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.

    本发明公布了一种具有稳定接触压力的受电弓,包括底板、液压推进器、橡胶弹簧Ⅰ、安装座Ⅰ、下臂、橡胶弹簧Ⅱ、安装座Ⅱ、下导杆、安装座Ⅲ、上臂、上导杆、安装座Ⅳ、弓头构架、钢弹簧、弓头、碳滑板、光源安装孔以及感光板。底板、橡胶弹簧Ⅰ、橡胶弹簧Ⅱ、安装座Ⅰ、安装座Ⅱ和安装座Ⅲ组成底部装置;底板、下臂、下导杆和上臂构成下部铰链四杆机构;下臂、上臂、上导杆和弓头构架构成上部铰链四杆机构;弓头构架、钢弹簧、弓头、碳滑板和感光板组成弓头装置。本发明运用了铰链四杆机构原理、铰链滑块机构原理和杠杆原理,结构简单,动作灵活,可将弓网接触压力调节在一定阈值内,能较好的改善弓网接触状态,提高受流质量。
