The invention discloses a railway wagon hand brake chain rolling device. Comprising a chain formed by connecting a plurality of same chain rings, and the chain rolling device is composed of gears, a chain rolling shaft and a chain guide plate. The gear is in driving connection with a driving gear of the hand brake; the chain rolling shaft is coaxially connected and fixed with the gear, three groups of chain rolling teeth capable of being embedded into the chain ring holes to drive the chain are symmetrically arranged on the circumference of the chain rolling shaft, and three groups of chain rolling grooves capable of being limited and vertically embedded into the chain rings are symmetrically formed between the adjacent chain rolling teeth; the chain guide plate is provided with an arc surface and plane sections in arc transition connection with two ends of the arc surface; the chain guide plate is arranged above the chain rolling shaft, and the arc face and the chain rolling shaft are coaxially arranged and fixed to the hand brake machine shell. A chain channel is formed between the chain guide plate arc face and the chain rolling shaft. The chain is driven through meshing between the tooth-shaped structure of the chain rolling shaft and the chain, it is guaranteed that the actual braking multiplying power is not changed, the chain is not wound around the chain rolling shaft, the transmission efficiency is effectively improved, and the problem that the rolling-in amount of the chain is limited is solved.

    本发明公开了一种铁路货车手制动机卷链装置。包括由数个相同链环相接构成的链条,卷链装置由齿轮、卷链轴和链导板组成;齿轮,与手制动机的驱动齿轮驱动连接;卷链轴,与齿轮同轴连接固定,卷链轴圆周上对称设置三组可嵌入链环孔中驱动链条的卷链齿、相邻卷链齿之间对称形成三组可限位竖直嵌入链环的卷链槽;链导板,具有圆弧面、和圆弧面两端弧形过渡连接的平面段;链导板设置于卷链轴上方、圆弧面与卷链轴同轴心布置固定于手制动机壳上;链导板圆弧面与卷链轴之间构成链条通道。本发明采用卷链轴的齿形结构与链条之间的啮合来驱动链条,保证了实际制动倍率不变,且链条不在卷链轴上缠绕,有效提升了传动效率,解决了链条卷入量的限制问题。
