Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
The utility model discloses a section of track device for single track railway tunnel double block formula ballastless track, including relevance portion and adjustment portion, the former sets up between the parallel rail in pairs for the interval of fixed rail in pairs and make rail in pairs link as an organic whole; the latter is arranged outside each rail of the pair of rails for adjusting the height and horizontal position of the pair of rails.
Specifically, as shown in fig. 1, the association portion 1 is a rectangular parallelepiped structure having connecting plates at both ends, the length of which is determined according to the design interval of the parallel rails M, and the connecting plates are connected to each rail M by fixing bolts.
The adjustment portion is located between every rail M's lateral wall and its drainage ditch side wall N that corresponds, including extension section 2.1 and adjusting block 2.2, and wherein, extension section 2.1 one end links to each other with rail M lateral wall, and the other end links to each other with adjusting block 2.2, for the convenience dismouting, all adopts the mode that fixing bolt links to each other above. As shown in fig. 2, a longitudinal through hole is formed in the center of the adjusting block 2.2, a fixing nut 2.3 is welded in the longitudinal through hole, a height adjusting screw 2.4 is screwed in the fixing nut 2.3, and the height of the parallel steel rail M can be adjusted by rotating the height adjusting screw 2.4. The bottom of the height adjusting screw rod 2.4 is sleeved with a protective sleeve 2.5 which is made of PVC plastic, so that the bottom of the height adjusting screw rod 2.4 is prevented from being damaged, and a protective effect is achieved. The outer diameter of the protective sleeve 2.5 is smaller than the diameter of the longitudinal through hole in the adjusting block 2.2, and the height of the protective sleeve 2.5 is based on the height adjustment of the steel rail M without being influenced. In addition, the bottom of each steel rail M is respectively provided with an elastic supporting block 3, so that the steel rail M is always in a supported state when the height of the steel rail M is adjusted.
