Description
Technical Field
The utility model relates to a track technique, in particular to not enough compensation arrangement of bent switch rail displacement based on single turnout switch.
Background
The turnout specifies the corresponding number according to different speeds of the train, and the larger the number is, the higher the speed of the train is. For example, a No. 41 high-speed turnout running on a high-speed rail has the straight passing speed of 350km/h and the lateral passing speed of 160 km/h; a No. 30 turnout, the straight passing speed is 250km/h, and the lateral passing speed is 120 km/h; the number 18 turnout is characterized in that the straight passing speed is 250km/h, and the lateral passing speed is 80 km/h; the number 12 speed-up turnout has a straight passing speed of 160km/h and a lateral passing speed of 50 km/h; the straight passing speed of the No. 12 common turnout is 120km/h, and the lateral passing speed is 50 km/h; no. 9 turnout, the straight passing speed is 120km/h, and the lateral passing speed is 35 km/h.

The large number of turnouts have large guide curve radius and correspondingly long switch rails, more than two groups of switch machines are needed, and the switch of the turnout switch can be realized only by adopting a transfer external locking mode (the transfer external locking mode means that two switch rails respectively act during switching).
However, due to the long length of the switch point of the large-size switch point, after the switch point is used for a period of time, due to the release of internal stress of the switch point, the curve guiding part of the switch point rebounds, so that when the side strand of the switch point is opened, the front part of the switch point is already attached, and the displacement of the curve guiding part at the rear part is insufficient, so that the track gauge of the curve guiding part is smaller than the normal value. Under the condition, when a train passes through the side strand of the turnout, the train runs by pressing the curved switch rail outwards and transversely by means of the rim of the wheel, so that the frictional resistance between the wheel and the curved switch rail is increased, the abrasion of the switch rail and the wheel is accelerated, the stability of the train passing through the turnout is also influenced, and certain potential safety hazards are caused. This problem is common in the areas of high train speed and high train density, especially in the high speed railway turnout.
