The invention belongs to the technical field of railway wagon braking, particularly relates to a railway wagon hand braking chain protection device and solves the problem that the driving safety is influenced by breaking of a hand brake pull rod reinforcing rib or a hand braking chain. The railway wagon hand braking chain protection device comprises a fixed pulley support assembly fixed at an end beam of a railway wagon and positioned under a hand braking chain relatively and a hand braking chain protection device fixed on a traction beam; and the fixed pulley support assembly and the hand braking chain protection device are in assembly welding or connected through fastening pieces. Through adoption of the railway wagon hand braking chain protection device, the problem that after a conventional hand braking device is released, the hand braking chain droops under the fixed pulley, the release resistance is high since the chain droops greatly to influence the gravity greatly, and thus the hand braking device is not easy to release or cannot be released in place, so that wheels are scratched is solved.
