Background
Railway rails are often buckled by a fastener system, i.e., rail bottoms at both sides of the rail are buckled on the sleeper by spring bars to remain stable. However, in the switch heel position, because the switch rail is closer to the stock rail, an iron backing plate is required to be shared, and the elastic strips cannot be arranged respectively because the distance between the edges of the rail bottoms is smaller, double-side weights can only be welded on the backing plate between the two rails, and the inner sides of the two rails are buckled and pressed.
However, as the weight is rigidly buckled, the buckling force is greatly different from the elastic strip at the other side of the steel rail. Meanwhile, because the existing pressing plate is of a welding structure, when the turnout steel rail is worn or the geometric shape and position are bad, the track gauge is difficult to adjust, and only the steel rail or the whole turnout range can be replaced for common adjustment, so that the workload is large and the efficiency is low.
Moreover, when the steel rail is subjected to lateral force and has a side turning tendency, a large upward pulling force is generated at the welding seam at the bottom of the weight, and a welding opening phenomenon is often generated, so that the stability and the driving safety of the steel rail are affected.

the middle spring strip mechanism comprises a long T-shaped bolt penetrating through the iron base plate and the cover plate, and a first nut which presses the middle spring strip is sleeved on the long T-shaped bolt and is in threaded connection with the middle spring strip;
the side elastic strip mechanism comprises an iron seat, a short T-shaped bolt is fixed on the iron seat, a side elastic strip is sleeved on the short T-shaped bolt, and a second nut for pressing the side elastic strip is connected with the short T-shaped bolt in a threaded manner;
a boss is arranged in the middle of the iron backing plate, a self-locking plum blossom hole matched with the long T-shaped bolt is formed in the middle of the boss, and two sides of the iron backing plate are provided with round holes and backing plate bolts;
the track gauge adjusting piece comprises a long adjusting piece and N short adjusting pieces at the outer side, N is a natural number, the length of each short adjusting piece is identical to that of the cover plate, two ends of each long adjusting piece are bending sections, and the distance between the two bending ends is identical to that of the cover plate;
