Abstract

The invention discloses a single arm pantograph with a ternary system structure and relates to the technical field of wire net current receiving pantographs adopted on electric traction locomotives. The single arm pantograph comprises an underframe, a pantograph rising spring, a lower arm rod assembly, an upper arm rod assembly and a pantograph assembly, wherein the pantograph assembly comprises apantograph head support, a micro-motion spring, a connecting frame, a restoring spring, a sliding plate support and a sliding plate, the pantograph head support is used for connection with the upperend of the upper arm rod assembly, the sliding plate is fixed to the sliding plate support, the micro-motion spring is arranged between the pantograph head support and the connecting frame, the restoring spring is arranged between the connecting frame and the sliding plate support, and the micro-motion spring and the restoring spring are identical in displacement. The single arm pantograph adoptsthe ternary system structure provided with the pantograph rising spring, the restoring spring and the micro-motion spring, reduction mass of a pantograph head can be better dispersed, a pantograph off-line phenomenon is improved, a pantograph net following performance is improved, better current-receiving quality is obtained, the pantograph failure rate is reduced, and productivity effect of operation is improved.

Description

technical field [0001] The invention relates to the technical field of a pantograph used on an electric traction locomotive to receive line network current, and more specifically relates to a single-arm pantograph with a ternary system structure. Background technique [0002] Electric traction locomotive is the electrical equipment that obtains electric energy from the catenary, and is installed on the roof of the locomotive or motor car, referred to as the pantograph. Pantographs can be divided into single-arm bows and double-arm bows, both of which are composed of slide plates, upper frames, lower arm rods (lower frames for double-arm bows), underframes, bow springs, transmission cylinders, supporting insulators and other components. Diamond pantograph (double-armed bow), also known as diamond pantograph, was very common in the past, but was gradually eliminated due to high maintenance costs and the tendency to break the catenary when a fault occurs. In recent years, singl...
