The invention relates to the technical field of rail transit, and discloses a two-way abutting anti-slip iron shoe. The shoe comprises a bottom plate, symmetrical sliding plates are arranged on the upper end face of the bottom plate, the bottom plate is movably connected with the sliding plates, and the sliding plates are fixedly connected with coupling base plates. Through an air valve in the middle of a pressure cylinder, piston rods on the two sides contract under the pressure difference to drive clamping plates on the two sides and limiting grooves to be clamped, theft is effectively avoided, it is guaranteed that the clamping plates and the limiting grooves abut against wheels, on the other hand, the phenomenon that a gap is too large due to random operation is avoided, and the vehicle sliding probability is reduced; if individual forgetting exists in the evacuation process, due to the fact that some anti-slip iron shoes cannot prevent a train from moving, when the train moves, large pressure enables the clamping plates to be flattened, meanwhile, along with pressure relief, due to the fact that the clamping plates are flattened, the phenomenon that the iron shoes are draggedor wheels are rolled over and derailed is avoided, safe passing of the wheels is guaranteed, and meanwhile the iron shoes can be swept to one side when the next wheel collides with the driving lever.

    本发明涉及轨道交通技术领域,且公开了一种双向抵紧的防溜铁鞋,包括底板,所述底板的上端面设有对称的滑板,所述底板和滑板活动连接,所述滑板固定连接偶垫板。通过压力缸中部的气阀,两侧活塞杆在压力差下收缩带动两侧的夹板和限位槽夹紧,有效规避了被盗,保证夹板与限位槽与车轮的抵紧,另一方面,进而规避了因随意操作导致间隙过大的现象,降低溜车概率,若在撤离时存在个别遗忘,由于个别防溜铁鞋无法阻止列车移动,列车移动时,较大的压力使夹板压平,同时伴随着泄压,由于夹板被压平,避免铁鞋被拖行或车轮轧过脱轨的现象,保证车轮的平安驶过,同时下个车轮在撞击到另一侧的拨杆时会将铁鞋扫向一边。
