The invention provides a railway wagon hook-headed type wedge key anti-loosening mechanism and a railway wagon, and relates to the field of railway wagons, the anti-loosening mechanism is used for anti-loosening connection of a hook-headed type wedge key between a transmission shaft and a crank throw, the anti-loosening mechanism comprises a first rod, a second rod and a third rod, the first rod is detachably connected to a web of the crank throw in a sliding mode; the middle of the second rod is hinged to the end, close to the hook-headed wedge key, of the first rod. One end of the second rod abuts against the exposed end of the hook-headed wedge key, and the other end of the second rod abuts against the web. The fastening assembly is arranged between the other end of the first rod and the web plate, the fastening assembly can fasten the first rod to the web plate, the pressing position of one end of the second rod of the mechanism can be finely adjusted, and after assembling, the pre-tightening force of the fastening assembly on the first rod is converted into the continuous pressing force of one end of the second rod on the exposed end of the hook-headed wedge key; the hook-headed wedge key is prevented from loosening and falling off, and the anti-loosening and anti-falling technology and function of the hook-headed wedge key are perfected.
