Abstract

The invention discloses a high-speed pantograph head, comprising a sliding plate, small bow angles, large bow angles and a frame-shaped spring, wherein the section of the sliding plate is in a stream line form, the lower part of the sliding plate is an elongated sliding plate slot, the slot is embedded with carbon slide blocks or other materials, the frame-shaped spring is connected below the sliding plate by virtue of a bracket, the front end of the frame-shaped spring is connected with the sliding plate by virtue of a support and the bracket, the rear end of the frame-shaped spring is hinged with the upper frame of a pantograph, and a group of large bow angles are inserted and fixed in a hinge at the upper end of the upper frame of the pantograph. Under the coordination of a pantograph balanced beam, the frame-shaped spring can always maintain the sliding plate of the pantograph to be parallel to a guide rail plane, and the sliding plate can be always in close contact with a contact wire under the regulating action of the bracket. The structure of the pantograph head is simple, the weight is light, the air resistance when the pantograph head moves, the impact resistance is high, the current of the pantograph at a high speed is favourable, the current of the pantograph of a train on a conventional railway or a light railway can be improved.

Description

technical field [0001] The invention relates to a pantograph bow head, in particular to a high-speed pantograph bow head. Background technique [0002] On vehicles such as electric locomotives, EMUs or electric operating vehicles in electrified railways and urban rail transit, pantographs are required to take current from the catenary. The electrified railway adopts electric traction. When the train is in motion, it uses the pantograph to obtain electric energy from the catenary. In order to ensure the smooth and safe operation of the train, it is necessary to ensure that the power supply is absolutely reliable and uninterrupted, that is, the current receiving state of the pantograph is good. Otherwise it will affect the operation of the train and the performance of the electric drive system. In the high-speed running state, the requirements for the pantograph are higher. [0003] In order to ensure good current receiving characteristics of the pantograph-catenary, the str...
