Alloy sleeper for supporting steel rail
The invention relates to an alloy sleeper for supporting a steel rail, and belongs to the technical field of coal mine railway transportation equipment. The steel rail sleeper comprises a sleeper body, pressing plates and fastening bolts, the longitudinal section of the sleeper body is trapezoidal, extending edges are arranged at the lower ends of the two sides of the sleeper body, the pressing plates are fixedly arranged on the upper surface of the sleeper body through the fastening bolts, the pressing plates are symmetrically arranged in pairs, and the two symmetrically arranged pressing plates are used for clamping a steel rail. The alloy sleeper has the advantages of low temperature resistance, corrosion resistance, vibration resistance, high pressure bearing capacity, elasticity, strength and durability uniformity, and solves the problems of high rigidity and poor elasticity of a reinforced concrete sleeper, and increased pressure and vibration acceleration borne by a ballast bed, so that pulverization of ballast can be avoided, the problem of increased sinking of a track cannot be caused, and the service life of the track is prolonged. The method is suitable for large-span use; the alloy sleeper is made of alloy steel materials, compared with a wood sleeper or a reinforced concrete sleeper, the service life of the alloy sleeper is greatly prolonged, and the alloy sleeper can be used for coal mine railway transportation.
本发明涉及一种用于支撑钢轨的合金轨枕，属于煤矿铁道运输设备的技术领域。其包括轨枕主体、压板和紧固螺栓，轨枕主体的纵截面为梯形，轨枕主体两侧的下端有延伸边，压板通过紧固螺栓固定设于轨枕主体的上表面，压板两两对称设置，对称设置的两个压板用于卡接钢轨。该合金轨枕具有耐低温，耐腐蚀，耐振动，承受压力能力强，弹性、强度和耐久均匀的优点，解决了钢筋混凝土轨枕的刚度大、弹性差，道床承受的压力和振动加速度增大的问题，从而能避免道碴的粉化，不会造成轨道的下沉增大的问题，适合大跨度使用；且该合金轨枕使用合金钢材料，相比木枕轨枕或者钢筋混凝土轨枕使用寿命大幅度提高，该合金轨枕可效用于煤矿铁道运输使用。
