Pantograph with stable contact pressure

Abstract

The invention discloses a pantograph with stable contact pressure. The pantograph comprises a bottom plate, a hydraulic thruster, a rubber spring I, a mounting seat I, a lower arm, a rubber spring II,a mounting seat II, a lower guide rod, a mounting seat III, an upper arm, an upper guide rod, a mounting seat IV, a pantograph head framework, a steel spring, a pantograph head, a carbon sliding plate, a light source mounting hole and a photosensitive plate. The bottom plate, the rubber spring I, the rubber spring II, the mounting seat I, the mounting seat II and the mounting seat III form a bottom device; the bottom plate, the lower arm, the lower guide rod and the upper arm form a lower hinge four-rod mechanism; the lower arm, the upper arm, the upper guide rod and the pantograph head framework form an upper hinge four-rod mechanism; and the pantograph head framework, the steel spring, the pantograph head, the carbon sliding plate and the photosensitive plate form a pantograph head device. The hinge four-rod mechanism principle, the hinge sliding block mechanism principle and the lever principle are applied, the structure is simple, the action is flexible, the pantograph-catenary contact pressure can be adjusted within a certain threshold value, the pantograph-catenary contact state can be better improved, and the current collection quality is improved.

Description

technical field [0001] The invention relates to a pantograph, in particular to a pantograph with simple structure, flexible action and stable contact pressure. Background technique [0002] All high-speed trains use electric traction. The electric energy required by the train comes from the catenary, and the electric energy is removed from the catenary through a mechanical mechanism, which is the pantograph. Ensuring smooth contact between the pantograph and the catenary is an important condition for the train to obtain good flow. Excessive pantograph-catenary vibration will not only cause poor flow of locomotives, damage locomotive electrical, accelerate wear between pantograph-catenary, and in severe cases, system power failure and train stoppage will result in huge economic losses. Therefore, it is urgent to design a pantograph with simple structure and stable contact pressure. Contents of the invention [0003] The object of the present invention is to provide a pant...
