Abstract

A single-drive-point joint turnout is provided with a driving beam, three driven beams and five trolleys located on corresponding turning tracks. The beams are in lap joint and hinged and then fixed on the corresponding trolleys. The trolley I is provided with a driving device and a locking device, wherein a positioning device is fixed on a base, the locking device and the positioning device are matched to achieve locking of the trolley I, and the driving device achieves movement of the trolley I. The front end of a long sliding arm is in rigid connection with the trolley II, the rail end of the long siding arm extends to the back portion of the trolley III and is hinged to the base through a sliding rotation pair. The front end of a middle sliding arm is rigid connection with the trolley III, and the tail end of the middle sliding arm extends to the position between the trolley III and the trolley II and is hinged to the long sliding arm through a sliding rotation pair. The front end of the short sliding arm is in rigid connection with the trolley IV, and the rail end of the short sliding arm extends to the back portion of the trolley IV and is hinged to the base through a sliding rotation pair. The rear end of the trolley V is hinged to the base. The manufacture and debugging difficulty of a joint turnout driving and locking system is reduced, and the reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit turnouts, in particular to an articulating turnout for a maglev transportation system or a straddle-type transportation system, in particular to a single driving point articulating turnout. Background technique [0002] For vehicles that straddle on rails, such as maglev vehicles and straddle vehicles, the switch for switching between two or more fixed rails can be integral or articulated. The integral turnout beam is a steel beam that can be flexed elastically. The main advantage of this kind of turnout lies in its linear continuity and good train passing performance. However, this kind of turnout is limited by the elastic modulus of the material and the deformation coefficient is small. In order to achieve a certain amount of switching, the length of the steel beam is required to be large, and the lateral rigidity due to deformation is small, which may cause a large force when the train pa...
