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.

    本发明提供一种铁路货车钩头型楔键防松机构及铁路货车,涉及铁路货车领域,防松机构用于传动轴与曲拐之间的钩头型楔键的防松连接,该防松机构包括:第一杆,第一杆可拆卸滑动连接在曲拐的腹板上;第二杆,第二杆的中部铰接在第一杆靠近钩头型楔键的一端上;第二杆的一端顶靠在钩头型楔键的外露端上,第二杆的另一端顶靠在腹板上;紧固组件,紧固组件设置在第一杆的另一端与腹板之间,紧固组件能够将第一杆紧固在腹板上,该机构第二杆的一端压紧位置可微调整,且组装后将第一杆上紧固组件的预紧力转换为第二杆的一端对钩头型楔键外露端持续的压紧力,避免了钩头型楔键松动和脱落的发生,完善了钩头型楔键防松和防脱落技术和功能。
