The invention relates to the field of rail locking, in particular to a rail clamping device for a rail. Connecting pieces of the two brake arms of the rail clamping device for the rail are hinged, the rail clamping device for the rail further comprises a transmission piece and a direct-acting driving mechanism, the direct-acting driving mechanism is located on the outer sides of the two brake arms, an elastic piece is arranged between the transmission piece or the connecting piece and the frame body, and when the transmission piece is located at a release station, the elastic piece is stressed to deform. And when the direct-acting driving mechanism loses power, the transmission piece is driven to move from the releasing station to the braking station. In the up-and-down moving process of the transmission piece, the position of the brake arm is influenced through the hinged position of the connecting piece, then the position of the resisting arm can be influenced for braking and unlocking, and in other words, the arrangement position of the direct-acting driving mechanism is not limited by the power arm; therefore, the problem that in the prior art, a direct-acting driving mechanism of a rail clamping device is arranged between power arms of a brake arm, and the model selection of a hydraulic cylinder is limited due to the limitation of the space between the power arms is solved.
本发明涉及轨道锁止领域,尤其涉及一种轨道用夹轨器。轨道用夹轨器的两个制动臂的连接件铰接,轨道用夹轨器还包括传动件以及直动驱动机构,直动驱动机构位于两个制动臂的外侧,传动件或连接件与架体之间设置有弹性件,传动件位于释放工位时弹性件受力变形,以在直动驱动机构失去动力时驱动传动件从释放工位运动至制动工位。在传动件上下移动的过程中,通过连接件的铰接位置影响制动臂的位置,进而能够影响阻力臂的位置去进行制动和解锁,也就是说进而使得直动驱动机构的设置位置不受动力臂的限制,进而解决了现有技术中夹轨器的直动驱动机构布置在制动臂的动力臂之间,受到动力臂之间空间的限制导致液压缸的选型受到限制的问题。
