An Omega Elastic Fastener System for Preventing Rail Overturning

Abstract

The invention belongs to the technical field of rail transit, and provides an omega elastic bar fastener system for preventing rail overturning. The proposed ω clip fastening system for preventing rail overturning includes ω clip (3), fastening bolt (5) and clip seat (6); the two high elastic arms (3b) of ω clip are directly buckled On the rail foot of the rail, or buckled on the rail foot of the rail (1) through the gauge block (2), the bottom surface of the middle ring (3a) and the bottom surface of the high elastic arm (3b) are the gauge block (2) The distance between the upper end face of the steel rail (1) and the rail foot is 10-15mm; the ω elastic strip (3) is connected as a whole with the elastic strip seat (6) through the fastening bolt (5). The invention prevents the further twisting of the rail, thereby avoiding the occurrence of a major accident of rail overturning, providing overload protection for train safety, and escorting the personal and property safety of passengers.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to an omega-clip fastener system for preventing rail overturning. Background technique [0002] Because of its adjustable buckle pressure, ω spring clips are suitable for road sections with different needs and are convenient for the adjustment of operating lines. At present, they have become the main type of railway fasteners at home and abroad; during the installation and maintenance of ω clip clips , all require "three-point contact", that is, when the fastener reaches the predetermined torque and is installed in place, the two elastic arms of the ω elastic strip and the middle ring are in contact with the rail foot or the upper surface of the gauge block at the same time; although the above requirements are to a certain extent This reduces the difficulty of installation and maintenance, but does not fully consider the issue of rail overload protection, that is, w...

Problems solved by technology

[0002] Because of its adjustable buckle pressure, ω spring clips are suitable for road sections with different needs and are convenient for the adjustment of operating lines. At present, they have become the main type of railway fasteners at home and abroad; during the installation and maintenance of ω clip clips , all require "three-point contact", that is, when the fastener reaches the predetermined torque and is installed in place, the two elastic arms of the ω elastic strip and the middle ring are in contact with the rail foot or the upper surface of the gauge block at the same time; although the above requirements are to a certain extent This reduces the difficulty of installation and maintenance, but does not fully consider the issue of rail overload protection, that is, when the lateral force on the rail is too large, the torsion angle of the rail is too large to a certain extent, and there is a danger of overturning. A huge hidden danger has been created, which seriously threatens the personal and property safety of passengers.
