, milling and other methods. On the one hand, the de-icing efficiency is low, on the other hand, the working environment of the operators is poor, and on the other hand, the operators are prone to personal injury accidents.

[0004] How to use automated devices to replace manual operations to de-ice the contact network is a problem that needs to be solved urgently. Summary of the Invention

[0005] The present invention provides an automatic deicing device for a contact network of an electrified railway system, which solves the problem that an electric locomotive cannot operate when the contact network is frozen.

[0006] The present invention includes a position drive device, an insulation device, and a deicing device. Its characteristics are that, driven by the position drive device, the deicing device reaches the frozen contact network; the ice blade of the deicing device rotates at high speed and strikes the frozen contact network, breaking the ice; and the scraper following it scrapes away the remaining ice on the contact network, thereby achieving the purpose of deicing the contact network.

[0007] In order to protect the safety of personnel and equipment, an insulation device is installed between this device and the locomotive installation part.

[0008] The deicing device comprises a rotating bracket (7) and a deicing blade (9). The deicing blade (9) is provided with a plurality of blade teeth (8) to enhance the deicing effect. The shape and material of the deicing blade (9) can be selected in a variety of ways and can be determined according to the specific conditions of icing.

[0009] The position driving device of the present invention can be a mechanical, pneumatic or hydraulic driving device.

[0010] The beneficial effects of the present invention are: 1) The locomotive is used for power supply and can be carried by the locomotive to remove ice while traveling, thus improving work efficiency. 2) The percussion de-icing method is used to avoid damaging the wires and ensure the safety of personnel and equipment.

[0014] The working details are as follows: Since the overhead contact line is a high-voltage circuit, the system is provided with effective insulation protection by the insulation device (1) to protect the safety of personnel and locomotive equipment.

[0015] The whole system is composed of lower support arm (2), upper support arm (3) and some necessary support components. The position driving device drives the rotating support (7), deicing blade (9) and scraper (8) to reach the position of deicing the overhead contact line.

[0016] When the deicing blade (9) reaches the position of deicing the overhead contact line, the motor (11) is started, and the motor drives the rotating support (7) through the belt set (10) (6) (5) to drive the deicing blade (9) and the cutter tooth (8) to rotate and strike the overhead contact line, followed by the scraper (4) to scrape the residual ice on the overhead contact line, so as to achieve the effect of deicing the overhead contact line.
