Embodiment

[0047] Every year, ice and snow disasters are serious in our country, and electrified railways are completely dependent on the power grid. Once the power grid fails due to weather, the trains usually cannot operate normally. The icing of the catenary will directly affect the quality of the train pantograph receiving current from the catenary, or even fail to receive the current, which can lead to insufficient power supply of the train and reduce the speed of operation, and seriously directly cause the train to stop power and stop running. The icing of the catenary will also increase the wear of the pantograph slide. Its potential dangers also include arc burns due to poor contact between the sliding bow net and the contact wire, contact wire disconnection caused by icing, and so on. In particular, a large number of passenger dedicated lines operated by EMUs have higher train speeds and extremely complex pantograph-catenary relationships, so the requirements for flow quality ar...

Abstract

The invention discloses a pneumatic rotary deicing device. The pneumatic rotary deicing device solves the problems that at present no effective deicing method or equipment for a railway overhead line system exists at home and abroad, and the present requirement for railway maintenance can not be met. The pneumatic rotary deicing device is characterized by comprising a double-H buffering table frame, a servo lifting device (1), a combined type deicing brush, a power system and a control system, wherein the upper end of the servo lifting device (1) is connected with the lower surface of the double-H buffering table frame, the servo lifting device (1) is used for lifting the double-H buffering table frame, the combined type deicing brush is arranged on the upper surface of the double-H buffering table frame, the power system provides power for operation of the pneumatic rotary deicing device, the control system is used for controlling the servo lifting device (1) and the combined type deicing brush, and the combined type deicing brush comprises one or more of a rotary knocking head (2), a rotary steel brush (3) and a rotary nylon brush (4). The pneumatic rotary deicing device is short in deicing time, obvious in effect, and capable of dealing with most icing disasters.

Description

technical field [0001] The invention relates to a pneumatic rotary deicing device. Background technique [0002] The catenary is an important part of the electrified railway. It is a special transmission line that is erected above the railway. The pantograph of the locomotive and its friction receive electricity to provide electric energy for the electric locomotive. The catenary is distributed linearly along with the rails, and with the continuous extension of electrified railways, the length of the catenary is constantly increasing. Entering the new century, my country's electrified railway has been greatly developed, and the mileage of railways in operation has jumped to the second place in the world. [0003] The external environment of the catenary is very harsh. Many places are inaccessible and exposed to wind and sun all the year round. Therefore, the reliability requirements for the catenary are very high. With the rapid development of the national economy, the el...
