Embodiment

[0018] Figure 1-Figure 2 It is shown that a specific embodiment of the present invention is: an integral track, the base 1 is a long strip integral structure, the upper part of the base 1 is symmetrically distributed with two protrusions 2 along the length direction, and the protrusions 2 The upper part is installed and covered with an inverted concave hat rail 3 adapted to form a railway track.

[0019] figure 1 It is shown that one end of the base 1 has an outward protrusion 7 , and the other end has a groove 8 matching the protrusion 7 . A plurality of drainage holes 9 are opened between the two protrusions 2 on the base 1 . Figure 1-3 As shown, the middle or lower part of the protrusion 2 is provided with a plurality of lateral mounting holes, and the cap rail 3 has a cap rail hole corresponding to the position of the mounting hole, and the bolt assembly 6 passes through the mounting hole and the cap rail hole to connect the cap rail 3 and the base 1 are installed and...

Abstract

This invention discloses a kind of integral track. Its base(1) is of long board integral structure, and the top of the base has 2 symmetric lugs along the length direction. On the lugs there are undercut hat-track covering lugs which are suitable for lugs, so the railway track is formed. The modular integral structure realizes the serial and standard railway track components and the batch and scale producing. Thanks to it, the working time of the railway can be reduced and changing and maintenance are more convenient. The hat-track directly touching the wheel can be founded or be made of the bended plates. The technology is easy, needing no big producing in big steel-smelting factories.

Description

Technical field [0001] The invention relates to a railway track. Background technique [0002] The existing railway tracks are composed of steel rails, sleepers, ballast beds, etc. There are many laying procedures, and the sleepers need to be placed and installed one by one. The construction procedures are complicated and random, the construction period is long, and replacement and maintenance are troublesome. The processing technology of the steel rail is high, and it must be produced by a large steelmaking plant. In short, the existing railway track has a long construction period and insufficient serialization and standardization of track components, which is not conducive to mechanized production and automatic laying, and cannot meet the urgent requirements of my country's rapid economic development for railway development. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an integrated ...
