Abstract
A self-locking anti-slip rail braking device is provided. The rail braking device includes a ladder-shaped support, a lifting unit, a roller-and-wedge plate mechanism, a roller support, and a rail clamping unit. The ladder-shaped support is connected under a surface of a balance beam of a port facility, and is connected at a middle part thereof with the lifting unit. A lower end of the lifting unit is hinged to two sides of the roller support. The roller support is provided on an upper end surface thereof with the roller-and-wedge plate mechanism, and is provided at a middle part thereof with the rail clamping unit. An upper end of the rail clamping unit serves as a force application end and is configured to match the roller-and-wedge plate mechanism, and a lower end of the rail clamping unit serves as a rail clamping end corresponding to two lateral sides of a rail.
