In addition, the rail clamp in the fastener is fixed only through the T-shaped bolt, so that the transverse stability is poor, and the transverse limiting capacity of the fastener system is further poor, and the rail gauge adjustment amount is small.
In addition, chinese patent publication (bulletin) No. CN215800728U also discloses a rail gauge adjusting structure, which comprises a base plate, wherein a rail is arranged on the base plate, a gauge block is symmetrically arranged on both sides of the rail, an elastic fastener for pressing the gauge block on the rail is arranged on the base plate, an adjusting part is symmetrically arranged on the base plate, the gauge block is positioned between the adjusting part and the rail, a fixing part is symmetrically arranged on the base plate, the adjusting part is rotationally connected on the fixing part, a plurality of clamping parts with different lengths are arranged on the adjusting part, the clamping parts are contacted with one side of the gauge block, and a positioning rod matched with the clamping part is arranged on the base plate. The gauge block in the steel rail gauge adjusting structure only depends on an elastic fastener, namely, a spring strip is pressed on a steel rail, and the installation stability is poor and the limiting capacity is very limited, so that the steel rail gauge adjusting structure also has the problems of limited transverse load bearing capacity and small gauge adjusting quantity.
Accordingly, it would be desirable to provide an adjustable gage double track fastener having a high lateral load carrying capability and gage adjustment.
