Description

Rail docking mechanism for railway rail construction

Technical Field

The utility model relates to a rail construction technical field specifically is a rail docking mechanism is used in railway rail construction.

Background

A railway track, known as a railway track, is a railway installation used on railway and cooperating with switches and turnouts to enable a train to travel without turning, and is generally composed of two balanced rails fixed on sleepers with ballast under them, and there are various ways of connecting the rails into a track. Most traditionally, twenty meters or so of rail are secured to ties with joints (also known as joints) between the rail sections. The british convention is that two rails will have joints in the same place, but the united states will be in a different place. The joint is jointed by a fishplate, which is a steel plate with the length of about sixty centimeters, and two ends of the steel plate are provided with four or six steel bolts for buckling small holes on the steel rails, gaps are specially reserved between the steel rails, the width of the steel rails is about 6mm, the steel rails are called telescopic joints, the small holes through which the steel bolts on the fishplate pass are oval, so that the steel rails can have expansion spaces in hot weather, and the expansion spaces are very important for the steel rails: although the problem of cold contraction and heat expansion can be solved, small seams left on the rails can generate 'click and click' sounds when a train passes by. Unless the rails are maintained very well, such jointed rails are not suitable for high speed trains to travel; passengers also feel that the running is not smooth, many developed countries of railways still use the rail joint on low-speed routes, non-important routes or branch lines, and fishplates are also common in routes lacking modernization investment. Most routes in the united states fall into this category and most still use wooden crossties, i.e., crossties that do not have room for expansion, once every time the temperature changes.

However, in the existing rail butt joint, due to the factors of expansion with heat and contraction with cold, certain gaps and expansion joints must be left on the two end faces of the rail butt joint, so that when a train runs on the rail, when wheels cross over the expansion joints of the rail, the wheels are instantly suspended and fall down, noise and vibration are generated, and the rest of passengers on the train is influenced, and therefore a rail butt joint mechanism for railway rail construction is urgently needed.
