The invention provides a brake chain tensioning device, a hand brake and a railway vehicle, and relates to the technical field of railway vehicle braking. The brake chain tensioning device comprises a first force bearing pull ring and a second force bearing pull ring, the front end of the first force bearing pull ring is connected to a first broken point position of the brake chain, the front end of the second force bearing pull ring is connected to a second broken point position of the brake chain, and the tail end of the first force bearing pull ring and the tail end of the second force bearing pull ring are oppositely arranged. The first end of the elastic telescopic piece is connected to the tail end of the first force bearing pull ring, and the second end of the elastic telescopic piece is connected to the tail end of the second force bearing pull ring. According to the brake chain tensioning device, elastic pre-tightening force can be applied to the brake chain so as to tighten the relaxation allowance of the brake chain, and the abnormal sound and the abrasion degree of the brake chain generated in the running process of a railway vehicle are reduced.
本发明提供一种制动链张紧装置及手制动机、轨道车辆,涉及轨道车辆制动技术领域。制动链张紧装置包括:第一承力拉环及第二承力拉环,第一承力拉环的前端连接于制动链的第一断点位,第二承力拉环的前端连接于制动链的第二断点位,第一承力拉环的尾端与第二承力拉环的尾端相对设置;弹性伸缩件,弹性伸缩件的第一端连接于第一承力拉环的尾端,弹性伸缩件的第二端连接于第二承力拉环的尾端。本发明提供的制动链张紧装置,可以向制动链施加弹性预紧力以收紧制动链的松弛余量,减小制动链在轨道车辆运行过程中产生的异响和磨损程度。
