The invention discloses a pantograph head longitudinal buffer structure capable of being integrally applied, which comprises a spring barrel for hanging a pantograph head, a vertical buffer structure is arranged in the spring barrel, and a longitudinal buffer structure is arranged near the spring barrel and perpendicular to the spring barrel. The longitudinal buffering structure comprises a branch pipe welding piece, a front end cover, a rear end cover, a sliding shaft (with an anti-rollover function), a buffering piece, a sliding bush, a check ring, a first fastener and a second fastener. By arranging the longitudinal buffer structure, the hard point impact of the pantograph catenary is reduced, and the current collection performance of the pantograph catenary is improved. The problem that a single-slide-plate pantograph of a current mainstream high-speed motor train unit and a newly researched and developed higher-speed pantograph do not have longitudinal buffering in the driving direction is solved.

    本发明公开了一种可集成应用的受电弓弓头纵向缓冲结构,包括悬挂弓头的弹簧筒,弹簧筒内设有垂向缓冲结构,在弹簧筒附近与弹簧筒垂直的位置设有纵向缓冲结构。纵向缓冲结构包含支管焊接件、前端盖、后端盖、滑动轴(带防侧翻)、缓冲件、滑动衬套、挡圈、紧固件一、紧固件二。通过设置纵向缓冲结构,降低了弓网硬点冲击,提高了弓网受流性能。解决了目前主流高速动车组的单滑板受电弓及新研发的更高速度受电弓无行车方向的纵向缓冲的问题。
