The invention discloses a locomotive iron shoe self-retracting mechanism which comprises an iron shoe, a connecting rod, a telescopic driving part, a first elastic part and a second elastic part, the high end of the connecting rod is hinged to a bogie, and the low end of the connecting rod is hinged to one end of the iron shoe; the high end of the telescopic driving piece is hinged to the bogie, and the low end of the telescopic driving piece is hinged to the connecting rod and used for driving the connecting rod to rotate so that the low end of the connecting rod can be close to or away from the wheel pair and the track. The brake shoe has the beneficial effects that when the brake shoe is in a braking state, the brake shoe can tightly abut against a wheel pair and a rail under the action of the first elastic piece and the second elastic piece, even if the two-way air cylinder leaks air, the brake shoe can still keep a parking state, the energy-consumption-free long-time anti-sliding function is achieved, and when the brake shoe is in a retracting state, the first elastic piece lifts the brake shoe upwards, so that the brake shoe is stopped. The second elastic piece pushes the connecting rod upwards, and even if the two-way air cylinder leaks air, the iron shoe can be kept in a retracted state.
本发明公开了一种机车铁鞋自收放机构,其包括铁鞋、连杆、伸缩驱动件、第一弹性件及第二弹性件,所述连杆的高端与转向架铰接,所述连杆的低端与所述铁鞋的一端铰接;所述伸缩驱动件的高端与转向架铰接,所述伸缩驱动件的低端与所述连杆铰接,用于驱动所述连杆转动,以使所述连杆的低端靠近或远离轮对和轨道。本发明的有益效果是:铁鞋处于制动状态时,在第一弹性件和第二弹性件的作用下,铁鞋能紧密的与轮对和轨道抵紧,即使双向气缸漏气,铁鞋也能保持驻车状态,实现无能耗长时间防溜车功能,铁鞋处于收回状态时,第一弹性件向上提拉铁鞋,第二弹性件向上推动连杆,即使双向气缸漏气,铁鞋也能保持收回状态。
