Problems solved by technology

[0006] Even so, due to the high dynamic force and high stress of the operating load, and the rail is in a suspended state, the rail foot lacks restraint, the rail moves laterally, the rail foot twists, and the Pioneer fastener will still cause the rail torsion and the rail bottom slope during the train operation. The inaccuracy of the train, after the long-term operation of the train, the torsion of the rail makes the rail head slide in the horizontal direction and the wheel in the axial direction, causing the rail wave wear at a specific frequency, and the rail wave wear leads to a special noise-wave Grinding noise, which is 3~15dB larger than normal rolling noise, seriously affects people's riding comfort, endangers the health of passengers, deteriorates the environment along the line, and poses a great threat to the long-term operation of the train

Abstract

A rail torsion limiter for a fastener system. The fastener system includes a rail and an elastic block buckled on the lower jaw of the rail head of the rail. The elastic block is supported and positioned by a side panel fixed on a base plate under the rail. The rail The anti-torsion limiter includes a rail foot limiter clamped between the rail foot of the steel rail and the side panel for limiting the lateral movement and torsion of the steel rail. The invention adds a part to the existing fastener system, that is, the rail anti-torsion limiter, which is installed at the rail foot of the rail, and is used to restrain the rail foot of the rail, effectively restricting the rail foot The horizontal movement and torsional swing reduce the corrugation and squealing; at the same time, the fastening system retains the characteristics of simple structure and convenient installation and adjustment, which is very suitable for ballastless and ballasted track bed lines.

Description

technical field [0001] The invention relates to the technical field of railway tracks, in particular to a rail torsion limiter for a fastener system. Background technique [0002] Pioneer fastener (Vanguard) is a new vibration and noise reduction rail suspension fastener system developed by the British Pandrol company. Figure 12 shown. The fastener system adopts elastic wedge support on the lower jaw of the rail head, so that the bottom of the rail is separated from the rail bearing seat, and the rubber elastic block as an elastic support is supported and positioned by the side panel fixed on the foundation under the rail. Each fastening node of the Pioneer fastening system is supported by a cast iron base, two cast iron side panel brackets, two cast iron wedge block holders, two rubber elastic block elastic wedge rails, two cast iron side wings, an under-rail Safety support rubber pad and two spring clips. Under normal circumstances, the safety bearing rubber pad does no...
