Abstract

The utility model discloses a lower acting type car coupler lifting rod of a railway wagon, which solves the problem that time and labor are wasted when a car coupler lifting rod and a lower lock pin are quickly disassembled in the prior art. An outward U-shaped forked structure movably connected with the lower lock pin is arranged at the end of the hook lifting rod and comprises a U-shaped fork, a bolt, a nut and a wear-resistant sleeve, the U-shaped fork is located at the end of the hook lifting rod and provided with a pair of bolt holes penetrating in the axial direction, the wear-resistant sleeve is fixed to an opening of the U-shaped fork through the bolt and the nut, and the wear-resistant sleeve is connected with the hook lifting rod. A window is defined by the U-shaped fork and the abrasion-resistant sleeve and matched with the lower lock pin. The coupler lifting rod and the lower lock pin can be quickly disassembled, the coupler lifting rod can be replaced by disassembling the bolt at the head of the coupler lifting rod in a train team, picking for temporary repair is not needed, and the turnover rate of a truck is increased.
