The embodiment of the invention relates to mechanical equipment for controlling a turnout, in particular to a squeezing-off device of a railway switch machine. The railway switch machine comprises locking iron, a movable contact group, a static contact group and an extrusion device. The extrusion device comprises a first action piece, a first installation piece and an extrusion indication piece. The first mounting piece is provided with a first mounting hole; the first action piece is located in the first mounting hole, the movable contact group comprises a matching piece matched with the first action piece, and the first action piece can move towards the direction of the matching piece along the first mounting hole when the locking iron generates displacement so as to jack up the matching piece, so that the movable contact group and the static contact group are electrically disconnected; at least part of the extrusion-off indication piece is located in the first installation hole, and when the locking iron generates displacement, the extrusion-off indication piece is pushed away from the first installation hole by the first action piece and is kept outside the first installation hole. According to the squeezing-off device provided by the embodiment of the invention, a worker can conveniently judge the reason of a squeezing-off accident from the appearance.
本申请的实施例涉及操纵道岔的机械设备,具体涉及一种铁路转辙机的挤脱装置。铁路转辙机包括锁闭铁、动接点组、静接点组和挤脱装置。挤脱装置包括第一动作件、第一安装件和挤脱表示件。第一安装件具有第一安装孔;第一动作件位于第一安装孔中,动接点组包括与第一动作件配合的配合件,第一动作件能够在锁闭铁产生位移时,沿第一安装孔朝配合件的方向移动,以将配合件顶起,使动接点组与静接点组断开电性连接;至少部分的挤脱表示件位于第一安装孔内,在锁闭铁产生位移时,挤脱表示件被第一动作件推离第一安装孔,并保持在第一安装孔外。本申请的实施例提供的挤脱装置便于工作人员从外观上判断挤脱事故发生的原因。
