Problems solved by technology

[0003] The current suspension system is not very perfect, and the result of the internal stress distribution of the empty rail beam is not ideal. During the installation process, it is difficult to install the empty rail beam vertically, horizontally, and vertically. On-site installation, the installation environment is poor, and the installation quality cannot be guaranteed, which affects the realization of product functions

Abstract

The invention discloses a hanging type empty rail hinge shaft. The hanging type empty rail hinge shaft comprises a pier stud and an empty rail beam body, wherein a pier lug is arranged on the top endof the pier stud, beam lugs are arranged on both sides of the top surface of the empty rail beam body, and the pier lug is movably connected with the beam lugs by virtue of bearing shafts which are horizontally arranged. The invention further discloses a mounting method of the hanging type empty rail hinge shaft. The mounting method comprises the following steps of (S1) mounting the pier stud; (S2) mounting a support square tube and stainless steel; (S3) mounting a square block and a tetrafluorohydrazine sliding block; (S4) mounting a limiting plate; (S5) forming a first through hole; (S6) mounting a square bearing platform; (S7) lifting the empty rail beam body; (S8) mounting the bearing shafts; (S9) mounting adjusting shims; and (S10) mounting a fixed plate. The hanging type empty rail hinge shaft has the advantages that the rotation and sliding of the empty rail beam body are focused on the top of the beam, so that the installation is facilitated, and the sliding and rotation of thebearing shafts are integrated in a factory, so that the implementation of product functions and the quality guarantee are facilitated.

Description

technical field [0001] The invention relates to the technical field of rail vehicle suspension, in particular to a suspended empty rail hinge shaft and an installation method. Background technique [0002] Suspended empty rail technology is still in the initial stage of development in China. As a representative of small and medium-sized rail transit, suspended empty rail has the advantages of low construction cost and short construction period for solving the transportation needs of branch lines, auxiliary lines and backbone lines in small and medium cities. , Convenient construction and maintenance, relocation, and sustainable development, especially suitable for the transportation needs of urbanization with a large population and complex terrain in my country, adapted to the technical direction of urban rail development, and has a good market prospect. [0003] The current suspension system is not very perfect, and the result of the internal stress distribution of the empty...
