Shuffling device and transferring method for turnout switch rails and stock rail assemblies on bridge

Abstract

The invention relates to a shuffling device and transferring method for turnout switch rails and stock rail assemblies on a bridge. The shuffling device consists of a rolling structure and a moving platform, wherein the rolling structure is formed by a plurality of square timbers and two roller assembly bodies placed on each square timber, and the moving platform is formed by separately placing a sliding steel girder on two rows of roller assembly bodies. The moving platform can make parallel movement on rollers of the roller assembly bodies through outside thrust. The turnout switch rails and the stock rail assemblies are placed on the moving platform, and can be transferred to a construction position from an unloading position on the bridge. According to the shuffling device and transferring method for the turnout switch rails and the stock rail assemblies on the bridge, disclosed by the invention, the problem that the switch rails and the stock rail assemblies cannot be transferred in place smoothly under the condition of no makeshift roads during bridge construction is solved. The shuffling device for the turnout switch rails and the stock rail assemblies on the bridge is used, so that the construction cost is reduced, and the construction efficiency is improved. The method disclosed by the invention is utilized, so that the construction is safe and reliable, and the condition that the deflection of the switch rails and the deflection of the stock rail assemblies cannot go beyond a design allowed range is guaranteed.

Description

technical field [0001] The invention relates to a tooling for a ballastless track laying turnout, in particular to a sliding device and a transfer method for a turnout point rail and a basic rail assembly on a bridge. Background technique [0002] The construction process of the turnout of the high-speed ballastless track is complex, requires high precision and is difficult. At present, in the construction of ballastless turnouts, cranes or gantry cranes are generally used to hoist and transfer the assembly of the point rail and the base rail, and the frog assembly of the core rail. The length of the point rail and basic rail assembly and the core rail frog assembly is 22m ~ 24m, it is easy to produce deflection deformation during hoisting. However, the deflection control requirements of the switch rail and basic rail assembly and the core rail frog assembly are quite strict. During the construction of ballastless turnouts at elevated stations, limited by construction con...

AI Technical Summary

Problems solved by technology

During the construction of ballastless turnouts at elevated stations, limited by construction conditions such as no construction access roads, it is more difficult to use cranes or gantry cranes to lift or transfer switch point rails, basic rail assemblies, and center rail frog assemblies, and the deflection deformation during lifting is even greater is hard to control

In addition, the use of cranes or gantry cranes to lift the tongue rail and basic rail assemblies, and center rail frog assemblies also has the following disadvantages: (1) The comprehensive costs of gantry crane rental, transportation, installation and dismantling, and daily maintenance are relatively high, resulting in increased engineering costs; (2) To install the traveling track of the gantry crane, it is necessary to drill holes on the beam surface or the bottom of the cable trough for fixing, which will cause damage to the beam body or the cable trough, leaving quality hidden dangers; (3) There are certain safety hazards in the operation of the gantry crane
