    摘要: A controller for a spring wing on a frog that utilizes a floating piston rod carrying a fixed piston valve and a free-moving piston head is provided. When the piston rod is actuated by the opening movement of the spring wing, the piston valve separates from the piston head briefly, allowing oil to flow through the piston head in a relatively unrestricted manner. The piston head is spring biased towards the piston valve; upon contact between the piston head and the piston valve, the oil flow through the piston head stops, helping to hold the spring wing in the open position. When the spring wing begins to close, the adjustable oil flow through the controller allows the piston rod to move at a controlled rate, thereby controlling the closure rate of the spring wing.

    摘要翻译: 提供了一种用于青蛙上的弹簧翼的控制器,其利用携带固定活塞阀和自由移动活塞头的浮动活塞杆。 当活塞杆由弹簧翼的打开运动致动时,活塞阀短暂地与活塞头分离,使得油以相对不受限制的方式流过活塞头。 活塞头朝向活塞阀弹簧偏压; 在活塞头和活塞阀接触之后,通过活塞头的油流停止,有助于将弹簧翼保持在打开位置。 当弹簧翼开始关闭时,通过控制器的可调节的油流可以使活塞杆以受控的速度移动,从而控制弹簧翼的关闭率。

    摘要: A movable point for a crossing frog for railway apparatus of great length, incorporated in long welded rails. The point (7) is comprised of a single steel element, which comprises integral seating cross members (8). The rigidity of the point varies along all its length from a minimum adjacent a thin forward portion (9) to a maximum adjacent a wide rear portion (10). The point is constituted by a piece of austenitic manganese steel. The point can be of cast steel or can be formed by laminating and/or forging, followed by machining.

    摘要: A process for producing a crossing frog with moving point (1) for very long railway switches incorporated in long welded rails. The frog also comprises a cradle (2) in two elements (3 and 4), one molded and the other not molded. The method comprises welding, on a point side of the frog, the molded element (3) of the cradle (2) to the rolling rails (7) of an intermediate track of a branch, fixing parts (5 and 5') to the moving point (1) so as to form the non-molded element (4) of the cradle (2); rigidifying the non-molded element (4); interconnecting, by means of a non-welded joint, the subassembly formed by the molded element (3) welded to the rolling rails (7) and the subassembly formed by the non-molded element (4) formed by the parts (5 and 5') and the moving point (1), and finally, welding the moving point (1) to the rolling rails (9) on a heel side of the frog.

    摘要: A process for producing a crossing frog with moving point (1) for very long railway switches incorporated in long welded rails. The frog also comprises a cradle (2) in two elements (3 and 4), one molded and the other not molded. The element (3) is of molded steel, of which at least the two ends (3A and 3B) on the point side and the two ends (3C and 3D) on the heel side are shaped as a rail profile, but only the rail profile of the two ends (3A and 3B) effectively serves for rolling. The non-molded element (4) is mainly made up of parts (5 and 5') produced integrally as rails and connected to the two ends (3C and 3D) on the heel side of the molded part (3). Neither the rail profile of the two ends (3C and 3D) nor the rail profile of the parts (5 and 5') effectively serves as rolling surface. The moving point (1) is produced integrally as rails of which all the upper faces effectively serve as rolling surface.
