Process for preparing cementing insulation joint in steel rail plant
The invention provides a preparation process of a cementing insulation joint in a steel rail plant, and relates to the technical field of rail manufacturing. The method comprises the steps that a clamping plate is prepared, the clamping plate is provided with a first clamping face, the first clamping face comprises an arc-shaped top face, a middle side face and an arc-shaped bottom face which are sequentially connected, the included angle between the arc-shaped top face and the middle side face is alpha, and the included angle between the arc-shaped bottom face and the middle side face is beta. Two steel rail bodies to be in butt joint are arranged between the two clamping plates, and insulating plates are arranged between the first clamping face of each clamping plate and the two steel rail bodies to be in butt joint; the steel rail body is provided with a second clamping face capable of being attached to the insulating plate, the second clamping face comprises a rail top bottom face, a rail web side face and a rail bottom top face which are sequentially connected, the included angle between the rail top bottom face and the rail web side face is gamma, the included angle between the rail bottom top face and the rail web side face is delta, alpha is larger than gamma, and beta is larger than delta. The clamping plate, the insulating plate and the steel rail body are fixed through bolts to form the insulating joint assembly. And cementing the insulating joint assembly. The process can improve the fatigue performance of the insulated joint.
本申请提供一种钢轨厂内胶接绝缘接头制备工艺，涉及轨道制造技术领域。其包括制备夹板，夹板具有第一夹持面，第一夹持面包括依次连接的弧形顶面、中间侧面和弧形底面，弧形顶面与中间侧面的夹角为α，弧形底面与中间侧面的夹角为β。在两个夹板之间布置待对接的两根钢轨主体，在每个夹板的第一夹持面与待对接的两根钢轨主体之间布置绝缘板；钢轨主体具有能与绝缘板贴合的第二夹持面，第二夹持面包括依次连接的轨顶底面、轨腰侧面和轨底顶面，轨顶底面与轨腰侧面的夹角为γ，轨底顶面与轨腰侧面的夹角为δ，α＞γ，β＞δ。利用螺栓固定夹板、绝缘板和钢轨主体以制成绝缘接头组件。胶接绝缘接头组件。该工艺能提高绝缘接头疲劳性能。
