The invention relates to a swing type spike spinning extractor, and belongs to the field of railway construction. A pull-out clamping groove is included. A groove body of the pull-out clamping grooveis narrow in the lower portion and wide in the upper portion and is in a stepped groove shape, the upper portion of the groove body of the pull-out clamping groove is matched with a spike cap of the spike, the lower portion of the groove body is matched with a spike body of the spike, the width of the lower portion of the groove body is consistent with the width of the spike body, and a thicknessof the lower portion of the groove body is smaller than a distance between a nail cap and a sleeper. The upper end of the groove body of the pull-out clamping groove is hinged to a lever through a pinshaft, after the pull-out clamping groove is matched with the spike, the axis of the pin shaft is perpendicular to and intersects with the center line of the spike, and a pedal is fixed to the tail end of the lever. The spike is pulled out by means of self-weight and swing of a human body, the operation process is very safe and labor-saving, a pillow surface is not damaged, electric power supplyis not needed, the use cost is extremely low, and a construction period is greatly shortened.
本发明涉及一种摇摆式道钉自旋拔出器，属于铁路施工领域。包括拔出卡槽，拔出卡槽的槽体下窄上宽呈阶梯槽状，拔出卡槽的槽体上部分与道钉的钉帽匹配，槽体的下部分与道钉的钉身匹配，槽体下部分的宽度与钉身的宽度一致，槽体下部分的厚度小于钉帽到枕木的距离，拔出卡槽的槽体上端通过销轴铰接杠杆，拔出卡槽与道钉匹配后，销轴轴线与道钉中心线垂直并相交，杠杆尾端固定踩板。依靠人体的自重和摇摆来拔出道钉，操作过程非常安全和省力，也不损伤枕面，无需电力供应，使用成本极低，大大节约工期。
