Abstract

Provided are a locking device (100) for a turnout structure, a turnout structure (200), and a straddle type rail system. The turnout structure (200) comprises a bogie (2012) and a base plate (202). The locking device (100) for the turnout structure (200) is configured to position the bogie (2012) to the base plate (202). The locking device (100) comprises: a supporting base (1) fixed to the bogie (2012), the supporting base (1) having a locking cavity (101), and the locking cavity (101) having a first cushioning member (121) therein; and a locking shaft (2) provided at the base plate (202) and movable in an axial direction thereof, the locking shaft (2) being inserted into the locking cavity (101) to fix the bogie (2012) to the base plate (202), and the locking shaft (2) being at least partially in contact with the first cushioning member (121) so as to provide a flexible cushioning effect and to reduce noise.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a locking device, a turnout structure with the locking device and a straddle track system with the turnout structure. Background technique [0002] The turnout is used to transfer the rolling stock from the main girder of the line to one of the multiple turnout girders of the line, and to meet the different traffic line requirements of the rolling stock through the switch switch. When the switch switch is in place, the locking device will be used The trolley supporting the turnout beam is positioned on the base plate, so that the position of the corresponding turnout beam is fixed for vehicles to pass through. In the related art, the reliability of locking the trolley by the locking device is low, and when the vehicle is running on the switch, the trolley shakes violently and the noise is relatively loud. Contents of the invention [0003] The present invention aim...
