Description
Technical Field

Background
At present, the construction of economic and smooth cross-type three-dimensional traffic by a medium and small traffic system becomes a novel development trend in a plurality of cities in China, and the three-dimensional cross-type rail traffic pattern of the cities at the present stage is a primitive model. In overhead rail transit, in order to ensure independent road rights, overhead level crossing is difficult to realize mainly by parallel, upward crossing and downward crossing, so that the utilization rate of air resources is low, the manufacturing cost is difficult to control, and the overhead level crossing system is very unfavorable for planning ground space resources.
Yun Ba is expressed as an 'electric bus running on an overhead', and the appearance of the electric bus has important significance for exploring the comprehensive development and utilization of the ground space of urban rail transit and promoting the construction of a three-dimensional traffic mode. When the rail transit of the space road network is constructed based on the cloud bar, the lines are orthogonal, various angles of oblique crossing are unavoidable, if the rail transit is not carried out in a flat crossing mode, the different faces of the lines can be intersected, and in order to ensure the limit requirement, the whole line can be raised, so that the engineering cost is improved, the space resource is wasted, the space resource planning is not facilitated, and meanwhile, the beautifying of the urban landscapes is also influenced.
In the prior art, a turnout structure designed for yunba is shown in fig. 11, and can realize a single-crossover function, a two-line integrated function and a curve segment and straight segment crossing function through corresponding translational movement of a movable guide beam, so that the requirement of overhead level crossing can be met to a certain extent. However, the switch structure described above is often only suitable for small angle two-wire intersections or large radius curves, and is not well suited when the two-wire intersections are nearly perpendicular or cross-orthogonal. On one hand, the movable guide beam becomes large, so that the manufacturing cost and the manufacturing process difficulty are increased; on the other hand, because the movable guide beam becomes larger, the translation difficulty is increased, the translation time is also increased to a certain extent, parameters such as the quantity configuration of lines, departure intervals and the like of Yun Ba are affected, and even after the intersection angle reaches a certain extent, the scheme of translating the movable guide beam cannot solve the problem, namely the turnout structure utilizing the movable guide beam in the prior art has a certain application limitation.
