The invention discloses an opening type hook lifting rod seat. Comprising a base and a flat plate base body perpendicular to the base, the flat plate base body is provided with a notch with an opening in the upper end, the notch is composed of a lower flat hole and a U-shaped hole with the hole diameter larger than that of the lower flat hole, and round pin holes are formed in the two sides of the top of the U-shaped hole of the notch; mounting holes fixedly connected with a vehicle body are formed in two wings of the base; the flat hole is in a long strip shape in the radial direction, the two side edges of the flat hole are vertically arranged, and the radial long-strip-shaped flat hole is matched with the hook lifting rod flat portion of the hook lifting rod combination portion and used for preventing the hook lifting rod from rotating around the center of the rod. The axial sections of the two vertically-arranged side edges of the flat hole are opposite arcs bent towards the outer side, the arc structures are used for increasing the swing angle of the hook lifting rod in the flat hole, and the situation that the hook lifting rod is excessively collided and damaged during swing and displacement in the flat hole is avoided. The flat hole of the lifting rod seat is in limiting contact with the flat part of the coupler lifting rod, so that the coupler lifting rod can be prevented from accidentally rotating to unlock the coupler, the coupler lifting rod can be conveniently mounted and dismounted through the open structure, and the mounting and maintenance efficiency is high.

    本发明公开了一种开口型钩提杆座。包括底座及其与底座垂直布置的平板基体,平板基体设置上端开口的缺口,缺口由下部扁孔和孔径大于下部扁孔的U型孔组成,缺口的U型孔顶部两侧设置圆销孔;底座两翼设置与车体连接固定的安装孔;扁孔径向为长条形,两侧边竖直设置,径向长条形的扁孔与钩提杆结合部的钩提杆扁平部位配合,用于防止钩提杆绕杆中心转动;扁孔竖直设置的两侧边沿轴向截面为相对的向外侧弯曲的弧形,弧形结构用于增加钩提杆在扁孔内的摆角,避免钩提杆在扁孔内摆动、位移时过度冲撞损坏。本发明提杆座扁孔与钩提杆扁平部位限位接触能够避免钩提杆意外转动解锁车钩,且其开口型结构能够方便安装和拆卸钩提杆,安装和维修效率高。
