The invention relates to a wheel set blocking device which comprises a blocking body, a hinge mechanism and a driving mechanism. The hinge mechanism comprises a first connecting base, a second connecting base, a first connecting piece and a second connecting piece, the first connecting base is installed on the side portion of the blocking body, and the second connecting base and the first connecting base are oppositely arranged. The first connecting piece and the second connecting piece are arranged between the first connecting base and the second connecting base at intervals in the height direction of the blocking body, and the first connecting piece and the second connecting piece are oppositely arranged. One ends of the first connecting piece and the second connecting piece are movably connected with the first connecting base, and the other ends are movably connected with the second connecting base. During operation, the blocking body can be flatly placed on the track under the action of the hinge mechanism, namely, the bottom of the blocking body is attached to the track so that the contact area of the blocking body and the track is large, the stability of the blocking body placed on the track can be guaranteed, meanwhile, the blocking body can be prevented from being damaged due to an overlarge stress, and the service life of the wheel set blocking device is prolonged. The use cost is reduced.
本发明涉及一种轮对阻挡装置,包括阻挡体、铰链机构及驱动机构。铰链机构包括第一连接座、第二连接座、第一连接件及第二连接件,第一连接座安装于阻挡体的侧部,第二连接座与第一连接座相对设置。第一连接件与第二连接件沿阻挡体的高度方向间隔地设于第一连接座与第二连接座之间,且第一连接件与第二连接件相对设置。第一连接件与第二连接件的一端均与第一连接座活动连接,另一端均与第二连接座活动连接。作业时,阻挡体在铰链机构的作用下能平整地放置在轨道上,即阻挡体的底部附着在轨道上,这样阻挡体与轨道的接触面积大,能保证阻挡体放置在轨道上的稳定性,同时还能避免阻挡体受力过大而损坏,延长轮对阻挡装置的使用寿命,降低使用成本。
