Self-lubricating modular metal roller electric locomotive pantograph head with damping structure

Abstract

The invention provides a self-lubricating modular metal roller electric locomotive pantograph head with a damping structure. Pure carbon sliding plates are arranged on the two upper end surfaces of aU-shaped insulating base, and more than one group of metal rollers are arranged on the horizontal bottom plate of the base; the setting mode of each group of metal rollers is as follows: the lower parts of every two T-shaped insulating supports extend into grooves of a horizontal bottom plate respectively, and are arranged on fixing bolts which are screwed into the outer side of the horizontal bottom plate through holes in the horizontal bottom plate, spring damping mechanisms are symmetrically arranged on the left side and the right side of each insulating support, and the two metal rollers are arranged between the two supports through fixing shafts; and the structure of the metal rollers are is characterized in that the metal cylinders sleeve the metal shafts through insulating bearings,annular current-receiving electric brushes are fixed on the metal shafts, and the outer surfaces of the annular current-receiving electric brushes are in contact with the inner walls of the metal rollers. The self-lubricating modular metal roller electric locomotive pantograph head has the self-lubricating effect, is in flexible contact with an arch net and forms rolling friction fit, and has thecharacteristics of being capable of adapting to requirements of traction power of a train, being longer in service life and the like.

Description

technical field

[0001] The invention relates to the technical field of rail transit, in particular to a pantograph bow head for electric traction locomotives such as subway light rails. Background technique

[0002] Electric traction locomotives usually use "pantograph-catenary" to contact each other to transmit electric energy. Usually, the pantograph is installed on the top of the train car and supports a single or multiple carbon slides, and the catenary is suspended above the roof by the towers set along the railway line, and the electrical energy passes through the pantograph in contact with the carbon slides through the catenary. transmitted to the car. The pantograph-catenary system is the key for the train to obtain stable electric energy.

[0003] In order to make the friction between the contact line and the surface of the carbon skateboard as uniform as possible during the running process of the train, the poles and towers for suspending the contact line are gen...
