Joint technique for 45 degree sloping railway track

Abstract

A seaming technology for railroad track with 45degreeinclination can efficiently conquer attacking, shaking and hammering generated by the gap which is set aside when the road wheel rolls by the joint of traditional track in rail transport, and prolong loose time of roadbed under the joint. Only original 90degreeshearing against to the length direction is changed into 45degreeshearing during track production. Left-right track is symmetric and sharp angle is abated. Track is jointed by traditional method, but the gap H (expressed by figure) between rear and front track is equal to the length set aside in traditional joint method and inclination degree of left-and-right tracks is symmetrical so as to satisfy the designing demand. The invention is especially applied in comfortable and express trunk line demanded by passenger and high-cold zone and tundra influenced by shake sensitively.

Description

technical field [0001] The invention belongs to the improvement of rail joint technology in rail laying in railway construction, can effectively eliminate the vibration and noise during train running caused by the joint gap of the rails, and delay the time for the roadbed at the joint of the rails to loosen. Background technique [0002] The joints of the two front and rear rails are perpendicular to the direction of the train, and according to the climate conditions of the area, a certain reasonable gap is left for splicing. It solves the problem of thermal expansion and contraction of the rails, making the two rails Always keep parallel to facilitate the passage of trains, and also solve the problems of rail manufacturing, transportation and installation, but due to the existence of seam gaps, it is bound to cause shock, vibration and noise when the iron wheels pass here, especially when trains It is more serious when starting or driving at a slow speed. The obvious exampl...

[0002] The joints of the two front and rear rails are perpendicular to the direction of the train, and according to the climate conditions of the area, a certain reasonable gap is left for splicing. It solves the problem of thermal expansion and contraction of the rails, making the two rails Always keep parallel to facilitate the passage of trains, and also solve the problems of rail manufacturing, transportation and installation, but due to the existence of seam gaps, it is bound to cause shock, vibration and noise when the iron wheels pass here, especially when trains It is more serious when starting or driving at a slow speed, the obvious example is that the joints of the station rails are particularly prone to wear and tear, and the roadbed here is also particularly prone to loosening
