The invention discloses a tractor and a towing vehicle hook device for a rail transit vehicle. The towing vehicle hook device for a rail transit vehicle is used for connecting the tractor with a to-be-transferred vehicle, and is characterized by comprising: a first connecting piece (1), which is used for being connecting with the tractor; a second connecting piece (2), which is used for being connected with the to-be-transferred vehicle; and a vehicle towing rod, one end of which is hinged to the first connecting piece (1), and the other end of which is hinged to the second connecting piece (2). By the adoption of the structure, the tractor and the to-be-transferred vehicle can be connected, due to the fact that the two ends of the vehicle towing rod are hinged, when the to-be-transferredvehicle and the tractor rotate in the height direction and the horizontal direction, rotation can be achieved through hinging, and the risks of hard strain and unhooking of the towing vehicle hook device are avoided.
本发明公开了一种牵引车及其用于轨道交通车辆的牵车钩装置,用于连接牵引车和待转移车辆,其特征在于,包括:第一连接件(1),所述第一连接件(1)用于与所述牵引车相连;第二连接件(2),所述第二连接件(2)用于与所述待转移车辆相连;牵车杆,所述牵车杆一端铰接在所述第一连接件(1)上,另一端铰接在所述第二连接件(2)上。采用上述结构可实现牵引车和待转移车辆的连接,并且由于牵车杆的两端分别采用铰接,在待转移车辆与牵引车发生高度方向和水平转动时,可通过铰接实现转动,避免了牵车钩装置出现硬拉伤及脱钩的风险。
