The invention belongs to the field of traction transportation, and particularly discloses a towing device and a tractor, the towing device comprises a traction bolt, a traction pin arranged above the traction bolt and a mounting plate used for mounting the traction bolt and the traction pin, the mounting plate is used for being connected with the tractor, and a transverse mounting hole allowing a traction rod of the trailer to be inserted is formed in the traction bolt. A first inserting hole used for being matched with the traction pin in an inserted mode is formed in the upper end of the traction bolt, the first inserting hole is communicated with the mounting hole, the traction bolt is slidably connected to the mounting plate in the vertical direction, and a lifting mechanism used for driving the traction bolt to ascend and descend is arranged on the mounting plate. By the adoption of the scheme, the problems that the traction bolt is fixedly arranged, the traction rod is difficult to lift sufficiently, and the traction bolt cannot directly adapt to civil aviation standard trailer application can be solved.
本发明属于牵引运输领域,具体公开了一种拖挂装置及牵引车,包括牵引栓、设于牵引栓上方的牵引销以及用于安装牵引栓、牵引销的安装板,安装板用于和牵引车连接,牵引栓上开设有横向的供拖车的牵引杆插入的安装孔,牵引栓上端开设有用于和牵引销插接配合的第一插孔,第一插孔和安装孔连通,牵引栓沿竖向滑动连接在安装板上,安装板上设有用于驱动牵引栓升降的升降机构。采用本发明的方案,可以解决牵引栓固定设置,难以对牵引杆进行足够的提升,无法直接适应民航标准拖车应用的问题。
