| abstract |
The invention relates to a power-driven parking slip-preventing device, comprising a driving box and a plurality of braking assemblies as well as two braking rails, wherein a plurality of braking assemblies are arranged in a parallel manner, the two ends of each braking assembly are provided with mounting mechanisms matched with a road rail, the two braking rails are respectively connected with the braking assemblies in a mounting manner, adjacent braking assemblies are connected by virtue of a transmission shaft and the braking assemblies are connected with the driving box by virtue of the transmission shaft, and the end part of the transmission shaft and spindles of the braking assemblies are connected by virtue of a joint transmission mechanism. In the invention, a joint mechanism at the end part of the transmission shaft provides transmission to each braking assembly, and the joint mechanism can realize transmission of torque and also can realize axial swinging in certain angle, thus rigid impact can be avoided by combining the side winding characteristic of railway train operation and equipment is protected; and the mechanism is simple, has low processing cost, small overall size and compact structure and has an important significance for railway equipment with limit requirement owning to size reduction of the power-driven parking slip-preventing device. |
