Abstract

A plug-in steel rail joint connector with no buttcover plate of the invention relates to a steel rail joint connector, which aims at the problems of the buttcover plate connection type that the buttcover plate steel rail bolt holes can be easily cracked, the steel rail joint can be easily worn out, damaged, overlapped, collapsed and peeled off; and aims at the problems of large assembly work volume, bad weight-bearing and deformation ability of the joints of the vibration damping clampboard connection type and the symmetric inclined plane or inclined trapezohedron connection type with steel rail joint clampboards. Both ends of a static rail (1) of the invention are symmetrically provided with plug-in grooves (3), one end of a moving rail (2) is provided with a plug-in rod (4), the shape of the other end of the moving rail is same with the section shape of a rail 60, plug-in grooves of two ends of the static rail (1) is internally provided with the plug-in rod (4) which is movably fit with the plug-in groove in transition, the lower end surface of the static rail (1) is provided with a base (5), and the relative positions of the static and moving rails are provided with conduction wires connection holes (7). The connector of the invention has strong weight-bearing ability, small work volume of adjusting and maintaining and good vibration damping ability, and is most suitable for high-speed railways, urban rails, subways, tunnels, bridges and cargo-passenger stations.

Description

technical field [0001] The invention relates to a rail joint connector. Background technique [0002] At present, the connection of railway rail joints at home and abroad is mainly in the form of fishplate connection. In recent years, there are also forms of vibration-damping splint connection and symmetrical inclined plane or symmetrical inclined plane with rail joint splint connection. The use of fishplates to connect rail joints has the following problems: 1. There are cracks in the rail bolt holes of fishplates. From the initiation of cracks, to the expansion and even fracture, it is caused by the fatigue damage of tens of thousands of impact loadings of rolling stock. Especially after the railway speed-up and heavy load, this situation is more serious. According to the statistics of the number of cracks in rail screw holes after the operation of electrified heavy-duty combined trains by the relevant railway departments, through the analysis of statistical data for four...
