Abstract
The invention discloses electric locomotive pantograph sliding plate and manufacturing method thereof. The manufacturing method comprises the following steps of: a. arranging a groove along the length direction at the bottom of a carbon sliding bar used for connecting a bracket; b. plating conducting slurry in the groove, and enabling the conducting slurry to attach on the surface of the groove of the carbon slide bar so as to form a plating layer; and c. bonding the carbon sliding bar with the plating layer onto the bracket by utilizing a conducting adhesive layer, then heating and solidifying to form an air channel sealed by the plating layer and the conducting adhesive layer. As the plating layer and the carbon sliding bar are integrally formed and very thin, the plating layer is boundto break up when the carbon sliding bar is broken, compressed air in the air channel is bound to leak out, and a pantograph is descended automatically, therefore, the invention solves the problem that the pantograph still works under the condition that the sliding plate breaks up.
Description
technical field [0001] The invention relates to a sliding plate technology for an electric locomotive, in particular to a pantograph sliding plate of an electric locomotive used in conjunction with an automatic lowering device and a manufacturing method thereof. Background technique [0002] During the operation of the locomotive, the pantograph slide is constantly impacted and vibrated frequently by the catenary. When the slide plate is broken, under the condition of being continuously impacted and vibrated by the catenary, the strength of the broken part is greatly reduced, and the edge is easily broken and falls off to form a groove. When the locomotive turns, the catenary is easily stuck, causing damage to the bow and the net, and even serious safety accidents. For this reason people have developed a kind of automatic lowering system that is used for pantograph, to avoid the generation of above-mentioned situation. The basic principle of the automatic lowering bow syst...
