Translational high-speed train pantograph system

Technical Field

The utility model belongs to the technical field of high-speed train corollary equipment, a translation formula high-speed train pantograph system is related to.

Background

The pantograph is one of main components for ensuring safe and reliable operation of a high-speed train. The electric locomotive obtains the electric energy through the sliding contact between pantograph slide and the contact net wire, and when the moving pantograph slide slides over the relatively static contact net, the contact net receives external force interference, so produce dynamic interact between pantograph slide and contact net, and the pantograph-catenary system produces the vibration of specific form. When the vibration is violent, the pantograph slide plate can be separated from the contact with a contact network to form off-line, electric arcs and sparks are generated, the insulation damage of electric appliances is accelerated, the electromagnetic interference is generated on communication, the current receiving is directly influenced, even the power supply is interrupted instantaneously, and the high-speed train loses traction force and braking force. When the contact force between the pantograph and the pantograph nets is too large, although the off-line rate can be greatly reduced, the abrasion between the contact net and the pantograph slide plate is increased, so that the service life of the pantograph slide plate is shortened. The existing contact net is generally made of copper alloy materials, the hardness is relatively high, and the contact surface of the pantograph slide plate is generally made of graphite materials, and the hardness is relatively low. Therefore, a good pantograph relationship is a basic prerequisite to ensure that a high-speed train receives current stably and reliably.

In order to solve the problem, at present, a contact net is erected above a high-speed train track along the track direction according to a Z-shaped erecting mode, and compared with a straight contact net erected along the track, the length of a contact net line is relatively prolonged, so that more raw material copper is consumed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a translation type high-speed train pantograph system, which solves the problems that the pantograph slide plate in the prior art is unevenly worn and the service life is shortened due to the fixed-point contact between the pantograph slide plate and a contact net; the contact net line is in a Z shape, so that the line is longer than a straight line, and copper resource waste is caused.

The utility model adopts the technical proposal that the translation type high-speed train pantograph system comprises a bracket, wherein the upper surface of the bracket is provided with an electric cylinder, and the electric cylinder is upwards driven and connected with a pantograph slide plate; the lower part of the support is hinged with an upper arm rod and a balance rod, the lower part of the upper arm rod is hinged with a pull rod and a lower arm rod, the lower end of the balance rod is hinged with the upper part of the lower arm rod, the lower ends of the pull rod and the lower arm rod are hinged with a chassis, and the chassis is installed on the roof of the traction locomotive through a plurality of insulators.
