Abstract
The utility model discloses a railway vehicle coupling buffering device which solves the technical problem that an anteposition vehicle of a coupling railway vehicle is prone to collide hook and drag hook with a mechanical vehicle behind the anteposition vehicle. The railway vehicle coupling buffering device comprises the anteposition vehicle (10), a retroposition vehicle (11), and a coupling car coupler (14), wherein a buffering device is respectively arranged on the anteposition vehicle and the retroposition vehicle. The buffering device comprises a fixing sleeve bucket (3) and a telescopic sleeve pipe (2). A pin roll pass-hole (9) is arranged in the center of the bottom of the fixing sleeve bucket (3). A pin roll (4) is arranged inside the telescopic sleeve pipe (2) and connected with a buffering spring (5) in a sleeved mode. One end of the pin roll (4) arranged in the telescopic sleeve pipe (2) is fixedly welded with the inner side of a head connecting panel (1). The other end of the pin roll (4) arranged in the telescopic sleeve pipe (2) penetrates through the pin roll pass-hole (9) arranged in the center of the bottom of the fixing sleeve bucket (3) and is arranged outside the fixing sleeve bucket (3). The railway vehicle coupling buffering device is simple in structure, convenient to install, and particularly suitable for railway construction.
