Abstract

The invention belongs to the technical field of rail traffic, and particularly relates to a steel rail connecting device and a steel rail fixing structure. The steel rail connecting device comprises a support, a wedge block and an elastic piece, the support comprises a supporting part penetrating through the bottom of a steel rail and installation parts protruding out of the two ends of the supporting part, and the sides, close to the steel rail, of the installation parts are arranged in an inclined plane; the distance between the inclined plane and the steel rail is gradually decreased from top to bottom, the wedge block is connected with the supporting part through a fastening piece, one side of the wedge block is matched with the inclined plane, and the other side of the wedge block enables the elastic piece to abut against the rail web of the steel rail. The steel rail connecting device is arranged between steel rail fasteners, so that the torsional rigidity of the steel rail can be greatly improved; Compared with the prior art, the steel rail connecting device has the advantages that relative sliding of wheel rails is reduced when a vehicle passes through the steel rail in a curve mode, wheel rail corrugation caused by insufficient transverse rigidity of the steel rail in the running process of the vehicle is reduced, meanwhile, the steel rail connecting device is arranged between the steel rail fasteners, the steel rail with the size is in a suspended state, so that the steel rail connecting device has small influence on vertical rigidity of the steel rail; and the vibration reduction effect of the track is not influenced.

本发明属于轨道交通技术领域，具体是涉及到一种钢轨连接装置及钢轨固定结构，包括支架、楔块和弹性件，支架包括穿过钢轨底部设置的支撑部、凸出于支撑部两端设置的安装部，安装部靠近钢轨一侧呈斜面设置，斜面从上至下与钢轨的距离递减，楔块通过紧固件与支撑部连接，楔块一侧与斜面配合，另一侧将弹性件抵压至钢轨的轨腰上，本钢轨连接装置设置在钢轨扣件之间，可以极大的提高钢轨的扭转刚度，使得车辆曲线通过钢轨时轮轨相对滑动减少，减小车辆运行过程中由于钢轨横向刚度不够所引起轮轨波磨现象，同时由于本钢轨连接装置设置在钢轨扣件之间，尺寸的钢轨处于悬空状态，因此该钢轨连接装置对钢轨的垂向刚度影响较小，不会影响到轨道的减振效果。
