Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] This embodiment provides a rail wear reducing device, refer to Figure 1-2 , including a guard rail and a plurality of guard rail brackets 3;
[0031] The guard rail comprises a straight section 21 and buffer sections 22 positioned at both ends of the straight section 21; the straight section 21 is parallel to the extension direction of the rail 1; the buffer section 22 is relatively far from the straight section 21 to the rail 1 directio...

The invention relates to a steel rail abrasion reduction device which comprises a protection rail and a plurality of rail protection brackets, wherein the protection rail comprises a straight sectionand buffer sections which are positioned at both ends of the straight sections; the straight sections are parallel to the extension direction of a steel rail; the buffer sections are bent for a presetfirst angle alpha in a direction far away from the steel rail relative to the straight section; the rail protection bracket comprises a fixing end and a support end; the fixing end and the support end are integrally formed to form an L-shaped structure; the fixing end is positioned below the steel rail and is fixedly connected with the bottom of the steel rail; the support end is positioned on one side of the steel rail and is fixedly connected with the straight section of the protection rail through transversely arranged horizontal bolts; the top of the protection rail is higher than the steel rail; an elastic adjusting gasket is arranged between the protection rail and the support end. According to the steel rail abrasion reduction device, the elastic adjusting gasket is arranged between the protection rail and the protection rail bracket, so that a certain buffer function on collision force of a wheel upon the protection rail is achieved; meanwhile, the distance between the protection rail and the steel rail can be adjusted, and the effectiveness of the abrasion reduction device can be ensured.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail wear reducing device. Background technique [0002] The small-radius curve section has always been a weak link in railway maintenance. The aggravation of its uneven wear not only increases the difficulty of maintenance, but also brings risks to traffic. When the train passes through a curved section, the rim of the guide wheel of the vehicle bogie presses the side of the outer rail head tightly, and a large friction force is generated between the wheel and rail. The work done by the friction force causes the side wear of the rail. The smaller the radius of the curve, the wear on the side of the outer stock The more severe it is, the more frequent the track change frequency will be in the small radius curve section. [0003] Wear-resistant steel rails and lubricators used in small radius sections are widely used in Beijing subways, which have a good effect on i...
